Who must file Form IL-941?

You must file Form IL-941 if you paid amounts subject to Illinois withholding income tax (either required or by voluntary

agreement), such as:

•

Wages and other employee compensation including bonus, overtime, and commission pay, usually reported to the recipient

on a Form W-2.

•

Non-wage income such as pensions, annuities, unemployment income, and sick pay for which you have voluntarily agreed

to withhold Illinois taxes, usually reported to a recipient on a Form 1099.

•

Gambling and lottery winnings (paid by the entity issuing the winnings such as the Illinois Lottery or a casino), usually

reported to a recipient on a Form W-2G.

•

Amounts paid to purchase rights to Illinois lottery winnings reported on a Form 1099-MISC.
