Colorado Governor John Hickenlooper has signed legislation which creates a rebuttable presumption that an out-of-state retailer has substantial nexus, effective July 1, 2014. The legislation outlines the types of business activities that create taxable sales for not only a controlled group of corporations but also for unrelated persons who perform activities on behalf of an out of state seller.
The following activities apply regardless of whether the person who has physical presence in Colorado is part of a controlled group or not.

The presumption does not apply to certain agreements or arrangements concerning advertising, affiliate marketing, and small businesses. The small business exception applies if the cumulative gross receipts from sales by the person outside of Colorado to instate customers in the prior calendar year is less than $50,000.

The presumption may also be rebutted by proof that the component member with physical presence, during the calendar year in question, did not engage in any activities in Colorado that are sufficient under U.S. Constitutional standards to establish nexus. (H.B. 1269, Laws 2014, effective July 1, 2014)
UPDATE: Colorado has repealed its click-through and affiliate nexus legislation, effective June 1, 2019.
