Old vs New Tax Regime 2025-26: Which Should You Choose?
The new tax regime is now the default for FY 2025-26 — but that doesn't mean it's automatically better for you. This guide gives you the tools to compare both regimes with real numbers so you can make an informed choice before filing.

Key Differences at a Glance
The core trade-off is simple: the new regime offers lower tax rates but removes most deductions and exemptions. The old regime has higher rates but lets you claim deductions that can substantially reduce your taxable income.
Under the new regime, there is no benefit for HRA, home loan interest, 80C investments, or 80D health insurance. What you get is a standard deduction of ₹75,000 and a zero-tax threshold of ₹12 lakh (via Section 87A rebate).

Break-Even Deduction Analysis
The new regime wins when your deductions are small. The old regime wins when your deductions are large. The break-even point — where both regimes produce the same tax — depends on your income:
- At ₹10 lakh gross: The new regime is almost always better (the zero-tax benefit is hard to beat with deductions alone).
- At ₹15 lakh gross: Old regime wins if total deductions exceed approximately ₹3.25 lakh.
- At ₹20 lakh gross: Old regime wins if total deductions exceed approximately ₹4 lakh.
- At ₹30 lakh gross: Old regime wins if total deductions exceed approximately ₹4.75 lakh.
Examples for Different Salary Levels
Example 1: ₹12 lakh gross salary
New regime taxable income: ₹12L − ₹75,000 (standard deduction) = ₹11.25L. Tax before rebate: ₹1,12,500. After 87A rebate (applicable since taxable income ≤ ₹12L): ₹0 tax payable.
Old regime: Even with ₹2.5 lakh in 80C + 80D deductions, tax payable would be around ₹65,000. The new regime clearly wins here.
Example 2: ₹20 lakh gross salary
Assume deductions: 80C ₹1.5L + HRA ₹1.2L + 80D ₹25K = ₹2.95L total.
New regime tax: ~₹2,73,000. Old regime tax: ~₹2,46,000. Old regime saves ~₹27,000 in this case.
Example 3: ₹35 lakh gross salary
With maximum deductions (80C ₹1.5L + HRA ₹1.8L + 80D ₹50K + home loan ₹2L = ₹5.8L), old regime tax is ~₹7.3L vs new regime ~₹8.5L. Old regime saves ~₹1.2 lakh.
Who Benefits from Each Regime
New regime is better if you:Earn below ₹12.75 lakh, live in employer-provided accommodation (no HRA), don't have a home loan, invest minimally in 80C instruments, or want a simpler filing experience.
Old regime is better if you: Pay significant rent in a metro city, have a home loan, consistently max out 80C, have family health insurance premiums, or have NPS contributions under 80CCD(1B).
How to Switch Regimes
Salaried employees can switch regimes every year. You indicate your choice to your employer at the start of the financial year for TDS purposes, and you can make a final choice when filing your ITR. Business/professional taxpayers can switch from old to new only once.
