COM has legislative authority to assess and collect ad valorem taxes on the value of properties within its district. The tax rate is comprised of two elements, which become the total rate charged to the taxpayers of Galveston County:

Maintenance and Operations (M&O) -The M&O rate is set by the COM Board of Trustees to fund current operating expenses of COM based on the approved budget.

Interest and Sinking - The I&S rate is determined by the annual debt service amount on voter-approved bonds and approved by the COM Board of Trustees.

The Galveston Central Appraisal District provides the valuation for properties within the colleges' taxing district. COM offers several favorable exemptions that reduce the amount of taxes for a homeowner. Homeowners can apply for one or more exemptions with the appraisal district using the appropriate form.

The Galveston Country Tax Assessor-Collector calculates the tax bills and collects property taxes on behalf of COM.
