Bulgaria
EU's Lowest Flat Tax

Bulgaria is an EU member state in southeastern Europe, bordered by Romania, Serbia, North Macedonia, Greece, and Turkey, with a Black Sea coastline to the east. The capital, Sofia, is a city of 1.3 million people, situated at the foot of Vitosha Mountain. Bulgaria joined the European Union in 2007 and uses the Bulgarian lev, which is pegged to the euro at a fixed rate of BGN 1.95583 per euro. Bulgaria is expected to adopt the euro in 2026.

Bulgaria introduced a 10% flat income tax in 2008 — the lowest in the European Union — and has maintained it ever since. Corporate income tax is also 10%, the joint lowest in the EU alongside Cyprus. Dividends are taxed at 5%. The combination of EU membership, a flat tax system, and a cost of living that is among the lowest in Europe makes Bulgaria one of the most underrated tax-efficient jurisdictions in the world.

The country has a well-educated, English-speaking workforce, a growing tech sector centred on Sofia, and a quality of life that is often surprising to first-time visitors. The Rila and Pirin mountain ranges offer world-class skiing in winter, and the Black Sea coast provides a long summer season. Plovdiv, Bulgaria's second city, was European Capital of Culture in 2019 and has a thriving arts and restaurant scene.

What to be aware of

Bulgaria is not a zero-tax jurisdiction. The 10% flat rate is the lowest in the EU, but it is not zero. Social contributions are payable on employment income and can add significantly to the effective rate. VAT is 20%. The legal and bureaucratic system can be slow and opaque. Corruption remains a concern at institutional level, though it rarely affects the daily lives of foreign residents. The country is not yet in the Schengen Area, though accession is expected.

Sofia sits in a broad valley at 550 metres above sea level, with the Vitosha Mountain rising to 2,290 metres directly to the south of the city. On a clear day, the mountain is visible from almost anywhere in Sofia — a reminder that you are not in an ordinary European capital. The city has a slightly Soviet-era character in its wider districts, but the centre — particularly the area around the National Palace of Culture, Vitosha Boulevard, and the old town — has a genuine European quality, with good restaurants, cafés, and cultural institutions.

Plovdiv, 150 kilometres southeast of Sofia, is Bulgaria's most charming city. The old town, built on three hills above the Maritsa River, is a UNESCO World Heritage Site, with Roman ruins, Ottoman architecture, and Bulgarian National Revival houses. The city has a creative, cosmopolitan character that has grown significantly since its stint as European Capital of Culture.

The Black Sea coast stretches for 378 kilometres, from the Romanian border in the north to the Turkish border in the south. Varna and Burgas are the main coastal cities; the resort areas of Sunny Beach, Golden Sands, and Sozopol attract millions of tourists each summer. The sea is warm from June to September, and the beaches are long and well-maintained. Outside the peak tourist season, the coast is quiet and genuinely beautiful.

Vienna is 2 hours by plane. London is 3 hours. Istanbul is 1 hour. Bulgaria is well-connected to the rest of Europe, with Sofia Airport offering direct flights to most major European cities.

"Bulgaria is a fascinating, beautiful, difficult country, and I fell in love with it."

"Bulgaria, I reflected as I walked back to the hotel, is not a country; it's a near-death experience."

"Bulgaria is fascinating. Because it had been a Communist country until the mid-80s, so it had just recently transitioned. And there were still the police towers on the street corners."

Bulgaria's tax system is the most competitive in the European Union. For those who want a low-tax base within the EU — with full access to the single market, freedom of movement, and EU legal protections — Bulgaria is the most efficient option available.

• ›10% flat personal income tax — the lowest in the EU, applied uniformly to all income regardless of amount.
• ›10% flat corporate income tax — joint lowest in the EU alongside Cyprus.
• ›5% dividend tax — distributions from Bulgarian companies to individual shareholders are taxed at 5%.
• ›EU membership — full access to the EU single market, freedom of movement, and EU legal framework.
• ›Euro peg — the Bulgarian lev is pegged to the euro at a fixed rate, providing currency stability. Euro adoption expected in 2026.
• ›Extensive DTA network — Bulgaria has double tax agreements with over 70 countries, including all major EU states, the US, and the UK.
• ›Low cost of living — among the lowest in the EU, particularly outside Sofia.

Under Bulgarian law, an individual is considered a tax resident if they meet one of the following criteria:

• ›183-day rule: You spend more than 183 days in Bulgaria in any calendar year.
• ›Permanent address: You have a permanent address (registered domicile) in Bulgaria and your centre of vital interests is in Bulgaria.
• ›Centre of vital interests: Your personal and economic ties are stronger with Bulgaria than with any other country.

