Turnkey Company Formation in Turkey (2026): A Foreign Investor's 14-Step Roadmap from First Contact to First Invoice

Regulatory note: As of 2026, this article is based on Law No. 4875 on Foreign Direct Investments, the Turkish Commercial Code No. 6102 (minimum capital amounts), the Tax Procedure Law No. 213 (potential tax ID and site inspection), the Electronic Signature Law No. 5070, the foreigner ID number (YKN) practice, and banks’ KYC/AML processes — prepared with a fully operational focus. Cost and duration figures are approximate; bank policies and fees may change.

“We’ll set up your Turkish company in a day.” You hear it from advisers a lot. It is not technically wrong — if the documents are ready, the Trade Registry registration really is fast. But the sentence misleads the foreign investor exactly where it matters: formation day and first-invoice day are not the same thing.

Before registration there is international preparation (a registered/virtual office address, apostille, translation); after registration there is an operational setup (the commercial bank account, digital authorities, e-invoice). The real question is not “when is the company formed?” but “when can I issue my first invoice?” This guide breaks the journey into three phases and 14 clear steps, focused on field reality. Its aim is twofold: to answer every question in your mind up front, and to show why this multi-layered process is — when handled correctly — predictable.

60-Second Summary: For a foreign investor in Türkiye, company formation is not a “day” but a 14-step process from first contact to first invoice. Good news: Both LLC and joint-stock-company (JSC) registration are completed via an apostilled power of attorney without flying in; even the JSC’s mandatory 25% capital-blockage account opens remotely by power of attorney. The bottleneck: the digital operation (e-signature, financial seal) requires a 99-prefixed foreigner ID number (YKN). The only physical requirement: the active commercial bank account you’ll collect invoices through — under the bank’s KYC rules the foreign signatory must, in practice, appear at the branch in person. The golden rule: appoint a Turkish-ID authorised person (a Turkish general manager) from the start and run the steps in parallel.

Why a “Process”, Not a “Day”?

Law No. 4875 on Foreign Direct Investments grants the foreign investor equal treatment with the domestic investor and frees up 100% foreign ownership (the monopoly limit of the old Law No. 6224 has been removed). Restrictions exist only in specific sectors regulated by international agreements or special laws. So in most sectors the legal door is wide open.

The real bottleneck is not the law but operations and the calendar. Foreign investors usually underestimate two things: (1) the apostille + sworn-translation logistics for documents obtained abroad, and (2) the compliance (KYC) process for the active commercial bank account through which invoices are collected. The correct expectation: your first step’s goal is not to form the company but to make the right structure decision.

3 Phases / 14 Steps: The Roadmap

The scary “how many weeks” question is not the point; what matters is completing these 14 steps in the right order and in parallel. Most of the elapsed time is not in your hands anyway (apostille/translation and bank KYC); managing the steps is our job.

The 14 steps at a glance:

1. Activity / NACE decision — what business you’ll do (B2C/B2B, export)
2. Company structure — LLC or JSC
3. Contract & share design — Class A/B/C shares, shareholders’ agreement, exit
4. Legal address / virtual office — remotely, by power of attorney
5. Ownership structure + general manager decision — Turkish-ID GM accelerator
6. Power of attorney + documents — apostille + sworn translation (most common delay)
7. Potential tax number — by passport, remotely
8. Capital blockage (JSC only) — by special power of attorney, remotely
9. MERSIS application — legal address + passport + tax number
10. Trade Registry registration + inspection — “formation day”, tax certificate active
11. Active commercial bank account — the only physical requirement + KYC
12. YKN / e-signature / financial seal — the key to the digital operation
13. KEP / UETS / e-invoice activation — the gateway to the first invoice
14. (Optional) E-TUYS authorisation — investment incentive certificate

Phase 1 — Decision & Preparation (Without Flying In / Desk-Based)

What lengthens the process is not these decisions but the documents waiting abroad for apostille — so decide quickly and get the documents moving immediately.

