Local Gas 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. The tax helps fund the City’s annual street resurfacing and reconstruction program.
All businesses must submit a local tax registration form electronically via the Help Center on the City's website.
After the registration is submitted, Finance staff will provide the business with a customer ID and business account, which the business will use to create an account in the City’s Citizen Self Service (CSS) portal to file their tax electronically.
Filing and Payment
The Local Gas Tax is due monthly. Taxes must be filed, and payment 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 20th.
As part of the filing, business owners must attach 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 sales report.
There is a one percent (1%) penalty for filing or making payment after the due date.
To file, go to the City of Naperville Citizen Self Service (CSS) portal.
