The general rule in the US, as far as I can determine is that if you have a business presence in a state, you have to pay tax there. This applies if you own your own servers in the sate, or if you have employees.

Thus it might be beneficial for me, living in Europe to only rent servers, and to avoid hiring someone from the US as a full-time employee.

The New Law Amazon Is Fighting Affects All Affiliates

The chances are if you have an affiliate program, that at least one of your affiliates is based in the New York area.

Whilst it is possible to limit an affiliate program to only affiliates from outside New York, it would be extremely hard to police.

An affiliate themselves could have employees in NY, or run servers there.
