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.

2026 Budget

Developing Boulder County’s annual budget is a process that starts in May each year and involves hundreds of hours of work from county staff, elected officials, and the community.

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 Dec. 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.
