How to read it
The standard IFTA due date is the last day of the month following the end of the quarter: April 30, July 31, October 31 and January 31. The table adds the weekday for each date and the next business day when the date lands on a Saturday or Sunday. It does not account for holidays or for any extension a jurisdiction announces.
Dates are standard calendar rules calculated when the site is built. Always confirm the deadline and any penalty with your base jurisdiction; we do not state penalty amounts because they vary.
Questions
What happens when the due date falls on a weekend?
The usual rule is that the deadline moves to the next business day. Holidays can move it further, so confirm with your base jurisdiction.

Q1 (January to March) is due April 30, Q2 (April to June) July 31, Q3 (July to September) October 31, and Q4 (October to December) January 31 of the next year.
Where do I file?
With your IFTA base jurisdiction (the state or province where your IFTA license was issued), not with each state you drove in.
