Company in Bulgaria: Key Issues, Registration and Business Operations

Bulgaria offers one of the European Union's most accessible and cost-efficient environments for company formation, combining a flat 10% corporate income tax rate with straightforward registration procedures and full EU market access. Foreign entrepreneurs and holding structures regularly use Bulgarian entities as operational bases, regional hubs, or intermediate vehicles within broader international structures. Understanding the legal framework - from entity selection and registration mechanics to ongoing compliance obligations - is essential before committing capital or contractual obligations to a Bulgarian vehicle. This article covers the full lifecycle: entity types, registration procedure, corporate governance requirements, tax and accounting obligations, operational risks, and exit or restructuring options.

Bulgarian commercial law, governed primarily by the Commercial Act (Търговски закон, 'TA'), recognises several forms of legal entity. The two most relevant for international investors are the limited liability company (Дружество с ограничена отговорност, 'OOD') and the joint-stock company (Акционерно дружество, 'AD').

The OOD is the dominant vehicle for small and medium-sized operations. It requires a minimum share capital of BGN 2 (approximately EUR 1), though in practice a nominal capital of BGN 100-500 is standard. Liability is limited to the contributed capital, and the structure allows one or more founders, including foreign legal entities and individuals. The OOD is governed by a manager (управител) rather than a board, which simplifies day-to-day decision-making and reduces administrative overhead.

The AD is suited to larger operations, joint ventures, or structures requiring share transferability and investor participation. It requires a minimum share capital of BGN 50,000, with at least 25% paid up at incorporation. The AD must have a board of directors (едностепенна система) or a supervisory and management board (двустепенна система), adding governance complexity but also credibility with institutional counterparties.

A sole trader (Едноличен търговец, 'ET') is available to individuals but carries unlimited personal liability - making it unsuitable for most international business purposes. A branch (клон) of a foreign company is another option: it is not a separate legal entity, and the parent bears full liability for its obligations. Branches are useful for market-testing or project-specific activity but create direct exposure for the foreign parent.

A common mistake among international clients is defaulting to the branch structure to avoid a separate legal entity, without appreciating that Bulgarian courts and counterparties treat the parent as directly liable for all branch obligations. For most operational purposes, an OOD provides better liability insulation at minimal additional cost.

Company registration in Bulgaria is handled by the Commercial Register and Register of Non-Profit Legal Entities (Търговски регистър и регистър на юридическите лица с нестопанска цел), administered by the Registry Agency (Агенция по вписванията). Registration is conducted electronically through the Agency's online portal, though notarised documents remain required for certain filings.

The standard registration process for an OOD involves the following steps:

• Drafting and notarising the articles of association (учредителен акт) before a Bulgarian notary.
• Opening a bank account and depositing the share capital, obtaining a bank certificate confirming the deposit.
• Preparing the application package, including declarations of consent and specimen signatures from the manager.
• Submitting the application electronically or in person to the Registry Agency.
• Receiving the unique identification number (ЕИК) upon successful registration.

The Registry Agency is required to process complete applications within three business days under Article 19 of the Commercial Register Act (Закон за търговския регистър и регистъра на юридическите лица с нестопанска цел). In practice, straightforward OOD registrations are often completed within one to two business days when submitted electronically with a complete package. Incomplete submissions trigger a correction notice, and the applicant has three business days to remedy deficiencies; failure to do so results in rejection, requiring a fresh application.

State registration fees are modest by EU standards, and total out-of-pocket costs for a standard OOD registration - including notarial fees, bank account opening, and state duties - typically fall in the low hundreds of EUR. Legal fees for professional assistance start from the low thousands of EUR depending on the complexity of the structure and the need for translated or apostilled foreign documents.

Foreign founders must present notarised and apostilled (or legalised) corporate documents from their home jurisdiction, translated into Bulgarian by a certified translator. This step is frequently underestimated: obtaining apostilled extracts from foreign registries and arranging certified translations can add two to four weeks to the timeline. Planning for this in advance avoids delays in operational launch.

