Understanding sales tax nexus for sellers
Since South Dakota v. Wayfair, most US states require remote sellers to register once they exceed economic nexus thresholds — typically based on revenue or transaction count. Physical presence through FBA inventory, employees, or affiliates can also create nexus independent of revenue.
Amazon and other marketplaces may collect tax on your behalf in some jurisdictions, but direct sales, certain categories, and specific states may still require your own permit. Sellers in Pakistan operating US marketplace businesses benefit from a structured nexus review before scaling inventory into high-volume states.
ECOMHUTSY coordinates permit applications using your LLC, EIN, and business address records. Because each state charges different fees, pricing is confirmed only after our support team reviews your consultation request.
