Maximising Section 80C and Beyond for Tax Year 2025-26
The OLD regime continues to offer the deepest deduction architecture in Indian tax. While Finance Act, 2023 made the new regime the default, salaried taxpayers can still elect the old regime annually via Form 10-IEA -- and for those with significant section 80C / 80D / House Rent Allowance / home loan / 80E investments, the savings can be substantial.
