US sales tax nexus checker

Selling on Amazon USA from India? Find out which states legally require you to register and collect sales tax based on your revenue. 46 states + DC covered.

💡 Good news for Amazon FBA sellers:

All 46 sales-tax states have Marketplace Facilitator laws — meaning Amazon collects and remits sales tax for you on Amazon sales. You usually only need to register if you sell on your own site OR cross specific thresholds. This tool checks both.

Your nexus status by state

What is economic nexus?

Economic nexus is a rule from the 2018 South Dakota v. Wayfair Supreme Court ruling. It says a state can require you to register and collect sales tax once you cross a threshold of either revenue or transactions in that state — even without a physical presence.

Most states use: $100,000 in sales OR 200 transactions in the past 12 months. Some are higher ($250K-$500K). Five states have no sales tax at all (NH, OR, MT, AK, DE).

Marketplace Facilitator

Amazon, Walmart, Etsy all collect and remit sales tax on your behalf. You usually don't have to file in those states unless you also sell off-platform.

FBA inventory = physical nexus?

Yes, technically. Amazon storing your goods in a state warehouse can create physical nexus. But most states now exempt FBA sellers from registration if marketplace facilitator law covers it.

Off-Amazon sales

Shopify, your own site, wholesale — these are NOT covered by marketplace facilitator. You're personally responsible for collecting sales tax once you cross nexus thresholds.

Disclaimer

This is general guidance, not legal/tax advice. Rules change. Talk to a US sales tax CPA (we can refer one) before registering or filing.
