Important Notice:

Effective April 1, 2024 – Update to the IFTA Reporting Penalty Calculation per the Articles of Agreement Assessment and Collection. 

The update removes the Arizona $0.02 credit from the calculation.  The calculation (Total Taxes Due x 10% = Updated Penalty) updates the Penalty based on Total Taxes Due.  Please update your applications/programs used to process your IFTA Quarterly reports.

*R1220 PENALTIES, section .100 states, “The base jurisdiction may assess the licensee a penalty of $50.00 or 10 percent of delinquent taxes, whichever is greater, for failing to file a tax return, filing a late tax return, underpaying taxes due."
