NRA with important clarifications on the declaration and payment of liabilities from January 1, 202

In connection with the introduction of the euro as an official currency in the Republic of Bulgaria from 01.01.2026, the National Revenue Agency makes the following clarifications:

Regarding payments to the National Revenue Agency (NRA):All public receivables established or collected by the NRA are paid only in euros. This is also valid in the period of double circulation of euro and BGN until 31.01.2026, given the fact that all payments to the NRA are made cashless, and the period of double circulation provided for in the Law on the Introduction of the Euro in Bulgaria (ZVERB) applies only to cash payments. During the period of double circulation, if desired, customers can pay their obligations in BGN only through banks or other payment service providers (PSPs), which provide the opportunity to order a non-cash payment by depositing the amount for the transfer at a cash desk at an office of the bank or PSP. In these cases, the PSP orders the currency conversion amount into euro to the respective account of the NRA.

The converted amounts are entered as of 01.01.2026 as liabilities/amounts paid in EUR.

Regarding the documents issued by the NRA:In the acts and documents issued under the Tax and Social Security Procedure Code, after 01.01.2026 and referring to periods before this date, the monetary values are indicated in BGN. For periods after 01.01.2026, monetary values are indicated in euro. This applies both to supporting documents issued by the NRA, such as. a certificate for declared data, etc., as well as for audit acts issued by revenue authorities and acts for establishing obligations.

Regarding the provision of information on liabilities in the electronic services of the National Revenue Agency:The National Revenue Agency converts and rounds according to the rules of Art. 12 and 13 of the ZBRB all outstanding liabilities and overpaid or unduly paid amounts available in the DOS of the persons as of 31.12.2025. In this regard, in the electronic service "Statement of liabilities with the possibility of payment", the individual liabilities are displayed in euros. In compliance with the requirements of the BEAST in the period 01.01.2026 – 31.01.2026, the total amount of each of the types of liabilities is shown in the report, both in EUR and converted into BGN. In the period 01.10.2025 – 31.12.2025, the "Statement of liabilities with the possibility of payment" showed the specific amount of each liabilities in BGN, the total amount of liabilities of a certain type in BGN and information only on the total amount of liabilities in EUR. In this regard, it is possible that for the same specific liabilities of the person that have not been repaid before 31.12.2025, their total amount in euro, which was indicated as of 31.12.2025, does not fully coincide with the total amount of the same liabilities indicated in the reports as of 01.01.2026, but that there is a difference of several euro cents. The difference is a consequence of the different way of currency conversion of the amounts, namely: in the period until 31.12.2025. – the total sum of all liabilities in BGN is converted from BGN to EUR; in the period after 01.01.2026 – the total sum of all liabilities converted into euro is converted from euro to BGN.

The amount of the interest rate from 01.01.2026, through which the interest due will be calculated, according to Decree of the Council of Ministers No. 347 of 29 December 2025, is determined as 8 percent is added to the interest rate on the main refinancing operations of the European Central Bank (ECB), which is in force on 1 January and July 1, respectively, of the current year. According to the rules described above, the interest rate for statutory interest in the period from 01.01.2026 to 30.06.2026 is 2.15+8=10.15%.
