Salaried taxpayers get a Rs 75,000 standard deduction. Section 87A rebate makes tax effectively zero for total income up to Rs 12 lakh (Rs 12.75 lakh for salaried after standard deduction). A 4% Health & Education Cess is added on the final tax.

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.

Quick rule of thumb: If your total old-regime deductions (80C + 80D + HRA + home loan interest + NPS) exceed roughly Rs 4 lakh, the Old Regime usually wins. If they're under Rs 2 lakh, the New Regime almost always wins.

How the Calculator Works

  1. Your gross income is reduced by the standard deduction (Rs 75,000 New / Rs 50,000 Old) if you are salaried.
  2. Under the Old Regime, your declared deductions (80C, 80D, HRA, home loan, NPS, other) are also subtracted to get taxable income.
  3. Tax is calculated slab-wise on the taxable income.
  4. The Section 87A rebate is applied if you qualify – tax becomes zero.
  5. A 4% Health & Education Cess is added to the final tax.
  6. 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.

Frequently Asked Questions

Which tax regime is better for me?
It depends on your deductions. The New Regime has lower slab rates and a Rs 75,000 standard deduction, but no major 80C/80D/HRA benefits. The Old Regime is usually better only if you claim large deductions (e.g. 80C Rs 1.5 lakh + HRA + 80D). For most salaried people with limited deductions, the New Regime gives lower tax in AY 2026-27. Use the calculator above for an exact comparison.
What is the Section 87A rebate in AY 2026-27?
Under the New Regime, full rebate is available so there is effectively zero tax for total income up to Rs 12 lakh (Rs 12.75 lakh for salaried, after the Rs 75,000 standard deduction). Under the Old Regime, rebate is available up to Rs 5 lakh taxable income.
Is the standard deduction available in both regimes?
Yes, salaried taxpayers and pensioners get a standard deduction in both regimes – Rs 75,000 under the New Regime and Rs 50,000 under the Old Regime, for AY 2026-27.
How is total tax calculated?
Tax is computed slab-wise on your taxable income, then a 4% Health and Education Cess is added on the tax amount. If your taxable income is within the 87A rebate limit, the entire tax becomes zero.
Does this calculator include surcharge?
This calculator covers the standard slab tax plus 4% cess and the Section 87A rebate – which covers most salaried Indians. Surcharge applies only above Rs 50 lakh income; very high earners should use the official Income Tax portal at incometax.gov.in to include surcharge.
