Foreign ownership is not the hard part. The Foreign Direct Investment Law No. 4875 puts foreign investors on the same footing as Turkish nationals, permits full foreign ownership in most sectors and bars expropriation without compensation. What catches people out is the machinery: capital deposit, notarisation and apostille, signature authority, the tax office, the Turkish-to-foreign staff ratio you need before a work permit is granted. None of it is difficult. All of it punishes an incomplete file.

We act for founders setting up a first limited liability company, for buyers taking over an established Turkish target, and for groups localising through a subsidiary or a branch. The correspondence is in English. The advice is Turkish law.

Choosing your vehicle: LLC vs joint-stock company

The first decision almost every foreign investor faces is structural. The Turkish Commercial Code No. 6102 (TCC) offers two principal capital companies, and the right choice shapes your tax position, your governance and your exit options.

Limited liability company (Limited Şirket)

The LLC is the workhorse of Turkish business. It requires a minimum capital of TRY 50,000, at least one shareholder (individual or corporate, of any nationality) and one director. Liability is limited to the subscribed capital, though a managing partner can bear personal responsibility for unpaid public debts such as taxes and social-security premiums. Share transfers must be notarised and registered, which makes the LLC slightly less nimble for investors who anticipate frequent changes on the cap table.

Joint-stock company (Anonim Şirket)

The JSC suits ventures that plan to raise capital, admit investors or eventually sell. Minimum capital is TRY 250,000, shares transfer by simple endorsement without a notary, and gains on the sale of shares held for more than two years can benefit from favourable tax treatment. The JSC is also the only vehicle that can issue different share classes flexibly and the only one eligible for a public listing. If an exit is realistic, take the JSC and pay the higher setup cost.

Not sure which fits? Two questions usually settle it: will anyone else be putting money in, and do you expect to sell. Converting an LLC into a JSC afterwards is possible. It costs more than choosing correctly on day one, and it takes weeks you will not want to spend.

Company formation for foreigners, step by step

Incorporation runs through the online MERSIS system and the local Trade Registry (Ticaret Sicili). A foreign founder does not need to be physically present: most of our clients grant a remote power of attorney so we can complete the entire process while they remain abroad.

  • Tax numbers & documentation. We obtain Turkish tax numbers for foreign shareholders and directors and prepare notarised or apostilled corporate documents where a corporate shareholder is involved.
  • Articles of association. We draft bespoke articles — not a generic template — setting the purpose, capital, management and signature authority correctly from day one.
  • Registration & capital. We file through MERSIS, register with the Trade Registry, publish in the Trade Registry Gazette and guide the corporate bank account opening and capital deposit.
  • Post-incorporation. We arrange the signature circular, statutory book certification, e-notification and tax-office registration so the company is genuinely operational, not merely registered.

Shareholder agreements and governance

Where a company has more than one owner, the articles of association alone rarely capture the real deal between the parties. A well-drafted shareholder agreement governs board composition, reserved matters requiring a supermajority, drag-along and tag-along rights, pre-emption on new shares, deadlock resolution and exit mechanics. Because Turkish courts read the articles and the shareholder agreement together, we make sure the two documents are consistent and that key protections are, where possible, hard-wired into the articles so they bind the company itself. Most of the shareholder fights we are asked to run in commercial litigation were drafted into existence years earlier, usually by a template.

Foreign direct investment and holding structures

Beyond a single operating company, many investors need a structure: a Turkish subsidiary under a foreign parent, a branch of an overseas company, or a liaison office for market research that cannot trade. Each has distinct tax, liability and reporting consequences. We advise on the most efficient route, on the notification duties owed to the Ministry of Industry and Technology under Law No. 4875, and on double-taxation treaties that may reduce withholding on dividends, interest and royalties flowing out of Türkiye.

Mergers, acquisitions and due diligence

Buy shares in a Turkish company and you buy its unpaid social-security premiums, its ex-employee claims and its tax history with them. Due diligence is how you find those before the price is fixed. We cover corporate records, real estate, employment, litigation, tax and regulatory permits; the choice between a share deal and an asset deal; drafting the share purchase agreement with proper representations, warranties and indemnities; and merger-control notification to the Competition Authority under Law No. 4054 where turnover thresholds are met. We coordinate closely with your tax and financial advisers so the legal terms match the commercial model.

In a share deal you inherit the company's history — its contracts, its tax exposure, its pending claims. Diligence is not a formality; it is how you price that history and protect yourself from it.

