And if I have to start filing tax returns with every state and county my small business happens to do business with (~$1000 / year business), I'll probably shut that down entirely for not being worth the bother as well.
Almost sounds inspired by crazy European Union VAT laws! American companies are technically required to register to collect EU VAT if their sales to any EU territory are over a certain amount. Thankfully, most smaller ones don't.
The level above which you have to register to collect the VAT is there precisely to protect the smaller companies which make a few small sales to the EU. If you are making enough sales to be over the threshold you should be able to afford to abide by the law.
Except it's a bizarre law because those US companies are not necessarily in the EU themselves. It'd be like California demanding a business in Poland should charge local California sales taxes for any exports to that state.
