Welcome to Adams County!

Response to COVID-19:

Governor Reynolds has issued several Proclamations of Disaster Emergency relating to the COVID-19 pandemic which affect property taxes, vehicle registration renewals and driver’s licenses as follows:

PROPERTY TAXES:  Suspension of penalties and interest for property tax payments until May 27, 2020.  Taxes are marked delinquent if not paid by March 31, 2020,  but late penalties and interest will not apply until May 28, 2020.

VEHICLE REGISTRATION RENEWALS:  Delinquent penalties on unpaid annual registration fees with a renewal month of January, February, or March will be delayed until May 28, 2020. 

DRIVER’S LICENSES: If your driver’s license has an expiration date of January 16, 2020, or later you do not have to renew your license at this time. It will remain valid for driving purposes until the declared disaster has ended.

See Treasurer’s office department page for making appointments to visit the office.

Adams County was established by the state legislature in 1851 and named in honor of the second President of the United States, John Adams, or his son, the sixth President, John Quincy Adams (sources differ). The county was finally organized and separated from Pottawattamie County on March 12, 1853. Its original size was later reduced by the creation of Montgomery and Union counties.

The first county seat was Quincy. In 1872, it was moved to Corning.
