Russian employers, many banks, and a long list of contracts ask for an INN (ИНН) before they will finish onboarding. The number is a tax identifier from the FNS (Federal Tax Service). It does not by itself prove tax residence or replace a visa, RVP, or VNZh.
How do you apply in practice?
Bring a passport (with a notarised Russian translation when the office requires one), evidence of lawful stay or residence, and your migration registration or residence address details. The classic paper route uses application form 2-2-Uchet at a territorial tax inspectorate. Many newcomers use an MFC (многофункциональный центр) instead when the local "My Documents" centre accepts foreigner tax registration.
If you already have a working personal account on nalog.gov.ru or a verified Gosuslugi login, you can often request an electronic extract or file without standing in a Moscow queue. A verified portal account is the hard part for new arrivals; see set-up-gosuslugi-russia. Some people discover an INN already exists because an employer reported income and the FNS assigned the number without a separate visit. Check the FNS "find my INN" service before you open a second file.
Keep the spelling of your name identical across passport, registration slip, and tax forms. Cyrillic transliteration mismatches are a common reason banks reject payroll setup later.
What do you use the INN for after it arrives?
Payroll registration almost always needs the number. Bank compliance teams in Sber, T-Bank, VTB, and similar retail banks frequently ask for it during AML (anti-money-laundering) checks when you open or upgrade an account; pair this with open-bank-account-russia. Lease paperwork, freelance contracts, and some utility or paid-service setups can also request it once you settle in monthly-budget-russia territory.
OMS (compulsory medical insurance) enrolment for eligible residents is a separate process and may ask for SNILS and status documents more than the INN, but having a clean tax record still reduces friction; see enrol-oms-russia. Residence permits themselves are decided by the MVD, not the FNS: apply-residence-permit-russia.
Do not treat the INN as proof that you owe Russian tax on worldwide income. Tax residence and filing duties depend on presence, income source, and treaty rules. Get qualified advice if you keep foreign remote pay while living in Russia.
Common misconceptions
The INN is not a residence permit and cannot fix an expired visa or missing address registration.
Ordering a "fast INN" from a random Telegram agent does not beat the free FNS or MFC route. A duplicate or mistyped record is worse than waiting a few working days for the official extract.
Summary
Apply once through the FNS, an MFC, or a verified online account, then reuse the same INN everywhere. Match passport spelling carefully and check whether an employer already triggered an automatic assignment.
Confirm current document lists on nalog.gov.ru or Gosuslugi before you travel to a busy inspectorate, and keep one clean record rather than filing twice when a bank search fails.
