In Colorado, land used as a farm or ranch for the previous two years and today qualifies as agricultural land, valued on earning capacity capitalized at 13% instead of market value. Agricultural property is assessed at 25% of actual value for 2026. Jefferson and Park county assessors accept a grazing lease, IRS Form 1040-F or brand inspection certificates as proof.

What qualifies as agricultural land in Colorado?
- Two years of use, plus today. C.R.S. 39-1-102 requires use as a farm or ranch for the previous two years and presently.
- A ranch grazes for profit. The statute defines a ranch as land used for grazing livestock for the primary purpose of obtaining a monetary profit.
- Forest land counts at 40 acres. Forest land qualifies at 40 acres or more.
- Acreage alone does not qualify. The test is use. A 35-acre parcel with no livestock or crops is not agricultural land.
The county assessor decides classification. Ask the assessor to review the parcel before you close.
How do you prove agricultural use in Jefferson and Park counties?
- Jefferson County: an agricultural affidavit. The assessor accepts IRS Form 1040-F, leases, brand inspection certificates and a livestock-watering well permit as proof.
- Park County: a questionnaire. The assessor accepts a lease agreement or lease payment receipt, a 1040-F and brand inspection certificates.
- Park County: every year. Owners must qualify each year.
- A grazing lease works. Owners who do not run livestock themselves lease the grass to a rancher and submit the lease.
How does Colorado value agricultural land?
- Earning capacity, not sales. C.R.S. 39-1-103(5) values agricultural land on its earning capacity, capitalized at 13%.
- The 2026 assessment rate is 25%. HB24B-1001 set the rate for commercial and agricultural property at 25% for 2026.
- Read the assessor record. It shows the land and the improvements as separate lines.
