Does revising your ITR after a refund impact you?

[Saanvi]

I've already received my refund, but I realized I missed the CGAS details on my ITR. Should I file a revised return to be accurate, or will it just raise flags and possibly trigger an audit?

You should definitely go ahead and file a revised ITR. Even though you’ve already received your refund, the law actually allows for corrections under Section 139(5). Adding those missed CGAS details now is a smart move — as long as you do it before December 31, it’s seen as a genuine fix rather than a red flag. Your refund might be adjusted a bit, but it’s worth it to avoid a random notice later on. The tax department actually prefers when people proactively fix their own mistakes.

What should I do in this case: if I file a revised return before December 31 to correct the missing CGAS details in my ITR-2? If I've claimed the Section 54 exemption, will this prevent mismatches with Form 26AS and avoid a notice?
