Setting Up a Construction Company in Slovakia as a Foreign Contractor: Complete 2026 Guide

A construction contract in Slovakia does not automatically require a Slovak subsidiary. It does, however, require a coordinated answer to several different legal questions. A foreign contractor may be able to perform a genuinely temporary project cross-border, operate through a registered branch, or use a Slovak s.r.o. The right structure depends on project duration, repeated activity, local staff, regulated work, VAT, permanent-establishment exposure, liability and the customer’s commercial requirements.

The most dangerous shortcut is to ask only whether the company has a “construction licence.” In Slovakia, company existence, trade authorisation, an individual’s professional qualification, project permission, worker compliance and tax registration are separate layers. Passing one layer does not satisfy the others.

The short answer

A foreign construction company does not always need to incorporate a Slovak company. An EU/EEA contractor may be able to provide a genuinely temporary service cross-border, subject to Slovak trade or professional notifications, worker-posting rules, VAT, BOZP and tax analysis. A branch may suit a direct, defined presence of the foreign parent. A Slovak s.r.o. is often more practical for recurring projects, local employees, local subcontractors, tenders, banking, liability separation and a long-term Slovak operation.

Incorporating an s.r.o. is only the corporate step. It does not replace the company’s required craft or bound-trade authorisations, a responsible representative, the personal authorisation of a site manager or engineer, the project’s public-law approvals, posting and immigration compliance, or tax and VAT registrations.

Before workers travel or the first invoice is issued, complete five project-specific reviews: the market-entry structure, exact work-scope authorisations, professional qualifications, worker status and documents, and VAT/PE treatment. Where direct Slovak operation is unsuitable, compare a Slovak s.r.o. and branch office before signing the project contract.

One project, six separate compliance layers

Foreign contractors often use “construction licence” to mean everything required to work. Slovak law does not work that way.

The practical consequence is simple: never mobilise solely because the Commercial Register shows a construction-related object of business.

Does a foreign construction company need a Slovak company?

Not in every case. A temporary cross-border route can be available, particularly to an EU/EEA contractor established and authorised in its home state. The word “temporary” is assessed from the activity’s duration, frequency, regularity and continuity. A six-month project is not automatically temporary for every legal purpose, and a project described as temporary may still create Slovak VAT, worker, trade-notification or permanent-establishment obligations.

A Slovak structure becomes more compelling where the contractor will:

• run several or repeated Slovak projects;

• hire people locally;

• maintain a project office, warehouse, machinery base or permanent management function;

• contract with local customers and subcontractors in its own Slovak operation;

• require local financing, tender guarantees or long-term bank facilities;

• retain significant site, defect or warranty risk;

• admit an investor or later sell the Slovak business; or

• build substance beyond a genuinely temporary service.

Market-entry options for a foreign contractor

ADVISON offers clean Slovak ready-made companies, VAT-registered ready-made companies and corporate handover support. The project must still be checked for its actual licensing, professional, worker and site requirements.

Can a Slovak construction company be foreign-owned and foreign-managed?

Yes. A Slovak s.r.o. may generally be wholly owned by foreign individuals or legal entities and may appoint a foreign natural person as managing director, subject to the usual eligibility, documentation, sanctions, beneficial-owner and registration checks. The director’s nationality does not itself grant the company a construction authorisation or the director a right to perform a regulated construction profession.

For a third-country director, corporate appointment, residence in Slovakia and work performed in Slovakia are separate questions. A person can in some cases manage remotely without Slovak residence; regular physical work in Slovakia may trigger immigration, tax and social-security analysis.

EU/EEA construction contractor

An EU/EEA contractor benefits from the freedom to provide services and freedom of establishment. That does not mean “no Slovak formalities.” For a temporary service, the contractor should confirm:

1. it is lawfully established and authorised in its home state;

2. the Slovak activity is genuinely temporary rather than stable establishment;

3. the relevant trade or regulated-profession notification is filed where required—Slovensko.sk states that a first temporary trade service is notified no later than the day before provision;

4. foreign qualifications are recognised or covered by the correct temporary-service declaration;

5. each posted employee is notified and has the correct A1/social-security evidence;

6. Slovak core employment and BOZP conditions are met;

7. Slovak VAT and invoicing are determined per supply; and

8. the domestic-law and treaty PE tests are tracked from the factual start of activity.

Repeated projects, an indefinite local office, local hiring and permanent market-facing activity point away from a purely temporary-service model and toward a branch or subsidiary.

Non-EU construction contractor

A third-country contractor is not prohibited from entering the Slovak market, but it cannot rely on EU free-movement rules as its default route. The company must assess a Slovak branch or subsidiary, applicable international agreements, trade authorisation, professional recognition and the immigration/work status of every person who will work in Slovakia.

The corporate vehicle may be 100% foreign-owned. Practical onboarding typically involves authenticated corporate documents, Slovak translations, UBO identification, sanctions screening, source-of-funds evidence, the project contract, expected turnover and worker/subcontractor details. A Slovak company does not automatically make third-country employees work-authorised; each worker’s nationality, residence status, employer and work arrangement control the route.

Slovakia’s Building Act in force in 2026

Act No. 25/2025 Coll. on Construction has applied since 1 April 2025. It replaced the main permitting framework under Act No. 50/1976 Coll. for new-regime cases. Spatial planning is regulated separately by Act No. 200/2022 Coll.

The current framework uses concepts including a decision on the building intent (rozhodnutie o stavebnom zámere), verification of the building project (overenie projektu stavby) and an occupancy certificate (kolaudačné osvedčenie). The building-intent proceeding and project verification are legally distinct, even where their practical timing is coordinated.

Municipalities generally act as building authorities, while regional offices of the Office for Spatial Planning and Construction have specified competences. The Construction Portal is operational and supports electronic filings and records, but the precise competent authority and permitted filing channel must be confirmed for the project.

Transition from the old regime

The new statute did not erase every pre-2025 project. Under Section 84 of Act No. 25/2025 Coll., matters filed or commenced by 31 March 2025 generally continue under the previous legislation. Later steps can also remain under the old regime where an older zoning decision or building permit creates the statutory transition link. Special transitional pathways also exist for certain older structures, including time-limited procedures running to 31 March 2029.

Therefore, do not determine terminology by the calendar alone. Ask:

• when the first relevant filing was received;

• whether an old-regime zoning decision or building permit exists;

• which subsequent procedure is being requested; and

• whether a special transition provision applies.

The official Office for Spatial Planning and Construction construction agenda provides the current Act and implementing decrees.

Project permit is not the contractor’s authorisation

A building-intent decision or verified project concerns the public-law readiness of a particular project. It does not prove that the contractor may perform every contracted activity. Conversely, a contractor’s trade authorisation does not allow it to build contrary to the verified project or without the required project process.

Before contracting, allocate who is responsible for:

• the building intent and project verification;

• land and third-party rights;

• statements of affected authorities and infrastructure managers;

• design changes and approval consequences;

• the site handover and site conditions;

• the construction diary and inspection readiness;

• commissioning, tests and as-built documentation; and

• occupancy/handover cooperation.

Contractor, site manager, supervision and designer are different roles

Under the 2025 Building Act, the contractor must be authorised to construct or remove the structure and must ensure specialist work is performed by appropriately authorised persons. It must build according to the verified project, use an authorised site manager, implement safety coordination, use suitable products, prepare inspections and hand over required documentation.

The site manager organises, manages, coordinates and controls work, manages the site and keeps the construction diary. This is a personal professional function, not merely the company’s trade-licence representative.

The construction supervisor normally protects the developer’s/investor’s interests where the law or project setup requires that function. An authorised civil engineer or authorised architect acts under the professional regime and chamber rules. The designer remains responsible for design work within the assigned scope.

A company’s responsible representative under the Trade Licensing Act is a different person: they ensure professional conduct of a craft or bound trade for the entrepreneur. One individual may meet more than one role only if all separate statutory conditions are genuinely fulfilled and conflicts, capacity and contractual duties are addressed.

What trade authorisations does a construction company need?

The answer depends on the exact work package, not the label “construction company.” The current Trade Licensing Act distinguishes free, craft and bound trades, while certain professional activities are outside the trade regime and governed by separate statutes.

A major 2025 change: general construction execution is now a bound trade

From 1 April 2025, “Zhotovovanie stavieb” and “Zhotovovanie inžinierskych stavieb” appear as bound trades in Annex 2 to the Trade Licensing Act. They require the prescribed evidence of education, experience and professional competence.

Older authorisations for the former free trade “Uskutočňovanie stavieb a ich zmien” benefit from transition rules only. Holders must align with the new qualification regime by 31 March 2029, otherwise the relevant entitlement expires. A company established or acquired in 2026 should not rely on an old online article that still calls general construction execution a simple free trade.

