IRS issues guidance for claiming 2018 and 2019 fuel tax credits

IRS provides window of Feb. 14 - Aug. 11 for filing Forms 8849

TAX ALERT  | 

The IRS recently released Notice 2020-8, providing the procedures for taxpayers to claim the fuel tax credits retroactively reinstated by the Taxpayer Certainty and Disaster Relief Act of 2019 (the Act) on Dec. 20, 2019. (See our prior alert on the passing of the act.) The notice provides the required procedures for claiming credits and/or payments allowed under section 6426(c) relating to biodiesel (including renewable diesel) mixtures, section 6426(d) relating to alternative fuels and section 6426(e) relating to alternative fuel mixtures. The notice also provides instructions for certain income tax credit claims for biodiesel, second generation biofuel, biodiesel mixtures and alternative fuel. 

Fuel taxes and fuel tax credits

The federal government imposes excise taxes on various types and uses of fuel. Fuel may be taxable when it is removed from a refinery or terminal under section 4081 or when it is sold or used in the operation of a motor vehicle, train, boat or aircraft under section 4041. However, there are several exemptions from these fuel taxes depending upon what the fuel is ultimately used for. Further, a taxpayer may be eligible for credits and payments that are available on the sale or use of certain fuels.

Excise tax credits

Section 6426 provides a credit against the excise taxes imposed by sections 4041 and 4081 for biodiesel mixtures, alternative fuels and alternative fuel mixtures.

Biodiesel mixture credit:  Under section 6426(c), a taxpayer that produces a biodiesel mixture for sale or for use in its trade or business may claim a credit against its section 4081 excise tax liability. The biodiesel mixture credit is $1.00 per gallon of biodiesel used in producing the biodiesel mixture. Section 6426(c)(3) defines ‘biodiesel mixture’ as a mixture of biodiesel and diesel fuel which is either sold or used by the taxpayer producing the mixture. In order to be eligible for the credit, the taxpayer must obtain a certificate from the biodiesel producer that identifies the biodiesel as such and provides the percentage of biodiesel in the product. The biodiesel mixture credit is available for fuel sold, used,or removed before Jan. 1, 2023.

Alternative fuel credit:  Under section 6426(d), a taxpayer that sells or uses an alternative fuel in its trade or business for use in motor vehicles, motorboats or aviation can claim a credit against its section 4041 excise tax liability. The alternative fuel credit is $0.50 per gallon or gallon equivalent, of alternative fuel. Alternative fuels include the following:

  • Liquefied petroleum gas (propane, butane, etc.)
  • P Series fuels (renewable non-petroleum-based fuels)
  • Compressed or liquefied natural gas
  • Liquefied hydrogen
  • Any liquid fuel that meets the carbon capture requirements of section 6426(d)(4) and that is derived from coal through the Fischer-Tropsch process (which converts a mixture of hydrogen and carbon monoxide into liquid fuel)
  • Compressed or liquefied gas derived from biomass 
  • Liquefied fuel derived from biomass.

Alternative fuels do not include ethanol, methanol, biodiesel or any fuel derived from the production of paper or pulp. In order to claim the credit, the taxpayer must be registered under section 4101 by filing Form 637, Application for Registration (for Certain Excise Tax Activities). The alternative fuel credit is available for fuel sold or used before Jan. 1, 2021.

Alternative fuel mixture credit:  Under section 6426(e), a taxpayer that produces an alternative fuel mixture can claim a credit against its section 4081 excise tax liability. The alternative fuel mixture credit is $0.50 per gallon of alternative fuel used to produce the mixture. An alternative fuel mixture is a mixture of an alternative fuel and gasoline, diesel or kerosene that the taxpayer uses or sells as a fuel. The alternative fuel mixture credit can be claimed only to the extent of the taxpayer’s excise tax liability, and taxpayers are not allowed to claim any excess credits as payments (as discussed in the next section). The alternative fuel mixture credit is available for fuel sold or used before Jan. 1, 2021.

Excess credits

After a taxpayer applies the fuel tax credits against its excise tax liability, as described above, an excess credit may occur due to the credit rate exceeding the tax rate. Section 6427(e) provides for a payment in the amount of the excess fuel tax credit for biodiesel mixtures or alternative fuels sold or used in the taxpayer’s trade or business.

A taxpayer may claim the excess excise tax credits allowed under section 6427(e) for any period that is not less than one week and that is for $200 or more. These claims must be filed on a Form 8849, Claim for Refund of Excise Taxes, on or before the last day of the first quarter following the claim period.

Taxpayers that are not eligible or do not timely file the Form 8849, for payment under section 6427(e), but otherwise qualify for fuel tax incentives under section 6426 can file a claim for a refundable income tax credit under section 34 pursuant to section 6427(k). To claim a refundable income tax credit under section 34, a taxpayer must file Form 4136, Credit for Federal Tax Paid on Fuels, with the taxpayer’s income tax return. Furthermore, a blender of biodiesel may elect out of the credits and payments under section 6426 and claim a nonrefundable income tax credit under section 40A (biodiesel and renewable diesel used as fuel) as an alternative to payments and credits allowed under sections 6426, 6427 and 34.

