Why do we have a property tax?

  • Property taxes provide public benefits such as schools, fire, and police protection.
  • Properties are appraised at fair market value as established by willing buyers and sellers. Each property owner pays their fair share of the tax burden in proportion to the amount of value their individual properties are worth.
  • When the community spends tax dollars on schools, parks, and other community interests, this can enhance property values.
