Indiana Online Filing Information for Developers

The Indiana Department of Revenue (DOR) is looking for certified software companies who wish to provide Federal/State Online tax filing for Indiana taxpayers.

If you plan to develop software for electronically filing Indiana Individual Income Tax Returns and also plan to offer that software to the public to file via the Online Filing Program, please contact us immediately. You will need to be accepted by the IRS and your software will need to be tested by DOR. This includes testing of certain forms the software must produce.

Once you have been certified for the tax year (after the testing process) and upon request from you, we will place your web link on our web page.

If you have any questions, please contact: Alternative Filing Manager
