If you are a merchant in the process of choosing an affiliate network - ask the network sales person about the reports available to help with compliance with NY, Rhode Island, North Carolina, and Illinois "Amazon Tax" laws.

I am noticing a distressing lack of tools and interest in providing them in the "Big 3 Networks." Since this issue is going to increase in scope before it gets resolved through the courts or through federal intervention, you might want to make sure that you have easy access to reports on sales by affiliates by state and the ability to pull transaction detail reports to compare to your internal sales database to determine if the sales qualify under the laws that are being passed.
