How to respond to notification under section 143

If you've received a notification under Section 143(1) of the Income Tax Act, it's likely due to changes in your return, such as not claiming the Section 87A rebate or accrued interest. You can address this by logging into your account and navigating to the 'For your actions' tab on your dashboard. From there, you can file a rectification if necessary, as the Section 87A rebate is auto-calculated.