Common craft trades

Depending on scope, craft trades can include masonry, carpentry, roofing, sheet-metal work, insulation, plumbing and heating, flooring and certain installation/maintenance work. Electrical, gas, pressure, lifting, refrigeration and other reserved technical equipment may require bound-trade authorisation plus separate certificates, inspections or authorised personnel.

Project design, authorised engineering, authorised architecture, site management and construction supervision can fall under professional statutes rather than ordinary trade licensing. Energy certification and specialist inspections have their own requirements.

The safest method is a work-breakdown review: list each activity, who performs it, whether it is subcontracted, the machinery/equipment involved and who signs the final record. Map every line to the correct trade or professional regime.

When is a responsible representative required?

A Slovak legal entity performing a craft or bound trade must generally appoint a responsible representative who meets the statutory general and special conditions. Under Section 11 of the Trade Licensing Act, the representative is normally in an employment relationship with the entrepreneur, subject to limited statutory exceptions—for example, specified relatives in an individual business and, for a legal entity, a shareholder/member.

The responsible representative must meet residence/domicile and professional conditions, cannot be a member of the company’s supervisory/control body, and generally cannot serve more than one establishment without an exemption. Appointment and termination changes must be notified; if the role ends, replacement is generally required within 15 days.

Do not “borrow” another company’s responsible representative on paper. The person must have a real legal relationship, capacity and ability to ensure professional conduct. ADVISON should not be presented as supplying that person unless a separate verified service is agreed.

Are foreign construction qualifications automatically recognised?

No. EU/EEA recognition rules facilitate mobility, but they do not make every foreign certificate automatically valid for every Slovak regulated role. Slovakia’s current general recognition statute is Act No. 422/2015 Coll., not the superseded Act No. 293/2007 Coll. referred to in many older materials.

For a temporary regulated service, a prior declaration and evidence to the competent Slovak authority may be required. For establishment, a full recognition or chamber registration route may apply. The competent authority depends on the profession—such as the Slovak Chamber of Civil Engineers (SKSI), Slovak Chamber of Architects or another designated body.

The Ministry of Education recognition portal explains academic and professional recognition routes. Confirm the exact Slovak regulated activity, the competent authority, required translations, professional experience, good standing and whether compensation measures can be imposed.

Can a foreign site manager work in Slovakia?

Potentially yes, but not merely because the person is employed as a site manager abroad. The contractor must verify whether the Slovak function is regulated, whether temporary cross-border provision or establishment applies, and whether the person needs recognition, registration or a certificate from the competent Slovak body.

Then separately verify the person’s posting or local employment, A1/social-security status, right to work and reside, tax position, BOZP training and practical availability on the site. Professional recognition does not replace immigration or worker-posting compliance.

Permanent establishment for a Slovak construction project

A permanent establishment (PE) is a Slovak taxable presence of a foreign enterprise. It is not the same as a registered branch. A contractor can have a PE without registering a branch, and branch registration does not settle the treaty analysis.

Under Section 16(2) of the Slovak Income Tax Act, a building site or place of construction or assembly projects is treated as a PE where the activity of the non-resident taxpayer or its related persons exceeds six months. The same provision contains fixed-place, service and dependent-agent routes.

However, a ratified double-tax treaty has priority. The treaty with the contractor’s residence country may use 12 months, six months, another period, or wording that includes supervisory or installation activities. Never use “12 months” as a universal Slovak answer.

How to count the period

Track the factual project from preparatory work at the site through completion, not only the invoice date. Temporary interruptions normally do not restart the clock. A coherent project can remain one unit despite multiple contracts, phases or locations. Related enterprises and subcontractor time can be relevant under domestic law, treaty wording and anti-fragmentation principles. Artificially splitting one commercial project is not a reliable solution.

Also test PE before the construction threshold is met. A recurring office, workshop, warehouse, machinery base or project-management location can constitute another fixed place. A person who habitually concludes contracts or plays the principal role leading to contracts can create dependent-agent exposure.

When PE exists, register as required, attribute arm’s-length profit to Slovak functions, assets and risks, maintain records and apply transfer pricing to dealings with head office and related parties. Obtain the actual treaty from the Ministry of Finance treaty section and document the conclusion before mobilisation.

Corporate tax, accounting and the 2026 minimum tax

A Slovak s.r.o. keeps Slovak double-entry accounting and is taxed as a Slovak resident company. A foreign contractor with a Slovak PE must determine and report the profit attributable to the PE and maintain adequate Slovak records.