• 1. Activity (NACE) decision: What the company will do (B2C, B2B, export) determines the whole structure, capital and permit processes from the start. The wrong NACE means amendment cost and lost time after formation.
• 2. Company structure (LLC or JSC?): If you want flexibility for share transfers, bringing in investors and tender references, choose a joint-stock company (minimum TRY 250,000); for lower capital and simpler governance, an LLC (minimum TRY 50,000). Both can be set up remotely. (For the detailed breakdown, the logic in Sole Proprietorship or Limited Company? applies here too.)
• 3. Contract and share design: With more than one partner, Class A/B/C shares (voting / profit participation / management privilege) and pre-emption, tag-along/drag-along and exit rules must be written into the articles and a shareholders’ agreement from the start.
• 4. Legal address / virtual office (remote): A legal address is mandatory for the MERSIS entry and the tax site inspection. Without flying in, this is solved by signing a virtual office (or physical) lease via power of attorney.
• 5. Ownership structure + general manager decision: This is the most critical strategic decision. Appointing a Turkish-ID general manager at formation makes the process lightning-fast: a foreign manager must wait for a YKN from the Immigration Administration to obtain an e-signature and financial seal; a Turkish manager solves this instantly. Don’t worry about trust: the Turkish manager’s powers are clearly limited in the articles and signatory circular — for example, the authority to transfer money from the bank account can be switched off, granting only the authority to obtain the e-signature/financial seal and handle official-institution matters (a limited/Class-B signature). The operation opens, control stays with you. (Also: is the partner an individual or a foreign corporate partner/holding? A corporate partner needs the parent’s registry documents apostilled/translated too.)
• 6. Power of attorney + documents: The bilingual power of attorney we prepare is notarised in your own country, apostilled and sworn-translated. For countries party to the Hague Apostille Convention (most are), no consular legalisation is required — an apostille is enough. If there is a corporate partner, the parent’s certificate of good standing, articles, signatory circular and the board resolution authorising the Turkish incorporation are also prepared apostilled/translated; the power of attorney serves in lieu of the signature declaration. This is the most time-consuming step; start it immediately.
• 7. Potential tax number: A 10-digit (potential) tax number is obtained remotely through the Interactive Tax Office with your passport, without a residence permit or YKN. It is a precondition for incorporation.

Phase 2 — Formation & Registration (You Still Don’t Need to Fly In)

Your company is legally born here; but the digital and financial operation is not yet open.

• 8. Capital blockage (JSC only): In a joint-stock company, one quarter of the cash capital is blocked at the bank before registration. Key detail: this “temporary blockage account” is different from the active commercial account and can be opened remotely by special power of attorney, without you coming. (An LLC has no blockage; minimum capital is paid within 24 months after registration. For a non-public JSC adopting the registered-capital system the floor is TRY 500,000.)
• 9. MERSIS application: The application in the Central Registry System is made with the legal address + the foreign authorised person’s passport + (potential) tax number. A 99-prefixed YKN or e-signature is not required at this step.
• 10. Trade Registry registration and inspection (“formation day”): The articles are approved, chamber of commerce registration is done, and the Trade Registry registration takes place. Then a tax-office inspector, received by our representative at your legal address, signs the inspection report and your tax certificate becomes active. If documents are ready, the core registration is fast (in practice 7-15 business days).

Phase 3 — Operational Setup (The Road to the First Invoice)

The company is formed but cannot yet invoice. The real work is here.

• 11. Active commercial bank account (the only physical requirement!): Even though the JSC blockage account opens remotely, for the active commercial account used for operations, international transfers and collections, banks want to see the signatory in person (KYC and ultimate-beneficial-owner/UBO checks); a temporary blockage of TRY 50,000–150,000 may be requested. Sequence it right: once the core documents (articles, signatory circular, tax number) are ready, the bank starts a pre-approval process — typically 1–2 weeks. Confirm your travel date only after bank pre-approval arrives, so the account opening and all KYC are completed in a single 3–5 day visit. Practical tip: start with the state banks (Ziraat, Vakıfbank), which are more flexible on KYC.
• 12. YKN, e-signature and financial seal: For the company to join the electronic system (to be able to invoice), a financial seal is mandatory. This requires the authorised person’s Turkish ID number or a 99-prefixed YKN + a qualified e-signature. If you did not appoint a Turkish manager at Step 5, the foreign signatory must obtain a YKN from the Immigration Administration.
• 13. KEP, UETS and e-invoice activation: As soon as the financial seal arrives, a KEP (registered e-mail) address is obtained, the mandatory electronic notification (UETS) is opened via PTT, and the e-invoice/e-archive portal is activated. Now you can issue your first invoice.
• 14. (Optional) Incentive & support authorisation: If an Investment Incentive Certificate will be obtained, authorisation in the E-TUYS system is done with a qualified e-signature and a notarised undertaking sent to the Ministry via registered e-mail (KEP). Practical solution: instead of waiting for their own e-signature, the foreign manager can authorise a Turkish-ID representative (accountant/lawyer) as the E-TUYS user. If you are an IT/digital-services exporter, the E-Turquality (Stars of Informatics) programme launched by Presidential Decision No. 5447 (Official Gazette 20.04.2022) also applies: cash reimbursements on items such as software/app development, market entry, advertising-promotion, office/cloud rental and overseas units. Structured correctly, these supports recover a significant part of the operational cost. (The programme is active; the underlying text may have been amended — confirm the Ministry of Trade’s decision/circular in force before applying.)

Gökay GÜL tip: For a foreign investor, the single biggest accelerator is appointing a Turkish-ID authorised person. There is a chain dependency: the active commercial account waits for the tax ID, the financial seal waits for the YKN, and e-invoice waits for the seal. A Turkish general manager or representative obtains the financial seal instantly without waiting on YKN bureaucracy, opens the e-invoice system, and makes the company invoice-ready that same day. Many foreign investors, delighted that the company was “set up in a day”, then cannot invoice for weeks simply because they’re waiting on this digital-identity process. “You can form it without coming — JSC blockage included; but don’t underestimate the active commercial account and the need for a ‘Turkish-ID authorised person.’”

