Don't get caught off guard. A complete guide to 2025 IFTA filing deadlines, late penalties, and how to avoid jeopardy assessments.
Mark Your Calendars: 2025 IFTA Deadlines
Missing an IFTA deadline isn't just an annoyance—it's expensive. To keep your trucking business compliant and penalty-free, you need to know exactly when your quarterly returns are due.
Quarterly Filing Schedule
| Quarter | Reporting Period | Due Date |
|---|---|---|
| 1st Quarter | January - March | April 30, 2025 |
| 2nd Quarter | April - June | July 31, 2025 |
| 3rd Quarter | July - September | October 31, 2025 |
| 4th Quarter | October - December | January 31, 2026 |
The "Weekend Rule"
If a due date falls on a Saturday, Sunday, or legal holiday, the deadline is automatically extended to the next business day. However, relying on this grace period is risky. We always recommend filing at least a few days early.
The Cost of Failure: Penalties & Interest
Filing late triggers an immediate financial hit. The standard IFTA penalty is:
- $50.00 or 10% of the net tax liability, whichever is greater.
- Plus, interest accrues monthly (usually around 0.4167% per month) on all taxes owed.
Jeopardy Assessments
If you fail to file entirely, your base jurisdiction may issue a "jeopardy assessment." This means they will estimate your liability based on your past history or industry averages—and these estimates are almost always higher than what you actually owe. It's their way of forcing you to file.
FastIFTA Solution: Never miss a deadline again. FastIFTA sends automated push notifications and email reminders as the quarter closes, giving you plenty of time to snap your receipts and generate your report.
