  • Electronic Filing:
    To help tax practitioners more easily comply with the electronic filing mandate, the Department has decided to accept part-year/full-year nonresident and reciprocal-state nonresident income-tax returns via 2D barcode or paper format for the 2009 filing season. However, beginning with the 2010 filing season, all IT-40PNR and IT-40RNR returns must be filed electronically. Also, a paid preparer?s client may refuse to allow his or her income-tax return to be filed electronically. In order for the preparer to avoid being penalized for not filing the tax return electronically, a completed Form IN-OPT must be signed by the client, and the paid preparer must keep this form on file for five years.
