Your Taxes at Work

There are two primary ways that you directly contribute tax dollars to Boulder County:

Property Taxes

Boulder County retains a little more than one-quarter (28%) of your total property taxes. The remainder goes to school districts (54%), cities (11%) and special districts (7%). The county uses those funds to provide essential services directly to residents, as well as indirectly to residents through funding for local nonprofit agencies.

Property tax rates within Boulder County vary according to location within municipal and special district boundaries. The Boulder County Treasurer collects all the funds and then divides them between various governmental agencies and special tax districts. These districts include local school districts, fire protection districts, municipality and/or water district among others. In all, there are 88 taxing entities that receive a portion of all collective property taxes each year in Boulder County alone.

Sales and Use Taxes

  • Sales taxes: These are taxes collected at the point of purchase when you buy retail goods within Boulder County.
  • Use taxes: These are taxes assessed on motor vehicles during vehicle registration, and also on the purchase of building and construction materials collected when a building permit is obtained.

Sales and use taxes are collected by the State of Colorado and redistributed back to the counties and municipalities where they were collected. Boulder County receives less than 1 percent* of the value of all purchases made within the county. For more information on sales and use taxes in Boulder County, download the Sales and Use Tax Brochure.

*The total sales tax rate in Boulder County varies from location to location based on varying municipal sales tax rates. The sales tax rate for Boulder County government is 0.80 percent (8 cents on a $10 purchase) and applies to all purchases made within county boundaries.
