CO SB099

Increases the economic nexus threshold for retailers without physical presence in Colorado from $100,000 to $200,000 in annual retail sales.

Raises the threshold for small retailers with physical presence in the state from $100,000 to $200,000, allowing them to source sales to their business location regardless of where the purchaser receives the property or service.

Makes the sales tax sourcing exception permanent by repealing the sunset provision that was contingent on a geographic information system becoming available.

Applies changes to definitions of "doing business in this state" and periodic return collection requirements in Colorado Revised Statutes sections 39-26-102, 39-26-104, and 39-26-204.

Takes effect September 1, 2020, unless subject to a referendum petition filed within 90 days after final adjournment, in which case voter approval at the November 2020 general election is required.
