Illinois recently passed legislation that allows a taxpayer to deduct a percentage of Illinois taxes, known as the pass-through entity tax, on the federal return (1120-S in this instance).

However, from what I understand, this amount cannot be deducted on the IL-1120ST state return.

How should this tax be entered in ProSeries to ensure it flows properly?
