What You Need Before You Go
When the car registration renewal showed up in the mail, the number on it made no sense. After calling the county treasurer's office and getting escalated to a supervisor (the first person couldn't explain it either), we finally cracked the formula. Here's everything you need to know.
Head to the county treasurer's office (in the courthouse building in Cody) with:
- VIN inspection — get this at the local police station first. Costs ~$15-20. They run a background check on the vehicle.
- Proof of insurance
- Current registration from your previous state
- Optional: Wyoming title ($5-ish). Not required, but convenient if you ever need a replacement.
Good news: zero sales tax to bring your vehicle into Wyoming from another state.
The Formula
Wyoming calculates your annual registration based on two things: original MSRP and vehicle weight. Not what you paid. Not current value. The sticker price when it was new.
The state applies a depreciation schedule to the MSRP: Brand new = 60%, 1-2 years = 50%, 2-3 years = 40%, 3-4 years = 30%, 4-5 years = 20%, and 5+ years = 15% (floor). It never drops below 15%.
Each county has its own percentage fee. Park County is 3%. This varies across the state, so call your county treasurer if you're elsewhere.
Then add a flat state weight fee based on vehicle class: small truck/car ~$35, half-ton $50, three-quarter ton ~$70, one-ton dually $90.
Real Example: 2016 F-150
- Original MSRP: $40,345
- Age: 5+ years = 15% depreciation rate
- Depreciated value: $40,345 x 0.15 = $6,052
- Park County fee (3%): $6,052 x 0.03 = $181.56
- State weight fee (half-ton): $50
- Total annual registration: $231.56
A brand-new version of the same truck would be: $40,345 x 0.60 x 0.03 + $50 = $776.21/year. That depreciation schedule matters.
The Silver Linings
- No emissions testing. None. Drive whatever you want.
- No vehicle inspection. Nothing.
- No sales tax on imported vehicles. Bring your car from any state, pay zero.
