Submitting files

Iowa accepts electronic filing for current year and three Prior year filings.
Corrected W-2's can be submitted as a new original W-2. The state does not accept the W-2C for corrections.

Submit a W-2 file containing all W-2's not just the updated information. Please see: W-2 corrections as new original file.

The Department accepts both the 12-digit permit number and 9-digit permit number when filing withholding returns, W-2s, and 1099s.

If businesses did not withhold any Iowa taxes, filing is not required.

Iowa supports bulk filing for W-2s and 1099s. The customer must be a registered (approved) bulk filer with the Iowa Department of Revenue in order to have the bulk filing option. A transmitter must use its own login information to access GovConnectIowa as a Bulk Filer, just as Payroll Service Providers do. Transmitters must register with the Iowa Department of Revenue in order to become an Iowa GovConnectIowa Bulk Filer. 

Log in: Go to GovConnectIowa. Log in using the same credentials that you use to file your Iowa withholding tax return. 

Upload: Select Submit W-2s and 1099s. Only taxpayers with a withholding permit and bulk filers have this option. 

Check Results: Results will immediately be displayed. Errors will need to be corrected prior to getting a successful submission. 

For each file Iowa receives, Iowa posts a confirmation number. If there are issues with your data, the errors will report why your file (or parts of it) was rejected; error messages will be listed accordingly. You will need to correct the errors prior to getting a confirmed submission. 

Corrected

Users are not bound to the original filing method when filing corrected forms. Submit corrected information via file upload or manual key. Follow the same steps as you would if you were filing original information.

The Department will always use the last uploaded file or manual key submission for data purposes. Duplicate W-2 and 1099 forms will be discarded.

Send another original and replace the first original. Make your corrections on the form. On Step 5 reset the original file and create a new original on Step 4.

You may submit the corrected information via file upload or manual key submission. An additional step is needed to correct information submitted under the wrong SSN/ITIN.

1. Submit a file or manual key submission listing employee/payee information at $0 under the incorrect SSN or ITIN. (This clears out incorrect wages or withholding under the incorrect SSN or ITIN)

2. Submit a file or manual key submission with the correct employee/payee information, under the correct SSN or ITIN.
