About Assessor Offices

What if I disagree with an assessment?

Most jurisdictions have an appeal process for contesting an assessment. While the specific rules vary from one locality to the next, the process typically involves a hearing before an assessment appeal board. Taxpayers who have concerns about their assessment should visit their local Assessor's Office or its website to learn about the appeal process and what information is required in order to appeal a property tax assessment.

How does my assessment affect the taxes I owe?

The formula used to calculate property taxes varies by location. Your assessment is one part of your property tax calculation. Your property tax payment is calculated by multiplying your property's assessed value, or in some cases half of the assessed value, by the tax rate for your location.

What is the difference between assessed value and market value?

Market value is the likely selling price of a property based on current market conditions. In some jurisdictions, the Assessor calculates an assessed value by applying a factor, for example 70%, to the market value. The assessed value is then used to calculate the taxes for that property.
