Construction Company Formation in Turkey

Turkey’s Construction Sector

Turkey’s construction industry is among the largest globally by output. With continued urbanization, infrastructure investment, urban renewal programs, earthquake resilience upgrades, and active residential and commercial development, Turkey offers significant opportunities for construction businesses.

Foreign contractors have successfully operated in Turkey, participating in both private and public construction projects. The sector is regulated to ensure technical competence, financial capacity, and safety compliance.

Types of Construction Activities

Construction companies in Turkey typically operate in one or more of these segments:

Step 1: Form a Turkish Company

Construction operations require a Turkish legal entity. An LLC is suitable for most construction businesses:

• Minimum capital: 50,000 TRY (though construction operations need significantly higher practical capital)
• 100% foreign ownership permitted
• Formation: 5–10 business days

For large-scale construction requiring significant capital and/or equity partners, a JSC is often preferred.

The articles of association must specifically include construction, contracting, project development, and related engineering activities as business purposes.

See our LLC formation guide.

Step 2: Chamber of Commerce / Contractors Association Registration

Construction companies must register with:

• The local Chamber of Commerce (Ticaret Odası) — standard for all companies
• The Istanbul Chamber of Contractors (İstanbul İnşaat Müteahhitleri Derneği) or equivalent regional body (for public works eligibility)

Step 3: Contractor Classification for Public Projects

To bid for public construction contracts, contractors must be registered with the Public Procurement Authority (Kamu İhale Kurumu — KİK) and hold a valid contractor classification certificate (müteahhitlik yeterlik belgesi) issued under the relevant Ministry regulations.

Contractor Classification Groups

Turkish public procurement classifies construction contractors into workmanship groups (A1 through H) based on:

• Technical capacity and equipment
• Qualified engineering staff
• Financial capacity (equity, turnover history)
• Past project experience (reference projects)

Higher classification groups qualify for larger contract values. Foreign companies seeking to participate in Turkish public tenders must either:

• Directly obtain contractor classification through their Turkish entity, OR
• Form a joint venture (JV) with a qualified Turkish contractor

Electronic Public Procurement (EKAP)

All public procurement in Turkey is conducted through the EKAP (Electronic Public Procurement Platform — ekap.kik.gov.tr). Registered companies access tender announcements, submit bids, and receive award notifications through the platform.

Step 4: Required Licenses and Permits

Building Permit (Yapı Ruhsatı)

Construction of any new building or significant alteration requires a building permit issued by the local municipality. Applications must include:

• Architectural and structural drawings by licensed engineers
• Site title deed documentation
• Zoning compliance confirmation
• Soil investigation report (for areas designated as potentially earthquake-risky)

Occupancy Certificate (Yapı Kullanma İzni)

Upon completion, the municipality inspects the building and issues an occupancy certificate confirming compliance with the approved plans. Without this certificate, the building cannot be legally used for its intended purpose or sold to end buyers.

Earthquake Risk and Urban Renewal

Turkey has strict earthquake building code requirements following the 2023 Kahramanmaraş earthquakes. Buildings identified as “risky structures” under Law No. 6306 on Urban Renewal must be demolished and rebuilt. Construction companies participating in urban renewal projects must be registered in the Urban Renewal Registry.

Step 5: Professional Engineering Staff

Construction projects in Turkey require licensed engineers (inşaat mühendisi, mimar) registered with the relevant TMMOB (Union of Turkish Engineers and Architects Chambers) chamber:

• Civil engineers: Chamber of Civil Engineers (İnşaat Mühendisleri Odası — İMO)
• Architects: Chamber of Architects (Mimarlar Odası)
• Electrical engineers: Chamber of Electrical Engineers
• Mechanical engineers: Chamber of Mechanical Engineers

Foreign engineers can practice in Turkey if their qualifications are recognized by the relevant TMMOB chamber. This recognition process involves YÖK degree equivalency and chamber examination requirements.

Step 6: Insurance Requirements

Mandatory Employer Liability Insurance

Construction companies employing workers on construction sites must hold employer liability insurance covering workplace accidents.

Structural Defect Insurance

Sellers of newly built residential properties (contractors selling apartments) must provide structural defect insurance to buyers, covering structural defects for 5 years after delivery (per the Consumer Protection Law).

Professional Liability

Engineers and architects in Turkey are required by their chambers to hold professional liability insurance.

DASK (Compulsory Earthquake Insurance)

All buildings in Turkey (not just new construction) are required to have DASK compulsory earthquake insurance. Construction companies selling units must ensure DASK policies are in place before title deed transfer.

Tax Obligations

Corporate Income Tax

Construction company profits are subject to 25% corporate income tax. Long-term construction contracts (spanning more than one calendar year) have special tax accounting rules — completed contract method is not automatically applicable; consult a tax advisor.

VAT

Construction services are subject to VAT. Rates:

• 1% VAT: First sale of residential buildings up to 150 m² net area (social housing and standard housing)
• 20% VAT: Construction services for commercial projects, residential buildings > 150 m², and subcontracting services

Withholding Tax on Subcontractors

Main contractors paying subcontractors in certain categories must withhold income tax from service payments at the source. The current withholding rate for construction subcontractor payments is 3% (verify current rate at gib.gov.tr).

Frequently Asked Questions

Can a foreign-owned construction company participate in public tenders? Yes, through a Turkish-registered entity. The entity must obtain the relevant contractor classification certificate. For large public projects, joint venture structures with Turkish contractors are common.

What is the urban renewal program in Turkey? Urban renewal (kentsel dönüşüm) under Law No. 6306 involves demolishing and rebuilding buildings that fail earthquake safety standards. The government subsidizes a significant portion of costs for qualifying building owners. Construction companies registered in the urban renewal system can access this large pipeline of projects.

Do construction companies need separate licenses for different project types? Contractor classification certificates cover specified construction categories. A company with general building contractor classification can work on residential and commercial projects. Infrastructure projects (roads, bridges) require specific infrastructure contractor classification. Specialized activities (elevator installation, electrical, HVAC) require separate licensed subcontractors.

How long does contractor classification take? The initial classification application process typically takes 1–3 months depending on the classification group sought and completeness of documentation. Higher classification groups require more extensive documentation of financial capacity and reference projects.
