The euro and your Bulgarian company: what must be done by 31 December 2026
The euro has been Bulgaria's official currency since 1 January 2026, but the changeover for companies isn't finished. One important deadline remains — 31 December 2026 — plus the first year-end close fully in euro. Here's what to check.
- OOD and EOOD share capital must be converted in the Commercial Register by 31 December 2026 at the latest, with no state fee.
- 2025 accounts are in leva; 2026 accounts are fully in euro.
- Contracts remain valid — amounts are converted at 1.95583 and rounded to the cent.
- Mandatory dual pricing ended on 8 August 2026, but price monitoring continues.
The key dates
| Date | What |
|---|---|
| 8 August 2025 | Dual pricing in leva and euro begins. |
| 1 January 2026 | The euro becomes the official currency. Books, invoices and returns move to euro. |
| 31 January 2026 | End of dual circulation of leva and euro cash. |
| 8 August 2026 | End of mandatory dual pricing. |
| 30 September 2026 | Deadline for publishing 2025 accounts — a convenient moment to file the converted articles too. |
| 31 December 2026 | Final deadline for converting share capital in the Commercial Register. |
1. Share capital
On 1 January 2026 the Registry Agency automatically converted companies' capital to euro. That isn't the end of it. Companies must themselves amend their articles of association and file them with the Commercial Register.
- Deadline: together with the first application to the register after the euro was introduced, and no later than 31 December 2026.
- Fee: no state fee is charged for the conversion.
- How: the number of shares doesn't change — their nominal value is recalculated and rounded to the cent. The rounding difference goes to reserves, not to profit.
- Resolution: a decision of the sole owner or of the partners' general meeting is required.
If you filed your 2025 accounts without the converted articles, don't put it off — only a few months remain before the final deadline.
2. Accounting
- The 2025 annual financial statements were prepared in leva.
- Balances at 1 January 2026 were converted to euro at 1.95583 and rounded to the cent.
- In the 2026 accounts, the 2025 comparatives are presented in euro.
- Check that rounding differences were booked correctly and that all accounts were closed properly at the changeover.
3. Contracts
All contracts remain valid. Amounts in leva are read as euro at the fixed rate. Still, review:
- long-term contracts — rent, leasing, subscriptions, framework agreements with prices;
- contracts with a threshold or limit in leva (for example "up to BGN 10,000");
- employment contracts — salaries are now paid in euro.
An amendment isn't mandatory, but for important contracts it adds clarity and prevents disputes over rounding.
4. Invoices, software and tills
- Invoices are issued in euro and numbering continues without a break.
- Fiscal devices and sales software (SUPTO) must work in euro.
- Clean old leva references out of your templates if they are no longer needed.
5. Prices
Mandatory dual pricing ended on 8 August 2026. Monitoring of unjustified price increases linked to the euro continues, however, and the penalties are serious. Document the reasons for any price change — higher supply, labour or energy costs.
6. The first year-end in euro
The 2026 year-end close is the first fully in euro. Start preparing in November — see the detailed year-end checklist.

Frequently asked questions
What happens if I don't convert the share capital by year end?
You breach a legal obligation and risk sanctions. In practice future changes also become harder — transferring shares, changing the manager, bank loans and public procurement.
Do I have to sign amendments to every contract?
No — contracts remain valid and amounts are converted at the fixed rate. An amendment is advisable for long-term contracts with many amounts or unclear wording.
How is rounding done?
The amount in leva is divided by 1.95583 and the result rounded to two decimal places: if the third decimal is 5 or more, the second is rounded up.
Has the minimum capital for an EOOD changed?
Yes — the minimum capital for an OOD or EOOD is now €1, and for a joint-stock company (AD) €25,000. The minimum nominal value of a share is one euro cent.
