Last year, to attend a tradeshow I opened a sales tax account and Wisconsin. As I was engaged in extended travels afterwards, and made no sales taxable sales at the show, I did not file any returns with them. If course, they expect you to file each quarter even if to report zero sales. When I returned it to my house nine months later, I found a wide variety of letters from them culminating in lien on my bank account for about $1500. Why they decided that I would have $10,000 in sales that were taxable, given on my history of never having reported anything ever on a brand-new account, I have no idea. Strangely, others at the show who also failed to ever file did not receive liens.
