As per law, you must file ( mail) a paper return to the IRS if your e-file was rejected . In that case , errors need to be corrected and a revised tax return in paper form should be mailed.Apart from that , if you’re filing your return after the October deadline , you must file tax return in paper form only as e-filed returns are not accepted after due date of filing .
