How to calculate income tax for 2026-27: four worked examples under both regimes
Step-by-step income tax calculations for 2026-27: a ₹12.75 lakh salary, ₹18 lakh with deductions, a senior pensioner and an investor.
Estimate income tax under the default new regime (section 202) for tax year 2026-27, with the 4% cess built into the slab rates.
How to use it. Enter your gross income for tax year 2026-27 (1 April 2026 to 31 March 2027) that is taxed at slab rates: salary, pension, interest, rent after its 30% deduction, and similar income. Leave out capital gains on listed equity, which are taxed at their own rates; use the capital gains calculator for those. In the second box, enter the deductions the new regime allows. For most employees that is the ₹75,000 standard deduction, plus any employer NPS contribution shown on the salary slip.
Rates used. These are the section 202(1) slabs of the Income-tax Act, 2025, with the 4% cess built in: nil up to ₹4 lakh, then 5.2%, 10.4%, 15.6%, 20.8% and 26% in ₹4 lakh steps, and 31.2% above ₹24 lakh.
The rebate. The calculator cannot apply conditions, so handle the section 156 rebate yourself. If total income (the first output) is ₹12 lakh or less, a resident owes no slab tax: enter the tax shown as the rebate, or simply read the result as nil. If total income is just above ₹12 lakh, up to roughly ₹12.7 lakh, marginal relief caps the tax at the excess over ₹12 lakh plus cess. For example, at ₹12,25,000 the tax is ₹25,000 × 1.04 = ₹26,000.
Worked example (illustrative). Gross salary ₹18,00,000 less ₹75,000 gives total income of ₹17,25,000. Slab tax is ₹20,000 + ₹40,000 + ₹60,000 + ₹25,000 = ₹1,45,000, and with cess ₹1,50,800. The default inputs give this result.
Limits. Surcharge (above ₹50 lakh) and the special rates on capital gains are not included. Non-residents do not get the rebate. See the new regime slab guide.
