Types of Business Entities Available in Bulgaria: Choosing the Right Structure

Introduction

Bulgaria has become an increasingly attractive jurisdiction for company formation in Europe thanks to its low corporate tax rate, EU membership, competitive labor costs, and strategic location at the crossroads of Southeast Europe. Choosing the right corporate structure is a critical first step for founders, investors, and foreign companies planning to enter the Bulgarian market. This article explains the main types of business entities available in Bulgaria, compares their legal and tax features, and outlines practical requirements, costs, timelines, and documentation needed for business registration.

Why Bulgaria is attractive for business

• Competitive taxation: Bulgaria applies a flat corporate tax rate of 10%, one of the lowest in the EU, which is a key incentive for investors seeking efficient tax planning within an EU framework.
• EU access and double tax treaty network: As an EU member state, companies registered in Bulgaria have access to the single market and benefit from EU regulations and the country’s network of bilateral tax treaties.
• Low operating costs: Labor and office costs are generally lower than in Western Europe, improving operating margins for many businesses.
• Skilled workforce and growing tech ecosystem: Bulgaria has expanding IT and services sectors, making it attractive for outsourcing, software development, and shared services.
• Predictable legal framework: Bulgarian company law is aligned with EU practices and administered through the Commercial Register and the Commercial Register Gazette.

Overview of common company types

Limited Liability Company (OOD / EOOD)

• Description: The most common corporate structure for local and foreign entrepreneurs. OOD (Обикновено дружество с ограничена отговорност) is a multi-member limited liability company; EOOD (Еднолично дружество с ограничена отговорност) is a single-member variant.
• Liability: Members’ liability limited to their contributions.
• Minimum share capital: Very low — the statutory minimum is nominal (2 BGN), making it ideal for small and medium enterprises.
• Governance: Managed by one or more managers; shareholder meetings control major decisions.
• Suitability: SMEs, startups, subsidiaries, trading and service activities.

Joint-Stock Company (AD)

• Description: A corporation structured for larger capital needs and public offerings (open or closed). Known as Акционерно дружество (AD).
• Liability: Shareholders’ liability limited to their share capital.
• Minimum share capital: Substantially higher (commonly 50,000 BGN); suited for larger ventures.
• Governance: More formal governance with a board of directors and statutory auditors in some cases.
• Suitability: Large projects, companies seeking to raise capital through selling shares or preparing for public listing.

Branch and Representative Office

• Branch (клон): Not a separate legal entity; it is an extension of a foreign company and can perform commercial activities in Bulgaria.
• Representative office (представителство): Limited to non-commercial activities (market research, promotion) and cannot enter into commercial contracts on its own.
• Liability: For branches, the foreign parent company is fully liable for branch obligations.
• Suitability: Foreign companies testing the market, carrying out contracts via a local presence, or establishing a foothold before creating a subsidiary.

Sole Trader / Sole Proprietor (ET)

• Description: Natural person registered as a commercial trader (Едноличен търговец).
• Liability: Unlimited personal liability for business debts.
• Suitability: Micro-businesses, freelancers, and sole practitioners.

Partnerships (General and Limited Partnerships)

• General partnership (SD) and limited partnership (KD) exist under Bulgarian law.
• Liability: In a general partnership, partners have joint and several liability; in limited partnerships, limited partners’ liability is restricted while general partners retain full liability.
• Suitability: Professional services, family businesses, or collaborations where partners are comfortable with shared liability.

Cooperative and European Company (SE)

• Cooperatives: Member-owned entities used in agriculture, crafts, and mutual enterprises.
• SE (Societas Europaea): For larger cross-border reorganizations; allowed under EU regulations but less commonly used.

Key factors in choosing the right corporate structure

• Liability exposure: If limiting personal liability is a priority, an OOD/EOOD or AD is preferable.
• Capital needs: For substantial capital or planned public offering, an AD is better suited.
• Governance and compliance: ADs have stricter formalities, while OODs are more flexible.
• Tax and reporting: Most trading and service entities are subject to the same corporate tax (10%) but differ in accounting and disclosure requirements.
• Ease and speed of formation: OOD/EOOD and branches are faster and cheaper to establish than an AD.

