Primetax Guide: What Constitues a "Qualifying Foreign Credit Institution" in Türkiye?

1. Why lender classification matters

A Turkish company borrowing from abroad may face several different taxes and compliance rules on the same financing. The status of the foreign lender can materially change the result for interest withholding tax, VAT and documentary taxes. These consequences should be analysed before the loan agreement is executed and before the first drawdown, rather than only when interest is paid.

The principal tax consequences

For interest withholding tax, Turkish domestic law currently applies a 0% rate to interest on qualifying loans from foreign states, international institutions, foreign banks and certain other foreign lending institutions. Interest on other foreign loans is generally subject to 10% withholding tax, subject to any lower rate available under an applicable double-tax treaty.

For VAT, Revenue Administration practice distinguishes between financing supplied by a foreign credit institution and financing supplied by a non-financial or non-authorised lender. Interest on a qualifying foreign-credit-institution loan is treated as falling within the banking-type exemption in Article 17/4-e of the VAT Law. Interest on financing from a lender that does not have the relevant credit-institution status is generally subject to reverse-charge VAT in Türkiye.

For stamp tax and related fees, Turkish legislation provides a specific exemption for documents relating to loans extended by banks, foreign credit institutions and international institutions. If the lender does not fall within the relevant category and no other exemption applies, the loan documentation may be subject to stamp tax if it falls within the Turkish stamp-tax nexus.

These rules are related, but they are not interchangeable. The correct analysis should therefore be performed tax by tax.

2. There is no single “QFI” test under Turkish law

The most important point for structuring is that Turkish law does not provide one master definition that automatically produces the same result across all taxes. Different provisions use different wording and, in some cases, different conditions.

Withholding tax applies a narrower test

For the 0% domestic withholding-tax rate, the relevant rule covers foreign states, international institutions and foreign banks, as well as institutions that are authorised in their country of residence to grant loans in the ordinary course and that lend not only to related parties but to real and legal persons generally. The “not only related parties” condition is therefore important where the lender is a captive finance or treasury company.

Stamp tax focuses on foreign credit-institution status

For the stamp-tax and fee exemption, the Capital Movements Circular describes a foreign credit institution as an institution authorised under the laws of its country of residence to provide financial resources and for which lending is one of its principal activities. The wording does not replicate the separate withholding-tax requirement that loans must also be made to unrelated persons.

VAT follows the nature and regulatory status of the lender

For VAT, the Revenue Administration has taken the view that a foreign loan can be treated as analogous to a banking transaction, and therefore exempt under Article 17/4-e, where the foreign lender is recognised as a credit institution under the legislation of its home jurisdiction. If it is not, the financing service is generally treated as a taxable service supplied from abroad.

Accordingly, the practical question is not “Is the lender a QFI?” in the abstract. The question is whether the lender satisfies the specific Turkish test relevant to the tax being analysed.

3. Withholding tax on interest payments

Article 30 of Corporate Tax Law No. 5520 provides the statutory framework for withholding from certain payments to non-resident corporations. The applicable rates for interest are determined by the current rate decision and distinguish qualifying institutional lenders from other creditors.

0% domestic withholding-tax rate

The 0% rate applies to interest paid on loans obtained from foreign states, international institutions and foreign banks. It also applies where the lender is an institution that is authorised in its country of residence to grant loans and, as part of its ordinary lending activity, provides credit not only to related entities but to real and legal persons generally.

This test should be evidenced, not assumed. A regulatory licence or official confirmation that permits lending is important, but for the 0% withholding-tax category the lender’s actual lending model and customer base may also be relevant. A licence that permits lending only as an incidental activity, or a treasury vehicle that lends exclusively within its group, should not automatically be treated as satisfying the 0% domestic-rate test.

Other foreign lenders: generally 10%

Where the foreign lender does not fall within the qualifying 0% category, Turkish domestic law generally subjects the interest to 10% corporate withholding tax. This is the relevant practical domestic-law comparison; the 15% rate stated in Article 30 is a statutory framework rate that has been reduced for particular categories by the applicable rate decision.

Do not apply the 0% rate merely because the lender is “financial”

Descriptions such as finance company, group finance centre, treasury company, investment vehicle, fund, payment institution or fintech do not by themselves establish the 0% rate. The legal authority to lend, the place of regulation and, where relevant, whether lending is made to unrelated customers should be established before the Turkish borrower applies the reduced rate.

Domestic interest withholding rates are principally determined under Corporate Tax Law Article 30 and Decision No. 2009/14593, as subsequently applicable.

4. VAT treatment of foreign loan interest

A loan provided to a Turkish borrower by a non-resident lender is a financing service. Where the service is taxable in Türkiye and the lender has no Turkish establishment that accounts for the tax, the Turkish borrower would normally account for VAT under the reverse-charge mechanism. The critical issue is whether the banking-type exemption applies.

