Partial & Scheduled Payments

Monona 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 31) 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. 

Drainage and Special assessments are not types of taxes that can be collected with partial/scheduled payments.
