Illinois law authorizes the NITA to impose a sales tax throughout the six-county Northeastern Illinois region. The NITA sales tax is collected by the Illinois Department of Revenue and paid to the Treasurer of the State of Illinois to be held in trust for NITA outside of the State treasury. Proceeds from the NITA sales tax are paid directly to NITA monthly.
The sales tax rates imposed by the NITA differ in order to recognize the differing levels of transit service provided in the six-county region. In Cook County NITA imposes a 1.25% sales tax whereas in DuPage, Kane, Lake, McHenry, and Will Counties the rate is .50%.
*New* 2026 0.25% NITA Sales Tax: Authorized by the NITA Act in late 2025, an additional sales tax of 0.25% in all six counties of the NITA region.
