Registering an EU car in Bulgaria (2026): documents, steps and costs

If you moved to Bulgaria with your car or bought one in another EU country, it must be registered with KAT (the traffic police). With documents ready, it usually takes a day.

When you must register

• Bought abroad — within 30 days of the contract or invoice; late registration is fined.
• Moved with your own car — once you live in Bulgaria permanently, re-register. The exact deadline for foreign residents is less clear-cut than the 30 days for Bulgarian citizens, so ask your local KAT and don't delay: fines for driving on foreign plates are significant.

Documents

1. The foreign registration certificate (both parts if issued).
2. The sales contract or invoice.
3. Bulgarian third-party insurance issued by VIN.
4. The eco fee declaration (Appendix 12) with proof of payment.
5. Your ID and LNCh.
6. A notarised power of attorney if someone registers for you.

Steps

1. Insurance first — KAT will not start without it.
2. Pay the eco fee at an authorised office, usually near KAT.
3. Apply at KAT; the car is checked on site (VIN and engine).
4. Pay the fee, preferably by card.
5. Receive plates and the registration certificate; the car is added to your local tax record automatically.

After registration

• Annual roadworthiness test.
• Annual local vehicle tax, paid to the municipality (discount if paid by 30 April).
• An e-vignette for most intercity roads (bgtoll.bg).
• EU driving licences are valid without exchange; non-EU licences usually need exchanging after you get residence.