Foreign bank or qualifying foreign credit institution

The Revenue Administration has consistently treated foreign-loan transactions supplied by a lender that is recognised as a credit institution under its home-country legislation as equivalent in nature to banking transactions. On that basis, the interest is treated as exempt from VAT under Article 17/4-e of the VAT Law, even though the foreign lender itself is not subject to Turkish banking and insurance transactions tax.

Non-financial or non-authorised lender

If the foreign lender is not accepted as a bank or credit institution under the relevant home-country rules, interest and similar financing charges are generally subject to Turkish VAT under the reverse-charge mechanism at the standard rate, currently 20%. This treatment commonly arises for loans from ordinary foreign parent companies and group treasury entities that are not regulated lenders.

Reverse-charge VAT should not automatically be described as a permanent financing cost. A Turkish borrower carrying on VATable activities may generally deduct the VAT subject to the ordinary deduction rules, whereas a borrower with exempt or restricted recovery may bear all or part of the amount as a cost. The cash-flow and recoverability position should therefore be modelled separately.

The VAT test is not identical to the withholding-tax test

The withholding-tax 0% category expressly looks at lending beyond related parties. VAT administrative practice focuses more directly on whether the lender is treated as a credit institution under the laws of its jurisdiction. A lender should therefore be tested separately for each tax rather than assuming that one conclusion controls the other.

5. Stamp tax and fee exemption

Turkish stamp-tax legislation contains a specific exemption for documents relating to loans granted by banks, foreign credit institutions and international institutions. The exemption is contained in Table (2) IV/23 attached to Stamp Tax Law No. 488. Related fee relief is also addressed in Article 123 of the Fees Law.

Who is a foreign credit institution for this purpose?

Article 32 of the CBRT Capital Movements Circular states that a foreign credit institution is an institution that is authorised under the laws of its country of residence to provide financial resources and for which lending is one of its principal activities. The same provision gives examples of international institutions, including the World Bank, the International Monetary Fund, the European Bank for Reconstruction and Development and the Islamic Development Bank, together with similar institutions providing development or reconstruction financing.

This formulation is important because it is not enough that the lender has spare cash, has a treasury function or is permitted under its corporate objects to advance money to group companies. The Turkish exemption is tied to the lender’s institutional status and lending activity.

Scope of the exemption

Where the lender qualifies, documents relating to the provision and repayment of the loan, together with qualifying annotations and security documents, can benefit from the statutory exemption. The exemption should nevertheless be checked document by document, particularly where the transaction includes guarantees, security packages, accession agreements, amendments or separate fee arrangements.

If the lender does not qualify

A loan agreement that does not benefit from the exemption may be subject to Turkish stamp tax at the general proportional rate of 0.948% (9.48 per thousand), subject to the annual statutory cap and the rules determining whether a document executed abroad has become taxable through its use, submission or other relevant connection with Türkiye.

Foreign governments should not automatically be grouped with foreign credit institutions for stamp-tax purposes. The wording of the stamp-tax exemption refers to banks, foreign credit institutions and international institutions, and the applicable category should be identified on the facts.

6. How foreign credit-institution status is evidenced

The status of the lender should be documented before the Turkish borrower relies on a tax exemption or a 0% withholding-tax rate. In practice, the intermediary Turkish bank may also request evidence before processing or recording the foreign loan.

CBRT evidence requirement

Under Article 23(3) of the CBRT Capital Movements Circular, where the Turkish intermediary bank is uncertain whether the foreign lender is a credit institution, the borrower may be required to demonstrate that the lender is authorised to extend credit under the laws of the relevant country. The provision contemplates an official document from the competent authority in the lender’s jurisdiction, confirmed by the Turkish diplomatic mission or economic counsellor in that country, and submitted to the intermediary bank.

Evidence should address the relevant tax test

A regulatory certificate may be sufficient to establish that lending is legally permitted, but it may not by itself prove every element of the withholding-tax test. Where the 0% interest withholding rate is being claimed for a non-bank lender, the file should also support the proposition that the institution lends in the ordinary course to persons outside its own group.

A robust file may therefore include the lender’s regulatory licence, certificate or regulator letter, relevant extracts from local financial-services legislation, constitutional documents, audited financial statements, public product information, evidence of third-party lending activity and, where appropriate, a legal opinion from counsel in the lender’s jurisdiction.

The documentation should be current when the loan is entered into and retained with the Turkish borrower’s tax file. If the lender’s licence, ownership, business model or regulatory perimeter changes, the Turkish analysis should be revisited.

7. Group treasury companies and related-party lenders

Group treasury entities require the most careful analysis because their economic function may look similar to that of a financial institution while their legal status is different. A treasury company can raise funds centrally, manage group liquidity and make multiple intercompany loans without necessarily being a regulated credit institution in its home jurisdiction.

Withholding tax

A treasury company that lends only to group companies will generally have difficulty meeting the domestic 0% withholding-tax category applicable to non-bank institutions, because that category requires lending not only to related parties but to real and legal persons generally. In that case, the domestic withholding rate on interest is generally 10%, subject to treaty relief.

