Quick Answer: Tax Residency in Bulgaria
You are generally considered a tax resident of Bulgaria if you spend more than 183 days in the country within a calendar year, or if your centre of vital interests (family, business, or economic ties) is located in Bulgaria. Bulgarian tax residents are subject to Personal Income Tax on their worldwide income, subject to relief under applicable Double Taxation Treaties (DTTs).
What is Tax Residency in Bulgaria?
Being a tax resident in Bulgaria means you’re liable to pay taxes on your worldwide income in the country. There are four main criteria that determine your tax residency:
- Physical Presence: This is the most common way to establish tax residency. If you spend more than 183 days in a calendar year within Bulgaria, you’ll be considered a resident for tax purposes in that year. It’s important to note that both the day you enter and depart Bulgaria count towards your total. Days spent solely for education or medical treatment typically don’t qualify.
- Permanent Address and Economic Ties: Even with a shorter stay, you might be considered a resident if you have a permanent address registered in Bulgaria. This, combined with factors like owning property or having family living in the country, can indicate your economic ties are centered in Bulgaria.
- Center of Vital Interests: This concept goes beyond just physical presence. It considers where your business interests lie, where you hold bank accounts, and the location of your main residence. If these factors show a closer connection to Bulgaria than any other country, you might be considered a resident for tax purposes.
- Assignment Abroad: If you’re a Bulgarian citizen or resident assigned to work abroad by a Bulgarian company or state entity, you and your family members may be considered tax residents in Bulgaria despite your physical location.
Being a tax resident in Bulgaria does not automatically provide proof of that status. In practice, foreign tax authorities, banks, and counterparties often require an official Certificate of Tax Residence issued by the Bulgarian National Revenue Agency.
For a practical explanation of when this certificate is required and how to obtain it, see our guide:

Double Taxation Treaties (DTTs)
Bulgaria has signed Double Taxation Treaties (DTTs) with many countries.
These treaties are designed to prevent the same income from being taxed twice, but they do not eliminate tax automatically. Instead, they coordinate taxing rights between countries and may include:
- tie-breaker rules for determining tax residency,
- reduced withholding tax rates,
- and relief mechanisms such as tax credits or exemptions.
Where applicable, a DTT may help resolve situations where a person could otherwise be considered tax resident in more than one country.
For a detailed explanation of how treaties work in practice, see our guide:
Double Tax Treaty Bulgaria: How It Works
For individuals relocating from high-tax jurisdictions such as the Netherlands, additional exit tax considerations may apply before Bulgarian tax residence becomes effective.
Benefits of Tax Residency in Bulgaria
Bulgaria applies a flat personal income tax rate of 10%, which is among the lowest in the EU. Bulgarian tax residents are generally taxed on their worldwide income, while non-residents are taxed only on Bulgarian-source income. In cross-border situations, relief from double taxation is typically available under applicable Double Taxation Treaties. For residents who generate property income in Bulgaria — including through platform-based rentals — see our guide to Airbnb and short-term rental rules in Bulgaria for the applicable tax and compliance framework.
Important Disclaimer on Tax Residency
Important note:
Tax residency is assessed based on all relevant facts and circumstances. Meeting or failing to meet a single criterion does not automatically determine residency, and outcomes may differ where double tax treaties apply. The Bulgarian National Revenue Agency (NRA) may assess tax residency differently depending on the specific situation.
