How to Form a Company in Turkey 2026: Minimum Capital, One‑stop Office & Remote‑incorporation Checklist

Last reviewed: 30 April 2026

Turkey continues to attract record levels of foreign direct investment, and understanding how to form a company in Turkey 2026 is the essential first step for any inbound founder, corporate group or portfolio investor targeting this market. Stricter enforcement of minimum capital requirements at the trade registry, combined with the rollout of the One‑Stop Office regime that merges company, tax and residence registration into a single coordinated workflow, means the incorporation landscape looks materially different from even twelve months ago.

This guide consolidates every procedural stage, from MERSİS registration and notarised powers of attorney through to bank capital‑deposit certificates and post‑incorporation compliance, into a single, actionable company formation checklist for Turkey that foreign investors can follow whether they are incorporating in person or entirely remotely.

Quick Answer, Can Foreign Investors Form a Company in Turkey in 2026?

Yes. Under Law No. 4875 on Direct Foreign Investment, foreign natural persons and legal entities receive equal treatment with Turkish nationals when establishing and operating a company. There is no requirement for a local partner, and foreign shareholders may hold 100 % of the equity in most sectors. The principle of equal treatment means that the procedural steps, MERSİS registration, trade registry filing, tax enrolment, are identical regardless of the investor’s nationality.

Two important caveats apply. First, certain regulated sectors (defence, broadcasting, aviation) impose foreign‑ownership caps or require additional licences. Second, company registration does not automatically grant a Turkish residence or work permit; investors must apply separately through the Directorate General of Migration Management once the company is formed.

Which Company Types Are Used by Foreign Investors, Quick Comparison

The Turkish Commercial Code (TCC) recognises several entity forms, but three dominate foreign‑investor practice in 2026. The comparison table below summarises the key differences in capital, governance and typical use case to help you choose the right structure before you begin the company formation Turkey 2026 process.

Industry observers expect the LLC to remain the default vehicle for the majority of foreign‑investor company formations in Turkey, given its lower capital threshold and streamlined governance. A JSC becomes the practical choice where equity fundraising, share‑option plans or a future public listing are envisaged.

2026 Minimum Capital Rules & Enforcement, What Changed

The statutory minimum capital figures in the TCC have not changed in nominal terms, but the way trade registries enforce them has tightened considerably in the 2026 cycle. Understanding the minimum capital Turkey 2026 enforcement regime is critical because an incomplete or non‑compliant capital filing is now the single most common cause of application rejection for foreign investors.

What the trade registry now requires

• Bank deposit certificate at filing. For an LLC, the full subscribed capital (or the portion due at incorporation as stated in the articles of association) must be deposited into a bank account opened in the company‑in‑formation’s name. The bank issues a capital deposit certificate (sermaye blokaj mektubu) confirming the funds are blocked until registration completes.
• JSC staged deposit. A JSC must deposit at least 25 % of the subscribed share capital before registration; the balance must be paid within twenty‑four months of incorporation.
• Documentary proof of source. Banks conducting KYC on the capital deposit increasingly request evidence of the source of funds, wire transfer confirmations, audited accounts or declarations, particularly for foreign‑origin capital exceeding TL 500,000.
• Consequences of non‑compliance. If the deposit certificate is missing, incorrectly addressed or shows a discrepancy with the articles, the trade registry will reject the application outright. Rectifying the deficiency and re‑filing typically adds five to ten working days to the timeline.

Capital amounts at a glance (2026)

The likely practical effect of this enforcement shift is that investors should coordinate their bank account opening and wire transfer well in advance of the target filing date, allowing at least five business days for the Turkish bank to process incoming international transfers and issue the certificate.

One‑Stop Office Turkey (2026 Rollout), How It Changes the Formation Flow

The One‑Stop Office initiative, rolled out progressively through trade registries in Turkey’s major commercial centres, consolidates what were previously separate agency interactions into a single, coordinated intake. For foreign investors learning how to form a company in Turkey 2026, the One‑Stop Office represents both a genuine time‑saver and a new documentation discipline.

What the One‑Stop Office consolidates

• Trade registry registration (company formation itself).
• Tax office enrolment, taxpayer identification number (TIN) and initial VAT registration are triggered automatically upon trade registry approval rather than requiring a separate application.
• Social security registration, employer registration with the Social Security Institution (SGK) is initiated at the same filing window.
• Notification to the Ministry of Industry and Technology for FDI statistical tracking under Law No. 4875.

