Washington fleet operators just got access to one of the largest state-level zero-emission vehicle voucher programs in the country. The funding is live, the portal is open, and most commercial fleet managers operating in the state have not started their application.
That gap is where incentive funding gets left on the table. The Washington Zero-Emission Incentive Program (WAZIP) offers instant point-of-sale discounts on medium and heavy-duty zero-emission vehicles and equipment for businesses operating in Washington state, with more than $112 million available through fiscal year 2026-27.
Key Takeaways
- WAZIP offers point-of-sale voucher discounts of up to $200,000 per vehicle on Class 2b through Class 8 zero-emission trucks and equipment for businesses operating in Washington.
- The program is administered by WSDOT and managed by CALSTART, with more than $112 million in active funding for FY25-27, sourced from Washington’s Climate Commitment Act.
- Vouchers are applied at the point of sale through approved dealers, so the discount happens at the transaction rather than through a delayed reimbursement.
- WAZIP can be stacked with other eligible incentives up to 90 percent of total vehicle cost, and it works for mixed fleets that combine diesel and zero-emission vehicles.
- Funding is divided into defined pools ($82 million on-road, $20 million off-road) that close when consumed, so operators who prepare procurement early are best positioned.
Quick Answer
WAZIP is Washington’s state-funded voucher program offering point-of-sale discounts of up to $200,000 per vehicle on Class 2b through Class 8 zero-emission trucks and equipment. Administered by the Washington State Department of Transportation (WSDOT) and managed by CALSTART, the program has over $112 million in active funding for FY25-27 and can be stacked with other eligible incentives to reduce acquisition cost by up to 90 percent.
What Is WAZIP and How Is It Funded?
WAZIP is administered by the Washington State Department of Transportation and managed by CALSTART. Funding comes from Washington’s Climate Commitment Act, the state’s cap-and-invest program. The program is designed to lower the upfront acquisition cost of zero-emission on-road vehicles and off-road equipment for commercial operators across Washington, a direct response to the kind of fleet electrification economics that make early adoption challenging without support.
The program works through an approved dealer network. Purchasers select an eligible vehicle from the WAZIP catalog, work with a participating dealer, and receive the voucher discount at the point of sale. There is no post-purchase rebate application or reimbursement delay, because the price reduction happens at the transaction.
That structure eliminates the cash flow gap that makes many incentive programs difficult for smaller fleet operators to use, and it pairs well with a disciplined fleet replacement strategy that prioritizes the vehicles where electrification pays back fastest. For broader context on how state programs compare, the AFDC state laws and incentives database tracks similar voucher structures nationwide.
What Voucher Amounts Are Available by Vehicle Class?
According to the WAZIP funding page, base and enhanced voucher amounts for on-road vehicles are structured by vehicle class:
- Class 2b (8,501-10,000 lbs GVWR): $7,500 base / $10,000 enhanced
- Class 3 (10,001-14,000 lbs): $45,000 base / $50,000 enhanced
- Class 4 (14,001-16,000 lbs): $60,000 base / $70,000 enhanced
- Class 5 (16,001-19,500 lbs): $80,000 base / $90,000 enhanced
- Class 6 (19,501-26,000 lbs): $90,000 base / $100,000 enhanced
- Class 7 (26,001-33,000 lbs): $135,000 base / $150,000 enhanced
- Class 8 (33,001+ lbs): $175,000 base / $200,000 enhanced
Enhanced vouchers are available to Emerging Businesses with gross annual receipts of $3 million or less, and Rising Businesses with receipts of $10 million or less. For fleet operators in those categories, the enhanced tier can add $5,000 to $25,000 per vehicle over the base amount. WAZIP also includes infrastructure rebates of up to $30,000 per charging station for equipment rated at 351 kilowatts or greater, which provides partial offset for the charging infrastructure costs that typically run parallel to vehicle acquisition.
How Does WAZIP Work for Small and Mid-Size Fleet Operators?
The enhanced voucher structure makes WAZIP especially valuable for small and mid-size fleet operators who are adding their first electric or zero-emission vehicles to an existing fleet. The point-of-sale mechanism means the financial benefit arrives at the moment of highest capital pressure, not months later, and the real cost savings show up in the actual transaction price. Pairing those savings with the right fleet financing structure can further reduce the net cost of acquisition.
Operators with mixed fleets that include a combination of diesel and zero-emission vehicles are eligible under WAZIP. The program does not require a fully electrified fleet, so it is built for businesses at any stage of integrating cleaner vehicles into their existing fleet operations. Used vehicles qualify for 50 percent of the base voucher amount, and converted or remanufactured vehicles qualify for 80 percent of the base amount, expanding the eligible vehicle pool beyond new purchases. Understanding how these vouchers affect long-term economics is easier when you start from a clear fleet electrification TCO model.
Can WAZIP Be Stacked With Other Incentive Programs?
WAZIP can be combined with other eligible incentive sources. The combined total of all incentives cannot exceed 90 percent of the total vehicle or equipment cost, excluding taxes and fees. WAZIP is applied last in the stack, covering remaining costs up to the voucher maximum. For detailed stacking guidance, the WAZIP Implementation Manual outlines program rules for combining funding sources, and the AFDC vehicle cost calculator can help model the net effect on total cost.
For Washington fleet operators, this stacking capability is material. Combining WAZIP with utility rebates from Puget Sound Energy, Snohomish County PUD, or other participating utilities can close a significant portion of the cost gap between diesel and zero-emission alternatives. Research from the National Renewable Energy Laboratory consistently shows that layered incentives are what move fleet electrification from theoretical to practical. Operators serving routes across state lines may also track parallel mandates such as California’s Advanced Clean Fleets program, which shapes how regional zero-emission demand is developing.
This is not a program where one incentive replaces another. It is a program designed to be layered on top of every other eligible funding source your fleet can access, which is why an EV-first fleet management approach treats incentive stacking as a core part of procurement.
How Do You Apply and What Should You Do Before Funding Closes?
The WAZIP Voucher Processing Center portal opened April 29, 2026 for approved dealers. To access vouchers, fleet purchasers work through a WAZIP-approved dealer who submits the application on their behalf, and the approved dealer list is available on the WAZIP website.
Funding is divided into set allocations: $82 million for on-road vehicles and $20 million for off-road equipment. These allocations apply through October 2026. Programs with defined funding pools close when that funding is consumed, so operators who identify eligible vehicles, connect with approved dealers, and have procurement agreements in place are best positioned to move when windows are open. Fleets weighing acquisition models alongside these vouchers should also review the tradeoffs in our lease versus own TCO breakdown.
