IFTA (Fuel Tax)

International Fuel Tax Agreement:

What It Is:

How It Works:

Buy fuel in various states (pay tax at pump)

Track miles driven in each state

Quarterly: File IFTA report

Calculation: Tax owed per state vs. tax paid

Result: Owe difference or receive refund

IFTA Reporting:

Required Records:

Fuel purchases: State, gallons, price, taxes paid
Miles driven: By state (from ELD or manual logs)

Calculation Example:

Texas: Drove 5,000 mi, tax rate $0.20/gal

- @ 6 MPG = 833 gal owed - Owed: 833 × $0.20 = $166.60 - Paid: (actually purchased 500 gal in TX) 500 × $0.20 = $100 - Owe Texas: $66.60

Missouri: Drove 2,000 mi, tax rate $0.17/gal

- @ 6 MPG = 333 gal owed - Owed: 333 × $0.17 = $56.61 - Paid: (purchased 400 gal in MO) 400 × $0.17 = $68 - Refund from Missouri: $11.39

Deadlines:

Q1: April 30
