Øresund 50% rule: home-working examples for 2026

The 2025+ Øresund rule requires at least half the working time in Denmark during each rolling twelve-month period for qualifying Swedish-resident employees. In an equal-length five-day week, 0–2 Swedish home-working days leave at least 60% in Denmark; 3–5 leave less than 50%. The latter patterns need normal tax allocation, not automatic taxation of everything in Sweden.

Six regular-week examples

The table assumes the same five equal-length workdays every week, a qualifying Danish employment relationship and no other circumstances that change the test. Its salary shares illustrate active work location when the agreement is not met; they are not final annual taxable amounts.

How rolling twelve-month periods change the answer

The authority’s test is not simply January through December. Relevant windows can straddle income years. A recent long block of Swedish remote work can matter even if the usual weekly schedule is mainly Danish.

SKAT’s 2025 allocation tool requests a longer work history to examine the periods around the income year. Use that tool and the current instructions for your specific reporting year rather than extrapolating an answer from this table.

Working time, days, holidays and partial days

The treaty wording and official overview guidance use working time. Øresunddirekt’s practical explanation uses workday counts, including holidays and sick leave as Danish days and counting a partial Danish day as a whole Danish day.

This means a split day is not automatically a proportional half-day in the eligibility test. For uneven shifts, leave, mixed employers or irregular travel, consult the detailed rules. The calculator has no day-by-day history and cannot perform that calendar assessment.

Below 50% does not mean 100% Swedish tax

When the agreement conditions fail, work physically performed in Denmark and Sweden can need separate salary allocation. The active-work split and treaty rules determine the position. There can also be employer reporting and withholding consequences.

Keep income-tax allocation separate from social insurance. A schedule that passes the Øresund test can still require a different A1 outcome; the calculator’s weekly labels cannot replace an authority decision.

Common questions

Is exactly 50% enough?

The detailed agreement guidance states at least half. Exactly half must still be assessed with the applicable counting rules and other conditions.

Does three WFH days mean all salary is Swedish-taxed?

No. Under the equal-day illustration, two Danish workdays leave a Danish salary share. Actual allocation needs your records.
