Best alternatives to Nexus Snapshot in 2026
If you sell online across the US, there's a good chance you've triggered a sales tax obligation in a state you've never even thought about — most states set an 'economic nexus' threshold (a dollar amount or transaction count) that, once crossed, means you're legally required to register and collect tax there, even without a physical presence. Nexus Snapshot checks your numbers against all 50 states' thresholds and points out exactly where you may already be on the hook. The quick check is free: enter either your total US sales or state-by-state figures and get results in seconds, no account required. For a fuller picture, a $29 report adds state-by-state detail, documentation, and instant email delivery via a secure Stripe checkout. Threshold data is updated quarterly, which matters because states periodically revise their limits.
