About 2,200 CAUV renewal forms were mailed to residents in January.
More than 500 have yet to be returned.
Those who return the forms and qualify for the CAUV program can receive tax savings on their real estate bills.
Anyone with questions should call the auditor’s office at 419-668-8464.
“We really encourage people to take advantage of the program,” auditor Roland Tkach said. “To continue to stay on the program, residents need to mail in or drop off their forms to the auditor’s office.
“We understand the renewal form this year is more lengthy,” Tkach added. “I want to stress we are here to help you. Stop into the office or give us a call and we can help you complete your forms. We are here to serve. I can’t stress that enough.”
The auditor’s office is located at 12 E. Main St., Suite 300, in Norwalk.
