Quick answer: Company registration in Türkiye is built around a consistent incorporation file: shareholder identity and authority, registered address, company purpose, capital, management/representation rules and the MERSİS application must all tell the same story. For foreign founders, the difficult part is usually not eligibility; it is preparing foreign documents and Turkish filing data so they match across every stage.
This guide explains the MERSİS and Trade Registry filing mechanics: how the complete incorporation file moves from consistent founder/address/capital/authority data into registry submission. For a deeper explanation of the MERSİS system itself—including the MERSİS number, access methods, data fields and data-quality controls—use MERSİS Company Registration in Turkey: System Guide. For the broad end-to-end formation guide, use Company Formation in Turkey: Complete 2026 Guide for Foreigners. For timing, use the separate company formation timeline guide.
A strong registration file starts with ownership, authority, address and activity decisions before the MERSİS application is finalised.
What MERSİS Does in Company Registration
The Ministry of Trade describes MERSİS as the central electronic system used for company and commercial-enterprise registration, amendment and deregistration processes. Company establishment data are prepared electronically and then processed through the relevant Trade Registry workflow.
MERSİS is not simply a form-filling website. The data entered there become the backbone of the incorporation file: company name, shareholders, capital, headquarters address, purpose/activity and management/representation rules must align with the supporting records submitted for registration.
| MERSİS data |
What must match it |
| Founder/shareholder identity |
Passport, tax-number data, corporate-shareholder records and translations |
| Company address |
Address record and right-to-use documentation |
| Capital and ownership |
Articles of association and shareholder commitments |
| Management/representation |
Articles, appointments, powers of attorney and signature formalities |
| Company purpose/activity |
Articles and the actual business model, including sector-specific needs |
Foreign Founders Can Own Turkish Companies
Current official investment guidance states that there is generally no nationality restriction on shareholders or management rights, subject to sector-specific exceptions. A Turkish partner is therefore not a general requirement merely because the founder is foreign.
Foreign founders most commonly use an LLC or JSC, while overseas companies may also compare a Turkish subsidiary or branch. Structure choice should be made before the filing data are drafted because capital, governance and document requirements differ.
For that decision, see Types of Companies in Turkey.
Current Minimum Capital Rules
Current Ministry of Trade guidance sets the statutory minimum capital at TRY 50,000 for a limited liability company and TRY 250,000 for a joint-stock company. For a JSC, at least 25% of cash capital is generally paid before registration and the balance within 24 months. For an LLC, subscribed capital may generally be paid within 24 months after registration.
Share capital is company money committed by the shareholders. It is not a Workon service fee or a Trade Registry fee.
Step 1: Build the Founder and Authority File
The individual-founder file and foreign-corporate-shareholder file are different.
| Founder type |
Main proof questions |
| Foreign individual |
Who is the person, what identity/tax data will be used, and who may act under a power of attorney if formation is remote? |
| Foreign company shareholder |
Does the parent exist and remain active, who can bind it, who approved the Turkish investment, and who is authorised to represent it? |
Do not legalise documents simply because they look relevant. First determine which home-country record proves each Turkish filing requirement. The legalisation route then depends on the issuing jurisdiction and document type.
Step 2: Lock the Registered Address Before Final Filing
The company needs a Turkish registered address. The address should be finalised early because it appears in the official company record and must be supported by the appropriate right-to-use documentation.
A virtual office may be suitable for many businesses, but suitability depends on the activity, premises requirements and actual arrangement. Registration acceptance, tax-office procedures and sector-specific premises requirements are separate questions.
For the address decision, use Registered Business Address in Turkey.
Step 3: Draft the Articles Around the Real Operating Model
The articles of association should reflect the company that will actually operate, not merely a generic template. Key items include:
- company title;
- headquarters address;
- business purpose and activity scope;
- capital and share ownership;
- manager/director appointments and representation rules;
- any special governance provisions required by the founders.
Overly narrow drafting can create later amendment work; overly broad or inaccurate drafting can create licensing, banking or operational confusion. The correct level depends on the real business model.
Step 4: Check Identity and Name Consistency
Foreign-founder files are especially sensitive to inconsistent identity data. Passport spelling, transliteration, tax-number data, corporate records, translations and MERSİS entries should be checked as one dataset.
Common failure pattern: the correct person or company appears in every document, but the name is written differently across records. That can trigger correction work even though the underlying identity is obvious to the founder.
Step 5: Prepare Powers of Attorney and Representation Carefully
Remote incorporation can often be coordinated through a properly drafted power of attorney. The document must grant the authority actually required for the intended filing. A vague or narrow PoA can create an additional notarisation/legalisation cycle.
Remote company registration does not automatically make every post-registration process remote. Banking and other institution-controlled procedures have separate identification and approval rules.
See Power of Attorney Turkey Guide.
Step 6: Submit the Trade Registry File
Once the MERSİS application and supporting documents are ready, the relevant Trade Registry reviews the incorporation file and completes registration when the requirements are satisfied. Registration and the associated announcement then become part of the official commercial-registry record.
The registry stage should not be mixed with bank-account activation, tax-office verification or work-permit timing. Those may follow or run in parallel, but they are controlled by different institutions.

