Wyoming electric vehicle owners face a layered set of charges that changed significantly in 2026. All-electric vehicles now pay a $100 annual decal fee on top of standard registration, down from the former $200 charge. Plug-in hybrids pay $50 per year for the first time under new law. Starting July 1, 2026, electricity sold to charge EVs at public stations is taxed at 3.5 cents per kilowatt-hour. Beyond those EV-specific charges, every vehicle owner pays a low flat state registration fee ($30 for passenger cars), a county ad valorem tax based on factory price and vehicle age, a $15 title fee, and sales tax of 4% plus local add-ons on purchase. Wyoming electricity remains affordable at roughly 10 to 12 cents per kilowatt-hour for residential customers. Federal EV purchase credits no longer apply to 2026 acquisitions, though a home charger credit may still apply for equipment installed by June 30, 2026. This guide explains every fee, tax, rate, and calculation in plain English so you can estimate what it really costs to register and own an EV in Wyoming.
Wyoming is a wide-open, low-population state where driving distances are long and fuel costs matter. The state has historically funded highways through gasoline and diesel taxes paid at the pump. Electric vehicles bypass that mechanism, which led Wyoming to impose special registration fees on EVs starting in 2019. The original $200 annual decal fee was among the highest in the country. House Bill 0145 in 2026 cut that charge to $100 for battery-electric vehicles and created a new $50 fee for plug-in hybrids, effective July 1, 2026.
At the same time, Wyoming expanded how it taxes electricity used as vehicle fuel. Beginning October 2025, the Wyoming Department of Transportation began collecting motor fuel tax at public EV charging stations using a gasoline-gallon equivalent formula. HB0145 replaced that approach with a clearer license tax of 3.5 cents per kilowatt-hour on electricity dispensed for vehicle charging at commercial stations, starting July 1, 2026. Home charging is not subject to this per-kilowatt-hour fuel tax, though you still pay your normal utility rate.
Registration costs in Wyoming combine a modest state flat fee with a county property-style tax that can be substantial on new vehicles. A $50,000 car in its first registration year owes county tax of 3% times 60% of factory price, or $900, plus $30 state fee, plus $100 EV decal. That $1,030 in annual registration alone exceeds what many states charge for a new EV. Sales tax at purchase adds another 4% statewide plus typically 1 to 2% local, so Cheyenne buyers might pay 6% total on a new vehicle.
On the positive side, Wyoming electricity is cheap. Rocky Mountain Power residential customers pay about 11.5 cents per kilowatt-hour on Schedule 2, and Black Hills Energy customers pay about 10.8 cents. Federal new and used EV purchase credits ended for vehicles acquired after September 30, 2025, so 2026 buyers should not count on a $7,500 federal discount unless law changes. Wyoming offers no state EV purchase rebate. Anyone building a Wyoming EV cost calculator needs these registration tiers, county depreciation factors, charging taxes, utility rates, and purchase tax rules together. That is what this guide provides.
Wyoming State Registration and EV Decal Fees
Wyoming Statutes Title 31 govern vehicle registration. The state portion for most personal vehicles is a flat fee, separate from county charges and EV decals.
Standard state registration fees
| Vehicle class | Annual state fee | Statute reference |
|---|---|---|
| Passenger car | $30 | W.S. §31-3-101(a)(ii)(A) |
| Motorcycle, autocycle, multipurpose vehicle | $25 | W.S. §31-3-101(a)(ii)(D) |
| House trailer (≤ 1,000 lb) | $5 | W.S. §31-3-101(a)(ii)(E) |
| House trailer (1,001–3,500 lb) | $30 | Weight tier schedule |
| House trailer (3,501–4,500 lb) | $40 | Weight tier schedule |
| House trailer (4,501–5,500 lb) | $50 | Weight tier schedule |
| House trailer (5,501–6,000 lb) | $70 | Weight tier schedule |
| House trailer (≥ 6,001 lb) | $90 | Weight tier schedule |
| Commercial (≤ 26,000 lb GVW) | $198 | W.S. §31-18-401 |
| Commercial (80,001+ lb) | $948.75+ | Increases per weight bracket |
Commercial trucks and heavy vehicles follow weight-based schedules under W.S. Section 31-18-401, with fees rising in roughly $16.50 increments per 2,000-pound bracket. Electric commercial trucks use the same weight tables as diesel trucks. Overweight permits and axle fees under W.S. Sections 31-18-201 and 31-18-202 apply separately when vehicles exceed legal limits.
EV decal fees (effective July 1, 2026)
Under W.S. Section 31-3-102, Wyoming charges an annual decal fee on alternative-fuel vehicles, displayed through the bucking horse and rider emblem program:
- All-electric vehicle (BEV): $100 per year (reduced from $200 under prior law)
- Plug-in hybrid (PHEV): $50 per year (new fee under HB0145)
These decals are charged on top of the standard state registration fee and county ad valorem tax. Gasoline and conventional hybrid vehicles without plug-in capability pay no EV decal. Electric motorcycles still require the $100 EV decal plus the $25 motorcycle registration fee.
First-year proration
When you register a vehicle mid-year, Wyoming prorates registration fees by months remaining in the registration period. Multiply the full annual state fee, county tax, and EV decal by (months remaining ÷ 12). Registering in July with six months left yields roughly half the annual total.
Example 1: New Passenger BEV (Full Year, Year 1)
Scenario: $30,000 new compact EV; first registration year; registered January.
State registration fee: $30.00 EV decal (all-electric): $100.00 County tax (see next section): $540.00 ────────────────────────────────────────── Total annual registration: $670.00
Gasoline passenger car with same county tax would pay $570 (no $100 decal).
Example 2: PHEV Registered Mid-Year (July)
Scenario: $35,000 plug-in hybrid; six months remaining in registration year.
Full-year total (est.): State $30 + PHEV $50 + County $630 = $710 Proration factor: 6/12 = 50% Prorated registration: $355.00 Title fee (one-time): $15.00
Example 3: Electric Motorcycle
State motorcycle fee: $25.00 EV decal (all-electric): $100.00 County tax (varies by value): + county amount ────────────────────────────────────────── EV premium over gas motorcycle: +$100/yr
Important: HB0145 took effect July 1, 2026. Battery-electric decal fees dropped from $200 to $100. Plug-in hybrids now owe $50 annually. Confirm current amounts with your county treasurer at renewal.

