Property tax information – Assessor
Garfield County moved to a new web address in March. Find us then at garfieldcountyco.gov. Domains like this are more trusted, because only official governments can use them.

ATTENTION: The assessor's office is closed on Monday, January 26, from 9 – 11 a.m. for staff to attend our annual service awards celebration.

Property tax information

Beginning in 2025, residential property has two assessment rates. One assessment rate will be used to calculate local government assessed values and the other rate will calculate school district assessed values.
Beginning in 2026, the residential actual value for local government purposes will be adjusted by 10% of the actual value of the property not to exceed $70,000 and not to reduce the assessed valuation below $1,000.

  • Actual value x assessment rate = assessed value
  • Assessed value x mill levy/1000 = tax bill

2026 Assessment rates*

  • Residential – School 7.05% Local Governments 6.8%
  • Commercial and Agricultural (Real & Personal) – 25%
