IFTA due dates for 2027
IFTA returns are due on the last day of the month after each quarter. In 2027, three of the four dates fall on a weekend and move to the next Monday. Here is every deadline, and what is due with it.
Quarterly deadlines
| Quarter | Period covered | Return and payment due |
|---|---|---|
| Q4 2026 | Oct 1 to Dec 31, 2026 | Monday, February 1, 2027 Jan 31 falls on a Sunday |
| Q1 2027 | Jan 1 to Mar 31, 2027 | Friday, April 30, 2027 |
| Q2 2027 | Apr 1 to Jun 30, 2027 | Monday, August 2, 2027 Jul 31 falls on a Saturday |
| Q3 2027 | Jul 1 to Sep 30, 2027 | Monday, November 1, 2027 Oct 31 falls on a Sunday |
| Q4 2027 | Oct 1 to Dec 31, 2027 | Monday, January 31, 2028 |
The return and the payment are due on the same day. A return counts as on time if it is filed online or postmarked by the due date.
The weekend and holiday rule
When the last day of the month is a Saturday, a Sunday or a legal holiday, the due date moves to the next business day. Some jurisdictions observe their own holidays, so confirm the date with your base jurisdiction if a deadline falls next to one.
You must file even with no miles
An IFTA license holder files a return every quarter. That includes a quarter with no operations and a quarter in which all miles were in your home state. A "zero" return filed late can still be charged the $50 late penalty.
License and decal renewal
IFTA licenses and decals are valid for one calendar year and expire on December 31. Renew with your base jurisdiction before the end of the year. Most jurisdictions let you display the previous year's decals through the end of February while the new ones arrive, as long as your renewal is in order.
How to never miss one
- Start collecting fuel and mileage files in the first week after the quarter ends, not in the last week before the deadline.
- Run your checks early. Missing miles and duplicate fuel take time to chase.
- File a few days ahead. State portals slow down on the last day.
IFTAflow keeps a deadline calendar for every carrier, sends data requests when the quarter ends and reminds you as the due date approaches.
Common questions
What happens if I file late?
The penalty is $50 or 10% of the net tax due, whichever is greater, plus interest. See our guide to the IFTA late filing penalty.
Is the due date the same in every state?
Yes. All IFTA jurisdictions use the same quarterly schedule. Only the handling of local holidays can differ.
Which rates do I use for each quarter?
Each quarter has its own rate matrix from IFTA, Inc. See the Q4 2026 IFTA tax rates.
