Forgot to pay self assessment tax before filing ITR

If you've filed your Income Tax Return (ITR) without paying the self-assessment tax, don't worry. You can still rectify the mistake by obtaining a challan and submitting a revised return. Alternatively, if your ITR has already been processed and a demand has been raised, you can pay the tax directly through the e-filing portal and then file a revised return immediately. This can be done even after receiving the ITR intimation.
