How Property Tax Works

Audubon County, Iowa operates under the state's property tax system to fund essential local services including schools, county government operations, emergency services, and infrastructure maintenance. Property taxes in Audubon County are assessed annually based on the assessed value of real estate, which is determined by the County Assessor at approximately 100% of market value as of January 1st each year.

The effective property tax rate in Audubon County typically ranges around Iowa's statewide average of approximately 1%, though actual rates vary significantly by location within the county due to different combinations of taxing districts. Your specific tax rate depends on which school district, city, township, and special taxing districts (such as hospital districts, library districts, or drainage districts) serve your property. Unlike some states, Iowa does not impose a statewide assessment cap, allowing local taxing authorities more flexibility in setting rates based on community needs.

Property tax bills in Audubon County fund critical services including the Exira-EHK Community School District and other local school systems, county road maintenance, law enforcement, the county courthouse operations, and various special districts that may serve your specific area. The exact combination of these services and their associated tax rates creates your property's unique total tax liability.

When Are Property Taxes Due?

For the 2025/2026 tax year in Audubon County, property taxes are due in two installments:

Pro tip: If you pay through mortgage escrow, your lender splits these payments across your monthly mortgage. If you pay directly, set calendar reminders to avoid late penalties.
Section 4

Supplemental Tax Bills

Supplemental property taxes in Audubon County are additional tax assessments that occur when there are significant changes to a property during the tax year. The most common triggers include new construction completion, major improvements or additions, changes in property ownership that reveal unreported improvements, or corrections to assessment errors discovered after the regular tax roll is finalized.

When supplemental taxes are triggered, the County Assessor calculates the difference between the property's previous assessed value and its new assessed value, then applies the current year's tax rate to this difference. The supplemental tax covers the period from when the change occurred (or should have been assessed) through the end of the current fiscal year.

For example, if you complete a $100,000 home addition in Audubon County in March and your combined tax rate is 1.2%, you could expect a supplemental tax bill of approximately $900 (75% of the year remaining × $100,000 increase × 1.2% rate). Supplemental tax bills are issued separately from your regular annual property tax bill and have their own payment due dates, typically 30 days from the issue date.

Escrow & Property Taxes

Most mortgage lenders in Audubon County require borrowers to maintain an escrow account for property tax payments, especially when the loan-to-value ratio exceeds 80%. Your lender collects monthly escrow payments as part of your mortgage payment, typically 1/12th of your annual property tax liability plus a small cushion to account for potential tax increases.

Property taxes in Audubon County are due by January 2nd of each year (or the next business day if January 2nd falls on a weekend). Lenders typically pay your property taxes in late December or early January to ensure timely payment and avoid penalties. Your lender will receive tax bills directly from the Audubon County Treasurer and should provide you with copies of payment confirmations.

If you pay your own property taxes (without escrow), you can make payments online through the Audubon County Treasurer's website, by mail, or in person at the courthouse located at 318 Leroy St, Audubon, IA 50025. Online payments may be made via credit card or e-check, though a convenience fee may apply. The county charges $2.00 per parcel for providing property tax payment information per Iowa Code Section 445.5(3). Homeowners should verify their escrow account balance annually and request adjustments if taxes increase or decrease significantly.

Frequently Asked Questions

Q: When are property taxes due in Audubon County? A: Property taxes for the current fiscal year are due by January 2nd, 2026. If January 2nd falls on a weekend or holiday, the due date extends to the next business day. Late payments are subject to penalties and interest charges.

Q: What tax credits are available and do they require application? A: Iowa offers several tax credits that require annual application, including the Homestead Tax Credit (available to all qualifying homeowners), Military Service Tax Credit, and for 2023 and forward, an additional Homestead Tax Exemption for claimants age 65 or older. These are credits that reduce your tax bill, and all require application - they are not automatic.

Q: How does the Homestead Credit work? A: Iowa's Homestead Credit is not an exemption that reduces assessed value. Instead, it's a tax credit that reduces your actual tax bill and helps limit annual assessment increases. You must apply annually, and it provides protection against dramatic year-over-year tax increases while offering a direct credit against your tax liability.

Q: When are properties reassessed in Audubon County? A: Audubon County assesses all properties annually as of January 1st. The County Assessor reviews market sales, property improvements, and other factors to determine assessed values. Property owners receive assessment notices in the spring and have specific deadlines to appeal assessments they believe are incorrect.

Q: What happens if I pay my property taxes late? A: Late property tax payments in Audubon County incur penalties and interest charges as specified by Iowa state law. Continued non-payment can eventually lead to tax lien sales. Contact the County Treasurer immediately if you cannot make timely payment to discuss possible payment arrangements.

Q: Can I pay my property taxes online? A: Yes, Audubon County offers online property tax payments through their official website. You can pay via credit card or e-check, though convenience fees may apply. There is also a $2.00 per parcel charge for accessing property tax payment information online.

Q: How do special taxing districts affect my tax bill? A: Your property tax rate includes levies from all taxing districts that serve your property, including school districts, city/township levies, hospital districts, library districts, and drainage districts. Properties in different locations within Audubon County will have different total tax rates based on which combination of these districts serve that area.

Contact the Audubon County Assessor's office at 318 Leroy St, Audubon, IA 50025 for information about appeal deadlines and procedures. Appeals typically must be filed within specific timeframes after assessment notices are mailed.

Q: Do I need to reapply for tax credits every year? A: Yes, most tax credits in Iowa, including the Homestead Credit and Military Service Credit, require annual application. The application deadline and requirements may vary, so contact the Audubon County Assessor's office to ensure you don't miss important deadlines that could affect your tax liability.
