Understanding how to register a foreign construction company in Turkey is essential for any international contractor planning to bid on projects, mobilise a workforce, or establish a long-term presence in one of the world’s most active construction markets. Turkey permits full foreign ownership of construction entities, but the registration process spans multiple regulators, from the Trade Registry (MERSIS) and the tax office to municipal building-permit authorities and the Ministry of Labour and Social Security.
This guide walks through every stage of company registration in Turkey for foreign contractors: entity-type selection, document preparation, trade registry filing, bank and tax onboarding, construction permits, work-permit applications, and tender qualification, with realistic timelines, a full documents checklist, and a costs table calibrated for 2026 conditions.
Any foreign company or contractor intending to carry out construction works on Turkish soil must establish a registered legal presence. Turkey does not permit a foreign entity to simply sign a construction contract and begin works without a local registration. The requirement extends to general contractors, specialist subcontractors, engineering firms providing on-site services, and project developers executing build-to-suit or turnkey projects.
Turkish law offers four principal formation routes for a foreign contractor in Turkey. The right choice depends on project duration, procurement requirements, and whether the contractor intends to take on multiple projects over time.
| Structure | Best suited for | Can contract and invoice? | Minimum capital required? |
|---|---|---|---|
| Limited Liability Company (LLC / Ltd. Şti.) | Long-term presence; multiple projects; public and private tenders | Yes | TRY 50,000 |
| Joint Stock Company (JSC / A.Ş.) | Large-scale contractors; listed parent companies; bond/guarantee-intensive bids | Yes | TRY 250,000 |
| Branch Office | Single or defined-scope project; parent company retains direct liability | Yes, as extension of parent | No separate capital; parent must demonstrate financial standing |
| Liaison / Representative Office | Market research and coordination only | No, cannot contract, invoice, or earn revenue | None |
A liaison office in Turkey is unsuitable for construction contracting because it cannot generate revenue or enter into commercial agreements. The vast majority of foreign contractors choose an LLC for flexibility, or a branch office for a defined project scope. For a deeper look at construction law terminology, consult the dedicated glossary.
Before initiating company registration in Turkey, a foreign contractor should confirm that it meets the eligibility and pre-qualification requirements relevant to its target projects. These requirements vary depending on whether the contractor plans to bid on public tenders, private-sector contracts, or both.
Public procurement in Turkey is governed by the Public Procurement Authority (Kamu İhale Kurumu). Foreign contractors may participate in public tenders, but contracting authorities typically require a Turkish trade-registry certificate, proof of financial standing (audited financial statements, bank references), and a performance or tender bond. Membership in the Turkish Contractors Association (TMB) is not legally mandatory for all tenders, but TMB membership and ranking are widely used as bid-qualification benchmarks for large-scale infrastructure and housing projects. Contractors targeting bid qualification in Turkey’s construction sector should begin the TMB registration process in parallel with company formation.
Every Turkish-registered entity, whether LLC, JSC, or branch, must appoint at least one authorised representative resident in Turkey who can sign on behalf of the company, liaise with the Trade Registry, and receive official notices. For a branch office, the parent company must also issue a notarised board resolution authorising the branch and naming the local representative. Bank account opening and municipal filings will not proceed without this appointment.
The following numbered steps outline the complete registration and mobilisation sequence. Each step identifies who is responsible and provides a typical duration. The consolidated timeline table appears at the end of this section.
The foreign parent company, together with Turkish counsel, selects the appropriate entity type (LLC, JSC, or branch) based on the decision matrix above. Counsel then drafts the Articles of Association (for an LLC or JSC) or the branch-opening resolution and related board minutes. The articles must include the company’s trade name, registered address in Turkey, share capital, shareholder details, and the scope of activities, which should explicitly reference construction contracting, engineering, and related project services. For a branch, the parent company’s certificate of incorporation, articles of association, and a board resolution authorising the Turkish branch must be prepared.
