Motor Fuel Tax
The City of Naperville collects a Local Gas Tax at the rate of four-cents ($0.04) per gallon.
Monies from the Local Gas Tax are allocated to the Road and Bridge Fund.
- Revenues from the Local Gas Tax are approximately $2.6 million annually.
- This tax helps fund the annual Maintenance Improvement Program (MIP) street resurfacing/reconstruction program.
All retailers must fill out and return a Motor Fuel Tax Registration Form.
The Motor Fuel Tax is due monthly. Payment of the tax must be made to the City of Naperville no later than the 20th of each month following the month in which the tax was collected. For example, taxes collected during the month of July are due no later than August 20. Along with the tax payment, business owners must submit a completed Motor Fuel Tax Return Form and a copy of either the Illinois Department of Revenue Sales and Use Tax Return Form (ST-1), or the County Motor Fuel Tax form (CMFT-1/CMFT-2), or an internal report.
Filing after the due date will result in a Late Payment Penalty equal to 5% of the unpaid tax and an Interest Penalty equal to 1.5% of the unpaid tax per month.
