Is Form 8849 Schedule 3 Still Available?

What Is Form 8849 and What was the Purpose of Schedule 3?

Form 8849, Claim for Refund of Excise Taxes, is an IRS form used in claiming a refund or credit of eligible federal excise taxes. Form 8849 comprises several schedules, each dealing with certain kinds of excise taxes claimed.
Form 8849 Schedule 3, which is known as “Certain Fuel Mixtures and the Alternative Fuel Credit,” is applied to some types of fuel claims under IRC Sections 6426 and 6427. These claims include biodiesel mixtures, renewable diesel mixtures, agri-biodiesel, SAF mixtures, and alternative fuels and mixtures. The eligibility of Schedule 3 claims varies based on the nature of the fuel claim and time of fuel activity.


Is Form 8849 Schedule 3 Still Available?

Yes, Form 8849 Schedule 3 is still available, but under particular circumstances.

The IRS has not made Form 8849 Schedule 3 unavailable yet. Nonetheless, some Section 6427 fuel payments became ineligible if the sale, use, or removal occurred after December 31, 2024.

This means:
1)Schedule 3 may still be relied upon for the filing of eligible claims concerning fuel activities that took place up until December 31, 2024.

2)Schedule 3 may not be relied upon for filing new claims for those expired fuel payments made after 2024.
3)The filing date alone does not determine eligibility. The important factor is when the qualifying fuel sale, use, or removal occurred.


What Does the IRS Mention About Schedule 3 in the "What's New" Section?

The IRS Form 8849 instructions explain that certain Section 6427 payments expired after 2024.

The IRS specifically states:

The section 6427 payments for mixtures of biodiesel, renewable diesel, agri-biodiesel (as allowed under section 6426(c)(5)), sustainable aviation fuels, and alternative fuels and mixtures expired for sales, uses, or removals occurring after 2024. 

Do not file Schedule 3 (Form 8849) for any claims related to these payments after 2024.

Understanding the Applicable Dates

Fuel Activity Date 

Schedule 3 Availability 

Applicable Form/Revision 

Sales, uses, or removals occurring on or before December 31, 2024 

Schedule 3 may be used if the claim meets IRS eligibility requirements 

Form 8849 (August 2014 revision) and Schedule 3 (Form 8849), January 2023 

Sales, uses, or removals occurring after December 31, 2024 

Schedule 3 cannot be used for these expired Section 6427 payments 

Do not file Schedule 3 for these claims 


Can I Claim Any Other Fuel Mixtures Through Schedule 3 After 2024?
No. Form 8849 Schedule 3 is specifically designed for the fuel-related claims identified by the IRS under the applicable Section 6426 and Section 6427 provisions.

The fuel categories covered under these provisions include:
1)Biodiesel mixtures
Mixtures of biodiesel and diesel fuel that qualify under IRS requirements.
2)Renewable diesel mixtures
Qualifying renewable diesel blended with diesel fuel.
3)Agri-biodiesel mixtures
Agri-biodiesel claims allowed under Section 6426(c)(5).
4)Sustainable aviation fuel (SAF) mixtures
Qualifying sustainable aviation fuel mixtures.
5)Alternative fuels and alternative fuel mixtures
Fuel types and mixtures that qualify under the alternative fuel credit provisions.

The IRS January 2023 revision of Schedule 3 was specifically used to report allowable claims for these fuel-related payments.

As Schedule 3 only deals with these particular claims for fuel mixtures and alternative fuels, there is no category of unconnected fuel mixture claims which can be claimed via Schedule 3 post-2024.

For fuel activity occurring after December 31, 2024, these expired Section 6427 payments cannot be claimed using Form 8849 Schedule 3. 

Visit the official IRS page stating about the Section 6427 fuel mixtures.


When Is Form 8849 Schedule 3 Due?

The filing deadline for Schedule 3 depends on the quarter in which the qualifying fuel activity occurred. Generally, the claim must be filed by the last day of the first calendar quarter following the earliest quarter included in the claim.
Example:

Fuel Activity Period 

Schedule 3 Filing Deadline 

January – March 2024 (Q1) 

June 30, 2024 

April – June 2024 (Q2) 

September 30, 2024 

July – September 2024 (Q3) 

December 31, 2024 

October – December 2024 (Q4) 

March 31, 2025 

The filing deadline is based on the claim period, while eligibility is based on whether the fuel activity occurred before or after the IRS expiration date.


Which Schedule 3 Claims Can Still Be Filed Now?

The important distinction is: The activity date determines whether Schedule 3 is allowed. The filing date determines whether the claim is timely.

Based on the IRS expiration rules:

Scenario 

Schedule 3 Eligibility 

Can It Be Filed Now? 

Fuel mixture activity during Q1 2024 

Eligible before expiration 

Only if it meets the applicable filing deadline requirements 

Fuel mixture activity during Q2 2024 

Eligible before expiration 

Only if it meets the applicable filing deadline requirements 

Fuel mixture activity during Q3 2024 

Eligible before expiration 

Only if it meets the applicable filing deadline requirements 

Fuel mixture activity during Q4 2024 

Eligible before expiration 

Yes, because the normal deadline extends into 2025 (March 31, 2025) 

Fuel mixture activity after December 31, 2024 

Not eligible 

No


Therefore, the primary example where a Schedule 3 claim naturally extends into 2025 is:

Q4 2024 Fuel Activity

  • Qualifying activity occurred: October 1, 2024 – December 31, 2024

  • The activity occurred before the Section 6427 expiration date.

  • The Schedule 3 deadline is March 31, 2025.

  • The claim must use the applicable pre-expiration Schedule 3 revision referenced by the IRS.


Is Schedule 3 Completely Removed From Form 8849?

No. Schedule 3 has not been completely removed from Form 8849. For eligible fuel-related claims involving removals, sales, or uses occurring before January 1, 2025, taxpayers may file using the August 2014 revision of Form 8849 with the 2023 version of Schedule 3. The latest version of Schedule 3 should not be used for these prior-period claims.

For removals, sales, or uses occurring after December 31, 2024, Schedule 3 cannot be used for expired Section 6427 fuel payment claims. 

Other Form 8849 schedules continue to be available for other eligible excise tax refund claims.
