What is the US gas guzzler tax?
The US gas guzzler tax is a federal excise tax generally associated with the sale of certain passenger automobiles that do not meet specified fuel economy standards. In practice, the tax is commonly tied to fuel economy values determined under EPA rules.
Because the rules can depend on vehicle type and how the vehicle is placed into the market (for example, manufactured vs. imported), many businesses confirm their liability using official guidance before filing.
For official references, review:
- IRS Form 720 (Quarterly Federal Excise Tax Return)
- IRS instructions for Form 720

How eFileExcise720 supports gas guzzler tax filing (step-by-step)
Our process is designed to be clear and guided, even if you do not file excise taxes every day.
1) Create your free account
Start by creating an account on eFileExcise720. There is no software to install.
2) Select Form 720 and enter your quarter details
Choose the correct tax period, then follow the prompts to enter the information needed for your gas guzzler tax filing and any other applicable excise tax categories.
3) Review, validate, and submit your return
Before submission, review your entries for accuracy. Once you transmit, you can keep your filing records in one place for easier reference later.
Filing deadlines (Form 720)
Form 720 is generally filed quarterly. Many filers follow these common due dates:
- Q1: due April 30
- Q2: due July 31
- Q3: due October 31
- Q4: due January 31
If a due date lands on a weekend or legal holiday, the deadline typically shifts to the next business day. Also, some excise taxes have deposit rules during the quarter depending on liability.
Because deadlines and payment rules can vary based on your facts, confirm the requirements in the IRS Form 720 instructions.
Gas tax and gas guzzler tax: don’t mix them up
Many people search “gas tax” and land on gas guzzler topics, but these are not the same.
- Fuel excise taxes (often called “gas tax”) are typically tied to the sale, removal, or use of taxable fuels.
- Gas guzzler tax is generally tied to the fuel economy rating of certain passenger automobiles.
Both can be reported on Form 720, but they apply to different activities and business profiles. eFileExcise720 supports all Form 720 categories, so you can handle multiple excise items in one return when applicable.
Gas guzzler tax credit and refund claims (when Form 8849 may apply)
Some businesses look for a “gas guzzler tax credit” when what they really need is a credit or refund process for excise taxes in specific situations.
In general:
- Credits may be claimed on Form 720 in certain circumstances.
- Refund claims are commonly made on Form 8849, depending on the type of excise tax and the reason for the claim.
Eligibility rules can be very specific, and not every excise tax has the same credit or refund pathway. If you believe you have an overpayment or a valid claim, review IRS guidance or consult your tax professional, then use eFileExcise720 to prepare the appropriate form.
Amending a gas guzzler excise tax filing (Form 720-X)
If you discover an error after filing, you may need to amend. eFileExcise720 supports Form 720 amendments (720-X) so you can correct prior reporting without rebuilding everything from scratch.
Common reasons businesses amend include:
- Correcting taxable quantities or tax calculations
- Fixing misapplied categories
- Updating previously reported amounts after receiving corrected source data
PCORI Form filing (PCORI fee on Form 720)
Many filers refer to the PCORI fee filing as the “PCORI Form.” The PCORI fee is reported on Form 720 (often as an annual filing tied to a specific due date).
If your organization is responsible for PCORI and also files quarterly excise returns, it helps to use one portal that supports both.
To confirm PCORI obligations, review the IRS PCORI information and current fee guidance:
