Euro Adoption in Bulgaria

Euro Adoption in Bulgaria

One of the most attractive question from the foreign customers is the question for Euro Adoption in Bulgaria.

From 1 January 2026, Bulgaria will officially adopt the euro (EUR) as its sole legal tender, replacing the Bulgarian lev (BGN) at the fixed and irrevocable conversion rate of 1 EUR = 1.95583 BGN.

This step follows the formal decision of the Council of the European Union on 8 July 2025, admitting Bulgaria into the euro area.

The transition to the euro is not simply a financial reform. It impacts every layer of the Bulgarian economy, from business contracts and taxation to accounting rules, consumer protection, and civil law relations.

For companies, professionals, and private citizens, this change requires preparation and compliance with a detailed legal framework.

This guide explains the rules, obligations, and timelines governing the adoption of the euro in Bulgaria, focusing on legal and practical aspects relevant to businesses, taxpayers, and consumers.

1. Key Dates for the Transition

• 8 July 2025 – EU Council decision admitting Bulgaria into the euro area.

• 8 August 2025 – Start of dual pricing (all prices shown in both BGN and EUR).

• 1 January 2026 – Euro Day: the euro becomes the sole official currency. All payments, contracts, and transactions must use the euro.

• 1–31 January 2026 – Parallel circulation: both leva and euros are legal tender. Change must be returned only in euros.

• 31 December 2026 – End of mandatory dual pricing. From 2027, prices are shown exclusively in euros.

2. Guiding Principles

Bulgaria’s Law on the Introduction of the Euro (LEI) establishes key principles:

• Consumer protection – Conversion must not disadvantage consumers or lead to artificial price increases.

• Efficiency and cost-effectiveness – The transition must minimize costs for businesses and the state.

• Clarity – Citizens must receive accessible and accurate information about the conversion process.

• Transparency – Authorities must ensure openness and accountability throughout the transition.

• Continuity – Contracts, debts, and obligations in leva remain valid. They are automatically converted into euros at the fixed rate.

3. Conversion and Rounding Rules

• Conversion rule (Art. 12 LEI): All amounts in BGN are divided by 1.95583. No alternative rates are allowed.

• Rounding rule (Art. 13 LEI): Results are rounded to the nearest cent.

  • If the third decimal < 5 → round down.

  • If the third decimal ≥ 5 → round up.

4. Payment Rules During Transition

• Between 1–31 January 2026, both leva and euros may be used.

• Merchants must return change only in euros (except if no euros are available). Mixed change (partly in leva, partly in euros) is prohibited.

• Companies must account for both currencies during this month, recording all final balances in euros.

• The Bulgarian National Bank (BNB) will exchange leva indefinitely, free of charge.

5. Impact on Businesses

5.1. Company Registration

• No need for re-registration. Company name, UIC, and Commercial Register entries remain unchanged.

• Internal documents and statutes must be updated within 12 months of Euro Day.

5.2. Bank Accounts

• Automatically converted to euros without fees or commissions.

• IBANs remain unchanged, only the currency switches.

• If companies hold both BGN and EUR accounts, one may be closed after Euro Day to reduce banking fees.

5.3. Company Capital

• With Bulgaria’s accession to the Eurozone on 1 January 2026, all companies registered in the Bulgarian Commercial Register must take specific legal steps to ensure compliance.

  NO Automatic Conversion of Capital !!!!

  • The registered capital of every company will be NOT automatically converted from Bulgarian lev (BGN) into euros (EUR) at the fixed exchange rate of papers in the Registry Agency in BULGARIA.

  • Usually the company with a capital of 5,000 BGN will have it converted into 2,556.46 EUR, but the company contract needs to be amended later.

  Adjustment of Shareholder Shares

  • In limited liability companies (LLCs / OOD), the individual shareholder contributions and shares will also be automatically converted into euros.

  • In cases where rounding differences appear after conversion, companies are permitted to adjust their capital. Such adjustments may not exceed 5% of the registered capital.

  • These changes may be made using a simplified legal procedure introduced specifically for the euro transition.

  Mandatory Amendments to Company Contracts

  • Despite the automatic conversion, all company owners are obliged to amend their company contracts (articles of association) to reflect the capital expressed in euros.

  • The amended company contracts must be filed and recorded in the Bulgarian Commercial Register.

  • Failure to update the contract may lead to inconsistencies in official records and potential difficulties in future corporate or commercial transactions.

  Practical Implications

  • Company owners should initiate the preparation of updated contracts immediately after 1 January 2026.

  • The documentation must include the new euro-denominated capital and the proportion of shareholder shares.

  • Legal assistance is strongly recommended to ensure compliance with the Commercial Act and the requirements of the Registry Agency.

Accounting and Financial Reporting

• Annual financial statements for 2026 and beyond must be in Euros.

• Comparative data from 2025 (in BGN) must be converted and disclosed.

• Gains and losses from conversion are recorded in the income statement.

Tax and Insurance Contributions

• From 1 January 2026, all taxes, social contributions, and declarations must be filed in euros.

• VAT registration numbers remain valid.

• VAT thresholds are converted: 100,000 BGN = 51,129.19 EUR (may later be simplified to 50,000 EUR).

• VAT returns covering December 2025/January 2026 must account for both currencies.

Dual Pricing 

From 8 August 2025 to 31 December 2026, all goods and services must show prices in both BGN and EUR:

• Prices must be displayed side by side, equally legible, without misleading information.

• Applies to labels, menus, catalogues, websites, and advertising.

• Receipts must show amounts in both currencies until 31 January 2026.

• Certain goods (e.g., tobacco products, fuel price boards, taximeters) are exempt.

The Effects on Individuals

• Cash payments: During January 2026, both leva and euros are accepted. From February, only euros.

• Bank exchanges:

  • BNB will exchange leva without limit and without time restriction.

  • Commercial banks and Bulgarian Post will exchange limited amounts for free during the first six months.

• Loans and wages: Automatically converted at the official rate. Special rounding applies to salaries, pensions, and social benefits.

• Savings: Deposits are converted automatically without loss of value.

Our practical recommendations

• Do not rush to exchange cash before Euro Day. Bank accounts are converted automatically.

• Update contracts, invoices, and accounting systems by the end of 2025 to avoid administrative issues.

• Prepare staff training for handling dual pricing, issuing receipts, and managing customer questions.

• Check IT systems and cash registers to ensure compliance with reporting requirements.

• Monitor official updates from the Ministry of Finance and the Bulgarian National Bank, as further instructions may be issued.

The adoption of the euro in Bulgaria is a historic milestone with wide-ranging implications for businesses, legal relations, and private citizens.

While the legal framework ensures continuity and protection, companies and individuals must prepare actively for the transition.

With early planning and proper adaptation, the shift to the euro will not only ensure compliance but also strengthen Bulgaria’s integration into the European economy, creating long-term benefits for trade, investment, and financial stability.
