Reporting: Do I have to file the quarterly IFTA fuel tax returns?
Yes. If you are licensed for IFTA, a quarterly return must be filed even if you had no activity for the quarter.
In order to complete the IFTA return, you must maintain records of all fuel purchases and miles driven in each IFTA jurisdiction for the quarter. Failure to keep adequate records may result in disallowed credits and your fleet MPG may be set to 4.0 as permitted under the Motor Carrier Fuel Tax Act.
The quarterly returns are due on April 30, July 31, October 31 and January 31 of each year. If the due date falls on a weekend or holiday, the returns are due on the next business day. Failure to file the required quarterly return will result in the Department issuing computed assessments against your account. Availability to file your quarterly returns online in the IFTA IPC system begin the day following the end of a quarter (April 1, July 1, October 1 & January 1).
