Bulgaria – Taxation

How does the tax system in Bulgaria work?

Bulgaria’s tax system is administered centrally by the National Revenue Agency (NRA), which operates under the oversight of the Ministry of Finance. In contrast to federal models such as those found in Germany or Switzerland, Bulgaria levies no regional or state-level income tax — all personal income tax is collected at the national level under the Personal Income Tax Act (PITA). The system is widely regarded as one of the most transparent and competitive within the EU, applying a uniform 10% rate to both personal and corporate income.

Tax residency in Bulgaria is determined either by the amount of time an individual spends in the country or by the existence of strong personal or economic connections to it. The primary rule is that spending 183 days or more in Bulgaria during any 12-month period qualifies a person as tax resident. Residency is established for the calendar year in which the cumulative stay surpasses that threshold, with both the day of arrival and the day of departure each counted individually as days of presence.

An alternative route to tax residency exists for individuals who maintain a permanent address in Bulgaria and whose centre of vital interests is demonstrably located there, even if they fall short of the 183-day requirement. In assessing where the centre of vital interests lies, the tax authority examines factors such as the location of employment or business activity, social security payments, residence permits, and real estate ownership.

Importantly, holding a permanent address in Bulgaria does not automatically confer tax residency — nor does it necessarily prevent it. Where a registered address exists but the centre of vital interests is located elsewhere, the individual will not be treated as a Bulgarian tax resident. This distinction matters considerably for those who maintain a Bulgarian address while living primarily abroad.

Bulgarian tax residents are subject to tax on their worldwide income — every source of earnings, whether domestic or foreign, falls within the scope of Bulgarian personal income tax. Non-residents, by contrast, are taxed solely on income derived from Bulgarian sources. This residency-based approach is common across most European jurisdictions and differs fundamentally from the citizenship-based model applied only in a small number of countries, notably the United States.

The tax period runs from 1 January to 31 December each year. An exception applies to income subject to a final withholding tax, which is handled outside the standard annual cycle. For the most current rules and any recent legislative changes, always refer directly to the NRA website.

Does Bulgaria have double taxation agreements, and how do they affect expats?

Bulgaria has concluded more than 70 bilateral double taxation treaties, providing a broad framework for preventing the same income from being taxed in two jurisdictions simultaneously. These agreements typically lower withholding tax rates on cross-border income flows and establish mechanisms for eliminating double taxation when residents derive income from abroad. A full and up-to-date list of treaty partners is available through both the NRA website and the Ministry of Finance portal.

It is important to understand that treaty protection is not automatic — these agreements coordinate taxing rights between the two signatory countries and set out the conditions under which relief is available. They also include provisions for resolving situations where an individual could otherwise be treated as tax resident in more than one country at the same time.

In practical terms, a double taxation treaty allows tax paid in one country to be offset against liability arising in the other, ensuring the same income is not subject to full taxation twice. Many treaties also grant exemptions or reduced rates on specific categories of cross-border income, including interest, royalties, dividends, capital gains, and other payments flowing between residents of the treaty countries.

Where income originates in a country that has concluded a treaty with Bulgaria, double taxation is resolved according to the terms of that specific agreement. In cases where no treaty exists, Bulgaria may still provide unilateral relief in the form of a foreign tax credit for taxes already paid abroad. Both routes — treaty-based and unilateral — are available depending on the circumstances.

To formally invoke treaty protection, individuals are generally required to present a Tax Residence Certificate (TRC). Issued by the National Revenue Agency, this official document confirms an individual’s or entity’s tax residency status in Bulgaria under the terms of a particular treaty. Processing typically takes around one month. The certificate serves as authoritative evidence of Bulgarian tax residence and is presented to foreign tax authorities when claiming treaty benefits or establishing that a person is no longer resident in their previous country for tax purposes.

Where a double taxation treaty is applicable, its provisions take precedence over domestic Bulgarian law in determining residency status — an important point for those with ties to multiple countries. If you could be considered tax resident in two countries simultaneously, the relevant treaty may contain tie-breaker rules designed to establish a single country of residence for tax purposes. Cross-border situations of this kind warrant specialist advice; the current treaty list should always be verified via the NRA’s official website.