Practical pitfalls for foreign documents

The One‑Stop Office Turkey workflow imposes tighter document‑format requirements because multiple agencies receive the same submission simultaneously. Foreign corporate shareholders should ensure that:

• All apostilled or consularly‑legalised documents are accompanied by a certified Turkish translation prepared by a sworn translator (yeminli tercüman).
• Passport copies are notarised and, where the investor is a legal entity, the chain of authority (board resolution → power of attorney → signatory identification) is complete and internally consistent.
• The MERSİS system record and the physical documents presented at the trade registry match exactly, discrepancies in shareholder names, capital figures or registered‑address details between the digital record and the paper file will trigger rejection under the coordinated workflow.

Early indications suggest that the One‑Stop Office has reduced the total multi‑agency onboarding period from a typical fifteen‑to‑twenty working days down to seven‑to‑twelve working days for applicants whose documentation is fully compliant at first submission.

Step‑by‑Step Company Formation Checklist Turkey, Remote & In‑Person Routes

The following numbered checklist covers every stage of the formation process for a foreign investor incorporating an LLC, the most common entity. Adjustments for a JSC or branch are noted where relevant.

1. Pre‑incorporation checks

• Confirm that the target business activity is open to 100 % foreign ownership (check sector restrictions).
• Decide on entity type (LLC vs JSC vs branch) and number of shareholders.
• Appoint a Turkish‑qualified legal representative or law firm to act on your behalf if you will not be present in Turkey (see PoA section below).

2. Name reservation & articles of association

• Reserve the proposed trade name through the MERSİS system. The name must be unique in the relevant trade registry district.
• Draft the articles of association (esas sözleşme for a JSC; şirket sözleşmesi for an LLC), specifying registered capital, shareholder contributions, management structure and company purpose.

3. MERSİS registration Turkey

• Create or update the MERSİS record online. All company data, shareholders, capital, registered address, manager appointments, must be entered digitally before the physical trade registry filing.
• Foreign individual shareholders require a Turkish tax identification number (TIN) to register on MERSİS; this can be obtained through the local tax office or, in 2026, via the One‑Stop Office intake.

4. Notary & power of attorney (remote incorporation Turkey)

• If the investor is abroad, a notarised and apostilled (or consularly‑legalised) power of attorney must be prepared, granting the Turkish representative authority to sign the articles of association, open the bank account, deposit capital and file with the trade registry.
• The PoA must be accompanied by a certified Turkish translation. See the dedicated PoA checklist below.

5. Bank deposit & capital certificate

• Open a temporary bank account in the company‑in‑formation’s name at a Turkish bank.
• Transfer the required capital and obtain the sermaye blokaj mektubu (capital deposit certificate).
• For international wire transfers, allow at least five business days for funds to clear and the certificate to be issued.

6. Trade registry filing

• Submit the complete application package, articles of association, MERSİS confirmation, capital deposit certificate, notarised shareholder documents, PoA (if remote) and chamber of commerce registration forms, to the competent trade registry office.
• Under the One‑Stop Office regime, the trade registry simultaneously triggers tax and social security registrations.

7. Tax ID, social security & corporate bank account

• Collect the company’s tax identification number issued via the One‑Stop Office.
• Convert the temporary capital‑deposit account into a full operating corporate bank account (KYC documentation for the company and its beneficial owners will be required).
• Register as an employer with SGK if the company will hire staff.

MERSİS & Trade Registry Turkey: Forms, Document List & Common Rejections

MERSİS (Merkezi Sicil Kayıt Sistemi) is the centralised electronic registry through which all company formation Turkey 2026 filings must pass. The digital record created on MERSİS is the single source of truth that the trade registry checks against the physical documents you present.

Document checklist, foreign individual shareholder

• Notarised passport copy (apostilled or consularly legalised).
• Certified Turkish translation of passport.
• Turkish tax identification number (TIN).
• Two biometric photographs.
• Proof of residential address (home‑country utility bill or bank statement, translated and notarised).

Document checklist, foreign corporate shareholder

• Certificate of incorporation or equivalent (apostilled, with certified Turkish translation).
• Board resolution authorising the investment and appointing a signatory (apostilled, translated).
• Certificate of good standing or activity certificate (apostilled, translated).
• Identification documents for the authorised signatory (as per individual checklist above).
• Power of attorney if the signatory will not appear in person.

