Tax Levy Calculation

How Taxes Are Calculated

Based on the budgets submitted by the various levying authorities, the Auditor's Office prepares and certifies the levy rates in the county. Budgets for each levying authority are based on its taxable valuation as well as levy limits established by the Code of Iowa. Levy rates are expressed in dollars and cents per $1,000 of taxable valuation.

Property taxes due during a fiscal year are based on the assessed property value as of January 1 of the preceding year, i.e. the assessments for January 1, 2024 (mailed in April of 2024) will be the basis for the taxes paid in September of 2025 and March 2026. For a detailed primer of local property tax, see the Iowa Legislative Services Agency Local Property Tax guide.
