Aviation Fuel Tax


A portion of State sales tax on aviation fuel is subject to the Federal Aviation Administration (FAA) revenue-use requirement. To comply with the FAA’s Policy Concerning the Use of Airport Revenues; Proceeds from Taxes on Aviation Fuel, the State Aviation Program Fund and Aviation Fuel Sales Tax Refund Fund were created under 30 ILCS 105/6z-20.1 and 30 ILCS 105/6z-20.3, respectively. The moneys shall be used for the purpose of distributing grants to units of local government to be used for airport-related purposes.

Per the FAA, under this program, the granted funds are “considered to be airport revenue and subject to the revenue-use requirement. Airport revenues can only be expended for the capital or operating costs of the airport; the local airport system; or other local facilities owned or operated by the airport owner or operator and directly and substantially related to the air transportation of passengers or property.

Additionally, FAA’s Airport Compliance Manual – Order 5190.6B – Change 3 can be utilized to provide additional informal on airport revenue use requirements. Such costs can only be paid for once and not previously requested under other programs.


Subject to appropriation, funds will be distributed based on a mandated formula. In summary, the funds are first divided in three equal parts corresponding to enplanements, total cargo and airport operations, and then distributed proportionally to each airport with recorded activity in these categories. The total fund amount will vary from year to year based on the amount of tax revenue collected.

Statute 30 ILCS 105/6z-20.1 does not dictate data sources or data dates, however airport operations and air traffic data is obtained from public facing FAA websites.  Data is collected for a full calendar year and is available at the end of the Federal fiscal year.  This data is used in the calculations for the next full State fiscal year (i.e., calendar year 2021 data determines fiscal year 2023 allocations).


Eligible applicants are public-use public-owned airports in Illinois.

Recipients of grants are referred to as "Sponsors". Sponsors must be legally, financially and otherwise able to carry out State and Federal grant assurances and obligations contained in the project application and grant agreement, including the ability to meet and comply with the Grant Accountability and Transparency Act (GATA).
