You launched on Shopify, expanded to Amazon FBA, and hit $2M in revenue. You likely now have economic nexus in 12 states, physical nexus from Amazon inventory in 8 more, and an obligation to file monthly returns in jurisdictions you have never visited.

Amazon, Walmart and Etsy collect tax under marketplace facilitator laws. But in states like California, Texas and Washington, those sales still count toward your economic nexus threshold. That triggers a requirement to register and file returns for your direct Shopify sales.

Economic nexus means a state can require you to collect and remit its sales tax because of how much you sell into it, even if you have no office or staff there. Since the 2018 South Dakota v. Wayfair decision, 45 states and DC have adopted rules like this. The most common trigger is $100,000 in sales into the state, though California, Texas and New York use $500,000.
Often, yes. Marketplace facilitators collect tax on the orders they process, but many states still count those sales toward your threshold. Once you cross it, you register and file for your direct sales, such as Shopify orders, and report the marketplace sales as exempt. Vertexis Nexus separates the channels so the return reflects both.
Registration deadlines are set by each state, and some start the clock the day you cross the threshold. Vertexis Nexus alerts you at 75%, 90% and 100% of each threshold, so you have time to register before you owe tax on uncollected sales.
Rates are calculated at the rooftop address level across more than 11,000 state, county, city and special-district jurisdictions. Returns include the local breakdown each state asks for, including home-rule filings where they apply.
We can prepare back returns for periods where you already had a filing obligation. If your look-back exposure is large, a Voluntary Disclosure Agreement is usually the better route, and we recommend working with a qualified SALT professional on it. Our VDA guide explains the process.
Store connections use read-only order access. State portal logins and bank tokens are stored in an encrypted vault using AES-256-GCM, with keys held in an HSM. You authorize each state before we file anything, and you can revoke access at any time.
