Norway’s new housing valuation model is triggering sharp tax hikes for homeowners, with pensioners facing steep drops in disposable income starting in 2026. Senterpartiet, a key budget ally of the government, demands immediate clarification from Finance Minister Jens Stoltenberg on how the system will be adjusted to avoid what critics call a “tax bomb.”
Mounting Pressure on the Finance Ministry
Bjørn Arild Gram, Senterpartiet’s finance spokesperson and deputy chair, says the issue cannot wait until the revised national budget next spring. “This case can’t drag on for months,” he told E24. “I expect the finance minister to take initiative with us budget partners to sort this out quickly.” The party finds it odd they haven’t been contacted directly by the ministry despite their role in shaping fiscal policy.
The controversy centers on a new property valuation method introduced by the Norwegian Tax Administration. Designed to better reflect market values, the model has instead assigned significantly higher assessed values to primary residences than previously estimated. That shift directly impacts wealth tax calculations beginning in 2026 and municipal property taxes in adopting cities like Oslo from 2028.
Skyrocketing Assessments, Shrinking Incomes
Homeowners across Norway have already received preliminary tax assessments showing dramatic increases—sometimes doubling or tripling their property’s listed value. Many argue these figures exceed realistic sale prices, especially in rural areas or smaller towns where housing markets are less active. For retirees living on fixed incomes, the consequences are particularly severe.
Pensioners report that their 2026 tax bills could slash monthly payments by thousands of kroner. Single pensioners, who often lack secondary earners or assets to offset the burden, are hit hardest. One retiree in Møre og Romsdal described seeing her home’s assessed value jump from 3.2 million to over 7 million kroner—despite no renovations or local price surges.
The wealth tax rate itself has also risen—from 0.85% in 2021 to 1% today, with a second tier of 1.1% applying to net wealth above 21.5 million kroner. Combined with inflated valuations, even middle-class homeowners now face unexpected liabilities.
Budget Forecasts Derailed by Data
When presenting the 2026 state budget last autumn, the Ministry of Finance projected an additional 435 million kroner in wealth tax revenue due to the new model. But recent figures from Statistics Norway (SSB) suggest the actual increase could be more than double that amount.
That discrepancy has alarmed coalition partners. If SSB’s updated estimates hold, the state stands to collect over half a billion kroner more than anticipated—not through policy changes, but through technical adjustments in valuation methodology. Senterpartiet argues this outcome contradicts the government’s stated goal of revenue neutrality.
Finance Minister Jens Stoltenberg has acknowledged the model needs revision and insists any changes will be “revenue-neutral.” However, he has not specified how that balance will be achieved or whether affected taxpayers will receive retroactive relief. His department plans to unveil adjustments alongside the revised national budget in spring 2026—a timeline Senterpartiet calls unacceptably slow.
Oslo and Other Municipalities Brace for Impact
While wealth tax is a national levy, the model also affects municipal property tax in communities that choose to adopt it. Oslo, which uses the national valuation framework, will see higher property tax bills starting in 2028. Local officials worry about public backlash, especially among elderly residents in neighborhoods like Grünerløkka or Nordstrand, where modest apartments have seen outsized revaluations.
Other municipalities are watching closely. Some may delay adoption if the national model remains unstable. The uncertainty complicates long-term planning for local budgets that rely on predictable property tax streams to fund schools, elderly care, and infrastructure.
Critics note that the current system fails to account for regional disparities. A cabin in Finnmark or a farmhouse in Hedmark might be valued using algorithms calibrated for urban markets like Bærum or Bergen, leading to distorted outcomes. The Tax Administration maintains its model uses verified sales data, but homeowners say recent transactions in their areas don’t support the new figures.
A Test for Norway’s Coalition Government
The housing tax dispute tests the cohesion of Norway’s governing coalition, which includes Labour (Ap), the Centre Party (Sp), and the Socialist Left (SV). Senterpartiet, representing rural and agricultural interests, has long championed tax fairness for non-urban residents. Its frustration signals deeper tensions over fiscal priorities.
Gram’s demand for urgent talks reflects growing anxiety within the party’s base. With local elections approaching in 2027, prolonged inaction could fuel voter discontent, particularly in districts where retirees form a significant share of the electorate. The issue also intersects with broader debates about housing affordability and intergenerational equity.
Stoltenberg’s office has not confirmed whether emergency consultations will occur before the spring budget update. Meanwhile, citizens await clarity on whether their homes—often their largest asset—will trigger unaffordable tax burdens through no fault of their own.
As winter approaches and preliminary tax notices circulate, many Norwegians are left wondering: Will the government act swiftly to defuse this tax bomb, or let it explode in 2026?
