Every financial year, salaried Indians face a critical choice: stick with the Old Tax Regime and claim every possible deduction, or opt for the New Tax Regime's lower slab rates without investment mandates. For FY 2025-26, the New Regime is the default, and it is genuinely better for many taxpayers — but not all.
This article provides the complete break-even analysis: at what deduction level does the Old Regime win? What are the exact numbers? And how do you decide quickly without a CA?
New Regime Slabs for FY 2025-26
After the ₹75,000 standard deduction: up to ₹3L — nil; ₹3L–₹7L — 5%; ₹7L–₹10L — 10%; ₹10L–₹12L — 15%; ₹12L–₹15L — 20%; above ₹15L — 30%. A 4% Health and Education Cess applies on all tax.
87A rebate: if taxable income (after ₹75,000 standard deduction) is ₹7 lakh or below, your tax is zero. This means gross income up to ₹7.75 lakh is completely tax-free. Marginal relief prevents tax from exceeding the excess income above ₹7.75L.
Old Regime Slabs and Deductions
After ₹50,000 standard deduction: up to ₹2.5L — nil; ₹2.5L–₹5L — 5%; ₹5L–₹10L — 20%; above ₹10L — 30%. 87A rebate if taxable income ≤ ₹5L.
Key deductions: 80C (₹1.5L — EPF, PPF, ELSS, LIC, home loan principal), 80D (₹25K health insurance; ₹50K if senior parent), HRA exemption (40–50% of basic if paying rent), Section 24 (₹2L home loan interest), 80CCD(1B) (₹50K NPS).
The Old Regime makes sense only if you can claim substantial deductions — typically ₹2.5–5L total depending on your income level.
Break-Even: When Does the Old Regime Win?
The break-even is the total deduction amount at which both regimes produce identical tax. Below this, New Regime wins; above it, Old Regime wins.
At ₹8L income: Old Regime wins if deductions exceed ~₹1.5–1.75L. At ₹12L: break-even ~₹2.5L. At ₹18L: ~₹3.5–4L needed. At ₹25L: ~₹4.5–5L needed.
Practical reading: an employee with only EPF (auto-deducted), no home loan, no metro-city rent, and modest savings → New Regime is better. An employee with a home loan, metro rent, PPF, ELSS, and health insurance for parents → Old Regime likely wins above ₹12L CTC.

Switching Between Regimes
Inform your employer at the start of April. Your employer needs your regime choice to calculate TDS monthly. Salaried individuals (no business income) can switch every year at ITR filing time.
If planning a home loan in 2–3 years, the Old Regime may become more attractive then. Don't optimise purely for today's situation.
