Introduction
Every January, your employer's payroll portal sends a notification asking you to declare your tax regime. Most people click through without actually comparing the two options — and that one click determines how much TDS gets deducted every month for the rest of the financial year. Get it wrong and you're either overpaying throughout the year and waiting for a refund, or underpaying and scrambling in March.
Budget 2025 changed the math significantly: the new regime now offers zero tax up to ₹12.75 lakh. Here's a straight comparison to help you pick the right one for FY 2025-26. Plug your own numbers into our income tax calculator to see the exact difference.

Conclusion
For most people earning under ₹15 LPA, the new regime wins — no investment required, no paperwork, and no tax up to ₹12.75 lakh. Above ₹20 LPA, the answer depends on how aggressively you are using deductions. If you're maxing 80C, claiming HRA, and carrying a home loan, the old regime can still come out ahead by a meaningful margin.
Don't rely on a general rule here — the difference between regimes can be ₹30,000 to ₹80,000 at higher salary levels. Run your actual numbers with our income tax calculator and check our regime comparison tool to find your exact break-even point.
