For Immediate release:

Effective immediately, the Supervisor of Assessments Office in Peoria County will not require individuals already receiving specified homestead exemptions to renew their applications for 2020. The office will automatically install these exemptions for individuals who received them in 2019.

This is a proactive approach to help protect the most vulnerable members of Peoria County from COVID-19 (Corona Virus) by limiting their need to travel to the courthouse or other locations to have these forms filled out. Any new filings will still be accepted as usual, however mailing or email is preferable. The following exemptions will not require renewal for 2020:

PTAX 340-Senior Freeze Exemption

• PTAX 342R-Renewal for Veterans with Disabilities

• PTAX 343R-Renewal for people with Disabilities

If you have any questions you can go to our website at the following link to identify the forms you will not have to renew for 2020. As always you can call our office at 672-6910, or email me directly at
