Checklist

Company Formation Document Checklist

In Turkey, formation files usually come back not because a document is missing but because it was prepared the wrong way — an apostille on a loose sheet, a translator not on the court list, a PoA missing an authority. This tool lets you tick your way through the file, with progress stored in your browser. It also sets out the six-step process, the NACE code guide and the seven rejection reasons with their fixes.

Tick items off as you prepare the formation file — your progress is stored in this browser, not on a server. It picks up where you left off if you gather documents across several days.

1 · Foreign natural person shareholders

One set per foreign shareholder and each foreign-national director.

2 · Foreign legal entity shareholders

Only applicable when a foreign parent company is the shareholder, not an individual.

3 · The seven authorities the PoA must contain

A missing authority stalls the process midway — the capital deposit authority especially.

The six-step formation process

Timings and costs assume a single-shareholder Ltd. Şti. registered in Istanbul in 2026.

NACE code selection guide

The wrong NACE code means the wrong VAT rate, blocked incentives and denied technopark applications. Choose the code that matches your real revenue-generating activity.

SectorPrimary NACE codeNote
Software / SaaS development62.01.01Computer programming activities. Required for the 100% service export deduction (CTL 10/1-ğ) and technopark eligibility.
E-commerce / online retail47.91.01Retail sale via internet. If you also warehouse and dispatch, add a wholesale code. VAT rates depend on the product category.
Consulting (management / IT)70.22.02Business and management consultancy. The service export deduction applies only to consultancy delivered to non-resident clients and used outside Turkey.
Import / export trading46.90.01Non-specialized wholesale trade. Product-category subcodes must be added if regulated. Customs registration follows separately.
Digital marketing / advertising73.11.01Advertising agencies. The service export deduction is available for campaigns delivered to foreign clients whose end market is outside Turkey.
Light manufacturingNACE 10–33Sector-specific code depending on the product. Manufacturing often qualifies for regional investment incentives; check your city’s incentive tier before filing.

The seven most common rejection reasons

The recurring issues across foreign-founder files — each has a specific preventive fix.

  1. Apostille on a separate sheet, not physically bound to the document

    Fix: Instruct your home-country apostille authority to staple, seal or ribbon-bind the apostille directly to the document. Confirm before shipping.

  2. Translation done by a translator not on the Turkish court’s registered list

    Fix: Use only yeminli tercüman (Turkish court-registered sworn translators). Foreign “certified” translations are systematically refused.

  3. Power of attorney missing specific authorities

    Fix: Include all seven authorities — especially “depositing share capital”. A PoA missing formation-account authority stalls the capital deposit. (The account itself still requires the signatory to sign in person.)

  4. NACE code does not match the declared business purpose in the Articles

    Fix: Align your MERSIS activity codes with the business purpose text word by word. A software company with a “consulting” NACE code will be flagged.

  5. Trade name conflict or use of restricted terms without approval

    Fix: Avoid “bank”, “insurance”, “holding”, “university” and “foundation” unless you hold the underlying regulatory approval. Have two backup names ready.

  6. Articles of Association missing required clauses under the Commercial Code

    Fix: Ensure your AoA covers company purpose, capital and share structure, representation and signature rules, general assembly and duration. Do not use foreign-country AoA templates.

  7. Capital deposit receipt amount does not match the declared capital (JSC only)

    Fix: Deposit exactly 25% of the declared JSC capital into the blocked formation account, with no rounding down. The bank receipt must state the exact TRY amount.

Post-incorporation compliance calendar

The first two months determine whether your company is operational or stuck in administrative limbo.

Month 1 — Get operational

  • Week 1Tax office visit (yoklama) — the inspector verifies your registered address exists. Have signage, meeting space and someone present.
  • Week 1–2SGK employer file activation — required within the statutory window even if you have no employees yet.
  • Week 2E-signature (e-imza) issuance for the director — required for all state portal filings.
  • Week 2–3E-arşiv fatura registration (mandatory), plus e-fatura / e-defter enrolment if thresholds apply.
  • Week 3–4Corporate bank account opened and operational — the authorized signatory must sign in person. Set up multi-currency access if you will receive foreign revenue.

Month 2 — First reporting cycle

  • By day 26First monthly VAT (KDV) declaration filed by your SMMM, covering month 1 activity.
  • By day 23Monthly withholding tax (muhtasar) and SGK filings for any salary, rent or professional fees paid.
  • OngoingFirst provisional corporate tax planning session with your SMMM — set up the structure for the CTL 10/1-ğ service export deduction if applicable.
