For international corporations procuring engineering, architectural, or technical consultancy services from Turkey, ensuring regulatory compliance is paramount. The 2026 fiscal year introduces stricter controls under Law No. 7491, specifically regarding the “Minimum Domestic Corporate Tax” and “Foreign Earnings Repatriation” rules. This guide outlines the mandatory contract and invoicing standards required to maintain a compliant commercial relationship with your Turkish partners.
The 2026 Compliance Checklist for International Buyers
Document
Critical Requirement
Why It Matters?
Contract
Define scope as “Engineering Consultancy” (not just “Testing”).
Ensures 80% Tax Deduction eligibility for the supplier.
Invoice
Must state “VAT Exempt pursuant to Art. 11/1-a”.
Legally justifies 0% VAT charges.
Payment
Must be SWIFT transfer in FX (EUR/USD).
Mandatory for tax exemption validation.
Report
Must prove the output is used/consumed abroad.
Validates “Place of Enjoyment” rules.
Invoicing Standards: Avoiding VAT Disputes
When receiving an invoice from a Turkish service provider, ensure it contains the specific VAT exemption clause: “3065 Sayılı KDVK Madde 11/1-a gereği KDV’den istisnadır”. As detailed in our Engineering Invoicing Guide, the description of services should align perfectly with the contract. Discrepancies (e.g., Invoice saying “Lab Test” vs. Contract saying “Consultancy”) can trigger tax audits and retroactive VAT liabilities.
The “Minimum Corporate Tax” Impact
New in 2026, Turkey introduced a 10% Minimum Domestic Corporate Tax on earnings, regardless of incentives. While your Turkish partner benefits from an 80% deduction, they still face a 10% tax floor. Understanding this helps in negotiating sustainable long-term contracts, as “zero-tax” pricing models are no longer legally viable for Turkish firms. See our 2026 Risk Management Guide for details.
Contract Wording: The “Benefit” Principle
Turkish Tax Authority (GIB) strictly monitors the “Place of Enjoyment.” If your contract implies that the service improves a product for the Turkish manufacturer, VAT exemption may be denied. The contract must explicitly state that the technical report is for the exclusive use and risk management of the foreign headquarters (e.g., in Germany or USA).
Frequently Asked Questions
Can we pay our Turkish service provider via PayPal or Wise?
Direct bank transfers (SWIFT) are preferred to generate the mandatory “Foreign Exchange Purchase Certificate” (DAB/IBKB) required for tax exemptions.
What happens if the invoice lacks the VAT exemption code?
The Turkish supplier may be forced to charge 20% VAT retroactively, increasing your procurement costs.
Does the 2026 Minimum Tax affect our pricing?
Indirectly, yes. Turkish firms must account for a minimum 10% tax load, preventing predatory underpricing based on full tax evasion.
