3-NDFL tax return in Russia for foreign individuals: who must file, income types, deadlines, deductions and how to submit to FTS.
Most foreign nationals working for a Russian employer never file a personal tax return — their employer withholds NDFL from salary and handles everything. But once a foreign individual has any income outside that employer relationship — selling property, receiving dividends, earning abroad, making a crypto gain, or simply wanting to claim a deduction they're entitled to — the 3-NDFL declaration becomes necessary. This guide explains who must file, what to declare, which deductions are available (and to whom), and how the process works in practice.
Filing is mandatory when a Russian tax resident or non-resident has income on which NDFL was not withheld by a tax agent. The most common situations for foreign individuals:
Sale of property (apartment, car, land) before the minimum ownership period expires — 3 years for inherited/gifted property, 5 years for purchased property generally;
Foreign-source income received by a Russian tax resident — salary from a foreign employer, rental income from overseas property, foreign dividends, foreign interest;
Cryptocurrency gains — disposals via foreign exchanges where no Russian tax agent is involved (see our guide to crypto taxation);
Gifts of cash or property from non-relatives (gifts between close relatives are tax-free);
Lottery and prize income above RUB 4,000;
IP on the general regime (ОСН) — sole traders on ОСН must file even with zero income;
Any income where the payer did not withhold tax — for example, rental income from a private individual tenant paying in cash.
Filing is voluntary (but often worthwhile) when a resident wants to claim deductions not applied by their employer — such as the property purchase deduction on a Russian apartment, education or medical treatment deductions, or a foreign tax credit.
Tax residency — determined by the 183-day rule — governs what income must be declared and what deductions can be claimed. The difference is significant:
A foreign individual who bought an apartment in Russia but is a tax non-resident cannot claim the property purchase deduction — it requires resident status. The deduction becomes available once they have been resident for a full calendar year, and can then be applied retroactively to NDFL paid in that year. The deduction cannot be applied to years when the individual was a non-resident.
The most valuable deduction for many foreign individuals. A resident who buys residential property in Russia may deduct up to RUB 2,000,000 of the purchase price from taxable income (saving up to RUB 260,000 in NDFL), plus up to RUB 3,000,000 of mortgage interest paid. The deduction is applied against NDFL from employment or other income declared in the return, and any unused portion carries forward to future years until exhausted.
Residents may deduct expenses on education (their own, or children's up to age 24), medical treatment (for themselves, spouse, parents, children), life insurance premiums and voluntary pension contributions — each category with its own annual ceiling. These deductions are applied in the year the expense was paid and do not carry forward.
A resident who paid tax abroad on income that is also taxable in Russia may claim a credit against Russian NDFL — reducing double taxation. The credit is capped at the Russian tax amount on that income and requires documentation of the foreign tax paid (a tax certificate from the foreign authority or bank statement showing withholding). With many bilateral tax treaties suspended or modified, this credit has become the primary mechanism for avoiding double taxation on foreign income for individuals.
30 April: deadline for mandatory declarations (income that must be reported);
15 July: deadline for payment of any NDFL due under the return;
No deadline for purely voluntary returns (claiming deductions only, with no unreported income) — these can be filed at any time within 3 years of the tax year in question;
Late filing penalty: 5% of the unpaid tax per month of delay, minimum RUB 1,000, maximum 30% of the unpaid amount;
Late payment interest: 1/300 of the CBR key rate per day on the unpaid balance.
Check whether your income situation triggers a mandatory filing obligation — if in doubt, assume yes
Confirm your tax residency status for the relevant year before completing the return — it determines both what you declare and what rates apply
Obtain an INN if you don't already have one — you need it before you can file
