I am an employer. Must I submit my employees' Forms W-2, W-2c, W-2G, and 1099 to IDOR electronically?

Forms W-2, W-2c, and W-2G are required to be electronically filed with Illinois. Forms 1099 are not included in the electronic filing mandate or required to be submitted to Illinois, unless we request them. Payers who issue Forms 1099, which report Illinois income tax withheld, may voluntarily file these forms electronically through the Illinois FIRE Electronic Transmittal Program or through MyTax Illinois. We do not accept W-2s and 1099s submitted by mail.
