TIN and VAT Number Connection

Importance of Accurate TIN Validation 

It is crucial to validate TINs to ensure: 

1. Proper Tax Reporting: An incorrect TIN can lead to tax disputes and incorrect tax filings.

For both individuals and businesses, ensuring the accuracy of the TIN is fundamental for the proper functioning of the tax system in Azerbaijan.