VAT

If the treasury company is not recognised as a credit institution under its home-country law, interest paid by the Turkish borrower will generally be subject to reverse-charge VAT. The fact that the lender is the group’s central finance company or that it has borrowed from third-party banks does not, by itself, convert the treasury company into a qualifying foreign credit institution for Turkish VAT purposes.

Stamp tax

The same caution applies to the stamp-tax exemption. A group finance company should not rely on the exemption merely because lending appears in its corporate objects or because it is economically engaged in treasury activity. The Article 32 test - legal authorisation to provide financial resources and lending as a principal activity - should be supported by the home-country legal and regulatory framework.

The Turkish borrower should therefore avoid using a single “QFI memo” for all taxes. A short tax-by-tax status matrix is a more reliable way to document the position.

8. Double-tax treaties and beneficial ownership

Failure to qualify for the domestic 0% withholding-tax category does not necessarily mean that the Turkish borrower must ultimately bear a 10% withholding rate. Where Türkiye has a double-tax treaty with the lender’s country of residence, the treaty’s interest article may provide a lower maximum rate or, in limited cases, another form of relief.

Treaty relief is a separate analysis. The lender must generally be a resident of the treaty jurisdiction and the conditions of the relevant interest article must be met. Where the treaty requires the recipient to be the beneficial owner of the interest, an intermediary or conduit entity may not be entitled to the treaty rate simply because it is the contractual lender.

This is particularly important in back-to-back financing and group treasury arrangements. If the foreign lender is contractually obliged to pass substantially the same interest to another entity, or has limited control over the income, the beneficial-ownership and anti-abuse provisions of the applicable treaty should be reviewed before treaty relief is claimed.

The domestic 0% institutional-lender rate and treaty relief should therefore be treated as two separate routes. If the domestic 0% test is satisfied, a treaty claim may be unnecessary for the interest withholding rate. If it is not satisfied, the treaty may still reduce the domestic 10% rate where its conditions are met.

9. RUSF and other financing rules remain separate

Classification as a foreign bank or credit institution does not, by itself, resolve every Turkish financing tax. In particular, Resource Utilisation Support Fund (RUSF / KKDF) consequences depend principally on the currency, maturity, borrower and statutory exemptions applicable to the foreign loan.

For foreign-currency and gold loans obtained from abroad by Turkish residents other than banks and financing companies, the current maturity-based RUSF rates are generally 3% for an average maturity of less than one year, 1% from one year to less than two years, 0.5% from two years to less than three years and 0% for three years or more. Turkish-lira loans obtained from abroad are generally subject to 1% where the average maturity is less than one year and 0% where it is one year or more, subject in each case to specific exemptions and borrower categories.

Foreign-exchange rules under Decree No. 32 and the CBRT Capital Movements Circular also apply independently. A Turkish company may be restricted in borrowing foreign currency depending on its foreign-currency income, outstanding foreign-currency loan balance and the statutory exemptions. Foreign loans are generally required to be drawn through a Turkish bank unless a specific exception applies.

Where the foreign lender is related to the Turkish borrower, transfer pricing, thin capitalisation and the financing-expense-limitation rules should also be considered. A favourable lender classification for withholding tax, VAT or stamp tax does not disapply those corporate-income-tax rules.

10. Practical review before a Turkish borrower signs

The lender-classification analysis is most effective when completed before the loan agreement and payment mechanics are finalised. The following sequence helps prevent a financing from being documented on the assumption of a tax exemption that is not available.

Step 1 - identify the lender precisely

Confirm the contracting and funding entity, its jurisdiction, legal form, regulator and licence. Do not rely only on the group name or on the status of another entity within the lender’s group.

Step 2 - map the lender’s legal authority and actual business

Determine whether the lender is legally authorised to provide financial resources and whether lending is one of its principal activities. If the 0% domestic withholding-tax rate is intended, also confirm whether the lender extends credit to unrelated real or legal persons and retain evidence of that activity.

Step 3 - analyse each Turkish tax separately

Prepare separate conclusions for interest withholding tax, VAT and stamp tax. A positive conclusion for one tax should not be copied automatically to another. Identify any treaty rate separately from the domestic-law rate.

Step 4 - secure evidence before drawdown

Agree with the intermediary Turkish bank what documentary evidence it requires. Where there is uncertainty over foreign credit-institution status, obtain the official authorisation evidence contemplated by Article 23(3) of the CBRT Circular before the loan is funded.

Step 5 - review the remaining financing taxes and restrictions

Check RUSF, foreign-currency borrowing eligibility, transfer pricing, thin capitalisation, financing expense limitation and any security or guarantee taxes. The headline lender classification is only one part of the Turkish financing analysis.

Step 6 - revisit status when facts change

A change in the lender, licence, funding platform, customer base or treaty residence may change the Turkish treatment. Refinancings, novations and transfers of the loan should therefore trigger a fresh lender-status review.
