| No deductions | Only standard ā¹50K | New always wins |
Practical Examples
Example 1: ā¹10 LPA with No Investments
New Regime: ā¹10L ā ā¹75K (standard) = ā¹9.25L taxable. Tax = ā¹0 (5% on ā¹4Lāā¹8L = ā¹20K) + (10% on ā¹8Lāā¹9.25L = ā¹12.5K) = ā¹32,500 ā rebate. Net tax ā ā¹0 (rebate covers it).
Old Regime: ā¹10L ā ā¹50K (standard) = ā¹9.5L taxable. Tax = ā¹12,500 + 20% on ā¹4.5L = ā¹12,500 + ā¹90,000 = ā¹1,02,500. New Regime wins by ā¹1L+.
Example 2: ā¹15 LPA with Full Deductions
New Regime: ā¹15L ā ā¹75K = ā¹14.25L taxable. Tax ā ā¹1,62,500.
Old Regime: ā¹15L ā ā¹50K (std) ā ā¹1.5L (80C) ā ā¹50K (NPS) ā ā¹1.5L (HRA) ā ā¹1.5L (home loan interest) = ā¹9.5L taxable. Tax ā ā¹1,02,500. Old Regime saves ā¹60,000.
Health and Education Cess
A 4% Health and Education Cess is added to your final tax liability in both regimes. So if your computed tax is ā¹1,00,000, you pay ā¹1,04,000 total. Surcharge applies for incomes above ā¹50 lakh (10%), ā¹1 crore (15%), ā¹2 crore (25%), and ā¹5 crore (37% ā capped at 25% for New Regime).
Advance Tax ā Who Needs to Pay?
If your total tax liability exceeds ā¹10,000 in a year, you must pay advance tax in installments: 15% by June 15, 45% by September 15, 75% by December 15, and 100% by March 15. Salaried employees whose employer deducts TDS properly are usually exempt, as TDS covers their liability.
