What is the Alternative Fuel Vehicle Credit?
The alternative fuel vehicle credit under IRC Section 30B provides tax credits for vehicles that run on qualified alternative fuels, including compressed natural gas (CNG), liquefied natural gas (LNG), liquefied petroleum gas (propane), and hydrogen. Unlike the Clean Vehicle Credit, this credit has no income limits and can provide substantial benefits for commercial vehicles.
Credit Amounts by Vehicle Type and Weight
The credit varies dramatically based on vehicle weight and type:
Example: Natural Gas Delivery Truck
Let's say your business purchases a CNG delivery truck weighing 18,000 lbs for $85,000:
1. Base credit: $10,000 (14,001-26,000 lb category)
2. Fuel economy credit: Up to $5,000 (based on EPA fuel economy rating)
3. Total credit: Up to $15,000
4. Tax impact: Reduces your business tax liability by $15,000
5. Additional benefit: Full Section 179 deduction still available on remaining cost
Fuel Cell Vehicle Credit (Higher Amounts)
Fuel cell vehicles qualify for even higher credits:
Business Advantages Over Personal Use
Business owners get significant advantages with this credit:
No income limitations: Unlike the Clean Vehicle Credit, there are no AGI restrictions
Stackable with business deductions: You can claim both the credit and depreciation/Section 179

Immediate benefit: Credit reduces current year tax liability dollar-for-dollar
Alternative Fuel Infrastructure Credit
Businesses can also claim a 30% credit (up to $30,000) for installing alternative fuel refueling equipment:
