What's economic nexus?
After the 2018 Wayfair decision, states can require sales tax registration once you cross thresholds — typically $100K or 200 transactions per year — even without a physical presence.
I haven't been collecting — am I in trouble?
Probably owe back tax, but voluntary disclosure agreements (VDAs) can dramatically reduce the look-back period and waive penalties.
Do you support marketplace sellers?
Yes — most marketplaces (Amazon, Etsy) collect on your behalf, but you may still have registration and reporting requirements. We handle both.
Which states tax SaaS?
About half — including New York, Texas, Pennsylvania, and Washington. We'll map your exposure.
