County Budget

Annual Budget

Boulder County government fulfills many roles and carries out multiple core functions 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. We maintain our well-traveled roads, uphold the law and provide public safety services, provide housing counseling and nutrition assistance for our youngest and oldest residents, and more. Together, we also work to create visionary open space and land use policies.

Budget Development

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

The 2027 Budget process is underway. Share written feedback on the 2027 Budget with the Boulder County Commissioners.

2027 Budget Information

Every year, Boulder County develops a budget that balances the services our community relies on with the revenues available to provide those services. This year, the Office of Financial Management is asking departments to identify approximately $13.2 million in ongoing budget reductions as part of the FY2027 budget process.

The county continues to face structural budget challenges. Simply put, the cost of providing services, including personnel, inflation, and operating expenses is growing faster than our ongoing revenues.

This is about sustainability, not a financial crisis. While Boulder County remains financially stable today, the county must make proactive decisions now to ensure it remains financially sustainable in the future. Taking action early allows the county to make thoughtful, strategic decisions rather than reacting to future financial pressures.

Boulder County remains in a strong financial position. However, good financial stewardship means addressing long-term trends before they become larger problems.

By making gradual, ongoing adjustments today, we can:

  • Preserve essential public services.
  • Maintain financial stability.
  • Protect the County’s long-term fiscal health.
  • Continue investing in the priorities that matter most to our community.

This year’s budget process is guided by Priority-Based Budgeting (PBB). Rather than applying across-the-board cuts, departments are evaluating:

  • Which services provide the greatest value.
  • Which programs are legally required.
  • Which services align with Board priorities.
  • Opportunities to improve efficiency before reducing services.

The goal is to make decisions strategically, not simply reduce budgets equally across all departments.

The FY2027 budget process is about positioning Boulder County for long-term success. By making strategic decisions today, the county can continue delivering excellent public services while ensuring the county remains financially strong for years to come.

Why are we making reductions?

  • Costs are growing faster than ongoing revenues.
  • We are addressing long-term financial sustainability.
  • Acting now avoids larger reductions later.

How are decisions being made?

  • Priority-Based Budgeting
  • Data-driven analysis
  • Focus on efficiency before service reductions

Our Goal

  • Preserve essential services.
  • Protect taxpayers.
  • Invest in Boulder County’s future.

Mill Levy and Property Tax

The 2026 Mill Levies were formally approved during the Budget Adoption public meeting of the Board of County Commissioners on Dec. 9, 2025: view the meeting section concerning the Resolution Levying Property Taxes.. Boulder County will levy 24.046 mills for fiscal year 2026, with a temporary mill levy credit of -0.932. 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 2026 Budget Summary.

The Boulder County Treasurer’s Office calculates property tax using the mill levies from all taxing entities. Property tax notices are mailed out in late January each year. Find out more about how tax is calculated.
