Form IFTA-100, IFTA Quarterly Fuel Use Tax Return

Beginning with the first quarter 2024 IFTA filing, due April 30, 2024, you cannot use IFTA Web File if you are reporting travel by electric or hydrogen-powered qualified motor vehicles in the state of Indiana, a jurisdiction that calculates fuel use tax based on taxable distance traveled.

Instead, you must file Form IFTA-100, IFTA Quarterly Fuel Use Tax Return and Form IFTA-101, IFTA Quarterly Fuel Use Tax Schedule, using paper. Contact us if you need help calculating your tax due using the taxable distance method on your IFTA return.
