Bulgarian Company Formation: Tax Residency Rules for Foreign Founders
Incorporating a Bulgarian company does not make you a Bulgarian tax resident. The company becomes a Bulgarian tax resident and pays corporate income tax at a flat rate, while your personal status is decided separately by your permanent address, the time you spend in Bulgaria and where your centre of vital interests lies. The two positions need to be planned and documented together, not assumed.
Company residency and personal residency are separate questions
The most common misunderstanding we encounter is that registering an EOOD (single-member limited liability company) or an OOD (multi-member limited liability company) somehow changes the founder's own tax status. It does not. A company registered in Bulgaria is a Bulgarian tax resident entity under the Corporate Income Tax Act, and that fact says nothing about where you personally are taxable.
The distinction governs how your dividends, any salary and your own home-country tax exposure are treated. A founder who lives abroad and a founder who lives in Sofia can own identical companies and face entirely different personal tax outcomes.
How Bulgaria determines individual tax residency
Under the Personal Income Tax Act, an individual is a Bulgarian tax resident if they have a permanent address in Bulgaria, or if they are present in the country for more than 183 days in any 12-month period. A person who meets neither can still be treated as resident if their centre of vital interests is in Bulgaria. The text of the law is available on the Lex.bg legal database, and the National Revenue Agency publishes guidance on its official website.
The centre of vital interests is a factual assessment, not a formality. The authorities look at:
- where your family lives;
- where you own or rent your main home;
- where your business and economic activity is concentrated;
- where you hold bank accounts, insurance and other personal ties.
Day counts are therefore only half the picture. Staying under 183 days does not protect you if your family and home are in Bulgaria, and a Bulgarian address does not become irrelevant simply because you travel frequently.
What Bulgarian tax residency means for your personal tax position
A Bulgarian tax resident is taxable on worldwide income, generally at a flat personal income tax rate. A non-resident is taxed only on Bulgarian-source income. Dividends distributed by a Bulgarian company to individual shareholders are subject to withholding tax, whether the shareholder is resident or not, subject to any treaty relief. Rates can change, so check the current figures with the National Revenue Agency before committing to a structure.
If you are a non-resident wondering what you will pay on dividends from your own company, Bulgarian withholding is the starting point, but your home country may also tax the same dividend. Social security contributions follow separate rules based on where you work and which social security system covers you, so tax residency alone does not settle them.
Interaction with your home country and double taxation treaties
You can be a tax resident of Bulgaria and another country at the same time under each country's domestic law. This is where double taxation agreements apply. Most Bulgarian treaties follow the OECD model tiebreaker, which resolves dual residency in sequence: permanent home, then centre of vital interests, then habitual abode, then nationality.
The more difficult question is often your home country's rules, not Bulgaria's. Some jurisdictions apply exit taxes, continue to treat emigrants as resident for a period, or use tests that are stricter than the treaty tiebreaker. Take advice from a tax adviser in your home country before you relocate, not after.
Management and control: avoiding unintended residency issues for your company
A Bulgarian company run entirely from abroad can raise questions elsewhere. If you direct it from your home country, that country may argue the company has a permanent establishment there, or that its place of effective management is there. The reverse also applies: a foreign company managed from Bulgaria may become taxable in Bulgaria.
Where directors sit and where board decisions are actually made carry real weight. Record this deliberately:
- hold and minute board decisions in the jurisdiction you intend to be the centre of management;
- keep records of where meetings take place and who attends;
- avoid signing significant contracts from a location that undermines your stated position.
Substance, documentation and proving your residency position
Your stated position is only as strong as the evidence behind it. Useful documents include residence permits or registration certificates, tenancy or property documents, travel records, certificates of tax residency and board minutes.
For treaty relief, you may need a Bulgarian certificate of tax residency. This is requested from the National Revenue Agency, typically through the territorial directorate responsible for your address, with supporting evidence of residency. Forms and procedures change, so confirm the current process with the National Revenue Agency before relying on a timeline.
Common structuring scenarios for foreign founders
A non-resident founder acting as director from abroad
You remain a non-resident for Bulgarian purposes, taxed only on Bulgarian-source income, and dividends carry Bulgarian withholding tax. The main risk is management and control: if decisions are taken in your home country, expect scrutiny there.
A founder relocating to Bulgaria
Once you establish an address and ties, you become resident and taxable on worldwide income. Your home country's exit rules need attention, and the timing of your move affects both countries' positions.
A founder splitting time between countries
This is the most exposed situation. Day counts, home location and family ties can point in different directions, and treaty tiebreakers may decide the outcome. Keep detailed travel records from the first day.
Practical next steps before you incorporate
- Confirm your current tax residency in your home country.
- Estimate realistically how many days you will spend in Bulgaria.
- Decide who will manage the company and from where.
- Review the treaty position between Bulgaria and your home country.
- Proceed with registration once the structure is settled.
Professional tax advice becomes worthwhile at steps three and four, particularly if you plan to relocate or split your time.
