Short answer: A foreign-owned company registered in Turkey can open a corporate bank account, but the bank will not open it on incorporation papers alone. Expect to provide the company’s registry and tax documents, signature circulars, passports and Turkish tax numbers of shareholders and directors, beneficial-owner details, and a clear explanation of what the company will do and how money will flow through the account. With a complete and consistent file, foreign-owned companies usually get an account within a few business days. With gaps or contradictions, the process can take weeks or end in rejection.

This article explains which documents Turkish banks ask for in 2026, the order in which the process runs, and the most common reasons applications from foreign entrepreneurs get stuck. It is written for entrepreneurs who live outside Turkey and plan to trade through a company they set up in Turkey.

Why do banks look more closely at foreign-owned companies?

Turkish banks operate under Law No. 5549 on the Prevention of Laundering Proceeds of Crime, supervised by the Financial Crimes Investigation Board (MASAK). Under this framework, a bank must know who ultimately owns and controls a company, not just who appears in the share register. If a foreign company or a chain of holding companies sits above the Turkish entity, the bank has to look through every layer to reach the natural persons at the top.

This is why registration in the Trade Registry does not by itself guarantee an account. Each bank makes its own risk decision. Even banks’ own published checklists state that submitting the listed documents does not guarantee an account (İşbank). In practice, the bank is looking for answers to three questions:

• Who is behind the company? Shareholders, directors, authorised signatories and ultimate beneficial owners.
• Is the company what it appears to be? Registry records, tax registration, office address and articles of association that are consistent with each other.
• Will the account activity make sense? Expected customers, suppliers, countries, currencies and monthly volumes.

A file that answers all three clearly is usually concluded quickly. A file that leaves any of them vague leads to follow-up questions and requests for more documents.

What must be in place before you apply?

There are two different accounts in the process, and entrepreneurs often confuse them.

1. The capital deposit account (before registration). During incorporation, the founders open an account in the name of the company to be formed and deposit the portion of share capital that the law requires to be paid before registration, depending on company type. The bank’s deposit letter goes into the Trade Registry file. To open this account, every non-Turkish shareholder and board member must obtain a potential tax identity number from a tax office (Invest in Türkiye). This number can also be obtained through a proxy holding a suitable power of attorney.

2. The operating account (after registration). Once registered, the company receives its own tax number. The capital account is converted into an operating account, or a new operating account is opened. The full know-your-customer (KYC) review takes place at this stage. Having deposited the capital does not mean the bank will open the operating account with all services.

Before applying for the operating account, make sure the following are in place:

• The company registered in the Trade Registry, with the registration published in the Turkish Trade Registry Gazette
• The company’s tax number and tax registration certificate
• A business address registered in the company’s name through a lease or title deed
• Notarised signature circulars for everyone who will have signing authority on the account
• Turkish tax numbers for all foreign shareholders, directors and signatories

Documents banks ask for: a checklist

The list varies from bank to bank, but a foreign-owned company resident in Turkey is usually asked for the documents below. For one bank’s published list, see İşbank’s page for foreign-capital companies.

Documents issued abroad: Documents issued in another country must first receive an apostille in that country (or Turkish consular legalisation for countries outside the Hague Convention), then be translated into Turkish and certified by a Turkish notary (İşbank). Because this can take several weeks, start it at the very beginning of your formation plan.

Step-by-step process and timeline

The order matters. A bank will not open any account without a tax number, so the process starts there.

1. Prepare your foreign documents. Passport copies, corporate shareholder records if any, and the power of attorney are apostilled, translated and notarised.
2. Obtain potential tax numbers. These are issued by the tax office for foreign shareholders and board members. A proxy can do this for you.
3. Open the capital account and deposit the capital. The bank issues the deposit letter that goes into the Trade Registry file.
4. Register the company. Registration is done through MERSİS and announced in the Trade Registry Gazette. The company receives its tax number.
5. Prepare the KYC file for the operating account. The checklist above, the ownership chart and the activity description are combined into a single file.
6. Attend the bank meeting. Confirm with the bank in advance whether signatories must attend in person or can be represented by power of attorney. Some banks can onboard customers remotely by video call in certain cases.
7. Answer follow-up questions and activate the account. Internet banking, foreign-currency accounts and authority levels are set up at this stage.

