Background: India's two regimes
India offers two personal income tax regimes from which taxpayers can choose annually:
- •Old Regime: Higher tax rates but extensive deductions under sections 80C, 80D, etc.
- •New Regime (introduced FY 2020): Lower tax rates but no deductions (with limited exceptions)
Taxpayers choose which regime applies to their income each financial year.
Old Regime: Deduction-heavy
The old regime allows deductions that reduce taxable income:
- •Section 80C: ₹1,50,000 for life insurance, EPF, PPF, ELSS, education, home loan principal (combined)
- •Section 80D: ₹25,000 for health insurance (₹50,000 if age 60+)
- •Section 24(b): Interest on home loans (unlimited)
- •Section 80CCD(1B): Additional ₹50,000 for NPS
An investor with ₹8,00,000 gross salary and ₹1,50,000 in deductions pays tax on ₹6,50,000 income.
Tax rates (old regime, FY 2024–25):
- •₹0–2.5L: Nil
- •₹2.5L–5L: 5%
- •₹5L–10L: 20%
- •₹10L+: 30%
New Regime: Lower rates, no deductions
Tax rates (new regime, FY 2024–25):
- •₹0–3L: Nil
- •₹3L–6L: 5%
- •₹6L–9L: 10%
- •₹9L–12L: 15%
- •₹12L–15L: 20%
- •₹15L+: 30%
The new regime has no deductions — no 80C benefit, no home loan interest relief. However, the tax brackets are more generous at lower income levels.
Worked example
Scenario: Taxpayer earning ₹9,00,000 with ₹2,00,000 in deductible expenses (home loan interest, PPF, insurance).
Old Regime:
- •Gross income: ₹9,00,000
- •Deductions: −₹2,00,000
- •Taxable income: ₹7,00,000
- •Tax: ₹32,500 (0% on first ₹2.5L, 5% on next ₹2.5L, 20% on next ₹2L)
- •Effective rate: 3.6%
New Regime:
- •Gross income: ₹9,00,000
- •Taxable income: ₹9,00,000 (no deductions)
- •Tax: ₹65,000 (0% on first ₹3L, 5% on next ₹3L, 10% on next ₹3L)
- •Effective rate: 7.2%
In this case, old regime saves ₹32,500 annually. However, if the taxpayer had no deductions, new regime would be equivalent or better.
Choosing: The decision framework
Choose old regime if:
- •You have significant 80C deductions (home loan, PPF, insurance)
- •Your income exceeds ₹10,00,000 (where lower new-regime rates provide less benefit)
- •You are in peak earning years with high tax rates
Choose new regime if:
- •You have minimal deductions
- •Your income is below ₹8,00,000
- •You prefer simplicity and transparency
Many taxpayers recalculate annually because circumstances change (new home loan, children's education ending, salary increases).
Why it matters
Regime choice can save ₹30,000–₹1,00,000+ annually depending on income and deductions. It requires a simple comparison each year.
