Despite losing most of their state and federal incentives, electric vehicle owners in Washington state are still saving significant money compared to gas vehicle owners. The numbers show that EV drivers across the country save an average of $11,053 over 10 years. Washington state drivers save even more, cutting $18,055 in fuel costs over the same period.
Washington state EV owners save $18,055 in fuel costs over 10 years, even after losing most incentives.
The reason for the gap comes down to gas prices. Washington state has higher fuel costs than much of the country. That puts extra pressure on drivers who own conventional gas-powered vehicles. Those costs add up fast over time.
On average, gas vehicles typically cost around $350 per month for fuel and maintenance combined, with EVs often $200 less per month than their gas equivalent. That difference in monthly expenses is what drives the long-term savings for EV owners. Lower fuel and maintenance costs are the biggest factors.
Washington state had several programs that once helped people buy EVs. The state’s instant rebate program ran out of funds. A sales-tax exemption for most passenger EVs ended after July 31, 2025. Federal clean vehicle tax credits have largely phased out. So most of the big financial perks that once helped buyers are now gone.
Some incentives still exist, though they’re more limited. A sales and use tax exemption still applies to new EVs priced at $45,000 or less, covering up to $15,000 of the purchase. Used EVs under certain price thresholds may still qualify for exemptions up to $16,000. Utilities like Clark Public Utilities offer rebates up to $2,000 for qualifying low-income EV buyers. For lower-income households, energy costs can burden lower-income households at nearly 14% of income, making the long-term fuel savings from EVs especially meaningful.
Federal charger credits are also still available. Homeowners can claim up to $1,000 for installing a Level 2 charger at home, through June 30, 2026. Utilities across the state offer additional rebates for home chargers and discounted off-peak electricity rates for EV charging. Washington also has over 2,900 public charging stations statewide, giving EV drivers broad access to affordable charging beyond the home.
Hydrogen fuel-cell vehicles remain an exception in Washington’s incentive landscape, as they still qualify for a sales and use tax exemption through July 31, 2028, though limited fueling infrastructure makes them a practical option for only a small number of drivers.
Even without the bigger incentives, analysts say EV fuel savings still outweigh the lost credits. Dealer discounts and financing options are also helping to fill some of that gap.
