Frequently Asked Questions

What if I miss the 31st December belated filing deadline?

If you miss 31st December, you cannot file a normal return. You can only file an Updated Return (ITR-U) under Section 139(8A) within 24 months, which requires paying an additional 25% to 50% tax penalty and does not allow claiming refunds.
