Bulgaria
Europe'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 adopted the euro on 1 January 2026 at the fixed conversion rate of 1 EUR = 1.95583 BGN, becoming the 21st member of the Eurozone and eliminating the BGN/EUR currency risk that previously affected cross-border investors and businesses.

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.

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 adopted the euro on 1 January 2026, completing its transition from candidate to full Eurozone member at the fixed conversion rate of 1 EUR = 1.95583 BGN. The country retains the simplest tax structure in the EU — a 10% flat rate on both personal and corporate income, a 5% dividend tax, and no progressive brackets. Headline rates are unchanged for 2026, though several technical updates apply: cryptocurrency is now expressly within the taxable financial assets list, bank deposit interest dropped from 10% to 8%, and Pillar Two introduces a 15% domestic minimum top-up tax for MNEs with revenues of €750M or more.

• ›10% flat personal income tax — the lowest top rate in the EU alongside Romania. The same rate applies to all earned income with no progressive brackets, and to capital gains realised by Bulgarian tax residents.
• ›10% flat corporate income tax — also among the lowest in the EU. The OECD Pillar Two 15% domestic minimum top-up tax applies only to multinational groups with annual global revenues of €750 million or more in two of the last four years; ordinary trading companies and SMEs are not affected.
• ›5% dividend tax — for distributions to individuals from Bulgarian companies (a proposal to raise this to 10% was discussed but not adopted). Dividends from EU/EEA subsidiaries received by a Bulgarian holding company are generally exempt under the participation exemption.
• ›0% capital gains on listed securities — gains from the sale of shares of public companies on the Bulgarian Stock Exchange or on EU/EEA regulated markets are exempt; from 1 January 2026 the SME growth markets exemption (previously temporary since 2021) became permanent.
• ›Capital gains exemption on real estate — one residential property per year held for more than 3 years, plus up to two other properties held for more than 5 years, can be sold tax-free for individuals.
• ›0% wealth tax, 0% inheritance tax for direct family, 0% gift tax for spouses and direct relatives — Bulgaria has no wealth tax, and inheritance and gift taxes do not apply to transfers between spouses, parents and children.
• ›Cryptocurrency clarified from 2026 — virtual currencies are expressly within the taxable financial assets list from 1 January 2026, taxed at 10% with a 10% statutory deduction allowance for investment-related costs.
• ›70+ double tax treaties including with all major EU economies, the US, UK, Canada, China, and most G20 countries.
• ›Eurozone member from 1 January 2026 — Bulgaria adopted the euro at the fixed rate of 1 EUR = 1.95583 BGN, eliminating currency conversion friction with EU trading partners and bringing all tax filings into euro-denominated reporting.

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.

Is a local company always the right answer?

Not necessarily. For many internationally mobile entrepreneurs, the local company is not the most efficient operating vehicle. A local company is useful when you have local staff, local premises, local customers, or regulated local activity. If your business earns income internationally, an international structure may be cleaner.

• ›US LLC — often suitable for non-US owners with non-US income who need simple administration and good payment access.
• ›Singapore company — useful where banking reputation, Asian counterparties, and strong legal infrastructure matter.
• ›UAE company — useful for zero-tax or low-tax operating structures when substance, management, and banking can be handled properly.

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 — introduced in 2025, this visa allows non-EU remote workers to reside in Bulgaria while working for foreign employers, providing a structured route into one of the lowest-tax jurisdictions in the EU.
• ›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 remains one of the lower-cost EU options, especially outside Sofia. The useful comparison is not with rural Bulgaria, but with the standard expected by a foreign entrepreneur or retiree who wants good housing, private healthcare and international travel access.

Typical monthly costs for an internationally mobile professional or family in Bulgaria (2026 planning ranges):

Comfortable single professional (no children): BGN 3,240–5,760/month (£1,400–2,500 / $1,800–3,200)

Family of four with private schooling: BGN 8,100–14,400/month (£3,500–6,250 / $4,500–8,000)

These figures are planning ranges, not promises. The actual budget in Bulgaria depends heavily on housing quality, neighbourhood, school choice, healthcare needs, car ownership, travel frequency, and whether you are trying to live like a local or maintain a Western expatriate standard.

Buying real estate in Bulgaria can be useful for lifestyle, residence planning, and long-term anchoring, but it should not be treated as a simple shortcut to tax residence. Property is a factual tie; it can support a relocation story when used properly, but it can also create tax, inheritance, financing, and exit issues if bought before the wider plan is clear.

For internationally mobile buyers, the main points in Bulgaria are:

• ›Ownership rules: Foreigners can buy buildings and apartments directly, while land ownership by non-EU nationals may require a Bulgarian company or other structure.
• ›Transaction costs: Acquisition costs include transfer tax, notary fees, registration fees, and agency commission, usually still modest compared with Western Europe.
• ›Market and rental profile: Sofia, Plovdiv, Varna, Burgas, and ski resorts such as Bansko have very different rental and resale profiles.
• ›Residence and tax angle: The main due-diligence issues are land status, building permits, condominium management, old construction quality, and whether the property is suitable for actual year-round living.

The practical approach is to decide first whether the property is primarily for living, residence support, rental yield, asset protection, or lifestyle. Those are different purchases. A good real estate decision in Bulgaria begins with title due diligence, tax-residence planning, inheritance review, and a realistic exit strategy — not with glossy developer brochures.

Transaction cost table (Bulgaria)

Retiring in Bulgaria can make sense for the right profile, but it should not be reduced to a simple tax headline. The real question is whether the country gives you the right combination of residence security, pension treatment, healthcare access, cost of living, climate, and day-to-day comfort. A retirement move is harder to reverse than a business relocation, so practical quality of life matters as much as tax.

For retirees considering Bulgaria, the main points are:

• ›Residence route: The practical route is usually the EU citizens can register residence; non-EU retirees usually rely on long-stay residence based on pension income and accommodation. This should be confirmed before making property commitments or moving assets, because a pleasant destination is not useful if the residence basis is weak.
• ›Pension income: Foreign pension income may be taxable in bulgaria unless treaty rules allocate taxing rights elsewhere; bulgaria’s flat-tax system can still be attractive. The decisive point is often not only local tax, but whether the pension-paying country continues to tax the pension at source.
• ›Healthcare: Private healthcare in sofia, plovdiv, and varna is affordable, while public healthcare quality varies. Retirees should arrange private insurance or a clear local healthcare pathway before arrival, especially where pre-existing conditions are involved.
• ›Cost of living and lifestyle: Low cost of living, mountains, black sea coast, and a slower pace than western europe. The country can work well where the retiree’s lifestyle expectations match the local rhythm rather than an imagined expatriate brochure.
• ›Climate and practical fit: Four distinct seasons, with hot summers, cold winters, and milder conditions on the black sea coast. Climate, language, bureaucracy, transport, and access to family often decide whether the move remains attractive after the first year.

Bulgaria should therefore be assessed as a full retirement platform, not merely as a tax jurisdiction. The best candidates are retirees who have stable foreign income, good health coverage, a realistic view of local bureaucracy, and a clear plan for where they will live, how they will receive care, and how their pension will be taxed both locally and at source.

US citizens and long-term green card holders are taxed by the United States on their worldwide income, regardless of where they live. Relocating to Bulgaria does not end US tax obligations — it changes the picture, but does not eliminate it.

