What's specific to New Jersey
New Jersey is a standard IFTA jurisdiction. Toll-heavy lanes mean carriers should reconcile actual miles vs. rate-con miles carefully.
How to file IFTA in New Jersey
- Compile your quarterly mileage by jurisdiction — including deadhead and detour miles. ELD reports (Samsara, KeepTruckin / Motive, Geotab) export this directly.
- Compile your fuel purchases by jurisdiction. Fleet-card CSVs from EFS, Comdata, WEX, or RTS produce this in one click; if you're paying by personal card, you'll be reconciling receipts manually.
- Calculate fleet MPG (total miles ÷ total gallons), then taxable gallons per state (state miles ÷ fleet MPG). Use the free IFTA calculator if you'd rather not do this by hand.
- Apply the current quarterly rate for New Jersey, then net it against fuel tax already paid at the pump in New Jersey.
- File through the New Jersey Motor Vehicle Commission IFTA portal by the quarterly deadline.
- Retain receipts, mileage records, and ELD reports for at least 4 years in case of audit.
Common New Jersey IFTA mistakes
Filing a zero return late
Even if you didn't run New Jersey this quarter — or didn't run at all — you're still required to file. A late zero return triggers the same $50 minimum penalty as any other late filing.
Mixing up where you fueled vs. where you drove
Fuel purchased at the New Jersey state line counts for the state at the pump, not the state you drove next. This is where shoebox-of-receipts owner-operators most often lose IFTA credits.
Using rate-con planned miles instead of actual driven miles
The rate con says one number. Your actual mileage — including detours, fuel stops off-route, and rerouting around weather — is usually 5-10% higher. IFTA wants what you actually drove.
