Transfer Pricing in Turkey 2026: Rules, Documentation & Compliance for Multinational Companies

Transfer pricing is one of the most critical compliance areas for multinational companies operating in Turkey. The Turkish Revenue Administration has aligned its transfer pricing regulations with OECD guidelines, and enforcement has intensified significantly in recent years. This guide explains the transfer pricing framework in Turkey for 2026, including documentation requirements, penalties, and best practices.

What is Transfer Pricing?

Transfer pricing refers to the pricing of transactions between related parties - such as a Turkish subsidiary and its foreign parent company. Turkish tax law requires that these transactions be conducted at arm’s length prices - meaning the prices must be comparable to what independent parties would agree to in similar circumstances. If transfer prices are not at arm’s length, the Revenue Administration can adjust the taxable income, resulting in additional tax liabilities and penalties.

Turkish Transfer Pricing Regulations

Transfer pricing in Turkey is primarily governed by Article 13 of the Corporate Tax Law (Law No. 5520) and detailed in the Transfer Pricing General Communiqué. The regulations follow OECD Transfer Pricing Guidelines and cover:

• Definition of related parties (shareholders with 10%+ ownership, group companies, companies sharing common management)

• Arm’s length principle and acceptable transfer pricing methods

• Documentation and reporting requirements

• Advance Pricing Agreements (APAs)

• Corresponding adjustments and mutual agreement procedures under double taxation agreements

Accepted Transfer Pricing Methods

Turkey accepts five transfer pricing methods, consistent with OECD guidelines:

• Comparable Uncontrolled Price (CUP): Most preferred method; compares prices in controlled transactions to comparable uncontrolled transactions

• Cost Plus Method: Adds an appropriate markup to the cost of goods or services

• Resale Price Method: Subtracts an appropriate margin from the resale price to a third party

• Transactional Net Margin Method (TNMM): Compares the net profit margin of the controlled transaction to comparable independent transactions

• Profit Split Method: Splits the combined profit from a controlled transaction based on the relative contributions of each party

Documentation Requirements

Turkish transfer pricing documentation follows a three-tier structure aligned with the OECD BEPS Action 13:

• Master File (Ana Dosya): Required for companies that are part of a multinational group. Contains organizational structure, group business overview, intangibles, intercompany financial activities, and group financial and tax positions

• Local File (Yerel Dosya): Required for all companies with related-party transactions. Contains detailed information about the Turkish entity’s transactions, functional analysis, transfer pricing methods applied, and comparability analysis

• Country-by-Country Report (CbCR / Ülke Bazlı Raporlama): Required for multinational groups with consolidated revenue exceeding 750 million EUR. Filed by the Turkish entity or received from the parent through exchange of information agreements

Annual Transfer Pricing Form

All corporate taxpayers with related-party transactions must file the Annual Transfer Pricing Form together with their corporate tax return. This form discloses the nature and volume of related-party transactions, the methods used, and whether documentation has been prepared. Late or incomplete filing carries significant penalties.

Penalties for Non-Compliance

Transfer pricing non-compliance in Turkey can result in:

• Income adjustment: The Revenue Administration can re-characterize transactions at arm’s length prices, increasing taxable income

• Tax loss penalty: One-time penalty equal to the underpaid tax

• Default interest: Monthly interest accruing from the original due date

• Deemed dividend distribution: If the transfer pricing adjustment results in a deemed profit distribution to a foreign related party, withholding tax may also apply

Frequently Asked Questions

Which companies must prepare transfer pricing documentation in Turkey?

Any company with related-party transactions must prepare a Local File. Businesses that belong to a multinational group also need a Master File, and groups with consolidated revenue above EUR 750 million fall under Country-by-Country Reporting. The trigger is the existence of related-party transactions, not company size, so even small intercompany dealings can create an obligation.

Who counts as a related party under Turkish rules?

Article 13 of the Corporate Tax Law treats shareholders holding 10% or more, group companies, and entities under common management or control as related parties. Transactions with any of them must meet the arm’s length standard.

What does the arm’s length principle mean in practice?

It means the price agreed between related parties should match what unrelated parties would agree to under comparable conditions. You support this with one of the five accepted methods, most often the Comparable Uncontrolled Price or the Transactional Net Margin Method, backed by a benchmarking study.

When is the Annual Transfer Pricing Form filed?

It is submitted together with the corporate tax return by the end of April. The form discloses the type and volume of related-party transactions and confirms whether documentation has been prepared, so the underlying file should already be in place before filing.

What are the penalties for weak documentation?

If the Revenue Administration adjusts your prices, the additional income is taxed and a tax loss penalty equal to the underpaid tax may apply, together with monthly default interest. Where the adjustment is treated as a hidden profit distribution to a foreign related party, dividend withholding tax under applicable treaties can also be charged.

Can we agree pricing with the tax authority in advance?

Yes. An Advance Pricing Agreement lets you confirm a transfer pricing method with the Revenue Administration before transactions take place, which reduces the risk of a later adjustment. It is most useful for high-value or recurring intercompany flows.
