Tool Notes
- The standard IFTA due date is the last day of the month following the quarter end: Q1 returns by April 30, Q2 by July 31, Q3 by October 31, Q4 by January 31 of the following year.
- When a due date falls on a weekend or public holiday, some base jurisdictions accept the next business day — but not all. The tool flags this caveat; the base jurisdiction controls what date is actually accepted.
- Q4 returns are due in January of the following year. If you select Q4 2026, the tool shows a January 2027 planning date — that is correct.
- This tool does not calculate any tax owed, does not communicate with IFTA systems, and does not submit a return. It only shows the calendar date to use as a planning reference.
- New authorities filing their first partial quarter should confirm with the base jurisdiction whether a return is required and what due date applies — the standard quarterly cycle may not apply to a mid-quarter start.
- IFTA Canada member jurisdictions follow the same quarterly schedule, but Canadian provincial rules and fuel tax rates are separate. Verify with the base jurisdiction if operating in Canadian provinces.
- The most common misuse of this tool is treating the planning date as the confirmed filing deadline without checking the base jurisdiction. Some base jurisdictions post their own notices when a standard due date shifts for a holiday — the tool's output is a starting point, not a substitute for that notice.
- New entrants who start operations mid-quarter often ask whether a partial-quarter return is required. Most base jurisdictions require a return for any quarter in which the fleet operated, even if only for part of the quarter. Confirm the first-return obligation with the base jurisdiction when setting up the IFTA account.
- Carriers who miss the deadline and owe a penalty should contact the base jurisdiction directly to understand the current penalty calculation, whether a first-time waiver is available, and what interest rate applies to the unpaid balance. The tool does not calculate penalties or interest.

FAQ
Does this tool file an IFTA return?
No. It shows a planning date only. Quarterly IFTA returns are filed through the base jurisdiction's own filing system — online portal, paper form, or third-party software accepted by that jurisdiction.
Can a due date shift for weekends or holidays?
Yes, and the shift depends on what the base jurisdiction accepts. Some extend the deadline to the next business day; others do not. Confirm the accepted due date with the base jurisdiction before assuming any extension applies.
What is the due date for Q4 returns?
Q4 returns cover October through December. The standard planning date is January 31 of the following year. When Q4 2026 is selected, the tool shows a January 2027 date — that is the correct quarter.
Is there an extension process if I can't file on time?
Some base jurisdictions grant filing extensions on request. Extensions for payment are less common — interest typically accrues from the original due date even if a filing extension is granted. Contact the base jurisdiction for current extension procedures.
Does the tool use external APIs or save input?
No. The calculation runs entirely in the browser. No data is transmitted to any server and no input is retained after the page closes.