County Ad Valorem Registration Tax
Wyoming counties collect an annual registration tax equal to 3% of (depreciation factor × factory price) under W.S. Section 31-3-101(a)(i). Factory price means the original manufacturer suggested retail price plus factory-installed options, not necessarily what you paid on a used vehicle. For used vehicles, the county still applies the original factory price in the formula.
Depreciation factors by vehicle age
| Registration year of vehicle | Factor (% of factory price) |
|---|---|
| Year 1 | 60% |
| Year 2 | 50% |
| Year 3 | 40% |
| Year 4 | 30% |
| Year 5 | 20% |
| Year 6 and later | 15% |
A $5 minimum county fee applies when the calculated amount falls below five dollars.
County tax formula:
County tax = 0.03 × (Factor × Factory price)
Example 1: Year 1 Vehicle, $50,000 Factory Price
Taxable value: 60% × $50,000 = $30,000 County tax: 3% × $30,000 = $900.00
Example 2: Same Vehicle in Year 6
Taxable value: 15% × $50,000 = $7,500 County tax: 3% × $7,500 = $225.00
County registration drops sharply as the vehicle ages, even though the EV decal stays at $100 per year.

Electricity and Alternative-Fuel Taxes on EV Charging
Wyoming treats electricity as an alternative fuel for transportation purposes. How that fuel is taxed depends on where you charge.
Home and workplace charging
Electricity you use at home to charge your EV is not subject to the per-kilowatt-hour vehicle fuel license tax. You pay your normal utility energy rate plus any fixed monthly customer charge. Residential power in Wyoming is not subject to state sales tax in the same way as goods, though utilities may pass through various riders and distribution charges.
Public charging (from July 1, 2026)
HB0145 imposes a license tax of $0.035 per kilowatt-hour on electricity sold for vehicle charging at commercial stations. Sales of that charging electricity are exempt from Wyoming sales tax. At 33.56 kilowatt-hours per gasoline gallon equivalent, 3.5 cents per kWh equates to roughly $1.17 per GGE, compared with Wyoming’s gasoline fuel tax of 24 cents per gallon at the pump.
From October 2025 until the new law took full effect, WYDOT collected motor fuel tax at public chargers using a gallon-equivalent method at $0.24 per GGE. Calculators modeling 2026 should use the 3.5 cent per kWh rate for public charging energy subject to the license tax.
How charging mix affects your cost
If you drive 12,000 miles per year at 4 miles per kilowatt-hour, you consume 3,000 kWh annually. Charging 100% at home: no license tax, only utility cost. Charging 100% at public stations: 3,000 × $0.035 = $105 in license tax plus higher per-kWh station pricing (often 30 to 40 cents per kWh).
Example 1: All Home Charging (12,000 mi, 4 mi/kWh)
Annual kWh: 12,000 ÷ 4 = 3,000 kWh Utility cost at 11.5¢/kWh: 3,000 × $0.115 = $345.00 Alternative-fuel license tax: $0.00
Example 2: 30% Public / 70% Home (Same Driving)
Total kWh: 3,000 Home (70%): 2,100 × $0.115 = $241.50 Public energy (30%): 900 × $0.35 = $315.00 (est. station rate) License tax on public kWh: 900 × $0.035 = $31.50 ────────────────────────────────────────── Total annual charging cost: $588.00

