Steps
Pull all customer orders from your order management system grouped by ship-to state for the trailing 12-month rolling window
Aggregate both total revenue and transaction count per state, as most states use a $100,000 revenue or 200 transaction threshold (verify each state's current threshold independently)
Compare each state's aggregates against its published economic nexus thresholds and flag any state within 80% of either threshold as a warning
For states that are flagged, initiate a sales-tax registration workflow: obtain a state sales tax permit before the next taxable transaction
Re-run this analysis monthly and log the results with timestamps to demonstrate ongoing compliance monitoring
Known gotchas
Threshold rules vary by state: some states count gross sales, others net of returns; some exclude sales for resale; always consult the specific state's Department of Revenue guidance rather than assuming the common $100k/200-transaction rule
Some states (e.g., Missouri) phased in economic nexus at different dates; historical sales before the effective date of a state's law may not count toward the threshold
Marketplace facilitators such as Amazon collect and remit tax on your behalf in most states, and those sales may or may not count toward your own nexus threshold depending on state law
