In the meantime, please note that the IRS has not provided any indication that the current testing session will be extended. Given this, any files that are not re-submitted or processed prior to the end of the current session (5PM EST, June 30th) will not be returning a Notification response. After the close of testing, the only remaining option will be to prepare and submit Real Data files via the Production environment. Our Help Desk is prepared to assist with any errors encountered in Production.