After registration, the company must register with the National Revenue Agency (Национална агенция за приходите, 'NRA') for tax purposes. VAT registration is mandatory once taxable turnover exceeds BGN 100,000 in the preceding 12 months; voluntary registration is available from day one and is advisable for companies engaged in B2B transactions or international trade.

Once registered, a Bulgarian OOD must maintain a functioning governance structure and meet a set of ongoing legal obligations under the Commercial Act and related legislation.

The manager (управител) is the key executive officer. The manager may be a Bulgarian or foreign national and need not be a resident. However, the manager's identity, address, and specimen signature must be registered in the Commercial Register. Any change of manager requires a new notarised declaration and registration within seven days under Article 15 of the Commercial Register Act - failure to register changes on time exposes the company to administrative fines and, more critically, creates uncertainty about the authority of persons acting on the company's behalf.

The general meeting of shareholders (общо събрание на съдружниците) is the supreme governing body of the OOD. It must meet at least once per year to approve the annual financial statements and the distribution of profit or coverage of losses. Resolutions on certain matters - including amendments to the articles of association, admission or exclusion of shareholders, and increases or reductions of share capital - require a qualified majority or unanimity as specified in the articles or the Commercial Act.

A non-obvious risk for foreign-owned OODs is the absence of a local shareholder or manager who can physically attend to urgent filings or sign documents. Many international structures appoint a nominee manager or a local representative for operational continuity. This arrangement requires careful contractual documentation to preserve actual control while ensuring legal compliance.

The company must maintain proper accounting records in accordance with the Accountancy Act (Закон за счетоводството). Companies meeting certain size thresholds are subject to mandatory statutory audit. Annual financial statements must be filed with the Registry Agency by 30 June of the following year. Failure to file triggers fines and, after a period of persistent non-compliance, can result in the company being struck off the register.

Beneficial ownership disclosure is a mandatory requirement under Bulgarian anti-money laundering legislation implementing the EU's Fourth and Fifth Anti-Money Laundering Directives. All companies must register their ultimate beneficial owners (UBOs) in the Central Register of Beneficial Owners (Централен регистър на действителните собственици), maintained by the Registry Agency. Failure to register UBOs or to update the register following ownership changes carries significant administrative penalties and can impede banking relationships.

Bulgaria's tax environment is one of the most competitive within the EU, and understanding its structure is central to the business case for using a Bulgarian entity.

Corporate income tax is levied at a flat rate of 10% on taxable profit under the Corporate Income Tax Act (Закон за корпоративното подоходно облагане, 'CITA'). This applies to Bulgarian-resident companies on their worldwide income. The tax year coincides with the calendar year, and advance tax instalments are due monthly or quarterly depending on the company's prior-year revenue. The annual corporate tax return must be filed by 31 March of the following year.

Dividend distributions to foreign shareholders are subject to withholding tax at 5% under Article 194 of the CITA, unless a lower rate applies under a double tax treaty. Bulgaria has an extensive network of double tax treaties - covering most EU member states and many non-EU jurisdictions - which frequently reduce or eliminate withholding on dividends, interest, and royalties. Distributions to EU/EEA parent companies meeting the conditions of the EU Parent-Subsidiary Directive are exempt from withholding tax entirely.

Value added tax is governed by the VAT Act (Закон за данък върху добавената стойност). The standard VAT rate is 20%. Intra-EU supplies and exports are zero-rated, and the reverse charge mechanism applies to B2B services received from abroad. VAT returns and payments are due monthly for most registered businesses.

Transfer pricing is an area of increasing scrutiny by the NRA. Bulgarian transfer pricing rules, set out in the CITA and supplemented by NRA guidance, require that transactions between related parties be conducted at arm's length. Companies with significant intercompany transactions - management fees, loans, IP licences - should maintain contemporaneous transfer pricing documentation. The NRA has intensified audits of intercompany arrangements, particularly in structures where the Bulgarian entity generates thin margins.

A common mistake is treating the Bulgarian entity as a pure cost centre or conduit without substance, which creates both transfer pricing risk and potential challenges to treaty benefits. The NRA and Bulgarian courts have applied substance-over-form analysis in cases involving artificial arrangements, and the OECD BEPS framework has been progressively incorporated into Bulgarian practice.

