How Wyoming Registration Fees Are Calculated
In Wyoming, vehicle registration fees are divided into two distinct parts: a State Fee and a County Fee. While the state fee is a fixed amount based on the weight of the vehicle, the county fee is an "Ad Valorem" tax (based on value).
1. The County Fee (The Ad Valorem Tax)
The county fee is calculated using the vehicle's original factory price (MSRP), not the price you paid or the current market value. The formula used by Wyoming Treasurers is:
(Factory Price × 0.60) × Year Multiplier = County Fee
| Year of Service | Assessment Rate |
|---|---|
| 1st Year | 3.0% (0.030) |
| 2nd Year | 2.5% (0.025) |
| 3rd Year | 2.0% (0.020) |
| 4th Year | 1.5% (0.015) |
| 5th Year | 1.0% (0.010) |
| 6th Year + | 0.5% (0.005) |
2. The State Fee
The state fee is a flat rate determined by the vehicle's unladen weight and type. Most passenger cars and light-duty SUVs/trucks fall into the $30 category. Heavier commercial vehicles or large trucks pay more according to a tiered weight scale.
Example Calculation
If you own a 3-year-old vehicle with a factory MSRP of $30,000:
- County Fee: ($30,000 × 60%) × 2.0% = $360.00
- State Fee: $30.00 (Standard Passenger)
- Estimated Total: $390.00
Frequently Asked Questions
Do I need to pay sales tax?
Yes, if you just purchased the vehicle, you must pay state sales tax (usually 4% state + 1-2% local) before you can register it. This calculator only estimates the recurring annual registration fee.
What is the "Factory Price"?
This is the Manufacturer's Suggested Retail Price (MSRP) when the vehicle was new. It does not decrease as the car gets older; rather, the "Year Multiplier" percentage decreases to account for depreciation.
Are there additional costs?
Some counties may charge a small administrative fee, and specialty license plates (like University of Wyoming or Wildlife plates) carry additional annual costs.
