Collection of Property Taxes

It is the Treasurer’s duty to collect all taxes, certified by the County Auditor, which includes real estate, mobile homes, special assessments, buildings on leased land, equipment assessed as real estate, utilities and grain handlers.

The County Auditor delivers tax lists of the various districts to the Treasurer at the beginning of each fiscal year.

Taxes are segregated in taxing districts, and the amounts collected are apportioned to the various funds; State, Area Schools, Ag Extension, Assessor/Appraiser, County, School, corporate entities and townships.

Property Tax Payments

  • Property taxes may be paid in two installments. 
  • The first half is due September 1 and becomes delinquent October 1; the second half is due March 1 and becomes delinquent April 1.
  • Delinquent interest accrues at the rate of 1.5% per month, rounded to the nearest dollar with a minimum of a dollar.
  • Payments for redemption from tax sale must be paid by guaranteed funds.
  • The rate of interest required by Iowa law to be paid in a redemption is 2% per month.

Notice of Delinquent Taxes

The law requires that a notice be sent to property owners who have outstanding taxes as of February 1.

The notification explains that under Iowa law, it is important for property owners to pay taxes and special assessments when they are due in order to avoid the tax sale.

Iowa law also requires that a notice of the annual tax sale shall be mailed not later than May 1 to the person in whose name the parcel subject to sale is taxed.

In compliance with this law, a Delinquent Tax Statement and Tax Sale Notice is mailed in April to provide proper notice of the pending tax sale.

Delinquent taxes as of May 1 are assessed a publication fee and must be advertised for sale at the annual tax sale in June. 

Tax Sale

The Annual Tax Sale is held the third Monday in June at 8:30 a.m. with an adjourned sale scheduled for the third Monday of each subsequent month.

Any delinquency must be offered for sale at the Regular or Public Bidder Tax Sale. Delinquent tax and/or special assessments advertised twice and remaining unsold for want of bidders, must be offered for sale at the annual Public Bidder Sale. Clinton County is required by Iowa law to purchase the delinquencies if there is no private sector bidder. Further, once a Certificate of Purchase at Tax Sale has been issued to the County, the Treasurer has the authority to bring an ordinary suit at law for the collection of taxes.

Exemption/Credit Applications

Exemption/Credit Applications: Iowa law provides for a number of credits and exemptions. It is the property owner's responsibility to apply for these as provided by law. It is also the property owner's responsibility to report to the Assessor when they are no longer eligible for any credit/exemption they have applied for.
