The amount of your tax bill depends on two factors. The first is the assessed value (based on classification) of your property, which is the Tax Assessor’s job. The second is the tax rate, expressed as dollars per hundred, for each taxing entity in which property is located. This rate is set by the established budgets of taxing entities (i.e. county, municipalities, and school boards) in which the property is located. The Union County Board of Taxation then strikes the tax rate from the total amount of taxes needed to be collected.
