As much as we all hate taxes, I have never seen so many people whine over a sales tax. The battle is to be won by eliminating income tax and pay higher sales tax.
My business includes live online classes. I have students all around the US. Am I supposed to now collect taxes on their signup? And am I supposed to look up each person and see if services (my classes) are subject to taxes, which state, county, and city tax applies, are their other reporting requirements, etc.?
And who is going to pay for the accountant and lawyer, the time to figure it out, collect it, file the reports. And will states then all require me to register as a foreign corporation in order to make those filings?!
This is really complicated. It is a potential no-win situation for small businesses and really for any but the biggest like Amazon.
Further, what is the effective date?! Is it from today forward or from some past date within the statute of limitations. And taxes have different one. Many of my students are in states that tax services. Do I now need to audit and for how far back? I never collected taxes, definitely can't afford to pay what wasn't collected, and the chance of me getting people from potentially years ago to cough up unpaid taxes is ridiculous.
Whine? That is too simplistic a dismissal and not fair conclusion.
