Buying a vehicle out of state? Please don’t wait for your temporary registration to expire.

We are seeing more out-of-state dealers issue temporary registrations that are good for 90 days or longer. However, Wyoming sales tax rules are different.

In Wyoming, sales tax on a vehicle must generally be paid to the County Treasurer’s Office within 65 days of the purchase date to avoid penalties and interest.

That means your out-of-state temporary registration may still be valid, but your Wyoming sales tax deadline may already be approaching.

To avoid extra costs, please come in and pay your sales tax before day 65 after the purchase date. Bring your purchase paperwork, title paperwork if available, and any temporary registration documents you received from the dealer.

If you are unsure of your deadline, please contact the Treasurer’s Office and we will be happy to help you review your paperwork.

Reminder: The temporary registration expiration date does not extend the Wyoming sales tax deadline.

FOR IMMEDIATE RELEASE

Governor Gordon Urges Property Tax Refund Program Applications

“We are putting money back on the kitchen table for folks who need it. If you are eligible, I encourage you to sign up.”

CHEYENNE, Wyo. - April 27, 2026 - Governor Gordon (R-WY) encourages eligible property owners to apply for the Wyoming Property Tax Refund Program by the June 1st deadline. This program provides refunds on a qualified basis to Wyoming homeowners who paid taxes for the 2025 tax year. If homeowners applied last year, the Wyoming Department of Revenue (DOR) recently sent out hardcopy applications.

In the 2026 Budget Session, the Wyoming Legislature accepted the Governor’s recommendation of $12 million for property tax relief targeted to lower-income homeowners. Generally, this includes Wyoming residents who make 145% or less of the median household income in their county or the statewide median household income, whichever is greater. DOR estimates that the average statewide refund amount for the 2025 tax year will be $771.35. However, this amount will vary by county and specific amounts for each county can be found on DOR's website.

“The refund program is a strong example of targeted and responsible property tax relief,” said Governor Gordon. “We are putting money back on the kitchen table for folks who need it. If you are eligible, I encourage you to sign up.”

“Thanks to strong support from Governor Gordon and funding from the legislature, the Property Tax Refund Program is now in full swing,” Director of the Department of Revenue Bret Fanning said.

While the income thresholds vary by county, an annual household income under $114,043 generally qualifies in most areas. Please contact your local county treasurer or the Department of Revenue for more information about the other eligibility requirements with this program. Eligible applicants can receive hundreds of dollars back in meaningful property tax relief.

Property taxes in Wyoming are primarily used at the local level, supporting critical services that residents rely on every day. These include K-12 public schools, local law enforcement and emergency services, road and bridge maintenance, hospitals and public health services, community colleges and local government operations.

Unlike many other states, Wyoming does not collect a personal income tax, making property taxes one of the primary ways communities fund essential services.

However, having robust residential property tax relief programs that help veterans, the elderly and families in need is an important tool for strengthening our families and communities. The Governor recommends families in need take full advantage of these other programs as well. Home owners can reach out to their county assessor’s office.

To find more information on the Property Tax Refund Program and to submit an application, residents can fill out the hardcopy application sent to them, go to their local county treasurer’s office, or visit the Wyoming Department of Revenue website: https://revenue.wyo.gov/.
