Quick Reference & Frequently Asked Questions
Do Amazon FBA and TikTok Shop sales count toward my Shopify store's state sales tax nexus?
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.
How does the 200-order threshold trap low-AOV ecommerce brands?
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.
Why does storing inventory in a 3PL or Amazon FBA warehouse trigger immediate sales tax nexus?
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.
When is registering in a borderline state more expensive than the tax exposure itself?
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.
