Notes from the source

Matrix footnote #18 (FLORIDA): Effective July 1, 2018, the current exemption of natural gas fuel (LNG and CNG) from the taxes imposed by Chapters 206 and 212, F.S., was extended through December 31, 2022. Governor Ron DeSantis has signed into law (HB 7071) a one-month Fuel Tax Holiday. All motor carriers who are licensed with the International Fuel Tax Association (IFTA), traveling in Florida, and purchasing gasoline products will see a reduced tax rate from October 1, 2022, through October 31, 2022. The reduced tax rate does not apply to Diesel. IFTA returns are still required to be filed for the quarter that includes this Tax Holiday. All miles traveled and fuel purchases must be reported on IFTA returns to accurately reflect miles per gallon (MPG) for the period. Between October 1 and October 31, 2022, Gasoline and Gasohol filers should report all total/taxable miles traveled and tax paid fuel gallons purchased in Florida for the Tax Holiday. Please use the following instructions below for reporting activity from October 1, 2022, through October 31, 2022: There will be a split tax rate for the 4th quarter of 2022 for Gasoline and Gasohol- FL will be used for the correct tax rate for 10/01/2022 – 10/31/2022 FL1 will be used for the correct tax rate for 11/01/2022 – 12/31/2022

On an IFTA return, a higher rate doesn't mean you pay more overall. Fuel you buy in a high-rate state earns a bigger credit. What matters is where you burn the fuel versus where you buy it.
