Belarus Tax Filing Guide 2026

Overview — Tax Filing in Belarus

The Ministry of Taxes and Levies (Министерство по налогам и сборам — МНС) operates an integrated online tax administration system (Личный кабинет плательщика — taxpayer personal account) for all tax filings, payments, and compliance management. Taxpayers register on the MNS portal, obtain a UNP (учетный номер плательщика), and file all returns electronically. The system covers IIT, CIT, VAT, property tax, and other taxes. The MNS has invested significantly in digitalisation, and most tax processes are fully electronic. Taxpayers can view their tax history, submit returns, make payments, and communicate with tax inspectors through the portal.

Taxpayer Identification Number (UNP)

A UNP is mandatory for all taxpayers in Belarus — individuals, companies, and other entities. The UNP is a unique 9-digit identifier (e.g., 123456789). To obtain a UNP, register at the local tax inspectorate with a valid passport or identification document. The UNP is required for many transactions including opening a bank account, entering into employment contracts, registering property, importing/exporting goods, and obtaining business permits. Companies receive their UNP upon incorporation. Individuals can obtain a UNP online through the MNS portal. The UNP remains with the taxpayer for life and is used for all tax interactions.

Filing Deadlines — 1 April

The annual tax return deadline in Belarus is 1 April of the year following the tax year. Different taxpayers have specific obligations:

• Individuals (IIT) — annual return due by 1 April if the individual has income not taxed at source (rental, foreign income, business income, capital gains) or wishes to claim deductions
• Self-employed individuals — annual return due by 1 April, with quarterly estimated payments due on the 22nd of the month following each quarter
• Companies (CIT) — annual return due by 1 April, with quarterly estimated payments
• VAT — monthly or quarterly return by the 20th of the following month
• Property tax (companies) — quarterly return by the 22nd of the month following the quarter
• Social contributions — monthly return by the 15th of the following month

Late filing attracts a penalty of up to 40% of the assessed tax plus interest at the National Bank refinancing rate on unpaid amounts.

Self-Assessment & Quarterly Instalments

Self-employed individuals and companies must estimate their annual tax liability and pay in quarterly instalments:

• First instalment — due 22 March (25% of estimated tax)
• Second instalment — due 22 June (25% of estimated tax)
• Third instalment — due 22 September (25% of estimated tax)
• Fourth instalment — due 22 December (25% of estimated tax)

If the actual tax computed in the annual return exceeds the total instalments paid, the balance is due by 1 April. If instalments exceed the actual tax, a refund may be claimed within 5 years. Underpayment of instalments attracts interest at the refinancing rate.

MNS Online Portal (Личный кабинет)

The MNS taxpayer personal account allows taxpayers to:

• Register for UNP and tax types
• File annual and periodic returns
• Make tax payments (via bank transfer, ERIP, or card)
• View tax history, assessments, and compliance status
• Request tax clearance certificates
• Submit applications for treaty relief and tax refunds
• Communicate with tax inspectors
• Access tax legislation and guidance

Taxpayers can access the portal through the MNS website (www.nalog.gov.by) using a password or electronic digital signature. All records are stored digitally, and taxpayers can download their tax certificates and returns at any time.

Penalties & Enforcement

The MNS has broad enforcement powers under the Tax Code. Key penalties include:

• Late filing — up to 40% of the assessed tax
• Late payment — interest at the National Bank refinancing rate on unpaid amounts
• Failure to maintain records — up to BYN 5,000
• Tax evasion — 100% penalty on the evaded tax plus possible criminal prosecution
• Failure to register for tax — up to BYN 10,000 plus back taxes

The MNS may issue collection orders to banks, seize assets, or initiate legal proceedings to recover unpaid taxes. Tax clearance certificates are required for certain transactions (property sales, business transfers) and may be denied to non-compliant taxpayers.

FAQs

Can I file my tax return manually?

While the MNS encourages electronic filing, paper filing is still accepted at local tax inspectorates. However, most taxpayers and all businesses are expected to file electronically through the MNS portal.

What records do I need to keep?

Taxpayers must keep records for at least 5 years from the end of the tax year. Records include income statements, receipts, invoices, bank statements, contracts, and asset registers. The MNS may audit taxpayers and request documents at any time.

How long does it take to get a tax clearance certificate?

If all returns are filed and taxes paid, a tax clearance certificate can be obtained online through the MNS portal within 1–3 business days.
