IFTA Quarterly Filing Checklist

Q1 (Jan-Mar): due April 30. Q2 (Apr-Jun): due July 31. Q3 (Jul-Sep): due October 31. Q4 (Oct-Dec): due January 31. Late filings incur a $50 penalty or 10% of tax due (whichever is greater) plus interest. File on time even if you owe nothing.

First, check your fleet card or credit card statements — they usually contain enough detail to reconstruct records. Truck stop loyalty program accounts (Love's, Pilot) often store purchase history online. If records are truly lost, you may be assessed tax on miles driven without purchase credit, resulting in higher tax owed.

Yes. You must file a return every quarter, even if all miles were driven in your base state and no tax is owed. Filing a zero-return keeps your license active. Failure to file for two consecutive quarters can result in license revocation.
