RMFT-11-A, Illinois Motor Fuel Tax Refund Claim Instructions

General Information

Who must file Form RMFT-11-A?

Form RMFT-11-A, Illinois Motor Fuel Tax Refund Claim, can be filed by anyone who has purchased motor fuel, paid the Illinois Motor Fuel Tax due on that purchase, and used the fuel for off-highway or nontaxable purposes.

Is there a deadline for filing a refund claim?

If you are not a licensed distributor, you may file a claim for gallons on which the tax was paid two years ago or less. Licensed distributors may only file a claim for gallons on which the tax was paid one year ago or less.

Can I file this form electronically?

Yes, you can use MyTax Illinois at mytax.illinois.gov to file your Form RMFT-11-A.

Note: We use filed claims to establish Motor Fuel Tax refund accounts for taxpayers, so you must have previously filed a refund claim using a paper Form RMFT-11-A in order to use MyTax Illinois to file subsequent claims.

What records do I need to provide in order to qualify for a refund?

We will not approve a claim unless it can be directly supported by invoices, sales slips, statements of account, or monthly statements. You may submit reproductions in lieu of originals, provided they are legible. However, we may require original documentation to verify a purchase.

All purchase documentation must contain the following:

  • the date of delivery;
  • the name and address of the purchaser (which must be the name of the claimant);
  • the name and address of the seller;
  • the number of gallons purchased and the price per gallon;
  • the Illinois Motor Fuel Tax as a separate item if the purchase was from other than a retail outlet; and
  • the receipt showing payment.

What qualifies as proof of payment?

Acceptable forms of proof of payment include bank statements, cancelled checks, and statements of account.

How long do refund claims take to process, and how will the refund be paid?

Claims for refund of the motor fuel tax must be paid within 90 days of the receipt of a processable return, at which time the refund will start accruing interest. The refund will be issued as a paper check unless an electronic payment method is arranged through the Office of the Illinois Comptroller.

What if I need help?

If you need help, email us at REV.MF@illinois.gov or call us weekdays between 8:00 a.m. and 4:00 p.m. at 217 782-2291.
