Frequently Asked Questions

Mortgage vs take-home planning

Try the Mortgage Calculator and revisit this IL page.

Where do I mail the completed IL-1040-V and payment?

Mail the completed voucher and payment to the address printed on the voucher (Illinois Department of Revenue, Springfield IL 62726-0001) unless told otherwise during filing.

Do charitable gifts affect IL tax?

IL doesn’t mirror federal itemized deductions; charitable gifts matter federally, not typically for IL base.

Why don’t my payroll brackets match?

Employer systems use rounding/timing and supplemental methods; small variances are normal.

Does Illinois tax Social Security or pension income?

No. Illinois exempts most retirement income—including Social Security, pensions, and IRA withdrawals—from state income tax. These subtractions are reported on Schedule M.
