What is Wyoming's e-commerce sales tax in 2026?

Wyoming's 2026 e-commerce sales tax: out-of-state sellers collect once they cross $100,000 in Wyoming-destination revenue. As a remote seller, charge the 4.00% state rate plus any applicable local rate at the buyer's ship-to address.

Do I collect sales tax on every Wyoming order?

You collect Wyoming sales tax once you cross the economic nexus threshold ($100,000). Below threshold, you don't need to collect unless you have physical nexus (office, employees, inventory in Wyoming).

What rate do I charge for Wyoming e-commerce sales?

For sales shipped into Wyoming from out of state, charge the 4.00% state rate plus any applicable local rate at the buyer's ship-to address. Most e-commerce platforms (Shopify, WooCommerce) can apply destination rates automatically when you enable WY in tax settings. Sales that both begin and end inside Wyoming can follow a different sourcing rule in a minority of states — check with the Wyoming Department of Revenue if you are an in-state seller.

Do I need to collect sales tax on shipping in Wyoming?

It depends on state-specific rules. Many states tax shipping when the product is taxable; some states exempt shipping if separately stated. Check Wyoming's specific policy or use a tax service that encodes the rule.

If your E-commerce business sells $100,000 into Wyoming in a calendar year, you have economic nexus and must register, collect, and remit Wyoming sales tax.

E-commerce sales tax basics in Wyoming

For a direct-to-consumer store (Shopify, WooCommerce, BigCommerce, or custom) shipping to Wyoming buyers, the economic nexus trigger is $100,000 in WY-destination revenue (effective 2024-07-01). Crossing that bar obligates registration, collection, and periodic filing.

Once registered, charge 4.00% state tax plus the applicable local rate — averaging 1.56% across Wyoming but varying by the buyer's shipping ZIP on most tangible personal property. Digital products, subscriptions, and professional services have different treatment — see the Wyoming SaaS page if you sell software or digital goods.

Registration + collection checklist

Register with the Wyoming Department of Revenue for a sales tax permit.
Configure your cart platform to collect tax at the destination rate. Enable WY in your tax settings.
As a remote seller, charge the combined state + local rate at the customer's delivery address — interstate sales are sourced to the destination, not to where you ship from.
File returns on the cadence your DOR assigns (monthly, quarterly, or annually).
Track your Wyoming-sourced revenue monthly so you know when you're approaching or below threshold for the next period.

Common mistakes e-commerce sellers make in Wyoming

Using origin-based rates (your HQ state's rate) instead of destination rates. A sale shipped from outside Wyoming into Wyoming is sourced to the buyer's delivery address, so charge the WY rate, not your home state's. Intrastate sales are a separate question: a minority of US states apply origin sourcing to sales that both begin and end in-state, so if your business is located in Wyoming, confirm the intrastate rule with the Wyoming Department of Revenue before configuring your cart.
Guessing at how marketplace sales count toward the Wyoming threshold. States split on this — some let a seller exclude sales a registered marketplace facilitator already collected on, others require those sales to be included in the threshold test even though the marketplace remits the tax. Read Wyoming’s own rule on the Wyoming marketplace facilitator page before adding or removing them from your nexus-tracking spreadsheet.
Waiting until year-end to register. Registration and collection deadlines run from the threshold-crossing date, and the length of that grace period is set by each state — some require collection on the very next transaction, others allow until the first day of a later month. Check Wyoming’s deadline with the DOR as soon as you cross $100,000; back-tax exposure accrues for every day you sell unregistered.
Forgetting to file zero returns once registered. Missing filings trigger penalties even when you owe no tax.

Wyoming nexus note

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.