Bulgarian tax residents are taxed on their worldwide income at the flat 10% rate. Non-residents are taxed only on Bulgarian-source income. The key advantage of Bulgarian tax residency is the flat 10% rate on all income — employment, self-employment, dividends, interest, rental income, and capital gains are all taxed at the same rate.

Bulgaria has an extensive network of double tax agreements (DTAs) with over 70 countries, including all major EU member states, the United States, the United Kingdom, Switzerland, and most of Eastern Europe. This network is one of Bulgaria's most significant advantages over pure offshore jurisdictions — it allows Bulgarian residents to receive income from foreign sources with reduced withholding taxes at source.

Key DTAs include agreements with Germany (5%/15% dividend withholding), the United Kingdom (5%/10%), France (5%/15%), the United States (10%), Switzerland (5%/15%), and Austria (0%/5%). The specific rates depend on the type of income and the shareholding percentage. In each case, the Bulgarian resident pays the lower of the treaty rate and the Bulgarian domestic rate.

The DTA network makes Bulgaria particularly attractive for those with income flowing from multiple European countries — the combination of low domestic rates and treaty protection can result in a very low effective tax rate on foreign-source income.

Relocating to Bulgaria does not automatically end your tax obligations elsewhere. The critical question is whether you have genuinely severed tax residency in your country of origin — and this is determined not by where you have registered an address, but by where you actually live, where your ties are, and how your life is organised.

Most countries use a combination of objective tests to determine tax residency: the number of days you spend on their territory, where your family lives, where your habitual abode is, where your business is managed, and where your social and economic life is centred. If you spend more than 183 days in your home country, maintain a family home there, or continue to manage a business from there, you may remain fully tax resident — regardless of what your Bulgarian residence registration says.

A sham relocation — registering an address in Bulgaria while continuing to live, work, and maintain your life elsewhere — does not achieve tax freedom. It creates legal risk. We only work with clients who are serious about making a real move to Bulgaria.

Before you relocate to Bulgaria, you need to understand what tax consequences arise in your current country of residence at the point of departure. These rules vary significantly by country and must be assessed individually.

• ›Germany — Applies an exit tax on unrealised gains in shareholdings of 1% or more under §6 AStG. A ten-year look-back period can apply even after departure.
• ›United States — The expatriation tax under IRC §877A treats long-term residents and citizens as having sold all worldwide assets at fair market value on the day they relinquish citizenship or residency.
• ›France — Exit tax applies to unrealised gains on securities and company rights above €800,000 when a French tax resident relocates abroad.
• ›United Kingdom — Temporary non-residence rules: if you leave the UK and return within 5 years, certain income and gains realised during the absence are taxed on return.
• ›Austria — Exit tax applies to unrealised gains on business assets and shareholdings when an Austrian tax resident relocates to a non-EU/EEA country.

Bulgaria's 10% flat corporate income tax is the joint lowest in the EU. Setting up a Bulgarian company is straightforward and inexpensive. The main corporate structure is the OOD (Дружество с ограничена отговорност) — the Bulgarian equivalent of a limited liability company — which can be incorporated with a minimum share capital of BGN 2 (approximately €1).

• ›OOD (Limited Liability Company) — the standard structure for most businesses. 10% corporate income tax on profits. Dividends distributed to individual shareholders are subject to an additional 5% withholding tax.
• ›AD (Joint Stock Company) — used for larger businesses and those seeking external investment. More complex governance requirements.
• ›ET (Sole Trader) — for individual entrepreneurs. Income is taxed at 15% (with a 25% cost deduction, resulting in an effective rate of approximately 11.25%).
• ›Freelancer registration — self-employed individuals can register as freelancers and pay income tax at 10% on net income (after a 25% standard deduction).

The total tax burden on profits extracted as dividends from a Bulgarian OOD is approximately 14.5% (10% corporate tax + 5% dividend withholding on the remaining 90%). This is the lowest combined rate on business profits in the EU.

Bulgaria works well for a specific profile of person. It does not work for everyone.

Good fit for:

• ›EU citizens seeking the lowest tax rate within the EU — Bulgaria offers 10% flat tax with full EU rights, the most efficient combination available in the single market.
• ›Digital entrepreneurs and remote workers — low cost of living, good internet infrastructure, and a growing tech community in Sofia.
• ›Investors with European-source income — the DTA network allows Bulgarian residents to receive European dividends and interest with reduced withholding at source.
• ›Those who value EU membership — for those who want to remain within the EU legal and political framework while minimising tax, Bulgaria is the best option.