What taxes do expats need to pay in Bulgaria?

Bulgaria’s overall tax framework is considerably more streamlined than that of many other EU countries. Below is an overview of the principal taxes that an expat resident in Bulgaria is likely to encounter.

Personal Income Tax

A uniform rate of 10% applies to all categories of personal income, covering wages, salaries, and self-employment earnings alike. Every lev (BGN) of taxable income is subject to this single rate, with no tiered bands or higher thresholds. There is no general tax-free personal allowance, though limited exemptions exist for specific income types and for individuals with disabilities. As of 2026, Bulgaria adopted the euro as its official currency; all tax figures previously denominated in BGN convert at the fixed rate of 1 EUR = 1.95583 BGN, and tax and social security returns for periods ending on or after 1 January 2026 must be submitted in EUR.

Sole traders face a higher rate of 15%. While income from most sources is taxable, a number of exceptions apply — among them, proceeds from the sale of one or two residential properties under qualifying conditions, scholarships for study within Bulgaria or abroad, and interest earned on deposits held with domestic commercial banks and branches of foreign banks.

Capital Gains Tax

Capital gains are taxed at the standard flat rate of 10% and are generally treated as ordinary taxable income. Certain exemptions are available, particularly for real estate that has been owned for the required minimum period and for assets received as gifts. A primary residence qualifies for full exemption from capital gains tax if the property has been held for more than three years.

Gains arising from transactions in virtual currencies are explicitly included within the taxable category of financial asset disposals. The tax base for all such transactions may be reduced by a fixed 10% allowance to account for costs associated with investment activity — a recent legislative development of particular relevance to those holding cryptocurrency assets.

Dividend Tax

Dividends and liquidation quotas distributed to both residents and non-residents are subject to a final withholding tax of 5%. Dividends paid by a Bulgarian company to legal entities resident in EU or EEA member states may qualify for exemption, and distributions between two Bulgarian resident companies are generally also exempt.

Wealth Tax

Bulgaria levies no annual tax on personal net wealth, which facilitates the long-term accumulation and holding of assets. This distinguishes Bulgaria from jurisdictions such as Norway and Switzerland, which impose recurring charges on an individual’s total net worth.

Property Tax

Real estate is subject to an annual property tax ranging from 0.01% to 0.45% of the property’s assessed value, with the precise rate determined by each municipality. Following Bulgaria’s transition to the euro on 1 January 2026, municipalities now assess and issue property tax and waste collection fee notices in EUR. Property owners should also account for an annual municipal waste collection fee, the amount of which is set locally and varies from one municipality to another.

Inheritance and Gift Tax

Inheritance tax applies to property situated in Bulgaria or abroad when inherited by Bulgarian citizens, and to property located in Bulgaria when inherited by non-residents. The rate is 0.4%–0.8% for inheritances passing between relatives in the lateral line, rising to 3.3%–6.6% where the heir is unrelated to the deceased. Gifts and inheritances transferred to a spouse or relatives in the direct line are fully exempt. This relatively light inheritance tax regime compares favourably with countries such as Spain, France, and Germany, where much higher rates can apply, making Bulgaria an appealing jurisdiction for those concerned with intergenerational wealth transfer.

Social Security Contributions

Social security and health insurance contributions in Bulgaria are entirely separate from personal income tax and must be calculated and paid in addition to the 10% flat rate. The burden is shared between employers and employees, while self-employed individuals are responsible for the full combined amount themselves.

The aggregate social security rate is approximately 32.7%, with employees contributing around 13.78% and employers around 18.92% — though these percentages may vary marginally by sector. Coverage encompasses pension, health, unemployment, workplace accident, and maternity insurance. For 2026, the monthly earnings cap above which contributions are not charged is approximately EUR 1,969 (converted from BGN 3,850 at the fixed rate). This figure is reviewed annually; always confirm the current cap with the NRA. Unlike some Western European systems, the cap applies only to certain contribution categories rather than eliminating all contributions once a ceiling is reached.

