A trivial computing problem.
It is indeed, despite Slobodan's metaphorical like FUD that is literally wrong in calculating sales tax. To fill out state sales tax, one needs simple addition and division. At least in those two small sates I've done it in (California and New Mexico). One can do this on a computer, a calculator or on paper. Well
some might be able to do this on paper if they have the concepts of basic math and can pull themselves away from telling us how SCOTUS and the Gov will ruin everything. In terms of taking 5 minutes to file sales tax, I've ben doing it over 30 years, and it takes ME five minutes. No, I do not need an accountant to do this, maybe some here do. Filing state
sales tax reports isn't the same as filing federal income taxes despite a retired poster here suggesting it is necessary to involve an accountant. Maybe for him, not for me, perhaps not for others. The FUD-mongers are predicting nightmares and massive problems but until then, it's more of the political FUD we see in this forum. Some are more concerned and find more nightmares in filling sales sales tax than they do in our climate changing as indicated again in this forum. And as we see in this forum, everything has to be reduced to how awful government is, with a political slant to blast out the FUD.
Let's see what happens before all the doom and gloom because unless you've experienced, you're only imagining it! If you've experienced it, tell us actual experiences, not metaphorical FUD about what might. What the ruling does is level a playing field and will generate more funds for the states. I see that as a good thing THUS FAR. You old white guys can complain, predict, spew FUD and maybe some of that will result; come back when it does and tell me so. Until then, I can't understand the obsession with a utter lack of following the spirit of THIS web site; photography! Maybe because some here are less photographers than professional FUD-mongers.
