Bulgaria 2026: 10% flat tax, Sofia from €1,100/month, one of the EU's most aggressive FIRE plays

A 10% flat tax on personal income (ZDDFL Art. 48, in force since January 1, 2008 and untouched ever since): the lowest headline rate in the European Union. It applies to wages, rents, capital gains, and interest. Dividends carry an even softer 5% final withholding (ZDDFL Art. 38). Sources: OECD Tax Database 2025, NRA Bulgaria.

According to the NSI Bulgaria (Q4 2025 CPI), a FIRE couple lives on €1,400 to €2,000 a month including rent in Sofia, in residential districts like Lozenets, Iztok, or Boyana. In Plovdiv and Varna, the envelope drops to between €1,100 and €1,700. It is one of the lowest costs of living in Central Europe inside an EU framework, even though Sofia rents climbed 18% between 2023 and 2025 on the back of Schengen accession.

Dividends from Bulgarian or other EU sources are taxed in Bulgaria at a 5% final withholding. Dividends from non-EU sources are taxed at the same 5% for a Bulgarian resident, with a foreign tax credit subject to a bilateral treaty. Where your home country has a double-taxation treaty with Bulgaria, the withholding on dividends at source is usually capped (commonly 5% to 15%) and credited against your Bulgarian tax.

European Union nationals only need to file a residence declaration (Adresna Registratsia) after 90 days to receive an EU residence certificate within 30 days. Non-EU nationals have several routes: the D investor visa (setting up a business, or a property purchase above BGN 600,000), the retiree visa (on proof of a stable pension above the Bulgarian minimum wage), or the self-employed visa for those carrying on an activity locally.

Yes. Bulgaria joined Schengen for air and sea borders on March 31, 2024, then for land borders on January 1, 2025 (Council of the European Union Decision 2024/210). Border controls with Romania, Greece, and the rest of the EU have been lifted, smoothing mobility for Bulgarian residents into the other Schengen states without a visa or systematic checks.

Bulgaria has used the euro since January 1, 2026. The Bulgarian lev (BGN) was replaced at the fixed rate of €1 = BGN 1.95583, after years of being pegged to the German mark and then to the euro through a currency board. For a FIRE resident in Sofia, Plovdiv or Varna, rents, salaries and bills are now denominated directly in euros.

An international private health insurance plan covers most FIRE expats for a budget of €70 to €180 a month per adult, depending on age and the breadth of coverage. The leading insurers are Bulstrad VIG, DZI Insurance, and Allianz Bulgaria. The Bulgarian private network (Tokuda Hospital, Acibadem City Clinic, Hill Clinic) delivers Western European standards at moderate cost. The public NZOK system remains underfunded (4.8% of GDP per Eurostat 2024).

Plovdiv (the country's second city and cultural capital) offers a couple's budget of €1,100 to €1,500 a month including rent, with a dense cultural scene and a regional airport. Varna, on the Black Sea, runs the same budget with coastal access but with sharp summer tourist seasonality. Bansko (skiing and digital nomadism) is the most aggressive Lean FIRE option, at €700 to €1,000 a month off-season, carried by an international community that stays active all year.

A freelancer can opt for Svobodna Profesiya status (liberal profession) or set up an EOOD (the single-shareholder limited company). As a liberal professional, net income is taxed at 10% after a 25% flat-rate cost deduction, for an effective rate of roughly 7.5%. As an EOOD, corporate tax sits at 10%, followed by a 5% final withholding on dividend distribution, for an all-in burden of about 14.5%. The VAT threshold sits at BGN 100,000 (around €51,000) of annual turnover.

Yes. Bulgarian tax residency kicks in from 183 days of presence in the year, or as soon as Bulgaria becomes the center of your vital interests. A Bulgarian resident reports worldwide income to the NRA on Form 50 by April 30. A double-taxation treaty between your home country and Bulgaria prevents double taxation: foreign-source income (rents on property abroad, dividends from foreign companies) is generally taxed at source and gives rise to a foreign tax credit in Bulgaria.

The Anglo-American School of Sofia (American program plus IB) charges €18,000 to €22,000 a year. The American College of Sofia (high school only) sits at around €11,000 a year. The Lycée Victor-Hugo de Sofia (AEFE-accredited, French curriculum) is the most affordable international option at €6,500 to €9,000 a year per child depending on the grade. All three are concentrated in Sofia.

Transfer costs on a Sofia real estate purchase amount to around 2 to 3% of the acquisition price: 0.1% land registry tax (Imotni Registar), 2.5% municipal transfer tax, and 0.5 to 1% notary fees (Notarialni Tarifi). On top of that, VAT (DDS 20%) applies on new builds bought from a developer, but not on existing property.
