New Mexico is following Illinois and Mississippi in 2011 by introducing an Amazon.com nexus or "click-through" nexus bill (SB 95). 

The language in the bill is:

A person with a business with no physical presence in New Mexico is presumed to be engaging in business in New Mexico and has nexus with the state for purposes of due process and interstate commerce if:

1. that person enters into an agreement with an affiliate physically present in New Mexico, for a commission or other consideration, to directly or indirectly refer potential customers, whether by link or an Internet web site or otherwise, to that person; and
2. the cumulative gross receipts from sales by that person to customers physically present in New Mexico who are referred to that person by all affiliates with an agreement described in this subsection are in excess of ten thousand dollars ($10,000) during the preceding twelve-month period ending on June 30 of any year.

The presumption of nexus established by SB 95 may be rebutted by proof that the affiliate made no solicitation in the state that would satisfy the nexus requirements of the United States constitution on behalf of the person presumed to be engaging in business in New Mexico.

For all of the details, please check out the bill, SB 95.

Just like Illinois and Mississippi, we will have to wait and see if it gets enacted.
