Quick answer
In 2026 you are a Bulgarian tax resident if you meet any one of four tests: a permanent address in Bulgaria (unless your life is abroad), more than 183 days in any 12-month period, your centre of vital interests in Bulgaria, or a posting abroad by the Bulgarian state. Residents pay 10% on worldwide income; non-residents only on Bulgarian income.

Is this guide for you?
Read on if you…
- live in two or more countries and need to know if Bulgaria can claim you as resident;
- hold Bulgarian income, such as rent or dividends from an EOOD, while living elsewhere;
- want the legal rules before deciding to move in or out.
Probably not your case if you…
- want the step-by-step arrival checklist; see the practical guide to obtaining Bulgarian tax residency;
- are leaving and need the exit procedure; see ceasing your Bulgarian tax residency.
What are the four residence tests?
Meeting any one test makes you resident for the year. Here is how each works.
| Test | Detail | Strength as evidence |
|---|---|---|
| Permanent address in Bulgaria | Your registered permanent address (for citizens, the address in the civil register) | Strong, but overridden if your centre of vital interests is abroad (Art. 4(5) PITA) |
| More than 183 days | Physical presence in Bulgaria for more than 183 days in any 12-month period | Objective; the NRA can use border and phone data |
| Centre of vital interests | Your centre of vital interests – basically where your life is: home, partner, kids, main business – is in Bulgaria | Judged on family, property, work, business and social ties (Art. 4(6) PITA) |
| State posting | You are sent abroad by the Bulgarian state, its bodies or municipalities, together with family members | Narrow; mostly diplomats and public servants |
The permanent address test, explained
Bulgarian citizens always have a permanent address. That is why the law adds a safety valve. If your centre of vital interests is not in Bulgaria, the address alone does not make you resident.
Foreigners registering a permanent address must show real ties too. An address with no lease, no family and no work is weak.
The 183-day test, explained
Here's the catch. The 12-month window is not the calendar year. Arrive in September 2026, stay until March 2027, and you pass 183 days inside one 12-month window. You are then resident for the tax year in which you crossed the line.
The centre of vital interests test, explained
The NRA looks at the whole picture: where your family lives, where your home is, where you work or run your business, where you hold assets, and your social life. No single factor decides. A Bulgarian company you manage day to day, a long lease and children at a Bulgarian school point clearly to Bulgaria.
Resident or non-resident: what changes for your taxes?
| Income | Resident in 2026 | Non-resident in 2026 |
|---|---|---|
| Salary | 10% after social security | 10% on Bulgarian-source pay |
| Freelance fees | 10% after 25% allowance and contributions, via annual return | 10% withholding on Bulgarian fees, with the same allowance |
| Dividends | 5% final tax | 5% withholding; EU/EEA residents may reclaim the difference |
| Interest and royalties | 10% (bank deposit interest is exempt for residents) | 10% withholding, reduced by treaty |
| Capital gains | 10%, with exemptions | 10% on Bulgarian assets, with treaty relief |
| Foreign income | Taxable, foreign tax credited | Not taxable |
Good news for residents: Bulgaria's flat 10% makes the gap between resident and non-resident small. The real difference is scope. As a resident, your foreign salary, foreign rent and foreign dividends all come in. Read more in our guide to the personal income tax system in Bulgaria.
What happens if two countries say you are resident?
It happens often in a move year. Bulgaria has around 70 double tax treaties, mostly on the OECD Model.
The tie-breaker in Article 4 of each treaty runs in order:
- Permanent home – where you have a home available to you all the time.
- Centre of vital interests – if you have a home in both, where your personal and economic ties are closer.
- Habitual abode – where you spend more time.
- Nationality – your passport.
- Mutual agreement – the two tax authorities decide.
Ask the NRA for a certificate of tax residence to claim treaty benefits abroad. Foreign payers will want it before reducing withholding.
Rules differ in the region. Compare Romania's residence tests and Estonia's residence tests.
Your residence timeline: before, during and after a move
Before you arrive: decide which test you will rely on. For most nomads it is the 183-day test plus a lease. Plan your income structure first.
During the first year: log your days, register your address and start contributions. The NRA expects you to register as self-insured if you freelance.
After the first year: file your annual return by 30 April, request a residence certificate and keep your evidence for at least 5 years. The NRA can audit open years; the general limitation period is 5 years from the end of the year in which the tax was due.
Example – Marco, Italian product manager working remotely
Marco rents in Bansko from 1 October 2025 to 15 May 2026, then spends the summer in Italy, where he still owns a flat he uses. He passes 183 days in Bulgaria in the window ending April 2026. Both countries claim him for 2026. Under the Italy–Bulgaria treaty, he has a permanent home in both, so the centre of vital interests decides. His employer, partner and flat are in Italy. Result: Italy wins, and Bulgaria taxes only Bulgarian-source income.
Marco's case turned on one treaty article. Yours might too.

Check my tax setup →Common mistakes (and what they cost)
- Treating 183 days as a calendar-year count → you become resident earlier than you think and owe tax on worldwide income for that year.
- Keeping a permanent address while living abroad without proof of foreign ties → the NRA may treat you as resident and assess Bulgarian tax plus interest.
- Claiming treaty relief without a residence certificate → foreign payers withhold at full domestic rates.
- Ignoring social security → residence for tax and liability for contributions are separate tests; EU coordination rules decide where you pay contributions.
- Not filing when foreign income arrives → late filing penalties and interest at the statutory rate on unpaid tax.
Frequently asked questions
How many days do I need to spend in Bulgaria to be tax resident?
More than 183 days in any 12-month period. The window rolls, so it can straddle two calendar years. You can also be resident with fewer days if your permanent address or your centre of vital interests is in Bulgaria. Days are counted by physical presence, and part days usually count as full days.
Can I be resident in Bulgaria and another country at the same time?
Yes, under domestic law that is common. The double tax treaty between the two countries then decides which one counts as your residence for treaty purposes. The tie-breaker looks at your permanent home, centre of vital interests, habitual abode and nationality, in that order.
Does a Bulgarian residence permit make me tax resident?
Not by itself. A residence permit is an immigration document. Tax residence depends on the PITA tests: address, days, vital interests or state posting. In practice, though, holding a long-term permit, a lease and a local business usually adds up to residence. Keep both files consistent.
Do non-residents have to file a Bulgarian tax return?
Usually not, because most Bulgarian income paid to non-residents is taxed by withholding at source. You may need to file if you receive income where no withholding applies, such as rent paid by an individual. EU residents can also file to have tax recalculated when it is more favourable.
How do I get a certificate of tax residence in Bulgaria?
Apply to the NRA, online with an electronic signature or at your territorial office. You state the year and the country where you will use it. The certificate confirms your residence under Bulgarian law and, if requested, under the relevant treaty. Processing usually takes a few weeks.
Does Bulgaria have an exit tax for individuals?
No. Bulgaria does not tax unrealised gains when an individual leaves. You simply stop being taxed on worldwide income once you stop meeting the tests. Companies moving assets or their seat abroad can face an exit tax under EU anti-avoidance rules, which is a separate matter.
