Indiana Form IN-OPT is an Indiana Electronic Filing Opt-Out Declaration used by individuals who do not wish to have their tax returns filed electronically by their paid preparer. This form is necessary for clients who refuse to allow their professional tax preparer to submit their 2025 Indiana individual income tax return electronically, as required by the state’s e-filing mandate. According to the mandate, professional preparers who file more than 10 individual income tax returns in a calendar year must file subsequent returns electronically. However, clients can opt out of this electronic filing requirement by completing and signing Form IN-OPT, which the paid preparer must retain for their records. This form ensures that no penalty is imposed for not filing the return electronically. It must not be mailed to the Indiana Department of Revenue but kept on file by the preparer for five years.
