Checked against the OECD Bulgaria tax residency profile on July 23, 2026.
Bulgaria's tax-residence day count should not be treated as a simple January-to-December shortcut.
Short answer: the OECD Bulgaria tax residency profile lists more than 183 days in each twelve-month period as one individual tax-residence criterion. It also lists permanent address, assignment abroad by Bulgarian state or enterprise, and center of vital interests criteria. Track Bulgaria days carefully, but do not reduce the tax-residence question to one number.

What does Bulgaria's 183-day rule say?
The OECD Bulgaria tax residency profile says Bulgaria's individual tax-residence criteria are tied to Article 4 of the Income Taxes on Natural Persons Act.
For individuals, the profile lists several possible criteria:
| Criterion | What to record |
|---|---|
| Permanent address in Bulgaria | Address records and whether it looks like an available base |
| More than 183 days in each twelve-month period | Every Bulgaria entry and departure date |
| Assignment abroad by Bulgarian state, authorities, organizations, or enterprise | Assignment documents, if relevant |
| Center of vital interests in Bulgaria | Family, property, work, business, and property-management facts |
The day count matters, but it is one part of the residence file.
Is Bulgaria's 183-day rule a calendar-year test?
The source wording in the OECD profile is more than 183 days in each twelve-month period.
That is different from a simple calendar-year spreadsheet. A stay that begins in one year and continues into the next can still matter inside a twelve-month review period.
Track:
- each arrival in Bulgaria
- each departure from Bulgaria
- ongoing stays
- repeat trips inside every twelve-month span
- documents that explain the reason for the stay
- advisor notes if you are close to the threshold
If you are approaching 183 days, do not wait until December to rebuild the count.
Does Bulgaria count arrival and departure days?
The OECD profile says entry and leaving days are regarded separately as days of stay in Bulgaria.
That means partial travel days can matter in the record. If you arrive late at night, record the arrival date. If you leave early in the morning, record the departure date. Do not compress a trip into nights stayed or hotel dates.
For example:
| Trip record | Why it matters |
|---|---|
| Flight arrival date | May be a Bulgaria stay day |
| Flight departure date | May be a separate Bulgaria stay day |
| Border or boarding evidence | Helps support the date record |
| Accommodation record | Supports where you stayed, but does not replace entry and exit dates |
Use exact dates, not rounded estimates.
Does crossing 183 days automatically decide Bulgarian tax residence?
Do not assume that.
The profile lists more than one criterion. It also says a permanent address in Bulgaria does not make a person Bulgarian resident if the center of vital interests is not in Bulgaria.
Center of vital interests can consider facts such as family, property, employment, professional or business activity, and the place from which property is managed.
The practical point: 183 days is a major recordkeeping threshold, but Bulgarian tax residence can still turn on facts beyond day count.
What about education or medical treatment stays?
The OECD profile says a stay solely for education or medical treatment is not regarded as a period of stay in Bulgaria.
Keep this caveat narrow. Do not turn it into a planning strategy or a broad exclusion for any school, course, hospital visit, or mixed-purpose stay.
If this fact matters to your situation, keep:
- enrollment or treatment documents
- entry and exit records
- purpose-of-stay notes
- professional advice
- source copies checked at the time
This guide does not decide whether a stay qualifies for that caveat.
Does Schengen time matter for Bulgaria tax residence?
Bulgaria is now part of the Schengen Area for short-stay day counting, but Schengen 90/180 and Bulgarian tax residence are separate questions.
A Schengen record asks whether short-stay days fit inside the 90 days in any 180-day window. A Bulgaria tax-residence record asks a different question about Bulgarian presence and other residence criteria.
Keep both records separate:
| Question | Record type |
|---|---|
| Can I stay in Schengen under 90/180? | Schengen short-stay tracker |
| How many days have I spent in Bulgaria? | Bulgaria-specific day record |
| Could Bulgaria tax residence be an issue? | Tax-residence file for advisor review |
Do not use a Schengen calculator as a Bulgaria tax-residence answer.
Where Jetseen fits
Bulgaria is not listed as one of Jetseen's built-in 13 rule types, so use custom trackers and records rather than assuming Bulgaria-specific tax automation.
A practical Bulgaria setup:
- create a custom rolling tracker for Bulgaria
- log every entry and departure date
- attach travel documents and accommodation records
- add notes for work, family, property, or advisor context
- keep Schengen 90/180 in a separate tracker
- export CSV records for your accountant or tax advisor
Jetseen does not determine Bulgarian tax residence, filing obligations, treaty treatment, certificates, or tax due.

FAQ
Is 183 days or fewer always safe in Bulgaria?
No. The source pack does not support that shortcut. Bulgarian tax residence can involve permanent address, center of vital interests, assignment facts, and other details beyond a single day count.
Does Bulgaria use a calendar-year 183-day rule?
The OECD profile says more than 183 days in each twelve-month period. Track rolling twelve-month spans instead of relying only on a January-to-December total.
Does arrival day count in Bulgaria?
The OECD profile says entry and leaving days are regarded separately as days of stay in Bulgaria.
Can Jetseen decide whether I am Bulgarian tax resident?
No. Jetseen can help you track days, notes, documents, reminders, and CSV records. It does not decide tax residence or replace tax advice.
