Publication 378
Fuel Tax Credits and Refunds
(Revised: 12/2002)


3. Filing Claims

This chapter tells you how and when to make a claim for a credit or refund of excise taxes on fuels. This chapter also covers recordkeeping requirements, interest and penalty provisions, and when to include the credit or refund in your income.

General Information

Generally, you will provide all the information needed to claim a credit or refund when you properly complete the claim form. In some cases, you will have to attach additional information. You need to keep records that support your claim for a credit or refund.

FILES: Keep at your principal place of business all records needed to enable the IRS to verify that you are the person entitled to claim a credit or refund and the amount you claimed. No special form is required, but the records should establish all the following information.

Ultimate purchaser.   If you are an ultimate purchaser, you must keep the following records.

  • The number of gallons purchased and used during the period covered by your claim.
  • The dates of the purchases.
  • The names and addresses of suppliers and amounts purchased from each in the period covered by your claim.
  • The nontaxable use for which you used the fuel.
  • The number of gallons used for each nontaxable use.

It is important that your records show separately the number of gallons used for each nontaxable use that qualifies as a claim. If the fuel is exported, you must have proof of exportation.

For more information about keeping records, see Publication 583, Starting a Business and Keeping Records, or Publication 552, Recordkeeping for Individuals.

Gasohol blending.   If you are a gasohol blender, you must keep the following information for each batch of gasohol.

  • The name and address of the person that sold you the gasoline.
  • The date and location of the purchase of the gasoline.
  • The number of gallons of gasoline.
  • The name and address of the person that sold you the alcohol.
  • The date and location of the purchase of the alcohol.
  • The number of gallons and type of alcohol.

Registered ultimate vendor.   If you are a registered ultimate vendor (as discussed in chapter 1 under Undyed Diesel Fuel and Undyed Kerosene), you must keep certain information pertaining to the sale of the fuel.

To make a claim, you must have sold the diesel fuel or kerosene at a tax-excluded price, repaid the tax to the buyer, or obtained the buyer's written consent to the allowance of the claim.

To make a claim, you must have a registration number that has not been revoked or suspended. If you are an ultimate vendor (farming and state use), you must have a UV registration number. If you are an ultimate vendor (blocked pump), you must have a UP registration number. You can get either registration number from the IRS by completing Form 637, Application for Registration (For Certain Excise Tax Activities), and providing the information requested in its instructions.

Farming and state use.   If you sell undyed diesel fuel or undyed kerosene for use on a farm for farming purposes or for use by a state or local government, you must keep the following information.

  • The name and taxpayer identification number of each person (farmer, custom harvester, or government unit) that bought the fuel.
  • The number of gallons sold to each person.
  • An unexpired certificate from the buyer. See Table 3-1.

Blocked pump.   If you sell undyed kerosene from a pump that qualifies as a blocked pump because it is locked by you after each sale and is unlocked by you at the request of the buyer, you must keep the following information for each sale of more than 5 gallons.

  • The date of each sale.
  • The name and address of the buyer.
  • The number of gallons sold to that buyer.

Blending.   If you sell undyed kerosene for blending with diesel fuel in an area under a declaration of extreme cold and the blend will be sold for use or used for heating purposes, you must keep the following information.

  • The number of gallons sold to each person.
  • An unexpired certificate from the buyer for each purchase of kerosene. See Table 3-2.

Taxpayer identification number.   To file a claim, you must have a taxpayer identification number. Your taxpayer identification number can be any of the following.

  • Employer identification number (EIN).
  • Social security number (SSN).
  • Individual taxpayer identification number (ITIN), if you are an alien individual and do not have and are not eligible to get an SSN.

If you normally file only a U.S. individual income tax return (such as Form 1040 or 1040NR), use your SSN or ITIN. You get an SSN by filing Form SS-5, Application for a Social Security Card, with the Social Security Administration. To get an ITIN, file Form W-7, Application for IRS Individual Taxpayer Identification Number, with the IRS.

If you operate a business, use your EIN. You get an EIN by filing Form SS-4, Application for Employer Identification Number, with the IRS.

