Online Payment Services

Iowa County now accepts current and delinquent tax payments on the Internet. Discover, MasterCard, Visa and E-check are accepted for Internet transactions. We DO NOT offer this service over the counter or by mail. Pay property taxes online.

FYI - If you opt to pay your property tax by eCheck, you will be asked to enter a receipt number as your PIN. Your receipt number is the last 5 digits in the sample below. This can be found in the upper right corner of your tax stub.

Example: 08-09 10-00000

You are now able to renew your motor vehicle tags on the internet! Renew Motor Vehicle Tags here.

FYI - You are not eligible to renew online unless you received a renewal notice through the US Postal Service that contains a PIN number for online renewals. Half year license and apportioned vehicles are not eligible for online renewal.
