Belarus UNP Tax Identification Number Guide

Registration number (UNP) — Учётный номер плательщика​

The Unified Number of Payer (UNP — учётный номер плательщика) is Belarus's primary tax identification number, assigned by the Ministry of Taxes and Duties (MNS) to every registered taxpayer: legal entities, individual entrepreneurs, and individuals. It serves as the single identifier across tax filings, electronic VAT invoices, the Unified State Register (EGR), and cross-border withholding tax documentation.

UNP Format​

The UNP is always 9 characters long. The format differs between organisations and individuals:

Taxpayer typeFormatExample
Legal entity / Organisation9 digits (NNNNNNNNN)200988541
Individual / Sole trader2 letters + 7 digits (LLNNNNNNN)MA1953684

The first character (digit or letter pair) encodes the Belarusian region where the entity registered. The last character is a check digit calculated using a weighted modulo algorithm; any UNP failing this check is invalid. Positions 2–8 (or positions 3–8 for alphanumeric codes) form the payer's serial number within that region.

Regional prefix codes for organisations include 1 (Brest), 2 (Vitebsk), 3 (Gomel), 4 (Grodno), 5 (Minsk City), 6 (Minsk Region), 7 (Mogilev). Alphanumeric prefixes for individuals follow a similar regional pattern (MA = Mogilev, etc.).

Official Verification​

Active UNPs can be looked up in the Unified State Register (EGR) maintained by the Ministry of Justice:

Official Database — egr.gov.by

The EGR returns the entity's full legal name, registration date, registered address, and current status (active, in liquidation, or dissolved). For tax-specific status — including whether a UNP is enrolled in the ESCHF e-invoicing portal — use the MNS taxpayer portal at nalog.gov.by.

ESCHF — Electronic VAT Invoicing​

Belarus operates one of the most digitalised VAT enforcement systems in Eastern Europe. All VAT-registered entities must issue and receive electronic invoices (ESCHF — электронный счёт-фактура по НДС) through the MNS portal. The portal validates each counterparty's UNP in real time before accepting an invoice. An invalid or inactive UNP causes outright rejection — no paper workaround exists for VAT-registered transactions. The standard VAT rate is 20%.

EAEU Membership​

Belarus is a founding member of the Eurasian Economic Union (EAEU) alongside Russia, Kazakhstan, Kyrgyzstan, and Armenia. This membership shapes VAT rules for cross-border digital services and goods — in particular, the place-of-supply rules that determine when a foreign digital provider must register. Belarus is not an EU member state, so Belarusian UNPs are not verifiable through the EU VIES database.

For comparison with neighbouring EAEU tax identification systems, see the Russia TIN guide and the Kazakhstan TIN guide.

UNP for Individual Entrepreneurs — 2024 Reform​

From 1 October 2024, Belarus closed new individual entrepreneur (IE) registrations and sharply curtailed the list of activities IEs may conduct. Existing IEs whose business falls outside the now-restricted list must reorganise into a limited-liability company (OOO) by 31 December 2025. A "seamless transition" procedure preserves the IE's existing UNP, contractual relationships, and tax history in the successor OOO, avoiding a full liquidation-and-reregistration cycle.

HTP — Hi-Tech Park Special Regime​

Belarus's Hi-Tech Park (HTP) offers a preferential tax regime for qualifying IT companies under Presidential Decree No. 8. HTP residents retain their standard UNP; the regime modifies tax treatment, not the identification number. Key HTP benefits include 0% corporate income tax until 1 January 2049, VAT exemption on qualifying software and IT-service sales, and a reduced 9% personal income tax rate for employees. HTP residents that pay dividends to foreign founders must still withhold and remit income tax under their UNP.

