Real estate taxes support schools, fire and police protection, and other public services and benefits afforded to County residents. You help absorb these costs in proportion to the amount of money your property is worth.

The assessor’s office does not determine the total amount of taxes collected in your community, the tax rate, or your taxes. The assessor’s primary responsibility is to find the fair market value of your property. Assessments are determined prior to the County’s budget and tax rate approval.

How Taxes Are Calculated

Each year, the Department of Real Estate Assessments determines the value of real property in Arlington County. The assessment is then multiplied by the real estate tax rate, which is set by the County Board each year. Assessments begin Jan. 1. County Appraisers do not determine your property taxes; their job is simply to ensure that your assessment is fair and equitable.

All properties in Arlington County, except those designated for operating railroads, interstate pipelines or public utilities, are assessed.
