The filing deadline for W-2s and 1099s is February 15.
W-2s and 1099s must be filed using GovConnectIowa.
Businesses that issued W-2s or 1099s that contain Iowa withholding must electronically file those documents with the Iowa Department of Revenue using GovConnectIowa. This data is an essential tool the Department uses to increase the accuracy of tax refunds and detect tax refund fraud during the current income tax filing season. If businesses did not withhold any Iowa taxes in 2021, filing is not required.
What Permit Number should you use to file?
All withholding permits are assigned a 9-digit permit number. The Department recommends using the 9-digit permit number when possible. 12-digit numbers were previously assigned to permits issued before November 15, 2021.
The Department accepts both the 12-digit permit number and 9-digit permit number when filing withholding returns, W-2s, and 1099s.
Note: VSPs are filed separately from W-2s and 1099s, and are due to the Department by February 15.
