How this is calculated +

1. Gross total income. Sum of all income heads — salary, house property (net of standard 30% & 24(b) interest), business / profession, slab-rate capital gains and other sources.

GTI = Salary + House Property + Business + Capital Gains + Other Sources

2. Standard deduction. Salaried individuals get ₹50,000 under the old regime and ₹75,000 under the new regime (FY 2025-26).

3. Chapter VI-A deductions. Available only under the old regime. 80C is capped at ₹1,50,000; 80CCD(1B) adds an additional ₹50,000 for NPS Tier I; 80D varies by age band (₹25,000 / ₹50,000 / ₹1,00,000). Home loan interest is allowed up to ₹2,00,000 under Section 24(b) for self-occupied property.

Taxable Income = GTI − Std. Deduction − Σ(Chapter VI-A) − HRA Exempt

4. Slab-wise tax (FY 2025-26).

Old regime · Below 60: 0–2.5L: nil · 2.5–5L: 5% · 5–10L: 20% · 10L+: 30% New regime: 0–4L: nil · 4–8L: 5% · 8–12L: 10% 12–16L: 15% · 16–20L: 20% · 20–24L: 25% · 24L+: 30%

5. Rebate under Section 87A. Old regime: full rebate up to ₹12,500 if taxable income ≤ ₹5,00,000. New regime: full rebate up to ₹60,000 if taxable income ≤ ₹12,00,000, with marginal-relief smoothing just above the threshold.

6. Surcharge. Levied on the income-tax amount, not on income. Old regime tops out at 37%; new regime caps at 25%.

50L–1Cr: 10% · 1Cr–2Cr: 15% · 2Cr–5Cr: 25% · >5Cr (old): 37% / (new): 25%

7. Health & Education cess. Flat 4% on the (tax + surcharge) line.

Total Tax = (Slab Tax − Rebate + Surcharge) × 1.04
