According to TV2, a Danish couple recently won an appeal involving a disputed transfer of around 330,000 kroner in business profit between spouses, but their victory rested on a little-known technical requirement: they had to prove they were formally cohabiting on 31 December of the tax year, a detail that determines whether large sums can be transferred or denied by SKAT.
The case highlights how Denmark’s spouse-based tax planning rules depend on fine print that many internationals miss. Under the medarbejdende ægtefælle mechanism, one spouse can receive up to 295,900 kroner of the other’s business profit in 2026, but only if both are formally married and samlevende at year-end. If the cohabitation condition is not met, SKAT can deny the transfer and correct the tax assessment. The couple in question cleared both hurdles. Many do not.
Why 330,000 Kroner Matters More Than Ever
Amounts around 300,000 to 330,000 kroner now sit close to the legal cap, inviting close scrutiny from SKAT. According to Skatteministeriet and Dinero, the cap has risen by about 8.9% between 2024 and 2026, from 271,800 kroner to 295,900 kroner, in line with tax indexation. Meanwhile Denmark’s top tax threshold in 2026 is 777,900 kroner. Shifting profit between spouses can keep both partners under that line, avoiding the extra marginal bite.
For small business owners, the math is compelling. But the rules are unforgiving. According to Dinero, SKAT requires documented proof that the receiving spouse actually worked in the business, at least three to four hours daily, with income matching the real work contribution.
The Samliv Trap for Cross-Border Couples
The requirement that spouses be samlevende on 31 December can be particularly challenging for internationals. One spouse may work abroad for months. Another may commute weekly across the Øresund. According to Hulgaard Advokater, full Danish tax liability continues as long as a year-round home remains available in Denmark and the couple maintains a joint household. But if SKAT decides the cohabitation is genuinely broken, the entire transfer can be denied.
A 2013 parliamentary answer from the Tax Ministry spelled it out clearly. Transfer of unused personal allowance or deficits between spouses only works if they are cohabiting at year-end. The same logic governs medarbejdende ægtefælle. Live apart for work? Document it. Sell the Danish home? Expect your tax residence to shift.
Residence Rules That Bind Without Warning
Denmark’s six-month rule can pull an internationally mobile spouse into full tax liability through presence alone, even without formal residence. The so-called tourist rule delays liability for some students and visitors until 365 days over two years, but starting a business or taking a job triggers full taxation immediately. For a couple managing mortgage refinancing, cross-border consulting work, and a 300,000 kroner profit transfer, these thresholds are landmines.
Compared to Sweden, where spousal sharing of business income generally relies on partnership or employment structures, Denmark’s medarbejdende ægtefælle rule offers a distinct working-spouse mechanism. It is also unusually technical. Detailed technical guidance on medarbejdende ægtefælle and samliv is primarily available in Danish, and typical English overviews do not cover the samliv condition or exact caps.
What Expats Should Do Now
Couples using spouse transfers must document cohabitation status and work contributions before filing. If one partner spends significant time abroad, clarify with SKAT or an advisor whether your samliv is considered intact. For many spouse-transfer mechanisms, both spouses typically need to be fully tax-liable to Denmark. Limited tax liability or certain cross-border statuses can restrict transfers, and specialist advice is often needed.
If SKAT denies a large transfer, appeal through Skatteankestyrelsen and if necessary Landsskatteretten. According to TV2, the couple in the recent case won because they met the formal tests. Tax advisers report that some internationals only discover these requirements after a reassessment, including in cases involving large amounts. The lesson is clear: in Denmark, tax planning for married couples is generous, but only if you live where the law says you live on the one day that counts.
