Euro 2026 Company Capital Compliance: Key Changes 2026
From the start of 2026, the Bulgarian lev will be replaced by the euro at the set rate of 1 EUR = 1.95583 BGN. All registered company capital—whether in a limited liability company (OOD/EOOD) or a joint-stock company (AD/EAD)—will be seamlessly recalculated based on this conversion rate. The authorities will handle the conversion automatically; you won’t need to pay any state fee, and shareholders’ ownership stakes will remain exactly as they were before. This transition is based on precise amendments to the Euro Introduction Act, ensuring legal continuity and clarity.
Your Next Steps: Updating Company Documents
While the initial currency conversion requires no application, every company must take action within twelve months after the euro enters circulation. The law requires all businesses to formally update their governing documents (such as the statutes and articles of association) to show the company capital in euros. The final date for submitting these revised documents to the Commercial Register is December 31, 2026. Missing this deadline could trigger penalties, including fines, and may block your ability to register changes like new shareholders or company activities.
Extra Context: Dual Circulation and Pricing
For a brief period in early 2026, both BGN and EUR can be used for cash transactions. Additionally, businesses will need to display “dual pricing” (showing prices in both currencies) starting August 8, 2025. This dual pricing will continue for a full year and is required for all sales and contracts to help consumers adjust smoothly to the new currency.
Document Preparation: How to Approach the Process
Companies filing amendments to corporate structure in 2026—such as changes in shareholding, company name, or activities—can bundle the euro capital update with these filings. For others with no planned changes, a standalone amendment must be filed. Notarization and registry procedures remain as usual, and it’s wise to engage an accounting or legal partner to navigate the specifics.
Official Information and Deadlines
All government and EU sources confirm that Bulgaria’s transition to the euro remains on track, with no announced delays as of October 2025. Both the European Central Bank and the Bulgarian Ministry of Finance have verified these requirements, so businesses can proceed with confidence that the published timeline and obligations are current and reliable.
Why Timely Action Matters
By updating company documents before the final deadline, businesses avoid disruptive administrative sanctions and ensure ongoing readiness for future adjustments. Acting ahead of the rush allows for careful review of ownership structures, internal protocols, and optimal compliance with Bulgaria’s integration into the eurozone.
