Opening a Bank Account in Turkey as a Foreigner: KYC, Passport, Tax Number, Address and Source of Funds

1. Applying for an account is different from having an unconditional right to acceptance

Turkish banks are private or public financial institutions operating under banking and AML legislation. A foreign person may approach a bank and request an account, but account opening is also a contractual relationship and the bank must complete its customer-acceptance controls.

A bank can refuse a relationship where identity cannot be verified, requested documentation is not supplied, sanctions/AML risk is unacceptable, the stated purpose is inconsistent with the profile or the bank’s internal risk policy does not permit the relationship.

Applicants should therefore treat online lists saying “these three documents guarantee an account” as unreliable.

2. Law No. 5549 requires customer identification and other customer-due-diligence measures

The anti-money-laundering framework requires obliged institutions to identify customers and take additional measures within the customer-due-diligence system. Banks must know with whom they are establishing a relationship and assess unusual or high-risk transactions.

KYC is not limited to copying a passport. The bank may need to understand who controls the funds, why the account is needed, expected transaction volumes, countries involved and whether a company or another person is the true beneficial owner.

Risk-based review can become more detailed for high-value international transfers, politically exposed persons, complex corporate structures and higher-risk jurisdictions.

3. The passport should be valid and consistent with every other record

A foreign passport is commonly the primary identity document. The bank will compare name, surname, birth date, nationality and document number with Turkish tax and immigration data where available.

Transliteration differences can create problems. A Russian, Arabic or Chinese name can appear differently in Latin characters across passport, tax number, title deed and company records.

If the applicant recently renewed the passport, carrying the old passport or official linking document can help the bank reconcile existing records.

4. A Turkish potential tax identification number is an identifier, not account approval

The Revenue Administration provides a digital potential-tax-number service for foreigners. The number can be used by banks and other institutions to identify the foreign person in Turkish administrative systems.

Our Turkish tax identification number guide explains that process.

Obtaining the number does not create Turkish tax residence and does not oblige a bank to open an account.

5. A foreigner identity number can simplify domestic identity matching

Foreigners with qualifying Turkish immigration status can have an 11-digit foreigner identity number. Banks can use that number to match Turkish public records.

A person applying from abroad before obtaining Turkish residence can still have banking needs, but the bank’s document set may be different.

The applicant should not use another person’s Turkish identity or address merely to satisfy an online form.

6. Address evidence is a core part of customer identification

Banks commonly request a current residential address and documentary proof. Acceptable evidence can depend on the bank and whether the address is in Türkiye or abroad.

Utility invoices, official residence certificates, government records, tenancy documents or bank statements can be relevant. A short hotel reservation can be inadequate for a relationship expected to continue indefinitely.

The address given to the bank should remain consistent with tax-residence self-certification and other KYC information.

7. Source of funds becomes especially important for large transfers

A customer sending significant funds to Türkiye should expect questions about where the money came from. Legitimate sources include salary savings, property sale proceeds, dividends, inheritance, business income or investment liquidation, but they should be documented.

A property-sale contract, bank history, probate document, dividend statement or audited company record can prove origin of funds.

“This is my money” is not a substitute for documentary source-of-funds evidence where the bank is legally required to understand the transaction.

8. The expected use of the account should match the customer profile

A person opening a simple account for household expenses presents a different profile from an investor expecting million-dollar property transfers or a company collecting international trade payments.

The bank can ask expected monthly turnover, counterparties, currencies and countries.

Unexpected activity after opening can trigger a renewed compliance review.

9. Remote onboarding is possible only within the bank’s technical and legal framework

Turkish banking rules permit remote customer identification in defined circumstances, but not every bank offers every foreign customer a fully remote account-opening path.

Video identification, NFC passport reading, Turkish phone requirements or system-supported identity types can determine whether onboarding works.

A foreign customer who cannot complete remote verification may be asked to appear at a branch.

10. A power of attorney can assist, but banks can still require personal KYC

A properly prepared power of attorney can authorise a representative to perform banking transactions where the bank accepts representation and the power contains sufficient authority.

However, AML rules require the bank to identify the customer and also identify the representative. A power of attorney does not allow anonymity.

Some banks can require personal appearance for account establishment or specific high-risk services even where representation is legally possible.

11. A foreign company account requires corporate and beneficial-owner documents

A foreign legal entity opening a Turkish account can be asked for incorporation documents, registry extract, articles, tax information, authorised signatory resolution, ownership chart and ultimate beneficial-owner information.

Foreign corporate documents may require apostille/legalisation and Turkish translation.

The bank must understand who ultimately controls the entity rather than identifying only the company name.

12. Property buyers should open the banking structure before the title date

Foreign buyers often need a Turkish bank account for purchase payments, taxes, utilities or citizenship-related foreign-currency procedures.

The account should be operational before the scheduled title transfer. A compliance hold on a large first transfer can delay closing.

Our foreign property-buyer guide covers title due diligence separately.

13. Citizenship-investment banking must follow the specific investment route

A person relying on the USD 500,000 bank-deposit citizenship route needs much more than a normal account. The deposit must satisfy the exceptional-citizenship rules and the required three-year restriction/BDDK conformity process.

Our bank-deposit citizenship guide addresses that route.

An ordinary current account should not be described as a citizenship investment account.

14. CRS and FATCA tax-residence classification is separate from Turkish residence permission

Banks collect tax-residence/self-certification information for international financial-account reporting. A customer can live in Türkiye under a residence permit yet remain treaty tax resident elsewhere for a period, or become Turkish tax resident without changing nationality.

False tax-residence declarations can create reporting and compliance problems.

The customer should identify all relevant tax jurisdictions and taxpayer numbers accurately.

15. A bank’s refusal should be distinguished from unlawful discrimination or an administrative freeze

A commercial decision not to establish a customer relationship can differ from an existing-account restriction ordered by law or imposed during compliance review.

If a bank gives a written reason, the customer should identify whether the issue is missing KYC, sanctions screening, address, source of funds, tax reporting or another matter.

A complaint route depends on the nature of the bank and transaction; not every refusal becomes a court case.

16. Existing accounts can be restricted during legal or compliance review

An account can be affected by judicial seizure, enforcement attachment, tax collection measures, MASAK-related processes or a bank’s internal compliance review. Those legal bases are different.

The customer should obtain the available notice or bank explanation and identify the authority behind the restriction.

Sending more transfers into a restricted account before understanding the reason can complicate the position.

17. Prepare the KYC file before transferring money

A practical file can include passport, Turkish tax number, foreign/Turkish address proof, residence card/YKN if available, employment/business information, bank statements, source-of-funds documents, tax-residence certificate and transaction-purpose documents.

For companies, add corporate registry, articles, board/signatory authority and beneficial-owner chart.

Conclusion

A foreign customer should approach Turkish banking as a KYC and transaction-planning exercise, not a three-document guarantee. Identity, address, source of funds, tax residence and beneficial ownership must be consistent, and each bank can lawfully apply its own risk-acceptance framework.
