The 2019 W-2s are due on or before January 31, 2020. Any time a due date falls on a weekend or state recognized holiday, we adjust the due date to the next business day. If the IRS has granted an extension of time to file a federal information return due to a natural disaster or other approved reasons, an employer must submit copies of its W-2s to the Illinois Department of Revenue on or before the extended due date of the federal information return. Taxpayers who are granted a federal extension for information returns due on or before January 31 and who file their W-2 information with us on or before the federal extended due date will not be penalized. Businesses that make a reasonable and good faith effort to comply with the deadline will not be penalized.