Personal income tax on employment income is also levied at a flat rate of 10% under the Personal Income Tax Act (Закон за данъците върху доходите на физическите лица). Social security contributions add a significant additional cost to employment, and employers must register employment contracts with the NRA before the employee commences work - a procedural requirement that is frequently overlooked by foreign-managed companies.

Operating a company in Bulgaria involves a set of legal risks that differ in character from those in Western European jurisdictions, and international managers benefit from understanding them in advance.

Contractual disputes in Bulgaria are resolved by the civil courts or, where agreed, by arbitration. The general civil courts (районен съд, окръжен съд) have jurisdiction over commercial disputes, with the Sofia City Court (Софийски градски съд) handling larger commercial matters as a first-instance court. The Arbitration Court at the Bulgarian Chamber of Commerce and Industry (Арбитражен съд при БТПП) is a well-established domestic arbitral institution and is frequently chosen for disputes between Bulgarian and foreign parties. International arbitration under ICC, LCIA, or UNCITRAL rules is also available and enforceable in Bulgaria as a signatory to the New York Convention.

Enforcement of judgments and arbitral awards in Bulgaria follows the standard EU framework for EU judgments (Brussels I Recast Regulation) and the New York Convention for foreign arbitral awards. Enforcement proceedings are conducted through bailiffs (частни и държавни съдебни изпълнители), and the practical timeline from obtaining a judgment to recovering funds can range from several months to over a year depending on the debtor's asset position.

Debt recovery is a practical concern for companies extending credit to Bulgarian counterparties. The Civil Procedure Code (Граждански процесуален кодекс, 'CPC') provides for an order for payment procedure (заповедно производство) under Articles 410-425, which allows a creditor to obtain an enforceable order without a full trial if the debt is undisputed. This procedure is significantly faster than ordinary litigation - an order can be obtained within days - but the debtor has the right to object within two weeks, triggering full proceedings. For disputed debts, ordinary commercial litigation at first instance typically takes six to eighteen months.

Three practical scenarios illustrate the range of disputes that arise:

• A foreign shareholder discovers that the local manager has entered into contracts on behalf of the company without authorisation. Under the Commercial Act, the manager's authority to bind the company is broad and third parties acting in good faith are generally protected. The shareholder's remedy lies in an internal claim against the manager for breach of fiduciary duty, not in invalidating the contracts.

• A Bulgarian OOD with a single foreign shareholder fails to file annual financial statements for two consecutive years. The Registry Agency initiates proceedings to strike the company from the register. Reinstatement is possible but requires remedying all outstanding filings, paying accumulated fines, and submitting a reinstatement application - a process that can take several months and incur costs in the low thousands of EUR.

• A foreign company operating through a Bulgarian branch is audited by the NRA, which challenges the allocation of costs between the branch and the parent. The NRA issues a tax assessment for additional corporate tax and interest. The company has 14 days to appeal to the NRA's internal review body, and a further right of appeal to the Administrative Court (Административен съд) within 14 days of the internal decision.

A non-obvious risk in Bulgarian practice is the interaction between corporate and insolvency law when a company becomes insolvent. Under Article 626 of the Commercial Act, the manager is obliged to file for insolvency within 30 days of the onset of insolvency or over-indebtedness. Failure to file on time exposes the manager to personal liability for creditor losses arising from the delay. Foreign managers of Bulgarian subsidiaries are often unaware of this obligation and the personal exposure it creates.

International investors periodically need to restructure their Bulgarian operations - whether through share transfers, mergers, demergers, or liquidation. Each route has distinct legal, tax, and procedural implications.

Share transfer in an OOD is governed by Articles 129-130 of the Commercial Act. Transfers to third parties (non-shareholders) require a notarised share transfer agreement and a resolution of the general meeting approving the transfer. The transfer must be registered in the Commercial Register within seven days of the resolution. Transfer to an existing shareholder does not require general meeting approval unless the articles provide otherwise. The notarisation requirement adds cost and a short delay but provides legal certainty.

