New vs old tax regime — which one saves you more money in 2024–25

Lower rates vs more deductions. The right answer depends entirely on your numbers. Here is the exact calculation — with a break-even point that tells you which regime wins.

Key takeaways
New regime: lower rates but no deductions — no 80C, HRA, home loan interest
Old regime: higher rates but deductions can significantly reduce taxable income
Break-even: if your total deductions exceed ~₹3.75 lakh, old regime is better
From FY2023-24, new regime is the default — opt for old regime explicitly
Calculate both every April before declaring to your employer

Side-by-side: ₹12 lakh income, both regimes
OLD REGIME: Gross: ₹12,00,000 Minus standard deduction (₹50,000): ₹11,50,000 Minus 80C (₹1,50,000): ₹10,00,000 Minus 80D health insurance (₹25,000): ₹9,75,000 Minus NPS 80CCD (₹50,000): ₹9,25,000 Taxable income: ₹9,25,000 Tax: ~₹1,05,000 NEW REGIME: Gross: ₹12,00,000 Minus standard deduction (₹75,000): ₹11,25,000 No other deductions Taxable income: ₹11,25,000 Tax: ~₹1,30,000 Old regime saves ₹25,000 in this scenario. Add HRA exemption if paying rent and the advantage grows.

The practical decision — 3 steps every April
Step 1: List all deductions you actually have: • Standard deduction: ₹50,000 (old) or ₹75,000 (new) • 80C (EPF + investments): how much? • 80D (health insurance): how much? • HRA (if paying rent): calculated amount • Home loan interest (80EEA): if applicable • NPS 80CCD(1B): ₹50,000 if contributed Step 2: Use the free IT Department calculator at incometax.gov.in → Tax Calculator. Enter your numbers in both regimes. Step 3: Choose the lower tax option. Declare this to HR before April 30 for correct TDS.
