The deadline to pay 2017 real estate and personal property taxes is May 10.
Interest and penalties are added if taxes are paid after that date.
Those who choose to pay their taxes by mail must have the mail postmarked on or before May 10 to be received without penalty.
Allen County Treasurer Darolyn Maley requests those who pay by mail to include their payment stubs and a phone number for employees to call if there are any problems.
