Checks which US states a remote seller must register in to collect sales tax (economic nexus). Send sales and order counts per state for the last 12 months or a calendar year, and whether they include marketplace sales (Amazon, Etsy). Returns states over the threshold (must register), close to it (80 percent or more) and under it, with each state's threshold, measurement period, what counts and the revenue department source. Information, not tax advice.
