Electronic filing methods for Forms W-2 and W-2c

Electronic filing of Forms W-2 and W-2C is mandatory. The Illinois Department of Revenue does not accept Forms W-2 and W-2cs that are submitted to us by mail. Payroll providers and employers must electronically submit Forms W-2 and W-2c using one of the following methods:

Filing Deadline: Forms W-2 for tax year 2019 are due on or before January 31, 2020. We adjust due dates that fall on a weekend or state-recognized holiday to the next business day. If the IRS has granted you an extension of time to file a federal information return due to a natural disaster or other approved reason, you must submit copies of your Forms W-2 to the Illinois Department of Revenue on or before the extended due date of the federal information return. We will not penalize taxpayers that have been granted a federal extension for information returns due on or before January 31 and if you file your Forms W-2 with us on or before the federal extended due date. We will not penalize businesses that make a reasonable and good faith effort to comply with the deadline.
