Choosing between the New and Old Tax Regimes for Financial Year 2025–26 (Assessment Year 2026–27) is one of the most critical financial decisions salaried employees make. With revised tax slabs, an enhanced standard deduction of ₹75,000 under the New Regime, and full tax rebates up to ₹7 Lakhs of taxable income, the default assumption that the Old Regime saves more tax is no longer true for the vast majority of Indians.

What is the New Tax Regime vs Old Tax Regime in FY 2025–26?

Under FY 2025–26, the New Tax Regime is the statutory default regime featuring concessional slab rates starting from 5% up to 30%, but disallows common exemptions such as Section 80C, 80D, and HRA. The Old Tax Regime maintains higher slab tax rates but permits claiming up to ₹1.5 Lakh under 80C, ₹50,000 under 80D, HRA exemptions under Section 10(13A), and up to ₹2 Lakh home loan interest under Section 24(b).

According to data published by the Central Board of Direct Taxes (incometaxindia.gov.in), over 72% of all individual taxpayers chose the New Tax Regime in the preceding assessment cycle due to its simplified compliance and lower marginal rates.

The Breakeven Deduction Table: When Does the Old Regime Win?

The breakeven point is the exact quantum of deductions you must claim under the Old Tax Regime to pay equal tax to the New Tax Regime. If your total deductible investments and allowances are lower than the breakeven threshold, you will lose money by choosing the Old Regime.

The mathematical breakeven requirements for salaried individuals (factoring in the ₹75,000 New vs ₹50,000 Old standard deduction) are detailed below:

Example Case Study: ₹15 Lakh Gross Salary

Consider an employee in Chennai earning ₹15,00,000:

• Under New Regime: Gross ₹15,00,000 minus ₹75,000 standard deduction equals ₹14,25,000 taxable income. Total tax payable is ₹1,30,000 + 4% cess = ₹1,35,200.
• Under Old Regime with Standard ₹1.5L 80C + ₹25K 80D: Deductions total ₹2,25,000 (including ₹50k standard deduction). Taxable income is ₹12,75,000. Total tax payable is ₹1,95,000 + 4% cess = ₹2,02,800.
• Net Saving: By choosing the New Tax Regime, the employee saves ₹67,600 in direct cash without locking a single rupee into long-term insurance or lock-in schemes!
