WRONG IFSC IN ITR

Hai 

here can be several reasons for it being stuck—from you entering a wrong IFSC code or bank account number to the department not agreeing to your tax calculation or deduction claimed leading to a tax credit mismatch. Wrong bank details entry can be easily corrected online on the I-T website. You just have to update your details via ‘Refund Re-issue Request’ under ‘My Accounts’.

In case of a credit mismatch, you might get a notice (via email) from the department. Here, you might have to file a ‘rectification’. “Rectification under Section 154(1) can be filed for small errors such as mismatch in tax credit, advance tax mismatch, incorrect gender, or additional details not submitted for capital gains at the time of filing return,” says Gupta.

A rectification does not mean you have to re-file your ITR. However, post rectifying a ‘mistake’, if there is a change in income you’ll have to file a revised return. Also, you cannot claim new deductions and exemptions in a rectification request.

But there is no refund

Also no tds and other things

Just a simple itr 4

I am sending a pdf go through of it there is detail view abount rectifications and also presented your query about refund reissues also.

I also think so.

Because ifsc code of obc bank has changed on 1 dec 2020 and many obc bank customer had already filled their returns before 1 dec 2020

So i dont think they all will be required to change ifsc code now
