Credit card processing and merchant services in Cheyenne, WY
Cheyenne's sales tax is Wyoming's 4% plus Laramie County's pennies, and the county's specific purpose penny ends once its projects are paid for, so your POS rate can shift.
The Census Bureau estimated 66,507 people in Cheyenne in July 2025. The sales tax they pay at your register is assembled from pieces. Wyoming's statewide rate is 4%. Laramie County adds its "5th penny," a 1% general purpose tax that county voters first approved in 1977 and that pays for general county operations.
Then there's the 6th penny, a specific purpose sales and use tax that pays for projects voters approve on the ballot. The county describes it as temporary. It stays in effect only until enough has been collected for the approved projects, which takes about five years on average, and then it ends on its own. Laramie County voters weighed new 6th penny propositions on the August 2026 primary ballot, and the county estimates that about 40% of 6th penny revenue comes from visitors and tourism.
For a Cheyenne merchant, that means the rate in your POS isn't fixed for good. When a specific purpose tax starts or runs out, every terminal, online checkout and invoice template has to change with it. Check the Excise Tax Division's sales and use tax rate charts before you set a rate, and again after any county tax vote.
Card fees face fewer moving parts. We found no Wyoming statute on surcharges, so Visa's and Mastercard's rules decide: your cost or 3% on Visa, your cost or 4% on Mastercard, and nothing on debit. Our Wyoming page has the sources. If you'd rather cut costs than add a fee, start with a free statement review and compare your rate with interchange-plus pricing.
Rules that matter in Cheyenne
Laramie County optional sales taxes

The 6th penny is a specific purpose sales and use tax that funds ballot-approved projects.

Common questions
What sales tax rate should I set for a Cheyenne store?
Start with Wyoming's 4%, add Laramie County's 1% general purpose tax, then add any specific purpose tax in effect on the day you set up. Because the 6th penny ends once its projects are funded, and voters considered new propositions in August 2026, check the Excise Tax Division's current rate chart instead of copying last year's receipts.
Why would the Cheyenne sales tax rate change without a new state law?
Because the county's 6th penny is designed to expire. Laramie County collects it only until the voter-approved projects are paid for, about five years on average, and then it stops on its own. A new specific purpose tax takes another county vote. Either event changes the rate your terminals and online checkout should charge.
How much can a Cheyenne shop charge for paying by credit card?
No more than your own cost, under the card network rules, since we found no Wyoming statute on surcharges. Visa's ceiling is 3% and Mastercard's is 4%, but if your actual Visa cost is 2.5%, then 2.5% is your Visa limit. Post notice at the entrance and the register, list the fee on the receipt, and skip debit cards.
How can a Cheyenne business take payments away from the counter?
For deliveries and service calls, mobile payments let you tap or insert a card on a phone or a small reader. For phone orders and invoices, a virtual terminal handles card payments, payment links and recurring billing. Set each one to the current rate for the county where the sale happens, which may not be Laramie County.