Sales Tax, Title Fees, and Purchase Charges
Certificate of title
Wyoming charges a $15 certificate of title fee for new titles and duplicates under W.S. Section 31-3-102(a)(vii). This is a one-time charge at initial registration unless you replace a lost title.
Sales and use tax on vehicle purchases
Wyoming imposes a 4% state sales tax on motor vehicle purchases. Counties and some municipalities add local option tax, typically 1 to 2 additional percentage points. Cheyenne commonly totals around 6% combined. Use tax applies similarly when you title an out-of-state purchase in Wyoming.
Electricity sold specifically as vehicle fuel at commercial chargers is exempt from sales tax under the 2026 framework, but vehicle purchases, parts, and most other goods follow normal sales tax rules.
Example 1: $30,000 EV Purchase in Cheyenne (6% Combined)
Purchase price: $30,000.00 Sales/use tax (6%): $1,800.00 Title fee: $15.00 First-year registration: $670.00 ────────────────────────────────────────── Upfront beyond vehicle: $2,485.00 (before energy costs; no federal purchase credit in 2026)
Example 2: $50,000 EV in Lower-Tax County (5% Combined)
Sales tax (5%): $2,500.00 Title: $15.00 Registration (Yr 1): $1,030.00 ────────────────────────────────────────── Upfront charges: $3,545.00
Federal incentives in 2026
- New EV credit (IRC §30D): up to $7,500 — generally unavailable for vehicles acquired after September 30, 2025
- Used EV credit (IRC §25E): up to $4,000 — same acquisition cutoff
- Home charger credit (IRC §30C): 30% up to $1,000 for qualifying residential equipment placed in service on or before June 30, 2026
Wyoming offers no state tax credit or rebate for EV purchases.

Wyoming Utility Rates and Charging Costs
Wyoming residential electricity costs less than the national average, which helps offset registration and public charging taxes for drivers who plug in at home.
Major utility schedules (2026)
| Utility / rate | Energy rate | Fixed monthly charge | Notes |
|---|---|---|---|
| Rocky Mountain Power Schedule 2 (flat) | 11.515¢/kWh | $23.00 | Residential single-phase |
| Rocky Mountain Power TOU off-peak | 9.210¢/kWh | $23.00 | Overnight and mid-day windows |
| Rocky Mountain Power TOU on-peak | 15.432¢/kWh | $23.00 | 7–9 a.m. and 5–11 p.m. |
| Black Hills Energy Wyoming residential | 10.787¢/kWh | $15.50 | Energy charge plus customer charge |
For calculator defaults, use 11 cents per kilowatt-hour as a statewide average unless the user selects a specific utility or time-of-use plan. Public DC fast charging typically runs 30 to 40 cents per kilowatt-hour before the 3.5 cent license tax.
Energy cost per mile
A compact EV achieving 4 miles per kilowatt-hour at 11.5 cents per kWh costs about 2.9 cents per mile for energy. A gasoline car at 30 mpg and $3.50 per gallon costs about 11.7 cents per mile. The EV decal adds roughly 0.8 cents per mile at 12,000 annual miles ($100 ÷ 12,000).
Example 1: Rocky Mountain Power Flat Rate (12,000 mi/yr)
kWh: 12,000 ÷ 4 = 3,000 Energy: 3,000 × $0.11515 = $345.45 Fixed charge (12 mo): 12 × $23 = $276.00 (Allocate fixed charge to whole home or ignore for marginal EV cost) Marginal EV energy only: ~$345/yr
Example 2: TOU Off-Peak Charging (80% off-peak)
Off-peak (80%): 2,400 × $0.0921 = $221.04 On-peak (20%): 600 × $0.1543 = $92.58 Blended energy cost: $313.62/yr (saves ~$32 vs. flat rate on energy portion)

