Facing Tax Foreclosure in Cass County, Iowa? Here's What You Need to Know
Homeowners in Cass County, Iowa, often don't realize how Iowa's tax process differs from other states.
If your property in Cass County has been sold -- or is at risk of being sold -- at a tax sale, this guide covers your rights and what to do next.
How Tax Sales Work in Cass County
Iowa uses a tax lien system where the county treasurer sells certificates to investors rather than auctioning property. This typically does not generate surplus funds. However, mortgage foreclosure may produce surplus under Iowa Code Section 654.7.
In Cass County, the County Treasurer handles the tax sale process. The county seat is Atlantic, where you will find the relevant offices. This county uses a tax lien process.
Your Right to Surplus Funds
If your property sold for more than what was owed in back taxes and fees, you may be entitled to the difference -- called surplus funds or "overages."
The U.S. Supreme Court confirmed this in Tyler v. Hennepin County (2023), ruling unanimously that governments cannot keep surplus from tax sales beyond what is owed. This violates the Fifth Amendment's Takings Clause. In Cass County, surplus funds are held by County Treasurer.
