  • Health & Education Cess: 4% on (Tax + Surcharge)
  • Marginal Relief: If your income just crosses a threshold, tax is capped so you don't pay more than the excess income

How This Calculator Works

This calculator compares your tax liability under both regimes for FY 2025-26. Here is what it accounts for:

  • Old Regime: Standard deduction (Rs 50,000) + all eligible deductions (80C, 80D, HRA, home loan, NPS)
  • New Regime: Only standard deduction (Rs 75,000) and employer NPS 80CCD(2). No other deductions allowed
  • Rebate u/s 87A: Full rebate in new regime up to Rs 12L taxable income; Rs 12,500 in old regime up to Rs 5L
  • Surcharge: Applied for taxable income above Rs 50L with marginal relief at threshold crossings
  • Cess: 4% Health & Education Cess on total tax + surcharge
Tax Calculation Steps:
1. Gross Income - Deductions = Taxable Income
2. Apply slab rates to get base tax
3. Apply rebate u/s 87A (if eligible)
4. Add surcharge (if applicable) with marginal relief
5. Add 4% Health & Education Cess
6. Apply marginal relief (if income near threshold)

Frequently Asked Questions

For FY 2025-26, the new regime is better for most taxpayers due to lower rates and Rs 12L rebate limit. Old regime may be better only if your total deductions (80C, 80D, HRA, home loan interest) exceed Rs 4-5 lakhs.
Standard deduction is a flat deduction from salary income. It is Rs 75,000 in the new regime (FY 2025-26) and Rs 50,000 in the old regime. No bills or proof required.
In the new regime, if your taxable income is up to Rs 12,00,000, you get a full rebate and pay zero tax. In the old regime, the rebate is up to Rs 12,500 if taxable income is up to Rs 5,00,000.
Marginal relief ensures that if your income slightly exceeds a threshold (like Rs 12L for rebate or Rs 50L for surcharge), your total tax does not exceed the excess income. This prevents unfair taxation at threshold crossings.
Salaried employees can switch regimes every year while filing ITR. Business owners can switch only once in their lifetime. The new regime is the default from FY 2023-24.
Yes, employer's NPS contribution under Section 80CCD(2) is allowed in both regimes. However, your own NPS contribution under 80CCD(1B) is only allowed in the old regime.
In the old tax regime, senior citizens (60-80 years) have an exemption limit of Rs 3L, and super senior citizens (80+) have Rs 5L. In the new regime, the slabs are the same for all ages.
