IFTA Reporting Guide: How ELDs Automate Fuel Tax
Rules, prices and device details on this page were checked October 2026 against the official sources listed at the bottom. Where a provider doesn't publish a number, we say so instead of guessing.
Ask any small carrier which paperwork they hate most, and IFTA comes up fast. Every quarter you have to add up the miles you drove in every state and province, match them against every gallon you bought, and file a return. Miss a deadline and there's a penalty. Get audited without records and it's worse. The good news is that the data your ELD or telematics system already collects can do most of the heavy lifting. Here's how IFTA works and how to make it easier. Facts checked October 2026 with IFTA, Inc. and state IFTA pages.
What IFTA Is
The International Fuel Tax Agreement is a deal between the lower 48 US states and the Canadian provinces that simplifies fuel tax for trucks that cross borders. Instead of filing a fuel tax return in every state you drive through, you get one IFTA license from your home (base) jurisdiction and file one quarterly return there. Your base state then splits the money among the other jurisdictions.
Who needs an IFTA license
You need IFTA if you operate a qualified motor vehicle across state or provincial lines. Per Virginia DMV's IFTA guidance, a qualified motor vehicle is one used for transporting people or property that:
- Has two axles and a gross vehicle weight or registered gross weight over 26,000 pounds, or
- Has three or more axles regardless of weight, or
- Is used in combination, when the combined weight exceeds 26,000 pounds.
Recreational vehicles are generally excluded. If you only run in your home state, you don't need IFTA, though your state may have its own fuel tax rules.
How the tax works
The idea is simple: you pay fuel tax to each jurisdiction based on the miles you drove there, not where you bought the fuel. You figure your fleet's average miles per gallon, work out how many gallons you "used" in each jurisdiction, and compare that to the tax you already paid at the pump there. If you bought more fuel in a state than you used there, you get a credit. If you used more than you bought, you owe. Our IFTA calculator walks through the math.
Quarterly Deadlines
IFTA returns are due the last day of the month after each quarter ends:
| Quarter | Months | Return due |
|---|---|---|
| Q1 | January to March | April 30 |
| Q2 | April to June | July 31 |
| Q3 | July to September | October 31 |
| Q4 | October to December | January 31 |
If a due date falls on a weekend or holiday, it moves to the next business day. A few things catch people out:
- You must file even if you didn't drive. A zero return is still required for every quarter you hold a license.
- Late penalties add up. Virginia DMV, applying the IFTA rules, lists the late penalty as $50 or 10% of the net tax due, whichever is greater, plus interest on unpaid tax.
- Some states allow annual filing in special cases. Virginia, for example, allows it for carriers that drive fewer than 5,000 miles a year outside the state. Check with your base state.
Mark the four dates in your calendar now. It's the easiest money you'll ever save.
A good habit is to close out each quarter in the first week of the next month. That leaves time to chase missing receipts and fix GPS gaps before the deadline sneaks up.
Required Records
IFTA requires you to keep records to back up every return, and you have to keep them for 4 years from the return's due date or filing date, whichever is later. If you're audited, these records are what stand between you and an estimated assessment.
Jurisdiction miles
Your distance records need to show the miles driven in each jurisdiction. Virginia DMV lists what individual trip records should include, such as:
- Date of the trip (start and end)
- Trip origin and destination
- Routes of travel
- Beginning and ending odometer or hubometer readings
- Total trip miles and miles by jurisdiction
- Unit number or vehicle ID
- Your name as the licensee
GPS or telematics data can serve as your distance records if the system captures the right detail. Ask your provider whether its IFTA reports meet your base state's requirements.
Fuel receipts
Every fuel purchase needs a receipt showing:
- Date of purchase
- Seller's name and address
- Number of gallons or liters
- Fuel type
- Price per gallon or total amount
- Unit number or vehicle ID
- Purchaser's name
A missing receipt means no tax paid credit for that fuel, so you'd pay the tax twice. Fuel card data helps a lot here, since it captures most of these fields automatically.
Audits
Base jurisdictions audit IFTA licensees to check that returns match records. If your records are incomplete, auditors can estimate your tax, and the estimate rarely goes your way. The best audit defense is boring: complete trip records, a receipt for every gallon, and returns that tie back to both. Keep everything organized by quarter so you can hand it over without a scramble.
How ELDs Automate Mileage by State
This is where your ELD earns its keep. An ELD records the truck's location at duty status changes and at regular intervals while driving. Most providers go further, using full GPS tracking to calculate miles driven in each jurisdiction automatically.
What the software does
- Tracks state line crossings. GPS data shows exactly when the truck enters and leaves each jurisdiction.
- Totals miles by jurisdiction. The system adds up miles per state for every truck, every quarter.
- Imports fuel purchases. Many systems pull fuel card data or let drivers snap receipts in the app.
- Builds the report. You get a summary of miles and gallons by jurisdiction, ready to enter into your state's IFTA return.
- Flags gaps. Good systems highlight missing data, such as a GPS outage or a truck with no fuel purchases.
What you still have to do
Software helps, but you're still responsible for the return. Review the report each quarter, fix gaps, make sure every receipt is matched, and file with your base state. Some providers and third party services will file for you, but double check their numbers.
Tips for clean data
- Make sure every truck has a working ELD or GPS unit all quarter. Gaps mean manual work.
- Use fuel cards wherever you can, and keep paper receipts for any cash purchases.
- Check odometer readings against GPS miles once a quarter. Big differences need a look.
- Assign trucks to the right IFTA license if you run more than one company.
Common IFTA Mistakes
Most IFTA problems come from a handful of habits. Fix these and your returns, and any audit, get a lot easier.
- Filing late or skipping a zero quarter. Late returns cost at least $50 each under the IFTA penalty rules, even if you owe nothing.
- Losing receipts. No receipt, no credit. That fuel gets taxed twice.
- Using estimated miles. Rounded or guessed mileage won't hold up in an audit. Use trip records or GPS data.
- Mixing fuel types. Report diesel, gasoline and other fuels separately, as your return requires.
- Forgetting a jurisdiction. Even a few miles through a state belong on the return.
- Using old rates. Rates change, sometimes every quarter. Use the current IFTA rate matrix or your state's software.
Best ELDs for IFTA
Most full featured ELD platforms include IFTA reporting, though sometimes only on higher tiers. A few we've reviewed:
- Motive: automated IFTA mileage and fuel card integration. See our Motive review.
- Samsara: IFTA reports built from GPS data. See our Samsara review.
- HOS247: IFTA state mileage reports on its higher plans, with published pricing. See our HOS247 review.
- LytxOne: IFTA in the same platform as video safety. See our Lytx review.
- Omnitracs: offers Omnitracs Tax Manager for fuel tax. See our Omnitracs review.
When comparing, ask whether IFTA is included or costs extra, whether it imports fuel card data, and whether you can export the report in a format your state accepts. Our list of the best ELD devices notes which picks include IFTA.

Frequently Asked Questions
When are IFTA returns due?
IFTA returns are due April 30, July 31, October 31 and January 31, covering the quarter just ended. If the date falls on a weekend or holiday, it moves to the next business day.
Do I have to file IFTA if I did not drive?
Yes. You must file a return every quarter you hold an IFTA license, even if you had no miles or fuel purchases.
How long do I keep IFTA records?
Keep IFTA records for 4 years from the return due date or filing date, whichever is later.
Can my ELD do my IFTA report?
Many ELD and telematics systems calculate miles by jurisdiction from GPS data and import fuel purchases to build the report. You still need to review it and file it with your base jurisdiction.
