U.S. Individual Income Tax Return Forms

Note: The draft you are looking for begins on the next page.

Caution: DRAFT—NOT FOR FILING

This is an early release draft of an IRS tax form, instructions, or publication,
which the IRS is providing for your information. Do not file draft forms and do
not rely on draft forms, instructions, and pubs for filing. We incorporate all
significant changes to forms posted with this coversheet. However, unexpected
issues occasionally arise, or legislation is passed—in this case, we will post a
new draft of the form to alert users that changes were made to the previously
posted draft. Thus, there are never any changes to the last posted draft of a
form and the final revision of the form. Forms and instructions are subject to
OMB approval before they can be officially released, so we post drafts of them
until they are approved. Drafts of instructions and pubs usually have some
additional changes before their final release. Early release drafts are at
IRS.gov/DraftForms and remain there after the final release is posted at
IRS.gov/LatestForms. Also see IRS.gov/Forms.
Most forms and publications have a page on IRS.gov: IRS.gov/Form1040 for
Form 1040; IRS.gov/Pub501 for Pub. 501; IRS.gov/W4 for Form W-4; and
IRS.gov/ScheduleA for Schedule A (Form 1040), for example, and similarly for
other forms, pubs, and schedules for Form 1040. When typing in a link, type it
into the address bar of your browser, not a Search box on IRS.gov.
If you wish, you can submit comments to the IRS about draft or final forms,
instructions, or pubs at IRS.gov/FormsComments. Include “NTF” followed by the
form or pub number (for example, “NTF1040”, “NTFW4”, “NTF501”, etc.) in the
body of the message to route your message properly. We cannot respond to all
comments due to the high volume we receive and may not be able to consider
many suggestions until the subsequent revision of the product, but we will
review each “NTF” message. If you have comments on reducing paperwork and
respondent (filer) burden, with respect to draft or final forms, please respond to
the relevant information collection through the Federal Register process; for

Future Developments

Fuel Tax Credit (FTC) worksheet. To help you
determine if you're qualified to claim any fuel tax credit
(FTC) on Form 4136, you must attach the worksheet
provided in these instructions to your return with Form
4136. See Worksheet Fuel Tax Credit-1.

Notice 2024-37 sustainable aviation fuel (SAF) guidance. In December 2023 Notice 2024-06, sections 5 and
6, explained that the Greenhouse gases, Regulated
Emissions, and Energy use in Transportation (GREET)
Model methodology existing at that time didn't satisfy the
statutory requirements to calculate the emissions
reduction percentage under section 40B(e)(2), and that
the government would work to develop information on the
safe harbor available for the newly developed
40BSAF-GREET model along with a safe harbor and
related requirements for the USDA Climate Smart
Agriculture Pilot Program, Notice 2024-37, issued April
2024, provides the new model.
The section 40B SAF credit will expire for sales or
uses after 2024, but will become available under
CAUTION section 45Z, as the clean fuel production credit in
2025. See Notice 2024-49.

!

The credits for biodiesel mixtures, renewable diesel
mixtures, agri-biodiesel mixtures, alternative fuels, and
alternative fuel mixtures expire for fuels sold or used after
2024. Congress may take additional legislative action that
impacts these credits. Don't claim the credits for fuels sold
or used after 2024 unless they're extended. For the latest
information about developments related to Form 4136 and
its instructions, such as legislation enacted after they were
published, go to IRS.gov/Form4136.

Reminders
Removal of liquefied hydrogen from alternative fuel
credits. The section 6426(d) definition of alternative fuels

Purpose of Form

Use Form 4136 to claim the following.
• The biodiesel, agri-biodiesel, or renewable diesel
mixture credit.
• The alternative fuel credit.
• A credit for certain nontaxable uses (or sales) of fuel
during your income tax year.
• A credit for blending a diesel-water fuel emulsion.
• A credit for exporting dyed fuels or gasoline
blendstocks.
• Substainable aviation fuel (SAF) credit.

Attach Form 4136 and Worksheet Fuel Tax Credit-1 to
your tax return.

Instead of waiting to claim an annual credit on Form
4136, you may be able to file:
• Form 8849, Claim for Refund of Excise Taxes, to claim a
periodic refund; or
• Form 720, Quarterly Federal Excise Tax Return, to claim
a credit against your excise tax liability.
You can’t claim any amounts on Form 4136 that
you claimed on Form 8849, Form 8864, or Form
CAUTION 720, Schedule C. If you report a tax liability on
Form 720, you may be required to offset your tax liability
with any credits you claim before claiming a credit on Form
4136, or Form 8864, or a refund on Form 8849.

Form 4136 can’t be used by ultimate vendors to make
gasoline claims.
Partnerships. Partnerships (other than electing large
partnerships) can’t file this form. Instead, they must
include a statement on Schedule K-1 (Form 1065)
showing the allocation to each partner specifying the
number of gallons of each fuel used during the tax year,
the applicable credit per gallon, the nontaxable use or
sale, and any additional information required to be
submitted.
