What's the difference between the New Regime and Old Regime?
The New Regime (the default since FY 2023-24) uses lower slab rates across seven bands from nil to 30%, a Rs 75,000 standard deduction, and a Section 87A rebate that makes tax nil up to Rs 12,00,000 of taxable income, but it disallows most Chapter VI-A deductions like Section 80C, 80D, and HRA exemption. The Old Regime uses higher slab rates (up to 30% above Rs 10,00,000) and a smaller Rs 50,000 standard deduction and Rs 12,500 rebate cap (nil tax only up to Rs 5,00,000), but lets you claim those deductions. With Rs 0 deductions, the New Regime wins at every income level; the Old Regime only overtakes it once your real 80C/HRA/other claims are large enough.
