Checks which US states a remote seller (no office, staff or stock in the state) must register in to collect sales tax, from its sales into each state. Give sales_by_state with the dollar sales and number of transactions (orders) per state, the period those figures cover, and whether they include sales made through marketplaces such as Amazon or Etsy. Returns states where the seller is over the economic nexus threshold (must register), states close to it (80 percent or more), states under it, and for each the threshold, the measurement period the state uses, what sales count (gross, retail or taxable only), whether marketplace sales count, when registration must happen, and the state revenue department source. Unclear cases give the SAFE answer (treated as over) with what it depends on. Free.
