IFTA Filing Deadlines
Know when your IFTA returns are due to avoid penalties and maintain compliance with all jurisdictions.
Quarterly Filing Schedule
IFTA returns are filed quarterly with your base jurisdiction. Each quarter has a specific filing deadline that falls approximately one month after the quarter ends.
| Quarter | Period | Due Date |
|---|---|---|
| Q1 (Jan-Mar) | January 1 - March 31 | April 30 |
| Q2 (Apr-Jun) | April 1 - June 30 | July 31 |
| Q3 (Jul-Sep) | July 1 - September 30 | October 31 |
| Q4 (Oct-Dec) | October 1 - December 31 | January 31 |
Important Notes
If the deadline falls on a weekend or holiday, the due date is typically extended to the next business day. However, it's best to file early to avoid any issues.
What Happens If You Miss a Deadline?
Missing an IFTA filing deadline can result in:
1.
Late filing penalties: Most jurisdictions charge $50 or more for late returns
2.
Interest charges: Interest accrues on any unpaid tax liability from the due date
3.
License suspension: Continued non-compliance can result in IFTA license revocation
Filing Even With No Activity
You must file an IFTA return every quarter, even if you had no qualified vehicle activity during that period. Simply file a "zero return" indicating no miles traveled and no fuel purchased.
Failure to file a zero return can still result in penalties and may affect your IFTA license standing.
