Delinquent interest accrues at the rate of 1.5% per month, rounded to the nearest dollar with a minimum penalty due of one dollar.

Partial & Scheduled Payments

Clinton County allows partial payments of currents property taxes. By law, you cannot make a partial payment on a tax sale or special assessment. If, at any time, you want to pay towards your property taxes, we will accept any amount of partial payment. 

You can make partial payments directly to our office. Or, if you prefer, you are able to schedule automatic payments from your bank account either by e-check or card. The scheduled payments will be handled through the Iowa Treasurer's website by creating an account and setting up the schedule. To do this, you will need to follow these steps:

  1. Add the property or properties you want to pay on the automatic schedule,
  2. Set up payment account or enter your banking information, 
  3. Set up schedule. You can set up the schedule to pay monthly, weekly, bi-weekly or on a set date. 

Here, you can also click "auto amount" or choose to pay a set amount each month. 

By selecting the auto amount, the system automatically calculates the number of payments you've selected and the amount needed by the due date (September 30 and/or March 30) and then will automatically pull that amount. 

If you choose to pay a set dollar amount each month, you need to be aware that the amount chosen may not cover the full amount of property taxes by the due date.  If this happens, you could incur late fees and/or additional interest. 

Notice of Delinquent Taxes

The law requires:

  • A notice be sent to property owners who have outstanding taxes as of November 1 and May 1.
  • 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
  • Payments for redemption from tax sales must be paid by guaranteed funds. The rate of interest required by Iowa law to be paid on a redemption is 2% per month.

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