Denmark’s Tax Cuts Hide Mortgage and Salary Traps

Denmark’s new government is cutting headline tax rates but quietly raising real taxes through a two-year freeze on allowances and a cap on mortgage interest deductions, hitting both Danes and expats with big loans or rising salaries.

The new coalition’s tax package looks generous on paper. The top-top tax on incomes above roughly 2.6 million kroner disappears. Company tax drops from 22 to 19 percent over three years. VAT on fruit and vegetables vanishes, and the share-savings account ceiling triples to 500,000 kroner. If you work in tech or finance in Copenhagen, that sounds like good news.

But buried in the fine print is a different story. The government will freeze key tax thresholds and allowances for two years. No adjustment for inflation. No increase in the personal allowance or the employment deduction. The top-tax threshold stays put at around 777,900 kroner while salaries and bonuses keep climbing. That means more of your income gets taxed at higher rates without any formal rate increase. Economists call it bracket creep. I call it a stealth tax hike.

The mortgage trap

The second hidden blow lands on homeowners. Denmark will introduce a new cap on deductible mortgage interest: 150,000 kroner per year for singles, 300,000 for couples. Right now there is no limit at all. If you bought an apartment in Østerbro or Aarhus C in the last few years, you probably borrowed heavily. Interest rates have come down but many people still pay well over the new ceiling. That deduction has been one of the few things softening Denmark’s punishing cost of living. Losing it will hurt.

Expats on the 27 percent flat-tax scheme get partial shelter on salary. But that scheme does not cover investment income, property gains, or interest deductions. If you are on ordinary Danish tax, you face the same squeeze as everyone else, often with the added complexity of cross-border mortgages or foreign pension plans.

Who wins and who loses

The government argues the package will create 35,000 new full-time jobs by 2035 and simplify personal tax. Business groups praise the company tax cut and better terms for stock options. Higher share-income thresholds and the expanded share-savings account do help if you invest in equities. Denmark is trying to compete with Sweden and the Netherlands for talent and capital.

Critics see it differently. A March 2026 analysis by liberal think tank CEPOS found that earlier tax changes under Mette Frederiksen reduced disposable income by 1.7 percent for the bottom tenth of earners, compared with just 0.6 percent for the top tenth. The new package risks repeating that pattern. The interest-deduction cap hits younger families and leveraged households hardest. The threshold freeze drags more middle-income earners into the top bracket, which still sits at around 56 percent including the labour-market contribution.

What expats should do now

First, calculate your mortgage interest. If it exceeds 150,000 or 300,000 kroner per year, look at refinancing or accelerating principal repayment. Second, if you expect salary growth or a bonus, estimate whether you will cross the top-tax threshold and how much that will cost. Third, review your investment structure. Moving listed shares into an aktiesparekonto up to the new 500,000-kroner limit can simplify tax and reduce your rate on gains.

The government is also setting up a commission to design a new tax on realised housing gains, paired with lower property tax. Details are vague but the promise is no tax on gains you have already made. If you plan to sell and leave Denmark in the next few years, follow that process closely. Timing could matter.

The bigger picture

Denmark remains one of the highest-tax countries in the OECD. That has not changed. What has changed is the mix. Over the past two decades, tax reforms have shifted the burden from high earners and capital toward consumption and hidden mechanisms like frozen thresholds and capped deductions. An analysis by the Economic Council of the Labour Movement in March found that many low and middle earners have effectively lost out, while the richest gained more disposable income.

For expats, the trade-off endures. You pay a lot but you get efficient public services, strong labour protections, and a functioning welfare state. The new package tilts slightly toward business and investors. But if you carry a big mortgage or your salary is climbing, the hidden tax increases will land on you first. The government calls it simplification. It feels more like sleight of hand.
