What's wrong may be that the State of New York says that, if you are doing business in the State, which 5678 is, then you must collect State retail sales tax.
You might find that out after a couple of years and owe megabucks to them.
There's a whole fooferall going on in the States right now about this - California has even gone so far as to say that, if you have affiliates in California, then you are deemed to be doing business there.
The River cut off all their affiliates in several states because of this.
