Where you pay tax depends on which country you are tax resident in, not on your citizenship. A Bulgarian tax resident is taxed in Bulgaria on worldwide income. If you are not resident, Bulgaria taxes only your Bulgarian-source income — rent or the sale of a property here, for example. When two countries claim the same income, the double taxation treaty between them decides.

When you are a Bulgarian tax resident

Under Art. 4 of the Personal Income Tax Act, a resident, regardless of citizenship, is a person who:

  • has a permanent address in Bulgaria;
  • stays in Bulgaria for more than 183 days in any 12-month period;
  • has been posted abroad by the Bulgarian state or a Bulgarian company (and their family members);
  • has their centre of vital interests in Bulgaria — family, property, place of work or business, the place from which they manage their property.

Art. 4(5) adds an important exception: a person with a permanent address in Bulgaria is not resident if their centre of vital interests is not in Bulgaria. When counting the 183 days, the day of arrival and the day of departure each count, and time spent in Bulgaria only for study or medical treatment does not.

If you are a Bulgarian tax resident

You declare all your income in Bulgaria, including income from abroad, in an annual tax return by 30 April of the following year. Tax on the total annual tax base is 10% (Art. 48). Tax paid abroad is taken into account as the treaty provides: either as a tax credit or through “exemption with progression”. You attach proof of the foreign tax to the return; with exemption with progression this is optional (Art. 50(5) and (6)).

If you are not resident: income from Bulgaria

A non-resident pays tax in Bulgaria only on Bulgarian-source income. Most such income — rent, interest, the sale of property, royalties — is subject to a 10% final tax (Art. 37 and Art. 46). No annual return is usually filed for it.

10% rate under Art. 46 and Art. 48 of the Personal Income Tax Act. When the tenant is a company, it withholds and pays the tax for you.

Rent from a property in Bulgaria

If the tenant is a company or a self-employed person, they withhold 10% and pay it to the National Revenue Agency. If the tenant is a private individual, you pay the tax yourself by the end of the month following the quarter in which you received the rent and file a return under Art. 55(1) (Art. 65(1) and Art. 67(1)).

If you are resident in an EU or EEA country, you may choose to have the tax recalculated as it would be for a resident, by filing an annual return under Art. 50 (Art. 37a). All your income subject to final tax for that year is then included, and any overpaid tax is refunded up to the amount you cannot credit in your country of residence.

Double taxation treaties

Bulgaria has 70 treaties in force covering 71 countries (the treaty with the former Yugoslavia applies to Serbia and Montenegro). The full list with signature and entry-into-force dates is on the NRA website, and the treaty policy is on the Ministry of Finance website. Whether the credit or the exemption method applies is set out in each treaty.

Treaty relief is not automatic. A non-resident proves entitlement under Art. 135–142 of the Tax and Social Insurance Procedure Code: that they are resident in the other country, that they are the beneficial owner of the income, and that they have no permanent establishment in Bulgaria to which the income is connected.

If you live abroad and have income from Bulgaria

  1. Get a certificate of residence

    It is issued by the tax authority of the country where you live, for the relevant year.

  2. Prepare a declaration

    Stating that you are the beneficial owner of the income and that it is not connected with a permanent establishment in Bulgaria. Attach the contract and documents showing the amount of income.

  3. Up to €255,645.94 a year from one payer

    You give the documents only to the payer, who applies the relief and reports the payments to the NRA by 31 March of the following year (simplified procedure).

  4. Above that threshold

    A request is filed with the NRA — at the directorate where the payer is registered, or in Sofia. If an audit is opened, the NRA decides within 60 days.

  5. If tax has already been withheld

    File a refund request with the same evidence. The NRA issues its decision within 30 days of receiving it, unless it opens an audit.

Certificate of Bulgarian tax residence

If you are a Bulgarian resident and a foreign tax authority asks for proof, the NRA issues a certificate of residence — under Bulgarian law or under a specific treaty, for the current or a past year. The request (form Окд-273) can be filed online with a qualified electronic signature or a PIN code, by post, by email or at an NRA office. A separate request is needed for each country and for each period longer than one year. If the foreign authority has its own form, attach it with a translation by a sworn translator.

Documents you need

  • For a certificate of Bulgarian residence — request on form Окд-273, stating the country and year
  • The foreign tax authority’s form, if required, with a Bulgarian translation
  • For treaty relief in Bulgaria — certificate of residence from the country where you live
  • Declaration that you are the beneficial owner and have no permanent establishment in Bulgaria
  • Contract and documents showing the amount and type of income (for example a lease)
  • If acting through a representative — a power of attorney

Frequently asked questions

I have a permanent address in Bulgaria but live and work abroad. Am I resident?

Not necessarily. Under Art. 4(5), a person with a permanent address in Bulgaria is not resident if their centre of vital interests is outside the country. Your position depends on the facts — family, home, work. If in doubt, ask the National Revenue Agency.

I rent out my flat in Bulgaria. Do I need to file an annual return?

If you are not resident — usually not. You pay a 10% final tax on the rent by the end of the month after the quarter and file an Art. 55 return. EU/EEA residents may choose recalculation through an annual return.

Where can I find the treaty with my country?

In the NRA list (section “International activities” → “Double taxation treaties”), with countries in alphabetical order, signature and entry-into-force dates, and the texts.

How much does the certificate of residence cost?

The NRA page does not state a fee. It takes 7 days if you file at the competent directorate and 14 days if you file elsewhere.

Do I pay tax in both countries?

The treaty decides which country taxes the income and how the other avoids double taxation — by a tax credit or an exemption. That is why proving your residence with a certificate matters.