For 2026, the corporate income-tax rate is generally:

• 10% where taxable revenues do not exceed EUR 100,000;

• 21% for companies outside the 10% and 24% bands; and

• 24% where taxable revenues exceed EUR 5 million.

The minimum corporate tax is generally EUR 340, EUR 960, EUR 1,920, EUR 3,840 or EUR 11,520 depending on taxable-revenue bands, subject to statutory exceptions and reductions. Construction contractors should budget for tax compliance even in a loss year.

Related-party machinery rental, management fees, financing, guarantees and subcontracting require arm’s-length pricing and documentation. For a broader owner-level explanation, see How Is a Slovak s.r.o. Taxed in 2026?.

Construction-site PE is not the only tax risk

Project teams often track only days on site. The tax file should also assess:

• a fixed project office, warehouse or workshop;

• recurring use of the same premises;

• management or decision-making in Slovakia;

• a dependent agent concluding or driving contracts;

• service-PE wording in the applicable treaty;

• linked projects and related enterprises;

• personnel tax and payroll obligations; and

• VAT establishment, which is a separate legal test.

The corporate choice and tax result are connected but not identical. Using a foreign company without a branch does not prevent PE; incorporating an s.r.o. does not eliminate tax issues for the foreign parent if it also performs work directly.

VAT on construction work in Slovakia

Services connected with Slovak immovable property generally have their place of supply in Slovakia. The next question is who accounts for the tax and whether the supplier must register. Do not answer by project label alone.

Slovakia’s standard VAT rate is 23% in 2026. Domestic reverse charge for construction work under Section 69(12)(j) applies only when the statutory conditions are satisfied, including that both supplier and recipient are Slovak VAT payers and the supply is construction work, a building/part supplied under a works-type contract, or goods with installation, classified in CPA Section F.

VAT workflow before the first invoice

1. Identify the legal supplier and customer.

2. Determine whether the supply is a service, goods with installation, rental or mixed supply.

3. Confirm the property location and place of supply.

4. Check whether the supplier has a Slovak establishment participating in the supply.

5. Validate both parties’ Slovak VAT status on the supply date.

6. Classify the output under CPA, including whether it is in Section F.

7. Test domestic or foreign-supplier reverse charge separately.

8. Review advances, invoice wording, control statement and VAT-return reporting.

9. Revisit the conclusion when scope or subcontract chain changes.

ADVISON provides Slovak VAT registration support. Evidence of real economic activity may be needed; see the voluntary VAT registration evidence guide.

Sending foreign workers to a Slovak construction site

A contractor must identify the real legal arrangement for each worker. A posting is not the same as a business trip, local employment, temporary agency assignment or labour-only supply.

For a genuine posting, the home employer keeps the employment relationship and temporarily sends the employee to Slovakia to perform a service. The hosting employer must notify the Slovak National Labour Inspectorate and observe Slovak host-state rules. If a subcontractor merely supplies people who take day-to-day instructions from the general contractor, the arrangement may be reclassified as temporary assignment or unlawful labour supply.

Posting notification and site documents

The foreign employer should file the NIP posting notification before work starts as the operational rule, including employer details, worker identity and nationality, dates, worksite, type of service and a Slovakia-based contact person. Changes must be notified without delay.

The employer must make available, in the required form, evidence of the employment relationship, working-time records and wage-payment documents. The site file should also include identification, A1 or applicable social-security evidence, right-to-work/residence documents where relevant, BOZP training, medical fitness where required and proof of qualifications.

Slovak working conditions

Posted workers benefit from the Slovak hard core of employment conditions where it is more favourable or mandatorily applicable, including remuneration/minimum wage rules, working time, rest, leave, BOZP, certain accommodation conditions and rules for temporary assignment. Sectoral higher-level collective agreements must be checked where legally applicable.

After 12 months, broader Slovak employment law applies; a reasoned notification can extend the period to 18 months if filed before expiry. The long-term rule does not transform an invalid posting into a valid one and does not settle tax, immigration or social security.

A1: what it proves—and what it does not

Portable document A1 confirms which EU/EEA/Swiss social-security system applies. In a qualifying posting, the worker can generally remain in the home system for up to 24 months. The home-state institution issues the document, and it should be available for inspection.

A1 is not:

• a work permit;

• a residence permit;

• a worker-posting notification;

• a tax exemption;

• a trade licence; or

• recognition of a professional qualification.

