IL SB2349

Creates a new deduction for Illinois state income tax purposes for unreimbursed home office expenses incurred during taxable years beginning on or after January 1, 2022 that would have been deductible for federal income tax purposes before January 1, 2018.

Allows taxpayers to deduct qualifying home office expenses that are no longer eligible under current federal tax law due to changes in the Tax Cuts and Jobs Act of 2017.

The deduction is added as a subtraction modification (subparagraph II) to the base income calculation for individual taxpayers under Section 203(a)(2) of the Illinois Income Tax Act.

Applies retroactively to tax years beginning on or after January 1, 2022 and is exempt from Section 250 sunset provisions.

Takes effect immediately upon becoming law.
