Sheridan, Wyoming Sales Tax Rate

Sheridan is in north-central Wyoming at the foot of the Bighorn Mountains. The economy is driven by tourism (Bighorn Mountains, King's Saddlery, historic downtown), energy (coal bed methane, coal), agriculture (ranching), and healthcare.

The combined sales tax rate in Sheridan is 6.000%, composed of the Wyoming state rate of 4.000% plus a local portion of 2.000%.

The formula to calculate sales tax for any purchase:

For a $150.00 purchase in Sheridan: tax is $9.00 ($150.00 × 0.06000), total is $159.00.

Sheridan's tourism and rodeo operations buy heavy equipment where the exemption question decides project economics — at a 6.000% combined rate, tax on a single compressor package can exceed a service truck's price.

The exemptions cluster around direct use: equipment doing the extracting, moving or processing — rigs, compressors, pumps, meters, refinery plant — is the part most states relieve, and equipment supporting the people who operate it is the part they do not. Two categories sit outside that logic and are worth checking separately in Wyoming: pollution-control plant, which is often exempt because regulation mandates it rather than because it produces anything, and renewable generation, which is more often incentivised than exempted — a different mechanism with different paperwork. Where a purchase falls is a Wyoming determination; the production and manufacturing exemptions guide covers how direct use is drawn.

Energy projects sited around Sheridan can stack:

• Investment Tax Credit (ITC) — federal 30% for solar, wind, battery storage
• Production Tax Credit (PTC) — federal per-kWh for wind, geothermal
• Wyoming state-specific incentives — sales tax exemptions on equipment
• Property tax abatements for qualified energy projects

Sheridan shoppers and businesses routinely cross into Buffalo, Gillette, Cody and beyond — and in Wyoming, the combined rate can change at those lines. Of the tracked neighbors, Buffalo charges 5.000%, Gillette charges 5.000% and Cody charges 4.000% versus Sheridan's 6.000%.

• Buffalo (30 mi S): combined rate 5.000% — see the Buffalo page
• Gillette (100 mi NE): combined rate 5.000% — see the Gillette page
• Cody (120 mi W): combined rate 4.000% — see the Cody page
• Billings MT (130 mi N): outside our tracked Wyoming city set — verify its current combined rate before invoicing deliveries there
• Ranchester (15 mi N): outside our tracked Wyoming city set — verify its current combined rate before invoicing deliveries there

Deliveries are taxed by the destination rules Wyoming applies, not by where the store sits — when an order ships across one of these city lines, re-check the rate for the exact address.

Since South Dakota v. Wayfair, a seller with no premises, staff or stock anywhere near Sheridan can still be required to register in Wyoming and charge 6.000% on what it ships here — presence stopped being the trigger and volume took over. The thresholds that decide it are in the table below; what they do not tell you is that crossing them obliges you to collect at the buyer's local rate, not a state average, which is why Sheridan and its neighbours have to be priced separately. The registration mechanics and the trailing-twelve-month counting rules are in the economic nexus guide.

Audit & Compliance Warning: Because combined tax rates combine state and local tax components, calculating tax based purely on ZIP codes can lead to errors. Many ZIP codes span multiple municipal boundaries with differing rates. For precise auditing, always use address-level geo-lookup.

Three obligations follow the 6.000% rate around Sheridan: untaxed out-of-state purchases delivered here owe matching use tax — $60.00 on a $1,000 order — self-assessed to WY Dept of Revenue / Sheridan County; sellers with physical presence or economic nexus must register before collecting; and wholesale sales need a valid resale certificate on file at transaction time. Filing mechanics, exemption certificates, and audit preparation are covered in the Wyoming sales tax guide.

Prescription drugs are exempt from sales tax in Wyoming. Medical equipment purchased by licensed providers in Sheridan may qualify for exemptions — verify with WY Dept of Revenue / Sheridan County.

While not primarily a tourism destination, Sheridan draws visitors for Bighorn Mountains and King's Saddlery and Don King Museum, and the 6.000% rate applies to their spending on lodging, dining, and attractions.
