Sweden Tax Residency (6-month habitual stay rule)

Key parameters
Threshold	6 consecutive months
Period / Window	Continuous stay, not a calendar year
Counting	Elapsed time, short absences ignored
Alternative	Residence, essential connection
Additional requirements	Liability can survive departure

Sweden reaches unlimited tax liability by 3 alternative routes, and only one of them involves counting time:

• Habitual stay — being in Sweden for 6 consecutive months or more. Short departures, including trips home, do not shorten the stay, so the clock runs on elapsed time rather than on days actually present.
• Residence — genuinely living in Sweden, judged on your circumstances rather than a threshold.
• Essential connection — retaining significant ties after moving away, such as a home, family, or substantial assets still in Sweden.

Sweden's day rule is unusual. Most countries count days and reset annually. Sweden measures a continuous period, which means a stay is assessed by when it started and ended rather than by adding up the days inside it.

The essential connection limb is the one that catches people leaving. Moving abroad does not end Swedish liability by itself if a home or family remains behind, and the connection is presumed to persist for a period after departure unless you can show otherwise.

This is due to change. A government proposal would replace the 6-month test with a fixed count of overnight stays — more than 160 in a calendar year, or more than 120 in each of 2 consecutive years — planned to take effect 1 January 2027. Until then, the 6-consecutive-month test above is what applies.

• Leaving for a while doesn't restart the clock. Because short absences are disregarded, a pattern of weekend trips home during a long stay does nothing to break the 6-month period.
• Liability can survive your departure. An essential connection to Sweden — most often a retained home or family still living there — can keep unlimited liability running after you have moved abroad.
• The 2027 change exists because "6 months" kept ending up in court. The current test has no statutory day figure at all, and years of disputes over what counts as a genuinely continuous stay are the stated reason for replacing it with a fixed count.
• Unlimited liability is not the same as paying tax on everything. Treaty relief and foreign tax credits can reduce what Sweden actually collects, but the liability itself attaches first.
• Sweden has a separate regime for short-term foreign workers, taxed at a flat rate on Swedish income. That is a method of taxation rather than a residency test, and the tests above run underneath it.

Unlimited liability reaches worldwide income while limited liability covers only Swedish-source income, so a misjudged position usually surfaces as foreign earnings left undeclared — and the essential-connection limb means the exposure can continue after you believe you have left. Skatteverket imposes a tax surcharge on income that was not correctly reported, calculated as a percentage of the tax avoided, and interest accrues on unpaid amounts from the original due date. Professional tax advice is strongly recommended in situations like this.

A contract that runs past six months

You take a 7-month assignment in Stockholm beginning in March, flying home for a long weekend roughly every month. Those short absences do not shorten the stay, so the 6-month habitual stay is established and unlimited liability follows.

A stay deliberately kept short

You work in Gothenburg for 5 months and then leave for good, keeping no home or family in Sweden. The stay falls short of 6 consecutive months and no connection remains, so unlimited liability is not triggered.

A move abroad that leaves ties behind

You relocate to Spain but keep your Swedish house available and your family stays through the school year. Your day count in Sweden collapses, but the essential connection can keep unlimited liability running after your departure.