All foreign-origin documents, certificates of incorporation, board resolutions, powers of attorney, and shareholder passport copies, must be notarised in the home jurisdiction and then apostilled (for countries party to the Hague Apostille Convention) or consular legalised (for non-Hague countries). Each apostilled or legalised document must then receive a certified Turkish translation by a sworn translator in Turkey. The duration of this step depends heavily on the home jurisdiction: apostille processing can take as little as two days in some European countries but up to two weeks in others.
Company registration Turkey filings are submitted through MERSIS (Merkezi Sicil Kayıt Sistemi), the centralised electronic registry system operated under the authority of the Ministry of Trade. The authorised representative or Turkish counsel creates a MERSIS record, uploads the incorporation documents, and submits the application to the relevant Trade Registry Office (Ticaret Sicil Müdürlüğü). Upon approval, the Trade Registry issues a registration certificate and the company’s establishment is published in the Trade Registry Gazette (Türkiye Ticaret Sicili Gazetesi). A tax identification number (Vergi Kimlik Numarası) is assigned simultaneously or immediately after registration. For branch office registration in Turkey, the process follows a comparable path, but the parent company’s good-standing certificate and branch-authorisation resolution must be filed alongside the application.
Processing typically takes one to seven business days, with many Trade Registry offices completing filings within one to four days.
Turkish banks require the trade-registry certificate, tax identification number, authorised signatory documentation, and shareholder identification before opening a corporate account. For an LLC, at least 25 per cent of the declared share capital must be deposited before registration (the remainder within 24 months). For a JSC, at least 25 per cent of the subscribed capital must be paid in before registration. The bank issues a capital-deposit confirmation letter, which is filed with the Trade Registry. Foreign construction companies should expect enhanced know-your-customer (KYC) due diligence, which can extend the account-opening process to up to ten business days at major Turkish banks.
The company’s appointed accountant or tax adviser registers the entity with the local tax office to obtain a VAT registration and to confirm the corporate-tax filing calendar. Separately, the company must register as an employer with the Social Security Institution (SGK, Sosyal Güvenlik Kurumu) before hiring any employee in Turkey. SGK registration is a prerequisite for issuing employment contracts, processing payroll, and, critically, applying for work permits for expatriate construction staff. These registrations are typically completed within one to seven business days.
Before commencing any physical construction activity, the company must obtain a municipal building permit (yapı ruhsatı) from the relevant municipality. The permit application requires the submission of architectural and structural project drawings, a site plan, environmental-impact-assessment (EIA) clearance (where applicable), and contractor qualification documents. Some municipalities maintain a contractor registry and may require the company to demonstrate technical capacity, insurance coverage, and occupational-health-and-safety (OHS) compliance. Construction permits in Turkey are processed at the municipal level, meaning timelines vary significantly, from approximately two weeks in smaller municipalities to twelve weeks or more in Istanbul, Ankara, or Izmir for large-scale projects.
Foreign construction companies deploying expatriate specialist staff must apply for work permits through the Ministry of Labour and Social Security (Çalışma ve Sosyal Güvenlik Bakanlığı). The employer submits an online application, including the employment contract, employer petition, and supporting documentation demonstrating why the position cannot be filled locally. Depending on nationality, the expatriate may need to apply for a work visa at a Turkish consulate before entry, or may apply for a work-and-residence permit after arrival. Typical processing times for a work permit in Turkey range from two to eight weeks. Expedited processing may be available for key personnel on large infrastructure projects.
Every expatriate holding a work permit must also obtain a residence permit, which is generally issued concurrently or shortly after the work permit.
For contractors intending to bid on public or private tenders, the procurement team must prepare and submit pre-qualification documents, including trade-registry evidence, financial statements, project references, and key-personnel CVs. A performance bond or tender bond, typically amounting to five to ten per cent of the contract value, must be arranged through a Turkish bank or an acceptable international bank with a Turkish correspondent. Bond issuance timelines depend on the bank’s credit assessment and the tender deadline.
