Wyoming sales tax starts at a 4% state rate, with city, county, and special-district additions bringing most purchases to roughly 5% to 6% at the register.1Justia. Wyoming Code 39-15-104 – Taxation Rate It applies to tangible goods and a specific list of services, with meaningful exemptions for groceries, prescriptions, agriculture, manufacturing inputs, and resale inventory. The Wyoming Department of Revenue’s Excise Tax Division licenses sellers, collects the tax, and enforces the rules.
Rates You Actually Pay
The 4% state rate applies statewide to every taxable sale. On top of that, counties and municipalities can add voter-approved general-purpose, specific-purpose, and economic development taxes. The combined rate averages about 5.56% across Wyoming. Some resort areas and jurisdictions with multiple local levies run above 6%; a few locations sit at the 4% floor.
Before pricing a product or budgeting a large purchase, check the Excise Tax Division’s rate chart for the specific city or county where the sale takes place. The right rate depends on where the buyer takes delivery, not where the seller is based.
Wyoming also charges a use tax at the same rate. If you buy something out of state or from an online seller that doesn’t collect Wyoming tax, you owe use tax when you bring the item into Wyoming or use it here.1Justia. Wyoming Code 39-15-104 – Taxation Rate The purpose is to keep Wyoming retailers from being undercut.
What’s Taxable
The core of the tax is tangible personal property: clothing, furniture, appliances, building materials, vehicles, and other physical goods sold at retail. If you’re selling physical products in Wyoming, assume the sale is taxable unless a specific exemption applies.
Wyoming also taxes a defined set of services and transactions:2FindLaw. Wyoming Statutes Title 39 Taxation and Revenue 39-15-103
- Labor to repair, alter, or improve tangible personal property, including auto repair, appliance servicing, and equipment maintenance.
- Restaurant meals, at the full price excluding tips.
- Lodging for transient guests at hotels, motels, and short-term rentals.
- Admissions to sporting events, concerts, amusement parks, and other entertainment venues.
- Public utility charges for gas, electricity, and heat.
- Intrastate telecommunications services.
- Services and property used on oil and gas well sites, from production casing through abandonment.
Digital goods are taxable when the buyer gets permanent use. A downloaded song, movie, e-book, or piece of software you keep is treated like a physical copy. Streaming subscriptions, where access ends when you cancel, generally don’t meet the permanent-use test and aren’t taxed.3Cornell Law. 011-2 Wyoming Code R 2-12 – Specific Taxability Issues Digital codes and gift cards redeemable for downloads are taxed the same as the underlying product.
What’s Exempt
Several exemptions save real money if you know to claim them.
Food and Medical
Food for home consumption is exempt from state sales tax.4Justia. Wyoming Code 39-15-105 – Exemptions Groceries aren’t taxed; restaurant meals are.
Prescription drugs, insulin, medical oxygen, blood plasma, prosthetic devices, hearing aids, eyeglasses, contact lenses, mobility equipment, and durable medical equipment are exempt when sold under a prescription. Over-the-counter drugs don’t qualify. Noncapitalized medical supplies and disposable items used in direct patient care are also exempt, while office supplies and capitalized equipment used in general practice operations are not.
Agriculture
Livestock feed, poultry feed used for marketing, seeds, fertilizer, and small plants grown to produce crops for sale are exempt. Farm implements, meaning tractors and machinery designed and used exclusively for agricultural operations, are exempt as well. Titled motor vehicles, ATVs, snowmobiles, and lawn tractors don’t qualify. Power and fuel consumed directly in agricultural operations are also exempt. To claim any of these, the buyer gives the seller an exemption certificate at the time of purchase.
Manufacturing
Machinery used directly and predominantly in manufacturing tangible personal property in Wyoming is exempt through December 31, 2042. Raw materials and components that become part of a finished manufactured product are exempt, along with containers, labels, and shipping cases used for those products. Chemicals and catalysts consumed during manufacturing qualify too.
