About US Sales Tax Nexus, Registration & Filing
A clear overview, in simple terms — what it is, why it matters, and how we handle it.
Since the Supreme Court's Wayfair decision, a seller can owe sales tax in a US state without a physical presence once sales into that state cross its economic nexus threshold — commonly $100,000 a year, and higher in some states such as California, Texas and New York. Marketplaces like Amazon collect tax on their platform sales as marketplace facilitators, but your own-website sales are your responsibility. Five states have no statewide sales tax.
Whether SaaS, digital goods and services are taxable varies widely by state. A nexus study maps your sales by state against thresholds and product taxability before you register.
We run the study, register where needed, configure tax collection in your store or billing system, and file returns on each state's schedule.
