IFTA quarterly deadlines and the records you need to keep
2026-11-10 · Mile-Tax team
If you run a qualified motor vehicle across state or provincial lines, you normally file an IFTA return every quarter. Always confirm details with your base jurisdiction, as rules and forms differ.
Usual due dates
- Q1 (January to March): April 30
- Q2 (April to June): July 31
- Q3 (July to September): October 31
- Q4 (October to December): January 31
If the date falls on a weekend or holiday it moves to the next business day.
What to keep
- Miles driven in each jurisdiction, per vehicle.
- Fuel purchase receipts: date, seller, gallons, price, vehicle.
- Trip records or the log your tracking app produced.
Most jurisdictions require records to be kept for four years. The tedious part is the miles per state. Mile-Tax records your route by GPS and splits miles by state, so the quarterly numbers are ready. We do not file for you: the app prepares figures, you file on your base state portal.
