IFTA Quarterly Filing Guide for Owner-Operators (Step-by-Step)
The Short Answer
IFTA is filed quarterly (April 30, July 31, Oct 31, Jan 31). Report every mile driven per state and every gallon of fuel bought per state. Modern ELDs + trucking accounting software make it a 20-minute quarterly task if you keep receipts current.
IFTA is a filing everyone hates and everyone eventually files late. Here is the process that makes it a 20-minute quarterly task.
IFTA (International Fuel Tax Agreement) is the mechanism that redistributes fuel tax between states based on where you drove and where you fueled. Any CDL truck operating in 2+ IFTA jurisdictions must file quarterly.
IFTA Quarterly Deadlines
| Quarter | Period | Due |
|---|---|---|
| Q1 | Jan–Mar | April 30 |
| Q2 | Apr–Jun | July 31 |
| Q3 | Jul–Sep | October 31 |
| Q4 | Oct–Dec | January 31 |
What You Report
- Total miles driven per state (loaded + empty)
- Total gallons of fuel purchased per state
- Vehicle info (VIN, plate, IFTA account)
The Modern IFTA Workflow
- ELD auto-tracks miles per state (Motive, Samsara, KeepTruckin)
- Fuel card auto-tracks state fuel purchases (EFS, RTS, Comdata)
- Trucking software (Rigbooks, TruckingOffice) merges both into a report
- File on your base state's IFTA portal — takes 15–20 min if data is clean
- Pay any tax owed by the deadline
The 'lost receipt' trap
IFTA audits check receipts, not just card records. Even with a fuel card, keep every physical receipt for 4 years. Photograph them and store in cloud folders by quarter.
Common IFTA Mistakes
- Only counting loaded miles (report ALL miles including empty)
- Forgetting personal-use miles (deduct those separately)
- Missing state fuel taxes bought outside your fuel card network
- Filing late — penalty is $50 minimum + interest
- Not filing a 'zero' return in quarters you didn't run
When You Get Money Back
If you drove more miles in a low-tax state than you fueled there (or fueled more in a high-tax state than you drove), IFTA can refund you. On average, IFTA nets to near-zero for a solo operator. The point is compliance, not profit.
Frequently Asked Questions
Do owner-operators have to file IFTA?+
Yes if you operate a CDL truck in 2+ IFTA jurisdictions. Non-CDL box trucks under 26,000 lbs are usually exempt but check your base state.
What's the penalty for filing IFTA late?+
$50 minimum plus 1% interest per month on any tax owed. Chronic late filing can trigger IFTA license suspension.
Can I do IFTA myself?+
Yes — most owner-operators self-file with the help of ELD data and trucking software. It's a 20-minute quarterly task once systems are set up.