Commercial contracts

A Turkish company lives on its contracts, and the Turkish Code of Obligations No. 6098 governs how they are formed, interpreted and enforced. We draft and negotiate the agreements that carry your business — distribution and agency, supply and manufacturing, services, franchising, licensing, non-disclosure and shareholder loans — with careful attention to governing-law and dispute-resolution clauses, currency and penalty provisions, and termination rights. For cross-border deals the arbitration clause matters more than clients expect: draft it loosely and you end up with an award nobody will enforce.

Regulatory and KVKK compliance

The Personal Data Protection Law No. 6698 (KVKK) is modelled on the GDPR and enforced by a regulator that fines. It requires a lawful basis for processing, transparent privacy notices, controlled cross-border data transfers and, for many companies, registration with the data controllers' registry (VERBIS). Non-compliance carries significant administrative fines. Policies, consent flows, data-processing agreements and transfer mechanisms are cheap to build at incorporation. They are expensive to retrofit in the middle of an investor's diligence.

Employing staff and work permits

Hiring in Türkiye means Turkish labour law under the Labour Law No. 4857: written contracts, severance and notice entitlements, working-time rules and social-security registration. Where you bring foreign talent — or where you as the founder need to work in your own company — a work permit is required, and the company must satisfy conditions such as capital and the ratio of Turkish to foreign employees. We handle the employment framework and coordinate the permit process with our immigration team so your people are lawfully in place.

Free zones and incentives

For export-oriented, manufacturing or logistics businesses, Türkiye's free zones under Law No. 3218 can offer corporate-tax and customs advantages, while the general investment incentive regime provides VAT and customs exemptions, tax reductions and social-security support for qualifying projects. We assess whether your activity fits a free-zone or incentive framework and handle the applications, so the structure captures the benefits your business is actually entitled to.

The above is general information, not advice on your matter. Tell us what you want to build, buy or restructure in Türkiye and we will say what the route looks like and where it is likely to stall. WhatsApp, or the contact page. Most clients never come to the office; a power of attorney is enough.

Common Questions

What investors ask before they incorporate

Can a foreigner own 100% of a company in Turkey?

Yes. Under the Foreign Direct Investment Law No. 4875, foreign investors are treated on par with Turkish nationals and may hold 100% of the shares of a Turkish LLC or joint-stock company. No local partner is required in most sectors. A small number of regulated fields — such as broadcasting, maritime cabotage and certain aviation activities — carry ownership caps, which we check before you commit.

Should I set up an LLC or a joint-stock company?

An LLC (Limited Şirket) suits most small and medium businesses: minimum capital TRY 50,000, at least one shareholder, simpler to run. A joint-stock company (Anonim Şirket) needs TRY 250,000, allows share transfers without notarisation, offers favourable tax treatment on share gains after a two-year hold, and is the only vehicle that can list publicly. If you expect outside investment or a future exit, the JSC is usually worth the higher setup cost.

Does forming a company give me residence or citizenship?

Formation alone does not grant status, but it opens pathways. A foreign shareholder or director can apply for a work permit, which also serves as a residence permit. A qualifying capital investment — currently at least USD 500,000 — may make an investor eligible for Turkish citizenship under the relevant regulation. We assess eligibility individually and coordinate with our immigration team.

What ongoing compliance will my Turkish company have?

Turkish companies must keep statutory books, file monthly and annual tax returns, register resolutions with the Trade Registry, hold annual general meetings, and comply with the KVKK data-protection law (including VERBIS registration where applicable). Companies employing foreign staff must maintain valid work permits. The filings are routine. The penalties for missing them are not, and they fall on the company and the director personally.

How long does incorporation take, and must I travel?

With a complete file, registration through MERSIS and the Trade Registry usually takes a few business days once articles, tax numbers and signed documents are ready. Opening the bank account and depositing capital can add time. You generally do not need to travel: most foreign founders appoint us under a remote power of attorney to complete the whole process.

  1. Stage One

    Structure and pre-checks

    Before anything is drafted, the shape of the company is settled: limited şirket or anonim şirket, who holds the shares, who manages, and how signature authority will work. We check whether your sector carries licence requirements or foreign-ownership caps, and run the proposed trade name against the registry so it is not rejected later. A wrong call here is expensive to unwind, so this stage gets real attention.

    Decided at this stage
    Company type — LLC or JSC
    Shareholding & management
    Trade name & sector checks
  2. Stage Two

    Power of attorney and tax numbers

    Most foreign founders never travel for the incorporation. You grant a power of attorney — before a Turkish notary, at a Turkish consulate abroad, or before a local notary with an apostille — and we act on it for every step that follows. In parallel we obtain a Turkish tax number for each foreign shareholder and director. Corporate founders prepare their home-registry documents, apostilled and sworn-translated into Turkish.

