Notice of Valuation
Assessing Services mails a Value Notice to each property owner mid-March every year. The assessment on Jan. 2 forms the basis for the following year’s tax.
For example, a value notice sent in March 2026 will be the basis for your 2027 property taxes. See a copy of the Notice of Valuation.
The market value of property provides the basis for the amount of property taxes you pay each year. This market value is based off open market sales data over a year-long period.
Understanding your notice
Each Notice of Valuation includes:
Value is what the assessor estimates your property would likely sell for on the open market. Assessors value property at 100 percent of market value.
This is the assessor's estimate of the value of the new or previously unassessed improvements that have been made to your property within the past five years.
Only applies to agricultural property that is facing increasing value due to development pressures not related to the agricultural value of the land. The assessor arrives at this lower value by looking at what comparable agricultural land is selling for in areas where there is not development pressure. The taxes on the higher value are deferred until the property is sold or no longer qualifies for the program. See Green Acres for an expanded definition.
For land that has been recently platted (divided into individual lots) but not yet improved with a structure, the increased market value due to platting is phased in over time. If construction begins, or if the lot is sold before expiration of the phase-in period, the lot will be assessed at full market value in the next assessment.
The maximum exclusion amount has increased for assessment year 2024 and beyond. This applies to residential homesteads and to the house, garage and one acre of land agricultural homesteads. The exclusion is a maximum of $38,000 at $95,000 of market value, and then decreases by 9 percent for value more than $95,000. The exclusion phases out for property valued at $517,200 or more.
This is the value that your property taxes are actually based on, after all the reductions, limitations and deferrals. Your taxable value, along with the class rate and the budgets of your local government, will determine how much you will pay in taxes. The taxes you will pay in May will be determined from the previous year's taxable market value. Remember: Your property is assessed in one year and taxed in the next year.