The posting must meet EU coordination conditions, including a real relationship with the posting employer, significant activity by that employer in the home state and the restriction against replacing another posted worker. People who normally work in two or more states use a different coordination analysis. EHIC supports necessary healthcare access but is not a substitute for the employer’s full BOZP, insurance and medical obligations.

See the Social Insurance Agency A1 guidance.

EU/EEA workers and third-country workers

Can Ukrainian workers work on a Slovak construction site?

Yes, where each worker has a valid route—such as Slovak temporary protection with applicable employment rules, a Slovak employment/residence authorisation or another statutory basis. Ukrainian citizenship is not itself a permit, and one worker’s status cannot be copied to the whole team. Verify employer, job, worksite, expiry, reporting and health-insurance position individually.

The National Labour Inspectorate’s third-country employment guidance and Ukraine guidance are starting points; immigration counsel should confirm the route before travel.

The 183-day rule does not automatically prevent Slovak wage tax

Tax treaties commonly allow the home country alone to tax employment income only if all treaty conditions are met: the employee’s Slovak presence stays within the treaty day limit, remuneration is paid by or on behalf of an employer not resident in Slovakia, and the remuneration is not borne by a Slovak PE. Treaty wording and counting period vary.

The economic-employer analysis can matter where the Slovak customer or operation directs, controls and economically bears the labour. A worker may have Slovak tax/payroll obligations before day 184. Conversely, exceeding 183 days does not decide every issue without the treaty and residence analysis.

Maintain travel days, attendance, payroll allocation, recharge agreements, reporting lines and the PE analysis together. Social security under A1 and income tax under a treaty are separate systems.

Local employment and payroll

A Slovak s.r.o. hiring workers locally becomes a Slovak employer, with employment contracts, payroll tax, social and health insurance registration, wage reporting, working-time records, occupational health and BOZP duties. A foreign enterprise can also acquire Slovak employer obligations without incorporating an s.r.o.

Accommodation, travel allowances, rotations, bonuses and machinery/vehicle benefits should be designed with payroll and tax treatment in mind. Informal cash payments or nominal self-employment create severe evidence and illegal-employment risk.

BOZP and responsibility on the construction site

Construction is a high-risk workplace. Act No. 124/2006 Coll. and Government Regulation No. 396/2006 Coll. impose employer and temporary/mobile-site duties. Coordination by the developer or safety coordinator does not release each employer from responsibility for its own workers.

Before site entry, the employer should have:

• risk assessment and safe work procedures matched to the actual tasks;

• understandable induction and toolbox training;

• required personal protective equipment;

• medical fitness and specialist training where required;

• machinery, lifting and reserved-equipment documents;

• fall, excavation, electricity, fire and traffic controls;

• emergency, first-aid and incident procedures;

• working-time and attendance control; and

• a process for reporting and investigating accidents.

Where several employers work on one site, allocate interfaces, site rules and coordination. The investor/developer may need a safety coordinator and safety plan under the mobile-site rules. The National Labour Inspectorate site-safety guidance should be used with project-specific BOZP advice.

Avoid illegal employment and disguised labour supply

A written “subcontract” label will not protect the parties if the facts show workers are supplied as labour. Warning signs include the customer assigning individual workers, directing their shifts and methods, providing all tools, approving leave, replacing workers one-for-one and paying only by hours without contractor output risk.

A genuine subcontract should define an output or work package, management responsibility, price mechanism, quality and defect risk, own supervision, tools/equipment allocation, worker compliance and evidence of delivery. General contractors should verify subcontractor authorisations, workers, notices, A1/immigration, payroll, BOZP and insurance—then audit the actual site practice.

Construction contracts in Slovakia

The Slovak Commercial Code’s contract-for-work framework is commonly used for B2B construction. The contract should be built around the project documents rather than a one-page price quotation.

Key provisions include:

• precise scope, exclusions and hierarchy of documents;

• responsibility for design and approvals;

• fixed price, measurement or cost-reimbursable mechanism;

• advance payments, milestones, invoicing and VAT;

• change-order authority and form;

• valuation of additional and omitted work;

• access, site conditions and employer-caused delay;

• programme, milestones and extension of time;

• testing, inspection, handover and completion evidence;

• defects, remedies and separately agreed warranty;

• retention, performance security and advance-payment guarantee;

• parent-company guarantee where required;

• insurance and subcontractor coverage;

• contractual penalties, damages and liability caps;

• suspension, termination and step-in rights;

• governing law, courts or arbitration; and

• language and notice mechanisms.

