Why Am I Required to File Electronically?
Any business who files more than 25 W-2, W-2G, or 1099-R statements must file them electronically (IC 6-3-4-16.5).
What Do I Do Next?
If your withholding file size is 10MB or less you’ll manually enter or batch upload via INTIME. If your withholding file size is 10MB or over, you will batch load your W-2s using the bulk upload SFTP. For more information about both methods of submitting WH-3s, see the Bulk Upload Guide.
The bulk upload facility provides taxpayers submitting files with large numbers of transactions the ability to electronically submit these records to the Indiana Department of Revenue (DOR). Bulk upload is available for the following tax types: gasoline use tax, alcohol tax, motor vehicle rental, cigarette tax, other tobacco product tax and withholding.
What’s a WH-3?
The WH-3 (Annual Withholding Reconciliation Form) is a reconciliation form for the amount of state and county income taxes withheld throughout the year. All employers must file the WH-3 by January 31 each year. If you previously registered to file withholding tax, you must still file Forms WH-1 and WH-3 for each period even if no tax is due or to report no employees for that time period. Late filed WH-1 returns are subject to a penalty of up to 20%, and a minimum penalty of $5. Late filed WH-3's are subject to a penalty of $10 per withholding document (W-2, 1099, K-1).
There are now two options for a WH-3 bulk upload file submission:
- Submission of less than 10MB should be uploaded directly through INTIME (Indiana Tax Information Management Engine)
- Submission larger than 10MB must be uploaded via Bulk SFTP (Secure File Transfer Protocol). WH-1 and MVR-103 returns can be filed via bulk SFTP (Secure File Transfer Protocol) upload only. There is no size limitation to file with the SFTP.
Both XML and flat file formats are accepted:
- XML file formats are accepted for WH-3, WH-1, and MVR-103 tax returns.
- Flat file formats are accepted for wage statements.
Bulk upload files are created offline and then submitted to DOR for processing. The files are processed sequentially within a couple of hours. During high-volume processing, the delay can be longer. When the process is complete, an acknowledgment email is sent to the authorized representative with the results of the submission.