Resale, Government, and Nonprofits
Inventory purchased for resale is exempt; tax is collected only at the final sale to the consumer. The buyer gives the supplier a valid exemption certificate.
Purchases by Wyoming state and local governments, the federal government, and qualifying religious or charitable organizations are exempt. Nonprofit organizations providing meals or services to senior citizens also qualify when certified by the relevant state agencies.
When Out-of-State Sellers Must Collect
If you sell into Wyoming from another state, track your Wyoming sales volume. Following the U.S. Supreme Court’s 2018 decision in South Dakota v. Wayfair, Wyoming requires remote sellers to register and collect once they cross either threshold in the current or prior calendar year: $100,000 in gross revenue from sales delivered into Wyoming, or 200 or more separate transactions delivered into the state.5Justia. Wyoming Code 39-15-107 – Compliance Hitting either trigger means you must register with the Department of Revenue and collect tax on future sales.
Since July 2019, marketplace facilitators such as Amazon and Etsy are treated as the seller on every sale they facilitate in Wyoming. The facilitator collects and remits for its third-party sellers once the platform’s own sales, or the combined sales of its marketplace sellers, meet the same economic nexus thresholds. If a facilitator already collects Wyoming tax on your sales, you don’t collect again on those. But if you also sell directly through your own website, your direct sales count separately toward the nexus thresholds.
Registering as a Seller
Before making your first taxable sale, you need a Wyoming sales tax license. Registration goes through the Wyoming Business Registration process with the Department of Revenue. You’ll provide your Federal Employer Identification Number (or Social Security Number for sole proprietors), the legal names and addresses of all owners, your NAICS code, your expected start date, and estimated monthly sales.
The department assigns your filing frequency based on expected volume. Sellers who expect to collect less than $150 per month in tax may qualify for quarterly or annual filing instead of monthly.5Justia. Wyoming Code 39-15-107 – Compliance
Filing and Paying
Wyoming handles sales tax returns and payments through the Wyoming Internet Filing System (WYIFS).6Wyoming Department of Revenue. Wyoming Internet Filing System
Monthly filers must file and pay by the last day of the month following the reporting period. Tax collected in January is due by the last day of February. Quarterly filers face deadlines of January 31, April 30, July 31, and October 31. Annual filers must submit by January 31 of the following year.7Cornell Law. 011-2 Wyoming Code R 2-5 – Reporting If a deadline falls on a weekend or holiday, it moves to the next business day.
Vendor Compensation Credit
File and pay by the 15th of the month a return is due and you can keep a portion of what you collected. The credit is 1.95% of the first $6,250 in tax owed, then 1% on anything above that, capped at $500 per month.8Wyoming Department of Revenue. Vendor Compensation Bulletin Your account must be in good standing, with all returns filed and balances paid. If you hold multiple licenses, the Department of Revenue recommends a consolidated return so the credit calculates correctly.
Penalties for Late or Wrong Filings
Missing deadlines or underreporting gets expensive quickly. Wyoming distinguishes between mistakes and intentional avoidance:9Justia. Wyoming Code 39-15-108 – Enforcement
- A deficiency from carelessness or disregard of the rules, without fraudulent intent, carries a 10% penalty plus interest.
- An intentional underpayment carries a 25% penalty plus interest.
- A missed filing deadline triggers a department notice. Filing within 30 days of that notice costs a $10 penalty; failing to file within 30 days raises it to $25.
Interest accrues on unpaid balances at the average prime rate from the preceding fiscal year plus four percentage points. The Excise Tax Division posts the current year’s rate on its website. The flat late-filing fees look modest, but combined with interest and the loss of vendor compensation, falling behind compounds fast.
Vehicle purchases run on a separate timeline. Buyers who don’t pay sales tax within 65 to 75 days of the sale owe a $25 civil fee to the county treasurer. After day 75, the fee becomes $25 or 10% of the tax due, whichever is greater.
