Protesting your Property value

Notices of Valuation (NOV) for taxable real property were mailed May 1, 2025. The NOV, which is also available online, describes the property you own and lists the actual value for the previous year and the current year. It is your right to appeal your property valuation and/or its classification.

Property owners are encouraged to submit their property protest. The deadline for all property owners to appeal their valuations is June 9, 2025. Late protests will not be accepted. This includes supplemental information to an existing protest.
