DOR > Tax Professionals > Corporate Electronic Filing Corporate Electronic Filing

The Indiana Department of Revenue offers electronic filing (MeF) for the IT-20S. Electronic filing is available for S-corporations and partnerships. The department will expand electronic filing to other corporation types in the future.

The department encourages tax practitioners, S-corporations and partnerships to take advantage of this electronic filing option. Filing electronically provides increased security, simplifies the filing process and allows better filing accuracy. It’s also easier and faster for everyone involved.

The Department of Revenue is in the process of certifying multiple participating IT-20S and IT-65 application vendors. Some are closer to certification than others. Once certified, vendors must then make the product available to clients. At this point, the timeline is controlled by the application vendors. As vendors progress through the certification process for 2016 taxes filed in 2017, the table below will be updated.

Who should tax practitioners and CPAs contact with concerns or problems filing the IT-20S or IT-65?

Tax questions should be referred to the department’s corporate tax information line, (317) 232-0129.

Questions regarding unacknowledged and rejected returns should be directed to the practitioner’s transmitter. If the transmitter is not able to resolve an issue with a rejected return, practitioners and CPAs may contact the electronic filing coordinator.

What should tax practitioners and CPAs do with the forms they usually mail to the department?

Taxpayers and preparers should retain copies of the forms they would have submitted to the department if filing by paper. They should be kept with the Declaration of Electronic Filing for the three year retention period detailed on that form. In some cases, the department will request supporting documentation for an electronic return.

What is the grace period for rejected filings?

There is a five calendar day perfection period. During that time, if a rejected return is resubmitted and accepted, the postmark of the original return will be used.
