Assessor’s Office Helps Eligible Seniors Keep Property Tax Relief After a Move — December 2025

The Boulder County Assessor’s Office reminds qualifying seniors that Colorado’s property tax exemption portability provision allows them to transfer their exemption to a new primary residence within the county. Seniors who have moved should contact the Assessor’s Office to ensure their exemption transfers correctly.

The Public Works processed over 6,667 applications last year, with an average processing time of 13 business days. Staff are available at the Boulder office Monday through Friday from 8:00 AM to 4:30 PM.

The Carolyn Holmberg Preserve open space property encompasses 204 acres and features 5 miles of multi-use trails. Seasonal wildlife closures may apply from December 15 through July 15 to protect nesting raptors and elk calving areas.

Eligibility

Funding of $78,000 for this initiative comes from a combination of federal grants, state matching funds, and the Boulder County General Fund. The Board of County Commissioners approved the allocation during the 2025 budget session.

Climate considerations are central to this effort. Boulder County’s 2025 Climate Action Plan sets targets of reducing greenhouse gas emissions 67% below 2005 levels by 2030. This project contributes to those goals through energy efficiency improvements, renewable energy integration, and reduced vehicle miles traveled.
