In-State Businesses

Doing Business In Colorado

A retailer is doing business in Colorado and subject to all sales tax licensing and collection requirements if the retailer maintains any place of business in Colorado directly, indirectly, or by a subsidiary. Such a place of business may include an office, distribution facility, salesroom, warehouse, storage place, or home office of a Colorado resident employee. For more information on how to collect and remit sales tax, visit the Sales & Use Tax web page.

Destination Sourcing Deadline Extended

Governor Polis signed SB21-282 on June 30, 2021, which extends the small business exception to destination sourcing requirements. This exception applies only to businesses with less than $100,000 in retail sales. Beginning February 1, 2022, all retailers will be required to apply the destination sourcing rules.

General Destination Sourcing Rules

Sales tax is now calculated based on the buyer's address when the taxable product or service is delivered to the consumer. This is called destination sourcing. Destination sourcing is also used when a product or service has a lease/rental agreement with periodic recurring payments.

Businesses will now be required to collect and remit sales tax for all retail sales to Colorado consumers, regardless of the physical location for the business. In general, a retail sale is made at the location to which it is sourced in accordance with the following rules:

  1. If the purchaser takes possession of the purchased property or first uses the purchased service at the seller's business location, the sale is sourced to that business location.
  2. If the property or service is delivered to the purchaser at a location other than seller's business location, the sale is sourced to the location the purchaser receives the purchased property or first uses the purchased service.
  3. If the purchaser requests delivery of the property or service to another recipient (i.e. the purchase is a gift), the sale is sourced to the location the recipient takes possession of the purchased property or first uses the purchased service.

If a sale cannot be sourced using the preceding rules, section 39-26-104(3)(a), C.R.S., provides additional guidelines for sourcing retail sales based upon the seller's records, the purchaser's payment instrument, or the location from which the property was shipped. These sourcing rules do not apply to leased property. See Department publication Sales & Use Tax Topics: Leases for sourcing rules for lease payments.
