Turkish VAT returns

Once registered for value added tax (VAT) in Turkey, businesses must report all taxable transactions and remit VAT due to the Revenue Administration (Gelir İdaresi Başkanlığı – GİB), Turkey’s federal tax authority.

VAT returns in Turkey are generally filed monthly.

• Monthly filing is mandatory for both resident and nonresident VAT-registered businesses.
• There are no standard quarterly or annual return options under Turkish VAT law. 
• Businesses must submit returns for every month in which taxable transactions occur.

VAT filing obligations are established as part of the taxpayer’s VAT registration profile with the GİB.

VAT returns must typically be submitted by the 26th day of the month following the end of the reporting period. VAT payments are due by the same date.

For example, VAT for January must be filed and paid by 26 February.

If the deadline falls on a weekend or public holiday, it may be extended to the next working day according to GİB rules.

All VAT-registered businesses in Turkey must maintain detailed financial and tax records, including:

• Electronic invoices (e-Fatura/e-Arşiv) issued and received
• Sales and purchase books supporting VAT calculations
• Import and export documentation
• Accounting ledgers maintained in accordance with Turkish bookkeeping standards
• Electronic records submitted via the GİB’s digital platforms

Records must be retained for at least five years and must be made available to the tax authority upon request.

VAT payments are due on the same day as the return filing deadline (generally the 26th of the following month). Late payments may lead to:

• Interest charges on overdue amounts
• Administrative fines
• Suspension of digital invoicing capabilities

Input VAT may be offset against output VAT if the expenses are related to taxable business operations, such as:

• Inventory or goods for resale
• Machinery, equipment, or capital goods
• Utilities, rent, and professional services
• VAT on imports tied to taxable activities

To be deductible, input VAT must:

• Be supported by a valid, compliant invoice (typically an e-Fatura)
• Be properly recorded in the accounting system
• Relate to taxable or zero-rated supplies

Input VAT cannot be deducted for exempt supplies or personal expenses.

VAT returns must be filed electronically through the GİB Interactive Tax Office using the taxpayer’s digital certificate.

VAT payments can be made via:

• Online banking linked to GİB
• Designated government payment portals

Noncompliance with Turkish VAT obligations may result in:

• Fines for late or non-filed returns
• Interest on overdue VAT
• Penalties for incorrect, misleading, or incomplete filings
• Suspension of invoicing rights through the e-Fatura system

Penalties are outlined in Turkish tax legislation and may vary based on the severity and frequency of noncompliance.

If input VAT exceeds output VAT in a reporting period, the excess may be:

• Carried forward to offset future VAT liabilities, or
• Refunded, subject to approval by the GİB

Refunds are subject to document verification and may involve additional audit procedures. Processing timelines may vary depending on the taxpayer’s compliance history and the complexity of the claim.
