Do you sell through Amazon, Etsy, eBay, Walmart, app stores, or another online marketplace that handles checkout?
Post-Wayfair, every state with a sales tax now has a marketplace-facilitator law that commonly shifts the duty to collect and remit to the platform on facilitated sales - your own selling channels are treated separately.
Use the interactive tool above to see how this applies to your situation.

Do you also sell directly off the marketplace - your own website, in person, wholesale, phone, or social-media orders you invoice yourself?
A facilitator only collects on sales it processes; any channel where you take the order and money yourself is your own economic-nexus responsibility to test and, where met, to collect on.
Rely on facilitator collection on facilitated sales, but keep the collection reports as proof and re-screen the moment any off-platform sale occurs (state marketplace facilitator laws; South Dakota v. Wayfair, 585 U.S. 162 (2018)).

In any single state, do your direct (off-marketplace) sales alone exceed roughly $100,000 a year, or the state's own dollar or transaction threshold?
Economic nexus is commonly cited around $100,000 or 200 transactions per state, but several states use only a dollar test or a higher figure and many no longer count the 200-transaction trigger - confirm each state's current threshold.
Track direct sales per state and register the moment a state's economic-nexus threshold is crossed (South Dakota v. Wayfair, 585 U.S. 162 (2018)).

Have you already registered and begun collecting sales tax on those direct sales in the states where you cross the threshold?
Once a direct-sales threshold is met, the seller - not the marketplace - must register, collect, file, and keep valid resale or exemption certificates; unremitted tax on past direct sales is a personal-liability trust-fund exposure that a lookback can reach.
Keep both streams filed correctly and reconcile facilitator reports against your own returns so facilitated sales are deducted and not double-remitted. Quantify unremitted trust-fund tax on past direct sales and weigh a voluntary disclosure agreement before you register (South Dakota v. Wayfair, 585 U.S. 162 (2018)).

Across all your own direct channels, do sales into any single state exceed roughly $100,000 a year, or that state's dollar or transaction threshold?
With no marketplace in the picture, nothing collects tax for you - each state's economic-nexus threshold (commonly cited near $100,000 or 200 transactions, but confirm current figures) is the line where you must register and collect yourself.
Register and collect in each state where your direct sales cross the economic-nexus threshold (South Dakota v. Wayfair, 585 U.S. 162 (2018)). Track sales by state and register as soon as a state's economic-nexus threshold is crossed (South Dakota v. Wayfair, 585 U.S. 162 (2018)).
