How Property Tax Works

Property taxes are the primary revenue source for these local governmental entities, with the tax burden distributed among all property owners based on assessed values and applicable tax rates.

Property tax rates in Worth County vary significantly depending on your specific location within the county due to overlapping taxing jurisdictions such as school districts, cities, townships, and special service districts.

Supplemental Tax Bills

Supplemental taxes in Worth County are additional tax assessments that occur when property undergoes changes after the January 1st assessment date. The Iowa assessment system establishes property values as of January 1st each year, but certain events can trigger mid-year adjustments that result in supplemental tax bills.

Common triggers for supplemental taxes include new construction completion, property improvements, ownership changes that remove previous exemptions or credits, or corrections to assessment errors. When supplemental taxes are levied, they are calculated by applying the current year's tax rate to the change in assessed value, prorated for the remaining months in the tax year. For example, if a $50,000 home addition is completed in July, you would owe taxes on that additional value for the remaining 9 months of the tax year at your area's applicable tax rate.

Escrow & Property Taxes

Most mortgage lenders in Worth County require property tax escrow accounts for borrowers with less than 20% equity. Your lender collects monthly payments equal to 1/12th of your estimated annual property tax bill and holds these funds in an escrow account. The lender pays your property taxes directly to Worth County when they become due in September and March.

Lenders must provide annual escrow analyses showing the previous year's activity and any adjustments needed for the coming year. Due to Worth County's recent tax rate increases, many property owners may see escrow payment increases in 2025. If your taxes increase significantly, your lender may require you to make up any escrow shortage over 12 months in addition to the higher monthly payment. You have the right to request escrow account information and can verify payments through the Worth County Treasurer's office to ensure accuracy.
