Complete Guide to Bulgaria Company Formation in 2026

Why EU founders are choosing Bulgaria in 2026

Bulgaria offers the lowest headline corporate tax in the European Union — a flat 10% — combined with full EU market access, a stable euro-pegged currency (BGN), and operating costs that remain a fraction of those in Western Europe. For founders looking to incorporate inside the EU without the overhead of Germany, France, or the Netherlands, Bulgaria company formation is one of the most efficient routes available.

Choosing the right legal form

Most EU founders incorporate as one of two limited-liability vehicles:

• OOD — a limited liability company with two or more shareholders
• EOOD — the single-shareholder version of the OOD

Both require only BGN 2 (~EUR 1) in minimum share capital, both shield personal assets, and both can be 100% foreign-owned. Larger ventures planning to raise institutional capital may instead opt for an AD (joint-stock company), which has a BGN 50,000 minimum capital.

The registration process, end to end

1. Reserve the company name at the Bulgarian Commercial Register
2. Draft articles of association in Bulgarian (a sworn translator is required for foreign founders)
3. Open an accumulation account at a Bulgarian bank and deposit the share capital
4. Notarise specimen signatures of the managing director
5. File the A4 application with the Commercial Register — decision typically within 3 working days
6. Receive your UIC (unified identification code) and convert the accumulation account into an operating account

Total elapsed time for a well-prepared file: 5 to 10 working days.

Typical costs

Item	Cost (EUR)
State fees	~75
Notary & translations	150-300
Registered office (year 1)	200-600
Optional incorporation service	400-900

After incorporation: what you must do

• Register with the National Revenue Agency (NRA) within 7 days
• Appoint a licensed accountant — monthly bookkeeping is mandatory
• Register for VAT if turnover will exceed BGN 100,000 (~EUR 51,130) in 12 months, or voluntarily from day one for B2B EU trade
• File annual financial statements with the Commercial Register by 30 September

Bottom line

A Bulgarian OOD or EOOD gives EU founders a clean, low-tax, fully compliant base inside the single market — usually live and invoicing within two weeks of decision. Pair it with a real accountant from day one and the structure runs itself.