Common rejection reasons and fixes

• Name mismatch. The shareholder name in MERSİS differs from the name on the apostilled passport (e.g., middle name omitted). Fix: ensure exact character‑for‑character consistency.
• Expired apostille or notarisation. Some trade registries require apostilled documents to be no older than three to six months. Fix: confirm the local registry’s freshness requirement before filing.
• Incomplete PoA scope. The PoA does not explicitly authorise bank account opening or capital deposit. Fix: use a comprehensive PoA covering all formation acts (see checklist below).
• Capital certificate discrepancy. The deposited amount does not match the subscribed capital stated in the articles. Fix: align the articles and the bank deposit before filing.

Banking, Tax & Post‑Incorporation Compliance (First 90 Days)

Once the trade registry approves the formation and the company is legally established, a series of compliance steps must be completed within the first ninety days to bring the entity into full operational standing.

• Corporate bank account. Convert the capital‑deposit account into an operating account. The bank will conduct full KYC on all beneficial owners holding 25 % or more, expect requests for source‑of‑wealth documentation.
• Tax registrations. The TIN is issued automatically via the One‑Stop Office. The company must also register for VAT if it will conduct taxable supplies (the standard rate of VAT is 20 %; reduced rates of 1 % and 10 % apply to specified goods and services).
• SGK employer registration. If the company will employ staff, registration as an employer with the Social Security Institution must be completed before the first employee’s start date.
• Statutory books and legal records. The trade registry stamps the company’s share‑register, board‑minute book and general‑assembly minute book at formation. These must be maintained in Turkish.
• Monthly and annual filings. Monthly VAT returns, withholding‑tax returns and SGK declarations are standard obligations. Annual corporate‑tax returns are due by the end of the fourth month following the fiscal year‑end.

Engaging a Turkish‑qualified accountant (serbest muhasebeci mali müşavir) before or immediately after incorporation is strongly advisable; the accountant will also act as the company’s e‑declaration signatory for tax filings.

Remote Incorporation Turkey, Power of Attorney Template Checklist & Tips

Remote incorporation via a power of attorney is the most common route for foreign investors who cannot travel to Turkey for the formation. The PoA must be comprehensive enough to cover every action the local representative will perform on the investor’s behalf.

Essential PoA clauses

• Authority to sign the articles of association and any amendments.
• Authority to open a bank account in the company‑in‑formation’s name and to deposit, transfer or block capital.
• Authority to appear before the trade registry and any notary public in Turkey.
• Authority to apply for the company’s tax identification number and to register with SGK.
• Authority to represent the company before the MERSİS system and any governmental authority related to the formation.
• Identification details of both the grantor (investor) and the grantee (Turkish representative), including passport numbers and addresses.

Legalisation and translation requirements

• If the investor’s country is a party to the Hague Apostille Convention, the PoA must be notarised in the home country and apostilled.
• If the country is not a Hague member, consular legalisation through the Turkish embassy or consulate is required.
• In both cases, a certified Turkish translation by a sworn translator must be prepared and notarised in Turkey before use.

A single, well‑drafted PoA covering all formation acts avoids the need to prepare separate instruments for the bank, the trade registry and the tax office, a practice that saves both time and cost in a remote incorporation Turkey scenario.

Common Scenarios & Entity Selection Decision Tree

Choosing the right entity is the first strategic decision in any company formation Turkey 2026 project. The following short decision tree maps common investor profiles to the recommended structure.

• Export HQ or regional sales office. LLC, lower capital, simple governance, one or two shareholders. Sufficient for contract execution, local invoicing and staff employment.
• Tech start‑up seeking VC funding. JSC, share transferability, ability to issue different share classes and accommodate option pools. Meets investor expectations for governance standards.
• Market testing / liaison before committing capital. Liaison office, no commercial activity, no revenue; useful for initial market research, networking and due diligence.
• Holding or IP‑management vehicle. JSC or LLC depending on planned dividend flows and treaty access. Review Turkey’s double‑tax treaty network to optimise withholding rates.

Timeline & Cost Estimate (2026)

Indicative cost ranges

• Trade registry fees & chamber dues: TL 5,000 – TL 15,000 (varies by registered capital and registry district).
• Notary fees (articles, PoA, translations): TL 3,000 – TL 10,000.
• Sworn translation of foreign documents: TL 1,500 – TL 5,000 depending on volume and language pair.
• Legal fees (law firm or corporate services provider): Varies widely, budget USD 2,000 – USD 6,000 for a standard LLC formation with remote incorporation support.
• Bank account opening & first‑year accounting: TL 5,000 – TL 20,000 depending on transaction volume.

Costs fluctuate with exchange‑rate movements, registry‑district tariffs and law‑firm pricing. The ranges above reflect typical market conditions as of early 2026 and should be confirmed with your chosen adviser.
