Foreign individuals and foreign companies can establish a Turkish company in Istanbul under the same general company-law framework that applies to domestic investors. The decisive work starts before the registry filing: choosing the legal form, legalizing foreign documents, defining management authority, mapping tax and VAT, and separating share ownership from immigration and work-permit questions.

Short Answer

A foreign founder may establish a limited liability company or joint stock company in Istanbul without adding a Turkish shareholder solely because of nationality. The incorporation file normally requires a potential tax number, MERSIS articles, a registered address, translated and notarized identity or corporate documents, trade registry filings and post-registration tax activation. A power of attorney can cover many steps, but personal presence may still be requested for banking, signatures, identity checks or a particular registry process.

Short Summary

The cleanest Istanbul formation process has four document tracks: shareholder identity, management authority, registered office and operating tax model. Foreign documents issued abroad may need apostille or Turkish consular legalization, followed by notarized Turkish translation. After registration, the company must complete tax, accounting, invoicing, payroll and beneficial-owner obligations before normal operations begin.

Practical Answer

Company registration is not the same as being ready to trade. A company may appear in the trade registry while its banking, tax inspection, invoice process, payroll, foreign-service purchases and client contracts are still incomplete. The formation plan should therefore continue through the first invoice and the first monthly filing cycle.

Start With a Formation File Review

Prepare these facts before drafting the articles:

• Nationality and residence of each individual shareholder
• Country and legal form of each corporate shareholder
• Proposed activity and NACE scope
• Istanbul registered-address plan
• Share percentages and capital commitments
• Manager or board-member structure
• Who will sign contracts and operate bank accounts
• Whether any foreign shareholder will physically work in Türkiye
• Client countries, local sales and expected invoice types
• Employee, contractor and payroll plan
• Foreign software, consulting, royalty or management payments
• Whether incorporation will be followed by power of attorney

First Decision Table

Foreign Individual Shareholder Documents

The Istanbul Chamber of Commerce lists the following core items for a foreign individual shareholder in a limited company file:

• Passport copy translated into Turkish and notarized
• Turkish tax identification number or foreigner identification number
• Notarized residence permit if the person resides in Türkiye
• MERSIS articles and formation application
• Signature declaration where required
• Power of attorney if the filing or signing is handled by proxy

The passport spelling, tax number, MERSIS record and power of attorney must use consistent names. Differences in middle names, transliteration or address can delay registration or banking.

Foreign Corporate Shareholder Documents

A foreign legal entity shareholder generally needs a current document showing its registration, status and authorized signatories, together with the competent corporate resolution approving the Turkish investment.

Documents executed abroad normally need apostille under the Hague Convention or legalization by the relevant Turkish consulate, followed by official Turkish translation and notarization. The exact route depends on the issuing country and document.

LLC, JSC, Branch or Liaison Office?

The correct form depends on liability, investors, profit distribution, transfer pricing, sector licenses and exit plans. A regulated activity may require a specific company form or authorization beyond ordinary registry incorporation.

Istanbul Registration Sequence

1. Define activity, legal form, shareholders and management.
2. Obtain potential tax numbers for foreign founders and relevant representatives.
3. Secure and document the registered address.
4. Prepare the articles through MERSIS.
5. Complete apostille/legalization and Turkish translation of foreign documents.
6. Sign the articles at the registry or proceed under a valid power of attorney.
7. File with the Istanbul Trade Registry and Chamber of Commerce.
8. Complete tax registration and workplace verification.
9. Open statutory books and accounting records.
10. Arrange corporate banking and signing authority.
11. Configure invoice and e-document obligations where applicable.
12. Register payroll and social security before hiring employees.

Each stage depends on the previous record. Drafting the activity too narrowly, using an incomplete power of attorney or leaving foreign names inconsistent often creates avoidable rework.

Can the Company Be Formed Remotely?

