If you are moving to Bulgaria in November or December 2026, stay, and have spent no other days in Bulgaria earlier in 2026, the 183-day rule will not make you a Bulgarian tax resident for 2026. In the typical case your first Bulgarian tax year is 2027. That is the short answer to “when do I become tax resident in Bulgaria” after a late-year move, and it follows from the wording of Art. 4 of the Personal Income Tax Act (PITA, in Bulgarian ЗДДФЛ) as of 2026. The typical case has three exceptions that matter in practice: days you already spent in Bulgaria earlier in 2026, a centre of vital interests that has moved here before 31 December, and a double tax treaty that settles the overlap with your old country. Below we apply each Art. 4 test to a Q4 arrival, run the dates, and map what to file in Bulgaria for 2026 and for 2027.
Moving to Bulgaria in November or December 2026: the short answer is usually 2027
Bulgaria assigns residence one calendar year at a time. Art. 15 PITA defines the tax year as the calendar year. Art. 4(2) adds the rule that decides most Q4 cases: for the day test, a person is resident “for the year in which the stay exceeds 183 days”. If you arrive on 15 November 2026, the most you can spend in Bulgaria before 31 December is 47 days. The 183-day line is crossed in 2027, so the day test makes you resident for 2027, not 2026.
The other tests in Art. 4 can change that answer, so here is the quick version before the detail:
| Your situation | Likely first Bulgarian tax year | Why |
|---|---|---|
| Arrive in November or December 2026, no earlier Bulgarian days, family and work abroad until the move | 2027 | The 183-day count is exceeded only in 2027 (Art. 4(2)) |
| Arrive in November 2026 after spending 140 days in Bulgaria earlier in 2026 | Possibly 2026 | The 12-month window can pass 183 days before 31 December |
| Arrive in December 2026 with spouse, children, home and job all moved | 2026 is arguable | The centre of vital interests test (Art. 4(1)(4)) has no day threshold; a treaty decides any overlap with your old country |
| Arrive in early January 2027 | 2027, unless earlier 2026 days already exceed 183 in a 12-month window | Days spent in Bulgaria earlier in 2026 still count; if they pass 183 in a 12-month window ending in 2026, you are resident for 2026 (Art. 4(1)(2), 4(2)) |
Which year makes you a Bulgarian tax resident? The four Art. 4 tests
For most people moving in November or December 2026, the answer is 2027. Only the day test with earlier 2026 days, or the centre of vital interests, can make it 2026. Art. 4(1) PITA makes a person resident, regardless of nationality, if any one of four tests is met. The National Revenue Agency (NRA) page on local and foreign persons sets out the same four tests. Here is how each one behaves when the move happens in the last weeks of 2026:
| Test (PITA) | What the law says | Q4 2026 arrival: 2026 | Q4 2026 arrival: 2027 |
|---|---|---|---|
| 1. Permanent address Art. 4(1)(1), 4(5) | A permanent address in Bulgaria, but not if the centre of vital interests is outside Bulgaria | Does not decide the year by itself | Counts only together with test 4 |
| 2. Day test Art. 4(1)(2), 4(2), 4(3) | More than 183 days in each 12-month period; resident for the year in which 183 days are exceeded | Usually not met, unless you had earlier 2026 days | Met once day 184 is reached |
| 3. State assignment Art. 4(1)(3) | Sent abroad by the Bulgarian state, its bodies or a Bulgarian enterprise, plus family members | Not relevant to incoming foreigners | Not relevant |
| 4. Centre of vital interests Art. 4(1)(4), 4(4) | Interests closely connected with Bulgaria: family, property, place of work or business, place from which property is managed | Possible, depending on the facts on the ground | Usually met once you live here |
Two points are easy to miss. First, the address test is weaker than it looks: Art. 4(5) says a person with a Bulgarian permanent address is not resident if their centre of vital interests is outside the country. Registering an address in December does not, on its own, make you a 2026 resident. Our guide to address registration for foreigners covers the paperwork side. Second, the centre of vital interests test carries no minimum stay. That is why it, and not the day count, is the test that can pull 2026 into Bulgaria.

