IFTA HQ is an independent tool. It is not affiliated with, endorsed by, or operated by IFTA, Inc., the International Fuel Tax Association, or any state, provincial, or federal government agency.

This calculator produces an estimate to help you prepare your quarterly IFTA return. It is not tax, legal, or accounting advice, and it does not file anything on your behalf. You are responsible for the figures you report to your base jurisdiction.

Tax rates are compiled from publicly available official sources for the quarter shown, together with the date we retrieved them. Rates can be corrected or amended after publication. Always confirm the rates against your base jurisdiction's official return before filing.

An IFTA audit is decided on your source records: trip reports, distance records, and fuel receipts. A worksheet from this site documents how the numbers were calculated. It does not replace those records.

Some links on this site are affiliate links. If you sign up through them, we may earn a commission at no extra cost to you. This never changes how your tax is calculated.