Many registry and tax steps can be followed by an authorized representative under a properly drafted power of attorney. Istanbul Trade Registry guidance states that founders do not need to attend solely to sign the articles where a valid original or notarized power of attorney is submitted.

Remote formation should not be promised as a universal, zero-visit process. A bank, registry unit, notary or compliance team may request personal presence, additional identity verification or original documents. The power of attorney should expressly cover the intended registry, tax, address and signature actions rather than using generic wording.

Registered Address and Tax Activation

The company needs a documented legal address suitable for its actual activity. Service businesses may use an office arrangement that satisfies registry, lease and tax-verification requirements, but regulated, retail, storage, manufacturing or licensed activities can require a specific physical workplace.

Before selecting the address, check:

• Whether the activity is permitted at the property
• Lease and landlord information
• Tax-office verification requirements
• Municipality or workplace-license needs
• Storage, customer access or employee use
• Whether the address appears consistently in MERSIS, lease and tax records

Shareholder Status Is Not a Work Permit

Owning shares and physically working in Türkiye are separate legal questions. A foreign person may invest in a Turkish company under the foreign-investment framework, but active work or management performed in Türkiye can require a work permit.

For company-partner work-permit applications, the Ministry of Labour's criteria effective from 3 August 2026 include financial, shareholding and employment tests. The published criteria refer to at least TRY 500,000 attributable to the foreign partner, total paid-in capital of at least TRY 500,000, at least a 20% share, and employment of five Turkish citizens from the beginning of the seventh month for the initial permit. Exceptions and activity-specific rules can change the result, so the work-permit file should be reviewed separately from incorporation.

Tax Questions Before the First Invoice

• Will the company sell in Türkiye, abroad or both?
• Is the income a service, SaaS subscription, license, commission or goods sale?
• Does Turkish VAT apply, or can a documented service-export exemption apply?
• Can a qualifying service-export profit deduction apply?
• Will the company pay royalties, management fees or foreign software subscriptions?
• Are reverse-charge VAT and withholding relevant to foreign purchases?
• Will a foreign related party invoice the Turkish company?
• How will transfer pricing and service evidence be maintained?
• Will dividends be distributed to foreign shareholders?
• Does a tax treaty affect withholding or residence analysis?

Foreign ownership does not create a general tax exemption. The Turkish company is a Turkish taxpayer and must classify each revenue and expense under Turkish rules.

Post-Incorporation Compliance File

Common Mistakes

• Treating registry completion as the end of setup
• Using inconsistent passport names across documents
• Preparing a power of attorney that omits tax or signature powers
• Choosing a generic activity that does not match actual revenue
• Assuming a foreign shareholder may work in Türkiye without a separate permit review
• Promising that every banking step can be completed remotely
• Starting invoices before tax and accounting records are ready
• Mixing local and foreign revenue without a VAT map
• Ignoring withholding and reverse-charge VAT on foreign payments
• Using a registered address unsuitable for the activity

Frequently Asked Questions

Is a Turkish shareholder required?

Not solely because the founders are foreign. Türkiye's foreign-investment framework is based on equal treatment, subject to special rules for regulated sectors.

Must the foreign founder live in Türkiye?

Residence is not a general condition for share ownership. Residence, physical work, management activity and work permission must nevertheless be reviewed separately.

Can a power of attorney be used?

Yes, many steps can be handled by proxy where the authority is drafted correctly and the foreign document is properly legalized and translated. Banking and some identity or signature steps may still require the founder.

Does incorporation automatically create a work permit?

No. Company registration, share ownership, residence and work authorization are separate processes.

Can the company invoice foreign clients without VAT?

Not automatically. The customer location, service, place of use, contract and supporting evidence must satisfy the service-export VAT conditions.

What should be sent for the first review?

Send shareholder passports or corporate registry documents, residence countries, proposed activity, share and management structure, address plan, work-permit need, client countries, banking expectations and power-of-attorney preference.
