Regsrding Rectification

Pls download your ITR-V n check that it's invalidated or not?
Check the status of return at incometaxefiling website,
is there any defective notice issued?
or any rectification link is available or any others info at return filing status.

Yes sir, it is invalidated. And got the mail from dept. stating that your return is invalidated. No rectification link is available. Rectification time is lapsed it seems. What should be done sir?

I had called the dept. they are telling to file fresh return. Sir my question is should i pay interest from original filing date to current date? Or only till original filing date? (where i paid while filing original return)

If you are filing a fresh return than you are required to pay interest till current filing date.
But according to me it's not justified to invalidated return completely just due to spelling mistake of name as per ITR and CBDT database.
