Frequently Asked Questions

What is the difference between the Old Regime and New Regime?▾

The Old Regime allows various deductions and exemptions (like 80C, 80D, HRA) but has higher base tax rates. The New Regime (introduced in Budget 2020, revised in 2023 and 2024) offers lower tax rates with more slabs but allows very few deductions — primarily only the standard deduction of Rs 75,000. The best regime depends on how many deductions you can claim under the Old Regime.

What deductions are available under the Old Regime?▾

Under the Old Regime, you can claim Section 80C (up to Rs 1.5 lakh for PPF, ELSS, EPF, life insurance, etc.), Section 80D (medical insurance premiums), HRA exemption, standard deduction of Rs 50,000, Section 80E (education loan interest), Section 80G (donations), home loan interest under Section 24(b), and many other deductions. These deductions can significantly reduce your taxable income.

Who should choose the New Regime?▾

The New Regime is generally better for taxpayers who do not have significant deductions — such as those who don't have HRA, home loan, or major 80C investments. If your total deductions under the Old Regime are less than approximately Rs 3.75 lakh (varies by income level), the New Regime will likely result in lower tax. Use this calculator to compare both regimes with your actual numbers.

How is the Health & Education Cess calculated?▾

Health & Education Cess is calculated at 4% on the total income tax amount (after applying rebate under Section 87A if applicable). For example, if your computed tax is Rs 50,000, the cess would be Rs 2,000 (4% of 50,000), making your total tax Rs 52,000. This cess applies equally under both the Old and New Regimes.

Is rebate under Section 87A applicable?▾

Yes. Under the Old Regime, if your total taxable income is up to Rs 5,00,000, you get a rebate of up to Rs 12,500 — effectively making your tax zero. Under the New Regime (FY 2024-25), if your taxable income is up to Rs 7,00,000, you get a rebate of up to Rs 25,000 — also making your tax zero. The calculator automatically applies this rebate.

Can I switch between Old and New Regime every year?▾

Yes, if you are a salaried individual or pensioner, you can choose between the Old and New Regime every financial year. However, if you have business income, once you opt out of the New Regime, you can switch back only once. The New Regime is the default regime from FY 2023-24 onwards, so you need to specifically opt for the Old Regime if you want those deductions.
