Tax Planning Insights
• Under New Regime (Budget 2025): If your gross salary is up to ₹12,75,000, your tax is effectively ₹0! The ₹75,000 standard deduction brings taxable income to ₹12,00,000, which receives a 100% tax rebate (up to ₹60,000) under Section 87A.
• For ₹12.00 Lakh Gross Salary: Standard deduction (₹75k) reduces taxable income to ₹11.25 Lakhs, which is well below the ₹12 Lakh threshold—resulting in ZERO tax.
• Marginal Relief Built-In: If your taxable income slightly crosses ₹12 Lakhs (e.g. ₹12.10 Lakhs), Section 87A marginal relief caps your tax so you never pay more than the income earned above ₹12 Lakhs.
• Old Regime Potential: You have unused headroom of ₹25,000 across 80C, 80D, and NPS. Maximizing these could lower your Old Regime tax bill.
• Tipping Point: Under Budget 2025 slabs, the New Tax Regime is mathematically unbeatable for almost anyone earning under ₹12.75 Lakhs without locking any money into 80C schemes. For higher earners (e.g. ₹15–20 Lakhs), Old Regime only beats New Regime if total deductions exceed ~₹4,50,000.
