RMFT-5-X, Amended Return/Claim for Credit Motor Fuel Tax for Distributor Instructions
General Information
Who must file this return?
You must file Form RMFT-5-X to correct your original return, to correct your previously filed amended return, or to claim credit for overpayment of Illinois Motor Fuel Tax.
You must file a separate amended return with supporting schedules and documentation for each reporting period affected by a correction or credit.
What penalties may I owe?
You owe a late-filing penalty if you do not file a processable return by the due date, a late-payment penalty if you do not pay the tax you owe by the date the tax is due, and a bad check penalty if your remittance is not honored by your financial institution. Interest is calculated on tax from the day after the original due date of your return through the date you pay the tax.
We will bill you for penalties and interest. For more information about penalties and interest, see Publication 103, Penalties and Interest for Illinois Taxes, available on our website at tax.illinois.gov.
