A Fuel Tax Credit Calculator helps businesses and individuals estimate the amount they can claim back on fuel taxes paid for eligible activities. In the U.S., the IRS allows fuel tax credits for off-highway business use, farming, and certain other exempt purposes.
How to Calculate Fuel Tax Credit:
The credit depends on:
- Fuel Type (Diesel, Gasoline, Biodiesel, etc.)
- Usage (Off-road, farming, public transit, etc.)
- Current IRS Fuel Tax Rates
2024 Federal Fuel Tax Rates (U.S.):
| Fuel Type | Tax Rate (per gallon) |
|---|---|
| Gasoline | $0.184 |
| Diesel | $0.244 |
| Liquefied Petroleum Gas (LPG) | $0.183 |
| Compressed Natural Gas (CNG) | $0.183 per gallon equivalent |
| Biodiesel* | Varies (check IRS) |
*Biodiesel may qualify for additional credits.
Formula:
[
\text{Fuel Tax Credit} = \text{Gallons Used for Eligible Purposes} \times \text{Tax Rate}
]
Steps to Calculate:
- Determine Eligible Fuel Use (e.g., farming equipment, construction machinery).
- Track Gallons Consumed for those activities.
- Apply the Correct Tax Rate based on fuel type.
- Multiply Gallons by Rate to get your credit.
Example Calculation:
- Fuel Type: Diesel
- Gallons Used Off-Road: 1,000
- Tax Rate: $0.244/gallon
[
\text{Credit} = 1{,}000 \times 0.244 = \$244

What is a Fuel Tax Credit?
A fuel tax credit is a refund or reduction in taxes paid on fuel used for specific off-road or exempt purposes. The IRS allows businesses and individuals to claim back federal excise taxes on fuels like:
- Diesel
- Gasoline
- Biodiesel
- Compressed Natural Gas (CNG)
- Liquefied Petroleum Gas (LPG)
These credits apply when fuel is used for:
✔ Farming equipment (tractors, combines)
✔ Construction machinery (excavators, bulldozers)
✔ Marine vessels (boats, barges)
✔ Railroad and aviation (in some cases)
✔ Government and nonprofit operations
Note: On-road fuel use (e.g., commercial trucks on highways) does NOT qualify because those taxes fund road maintenance.
Who Qualifies for Fuel Tax Credits?
Not everyone can claim fuel tax credits. Here’s who’s eligible:
1. Farmers & Agricultural Businesses
- Fuel for tractors, irrigation pumps, and other off-road farm equipment.
2. Construction Companies
- Diesel used in bulldozers, cranes, and generators at job sites.
3. Mining & Logging Operations
- Fuel for off-road heavy machinery.
4. Government & Public Transit Agencies
- Municipal buses, emergency vehicles, and other exempt uses.
5. Marine & Railroad Industries
- Fuel for boats, ferries, and locomotives (some restrictions apply).
⚠️ Important: Personal vehicle use does NOT qualify.
How Fuel Tax Credit Calculators Work
A Fuel Tax Credit Calculator helps estimate your refund by considering:
- Fuel Type (diesel, gasoline, biodiesel, etc.)
- Gallons Used for Eligible Activities
- Current IRS Fuel Tax Rates
Formula:
[
\text{Fuel Tax Credit} = \text{Gallons Used} \times \text{IRS Tax Rate per Gallon}
]
Example Calculation:
- Fuel: Diesel
- Gallons Used Off-Road: 5,000
- IRS Tax Rate (2024): $0.244/gallon
[
5{,}000 \times \$0.244 = \$1{,}220 \text{ credit}
]
Step-by-Step Fuel Tax Credit Calculation
Step 1: Track Eligible Fuel Usage
- Keep detailed records of fuel purchases.
- Separate on-road (non-eligible) and off-road (eligible) usage.
Step 2: Identify the Correct Tax Rate
| Fuel Type | 2024 IRS Tax Rate (per gallon) |
|---|---|
| Gasoline | $0.184 |
| Diesel | $0.244 |
| Biodiesel | Varies (check IRS) |
| LPG / CNG | $0.183 |
Step 3: Multiply Gallons by Tax Rate
- If you used 3,000 gallons of off-road diesel:
[
3{,}000 \times \$0.244 = \$732 \text{ credit}
]
Step 4: File the Correct IRS Form
- Form 4136 (for general claims)
- Form 8849 (for refunds)
How to Claim Your Fuel Tax Credit
- Keep Accurate Records (receipts, logs, invoices).
