New interest rates for calculating day-to-day interest for 2023

As 2023 is coming to end, the deadline for payment of taxes related to 2023 without any interests or surcharges applied is as well. This year in particular marks a change due to the general developemnt in interest levels in Denmark. The rate of interest and surcharge has gone up dramatically since last year and it is, therefore, highly worthwhile to consider payment of outstanding taxes before the year comes to an end.

This year, the pro anno interest rate is 5.5% until July 1st 2024, after which The Danish Tax Agency (Skattestyrelsen) will charge a fixed surcharge of 7.5%. Last year, the pro anno rate was 1.7% and the residual tax surcharge was 3.7%.

It is worthwhile to consider paying the residual tax, but of course it depends on the amount of the interest.

Day-to-day interest from January 1st to July 1st 2024

On residual tax paid after January 1st 2024, a pro anno interest must be paid from January 1st to July 1st 2024.

The pro anno interest rate for the income year 2023 is set at 5.5% per year. In reality this corresponds to approx. 8% before tax for most people, as the interest is not deductible. This is a significant increase compared to 2022, when the pro annorate was 1.7% after tax.

Therefore, it might be wise to give some consideration on whether or not to pay the back tax, especially if it is not paid by 1 July 2024 at the latest.

Payment after July 1st 2024

After July 1st 2024, a residual tax is charged with a surcharge of 7.5%. For most people, this corresponds to approximately 11% before tax in a 6 month period, as the interest is not deductible. It can thus be of significant importance if the residual tax is paid on or after July 1st 2024.

Again, this is a significant increase compared to 2022, with a doubling of the surcharge from 3.7% to 7.5%.

EU agrees digital declaration system for posted workers: what it means in practice

On the 23rd of June, 2026, the European Parliament and the Council of the European Union reached a provisional agreement on a regulation establishing an EU-level digital declaration system for posted workers. The agreement is one of the first concrete outputs of the “One Europe, One Market” roadmap and is intended to reduce administrative burdens for businesses while improving enforcement of the EU Posted Workers Directive (Directive 96/71/EC, as amended by Directive 2018/957/EU).

How is property value tax calculated for a foreign property in Denmark?
The 2025 rules explained.

If you employ people who are fully tax-resident in Denmark and own property abroad, those employees are likely required to declare and pay Danish property value tax (ejendomsværdiskat) on that property. Many do not know this. Many who do know it are unsure about how to calculate it correctly.

On the 22nd of May 2026, the Danish Property Assessment Agency (Vurderingsstyrelsen) published updated indices for income year 2025. The indices are the mechanism by which the taxable value of a foreign property is determined when no Danish public valuation exists. Getting this right matters: incorrect or missing declarations can result in
reassessments, interest charges, and penalties.

This article sets out who is affected, how the calculation works, and what the deadlines are for income year 2025.
