New vs Old Regime: Tax Comparison at Common Salary Levels
The table below compares total tax (including 4% cess) assuming ₹1.5L in 80C investments and ₹25K in 80D health insurance for the old regime. New regime figures assume only the ₹75,000 standard deduction.
| Gross Salary | New Regime Tax | Old Regime Tax* | New Saves |
|---|---|---|---|
| ₹10,00,000 | ₹0 | ₹70,200 | ₹70,200 |
| ₹12,75,000 | ₹0 | ₹1,32,600 | ₹1,32,600 |
| ₹15,00,000 | ₹97,500 | ₹2,02,800 | ₹1,05,300 |
| ₹20,00,000 | ₹1,92,400 | ₹3,58,800 | ₹1,66,400 |
* Old regime assumes ₹50K standard deduction + ₹1.5L (80C) + ₹25K (80D) = ₹2.25L total deductions. No HRA or home loan.
Old regime can win if your total deductions (HRA + home loan interest + 80C + 80D) are large. A home loan with ₹2L interest claim plus ₹1.5L 80C plus HRA brings your deductions to ₹5L+ — at that level, old regime becomes competitive for salaries above ₹20L.

Frequently Asked Questions
Q: Which is better — New Regime or Old Regime?
A: The new regime is generally better if your deductions are low. If your Section 80C + 80D + HRA + home loan interest deductions exceed roughly ₹3.75 lakh (for a salary of ₹12L–₹15L), the old regime may save more tax. Use this calculator to compare both for your exact income and deductions.
Q: What is the Section 87A rebate in FY 2025-26?
A: Under the new tax regime, if your taxable income (after standard deduction) is up to ₹12 lakh, you get a Section 87A rebate equal to your entire tax liability (up to ₹60,000). This effectively makes income up to ₹12 lakh tax-free under the new regime. The ₹75,000 standard deduction pushes the effective zero-tax threshold to ₹12.75 lakh.
Q: What is the standard deduction for FY 2025-26?
A: The standard deduction is ₹75,000 under the new tax regime and ₹50,000 under the old tax regime for salaried employees and pensioners. It is automatically applied — no documentation is needed.
Q: Is income up to ₹12.75 lakh really tax-free?
A: Yes, under the new tax regime for FY 2025-26. The ₹75,000 standard deduction reduces gross salary by ₹75,000, and the Section 87A rebate waives tax on the remaining income up to ₹12 lakh. So a gross salary of ₹12,75,000 results in zero tax liability.
Q: Can I switch between Old and New Regime every year?
A: Salaried employees (not having business income) can switch between regimes every year when filing their ITR. Business owners and professionals who have opted out of the new regime cannot switch back easily. It is advisable to calculate your tax under both regimes each year before filing.
