County Budget


Annual Budget

Boulder County government assumes a variety of roles and carries out core responsibilities in order to help foster a vibrant, healthy, and active community.

Our annual budget process allows for the careful allocation of tax dollars to help with important county functions such as maintaining our well-traveled roads, conducting law and public safety services, providing housing counseling and nutrition assistance for our youngest and oldest residents, and working together to create visionary open space and land use policies.


2025 Budget Process

The 2025 budget has been developed with a focus on the commissioners’ three strategic priorities:

  • Economic Security and Social Stability
  • Climate Action and Environmental Stewardship
  • Good Governance

The final Budget was adopted on December 11, 2024. View the 2025 Budget Adoption meeting.

Mill Levy and Property Tax

The 2025 Mill Levies were formally approved during the Budget Adoption public meeting of the Board of County Commissioners on December 11, 2024: view the meeting section concerning the Resolution Levying Property Taxes.. Boulder County will levy 22.661 mills for fiscal year 2025, with a temporary mill levy credit of -2.133. This reflects a 5.5% growth limitation in the entirety of the county’s General Use fund, and most of the county voter-approved property tax funds.

More information about Property Tax is available in the 2025 Budget Summary section about Property Taxes.
