The Illinois Department of Revenue mandates the filing of the W2 Forms only if there is a state tax withholding. TaxBandits supports the filing of Form W-2 with both the Federal and State of Illinois.
What to be filed
The filing due date for both Form W2 and IL-941 with Illinois is January 31.
The penalty of $250 or 2% of your unpaid taxes will be imposed on you for each Form W2 not filed on time with the state of Illinois.
