Wyoming Dropshipping Sales Tax Guide — 2026

Dropshipping into Wyoming raises three distinct tax questions. First, you (the retailer) have to collect and remit Wyoming sales tax on your retail sales if you exceed $100,000. Second, your dropship supplier may charge YOU sales tax on the wholesale invoice if they have Wyoming nexus and you can't present a valid resale certificate. Third, the marketplace (if any) handles its own tax on facilitated transactions.

Wyoming applies 4.00% as the base state rate; local add-ons average 1.56%.

• If you have a Wyoming sales tax permit, you can usually issue your dropshipper a WY resale certificate to avoid being charged sales tax on the wholesale invoice.
• Some states (notably California, Florida, Massachusetts, Tennessee, and a few others) require the buyer to hold an IN-STATE registration before issuing a resale certificate — a home-state certificate isn't enough.
• Streamlined Sales Tax (SST) states accept the uniform Multistate Certificate; others have their own forms.

• Treating your dropshipper's nexus as if it obligates them to collect from the end customer — no, they invoice you at wholesale; you invoice the customer at retail. Only the retail transaction is subject to collection duty.
• Forgetting that your retail revenue into Wyoming still counts toward the economic nexus threshold, independent of the dropshipping arrangement.
• Not keeping resale certificates on file — your supplier will charge you tax (and you'll have already collected from the customer), eroding margin.

Wyoming sales tax nexus and economic nexus threshold: effective July 1, 2024, an out-of-state seller without Wyoming physical presence must remit Wyoming sales tax once gross revenue from taxable tangible personal property, admissions, or services delivered into Wyoming exceeds $100,000 in the current or immediately preceding calendar year. Wyoming repealed the prior 200-transaction test, so the current remote-seller trigger is sales-only. Marketplace facilitators are treated as vendors for facilitated marketplace sales and must collect and remit Wyoming sales tax on sales they facilitate into Wyoming, subject to the remote-seller limitations in W.S. 39-15-501.
