Illinois offers an "Other Adjustment" only if the IRS instructs you to include an adjustment amount on your Federal return that is not specifically listed on Form 1040, Lines 23-35. This is not a common line item.
- If the federal adjustment is for an item of income (reported on Federal Form 1040, Lines 7-21, you may include a deduction to the extent that the income is included on your Illinois return.
- If the federal adjustment is an expenditure related to income, you may include a deduction to the extent that the related income is taxed in Illinois.
- If the federal adjustment is an expenditure unrelated to income, you may include the amount that you included on your Federal return.
