How the Massachusetts rate is used on your IFTA return
For each state the return takes the miles you drove there, divides by your fleet MPG to get taxable gallons, multiplies by the state rate, then subtracts the tax you already paid on gallons bought in that state. With the Q4 2026 Massachusetts rate:
- 10,000 miles in Massachusetts ÷ 6.5 MPG = 1,538 taxable gallons
- 1,538 gal × $0.24 = $369.12 tax
- 1,000 gal bought in Massachusetts × $0.24 = $240.00 credit
- Net for Massachusetts: $129.12 owed
Your base state nets every state’s line into one payment or refund. This is a reference, not filing advice; verify with your base jurisdiction.