183-day rule in your year of arrival: worked dates for late-2026 moves
The day test counts physical presence in Bulgaria. Under Art. 4(2), the day you enter and the day you leave each count as a day in Bulgaria. Under Art. 4(3), a stay solely for education or medical treatment does not count. The window is “each 12-month period”, so it can straddle 31 December. The resulting residence attaches to the calendar year in which the 184th day falls.
The table assumes continuous presence after arrival and no excluded days. February 2027 has 28 days.
| Arrival and earlier days | Bulgarian days in 2026 | 184th day in the window | Resident year under the day test |
|---|---|---|---|
| 15 November 2026, no earlier visits | 47 | 17 May 2027 | 2027 |
| 1 December 2026, no earlier visits | 31 | 2 June 2027 | 2027 |
| 2 January 2027, no earlier visits | 0 | 4 July 2027 | 2027 |
| 1 November 2026, after 140 days in Bulgaria between March and July 2026 | 201 | 14 December 2026 | 2026 |
The standard case: arrival on 15 November 2026
Arriving on 15 November and staying gives 16 days in November and 31 in December: 47 days in 2026. On 1 January 2027 you are on day 48 of the window, and day 184 falls on 17 May 2027. Because the threshold is crossed in 2027, the day test makes you resident for 2027. A December arrival only moves the date later, to 2 June 2027 for a 1 December arrival. If you wait until 2 January 2027, the 184th day is 4 July 2027, and the resident year under the day test is still 2027.
The trap: scouting trips earlier in 2026
Many Q4 movers spend weeks in Bulgaria earlier in the year: house-hunting, school visits, a summer on the coast. Those days count. Take 140 days in Bulgaria between March and July 2026, then a permanent move on 1 November 2026. You need 44 more days to pass 183, and you reach them on 14 December 2026. The 12-month window ending that day (15 December 2025 to 14 December 2026) contains all the earlier visits. The threshold is crossed in 2026, so under Art. 4(2) you are resident for 2026. If your old country also treats you as resident for 2026, the treaty questions below apply from 2026, not 2027.
Count before you book. Pull your 2026 travel records before you fix the move date. Each trip’s arrival and departure day counts as a full Bulgarian day under Art. 4(2), so frequent short trips add up faster than people expect.

Your first tax year in Bulgaria: why there is no split year
Readers coming from the UK often expect a “split year”, with residence starting on the day they arrive. Bulgarian domestic law has no such rule as of 2026. Two provisions point the same way:
- Art. 4(2) PITA makes a person resident “for the year” in which the stay exceeds 183 days, not from a date.
- Art. 15 PITA defines the tax year as the calendar year.
Status matters because of what follows from it. A resident is taxed on income from Bulgarian and foreign sources (Art. 6 PITA). A non-resident is taxed only on Bulgarian-source income (Art. 7 PITA). The general rate on the annual tax base is 10% (Art. 48(1) PITA, as of 2026). So the question “2026 or 2027?” is really the question of which year’s worldwide income Bulgaria can claim.
What this means in practice: do not plan around Bulgarian residence “from 15 November”. Domestic law looks at the whole year. Whether part of that year is allocated back to your old country is decided by the double tax treaty, if there is one. We cover this below.
Can the centre of vital interests make you resident for 2026?
Usually not for a late-year move, but it can if your family, home and work have all moved to Bulgaria before 31 December 2026. The test has no day threshold (Art. 4(4) PITA).
Art. 4(4) PITA places your centre of vital interests in Bulgaria when your interests are closely connected with the country. The factors it lists are your family, your property, the place from which you carry out employment, professional or business activity, and the place from which you manage your property. There is no day count and no reference to a part of the year. Our centre of vital interests guide goes through each factor.
