Understanding Property Tax Appeals

How the Appeal Process Works

The property tax appeal process typically begins with a review of your property's assessment, which is the value assigned to your property by the local tax authority. If you believe your assessment is incorrect, you can file an appeal with the county tax board or equivalent local authority. The appeal will be reviewed, and a decision will be made based on the evidence presented.