Poor fit for:

• ›Those seeking zero tax — Bulgaria's 10% rate is the lowest in the EU, but it is not zero. For zero tax, the Cayman Islands, UAE, or Monaco are more appropriate.
• ›Those with high employment income — social contributions on employment income can add significantly to the effective rate.
• ›Those who cannot genuinely relocate — Bulgaria requires real presence and real ties to work as a tax base.

EU and EEA nationals have the right to live in Bulgaria without a visa or residence permit for any length of time. Non-EU nationals have the following main options:

• ›D-Visa (Long-Stay Visa) — allows a stay of up to one year in Bulgaria. Can be obtained for various purposes including employment, business, study, or family reunification. Can be converted into a temporary residence permit.
• ›Temporary Residence Permit — granted for up to one year, renewable. Available for those who have established a company in Bulgaria, are employed in Bulgaria, or have other qualifying ties.
• ›Permanent Residence Permit — available after 5 years of continuous temporary residence in Bulgaria.
• ›Digital Nomad Visa — Bulgaria introduced a digital nomad visa in 2023, allowing remote workers to live in Bulgaria for up to one year.
• ›Investment Residence — non-EU nationals who invest BGN 1 million (approximately €500,000) in Bulgarian government bonds or BGN 2 million in a Bulgarian company can obtain permanent residence.

Bulgarian citizenship can be obtained by naturalisation after 5 years of continuous permanent residence in Bulgaria, provided the applicant demonstrates language proficiency, has no criminal record, and has renounced or is willing to renounce their previous citizenship (dual citizenship is not generally permitted under Bulgarian law, with some exceptions).

Bulgarian citizenship is an EU citizenship, granting the right to live and work in any EU member state, travel visa-free to over 180 countries, and access EU consular protection worldwide. For non-EU nationals, Bulgarian citizenship is one of the most accessible routes to EU citizenship, given the relatively short naturalisation period and the straightforward residence requirements.

Bulgaria also has an investment citizenship programme (though this has been under review following EU pressure), and citizenship by descent is available for those who can demonstrate Bulgarian ancestry.

Bulgaria has a well-developed banking sector, with a mix of domestic banks and subsidiaries of major European financial institutions. The Bulgarian National Bank (BNB) regulates the sector, and deposits are protected up to €100,000 under the EU deposit guarantee scheme. Opening a personal bank account as a Bulgarian resident is straightforward for most nationalities.

Major banks operating in Bulgaria include UniCredit Bulbank, DSK Bank, First Investment Bank (FIB), Raiffeisenbank Bulgaria, and OTP Bank Bulgaria. Most major banks offer online banking in English and international wire transfer services.

Bulgaria participates in the OECD Common Reporting Standard (CRS), and Bulgarian financial institutions are required to report account information for foreign tax residents to the relevant authorities. This is not a problem for genuine Bulgarian residents — it is a problem only for those who are using a Bulgarian address while actually residing elsewhere.

Beyond the tax advantages, Bulgaria has a number of qualities that make it a genuinely attractive place to live.

• ›Natural diversity: Mountains, Black Sea coast, river valleys, and plains — Bulgaria has more natural variety than most European countries of comparable size.
• ›Low cost of living: Among the lowest in the EU. A comfortable lifestyle in Sofia costs a fraction of what it would in Vienna, Paris, or London.
• ›EU membership: Full EU rights — freedom of movement, EU legal framework, and the right to live and work anywhere in the EU.
• ›Good food and wine: Bulgarian cuisine is underrated. The wine is excellent and inexpensive. The restaurant scene in Sofia and Plovdiv is genuinely good.
• ›Skiing: Bansko, Borovets, and Pamporovo are among the most affordable ski resorts in Europe, with reliable snow and well-developed infrastructure.
• ›Growing expat community: Sofia has a growing community of Western European and North American expats, particularly in the tech and finance sectors.

Bulgaria is one of the most affordable countries in the EU. The cost of living in Sofia is approximately 50–60% lower than in Vienna or Munich, and outside Sofia it is lower still.

• ›Rent (Sofia, 2-bed apartment, central): €600–€1,200/month
• ›Groceries: Approximately 40–50% cheaper than Western European prices
• ›Dining out: €10–€30 per person at a mid-range restaurant
• ›Healthcare: Private health insurance is recommended; costs are low by Western standards. The public health system is functional but basic.
• ›Comfortable lifestyle (couple, Sofia): €2,500–€4,500/month, excluding property costs

EU nationals can purchase real estate in Bulgaria without restriction. Non-EU nationals can purchase apartments freely, but purchasing land requires either a Bulgarian company or permanent residence. The process is relatively straightforward, and prices are among the lowest in the EU.