Our assessment, not a statutory rule: for most people who move in the last six or eight weeks of the year, the facts for 2026 as a whole still sit mainly in the old country. That covers where the family lived, where the salary was earned and where the home was. On those facts the centre of vital interests test is unlikely to make 2026 a Bulgarian year. The picture changes when everything moves at once. Picture an illustrative family that arrives on 1 December 2026, has sold the old home, has enrolled the children in a Bulgarian school and starts Bulgarian employment the same month. Bulgaria could argue that their centre of vital interests was here by the end of 2026. Because the tax year is the calendar year (Art. 15 PITA) and Bulgarian law has no split-year rule, the NRA could then treat them as resident for 2026.
That is not automatically bad news. The family is likely resident in its old country for 2026 as well, and a double tax treaty would then decide which country counts. But it changes what has to be filed and documented in Bulgaria, so it should be a deliberate decision and not a surprise.
When the treaty tie-breaker decides the year
Domestic law gives only half of the answer. Your old country applies its own residence rules, and for most Q4 movers it still treats them as resident for most or all of 2026. If Bulgaria also treats you as resident for 2026, through earlier days or the centre of vital interests, you are resident in both countries under domestic law. The double tax treaty between them then decides which one counts as your state of residence for treaty purposes.
Treaties that follow the OECD Model use a fixed order for individuals. In the 2015 UK–Bulgaria convention it sits in Article 4(3), in the text published by the UK government:
- Permanent home. You are resident only in the state where you have a permanent home available to you.
- Centre of vital interests. If you have a permanent home in both states, the state with which your personal and economic relations are closer decides.
- Habitual abode. If that cannot be determined, or you have no permanent home in either state, the state of your habitual abode decides.
- Nationality. If you have a habitual abode in both states or in neither, the state of which you are a national decides.
- Mutual agreement. If you are a national of both or of neither, the two tax authorities settle it by mutual agreement.
For a late-year mover, the first step usually carries the weight. In our reading, if a home in your old country was available to you for most of 2026 and nothing comparable existed in Bulgaria until November, the treaty will usually point to the old country for that period. Whether a treaty lets the two administrations divide 2026 by date (old country until the move, Bulgaria after it) depends on the treaty and on how both administrations apply it. Bulgarian domestic law does not provide for it. Each treaty has its own wording, so check yours in our overview of Bulgaria’s double tax treaties. For the first step in more depth, see our analysis of the permanent home test.

What to file in Bulgaria for 2026 vs 2027
Once the year is clear, the filing follows from the PITA as of 2026. The annual return is filed between 10 January and 30 April of the following year (Art. 53(1)). Traders under Art. 51(1), including sole traders, file between 1 March and 30 June.
| Your status | 2026 in Bulgaria | 2027 in Bulgaria |
|---|---|---|
| Non-resident in 2026, resident from 2027 (the standard Q4 case) | Bulgarian-source income only (Art. 7). With no Bulgarian-source income, usually nothing to declare | Worldwide income. Return between 10 January and 30 April 2028 |
| Resident in 2026 (earlier days or centre of vital interests) | Worldwide income for 2026. Return between 10 January and 30 April 2027, with evidence of foreign tax paid (Art. 50(5)) and treaty relief where it applies | Worldwide income. Return between 10 January and 30 April 2028 |
Two details catch first-year residents. Art. 50(1)(4) requires residents to declare shares and holdings in companies, places of business, fixed bases and real estate abroad. Art. 52(2) keeps that filing duty in place even for someone whose only income is a Bulgarian salary that would otherwise exempt them from filing. If you arrive with a foreign portfolio or a home you have kept abroad, expect to file in your first resident year. Our annual tax filing guide walks through the return itself.
Moving to Bulgaria before 1 January: a five-step checklist
- Count every Bulgarian day, including every arrival and departure day, back to early January 2025: a 12-month window that ends in 2026 can start that early.
- Map your position on 31 December 2026: where your family lives, where your home is, where you work, and where you manage your assets from.
- Check your old country’s rule for the year of departure and the treaty tie-breaker that applies between it and Bulgaria.
