Municipalities Information

Most municipalities in Larimer County have a sales tax. See the County and Municipality Sales Tax Table for current sales tax rates and contacts.

Larimer County has both "Statutory" or "State Collected" as well as "Home Rule" municipalities located within its boundaries.

A "Statutory" or "State Collected" municipality, such as Larimer County, must follow the State's taxing rules and regulations, and the sales tax is collected by the State.

A "Home Rule" municipality may create its own taxing structure and be self-collected. As a result, the licensing and tax structure is different from that of the State. When operating within a "Home Rule" municipality, the vendor should contact that Town or City with questions regarding its requirements.