Frequently Asked Questions​

If a Belarusian supplier's UNP is inactive in the EGR, can I still deduct input VAT on their ESCHF invoice?​

No. The ESCHF portal run by the Ministry of Taxes and Duties performs real-time counterparty validation before accepting any electronic invoice. If your supplier's UNP belongs to a liquidated, suspended, or otherwise inactive entity, the ESCHF portal rejects the invoice outright — there is no manual override. Input VAT (20%) claimed against a rejected or unverified ESCHF is treated as non-deductible, exposing the buyer to back-assessments and penalties. Always verify a supplier's UNP status in the EGR before processing payment. [1] [2]

Do foreign SaaS and digital-service companies need a Belarusian UNP, and is there a revenue threshold?​

It depends on what you sell. For digital services (streaming, SaaS, app downloads, online advertising) supplied to Belarusian B2C customers, there is no revenue threshold — registration with the MNS is mandatory from the first sale. For e-commerce goods, the threshold is EUR 10,000 in annual sales to Belarusian customers before mandatory VAT registration applies. Upon registration the MNS assigns a UNP, which becomes the login credential for the taxpayer's personal cabinet. VAT at 20% is filed and paid quarterly, due by the 20th of the month following each reporting quarter. The registration form is electronic and free of charge. [1] [2]

What withholding tax applies to dividends and royalties paid to a foreign counterparty, and what happened to treaty rates in 2024?​

Belarus suspended relevant provisions of double-taxation agreements with 27 states — all EU member states, the USA, the UK, Canada, Norway, Switzerland, and others — effective 1 June 2024 through 31 December 2026. During this suspension, domestic rates replace treaty-reduced rates: 25% on dividends paid to residents of those "unfriendly" states (up from the typical treaty rate of 5–15%), and 25% on interest payments. Royalties and management fees paid to non-residents without a local permanent establishment are subject to 15% withholding at the domestic rate. The Belarusian payer's UNP must appear on any withholding remittance documentation filed with the MNS. Always confirm whether your country's treaty is among those suspended before quoting net rates. [1] [2]

Does an HTP resident company still need a UNP, and which taxes does the HTP regime actually waive?​

Yes — every HTP resident receives and retains its UNP; the special regime changes tax treatment, not the identification number. Under Presidential Decree No. 8, HTP residents are exempt from corporate income tax (0% CIT until 1 January 2049) and from VAT on qualifying software, IT-service, and property-right sales. Employees benefit from a reduced 9% personal income tax rate. However, HTP residents that act as tax agents — for example, paying dividends to foreign founders — must still withhold and remit income tax at the applicable non-resident rate using their UNP. Activities outside the approved HTP list remain fully taxable under standard rules. [1] [2]

Individual entrepreneurs registered in Belarus before October 2024 have been told to convert to an LLC — does their UNP survive the transition?​

Yes. Belarus introduced a "seamless transition" procedure allowing existing individual entrepreneurs — whose new registrations were closed on 1 October 2024 and whose permitted activity list was sharply curtailed — to reorganise into a limited-liability company (OOO) without liquidating first. Under this procedure the newly created OOO inherits the IE's UNP, tax history, and existing contracts, minimising re-registration friction. IEs operating in activities now outside the permitted list must complete the transition by 31 December 2025, after which they may no longer operate as IEs. An error in the application or a missing certificate can cause registration refusal, so assembling a complete document set before filing is critical. [1] [2]

Why does my validation software reject a UNP that the EGR shows as active?​

UNPs for individuals use an alphanumeric format (two-letter regional prefix + 7 digits), not the all-numeric format used for organisations. Validation libraries that only implement the all-digit checksum will reject any individual UNP containing letters. Additionally, the check-digit algorithm for Belarusian UNPs uses a proprietary weighted modulo calculation — not the standard Luhn algorithm used for credit cards. If your integration uses a generic Luhn check or only handles 9-digit strings, it will produce false negatives for individual UNPs. The reference implementation is publicly documented and should handle both format variants before applying the check-digit test. Verify format compatibility in your library before production deployment. [1] [2]
