10 Essential Questions About TIN in Uzbekistan
Common Questions
1. What is a TIN in Uzbekistan?
In Uzbekistan, the Tax Identification Number is commonly known as the INN.
The INN is the primary identifier for all tax-related activities. However, a major shift occurred in 2021: while legal entities continue to use the 9-digit INN, individuals (including foreign directors and sole proprietors) now use the 14-digit PINFL as their universal tax identifier. Without these numbers, a business cannot issue electronic tax invoices (E-faktura), clear customs, or open a local corporate bank account.
