EOOD/OOD euro capital conversion — 2026 guide

What was done automatically

On 01.01.2026 the registered capital was replaced with euro at the official rate 1 EUR = 1.95583 BGN (fixed under Art. 5 of the Euro Introduction Act in conjunction with Council Regulation (EC) No. 2866/98, as amended by Council Regulation (EU) 2025/1409; conversion and rounding — arts. 12–13 and 33 of the Act).

Automatic conversion does not create a new founding document. You still need to update your corporate documents.

What you must do

1. Adopt a sole-owner decision (EOOD) or general meeting protocol (OOD).
2. Update the founding act / partnership agreement with capital and shares in euro.
3. File with the Commercial Register using G1 (announcement only) or A4 (if rounding requires an adjustment of up to ±5% under ZVERB Art. 32(5)).

Deadline: 31.12.2028 (36 months from euro introduction; the copy is presented where required by law).

Where to get the data

You need amounts in leva before the euro, not the euro amounts already shown in the register after 01.01.2026.

1. Founding act / partnership agreement — best source; for OOD it lists partner shares.
2. Current-status extract from the Commercial Register portal.
3. Documents from your accountant or lawyer.

In Firmify you can upload a PDF/DOCX/photo — we try to extract capital and shares; you review and correct before generation.

How conversion is calculated

amount_EUR = amount_BGN ÷ 1.95583

Rounding to 2 decimals follows the 3rd digit (art. 13). For OOD: convert total capital first, then allocate shares proportionally to the previous participation (art. 31(5)).

If the sum of shares differs slightly from capital due to rounding (within 5%), the law allows a simplified adjustment → application A4. Over 5% — general Commercial Act procedure.