| Step | Who does it | Typical duration |
|---|---|---|
| 1. Choose entity type and prepare incorporation documents | Foreign parent + Turkish counsel | 3–7 days |
| 2. Notarisation and legalisation (apostille / consular) | Shareholders / local notary / consulate | 2–14 days |
| 3. Trade Registry registration (MERSIS) and issue of registration certificate | Turkish counsel / Trade Registry | 1–7 business days (often 1–4) |
| 4. Deposit capital and open corporate bank account | Company representative + bank | 1–10 business days |
| 5. Tax office registration and VAT number | Accountant / tax office | 1–3 business days |
| 6. Employer (SGK) and payroll set-up | Accountant / Social Security office | 2–7 business days |
| 7. Municipal building permit and contractor licence | Local municipality / project GC | 2–12 weeks |
| 8. Work permit and residence permit for expatriates | Employer / Ministry of Labour / consulate | 2–8 weeks |
| 9. Tender qualification and performance bond submission | Procurement team / bank | 1–4 weeks |
Under favourable conditions, where documents are pre-legalised and a bank relationship is already in place, a foreign construction company can achieve full trade-registry status and tax enrolment within two to four weeks. Municipal permits and work permits then run in parallel, adding a further two to twelve weeks depending on project scale and municipality.
The documents needed for company formation, branch registration, municipal permits, and work permits are set out in the table below. Construction-specific documents, building-permit submissions, contractor references, and EIA approvals, are included alongside standard corporate-formation filings.
| Document | Notes |
|---|---|
| Parent company certificate of incorporation (apostilled or consular legalised) | Issued by home-country registrar; certified Turkish translation required. Typically must be dated within three months. |
| Articles of Association / Memorandum (with Turkish translation) | Drafted by counsel; notarised signatures of incorporators or shareholders. |
| Shareholder passport copies and proof of address | Notarised copies; translation required where originals are not in Turkish or English. |
| Power of attorney for authorised representative | Notarised and apostilled/legalised; required for Trade Registry filings and bank account opening. |
| Board resolution authorising branch (branch registrations only) | Must name the local representative and define the scope of branch activities. |
| Trade Registry registration certificate (Ticaret Sicil Gazetesi entry) | Issued by Trade Registry upon successful MERSIS filing. |
| Tax identification number (Vergi Kimlik Numarası) | Issued by tax office upon or immediately after trade-registry registration. |
| Bank declaration of paid-in capital | Bank confirmation letter; filed with Trade Registry for LLC and JSC formations. |
| Company stamp (kaşe) and signature declaration | Produced locally; required by banks, municipalities, and public authorities. |
| SGK employer registration documents | Completed upon employer registration with the Social Security Institution. |
| Contractor qualification documents (references, CVs, equipment lists) | Notarised project references; used for TMB registration, tender pre-qualification, and municipal contractor registration. |
| Site-specific documents (project drawings, EIA clearance, safety plan) | Required for municipal building permit; EIA clearance is mandatory for projects above regulatory thresholds. |
| Building permit application and owner/contractor declarations | Submitted to the municipal building authority; includes site plan, structural calculations. |
| Work permit application documents (employment contract, employer petition) | Filed with the Ministry of Labour and Social Security; may include labour-market-test documentation. |
| Performance bond / bank guarantee | Issued by bank; template and amount specified in tender documents. |
All foreign-language documents require certified Turkish translation by a sworn translator (yeminli tercüman). Originals or notarised copies must be retained, as multiple authorities, the Trade Registry, tax office, municipality, and banks, may each request a separate set.
Accurate timeline planning is critical for any foreign contractor in Turkey, particularly when registration must align with tender submission windows or project-mobilisation dates. The consolidated timeline table in the step-by-step section above provides per-step durations. This section highlights the key scheduling considerations and deadlines that affect the overall programme.
Trade Registry and tax enrolment. Under normal conditions, the core corporate registration (Steps 1–6) can be completed within three to six weeks from the date foreign documents are ready. If apostille or consular legalisation is delayed in the home jurisdiction, this window extends accordingly. Industry observers note that MERSIS processing in major cities (Istanbul, Ankara) typically remains within one to four business days, while smaller registry offices may take up to seven.