Filing date on holiday or weekend.   If the last day for filing your claim falls on a Saturday, Sunday, or legal holiday, the due date is delayed until the next business day.

Credit or refund.   A credit is an amount you claim on your income tax return when you file it at the end of the year. If you meet certain requirements (discussed later), you can claim a refund during the year.

Credit only.   You can claim the following taxes only as a credit.

  • Tax on gasoline, gasohol, or aviation gasoline used on a farm for farming purposes.
  • Tax on fuels used for nontaxable uses if the total for the tax year is less than $750.
  • Tax on fuel you did not include in any claim for refund previously filed for any quarter of the tax year.

Claiming a Credit

You make a claim for credit on Form 4136 and attach it to your income tax return. Do not claim a credit for any amount for which you have filed a refund claim.

When to file.   You can claim a fuel tax credit on your income tax return for the year you used the fuel (or sold the fuel in the case of gasohol blender or registered ultimate vendor claims).

CAUTION: Once you have filed a Form 4136, you cannot file an amended return to show an increase in the number of gallons reported on a line of that form. See the following discussion for when you can file a claim on an amended return.

Fuel tax claim on amended return.   You may be able to make a fuel tax claim on an amended return for the year you used or sold the fuels. Generally, you must file an amended return by the later of 3 years from the date you filed your original income tax return or within 2 years from the time you paid the income tax. A return filed early is considered to have been filed on the due date.

You can file an amended return to claim a fuel tax credit if any of the following apply.

  • You did not claim any credit for fuel taxes on Form 4136 for the tax year.
  • Your credit is for gasohol blending, discussed in chapter 1.
  • Your credit is for a claim group, explained next, for which you did not previously file a claim on Form 4136 for the tax year.

Claims on Form 4136 (other than for gasohol blending) are separated into seven claim groups. Once you file Form 4136 with a claim for a group, you cannot file an amended return with another claim for that group. However, you can file an amended return with a claim for another group.

For each tax year, you can make only one claim for each group.

Example.   You file your 2002 income tax return and claim a fuel tax credit. Your Form 4136 shows an amount on line 1b for use of gasoline on a farm for farming purposes. This is a Group I claim. You cannot amend your return to claim a credit for an amount on line 2b for use of aviation gasoline on a farm for farming purposes (Type of Use 1) since that is also a Group I claim. However, if you used aviation fuel on a farm for farming purposes, you can amend your return to claim the credit for that fuel tax because that would be a Group VI claim reported on line 5b (Type of Use 1).

How to claim a credit.   How you claim a credit depends on whether you are an individual, partnership, corporation, S corporation, or farmers' cooperative.

Individuals.   You claim the credit on line 68 of Form 1040. Check box b on line 68. If you would not otherwise have to file an income tax return, you must do so to get a fuel tax credit.

Partnerships.   A partnership cannot claim the credit on Form 1065, U.S. Return of Partnership Income. The partnership must include on line 25 of Schedule K-1 (Form 1065), Partner's Share of Income, Credits, Deductions, etc., each partner's share of the number of gallons of each fuel sold or used for a nontaxable use, the type of use, and the applicable credit per gallon. Each partner claims the credit on his or her income tax return for his or her share of the fuel used by the partnership.

An electing large partnership can claim the credit on line 27 of Form 1065-B, U.S. Return of Income for Electing Large Partnerships.

Corporations.   To claim the credit, corporations use either line 32g of Form 1120, U.S. Corporation Income Tax Return, or line 28g of Form 1120-A, U.S. Corporation Short-Form Income Tax Return.

S corporations.   To claim the credit, S corporations use line 23c of Form 1120S, U.S. Income Tax Return for an S Corporation.

Farmers' cooperative associations.   If the cooperative must file Form 990-C, Farmers' Cooperative Association Income Tax Return, it uses line 32g to claim the credit.

Trusts.   Trusts required to file Form 1041, U.S. Income Tax Return for Estates and Trusts, use line 24g to claim the credit.
