Pennsylvania IFTA Reporting Requirements

Pennsylvania IFTA at a glance

Pennsylvania's current diesel fuel tax rate is $0.741/gallon, and the jurisdiction requires electronic filing of quarterly IFTA returns. You file directly with the state agency at the official Pennsylvania IFTA portal.

Pennsylvania follows the standard IFTA quarterly deadlines: April 30 for Q1, July 31 for Q2, October 31 for Q3, and January 31 for Q4 (filing for the prior calendar quarter). Late filing typically triggers a penalty of the greater of $50 or 10% of net tax liability, plus interest accrued from the original due date.

What to know about IFTA in Pennsylvania

Pennsylvania's $0.741/gallon diesel tax is the second-highest in the United States, reflecting decades of dedicated funding for bridge and highway maintenance through the state's Liquid Fuels Tax. Pennsylvania's geographic position between New York, New Jersey, Ohio, and the I-95 corridor makes it one of the most heavily traveled IFTA states — most northeast freight passes through PA at least once per trip.

IFTA returns are filed electronically through the Pennsylvania Department of Revenue's myPATH system. New carriers must apply for an IFTA license through PennDOT before operating; decals are valid for the calendar year and must be renewed by December 31. Pennsylvania follows the standard quarterly deadlines.

The high tax rate means under-reported Pennsylvania miles can quickly add up to material assessments. Carriers should pay attention to the Pennsylvania Turnpike's mile-by-mile toll data, which auditors can subpoena to compare against reported IFTA miles. Keep fuel receipts (cardlock, retail, and bulk) for at least four years, and reconcile your reported miles against E-ZPass or other electronic toll records — discrepancies of more than 5% on PA-only miles are a common audit trigger.

Who needs a Pennsylvania IFTA license?

You need a Pennsylvania IFTA license if you operate in Pennsylvania and at least one other IFTA jurisdiction with vehicles that are:

• Three or more axles (any weight)
• Over 26,000 lbs. gross or registered weight
• Combined weight over 26,000 lbs.

Your IFTA license and decals are issued by your base jurisdiction — for Pennsylvania-based carriers, that means filing with the state revenue or transportation department listed above. All quarterly returns flow through that single base-jurisdiction filing, even when miles were driven across multiple states or provinces.

Who needs to file Pennsylvania IFTA taxes?

All license holders must file quarterly IFTA tax returns, even if no miles were traveled.

Note: Licenses remain active until officially closed.

What happens if you file IFTA incorrectly?

What are you risking by submitting an inaccurate IFTA filing? Even small discrepancies in reported miles or fuel can lead to:

• Costly fines and back taxes
• Delays with renewals or suspended accounts
• Failed audits and penalties

Why do errors happen?

• Mileage and fuel data accumulate quickly — it’s tough to catch every issue. Records often go unnoticed until it’s too late.
• Carriers often depend entirely on ELD IFTA reports, thinking they’re complete — but there’s no way to verify them.
• Fuel card reports may exclude cash purchases or missing transactions.
