Serbia Tax Residency: Why 183 Days Is Not the Only Test

Serbia tax residency: two tests, not one deadline

Serbia’s personal income tax rules give two alternative routes to residence. Under Article 7 of the Personal Income Tax Law (opens in a new tab), which the Tax Administration also publishes in English (opens in a new tab), you are resident if either test applies:

The Tax Administration’s annual personal income tax guide (opens in a new tab) states the same two tests. The first row is why “I will stay for only five months” is not a complete tax plan. Equally, buying an apartment does not by itself settle where your domicile is: the facts of your life do.

Keep the immigration decision separate: our Serbia residency guide covers the permits to live and work there, and this article is its tax companion, on when that move can make you resident for tax.

The presence test does not reset in January

The window is any 12-month period that begins or ends in the tax year, not simply January to December. Article 7 also counts part of a day in Serbia as a full day, so the days you arrive and leave count, except part of a day spent in transit through Serbia. A spreadsheet that records only nights can therefore miss days that matter.

Build a dated entry and exit record, then examine the rolling windows. Mark transit days separately: the law does not count part of a day spent in transit through Serbia, but it does not define transit, so keep the evidence for each one. If your travel changes, update the record before relying on an earlier conclusion.

Do not assume residence starts when the count is reached

Article 7 also has specific arrival and departure rules. If you know on your first entry that you will meet either test, the law treats you as resident from that first entry.

• Arrival: if you were not resident in the year before the year you arrive, you are not treated as resident for the part of the arrival year before your first entry, as long as you did not meet the domicile or center-of-interests test in that part of the year.
• Final departure: if you are not resident in the year after the year you finally leave, you are not treated as resident for the part of the departure year after you leave, as long as you do not meet the domicile or center-of-interests test in that part of the year.

The arrival rule excludes only the part of the year before your first entry, so reaching the day count later does not automatically make the first 182 days irrelevant, and the departure rule has its own condition, so a flight out of Serbia does not automatically end residence while qualifying ties remain.

Resident and nonresident do not mean taxed and untaxed

Serbian residents fall within the law’s scope for income earned in Serbia and abroad. Nonresidents can still be liable on income earned in Serbia: Article 8 names income from work performed in Serbia. A foreign payer or a payment into a foreign account is therefore not enough to dismiss the Serbian question.

One exemption is specific: if you are a nonresident and spend no more than 90 days in Serbia in a 12-month period that begins or ends in the tax year, income from a nonresident principal with no business or activity in Serbia is exempt. The exemption also covers a nonresident principal that does business in Serbia, as long as your service does not serve that Serbian business (Article 9b).

This is a starting point, not a calculation of tax due: income categories, other exemptions and a treaty can change the treatment, so identify where the work happens and what the payment represents.

If two countries claim you, check the actual treaty

Domestic residence and treaty residence are different stages of the analysis. First establish each country’s domestic position. Then check whether a treaty is in force between the two countries and how it applies to your facts and income.

For example, Article 4(2) of the convention between the UK and Serbia (opens in a new tab), which HM Revenue and Customs lists as in force (opens in a new tab), resolves an individual’s dual residence in order: a permanent home; if there is one in both countries, closer personal and economic relations; then habitual abode; then nationality; and finally agreement between the two tax authorities. It is not a rule that lets you simply choose the lower-tax country.

This is a UK-specific illustration, not a conclusion for every nationality or country. Serbia’s Ministry of Finance keeps a country-by-country treaty directory (opens in a new tab). A treaty residence conclusion also does not mean every income source becomes exempt everywhere.

Separately, Article 12 of Serbia’s domestic law gives a Serbian resident a credit for income tax paid abroad on foreign income, capped at the Serbian tax that law would charge on the same foreign income. “I paid tax abroad” and “nothing remains to do in Serbia” are not interchangeable statements.

If a payer abroad asks you to prove Serbian residence under a treaty, the Tax Administration issues a certificate of residence on Form POR-1, under the rulebook on certificates of residence (opens in a new tab), unless the other country requires its own form. Each country issues its certificate under its own rules: our guide to the UAE tax residency certificate shows how the UAE’s Federal Tax Authority does it.

Build an evidence file before the move

The useful output is a documented timeline, not a guessed resident or nonresident label. Organize these materials:

• Travel: entry and exit dates, supporting tickets or records, and clearly identified transit days.
• Homes and household: where accommodation is available and where your household actually lives, with dates when arrangements change.
• Work and business: where activities are performed, your contractual arrangements and the location of continuing responsibilities.
• Other country: its domestic residence assessment, any residence certificate and the treaty being considered.
• Income and foreign tax: income categories, periods earned, tax assessments and evidence of payment.
• Serbian certificate: a certificate of residence on Form POR-1, if you need to prove Serbian residence to a payer abroad.

This is a practical preparation list, not an official or complete list of required documents. If you are moving with your household, fit it into our guide to moving abroad with family, so the tax review happens before important changes, not after the first filing surprise.

Plan the move, the ties and the calendar together

Serbia’s 183-day test matters, but it is neither the only residence trigger nor a universal tax-free allowance. Write down the test you expect to meet and from when, the record behind it, and what remains open in the other country.