- Keep presence evidence from day one: tickets, lease, utility bills, school and employment records. You will need it for the day count and for the tie-breaker.
- Diarise the first Bulgarian return: 30 April 2027 if 2026 is a resident year, 30 April 2028 if 2027 is your first. Traders under Art. 51(1), including sole traders, have until 30 June.
This is the process. We handle every step on the Bulgarian side — here is how to get started.
Lining up the end of residency in your old country
Bulgaria’s calendar-year approach does not have to match the rules of the country you are leaving. The UK is the clearest example of a country that can split the year of departure. Under split year treatment in the statutory residence test, HMRC’s manual (RFIG21130, Case 3) sets these conditions for someone who ceases to have a UK home:
- UK resident in the tax year and the previous one, and non-UK resident in the following tax year;
- a UK home at the start of the tax year, which they then cease to have for the rest of that year;
- fewer than 16 days in the UK from that point; and
- within six months, becoming tax resident in the new country, being present there at the end of each day for six months, or having their only home or all their homes there.
The timing detail matters for a November move. If you cease to have a UK home on 15 November 2026, the six-month period ends in mid-May 2027. Bulgaria treats you as resident for the whole of 2027, but the day count that triggers it is only crossed on 17 May 2027 in our first example, just after the six-month window. Whether HMRC accepts that for Case 3 is a UK question; confirm it, and the exact end date, with your UK adviser. The other two limbs (being present in Bulgaria at the end of each day for six months, or having your only home or all your homes there) do not depend on the Bulgarian count. Our UK split year timeline takes the UK side month by month.
Other countries have their own rules for the year of departure. Our guide to deregistering tax residency in your home country covers the practical exit steps. For the documents the other side will ask for, see our guide to the NRA tax residency certificate. Ask early which period a certificate can cover in your year of arrival.
Moving to Bulgaria before 1 January or after: how to decide
On the day test alone, a November or December 2026 arrival and an early January 2027 arrival usually lead to the same first Bulgarian tax year, 2027. The real differences lie elsewhere:
| Factor | Arrive Nov/Dec 2026 | Arrive early Jan 2027 |
|---|---|---|
| 184th day under the day test (continuous stay) | 17 May or 2 June 2027 in our examples | 4 July 2027 for a 2 January arrival |
| Risk that Bulgaria claims 2026 | Higher if you had earlier 2026 days or move family, home and work before 31 December | Lower; only earlier Bulgarian days, or family, home and work already in Bulgaria before 31 December, can bring 2026 into play |
| Building the Bulgarian record for 2027 | Address, lease and accounts in place before 2027 starts | Built during 2027 |
| Large income events in late 2026 (share sale, bonus) | Need checking against both countries’ claims for 2026 | Usually stay with the old country for 2026 |
None of this is a recommendation for or against a December move. It shows where the decision really sits: in your earlier days, your 31 December facts, your income calendar and your old country’s departure rules.
Common questions before booking:
Is this lawful? Choosing a move date with the Art. 4 PITA tests in mind is lawful planning. What matters is that the facts you declare match the facts on the ground.
Do I need to speak Bulgarian? No. We handle all interactions with the Migration Directorate, notaries, and other authorities in Bulgarian on your behalf. All communication with you is in English.
What does it cost? The first consultation is free.
Will my home country still tax me for 2026? Usually, yes, for at least part of the year. We work with your adviser in your country to line up the timing and the documents on both sides. The final position depends on the treaty and on both tax administrations.
The bottom line
So, if you are moving to Bulgaria in November or December 2026, when do you become tax resident? Under the day test, and with no earlier Bulgarian days in 2026, in 2027: the 184th day falls between early May and early July 2027 depending on your arrival date (17 May for a 15 November arrival, 2 June for 1 December), and Bulgaria assigns residence to that whole calendar year. Earlier Bulgarian days in 2026 can move the answer back to 2026, and so can a centre of vital interests that has fully moved before 31 December. If your old country still claims you for that year, the treaty tie-breaker decides. Settle these points before you fix the move date, not when the first return is due.
