Old vs New Tax Regime FY 2026-27: Which Saves You More?

From FY 2024-25, the new tax regime became the default. If you do nothing, your employer files your taxes under the new regime. But "default" does not mean "better" — for many salaried Indians with HRA, home loans, and 80C investments, the old regime still wins. Here is exactly how to tell.

The Key Difference in One Line

The new regime has lower slab rates but no deductions (no 80C, no HRA, no home loan interest). The old regime has higher slab rates but allows all deductions. Your total deductions determine which is cheaper for you.

Section 87A rebate: Under the new regime, income up to ₹12,00,000 attracts zero tax after the rebate. This is the single biggest advantage of the new regime for incomes below ₹12 lakh.

Under the old regime, Section 87A rebate applies up to ₹5,00,000 taxable income (after deductions), resulting in zero tax. The standard deduction under the old regime is ₹50,000.

With ₹3.5 lakh in deductions, the crossover is around ₹17–18 lakh gross income. Below that, new regime wins. Above it, old regime wins.
