Sweden

Sweden is an EU member state whose rules on unlimited tax liability are based on three alternative domestic criteria: actual residence in Sweden, habitual or permanent stay in Sweden, or an essential connection with Sweden after previously having been resident there. Unlike many jurisdictions, Sweden does not use a general 183-day residence test. Immigration residence remains a separate process.

Informational overview of domestic tax-residency and residence rules.

Tax residency

Under Chapter 3 of the Swedish Income Tax Act (Inkomstskattelagen), an individual is subject to unlimited tax liability if they are resident in Sweden, stay in Sweden on a permanent basis, or retain an essential connection with Sweden after previously being resident there.

Where an individual is also treated as resident in another jurisdiction, the applicable double tax treaty may determine treaty residence through its tie-breaker provisions.

Actual residence (bosatt i Sverige): this criterion concerns where the individual has their actual and lasting home. Skatteverket considers factors such as population registration and where the individual regularly spends their overnight rest. Population registration is relevant evidence but does not by itself determine tax residence.
Habitual or permanent stay (stadigvarande vistelse): a sufficiently continuous stay in Sweden may create unlimited tax liability even without a permanent home there. A stay of six consecutive months or more will normally qualify, provided the individual generally spends their overnight rest in Sweden. Temporary interruptions abroad do not necessarily break the period, while daily commuting into Sweden without overnight stays does not normally qualify. Periods shorter than six consecutive months may also qualify where the stays are sufficiently extensive and regular, based on the overall pattern of presence.
Essential connection (väsentlig anknytning): a person who has previously lived in Sweden may remain subject to unlimited tax liability after departure if they retain sufficiently strong connections with Sweden. Relevant factors include Swedish citizenship, length of previous residence, family in Sweden, a dwelling available for year-round use, Swedish real estate, business activities or substantial influence over a Swedish business, and whether the individual has established a permanent home abroad. During the first five years after departure, a Swedish citizen, or an individual who previously lived or permanently stayed in Sweden for at least ten years, generally bears the burden of showing that no essential connection remains. This five-year rule is a presumption concerning the existence of an essential connection, not a separate residence test or an automatic five-year continuation of Swedish tax residence.

Day counting

Actual residence: no fixed day-count threshold applies. The assessment is based on the individual's actual and lasting home and factual pattern of residence.
Habitual or permanent stay: there is no 183-day calendar-year test. A stay of at least six consecutive months will normally qualify, and the period may extend across two calendar years. Overnight stays are generally required. Temporary periods abroad may be disregarded where they do not break the continuity of the stay. Where individual periods are shorter than six months, there is no fixed safe day threshold and the length, extent and regularity of the recurring stays must be assessed together.
Essential connection: no minimum physical-presence threshold applies. The test is based on the individual's continuing personal and economic connections with Sweden rather than the number of days spent there. The five-year presumption after departure concerns the burden of proof and does not create a separate day-count rule.

Tax consequences

Individuals with unlimited tax liability are generally taxable in Sweden on their worldwide income, subject to applicable double taxation agreements. Individuals with limited tax liability are generally taxable only on specified categories of Swedish-source income.

Non-residents working in Sweden may, depending on the circumstances, be taxed under the Special Income Tax for Non-Residents (SINK).

Migration / EU residence

EU/EEA citizens may live and work in Sweden where they satisfy the applicable right-of-residence conditions.

A person intending to live in Sweden for at least one year should generally be entered in the Swedish Population Register and will normally receive a Swedish personal identity number.

Population registration, a personal identity number, a coordination number or an immigration permit does not by itself determine unlimited tax liability.
