Taxation & tax disputes in Türkiye

Tax disputes, transaction tax issues and cross-border tax coordination.

Turkish tax planning must distinguish corporate taxation under Law No. 5520 from personal income, VAT, withholding and procedural requirements. Residence, source and the transaction’s substance determine the analysis. Current minimum-tax, exemption and reporting provisions require specific review; an investment incentive or treaty position should not be treated as eliminating all domestic tax obligations.

Identify the tax, relevant period, taxpayer and decision before calculating exposure or challenging an assessment. Reconcile returns with contracts, accounts and payment evidence, including any cross-border position. Relief, incentives and treaty treatment require their own eligibility review. Preserve the assessment and service record, then compare the available objection and court routes without assuming that an objection suspends collection.

Questions about your matter

How do I start a taxation & tax disputes enquiry in Türkiye?

Identify the jurisdiction, the people involved, any existing proceeding or deadline, and the result you need. A short chronology and the key documents help define the proposed engagement before local professional arrangements are confirmed.

Can a cross-border matter involve more than one legal system?

Yes. Türkiye may be one part of a wider matter involving another place of residence, contracting party, asset or forum. Applicable law, jurisdiction and enforcement should be assessed separately, using the relevant national and international rules.

Does this guide establish a lawyer-client relationship?

No. An enquiry or use of this guide does not establish an engagement. Conflicts, professional authority, scope, responsibilities and fees must be confirmed before work is undertaken.