| Who can bind it? |
Management/representation clauses, appointments and signature documents |
| Where is it registered? |
MERSİS, articles and address documentation |

Articles and capital documentation |
| Who may complete the filing? |
Founder authority or power of attorney |
Registration Is Not Operational Readiness
A legally registered company may still need several operating steps before it can function as intended. Depending on the case, these can include:
- licensed CPA/tax onboarding;
- tax-office commencement procedures and address verification;
- corporate bank-account application;
- KEP, e-signature, financial seal or e-invoicing steps where applicable;
- SGK employer/workplace procedures when employees or the operating model require them;
- work permits for foreign personnel where required;
- municipal or sector-specific licences.

Banking Must Be Planned Separately
A Trade Registry certificate does not guarantee a corporate bank account. Banks conduct their own KYC and risk assessment covering ownership, controllers, business activity, expected transactions and source-of-funds information.
Many banks may require an authorised director or signatory to attend in person. A bank-specific remote route can sometimes be coordinated, but eligibility, approval and activation remain with the bank.

Registration Mistakes Worth Preventing
- Legalising the wrong foreign record: confirm what the Turkish file must prove before ordering documents.
- Using inconsistent identity data: cross-check passport, tax-number, translation and MERSİS spelling.
- Finalising the address too late: resolve right-to-use and activity suitability before filing.
- Using a PoA that does not cover the required acts: map the filing sequence before signature.
- Treating MERSİS as separate from the documents: every core data point should match the supporting file.
- Assuming registration equals launch: plan banking, tax/CPA and operational requirements separately.

Frequently Asked Questions
The shareholder and signatory identities, company title, registered address, capital, activity\/purpose and management\/representation rules should be consistent across MERSİS and the supporting incorporation documents. Foreign records and Turkish translations should describe the same people, entities and authorities.
No. MERSİS is the electronic filing and data-preparation layer. Legal incorporation is completed only after the competent Trade Registry reviews and accepts the filing and registers the company.
Common problems include inconsistent names or passport data, incomplete corporate authority evidence, a resolution that does not cover the Turkish investment, insufficient power-of-attorney wording, mismatched translations and documents prepared through the wrong authentication route.
Use one approved official address consistently across the MERSİS entry and supporting right-to-use documents. The address model should also be compatible with the company’s real activity and any premises-specific requirements.
The Registry reviews the incorporation file under the applicable company and registry rules, including the articles, founder\/shareholder information, capital, representation, address and supporting authority documents. MERSİS data alone do not replace that legal review.
Correct the underlying source of the inconsistency rather than patching one field in isolation. Reconcile the MERSİS data, articles, translations, powers of attorney and other supporting documents so the revised filing remains internally consistent.
