Enter one row per jurisdiction you drove in this quarter. Taxable miles start equal to total miles; change them if some miles were exempt (toll roads, off-road, etc., per that jurisdiction's rules). Enter the tax-paid gallons you bought there and the tax rate per gallon from the official IFTA Tax Rate Matrix for the quarter you're filing.
| Jurisdiction | Total miles | Taxable miles | Tax-paid gallons | Rate ($/gal) |

Read before you file
- Surcharges: some jurisdictions (for example Kentucky, Indiana and Virginia) add a surcharge on top of the base rate, reported as a separate line. Check the IFTA Tax Rate Matrix and add those lines yourself.
- Canadian provinces: rates are set per litre in Canadian dollars. The matrix shows the converted U.S. $/gallon rate; use that one here.
- Rates change every quarter, and fuel types (diesel, gasoline, etc.) have different rates. File through your base jurisdiction.
- Rounding here is to 2 decimals; your base jurisdiction's return may round differently.
