New Jersey IFTA fuel tax rate, Q4 2026

What you owe New Jersey

IFTA apportions your fuel by miles. Divide total miles by total gallons for fleet MPG, turn your New Jersey miles into taxable gallons, subtract the tax-paid gallons you bought in New Jersey, and multiply by $0.5610.

Example: 1,000 miles in New Jersey at 6.5 MPG is 153.85 taxable gallons. With 100 tax-paid gallons bought there, 53.85 × $0.5610 = $30.21 owed to New Jersey.

This rate is for diesel, Q4 2026. You still file with your base jurisdiction; keep your trip records and receipts.