Are there any tax breaks or special regimes for expats in Bulgaria?

Bulgaria does not currently offer a dedicated non-domicile or remittance-based tax regime specifically designed to attract new arrivals, of the kind seen in Portugal’s NHR programme or Italy’s flat-tax scheme for incoming residents. Nevertheless, several structural features of the Bulgarian tax system deliver genuine advantages for internationally mobile individuals and high-net-worth residents.

The core attractions are the flat 10% personal income tax rate and the 5% dividend tax, which together produce a low blended effective rate on investment income. The complete absence of a wealth tax reinforces this advantage, resulting in an overall tax burden that is typically far lighter than that faced by residents of higher-tax EU states.

From 2025, a child tax relief measure allows a deduction of BGN 6,000 (approximately EUR 3,068) per dependent child from the annual tax base, subject to the relevant statutory conditions. Where the child has a disability, the deduction rises to EUR 6,135.50 (BGN 12,000) for 2025. These reliefs are accessible to Bulgarian tax residents, including expats who satisfy the residency criteria.

Additional deductions are available for contributions to voluntary pension funds, voluntary health insurance schemes, and life insurance policies, each deductible at up to 10% of income within the applicable legal limits. For those engaged in long-term financial planning, these deductions can meaningfully reduce the taxable base each year.

Individuals with a recognised disability of 50% or more may deduct up to BGN 7,920 (approximately EUR 4,050) from taxable income for the 2026 tax year.

For location-independent professionals, a Digital Nomad visa introduced in mid-2025 provides a clear legal route for non-EU remote workers to take up residence in Bulgaria and potentially establish tax residency under the standard statutory tests. This relatively recent development mirrors comparable programmes elsewhere in the EU. It is worth noting, however, that becoming a Bulgarian tax resident brings worldwide income within the Bulgarian tax net — albeit at the highly competitive flat rate.

Bulgaria’s EU membership means that gains from the disposal of certain securities may in specific circumstances attract preferential treatment under applicable EU directives. Given the evolving nature of rules in this area, consulting a tax professional well versed in cross-border investment structures is strongly recommended before making significant financial decisions.

How and when do expats file a tax return in Bulgaria?

Bulgarian tax residents are required to submit an annual personal income tax return by 30 April of the year following the relevant tax year, which runs from 1 January to 31 December. A return must be filed by anyone who has received income not fully covered by employer withholding at source, or who has income from foreign sources. For the most current deadlines and filing requirements, refer to the NRA official website.

The step-by-step process for filing as a foreign resident is as follows:

1. Obtain a Bulgarian personal identification number (ЕГН or ЛНЧ). EU citizens who register their residence are assigned an ЕГН (civil identification number), while non-EU nationals receive a ЛНЧ (personal number of a foreigner). This number is a prerequisite for any interaction with the Bulgarian tax authority.
2. Register with the National Revenue Agency (NRA). After arriving in Bulgaria, register with the NRA and obtain a Bulgarian tax identification number. This can be done in person at any local NRA territorial office.
3. Gather your income documentation. Compile records of every source of income received during the tax year — including employment, self-employment, rental income, investment returns, and earnings from abroad — together with any withholding tax certificates that may be relevant.
4. Determine your tax base. Taxable annual income encompasses all cash and non-cash receipts, after subtracting any exempt amounts. Each category of income — employment, business activity, property disposals, and so on — follows a specific regime for calculating the applicable tax base. The overall taxable income is the aggregate of the individual bases across all income sources.
5. Complete and submit your tax return. Returns must be filed individually; there is no provision for joint filing by spouses or households. Submissions can be made electronically via the NRA online portal using a personal identification code or a qualified electronic signature, or alternatively on paper at a local NRA office.
6. Pay any tax due. Any advance payments made during the year are credited against the final annual liability, with the balance due by 30 April. For those in employment, income tax is typically deducted at source by the employer throughout the year, with any outstanding amount or refund reconciled through the annual return.
7. Apply for a Tax Residence Certificate if needed. Anyone wishing to claim benefits under a double taxation agreement must obtain a Tax Residence Certificate from the NRA. This document confirms official tax residency status and is required when asserting treaty entitlements to a foreign tax authority.

