How Property Tax Works

Howard County, Iowa operates on a property tax system that funds essential local services including schools, county operations, libraries, and infrastructure maintenance. Property taxes are the primary revenue source for these services, with taxes collected twice annually by the county treasurer and distributed to the appropriate taxing authorities.

The effective property tax rate for Howard County varies by location within the county due to different combinations of taxing districts. For FY 2026, rates are projected to be approximately 12.25%, though this can vary depending on which school district, city, and other special taxing districts apply to your specific property. Property owners should expect rate variations based on their exact location within Howard County, as different areas may be subject to different school district levies, municipal taxes, and special assessment districts.

Supplemental Tax Bills

Supplemental taxes in Howard County are additional property tax bills issued when there are changes to property ownership, value, or classification that occur after the annual assessment date of January 1st. Common triggers include new construction completion, property transfers that reveal undervaluation, or changes in property use classification.

When supplemental taxes are issued, they are calculated based on the difference between the new assessed value and the original assessed value, multiplied by the applicable tax rate for the remaining portion of the tax year. For example, if a home addition is completed in June and increases the assessed value by $50,000, the supplemental tax would be calculated on that $50,000 increase for the remaining months of the tax year (July through December).

Escrow & Property Taxes

Most mortgage lenders in Howard County require property tax escrow accounts, where you pay 1/12th of your annual property tax bill with each monthly mortgage payment. Lenders typically collect an initial escrow deposit at closing and may require a cushion of 1-2 months of tax payments.

Property tax bills are issued in August each year, with payments due September 1st for the first half and March 1st of the following year for the second half. Your lender will receive the tax bill and make payments on your behalf from your escrow account. It's important to verify that your lender has the correct mailing address and that payments are made on time, as you remain ultimately responsible for ensuring taxes are paid even when using escrow.
