Protesting your Property value
Notices of Valuation (NOV) for taxable real property were mailed May 1, 2025 to owners whose property had a change in valuation or change in ownership. The NOV, 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.