Penalties for late filing

An individual who omits or incorrectly reports data in their tax return, resulting in an understated tax liability or an unwarranted exemption, may be subject to a penalty of up to BGN 1,000. Failure to submit a return by the statutory deadline may attract a penalty of up to BGN 500, with both amounts doubling in the event of a repeat offence. It is always preferable to file by the deadline even where some details remain uncertain — an amended return can be submitted subsequently, but missing the filing date entirely is likely to result in a greater penalty exposure.

What are the tax implications of leaving Bulgaria?

Bulgaria does not currently apply a formal exit tax on unrealised capital gains at the point when a taxpayer permanently departs, unlike certain other EU member states such as the Netherlands or Germany, which levy charges on accrued gains that have not yet been crystallised through a sale. That said, ceasing to be a Bulgarian tax resident carries several meaningful consequences that call for advance planning.

From the moment Bulgarian tax residency ends, the obligation to pay Bulgarian tax on worldwide income also ceases. However, all Bulgarian tax liabilities that accrued up to the date of departure remain enforceable. In practice, this means filing a final annual personal income tax return covering the period from 1 January through to the date on which residency was relinquished, submitted by the standard 30 April deadline of the following year.

Income that continues to flow from Bulgarian sources after departure — such as rent from a Bulgarian property, dividends distributed by Bulgarian companies, or proceeds from the disposal of Bulgarian assets — remains taxable in Bulgaria as non-resident income. The applicable rate for non-residents on Bulgarian-source income is the same flat 10%.

To formally end Bulgarian tax residency, the NRA should be notified of the change in personal circumstances. No single statutory exit procedure exists for individuals equivalent to a corporate deregistration, but failing to inform the NRA of a departure risks an assumption that filing obligations continue. Maintaining thorough records of the departure date — including transport documents, utility disconnections, and any address deregistration — will help substantiate the claim that the 183-day threshold and centre of vital interests tests are no longer met.

In the year of departure, it is possible to be treated as tax resident in two countries simultaneously during a transitional period. Where a double taxation treaty applies, tie-breaker provisions may determine a single country of residence for tax purposes. Split-year treatment considerations can be particularly complex; seeking advice from a cross-border tax specialist well ahead of a planned move is strongly advisable.

Practical tips for managing taxes as an expat in Bulgaria

• Keep a precise record of your time in Bulgaria. Tax residency is established in the year your presence exceeds 183 days, with arrival and departure days each counted separately. Maintain a detailed log of travel dates, supported by transport receipts and accommodation records, so that your residency position can be demonstrated clearly if ever questioned.
• Plan ahead for when worldwide income becomes taxable. Once you cross the 183-day threshold or establish your centre of vital interests in Bulgaria, all global income becomes subject to Bulgarian taxation. If you anticipate significant foreign income events — such as large asset sales or substantial dividend distributions — in a year when your residency status may be transitioning, plan those events carefully in advance.
• Activate double taxation treaty protection promptly. Apply for a Tax Residence Certificate from the NRA as soon as you qualify as a Bulgarian tax resident, since this document is required when claiming benefits under any applicable treaty. Presenting it to the tax authority in your previous country of residence helps establish formally that you are no longer resident there for tax purposes.
• Take professional advice before disposing of significant assets. Capital gains are taxed at a flat 10%, with exemptions available for real estate held for the required period. The timing of a disposal relative to your residency status can have a considerable effect on the resulting liability. Always seek specialist guidance before major transactions.
• Maintain comprehensive records of foreign income. As a Bulgarian tax resident, you must declare worldwide income in your return. Keep clear documentation of all overseas earnings, taxes paid to foreign authorities, and any foreign tax certificates — these are essential when applying for credits or relief against your Bulgarian liability.
• Adapt your record-keeping for the euro transition. Tax and social security returns for periods ending on or after 1 January 2026 must be submitted in EUR. Ensure that your accounting records are structured in a way that allows accurate euro-denominated reporting from that date.
• Engage a specialist tax adviser with cross-border expertise. Establishing tax residency can be a nuanced exercise, particularly for individuals with connections to more than one country. If your situation is not straightforward, consult a Bulgarian tax professional — ideally one familiar with the laws of both Bulgaria and your country of origin — to avoid costly errors.
• Monitor official sources for legislative changes. Tax legislation is subject to periodic revision, and staying abreast of updates is essential for compliance. Check the National Revenue Agency website regularly for the latest guidance, published at nra.bg.

