New vs Old Tax Regime — Which is Better?
The new regime offers lower slab rates but removes most deductions and exemptions. It is simpler and beneficial if your total deductions are low. For FY 2025-26, incomes up to ₹12 lakh attract zero tax under the new regime due to the rebate u/s 87A.
The old regime allows deductions under 80C (up to ₹1.5L), 80D, HRA, home loan interest, and more. It is generally better for taxpayers with large deductions, especially those claiming home loan interest and 80C investments simultaneously.

Frequently Asked Questions
Which tax regime is better — new or old?
It depends on your deductions. If you claim large deductions under 80C, HRA, and home loan interest, the old regime may give you a lower tax liability. If your deductions are small or zero, the new regime is usually better. Use our calculator to compare both.

The standard deduction is ₹50,000 for both the new and old tax regimes for FY 2025-26. It is automatically deducted from your gross salary before tax is computed.
What is the 87A rebate under the new regime for 2025-26?
Under the new regime for FY 2025-26, if your net taxable income is up to ₹12,00,000, you get a full rebate under section 87A — meaning your income tax is nil. For income above ₹12 lakh, tax applies on the entire income as per the slab rates.
What is education cess?

How is monthly TDS calculated?
Monthly TDS is your estimated total annual tax liability divided by 12. Your employer deducts this amount from your monthly salary and deposits it with the government on your behalf.
