Specific answers for teams replacing TaxJar with NexusGuard Studio.
In every state with a sales tax, Marketplace Facilitators (Amazon, TikTok Shop, Walmart, Etsy) are legally required to collect and remit sales tax on marketplace orders. While a few states include gross marketplace sales in the initial threshold test, most states exclude marketplace revenue when determining whether your direct Shopify store must register—saving you thousands in unnecessary filing fees.
While states like California, Texas, New York, and Pennsylvania have eliminated the 200-transaction rule or raised thresholds to $500,000, many states still enforce a '$100,000 OR 200 orders' rule. If your average order value is $25, just 200 orders ($5,000 in sales) technically crosses the transaction threshold.
Holding physical inventory in a third-party fulfillment center creates Physical Nexus in that state from day one—even if your sales in that state are well below $100,000. Auditing your 3PL warehouse states alongside economic thresholds prevents uncollected back-tax surprises.
If you barely cross 200 small orders in a state with $4,500 in taxable sales (~$330 in annual tax), registering immediately locks you into $350–$600 per year in monthly or quarterly filing fees plus CPA prep costs. Our calculator helps you quantify the exact dollar exposure vs compliance overhead.
No. All state threshold checks, Marketplace Facilitator deductions, and back-tax calculations run 100% locally inside your browser. Zero sales figures or customer data ever leave your computer.
TaxJar and Avalara charge $99 to $299+ every month just to monitor nexus and manage returns, and automatically bump your monthly bill when order volume grows during Q4. NexusGuard Studio is a $19 one-time buyout (or €3.99 24-hour pass) with a 14-day refund guarantee.
