How do you get a Turkish tax number in 2026?

Open Dijital Vergi Dairesi (the Digital Tax Office) and use “Potential Tax Number Application for Foreigners.” Do not rely on old instructions that send you only to the retired Interactive Tax Office wording or to a paid agent's form.

Enter your name, surname, sex, birthplace, parents' names, country, passport number, mobile number and Turkish address as the current form requests. If the portal requests a passport image or another upload during your session, use a clear image of the identity page and follow its current size and format rules. Match transliteration, spacing and passport number exactly; a small difference can create trouble when a bank or land registry searches the record.

Download or print the result and store its verification details. The Revenue Administration is Gelir İdaresi Başkanlığı, or GİB (the national tax authority), so check that the website is on gib.gov.tr before entering passport data.

Take the original passport and a copy to a vergi dairesi (tax office). Bring the Turkish address and contact details used in your other records, plus the failed application reference or old tax document if one exists. Ask the office to search by passport and identity details before creating anything new.

Once Türkiye assigns a foreigner identity number through the residence system, public and private services may use that number in place of the earlier tax identifier. Do not assume both records merged correctly. If a bank, utility company or title office sees different names or two tax records, ask GİB to correct or link the official record; never solve it by submitting a third application.

A bank may request it during customer checks. The land registry uses tax identification in property work, and utilities or official fee payments can also require it. Each transaction has its own documents: the number does not replace a passport, lawful entry evidence, address proof, bank source-of-funds review or residence permit.

Payroll registration and opening a business are separate tax processes. An employer may need to register employment and withholding records. A sole trader or company needs the correct taxpayer registration, activity and filing setup rather than only a potential number.

Likewise, obtaining the number does not by itself make you tax resident in Türkiye. Tax residence and liability depend on the tax rules, time and home facts, income source, applicable treaty and the tax period. Get qualified advice if you work across borders, rent property or run a business.