How long does it take? With a complete file, opening an account often takes 1–3 business days (Özbek CPA). For foreign-owned companies it usually takes a few days longer (Property Turkey). Most of the lost time is usually not at the bank but in the apostille and translation stage for foreign documents.

Why are applications rejected or delayed?

A rejection does not mean the company cannot open an account in Turkey. Most of the time the problem lies in the file and can be fixed (Global Law Experts). The most common reasons are:

• Inconsistencies between documents. The name spelled one way in the passport and another way in the translation, registry or tax record. It looks minor but can hold a file for weeks.
• Unclear beneficial ownership. In multi-layered structures, not every layer up to the ultimate owner is documented.
• A vague description of activity. General statements such as “we will do international trade”. The bank wants to see which products, which countries, which currencies and what volume.
• Unexplained source of funds. No documentation of where the capital and first transactions come from.
• Foreign documents not properly certified. Papers without apostille, translation or notarisation.
• Links to high-risk countries or sectors. For some nationalities, countries and sectors, banks carry out a more extensive review and ask for more documents. In that case the file needs to be prepared in more detail from the start.
• Authority issues. Unclear signing authority, or an unclear scope or validity period of a power of attorney.

Practical tips

• Prepare one consistent file. Keep all documents, translations and apostilles in one folder with a dated index. The company name, activity description and shareholding percentages must be the same in every document.
• Check name spellings at the very start. The Latin spelling in the passport must match exactly in the tax record, the registry and the translations. Mistakes are common with names transliterated from Cyrillic or Arabic script.
• Write a short activity and payment-flow summary. On a single page, state your main suppliers, customer markets, currencies and estimated monthly volume. It answers most of the bank’s questions up front.
• Separate personal and company documents. Present the shareholder’s personal source-of-funds documents and the company’s commercial documents under separate headings.
• Agree in advance who will attend the meeting. If a signatory cannot travel to Turkey, confirm beforehand that the power of attorney is drafted in a form the bank will accept.
• Consider more than one bank. Banks differ in risk appetite and policies toward foreign customers. A rejection by one bank does not mean another will reject you too.

The accountant’s role in this process

The decision to open an account belongs entirely to the bank, and no adviser can guarantee it. A Turkish certified public accountant (SMMM) does, however, play an important role in making sure the file reaches the bank complete and consistent: obtaining potential tax numbers, completing the company’s tax registration, preparing the beneficial ownership notification, aligning the activity and payment-flow summary with the accounting records, and keeping the financial documents the bank will later ask for in order. After the account is opened, keeping account activity consistent with the company’s declared business is also essential for a healthy relationship with the bank.

Frequently asked questions

Does a foreign-owned company need a Turkish shareholder to open an account?

No. There is no general local-shareholder requirement for foreign-owned companies to open an account. The bank evaluates the company and the people involved by its own criteria.

Is a passport alone enough?

No. A passport only identifies the person. A company account also requires documents showing that the company exists, who can represent it, its ownership structure and its planned activity.

Can the account be opened without coming to Turkey?

It depends on the bank and the case. Much of the incorporation work can be done through a power of attorney. For the operating account, some banks require the signatory to attend in person, while others accept a power of attorney or onboard by video call. Confirm with the chosen bank before applying.

Does an open capital account guarantee that the operating account will be opened?

No. The capital account and the KYC review for the operating account are related but separate processes. The bank may ask for more information before activating commercial services.

Is beneficial ownership reported only to the bank?

No. Apart from the bank’s own review, corporate taxpayers in Turkey must also report their beneficial owners to the Revenue Administration (Erdem & Erdem). The two declarations need to be consistent.

What should I do if the account is rejected?

First, try to understand the reason from the bank. You can complete the missing or inconsistent documents and reapply to the same bank, or go to a different bank with a stronger file.
