The filing deadline for W-2s and 1099s is February 15

Businesses that issued W-2s or 1099s that contain Iowa withholding must electronically file those documents with the Iowa Department of Revenue. 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.
