How to File
The International Fuel Tax Agreement Reporting Forms (DR 0122) are available on our IFTA Forms Web page. There are fill-in versions that calculate the tax for each quarter. These forms are then printed and mailed to the department.
These are filed quarterly and are due at the end of the month following the end of the quarter (for example, January - March return is due April 30). If the end of the month falls on a holiday or weekend, the report is due on the next business day. A tax return is required even if a truck is not operated during a quarter.
Penalty and interest will be due if the tax return or payment is not postmarked by the due date. The late penalty is $50 or 10% of the tax due, whichever is greater. Interest is calculated only on a jurisdiction where tax is due.
