Tax landscape for small businesses
The Wyoming Department of Revenue's Excise Tax Division publishes its sales tax documents as files linked from excise-tax-div.wyo.gov. This guide quotes four of them: the rate chart titled "Sale/Use and Lodging Tax Rates by Locality Effective Date 10/01/2026" (linked as "October 2026" on the Sales/Use/Lodging Tax Rate Charts page), the next chart, titled "Sale/Use and Lodging Tax Rates by Locality Effective Date 01/01/2027" (linked as "January 2027" on the same page), the "Instructions Return 41" file (linked from the returns page) and the "Application - Regular Vendors" file (linked from the registration page). Each Wyoming figure below carries the date its document shows. Check the current documents before you file; the Department or a tax professional can confirm how they apply to you.
Every county row of the rate chart (Wyoming, Department of Revenue rate chart effective October 1, 2026) starts with 4% in its "State Tax Rate" column, and county options are added to it. Three rows as printed: "Natrona 4% + 1% = 5%", "Park 4% = 4%" and "Teton 4% + 1% + 2% = 7%". The Form 41 instructions (Wyoming, Department of Revenue Form 41 instructions, revised 7.10.24) say returns use county codes "as tax is only imposed at the state and county level".
Sample invoice, worked through: a business in Natrona County bills $800.00 of taxable goods. Natrona's row reads "Natrona 4% + 1% = 5%" on the chart (Wyoming, Department of Revenue rate chart effective October 1, 2026) and again on the chart (Wyoming, Department of Revenue rate chart effective January 1, 2027), so with that 5% total, tax is $800.00 × 5% = $40.00 (the 4% state part is $32.00 and the 1% county part is $8.00), and the invoice total is $840.00. The figures are invented for illustration.
The rates in that example are read from the Department's charts. On saving your own tax settings, Billed's invoice software page says: "Save your tax rates and settings once, and Billed calculates taxes automatically when you create invoices and estimates."
Tax overview
Each row lists a tax area and its notes. Confirm current figures with your state's tax agency or the IRS.
| Tax type | Rate or basis | Notes |
|---|---|---|
| State sales and use tax | "4%" | Rate chart (Wyoming, Department of Revenue rate chart effective October 1, 2026): every county row starts with 4% in the "State Tax Rate" column, e.g. "Natrona 4% + 1% = 5%". |
| County option taxes | Varies by county (see notes) | Rate chart (Wyoming, Department of Revenue rate chart effective October 1, 2026) examples: "Park 4% = 4%", "Goshen 4% + 1% + 0.25% = 5.25%", "Albany 4% + 1% + 1% = 6%", "Teton 4% + 1% + 2% = 7%". |
| Resort district tax | Two resort districts (see notes) | Rate chart (Wyoming, Department of Revenue rate chart effective October 1, 2026): "The Resort District Taxes are applied to all taxable sales and services within the two Wyoming Resort Districts, Grand Targhee and Teton Village." Its Teton Village row reads "4% + 1% + 2% + 2% = 9%". |
| Use tax | See notes | Form 41 instructions (Wyoming, Department of Revenue Form 41 instructions, revised 7.10.24): "Use tax is due on items purchased out of state and brought into Wyoming for storage, use, or consumption where no tax or not enough tax was charged by the vendor at the time of purchase." |
| Federal self-employment tax | "15.3%" | In the US (federal), the IRS self-employment tax page (updated October 30, 2026): "The self-employment tax rate is 15.3%." |
Filing requirements
This list isn't a complete checklist for your business.
Get a sales/use tax license
The Excise Tax Division's FAQs (Wyoming, as retrieved on November 1, 2026) say a business needs a Wyoming sales tax license "If your company is selling something with an imposition statute and your company has a physical presence or connection to Wyoming (outside of a registered agent or virtual office) or meets our economic thresholds". They add: "Simply creating a business entity in Wyoming doesn’t automatically mean your company needs a Wyoming sales tax license." The Department's "Application - Regular Vendors" form (Wyoming, Department of Revenue license application, Rev 5/04/2023) says: "Include the $60.00 non-refundable application fee."
File every period, even with no sales
The Form 41 instructions (Wyoming, Department of Revenue Form 41 instructions, revised 7.10.24) say: "All returns must be postmarked by the last day of the month following the last month in the reporting period." They add: "As a licensed vendor, you must file a return even if there were no sales or taxes to report."
Late payment and late filing
Per the same instructions (Wyoming, Department of Revenue Form 41 instructions, revised 7.10.24): "Penalty for paying tax after the due date is 10% of the total tax due. Penalty for not filing the return by the due date is $10.00."
Federal estimated tax
In the US (federal), the IRS estimated taxes page (updated September 25, 2026) says: "Individuals, including sole proprietors, partners, and S corporation shareholders, generally have to make estimated tax payments if they expect to owe tax of $1,000 or more when their return is filed."
Deductions and write-offs
Confirm with your state how it treats each item.
- Exemption certificates: the Department's Sales/Use/Lodging Exemption Matrix (Wyoming, updated August 26, 2026) says: "As of July 1, 2006, the Streamlined Sales and Use Tax Agreement exemption certificate is the only exemption certificate approved in Wyoming." It adds: "Exemption certificates shouldn't be sent to our agency; rather they must be fully completed by taxpayers and given to vendors at the time of transaction. In turn, vendors must preserve these exemption certificates in their records for audit purposes."
- Buying for resale: the Excise Tax Division's FAQs (Wyoming, as retrieved on November 1, 2026) say: "Licensed vendors can properly fill out that exemption certificate and claim a resale exemption for purchase items without sales tax from their suppliers. Unlicensed vendors wouldn’t have the ability to properly claim a resale exemption using Wyoming information."
- SE tax and your AGI: In the US (federal), the IRS self-employment tax page (updated October 30, 2026) says: "You can deduct the employer-equivalent portion of your self-employment tax in figuring your adjusted gross income."
- What to keep: In the US (federal), the IRS recordkeeping page (updated May 1, 2026) says: "You must be able to prove certain elements of expenses to deduct them."
Practical tips
- Pay early for the vendor credit. The Form 41 instructions (Wyoming, Department of Revenue Form 41 instructions, revised 7.10.24) say: "Vendors are allowed to take a credit of 1.95% of the total tax due (not taxable sales) up to a total vendor compensation credit of $500.00 per filing period per vendor", and the credit line "is only to be used if the return and payment are going to be postmarked by the 15th of the month the tax is due."
- Use the chart for the quarter you're reporting: the Form 41 instructions (Wyoming, Department of Revenue Form 41 instructions, revised 7.10.24) tell vendors to "Refer to the sales/use tax rate chart with the effective date that corresponds to the reporting quarter".
- Bought supplies out of state without tax? The Form 41 instructions (Wyoming, Department of Revenue Form 41 instructions, revised 7.10.24) cover that under use tax, which is reported in its own column of the return.
- Keep a copy of each return and the rate chart you used next to the invoices for that period.

When this isn't for you
This guide stops at sales, use and the vendor return. Lodging tax, Wyoming entity filings, property and mineral taxes, and anything specific to your industry aren't covered; for those, and for your own returns, contact the Wyoming Department of Revenue or a tax professional.
