Sales Tax Licensing

Collection & Administration

Other than liquor licenses, Adams County does not have a separate sales tax license. Since all collection and administration of the sales tax is the responsibility of the Colorado Department of Revenue, having a state sales tax license is sufficient for operating a business within Adams County.
