Economic-nexus rules change and have exceptions (marketplace-facilitated sales via Amazon/Etsy often don't count toward your threshold; some states measure a calendar year vs a rolling 12 months). Always confirm with a qualified CPA or the state's Department of Revenue before registering or filing. Thresholds last verified June 2026.