Mergers and demergers of Bulgarian companies are regulated by Articles 261-265 of the Commercial Act and, for cross-border mergers within the EU, by the implementing legislation transposing the EU Cross-Border Mergers Directive. A cross-border merger involving a Bulgarian entity requires approval from the Registry Agency, publication of merger terms, a creditor protection period of at least one month, and court confirmation in certain cases. The full process typically takes three to six months.

Liquidation of a Bulgarian OOD is initiated by a resolution of the general meeting and the appointment of a liquidator. The liquidator must publish a notice to creditors in the Commercial Register, and creditors have at least six months to submit claims. After settling all liabilities and distributing remaining assets, the liquidator files for deregistration. The minimum timeline for a clean liquidation is approximately seven to nine months; companies with outstanding tax liabilities or disputes face longer timelines.

A voluntary liquidation that is not preceded by proper tax clearance from the NRA is a frequent source of complications. The NRA conducts a tax audit of the company's affairs for the liquidation period, and any outstanding assessments must be resolved before deregistration is possible. Engaging tax advisers at the outset of the liquidation process avoids costly delays.

For holding structures, Bulgaria's participation exemption - exempting dividends received from EU/EEA subsidiaries from corporate income tax under Article 27 of the CITA - makes Bulgarian holding companies attractive as intermediate vehicles. However, the NRA scrutinises holding structures for substance, and a Bulgarian holding company that lacks genuine economic activity, local management, and decision-making capacity may be challenged as lacking the right to treaty or directive benefits.

The risk of inaction on compliance matters compounds over time. A company that neglects UBO registration, annual filings, or tax registration for even one to two years accumulates fines, potential criminal liability for managers, and reputational damage with banks and counterparties that is difficult to reverse quickly.

What are the main risks of appointing a foreign national as the sole manager of a Bulgarian OOD?

A foreign manager can legally hold this role without Bulgarian residency, but practical risks arise from the need to sign notarised documents in Bulgaria or before a Bulgarian consulate abroad. Urgent filings - such as changes to the register or responses to NRA requests - may be delayed if the manager is not physically accessible. Additionally, the manager bears personal liability for failure to file for insolvency within the statutory 30-day window if the company becomes insolvent. Many structures mitigate this by appointing a local co-manager or granting a limited power of attorney to a local representative for administrative matters.

How long does it realistically take to register a company in Bulgaria and begin operations?

For a Bulgarian-resident founder with documents ready, registration can be completed in three to five business days. For a foreign corporate founder, the realistic timeline is three to five weeks, accounting for obtaining apostilled corporate documents, certified translations, and notarisation. VAT registration, if pursued voluntarily from the outset, adds a further two to four weeks. Opening a corporate bank account - increasingly subject to enhanced due diligence by Bulgarian banks - can take two to six weeks depending on the bank and the complexity of the ownership structure. The total time from decision to operational readiness is typically six to ten weeks for a straightforward foreign-owned OOD.

When is it better to use a Bulgarian branch rather than a separate OOD?

A branch is preferable when the foreign parent wants to test the Bulgarian market without committing to a permanent structure, or when the activity is project-specific and time-limited. It avoids the cost and formality of a separate legal entity and simplifies intra-group accounting. However, the parent bears unlimited liability for branch obligations, and the branch cannot independently hold assets, enter into employment contracts as a separate employer, or benefit from Bulgaria's double tax treaties in its own right. For any activity involving significant contractual exposure, third-party credit, or long-term operations, an OOD provides materially better legal and financial protection.

Bulgaria presents a genuinely competitive environment for company formation and business operations within the EU - combining low corporate tax, accessible registration procedures, and a functional legal framework aligned with EU standards. The principal challenges for international investors are not structural but operational: maintaining compliance with ongoing filing obligations, managing the substance requirements for tax and treaty purposes, and navigating the practical realities of enforcement and dispute resolution. A well-structured Bulgarian entity, properly maintained, delivers significant advantages; a neglected one accumulates liabilities that are disproportionately costly to unwind.
