When ticked, the standard deduction applies (Rs 75,000 new regime / Rs 50,000 old regime).
These reduce your taxable income only if you choose the old regime. Limits are applied automatically: 80C up to Rs 1.5 lakh, home loan interest up to Rs 2 lakh, 80D up to Rs 1 lakh.

What are the new regime slabs for FY 2026-27?
The new (default) regime slabs are: Rs 0-4 lakh at 0%, Rs 4-8 lakh at 5%, Rs 8-12 lakh at 10%, Rs 12-16 lakh at 15%, Rs 16-20 lakh at 20%, Rs 20-24 lakh at 25% and above Rs 24 lakh at 30%. These slabs are the same for every age group.
Which regime should I choose?
For most salaried individuals the new regime wins after the Budget 2025 changes, thanks to its generous slabs, Rs 75,000 standard deduction and Rs 60,000 rebate (zero tax up to Rs 12.75 lakh salary). The old regime only wins if you claim large deductions like 80C, HRA, home loan interest and 80D. Compare both above for your exact income.
How is the 87A rebate applied?
The rebate is deducted from your slab tax before surcharge and cess are added. Under the new regime it is up to Rs 60,000 for total income up to Rs 12 lakh; under the old regime it is up to Rs 12,500 for income up to Rs 5 lakh.
What is the standard deduction?
A flat deduction salaried individuals and pensioners can claim without any investment proof: Rs 75,000 under the new regime and Rs 50,000 under the old regime for FY 2026-27.
How are surcharge and cess calculated?
A surcharge of 10% applies between Rs 50 lakh and Rs 1 crore, 15% between Rs 1 crore and Rs 2 crore, 25% between Rs 2 crore and Rs 5 crore, and 37% above Rs 5 crore (old regime only; the new regime is capped at 25%). Marginal relief smooths the jump just past each threshold. A 4% health and education cess applies on income tax plus surcharge.
Are these slabs confirmed for FY 2026-27?
Yes. The February 2026 Union Budget made no change to slabs, standard deduction, the 87A rebate, surcharge or cess, so FY 2026-27 (AY 2027-28) values are identical to FY 2025-26. The new Income-tax Act 2025 (effective 1 April 2026) only renumbers provisions without changing rates.
This calculator provides an estimate based on FY 2026-27 slab rates and standard assumptions (standard deduction, 87A rebate, surcharge and cess). It does not account for every provision of the Income-tax Act (for example special-rate capital gains, AMT, or the finer points of HRA). This is not tax advice - confirm with a qualified chartered accountant before filing your return.
