Changing the taxable value of a plot of land

• valuation from a qualified valuer,
• valuation by an estate agent who is familiar with the district,
• observable market value - the price for which the property/plot or a very similar property/plot in the same area has been sold. Documentation of observable market value could be a purchase agreement or similar document stating the sale price.

• By amending your tax deduction card: If you believe that the estimated taxable value is incorrect and that the error will affect the tax deduction for the 2024 income year, you can amend and order a new tax deduction card. Enter the taxable value you believe to be correct. The taxable value of a plot of land must not amount to more than 80 percent of the property's market value. You must be able to document the market value if the Norwegian Tax Administration asks you to do so. Note that the amended taxable value will not be transferred and pre-completed in your tax return. You must also change the taxable value in your tax return yourself.
  
  
• By amending your tax return: You can change the taxable value when you submit your tax return. You can change your tax return if you believe that the taxable value exceeds 80 percent of the verifiable market value. In the case of plots of land, claims for a new taxable value must amount to 80 percent of the documented market value. You must be able to document the market value if the Norwegian Tax Administration asks you to do so. You can also change your tax return if the taxable value is significantly above that of comparable properties elsewhere in the municipality.
  
  
• Changes after you've submitted your tax return or received a tax settlement notice: If you wish to change the taxable value after you've submitted your tax return or received your tax settlement notice, you're entitled to make changes yourself and submitting it.
  For the income year 2021 and 2022 you cn submitt a correction.
  Your can send for up to three years after the deadline for submitting your tax return (normally 30 April) for the income year you wish to change. However, you cannot make changes yourself if you've been notified by the tax authorities of an audit of the taxable value information or you've been informed that the tax authorities have assessed the taxable value. In such cases, the taxable value can only be changed by submitting an appeal to the tax authorities.

As the tax valuation of plots of land is based on the taxable value in the previous year, the reduced taxable value will also be used as a basis for the subsequent years, adjusted by annual adjustments where appropriate. 

The taxable value should not be adjusted upwards for the 2023 income years. The taxable value stated in the 2022 tax assessment notice will be used as a basis for the 2023 income year.
