529 deduction: YesTax parity: No — Illinois plans only
In-state plans only
Most states that offer a 529 tax break only give it for their own in-state plan, and Illinois follows that rule: the deduction applies only to the Illinois-sponsored plans — Bright Start, Bright Directions, and College Illinois. Contributions to another state's 529 get no Illinois deduction. Only nine "tax-parity" states let you deduct contributions to any state's plan, and Illinois is not among them.
The deduction
As of recent guidance, Illinois taxpayers can deduct up to $10,000 per year ($20,000 for married couples filing jointly) in total, combined contributions to the Illinois plans. The cap applies to the return as a whole, not per beneficiary, and unused amounts do not carry forward. Deductions already taken are added back to Illinois income if the money later comes out in a nonqualified withdrawal or rolls over to a non-Illinois plan. Limits change yearly — confirm the current figure with the Illinois plans.
How it fits with the gift-tax rules
A 529 contribution is also a gift for federal purposes, so it counts toward the $19,000 annual exclusion (2026). The 5-year election ("superfunding") lets you front-load up to $95,000 per donor per child without using any lifetime exemption.
