Rules: Conversion of shares, stakes, capital

After 01.01.2026, the capital declared in the Commercial Register will be converted and updated automatically

Commercial companies will have the obligation to update their articles of association/ statutes by converting the capital into euros and then declaring the updated document in the Commercial Register.

There are three possible scenarios:

  • Contract concluded and effective before 01.01.2026 – amounts are agreed in BGN.
  • Contract concluded and effective after 01.01.2026 – amounts are agreed in EUR.
  • Contract concluded before 01.01.2026 but effective after that date – amounts are agreed in BGN, since the decisive factor is the date of conclusion of the contract.

There is no legal obligation for employers to issue payslips in both currencies, as dual display applies only to consumer relations. However, employers may choose to do so at their discretion.

According to official information from the Bulgarian National Bank, IBANs will remain unchanged. Only the balances of BGN accounts will be converted into EUR as of 01.01.2026.

Even after the BGN is phased out, companies are still required to maintain a bank account in a Bulgarian bank in order to make payments to institutions.

The relevant factor is the tax period for which the declaration is submitted, not the accounting date. Amounts must be stated in the official currency valid at the end of that tax period.

Example: An invoice with a tax point in October 2025, issued in BGN but recorded in January 2026, must be declared in BGN, since the official currency for October 2025 was BGN.

The special rounding rule applies to each component of remuneration that forms part of the total “amount payable,” including derivatives of other accruals.

Additional clarifications:

  1. Sick leave compensations should also be rounded under the special rule.

Deductions, however, follow the general rounding rules, as applying the special rule would put the individual in a less favorable position.

 

No. All payments made before that date must be in the official currency valid at the time of payment – the Bulgarian lev.

If the question refers to payroll software (e.g., STIL), this depends on the service provider. It is expected that functionality will be developed to generate reports in the official currency valid for the respective period.

No amendments to existing contracts are required. Payments must be made in the official currency valid at the time of payment. For rounding, the general rules under Articles 12 and 13 of the Euro Introduction Act apply.

The law does not provide for special rules, but it specifies that all unpaid public liabilities and amounts unduly paid or collected before the euro adoption will be converted into EUR as of 01.01.2026, according to the general rules on conversion and rounding. After that date, all public receivables are to be paid in EUR.

Submission of Payroll Data

All December 2025 salaries must be reported in BGN, even if entered in January.

All January 2026 salaries and onward must be reported in EUR. This also applies to adjustments for closed periods.

Sb will send updated forms in November 2025.

Sb recommendation: Switch to DataHub – an automated platform for submitting payroll information.

Payslips for December 2025 → in BGN (unless explicitly agreed for dual issuance).

From January 2026 → all payslips and reports (accounting, statistics, provisions, output files) will be generated only in EUR

Payments

File structure does not change – only the currency.

Bank files generated before 01.01.2026 → in BGN; after 01.01.2026 → in EUR.

Sb recommendations:

  • temporarily freeze payments at the end of December, or
  • plan dates in advance to avoid delays.

Penny tests are not needed.

System Integrations (HR/ERP/Payroll)

  • As of 01.01.2026, all integrated data must be submitted in EUR
  • For information concerning December 2025, amounts must still be submitted in BGN

Employment Documentation

Contracts prepared in December 2025 must be in BGN.

Contracts prepared from January 2026 → in EUR.

Sb recommendation: avoid new hires in the last 2 weeks of 2025 to ensure a smooth transition.

If an employee starts work in January but the contract is signed in December → include them in the December cycle, so it remains in BGN.
