Home Improvement Exemption (H.I.E.)

The H.I.E. is available to homeowners who have made a physical improvement to their property. I.e. added a deck or sunroom, finished a basement, put on an addition to the home, etc. This tax break exempts up to $75,000 in Market Value or (25,000 Assessed Value) in improvements made to a property. The improvements will not be added to your Assessed Value for 4 years from the date of completion.

Our office automatically applies this exemption after the inspection by the one of the Township Deputies.
