What Is Section 45W?

Section 45W of the Internal Revenue Code, enacted by the Inflation Reduction Act of 2022 (Public Law 117-169), creates a tax credit for businesses that purchase new qualified commercial clean vehicles. Unlike the consumer-facing Section 30D credit, Section 45W is exclusively for vehicles placed in service in a trade or business.

For heavy-duty commercial operators — particularly SMB yard and terminal truck fleets — this is the single most impactful financial tool available for fleet electrification, offering up to $40,000 per qualifying vehicle.

The credit applies to tax years beginning after December 31, 2022 through December 31, 2032.

Eligibility Requirements

The Vehicle Must Be…

  • New — not previously placed in service or leased by any taxpayer
  • Acquired for use in a trade or business (not personal use)
  • Manufactured by a qualified manufacturer registered with the IRS
  • A motor vehicle with ≥4 wheels treated as a motor vehicle for purposes of Title II of the Clean Air Act
  • Propelled to a significant extent by an electric motor drawing power from a battery with ≥15 kWh capacity (vehicles ≥14,000 lbs) or ≥7 kWh (vehicles <14,000 lbs)

Disqualifying Factors

  • Vehicle previously placed in service by any taxpayer
  • Manufacturer not registered as a Qualified Manufacturer (QM) with the IRS
  • Vehicle used for personal rather than business purposes
  • Battery capacity below minimum threshold for the applicable weight class
  • Credit claimed on the same vehicle under Section 30D

How the Credit Is Calculated

The 45W credit is equal to the lesser of:

A

Percentage of Vehicle Cost

  • 30% of cost for fully electric (BEV) or fuel cell vehicles
  • 15% of cost for plug-in hybrid vehicles
B

Incremental Cost

The difference in purchase price between the qualifying clean vehicle and a comparable conventionally fueled vehicle of similar size and use.

This is a critical calculation — and where most operators make documentation errors.

Credit Cap by Vehicle Weight

Gross Vehicle Weight Rating (GVWR) Maximum Credit Min Battery Capacity Typical Vehicle Class
Under 14,000 lbs $7,500 ≥ 7 kWh Class 1–3 (cargo vans, pickup trucks)
14,000 lbs and over $40,000 ≥ 15 kWh Class 4–8 (medium and heavy duty, terminal trucks)

The Critical "Incremental Cost" Analysis

The IRS requires taxpayers to document the incremental cost — the price premium of the EV over a comparable conventionally fueled vehicle. Getting this wrong is the most common source of credit disqualification or audit risk. Key considerations:

Identifying a "Comparable" Vehicle

The comparable vehicle must have similar size, use, and payload capacity. The IRS does not require an exact match, but the comparison must be reasonable and documented.

Documentation Required

Retain dealer quotes or MSRP documentation for both the EV and the comparable ICE vehicle at the time of purchase. IRS Notice 2024-5 and related guidance provide additional clarity on documentation standards.

Interaction with Incentive Stacking

State incentives and manufacturer rebates applied at the point of sale may reduce the vehicle's basis and therefore affect the incremental cost calculation. This must be accounted for carefully.

How to Claim the Credit

1

Verify Manufacturer Registration

Confirm the vehicle manufacturer is registered as a Qualified Manufacturer (QM) with the IRS and has submitted a periodic report for the specific vehicle. Check the IRS QM list before purchase.

2

Obtain the VIN and QM Certificate

The manufacturer must provide documentation that the vehicle meets the qualifications. Retain the Vehicle Identification Number (VIN), purchase agreement, and QM confirmation.

3

Document the Incremental Cost

Prepare a written analysis comparing the qualifying EV to a comparable ICE vehicle, with supporting price documentation. This is the most audit-sensitive component.

4

File Form 8936 / 8936-A

Complete IRS Form 8936 (Schedule A for business use) or Form 8936-A and attach to your federal income tax return. The credit reduces your regular tax liability; unused credit may carry forward depending on your tax situation.

5

Consider the Transfer Election (2024+)

Starting in 2024, eligible businesses may elect to transfer the credit to the vehicle dealer at the point of sale, effectively receiving the credit as an upfront price reduction. This is subject to specific IRS procedures under Rev. Proc. 2023-33.
