Hi Michele,
I recently became certified with the state of NJ, that is a requirement to be a third party biller and be able to bill for a doctor in that state.
I live in PA but I am tri-state Like 20 minutes from Port Jervis NY and 15 min. From Montaque NJ.
When I became certified they sent me a letter saying I have to register with the NJ Dept. of Treasury to do business in NJ, but I think they are missing the fact that I am a service based buiness and no sales tax will be charged.
I know you said you bill for different states, I was wondering do you have to register with the dept. of Treasury in all the states you bill for? I am confused!