Municipal building permits. Construction permits in Turkey are subject to wide municipal variation. Istanbul’s metropolitan municipality processes often require six to twelve weeks for large projects, including review by the fire department, infrastructure agencies, and environmental authorities. Ankara and Izmir typically fall within four to eight weeks for mid-scale commercial construction. Contractors should submit building-permit applications as soon as trade-registry and tax enrolment are complete.
Work permits. A work permit construction Turkey application submitted to the Ministry of Labour and Social Security typically takes two to eight weeks from filing to decision. Contractors should factor in an additional one to two weeks for the consulate visa appointment (if the expatriate is applying from abroad) or the residence-permit issuance (if applying in-country). For large teams, staggered applications are advisable to avoid processing backlogs.
Tender deadlines. Public tender pre-qualification windows are published on the Electronic Public Procurement Platform (EKAP). Contractors should ensure that their trade-registry certificate, financial statements, and bank-guarantee capacity are in place at least four weeks before the tender submission deadline.
Statutory filing dates. Once operational, a Turkish-registered company must file corporate-tax returns quarterly (provisional) and annually, submit monthly VAT returns, and make monthly SGK premium declarations. Missing these deadlines triggers penalties and can jeopardise eligibility for public tenders.
The cost to register a foreign construction company in Turkey varies depending on entity type, project scope, and the volume of expatriate staff. The table below sets out the principal cost categories.
| Item | Typical amount (estimate) | Notes |
|---|---|---|
| Notary and translation fees (per shareholder) | TRY 500–3,000+ | Depends on number of documents and language pairs. |
| Trade Registry filing fee | TRY 1,000–5,000 | Varies by share capital and entity type; confirm with the relevant Trade Registry Office. |
| Minimum paid-in capital (LLC) | TRY 50,000 | At least 25% deposited before registration; balance within 24 months. |
| Minimum paid-in capital (JSC) | TRY 250,000 | At least 25% deposited before registration; balance per the articles. |
| Bank account opening and due diligence | Bank-specific (often no fee; deposit required) | Enhanced KYC for foreign companies may extend processing. |
| Municipal building permit fees | Variable, project-dependent | Calculated by municipality based on project scope, floor area, and land classification. |
| Work permit application fee | Variable (TRY-denominated) + consular fees | Fees differ by nationality, permit duration, and visa type. |
| Performance / tender bond | 5%–10% of contract value | Bank commission on guarantee issuance is a separate cost. |
| Legal and consultancy fees for formation | USD / EUR 1,500–10,000+ | Depends on scope: incorporation only, or incorporation plus permits plus tender support. |
Tax onboarding. Turkish-registered companies pay corporate income tax (standard rate: 25%), file monthly VAT returns (standard rate: 20%, with reduced rates for certain construction inputs), and make employer SGK contributions (approximately 20.5% of gross salary for employer share, subject to incentive reductions). Foreign contractors should also be aware of withholding tax obligations in Turkey, particularly on cross-border payments to the parent company or foreign subcontractors.
Several developments in 2026 have practical implications for foreign construction companies registering or mobilising in Turkey. The likely practical effect of these changes is an increase in both the upfront capital commitment and the administrative lead time for new registrations.
Minimum capital thresholds. Industry observers expect that the minimum share capital for an LLC (TRY 50,000) and a JSC (TRY 250,000), figures that have been referenced in Official Gazette publications and widely cited in 2026 practitioner guidance, will remain the baseline for the foreseeable future. However, contracting authorities and banks are increasingly applying their own, higher financial-standing thresholds when assessing foreign bidders for large infrastructure tenders.
Renewed procurement activity. Turkey’s 2026 construction pipeline, driven by earthquake-reconstruction projects, transport-infrastructure expansion, and urban-renewal programmes, has attracted heightened foreign-contractor interest. Early indications suggest that tender volumes on EKAP have increased, tightening pre-qualification windows and placing additional pressure on timely registration.
Bank due diligence. Turkish banks continue to strengthen KYC and anti-money-laundering procedures for foreign-owned corporate accounts. Contractors should anticipate longer account-opening timelines and prepare comprehensive beneficial-ownership documentation well in advance of mobilisation.