Do not state one universal statutory warranty period for every B2B construction contract. Statutory defect liability and an agreed guarantee are different. FIDIC forms are used in Slovak infrastructure and international projects, but they are contractual forms, not Slovak statutes; Particular Conditions must align with mandatory Slovak law, procurement documents and project allocation.

Managing change orders, records and payment evidence

Many disputes begin with work that was orally requested but never validly ordered. Define who may instruct a change, required notice, pricing records and the effect of proceeding without approval. Keep daily evidence: construction diary entries, attendance, measurements, photographs, delivery notes, tests, inspection requests, obstruction notices and correspondence.

Retention is not a substitute for a clear acceptance process. State when retention is deducted, conditions for release, whether it can be replaced by a bond, and how VAT/accounting treats the underlying supply. Align subcontract flow-down obligations with the main contract without transferring obligations the subcontractor cannot control.

Subcontractor-chain controls

Before appointment, verify:

• Commercial and Trade Register status;

• exact trade and professional authorisations;

• responsible representative and key personnel;

• VAT status and invoice classification;

• worker employer, nationality and documentation;

• posting notices, A1 and immigration status;

• payroll, time and wage evidence;

• BOZP training, incidents and insurance;

• capacity, references and conflicts;

• sanctions, UBO and adverse history; and

• bank account and payment-instruction controls.

During performance, monitor who is physically present, who directs them and whether the work matches the approved subcontract. Contractual indemnities do not replace statutory supervision or protect against work stoppage.

Public procurement, ZHS and RPVS

Foreign economic operators may compete in Slovak public procurement, subject to the tender’s qualification, evidence, exclusion, electronic-communication and security requirements. The European Single Procurement Document can provide preliminary self-declaration; the contracting authority may later require supporting evidence and translations.

The List of Economic Operators (ZHS) can simplify repeated proof of personal status but is not the same as registration in the procurement platform and does not prove technical or financial capacity for a particular project. See the Public Procurement Office ZHS page.

The Register of Public Sector Partners (RPVS) is a separate transparency regime. Where the contractor meets the statutory status and transaction thresholds, registration requires verification of the ultimate beneficial owner by an authorised person. Tender documents may also regulate subcontractors, references, guarantees, conflicts and sanctions. A new or ready-made company does not automatically inherit qualifying references or satisfy a tender.

ADVISON’s verified corporate services include RPVS registration and ZHS support shown on its service navigation; confirm the project-specific procurement mandate separately.

Construction waste and environmental obligations

The Waste Act and Decree No. 344/2022 Coll. impose specific construction and demolition-waste duties. Identify by law and contract who is the waste holder, who classifies it, where it is stored, which authorised person receives it and who keeps records and files reports.

Hazardous waste, contaminated soil and asbestos require specialist handling. Excavated soil and demolition material should not be moved or reused informally. The developer and contractor should allocate duties, but a contract cannot exclude statutory liability toward authorities.

Large or sensitive projects may require EIA, water, nature, air, heritage or other approvals. These are project-specific and should be included in the permit-responsibility matrix.

Insurance and guarantees

No single policy covers all construction risks. A practical programme may include general liability, construction all risks, erection all risks, professional indemnity for design/engineering, machinery and motor cover, environmental liability and legally required worker/social insurance.

Check named insureds, subcontractors, territorial scope, project description, policy period, deductibles, exclusions, defects, vibration, underground services, hot works, testing and cross-liability. Investors and lenders may require performance, advance-payment or warranty guarantees. A bank account does not guarantee a bank will issue these instruments; arrange facilities before the contractual deadline.

Financial transaction tax and banking workflow

Slovak entities and qualifying Slovak business presences must assess the financial transaction tax. The usual 2026 rates include 0.4% on debit transactions capped at EUR 40 per transaction, 0.8% on cash withdrawals and an annual EUR 2 charge for a payment card, subject to the statute’s taxpayer, account and exemption rules. Foreign accounts used by a Slovak taxpayer can require self-assessment rather than eliminating the tax.

Banks perform independent KYC. Expect requests for ownership/UBO data, source of funds, project contract, counterparties, forecast turnover, worker/subcontractor model and large-payment rationale. Formation never guarantees account opening, guarantees or credit. See Opening a Bank Account for a Foreign-Owned Slovak Company.

