Pro Tips
- !
Know the Simplified Table
New: 0–3L nil, 3–6L 5%, 6–9L 10%, 9–12L 15%, 12–15L 20%, above 15L 30%. Old: 0–2.5L nil, 2.5–5L 5%, 5–10L 20%, above 10L 30%. Both get 4% cess here.
- !
Big Deductions Favor Old
80C at the full 150k plus HRA usually tips the scales toward the old regime.

No Deductions? Go New
With zero 80C/HRA claims the new regime almost always wins.
Examples
12,00,000 salary with 2,05,000 of deductions
At 12,00,000 gross with 80C 1,50,000 plus 80D 25,000 plus HRA 30,000, the new regime wins by 19,760.
- Taxable new = 12,00,000 - 50,000 = 11,50,000; slab tax = 15,000 + 30,000 + 37,500 = 82,500; plus 4% cess = 85,800.
- Taxable old = 12,00,000 - 50,000 - 1,50,000 - 25,000 - 30,000 = 9,45,000; slab tax = 12,500 + 89,000 = 1,01,500; plus 4% cess = 1,05,560.
- New regime saves 1,05,560 - 85,800 = 19,760 despite full 80C claims.
8,00,000 salary with the same 2,05,000 of deductions
At 8,00,000 gross with identical deductions, the old regime wins by 8,840 — the opposite result.
- Taxable new = 8,00,000 - 50,000 = 7,50,000; slab tax = 15,000 + 15,000 = 30,000; plus 4% cess = 31,200.
- Taxable old = 8,00,000 - 50,000 - 1,50,000 - 25,000 - 30,000 = 5,45,000; slab tax = 12,500 + 9,000 = 21,500; plus 4% cess = 22,360.
- Old regime saves 31,200 - 22,360 = 8,840, showing lower incomes with big deductions still favor old.
