Just for a warning to all who DON’T think they have to charge sales tax. I use FBA and have only been charging sales tax for my own local state of NJ. The state of MA sued Amazon for the information of sellers who shipped and stored product in an Amazon warehouse located in the state of MA. MA won the case and Amazon was forced to give over the information of all sellers who stored inventory in the MA Amazon warehouse.
MA is now going after all sellers who stored inventory in their state and saying that not only do they have to collect sales tax moving forward but that they owe back taxes to the state for any MA transaction since the first product that seller stored in the warehouse beginning in October of 2016. (because that is the date that the MA Amazon warehouse opened). So if you sent one product to the MA warehouse in October of 2016, you are considered to have Nexus in MA and you would owe any sales tax for MA transactions since the first date your product that arrived in MA.
I received a letter in the mail from MA about this a month or so ago and I now owe a hefty chunk of change via back taxes and there is nothing I can do about it. (Could I just simply ignore the letter, Yes. But MA said they would just add additional fines and interest on top of what I owe and get a court order to force me to pay the back taxes and fees)
I am now collecting in all states that I have a significant amount of sales in so as to not run into this back tax problem that I am dealing with for MA. I would suggest any seller AT MINIMUM, look at their sales history for the past year or so and see what states they do the most business in. I myself decided that if these certain states where to come after me, just like how MA did, I would be in serious financial trouble as collecting for all 50 states is just absurd so I now collect for 6 states total.