Field Case: Setting Up a JSC Remotely — Blockage or Commercial Account?

(The case below is anonymised from a real formation process.)

An investor from Europe wanted to set up a 100%-owned joint-stock company in Türkiye and thought, “I have to deposit capital at the bank for a JSC, so I must come.” Reality ran differently: the apostille and sworn translation of the power of attorney in their country took the first weeks (Phase 1).

During that time the potential tax number was obtained remotely by passport, and the JSC’s 25% capital-blockage account was opened by special power of attorney without the investor coming at all. MERSIS and Trade Registry registration were completed by power of attorney, and the inspection was done at the legal (virtual office) address — the company was formed, the tax certificate was active, but it still couldn’t invoice.

The real bottleneck emerged in Phase 3: collecting invoices required an active commercial account, and the bank required the signatory in person for KYC; meanwhile the financial seal was waiting on the investor’s YKN.

The fix came in two moves: (1) the investor came for the active commercial account in a single trip, with account and signature work concentrated into that visit; (2) a Turkish-ID general manager was appointed, so the e-signature and financial seal were obtained without waiting for the YKN and e-invoice was activated. Lesson: setting up a JSC remotely (capital blockage included) is possible; the only physical requirement is the active commercial account — confusing these two is the most common operational mistake in the market.

The Key Distinction and 2026 Cash Formation Costs

The key distinction: Incorporation = passport + power of attorney (remote). JSC capital-blockage account = power of attorney (remote). Active commercial account + KYC = appear in person (physical). Digital operation = YKN + e-signature. Mixing these four is the planning mistake foreign investors make most often.

2026 cash formation cost (approximate; for a single-shareholder LLC with TRY 50,000 capital, excluding capital):

On top of this come the monthly accountant fee (TÜRMOB tariff, workload-based) and the temporary blockage a JSC/bank may request (TRY 50,000–150,000; not an expense but blocked deposit). Figures are 2026 approximations; fees and bank policies may change.

Don’t forget the monthly run-rate: even if the company issues no invoice, you’ll have fixed compliance costs — the monthly accountant fee, virtual office rent, and stamp duties on VAT/withholding returns. Budget around this monthly band, not just the one-off formation. An anchor for foreign readers: TRY figures should be converted at the current rate; the total cash formation cost (excluding capital) typically sits around the ~USD 1,000–1,500 equivalent (the rate varies).

Frequently Asked Questions

Can I form a joint-stock or limited company without coming to Türkiye? Yes. For both types, incorporation, trade registry and chamber registration are completed through an apostilled and sworn-translated power of attorney. Even the JSC’s 25% capital-blockage account is opened remotely by special power of attorney. The only physical requirement is the active commercial bank account.

Is the JSC capital-blockage account the same as the active commercial account? No — and this is the most critical distinction. The temporary capital-blockage account is opened remotely by special power of attorney for registration. The active commercial account you’ll collect invoices through requires the signatory to appear in person for the KYC/UBO process.

What does incorporation (MERSIS) require? A legal address (virtual office included), the foreign authorised person’s passport, and a (potential) tax number from the tax office. A 99-prefixed YKN or e-signature is not required at this step.

Do I need to be a Turkish citizen for the financial seal and e-signature? No, but you need an ID: a Turkish ID number or a 99-prefixed foreigner ID number (YKN) + a qualified e-signature. The first invoice can only be issued after the financial seal is obtained.

What delays the first invoice the most? The active commercial account’s KYC process and the digital-identity wait (YKN → financial seal). A Turkish-ID authorised person largely removes this wait.

Is 100% foreign ownership possible in every sector? The general rule is yes (Law No. 4875). The exception is specific sectors regulated by international agreements or special laws; have your activity checked from the start.

Does forming a company automatically grant a work/residence permit? No — this is the most common misconception. Company formation and the work permit are separate processes. For the foreign partner to work in Türkiye as a “manager”, a separate work permit application is required, with its own conditions: as a rule, at least 5 Turkish citizens employed per foreigner and minimum capital/turnover criteria; some investor profiles (e.g. the Turquoise Card or qualifying investment) have exemptions. Thresholds are updated periodically and must be confirmed at the time of application. Practical solution: run formation and operations through a Turkish-ID general manager until the foreign partner’s work permit is issued — the company goes operational without waiting on it.

Action List

1. Set your first-step goal as “the right company structure”, not “formation”.
2. The most common delay is the power of attorney — start the power of attorney, apostille and virtual office immediately.
3. Obtain the potential tax number remotely by passport; for a JSC, open the capital blockage remotely by power of attorney too.
4. Concentrate the active commercial account bank visit into a single trip; prepare KYC documents in advance; start with a state bank.
5. Where possible, appoint a Turkish-ID authorised person; start the e-signature/financial-seal/e-invoice process in parallel through them.
