Summary
The act broadens the definition of 'ranch' for purposes of property taxation to mean a parcel of land that is predominantly used for grazing livestock for the primary purpose of obtaining a monetary profit. A ranch must operate through a pasture-based operation, which is newly defined as a method of livestock management where pasture-grazed livestock have regular access to open pasture and derive a majority of their diet through grazing. The act also broadens the definition of 'farm' for purposes of property taxation to mirror the predominant use language in the definition of 'ranch'. With this change, a farm means a parcel of land that is predominantly used to produce agricultural products that originate from the land's productivity for the primary purpose of obtaining a monetary profit.(Note: This summary applies to this bill as enacted.)

What changed in the latest version
34 added · 40 removedPlain-language change summary
The revised version of Senate Bill 10 includes additional details about the classification of agricultural land in Colorado, specifically addressing how this classification supports farmers with lower property taxes. It emphasizes the challenges farmers face due to rising land prices, which make it harder for new producers to enter the field, often leading to smaller-scale operations. This clarification is important as it seeks to adapt property tax definitions to reflect current agricultural practices and promote sustainable farming opportunities.
