Salaried taxpayers get a Rs 50,000 standard deduction. Section 87A rebate makes tax zero up to Rs 5 lakh taxable income. Plus you can claim 80C (Rs 1.5L), 80D, HRA, home loan interest and other deductions.
How the Calculator Works
- Your gross income is reduced by the standard deduction (Rs 75,000 New / Rs 50,000 Old) if you are salaried.
- Under the Old Regime, your declared deductions (80C, 80D, HRA, home loan, NPS, other) are also subtracted to get taxable income.
- Tax is calculated slab-wise on the taxable income.
- The Section 87A rebate is applied if you qualify – tax becomes zero.
- A 4% Health & Education Cess is added to the final tax.
- Both regimes are computed and the calculator tells you which one saves more.
New vs Old Regime – Which Should You Pick?
The New Regime is the default from AY 2024-25 onwards. You can switch to Old at the time of filing if it saves more tax. The Old Regime usually wins only when you have large deductions – heavy 80C investments, HRA from rented housing, a home loan, NPS contribution and health insurance. For most salaried Indians with modest deductions, the New Regime gives lower tax in AY 2026-27 thanks to the wider slab spread and Rs 12 lakh zero-tax threshold.