Practical steps to form a company in Bulgaria

1. Choose and reserve a company name with the Commercial Register.
2. Prepare incorporation documents: Articles of Association (for OOD/AD) or decision of incorporation for single-member companies; statutory documents for partnerships.
3. Obtain a legal address in Bulgaria (registered office).
4. Appoint directors/managers and, where applicable, a supervisory board or statutory auditors.
5. Open a bank account and, if required by the chosen form, deposit share capital or evidence of subscription.
6. File incorporation package with the Bulgarian Commercial Register (Targovски Регистър) and the Registry Agency.
7. Obtain a Unified Identification Code (BULSTAT) and register for corporate tax with the National Revenue Agency (NRA).
8. Register for VAT if annual taxable turnover exceeds the threshold or if voluntarily registering (current threshold: 50,000 BGN).
9. Register employees with the National Social Security Institute (if hiring) and comply with labor and payroll obligations.

Documents typically required

• Notarized Articles of Association / Deed of Incorporation or equivalent.
• Founders’/shareholders’ identification documents (passports for foreign individuals; notarized and, if required, apostilled corporate documents for foreign legal entities).
• Proof of legal address (rental agreement or ownership document).
• Manager(s) and beneficial owner(s) details and declarations.
• Bank certificate of capital deposit or proof of subscription (where applicable).
• Specimen signatures, powers of attorney (if representatives are used).
• Application forms for the Commercial Register and tax authorities.

Note: Foreign documents often must be notarized, translated into Bulgarian by a certified translator, and in some cases, apostilled or legalized depending on origin.

Costs (approximate) and fees

• State registration fees: Vary by filing method; as a guideline, expect a range of approximately 100–250 BGN for company registration (exact fees depend on entity type and whether you use online filing).
• Notary and certified translation fees: Typically range from 50 to several hundred BGN depending on the number and nature of documents.
• Legal and consulting fees: Professional formation packages range widely — from 300–1,500 EUR for standard LLC setups, up to several thousand EUR for complex AD formations or foreign branch establishment.
• Bank fees and capital deposit: Banks may charge account opening fees or require minimum initial deposits; for OODs the statutory minimum capital is nominal (2 BGN), but practical banking requirements vary.
• Ongoing compliance costs: Accounting, audit (if applicable), payroll processing, and annual filing fees. Small OODs typically pay for accounting services (monthly) ranging from 100–500 EUR depending on activity and payroll.

All figures above are indicative and subject to change; costs will vary with service providers and the complexity of each case.

Timelines

Typical setup time for company formation in Bulgaria is around 4–6 weeks from start to finish. This timeline depends on:

• Completeness and correctness of the documentation.
• Whether foreign documents require apostille/legalization and translation.
• Bank processing time for opening accounts and capital deposits.
• Speed of appointments with notaries and public registers.

Filing electronically and working with an experienced local adviser can shorten the process; in straightforward cases, registration can sometimes be completed in 1–2 weeks.

Taxation and reporting highlights

• Corporate tax: Flat rate of 10% on taxable profits — competitive for EU jurisdictions.
• VAT: Standard VAT rate is 20%; registration threshold (compulsory) is 50,000 BGN of annual taxable turnover. Voluntary registration is possible.
• Withholding taxes and payroll: Bulgaria applies withholding taxes and social security contributions; employers must register and remit payroll taxes and social insurance contributions for employees.
• Accounting and audit: Companies must maintain statutory accounts under Bulgarian accounting standards; large companies meeting specific criteria require statutory audits.

Consult a tax advisor for specific tax planning and to understand implications of dividend distributions, transfer pricing rules, and cross-border tax treaties.

Common pitfalls and practical tips

• Legal address: Don’t overlook the need for a proper registered office; temporary or non-compliant addresses will delay registration.
• Beneficial ownership transparency: Bulgaria maintains registers for ultimate beneficial owners; ensure accurate disclosures to avoid fines.
• Banking requirements: Choose a bank experienced with company formation and foreign clients; banks will conduct KYC and may require additional documentation for non-resident founders.
• Local counsel: Using a Bulgarian notary and corporate lawyer expedites the process and ensures compliance with translation, apostille and other formal requirements.
• Licenses and permits: Regulated activities (financial services, healthcare, transportation, energy, food handling) require sector-specific licenses before commencement.

Conclusion

Selecting the right corporate structure in Bulgaria depends on your business goals, capital needs, liability preferences, and regulatory appetite. For most small and medium-sized ventures, an OOD/EOOD offers a flexible, fast, and cost-effective route to market; larger investments or public capital needs are better suited to an AD. Bulgaria’s low corporate tax rate (10%), EU membership, and favorable cost environment make it an attractive location for company formation, but careful planning is essential to navigate documentation, local formalities, and ongoing compliance. Typical setup time is 4–6 weeks, and partnering with local legal and accounting advisers will reduce delays and ensure a smooth business registration process.