How the Wyoming EV Cost Calculator Works
A Wyoming total cost of ownership calculator combines state and county registration, EV decal fees, sales tax at purchase, energy costs, public charging license tax, and optional federal charger credits. Follow these steps.
Step 1: Identify vehicle class and fuel type
Choose passenger car ($30 state fee), motorcycle ($25), trailer weight tier, or commercial GVW bracket. Add $100 EV decal for battery-electric or $50 for plug-in hybrid.
Step 2: Calculate county ad valorem tax
- Look up factory price (MSRP plus factory options)
- Apply depreciation factor for vehicle registration year (60% year 1 down to 15% year 6+)
- County tax = 3% × (factor × factory price), minimum $5
- Prorate if mid-year first registration: multiply by months remaining ÷ 12
Step 3: Add purchase charges (year one only)
Sales tax = Purchase price × (State + local rate) Title fee = $15
Step 4: Estimate annual energy cost
kWh per year = Annual miles ÷ miles per kWh Home cost = kWh home portion × residential $/kWh Public energy cost = kWh public portion × station $/kWh License tax = kWh at public commercial chargers × $0.035
Step 5: Multi-year totals
Repeat registration each year with updated depreciation factor for county tax. Sales tax applies only at purchase. EV decal remains $100 or $50 every year. Show year-by-year breakdown because county tax declines while decal fee stays constant.

Legislative Timeline and Policy Notes
- July 2019: Wyoming establishes $200 annual EV decal fee
- October 2025: WYDOT begins collecting motor fuel tax at public EV chargers ($0.24 per gasoline gallon equivalent)
- January 2026: HB0145 passes, reducing BEV decal to $100, adding $50 PHEV decal, imposing $0.035/kWh charging license tax, exempting charging electricity from sales tax
- July 1, 2026: New decal fees and kWh license tax take effect
Watch future legislative sessions for further EV fee adjustments. Wyoming’s combination of county ad valorem tax and EV decals can make registration costly on new vehicles even after the decal fee reduction.
Common Questions
How much is the Wyoming EV fee in 2026?
Battery-electric vehicles pay a $100 annual decal fee plus standard registration. Plug-in hybrids pay $50. Both are in addition to state ($30) and county taxes.
Did Wyoming lower the EV fee?
Yes. HB0145 cut the all-electric decal from $200 to $100 effective July 1, 2026.
Is home EV charging taxed in Wyoming?
Home charging is not subject to the 3.5 cent per kWh alternative-fuel license tax. You pay normal utility rates. Public commercial charging is taxed at $0.035 per kWh.
What is the county registration tax?
Counties charge 3% of a depreciation-adjusted factory price: 60% of MSRP in year one, declining to 15% by year six and beyond.
Does Wyoming have a state EV rebate?
No. Federal purchase credits also generally do not apply to 2026 acquisitions after the September 2025 cutoff.
Can I get a federal charger tax credit?
IRC Section 30C may provide 30% up to $1,000 for qualifying home charger equipment placed in service on or before June 30, 2026.
Do electric motorcycles pay the EV decal?
Yes. Electric motorcycles pay the $100 all-electric decal plus the $25 motorcycle registration fee.
What if I register mid-year?
Registration fees prorate by months remaining in the registration period.
Edge Cases
Leased vehicles: The leasing company typically holds title and registers the vehicle. Registration and decal fees still apply; sales tax treatment may flow through lease payments rather than a separate titling charge.
Out-of-state registration: Wyoming fees do not apply if the vehicle is titled elsewhere. Wyoming residents must register in Wyoming to use Wyoming plates.
Converted vehicles: A gasoline-to-electric conversion re-titled as all-electric owes the $100 EV decal. County tax still uses the original factory price.
Commercial EVs: Electric trucks follow commercial weight fee schedules under W.S. Section 31-18-401 plus the EV decal where applicable.
Where the Numbers Come From
Registration and decal fees come from Wyoming Statutes Sections 31-3-101 and 31-3-102 and HB0145 (2026). County tax formulas follow Section 31-3-101(a)(i). Sales tax rates come from Title 39 and Department of Revenue guidance. Alternative-fuel charging tax rules follow HB0145 and WYDOT implementation notices. Utility rates come from Rocky Mountain Power and Black Hills Energy published tariffs. Federal credit expiration follows IRS guidance on IRC Sections 30D, 25E, and 30C.

Key Takeaways for Wyoming EV Owners
Wyoming EV owners pay a $100 annual decal fee (battery-electric) or $50 (plug-in hybrid) on top of a $30 state registration fee and a county ad valorem tax that can reach $900 or more on a new $50,000 vehicle in year one. Purchase costs include 4% state sales tax plus local add-ons and a $15 title fee. Public charging faces a new 3.5 cent per kilowatt-hour license tax from July 2026; home charging does not.
Cheap electricity helps. At roughly 11 cents per kilowatt-hour, many EVs cost under 3 cents per mile for energy versus 12 cents or more for gasoline. County tax drops each year as depreciation factors decline, but the EV decal stays fixed. Federal purchase credits generally do not apply to 2026 buys; plan around state and local costs only.
Model your scenario with actual county sales tax rate, factory price, charging mix, and registration date. Home charging avoids the kWh license tax and keeps operating cost low. Confirm all fees with your county treasurer and the Wyoming Department of Transportation before you buy.
