On January 1, 2026, Bulgaria will officially join the Eurozone, marking a significant milestone in its economic integration with the European Union. The Bulgarian lev (BGN) will be replaced by the euro (EUR), with a fixed conversion rate of 1 EUR = 1.95583 BGN, ensuring stability and predictability during the transition.
Key Practical Points for Businesses
1. Dual Pricing
From August 2025 until December 2026, all businesses will be required to display prices in both BGN and EUR. This measure aims to help consumers adapt smoothly to the new currency.
2. Dual Circulation
For one month after adoption, both currencies will be legal tender. After this period, only the euro will remain in circulation.
3. Accounting & Payroll
- All contracts, invoices, and salary payments will automatically convert to EUR starting January 2026.
- ERP and accounting systems must be updated well before the deadline to avoid operational disruptions.
4. VAT Reporting
- Tax returns for periods ending in December 2025 will remain in BGN.
- From January 2026 onward, all filings must be in EUR.
Compliance and Penalties
Failure to comply with dual pricing rules can result in fines of up to EUR 511,000. Businesses should start preparing now to ensure a seamless transition and avoid costly penalties.
What Should Companies Do Now?
- Begin updating pricing systems and accounting software.
- Train staff on new procedures.
- Communicate clearly with customers about the upcoming changes.
The adoption of the euro is more than a currency change—it’s a strategic step toward deeper economic integration and stability. While the transition requires careful planning, early preparation will minimize risks and ensure compliance. For businesses, this is the time to act: update systems, educate teams, and embrace the opportunities that come with joining the Eurozone.
