How the tax is worked out
As an illustration of the arithmetic: at Story County's derived rate of 1.47%, a home valued at $400,000 would carry a tax bill of roughly $5,888 a year. That is only an illustration using the derived rate — a real bill is computed from the property's assessed value, its exemptions, and the combined rates of its specific taxing districts, so it can be higher or lower.
The usual sequence is: the local assessor values the property; exemptions are applied; the taxable value is multiplied by the combined local rates; and the county bills and collects the tax, distributing it to the schools, municipalities and districts that levied it.

Checking your assessment in Story County
If your bill looks wrong, work through these steps:
1. Get your property record card from the assessor and check the basics — living area, lot size, bedrooms, condition, and any exemptions you should have.
2. Compare your assessed value with recent sale prices of similar homes in Story County.
3. Talk to the assessor's office informally first; clear errors are often fixed without a hearing.
4. If needed, file a formal appeal with the local review board before the deadline on your assessment notice, with your evidence attached.
5. Keep paying the bill as issued while the appeal runs, unless your notice says otherwise — unpaid taxes accrue penalties regardless of an appeal.
