I have 4 days left before the proceeding limitation date. Why am I unable to submit my response?

Ans.  If your proceeding status is open, the submit response option will be available only till 7 days prior to the proceeding limitation date till 6 PM. If there is no proceeding limitation date, the Income Tax Authority can close the e-submission option. However, at the option of the Income Tax Authority, the submission window can be re-enabled till the proceeding limitation date.​​
