State

Trailing-12-mo gross sales

All my sales in this state come through a marketplace (Etsy, Amazon, eBay, Faire, TikTok Shop, Walmart). The marketplace collects and remits sales tax on your behalf — you typically owe no direct registration in marketplace-facilitator states. Direct-store sales (Shopify, BigCommerce, WooCommerce, your own checkout) are not marketplace-facilitated — those count toward your own threshold and need a separate entry. Uncheck this if any portion of your sales in this state ran through your own store.

Over threshold — register and file

You are over $500,000 in sales into California. Register for a California sales-tax permit and begin filing.

Educational tool only — not tax advice. Economic-nexus thresholds, marketplace-facilitator carve-outs, and lookback periods change every legislative session and vary materially between states. The "Marketplace covered" carve-out assumes 100% of your sales in that state come through a marketplace facilitator that collects and remits — a single direct Shopify or website sale into a state where you exceed the threshold can still create a separate registration obligation. Always verify against the state Department of Revenue and consult a qualified state-and-local-tax professional before registering, filing, or skipping a filing.
