Quick Tax Calculator

Take your gross total income, subtract eligible deductions for your chosen regime, and apply slabs. Under new regime FY 2025-26: nil up to Rs 4 lakh, 5% on Rs 4-8 lakh, 10% on Rs 8-12 lakh, 15% on Rs 12-16 lakh, 20% on Rs 16-20 lakh, 25% on Rs 20-24 lakh, 30% above Rs 24 lakh. Apply 87A rebate up to Rs 60,000 if income is Rs 12 lakh or less. Add surcharge if income exceeds Rs 50 lakh and 4% cess on the total. For salaried, deduct Rs 75,000 standard deduction first. A Rs 14 lakh salaried employee under new regime owes around Rs 60,000 plus cess. Old regime gives different numbers; comparison tools help.

The slabs under Section 115BAC for FY 2025-26 (AY 2026-27) are: 0% up to Rs 4,00,000; 5% on Rs 4,00,001 to Rs 8,00,000; 10% on Rs 8,00,001 to Rs 12,00,000; 15% on Rs 12,00,001 to Rs 16,00,000; 20% on Rs 16,00,001 to Rs 20,00,000; 25% on Rs 20,00,001 to Rs 24,00,000; and 30% above Rs 24,00,000. These are the revised slabs introduced in Budget 2025 (effective from FY 2025-26 onwards), wider than the earlier new-regime slabs. With Rs 75,000 standard deduction and Rs 60,000 87A rebate up to Rs 12 lakh income, salaried employees pay zero tax up to Rs 12.75 lakh of gross salary.

Standard deduction under Section 16(ia) is subtracted from gross salary before computing tax at slabs. Under the new regime for FY 2025-26, the standard deduction is Rs 75,000 for salaried employees and pensioners. Under the old regime it remains Rs 50,000. So if your gross salary is Rs 14 lakh, taxable salary under the new regime is Rs 14,00,000 − Rs 75,000 = Rs 13,25,000, on which slab tax is then computed. No separate documents are needed; the deduction is automatic in your Form 16. It applies to family pension recipients too (with a slightly different limit of Rs 25,000 under new regime).

Yes, under the old regime only. For senior citizens aged 60-79, the basic exemption limit is Rs 3 lakh instead of Rs 2.5 lakh; for super seniors aged 80 and above, it's Rs 5 lakh. Other slabs follow the same structure (5%, 20%, 30%) but kick in at higher thresholds. Under the new regime, the basic exemption is uniformly Rs 4 lakh for everyone, regardless of age, so seniors don't get an extra age-based break. The 87A rebate threshold (Rs 5 lakh old, Rs 12 lakh new) and amounts (Rs 12,500 old, Rs 60,000 new) are also age-neutral. Many seniors with pension income still find the old regime favourable due to higher deductions claimable.

Tax computation mechanics are identical for residents and non-residents on Indian-source income under both regimes. Same slabs, same surcharge, same cess. The differences are: (a) NRIs cannot claim the Section 87A rebate, so their income above Rs 4 lakh is taxed without the rebate cushion; (b) basic exemption limit cannot be set off against special-rate capital gains for NRIs; (c) some deductions like Section 80TTB (savings interest for seniors) are not available; (d) DTAA may give relief on specific income types. Residents are taxed on global income; non-residents only on Indian income. Filing Form 67 for foreign tax credit applies only to residents.

On the income tax e-filing portal and most reputable calculators, yes, the 87A rebate is computed automatically once you enter your total income, residential status and regime. The system checks eligibility (resident individual, total income within threshold) and applies the rebate before adding cess. However, in older or simpler offline calculators, you may need to apply it manually: subtract the rebate amount (lower of tax payable or Rs 60,000 new / Rs 12,500 old) from the tax computed at slab rates. Always verify on Form 26AS and pre-filled ITR data; mismatches between portal and personal calculation are usually due to special-rate capital gains being incorrectly included in rebate-eligible income.

Health and Education Cess at 4% is added to the aggregate of income tax and surcharge, after applying 87A rebate. The sequence is: compute slab tax → reduce by 87A rebate (if eligible) → add applicable surcharge if income crosses thresholds → add 4% cess on the post-surcharge amount → that's your total tax payable. Take Rs 15 lakh income under new regime: slab tax around Rs 1,05,000, no 87A rebate (income above Rs 12 lakh), no surcharge (below Rs 50 lakh), cess at 4% = Rs 4,200, total Rs 1,09,200. Same logic across both regimes. The cess is non-creditable and cannot be claimed as a deduction anywhere.
