I've been reading up on the collection of internet sales taxes and still unclear. As I understand it I charge sales tax for items I sell in Texas because my physical presence is in Texas. Since I have nothing outside of Texas and no nexus then I don't charge sales tax for the other 49 states.
However I read that some states will start collecting sales tax no matter if you have no nexus within their state. I also read that there are thresholds that define whether or not you collect sales tax.
I assume that the merchant account will add the appropriate taxes to a sale generated on my site. I'm assuming that in a Texas sale I get those taxes which I in turn will pay to Texas but what about the state taxes collected for an out of state sale?
Clear as mud! Where can I go to get a good clarification of internet sales tax? Would a tax professional/accountant be up to speed on this?