• ›Apartments (Sofia, central, 2-bed): €150,000–€350,000
• ›Black Sea coast (resort area, 2-bed): €60,000–€200,000
• ›Transfer tax: 2–3% of the purchase price (varies by municipality)
• ›Notary fees: Approximately 0.1–1.5% of the purchase price
• ›Annual property tax: 0.01–0.45% of the assessed value (very low)

Property prices in Bulgaria have been rising steadily, particularly in Sofia and the Black Sea coast, but remain very low by Western European standards. The rental yield on Sofia apartments is typically 5–7% gross.

Bulgaria is an increasingly popular retirement destination for Western Europeans, particularly British, German, and Dutch nationals. The combination of low cost of living, warm summers, EU membership, and a 10% flat tax on pension income makes it genuinely attractive for retirees with modest to substantial assets.

• ›Pension income: Taxed at 10% in Bulgaria. However, your source country may withhold tax at source — this depends on the type of pension and the applicable DTA.
• ›Healthcare: Private health insurance is recommended. The public health system is functional but can be slow. Private clinics in Sofia are of good quality and very affordable.
• ›EU rights: EU retirees can live in Bulgaria indefinitely without a residence permit.
• ›Cost of living: Very low. A comfortable retirement lifestyle in Bulgaria costs €2,000–€3,500/month for a couple.

The United States taxes its citizens on worldwide income regardless of where they live. Moving to Bulgaria does not end your US tax filing obligation.

The United States and Bulgaria have a bilateral income tax treaty (the US–Bulgaria DTA), which provides relief on certain categories of income including dividends, interest, and royalties. However, the treaty does not eliminate US worldwide taxation for US citizens — it primarily reduces withholding taxes at source and provides tie-breaker rules for dual residents. You should confirm your specific treaty position with a qualified US international tax adviser.

The Foreign Earned Income Exclusion (FEIE)

The more reliable tool for most Americans living in Bulgaria is the the Foreign Earned Income Exclusion (FEIE) under IRC Section 911. For tax year 2025, the exclusion allows you to exclude up to $130,000 of foreign earned income from US federal income tax. For tax year 2026, the limit rises to $132,900 per qualifying person, adjusted annually for inflation.

• ›Earned income only: The FEIE applies to wages, salaries, and self-employment income earned while your tax home is abroad. It does not cover passive income — dividends, interest, capital gains, pensions, or rental income remain taxable by the US (though you may claim a Foreign Tax Credit for any taxes paid locally).
• ›Qualification tests: You must meet either the Bona Fide Residence Test (being a bona fide resident of a foreign country for an uninterrupted period covering an entire tax year) or the Physical Presence Test (being physically present in a foreign country for at least 330 full days in any 12-month period).
• ›Self-employment tax still applies: The FEIE reduces income tax but does not eliminate US self-employment tax (15.3%) on net self-employment income. This is a significant cost for freelancers and sole traders.
• ›FBAR and FATCA reporting: Americans with foreign bank accounts exceeding $10,000 must file an FBAR annually. FATCA reporting thresholds apply to foreign financial assets. Bulgarian banks participate in CRS, and account information is exchanged internationally.

If you live in Bulgaria and are a genuine tax resident there, the OECD Common Reporting Standard (CRS) presents no problem. You are legally entitled to hold accounts abroad and receive capital income without Bulgarian tax above 10%. Your status as a Bulgarian resident will be known to your banks, and any information exchanged under CRS will simply confirm what you have already declared.

The CRS is a threat only to those who are not genuine residents of Bulgaria but are using a Bulgarian address to conceal income from their actual country of residence. For legitimate residents of Bulgaria, CRS is irrelevant — you are not evading taxes, you are simply living in a country that taxes you at 10%.

Beyond the tax and immigration steps, relocating to Bulgaria involves a number of practical formalities. These include deregistering from your home country's residents' register, notifying your home country's tax authority of your departure, closing or restructuring any business interests that could create continued tax nexus, and ensuring your financial accounts are correctly documented with your new Bulgarian address.

In Bulgaria, you will need to: obtain your residence registration (for non-EU nationals, a residence permit), open a Bulgarian bank account, register your address with the local municipality, and — if incorporating a company — complete the registration with the Bulgarian Commercial Register. We assist with coordinating all of these steps as part of our relocation service.

A move to Bulgaria is not complicated — but it requires proper planning. The tax advantages are real, but they only materialise if the relocation is executed correctly. We work with clients at every stage of the process, from the initial feasibility assessment through to the final deregistration from their home country.