Registered office, project office, construction site and Slovensko.sk

These are four different things:

• Registered office: the legal address and physical corporate mail point.

• Project office/place of business: the actual operational office, warehouse or management base.

• Construction site: the place where the project is carried out and site rules apply.

• Slovensko.sk electronic mailbox: the official electronic channel used by Slovak public authorities.

A virtual office can provide a lawful registered address and physical-mail handling. It does not replace a site, warehouse, operational substance, professional qualification or monitoring of the electronic mailbox. ADVISON provides registered offices in Slovakia, Virtual Office Nitra and the SeatSpace client portal.

Foreign directors must ensure the company’s Slovensko.sk mailbox is accessible and monitored. Official messages can have legal effect independently of ordinary email. Use the Slovensko.sk mailbox guide for foreign directors and formally delegate access rather than sharing personal credentials.

Mandatory e-invoicing preparation

Slovakia’s planned mandatory e-invoicing and reporting changes affect system design, customer/vendor master data and accounting integration. Construction companies have extra complexity from advances, milestones, reverse charge, retentions, change orders and high invoice volumes. Review the Slovakia mandatory e-invoicing guide when configuring the 2027-ready workflow.

Buying a ready-made construction company

A clean ready-made s.r.o. gives the buyer an existing corporate vehicle. A VAT-registered ready-made company adds an existing VAT registration. Neither is a universal “construction licence.”

Before acquisition, verify:

• all objects of business against the planned work breakdown;

• whether general construction execution is correctly authorised under the post-2025 bound-trade rules;

• craft and bound trades and each responsible representative;

• whether a responsible representative will remain after transfer;

• personal certificates of site managers, engineers and inspectors—these do not transfer with shares;

• VAT status, filings and real-business evidence;

• employees, payroll, notices and immigration;

• BOZP records, accidents and inspection history;

• contracts, disputes, retentions, guarantees and defects;

• subcontractors, debts, tax arrears and enforcement;

• public-procurement exclusions, ZHS/RPVS status and references;

• bank accounts, guarantees and credit limits; and

• Slovensko.sk users and unread official messages.

An existing operating construction company requires deeper legal, tax, labour and technical due diligence than a clean shelf company. A reference belongs to the entity only if the underlying history is real and tender rules accept it; a personal professional authorisation always remains with the person.

Practical scenarios

Scenario 1 — Polish contractor with a six-month project

A Polish company wins a defined six-month Slovak works package and sends its own employees. A Slovak company is not automatically required. The contractor should test the temporary cross-border trade/professional route, file any first-service notifications, notify posted employees, obtain A1 documents, apply Slovak working conditions and prepare the site BOZP file.

For tax, Slovak domestic law uses a six-month-exceeded construction-site PE test, but the Slovakia–Poland treaty must be read before concluding whether treaty protection applies. VAT depends on customer status, supplier establishment and the exact CPA-classified supply. Project extension and connected follow-on work must be tracked.

Scenario 2 — Austrian general contractor establishing a Slovak subsidiary

An Austrian group plans recurring projects, local managers, employees and a Slovak subcontractor network. A Slovak s.r.o. often provides clearer contracts, payroll, local accounting, liability separation, tender participation and later investment or sale. It still needs the correct bound/craft trades, responsible representatives, authorised site personnel and project permissions.

The parent–subsidiary relationship requires transfer pricing for management, equipment, financing and guarantees. Parent personnel seconded to the s.r.o. need worker, tax and social-security analysis.

Scenario 3 — Ukrainian-owned Slovak construction company

A Ukrainian owner can own a Slovak s.r.o. and a qualifying foreign person can act as director. The company should plan authenticated documents, UBO/source-of-funds evidence, bank KYC, Slovensko.sk access and accounting. Each Ukrainian worker then requires an individual status check—temporary protection, residence/employment route or other lawful basis—plus payroll, insurance and BOZP.

The owner’s nationality is not a risk conclusion. The operative questions are ownership transparency, documented funding, sanctions screening, management facts and lawful worker status.

Scenario 4 — German specialist subcontractor

A German company performs a short technical installation. It should classify the activity: installation may involve a bound trade, reserved technical equipment, a recognised professional function or a Section F VAT supply. Workers need posting notices and A1. A short duration may avoid a construction-site PE under the applicable treaty, but a recurring workshop, project office or dependent agent can create another PE route.

The subcontract should define output responsibility rather than simply provide labour by the hour.

