This discussion clarifies whether deductions under Chapter VI-A can be claimed when filing an Income Tax Return (ITR) late. Initially, there was confusion, with some believing no deductions were possible. However, the consensus is that while certain specific deductions (like 80-IC, 80-ID, 80-IE, 10A, etc.) are disallowed, common deductions such as Section 80C can still be claimed even with a belated return. Filing late does incur penalties, interest, and potential loss of carry-forward benefits for certain losses, but it's generally better than non-compliance.
