I’ve been warning you that states are desperate for cash. And, they got the go ahead from the Supreme Court to tax sales from out-of-state vendors. Some states want to collect tax from the first sale, others have more reasonable thresholds ($ 100K, 200 transactions). Which means we have to be vigilant about tracking our sales; more importantly, if we think we may come close to the threshold during a given year, then we better start collecting those taxes now- or be out the cash we have to shell out later.