Scenario 5 — Foreign contractor bidding for a public project

The bidder should map tender eligibility, equivalent foreign evidence, ESPD/JED, translations, references, economic and technical capacity, guarantees, subcontractors and electronic communication. ZHS can simplify personal-status proof but does not replace project criteria. RPVS may be required when the statutory public-sector-partner conditions are met.

A ready-made company without relevant references, financing or personnel does not become tender-ready merely by changing shareholders.

How should a foreign construction contractor enter Slovakia?

Use this decision sequence:

1. Is the project genuinely temporary and cross-border? If yes, test the temporary-service route; if repeated or stable, compare branch and s.r.o.

2. Will there be local staff, premises, equipment base or recurring contracts? If yes, a Slovak structure and PE/employer setup become more likely.

3. What exact work will be performed? Map each line to free, craft, bound or separately regulated activity.

4. Who will perform regulated functions? Verify responsible representative, site manager, engineer, supervisor and specialist certificates separately.

5. Who employs each worker? Choose posting, local hire or lawful assignment and complete notices, A1 and immigration before site entry.

6. Where is VAT due and who accounts for it? Test the parties, supply, establishment and CPA classification.

7. Will the project or related presence create PE? Apply Slovak domestic law and the specific treaty, not a generic 12-month rule.

8. Can the corporate and bank setup support the contract? Confirm insurance, guarantees, cash flow, accounting and Slovensko.sk.

Can a foreign contractor manage the project remotely?

Corporate ownership and many filings can be handled remotely, but construction is not a purely remote business. The contractor needs physically available site management, qualified personnel, worker documentation, BOZP controls, diary and inspection cooperation. Banks may require additional identification or presence, and professional-recognition or immigration steps may constrain timing.

A registered office can be remote-managed. It cannot replace the site or operational presence. Build the remote workflow around formal delegated access, local contact persons and clear escalation—not shared credentials.

Common mistakes foreign construction contractors make

• Assuming an EU company can start any construction activity without Slovak checks.

• Confusing company incorporation with a construction authorisation.

• Relying on the old free-trade “construction and changes thereto” label after the 2025 reform.

• Treating the responsible representative as the site manager.

• Assuming a foreign professional certificate is automatically effective.

• Confusing a project permit with contractor permission.

• Sending workers before the NIP notice and document file are ready.

• Treating A1 as a work permit or tax exemption.

• Applying the 183-day rule without its other treaty conditions.

• Treating every PE treaty as a 12-month treaty.

• Resetting the PE clock through artificial contract splitting.

• Applying reverse charge to every construction-related invoice.

• Using labour-only subcontractors that operate as unlicensed staff suppliers.

• Ignoring BOZP interfaces across several employers.

• Treating a virtual office as operational substance.

• Buying a ready-made company without checking bound trades and representatives.

• Assuming VAT registration proves past or future VAT compliance.

• Relying on ordinary email instead of Slovensko.sk.

• Signing before insurance and bank guarantees are effective.

What should we do if workers are already on site without the correct setup?

Do not expand the activity until the facts are controlled. A safe response is:

1. identify every entity, worker, nationality, employer, contract and worksite;

2. verify the contractor’s trade authorisations and each personal qualification;

3. check posting notices, A1 and long-term-posting dates;

4. verify residence, work permits, temporary protection and information-card duties;

5. review BOZP induction, risk controls, medical fitness and site coordination;

6. identify the real start date for VAT, PE, payroll and employer obligations;

7. preserve contracts, attendance, time, wages, invoices, payments and site records;

8. correct registrations or filings where legally possible;

9. stop any arrangement that is in substance illegal labour supply; and

10. involve Slovak labour, immigration, tax and construction-law specialists where sanctions or deadlines may be running.

Late filing does not automatically erase an earlier breach or sanction. Do not manufacture backdated documents.

Planning a construction project in Slovakia?

Tell ADVISON:

• the contractor’s home country and whether it is EU/EEA or third-country;

• the exact construction work and project location;

• expected start and completion dates and contract value;

• number, nationality and employer of workers;

• whether workers will be posted or hired locally;

• whether the customer is a Slovak VAT payer;

• which regulated professions or technical equipment are involved;

• whether local premises, equipment or repeated projects are planned; and

• whether you need a new company, ready-made company, VAT registration, registered office, bank-account setup or Slovensko.sk support.

ADVISON can then identify the corporate and market-entry services that fit the project and flag the construction, labour, immigration, tax or qualification issues that require a separate specialist review. Contact ADVISON.