Notice 2020-8 procedures

When the Act was signed into law, it retroactively extended the fuel credits for fuel sold or used in 2018 and 2019. However, because the Forms 8849 are only considered timely if remitted within 30 days of the close of the quarter, most of the claim windows for the 2018 and 2019 credits had closed before the Act effectively reenacted them. To remedy this, Notice 2020-8 provides procedures taxpayers may follow to make a one-time claim for all the 2018 and 2019 credits and payments authorized by sections 6426(c), 6426(d) and 6427(e).

Procedures: Biodiesel mixture and alternative fuel credit

  • Submit claims for 2018 and 2019 biodiesel and alternative fuel incentives on Form 8849, Claim for Refund of Excise Taxes.
  • Include Form 8849, Schedule 3, Certain Fuel Mixtures and the Alternative Fuel Credit, with the submission and enter the amounts for the 2018 and 2019 biodiesel and alternative fuel incentives on Lines 2 and 3 of Schedule 3.

If the IRS does not pay the claims within 60 days of receipt of the claim, then the IRS will play the claim with interest as of the filing date and using the overpayment rate provided under section 6621.

Procedures: Alternative fuel mixture credit

In order to claim a credit for alternative fuel mixtures sold or used in 2018 and 2019 a taxpayer must comply with the following procedures:

  • For 2018 and 2019 all claims for the alternative fuel mixture credit under section 6426(e) must be made on Form 720X, Amended Quarterly Federal Excise Tax Return.
  • Taxpayers must file one Form 720X for 2018 claims and a separate Form 720X for 2019 claims.
  • Taxpayers must enter amounts for their 2018 and 2019 alternative mixture credit claims on Line 2 of Form 720X by quarter. Further, taxpayers must identify the type and amount of alternative fuel in the mixture for which they are claiming the alternative fuel mixture credit on Line 6 of Form 720X.
  • Taxpayers must follow the Form 720X instructions when preparing their submission to the extent the instructions do not conflict with the notice.

  • Taxpayers must be registered by the IRS via Form 637 to claim a credit for an alternative fuel or alternative fuel mixture.
  • Taxpayer claims for the alternative fuel mixture credit cannot exceed their section 4081 liability for the quarter in which the credit is being claimed. Further, the credit may not be applied against the tax for the Leaking Underground Storage Tank Trust Fund.
  • Taxpayers must maintain adequate records to substantiate eligibility for the 2018 and 2019 alternative fuel mixture credits.
  • Taxpayers that fail to file a Form 720, Quarterly Federal Excise Tax Return, and remit the section 4081 tax due for any quarter in 2018 or 2019 before submitting a claim allowed under section 6426(e) on Form 720X will experience a delay in the processing of the claim and related payment.

Generally, claims for the alternative fuel mixture credit must be made within three years from the time the return was filed or two years from the time the tax was paid, whichever is later.

Claims not affected by the notice

The notice does not affect the following claims for 2018 or 2019:

  • Nonrefundable income tax credits under section 40(b)(6) for second generation biofuel producers; taxpayers should continue to submit these claims for 2018 and 2019 on Form 6478, Biofuel Producer Credit.
  • Nonrefundable income tax credits under section 40A(b)(1) for biodiesel mixtures, section 40A(b)(2) for biodiesel (including renewable diesel), and section 40A(b)(4) for the small agri-biodiesel producer credit; taxpayers should continue to submit these claims for 2018 and 2019 on Form 8864, Biodiesel and Renewable Diesel Fuels Credit. Forms 8864 are included with a taxpayer’s income tax return in accordance with the instructions and the income tax return form. Taxpayers must reduce the credit claimed under this section if they already claimed a credit for the same fuel under sections 6426 and 6427.
  • Refundable income tax credits under section 34 for biodiesel mixtures or alternative fuels; taxpayers should continue to submit these claims for 2018 and 2019 on Form 4136, Credit for Federal Tax Paid on Fuels. Taxpayers must reduce the credit claimed under this section if they already claimed a credit for the same fuel under sections 6426 and 6427.

Conclusion

Notice 2020-8 provides the procedures taxpayers are required to use to make a one-time claim for the biodiesel and alternative fuel incentives for 2018 and 2019. Taxpayers that are required to be registered to claim a fuel tax credit should register with the IRS as soon as possible so that they have adequate time to receive their registration number from the IRS. Taxpayers who filed protective or anticipatory claims during 2018 and 2019 for payments and credits covered by this notice should refile their claims pursuant to the rules and procedures prescribed in the notice. The IRS will not treat as perfected any protective or anticipatory claims previously filed with the IRS that are not in accordance with the rules and procedures contained in the notice.

Taxpayers who think they might be eligible for biodiesel or alternative fuel tax incentives should contact their tax advisors to ensure that all rules and registration requirements are being complied with to obtain the credit.
