200,000 homeowners to receive corrected tax assessments after error

Around 200,000 Danish homeowners will receive revised preliminary tax assessments after an error omitted property tax charges, public broadcaster DR reports.

The mistake, caused by a supplier failure at the Tax Administration, left the land tax (grundskyld) missing from the 2026 preliminary assessments sent to affected property owners on 1 May. The property value tax (ejendomsværdiskat) was correctly stated.

According to the Valuation Agency (Vurderingsstyrelsen), corrected assessments will be automatically resent within days, with no action required from homeowners. The error does not affect the April or May payroll runs.

“I regret this supplier error, but we’ve caught it quickly and are correcting it,” said Anne-Sofie Jensen, director of the Valuation Agency. “The affected homeowners will receive a new assessment automatically—no steps are needed on their part. We apologise for the mistake.”

The agency confirmed that the planned use of final 2024 property valuations for both taxes remains unchanged, despite the temporary omission of land tax data.

Denmark’s property valuation system has faced long-standing challenges. A 2015 report by the National Audit Office (Rigsrevisionen) found that three-quarters of valuations in 2010–2011 were incorrect. A new IT system, launched in 2021 after repeated delays and cost overruns—now estimated at nearly DKK 5 billion—was intended to resolve these issues.
