India's Union Budget 2025 made the new tax regime genuinely competitive with — and often superior to — the old regime for a large majority of salaried taxpayers through three landmark changes. This guide explains exactly which regime saves you more money based on your specific income and deduction profile. ## Budget 2025 Key Changes Change 1 — Standard Deduction ₹75,000 (increased from ₹50,000): Every salaried employee gets an additional ₹25,000 deduction under the new regime compared to previous years. Change 2 — Section 87A Rebate Extended to ₹12 Lakh Taxable Income: The 87A rebate (maximum ₹60,000) now eliminates tax completely for taxpayers with taxable income up to ₹12 lakh under the new regime. Combined with the ₹75,000 standard deduction, gross salary up to ₹12,75,000 results in zero tax. Change 3 — Zero Tax Slab Expanded to ₹4 Lakh: Raised from ₹3 lakh, reducing tax on income in the ₹3-4 lakh range. New Regime Slabs FY 2025-26: 0-4L = 0%; 4-8L = 5%; 8-12L = 10%; 12-16L = 15%; 16-20L = 20%; 20-24L = 25%; above 24L = 30%. Plus 4% Health and Education Cess on final tax. ## Old Regime — Deductions Framework Old regime slabs (below 60): 0-2.5L = 0%; 2.5-5L = 5%; 5-10L = 20%; above 10L = 30%. Standard deduction: ₹50,000. Key deductions: HRA exemption (metro: 50% of basic; non-metro: 40%), 80C up to ₹1.5L, 80D health insurance up to ₹25,000, Section 24(b) home loan interest up to ₹2L, NPS 80CCD(1B) up to ₹50,000. 87A rebate: ₹12,500 if taxable income is ₹5 lakh or below. ## The Crossover — When Old Regime Wins Old regime becomes competitive when total eligible deductions exceed approximately ₹3.5-4.0 lakh. Common winning scenarios: home loan borrowers with annual interest above ₹1 lakh + HRA exemption + 80C investments; metro-city rent payers with significant HRA exemption; employees maximizing all deduction categories simultaneously.