    Prepared in parallel
    Notarised power of attorney
    Tax numbers for founders
    Apostilled corporate documents
  3. Stage Three

    Drafting and the MERSİS filing

    We draft the articles of association around your actual deal — capital, share structure, management and representation — rather than pasting a registry template. The incorporation is then entered through MERSİS, the online central registry system, and the appointment with the Trade Registry directorate is booked. Signature declarations of the managers are prepared so the file is complete on the day.

    Key documents
    Articles of association
    Signature declarations
    MERSİS application
  4. Stage Four

    Trade Registry registration

    The company comes into existence at the Trade Registry (Ticaret Sicili Müdürlüğü). The incorporation documents are signed under the power of attorney; for a joint-stock company the bank letter confirming the blocked portion of cash capital is presented. On registration the company acquires legal personality, and the incorporation is announced in the Trade Registry Gazette. With a complete file, this step typically moves quickly.

    What the registry issues
    Registration certificate
    Trade Registry Gazette notice
    MERSİS number
  5. Stage Five

    Tax office, books and notifications

    A registered company is not yet an operating one. The tax office opens the company's tax record and typically sends an officer to verify the registered address (the yoklama visit), so the office lease has to be genuine. The statutory books are certified, the electronic notification address (e-Tebligat) is activated, and where staff will be employed the company is registered with social security. We run this stage so nothing is skipped.

    Registrations completed
    Tax registration & yoklama visit
    Certified statutory books
    e-Tebligat & SGK registration
  6. Stage Six

    Bank account and ongoing compliance

    The corporate bank account is opened and capital paid in; banks apply their own compliance review to foreign-owned companies, so we prepare the ownership documentation they will ask for before they ask. We then set the company's compliance rhythm: the general-assembly calendar, the KVKK and VERBİS position, and work-permit applications where a founder or foreign staff will work in the company.

    KVKK / VERBİS position

Company Formation — Limited Şirket (LLC)

Foreign-founder incorporation file — 10 documents

0 of 10 prepared

  1. The identity document behind every other step — tax number, notary, bank and Trade Registry. A notarised Turkish translation of the identity pages is required for the notary and registry stages.

    Where to obtain

    Notarised translation from any sworn translator; we arrange same-day notarisation near our office in Kağıthane.

  2. A potential tax number (vergi kimlik numarası) is needed for each foreign shareholder and director before the notary, capital and registry steps can proceed.

    Where to obtain

    Any tax office (vergi dairesi) with your passport, or online through the Interactive Tax Office (İnteraktif Vergi Dairesi).

  3. Authorises us to complete the MERSİS filing, notary work, tax registration and the Trade Registry appointment while you remain abroad. The wording must expressly cover company formation — we provide the exact text.

    Where to obtain

    A Turkish notary, the nearest Turkish consulate, or a foreign notary with apostille and sworn Turkish translation.

  4. The company's constitutional document (şirket sözleşmesi) — trade name, registered seat, purpose, capital, shares and management — drafted around your actual deal, not a registry template.

    Where to obtain

    Drafted by us and filed electronically through MERSİS ahead of the Trade Registry appointment.

  5. Where the founder is a company rather than an individual: a current registry extract or certificate of activity, plus a resolution of the competent organ to incorporate the Turkish company and appoint a representative.

    Where to obtain

    Your home trade registry or companies house, apostilled in the issuing state, then sworn-translated into Turkish and notarised.

  6. Every Turkish company must have a registered address. The lease or title deed goes into the incorporation file and is checked when the tax office verifies the address after registration — so the address has to be genuine.

    Where to obtain

    Your landlord or a serviced-office provider; we review the lease before you sign it.

  7. Specimen signatures (imza beyannamesi) of the persons authorised to represent the company, given under the company's trade name — the basis on which banks and authorities verify who may bind the company.

    Where to obtain

    Prepared at the Trade Registry directorate at incorporation; abroad, at a Turkish consulate.

  8. For a joint-stock company, a bank letter confirming that the statutory portion of the subscribed cash capital has been deposited and blocked before registration. An LLC's capital may be paid in after incorporation within the statutory period.

    Where to obtain

    The Turkish bank where the company's capital account is opened; the blocked amount is released to the company after registration.

  9. A chart and supporting extracts identifying the individuals who ultimately own or control a corporate founder. Banks ask for it at account opening, and the tax administration requires beneficial-ownership notification after incorporation.

    Where to obtain

    Assembled from home-registry extracts and group records; we put it into the format Turkish banks and authorities expect.

  10. The bank's compliance file for a foreign-owned company: registry certificate (sicil tasdiknamesi), tax record, evidence of signature authority and shareholder identification. Banks review foreign ownership carefully, so a prepared file saves repeated visits.

    Where to obtain

    Registry certificate from the Trade Registry, tax record via the Interactive Tax Office; we assemble the set for the bank.