Key considerations for US citizens in Bulgaria:

• ›Foreign Earned Income Exclusion (FEIE): US citizens who qualify as bona fide residents of Bulgaria or pass the physical presence test can exclude a significant amount of foreign earned income from US federal income tax. This applies to wages and self-employment income — not passive income such as dividends, interest, capital gains, pensions, or rental income.
• ›Foreign Tax Credit: Income tax paid in Bulgaria can generally be credited against US tax on the same income, reducing or eliminating double taxation. The credit is particularly important for income not covered by the FEIE and for taxpayers whose income exceeds the annual FEIE threshold.
• ›Treaty position: Treaty relief between the United States and Bulgaria is limited or fact-dependent. Before relying on any treaty position, US citizens should confirm the current treaty status and the exact income category with a qualified US international tax adviser. A treaty does not automatically remove US filing obligations, and most treaties contain savings-clause rules that preserve US taxation of citizens.
• ›FBAR: US persons with bank accounts in Bulgaria exceeding $10,000 in aggregate must file FinCEN Form 114 (FBAR) annually. Failure to file can carry severe penalties, even when no tax is due.
• ›FATCA: US citizens may also need to report foreign financial assets on Form 8938. Banks in Bulgaria may separately identify US account holders under FATCA procedures and report account information through the relevant channels.
• ›Social Security and self-employment tax: The FEIE reduces income tax but does not automatically eliminate US self-employment tax. Whether US Social Security tax applies depends on employment status, entity structure, and any applicable totalization agreement.

US citizens considering Bulgaria should work with a qualified US international tax adviser alongside local counsel. The interaction between US tax law and Bulgaria tax law is manageable, but it requires careful planning before the move, not after the first filing deadline arrives.

Bulgaria participates in the OECD Common Reporting Standard (CRS), the global framework for automatic exchange of financial account information between tax authorities. Bulgaria has been exchanging information with partner jurisdictions since 2017.

In practical terms, this means: if you hold bank accounts or financial assets in Bulgaria, the financial institution in Bulgaria will report your account details — balance, income, and identifying information — to the local tax authority, which will then automatically share this information with the tax authority of your country of tax residence.

The key point is that CRS follows tax residence, not nationality or citizenship. For example, a Swedish citizen who has genuinely become tax resident in Bulgaria is treated, for CRS purposes, as a tax resident of Bulgaria — not as a Swedish reportable person merely because of the passport. The same principle applies to any non-US nationality: the account should be reported to the country of tax residence, not automatically to the country of citizenship.

CRS does not create a tax liability — it creates transparency. If you are properly tax resident in Bulgaria and have correctly severed residency in your home country, CRS reporting simply confirms what should already be declared. The risk arises when individuals attempt to maintain dual residency, leave old tax-residence indicators unresolved, or claim Bulgaria residency without genuinely living there.

US citizens are different. The United States does not participate in CRS in the same way. Americans are affected by FATCA instead: banks outside the United States generally identify US persons and report their account information through FATCA channels to the US authorities, regardless of whether the person is tax resident in Bulgaria or anywhere else.

Upon establishing residence in Bulgaria, you will need to obtain a Bulstat / personal identification number from the competent local authority. This is required for most financial and legal transactions in Bulgaria, including opening bank accounts, signing contracts, registering with tax authorities, and dealing with public offices.

You will also need to obtain or complete the relevant Bulgarian residence card or EU registration certificate process once your residence status has been approved. This document or registration record becomes your practical proof of residence in Bulgaria and is usually required for banking, telecom contracts, utilities, leases, property transactions, and day-to-day administrative matters.

• ›Driving licences from most countries are accepted only for a limited period after arrival. Once you become resident in Bulgaria, you should verify whether your licence can be exchanged directly or whether a local medical certificate, translation, theory test, or practical test is required.
• ›Health insurance should be arranged before arrival unless you are immediately covered by a local public system. In many cases, private international cover is the safest bridge solution while residence, employment, or social-security registration is still being completed.
• ›Importing personal effects should be planned before shipping anything to Bulgaria. Household goods may qualify for relief when imported shortly after taking up residence, but customs paperwork, inventory lists, timing rules, and vehicle-import duties can make late or informal shipping expensive.
• ›Proof of address and banking are often linked. Banks, telecom providers, and government offices may require a lease, utility bill, local address certificate, or residence registration before they will open an account or complete onboarding.
• ›Ongoing local compliance should not be treated as an afterthought. Calendar reminders for residence renewals, tax registrations, local filings, health-insurance renewals, and address updates help prevent administrative problems that can later undermine the tax-residency position.
