Bulgaria and the Euro: What Turkish Businesses Need to Know

On 1 January 2026, Bulgaria adopted the euro and became the 21st member of the euro area. For Turkish companies using Bulgaria as a base for European sales, distribution, production or services, the change is important—but not for the simplistic reason that currency risk suddenly disappeared.

The Bulgarian lev had already been fixed to the euro for many years at €1 = BGN 1.95583. The more practical change is that Bulgarian businesses now invoice, account, pay salaries and hold domestic bank balances directly in euro, without a separate national currency between them and most of their EU customers.

What changed on 1 January 2026?

The euro became Bulgaria’s official currency on 1 January. Following the one-month dual-circulation period, it has been the country’s sole legal tender since 1 February 2026.

The changeover had several immediate effects:

• Lev-denominated bank accounts were converted into euro automatically and without a conversion fee;
• Existing contracts and legal instruments remained valid, with lev amounts converted at the official fixed rate;
• Salaries, domestic electronic payments, accounting records and tax reporting moved to euro;
• ATMs and payment terminals began operating in euro;
• Bulgarian companies no longer need a lev-to-euro conversion when dealing with euro-area customers and suppliers.

This reduces administrative friction and the possibility of conversion or rounding errors. It does not remove the need to review contracts, price lists and accounting systems for operational accuracy.

Does the euro eliminate currency risk?

Not entirely.

The direct lev/euro conversion has disappeared, but a Turkish business may still earn revenue in euro while paying suppliers, salaries or other costs in Turkish lira. Changes in the EUR/TRY rate can therefore affect margins, working capital and pricing decisions.

Currency exposure may also arise when contracts are denominated in US dollars or another currency. A Bulgarian company should still decide:

• Which currency will be used in customer and supplier contracts;
• How long a quoted price will remain valid;
• Whether an exchange-rate adjustment clause is needed;
• How euro revenue will be matched against lira or dollar costs;
• Whether the business needs a formal treasury or hedging policy.

The euro creates a clearer and more stable operating base for EU business. It does not make international currency management unnecessary.

Practical advantages for Turkish businesses

Simpler EU pricing and invoicing

A Bulgarian company can quote and invoice directly in the currency used by most of its EU customers. This makes budgets and commercial comparisons easier and removes an unnecessary conversion step.

Cleaner payment and accounting processes

Domestic accounts, salaries, taxes and most EU-facing transactions can now be managed in the same currency. For companies with regular euro revenue and expenses, this can simplify reconciliation and cash-flow planning.

Easier comparison for investors and partners

Financial statements, operating costs and investment budgets are easier to compare with those of euro-area businesses. That can make internal group reporting and investment decisions more straightforward.

Reduced conversion costs—but no guarantee of financing

The removal of lev/euro conversion may reduce certain banking and administrative costs. Euro adoption does not, however, guarantee a bank account, credit approval or a lower interest rate. Banks continue to assess ownership, business activity, source of funds, collateral and risk.

Bulgaria’s tax rates did not increase

Euro adoption did not change the country’s principal tax rates. Bulgaria continues to apply:

• 10% corporate income tax on taxable profit;
• A general 10% personal income-tax rate for many categories of income;
• 5% tax on dividends paid to individuals, subject to the recipient’s status and applicable treaty rules;
• A standard 20% VAT rate.

The currency used for calculation, declaration and payment changed to euro; the underlying tax obligations did not disappear. VAT registration, payroll, accounting, annual reporting and other compliance requirements continue to apply.

The euro simplifies the currency framework. It does not replace sound tax and business planning.

What did not change for trade with Türkiye?

Bulgaria’s euro adoption did not remove the customs border between Türkiye and the EU. Goods entering Bulgaria from Türkiye may still require customs declarations, A.TR or origin documents, product-compliance checks and import-VAT treatment.

A Bulgarian company also continues to need:

• Proper contracts and invoicing between related Turkish and Bulgarian companies;
• Transfer-pricing support for intra-group transactions;
• VAT and EORI registrations where applicable;
• Sector-specific licences and product compliance;
• Accounting records and annual filings;
• Bank and anti-money-laundering documentation.

Euro adoption also does not automatically provide residence rights to a company owner or director.

A temporary requirement: dual display of consumer prices

Businesses offering goods or services to consumers in Bulgaria must generally continue displaying prices in both euro and lev until 8 August 2026. The two amounts must be clear, legible and presented without misleading the customer.

This obligation is temporary, but it remains relevant to retail, hospitality, e-commerce and other consumer-facing businesses during 2026.

A practical checklist for Turkish-owned Bulgarian companies

If you operate or plan to establish a Bulgarian company, review the following:

1. Contracts: Check old lev references, rounding provisions, price-adjustment clauses and payment instructions.
2. Invoices and price lists: Use euro consistently and maintain dual display where consumer law requires it.
3. Accounting and payroll: Confirm that software, templates and internal approvals operate correctly in euro.
4. Banking: Review account details, payment instructions, authorisations and cash-management procedures.
5. Budgets: Model EUR/TRY exposure instead of assuming that all currency risk has disappeared.
6. Group transactions: Review transfer pricing and the currency used between the Turkish and Bulgarian companies.
7. Customer communication: Explain clearly which entity is contracting, where VAT is charged and which currency applies.

Frequently asked questions

Do existing contracts need to be signed again?
Generally, no. Euro adoption did not invalidate existing contracts. Lev amounts were converted at the official rate. Contracts should still be reviewed for operational references, payment details or clauses that may need clarification.

Were lev bank accounts closed?
No. Lev-denominated accounts in Bulgarian banks were converted automatically and free of charge into euro accounts on 1 January 2026.

Can businesses still accept lev cash?
The dual-circulation period ended on 31 January 2026. Since 1 February, the euro has been the sole legal tender in Bulgaria.

Did euro adoption change the 10% corporate-tax rate?
No. The corporate-tax rate remains 10%.

Does operating in euro remove EUR/TRY risk?
No. A business with income in euro and costs or liabilities in Turkish lira remains exposed to movements in the exchange rate.
