A Tax ID number is helpful for those international KU members in completing several procedures upon their arrival, before receiving their residence permits. It will allow you to purchase health insurance, pay the residence permit card fee, open a bank account at certain banks, and perform various formalities in Türkiye. 

Obtaining a tax ID is free of charge. 

Once you have a residence permit, there will be no need to use a tax ID number. You will have your foreign ID number written on your permit card and can provide it at any official transaction.

A Tax ID application can only be made with your valid passport.

Here are the two ways you may obtain a tax ID number:



What do you need?

  1. A Turkish phone number 
  2. Your passport

How to proceed?

  1. Visit the official website of the Digital Tax Office.
  2. Fill the application page by minding the following notes:
    • If you do not have a Turkish residence permit, leave the “Identity Number” field empty.
    • Make sure to enable cookies and pop-ups on your browser since your tax ID number will be given to you as an official letter in a PDF. If you do not enable them, you cannot receive the document.
    • You should use the exact same info as written on the passport. Do not use Turkish characters, i.e. “İ.”
    • The date format is DD/MM/YYYY. If you are not sure, please indicate the dates through the calendar icons.
  3. Once you submit the form, the system will assign a tax ID number to you. 
    • The T.C./Vergi Kimlik Numarası or the Potansiyel Vergi Kimlik Numarası on the document is your Tax ID number.