Frequently asked questions: taxation in Bulgaria for expats

When do I become a tax resident in Bulgaria?

Tax residency in Bulgaria is determined either by how long you spend in the country or by the strength of your personal and economic ties to it. The principal rule is that staying 183 days or more in Bulgaria within any 12-month period makes you a tax resident. Residency may also arise if your centre of vital interests — where your key personal and financial connections are concentrated — is in Bulgaria, even if you have not reached the 183-day mark. You become a tax resident for the calendar year in which the 183-day cumulative period is completed.

Is my foreign income taxable in Bulgaria?

Once you are a Bulgarian tax resident, all income you earn globally — whether from Bulgarian or foreign sources — is subject to Bulgarian personal income tax. Relief for taxes already paid overseas is available through foreign tax credits, and Bulgaria’s network of more than 70 double taxation treaties further reduces the risk of the same income being taxed in full by two different countries. Non-residents are taxed solely on income that arises from Bulgarian sources.

What is the income tax rate in Bulgaria?

Bulgaria applies a flat 10% income tax rate to all taxable personal income in 2026, encompassing employment earnings, self-employment income, rental receipts, and capital gains. Dividends are taxed separately at a final withholding rate of 5%, and sole traders are subject to a 15% rate. There are no progressive bands or higher-rate thresholds.

How are pensions taxed in Bulgaria?

Foreign pensions received by Bulgarian tax residents are generally treated as part of worldwide income and taxed at the standard 10% flat rate. The precise treatment will depend on any double taxation treaty in force between Bulgaria and the country paying the pension, since some treaties assign exclusive taxing rights over pension income to the source country. Outcomes differ considerably depending on which treaty applies, so consulting a qualified tax adviser and checking with the NRA for treaty-specific guidance is recommended.

When is the deadline for filing a personal tax return in Bulgaria?

Personal income tax returns must be submitted by 30 April of the year following the relevant tax year. Each individual taxpayer files their own return — combined or joint returns are not permitted. Filing can be done electronically through the NRA online portal or in paper form at a local NRA office. Failing to meet the deadline may result in a penalty of up to BGN 500 (approximately EUR 256).

Does Bulgaria have a wealth tax or inheritance tax?

Bulgaria does not impose any annual tax on personal net wealth. Inheritance tax is levied, however: the rate is 0.4%–0.8% where the inheritance passes between relatives in the lateral line, and 3.3%–6.6% where the recipient has no familial relationship to the deceased. Assets transferred to a spouse or direct-line relatives through inheritance or gift are entirely exempt from tax.

How do double taxation treaties work in Bulgaria?

Bulgaria’s treaty network, covering more than 70 countries, is designed to prevent the same income from attracting full tax liability in two different jurisdictions. These agreements reduce withholding tax rates on cross-border payments and establish mechanisms for eliminating double taxation. To access treaty benefits, you must obtain a Tax Residence Certificate from the NRA confirming your status under the specific treaty between Bulgaria and the relevant country. The full treaty list is available through the NRA website.

What are the social security contribution rates for employees in Bulgaria?

Social security contributions in Bulgaria are shared between employees and employers, with the combined rate totalling approximately 32.7%. Employees contribute around 13.78% and employers around 18.92% of gross salary. The contributions fund pension, health, unemployment, occupational accident, and maternity insurance. For 2026, the monthly earnings ceiling above which contributions are not levied is approximately EUR 1,969. Self-employed individuals bear the entire combined rate themselves. Current thresholds should be verified with the NRA, as they are revised annually.
