What is a VAT Number?

A VAT Number is a unique number that identifies a business's VAT liability. Businesses operating in Turkey are required to obtain this number, which signifies their VAT liability. According to tax regulations, businesses that exceed a certain turnover or engage in specific activities acquire VAT liability and are thus required to obtain a VAT Number.

Significance of the VAT Number:

  1. Legal Compliance: Businesses in Turkey are required to fulfill their VAT liabilities as per legal regulations. The VAT Number serves as an indicator of this legal compliance and is a document that must be presented when requested by tax authorities.

  2. Tax Refunds and Deductions: Businesses with VAT liability can record the VAT on their purchases as expenses and deduct it from their VAT base. However, the business must have a VAT Number to be eligible for these deductions.

  3. Commercial Relationships: The VAT Number is an important identifier in commercial relationships between businesses. Especially in invoice issuance processes and in the procurement of goods/services, using this number correctly is crucial for the smooth operation of tax processes.

  4. Export and Import: For businesses engaged in international trade, the VAT Number is significant in export and import processes. This number determines the tax aspect of cross-border trade.
