Resources for Bulk Filing your Indiana Taxes

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.

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.

Withholding Schemas for WH-1 & WH-3

DOR has XML schemas to service WH-1 and WH-3 filings.

Effective January 1, 2017, the following schema, IDORWTH2016V1.0, must be used for all filing years. If the SFTP Bulk Filing process is used, the WH-1 must be submitted in XML format.
