FY 2025-26 or Tax Year 2026-27? Income earned from April 2025 to March 2026 is FY 2025-26 (assessment year 2026-27), filed in 2026 under the Income-tax Act, 1961. Income from April 2026 onwards is Tax Year 2026-27 under the Income-tax Act, 2025. The rates are the same; section numbers and some forms change. See tax year explained.
What the calculator leaves out. Capital gains taxed at special rates, agricultural income, non-residents, alternate minimum tax and employer NPS contributions. If any of these apply, or you have business income, a CA-filed return is the safer route.

Questions
Is income up to ₹12 lakh tax-free under the new regime?
Yes, for a resident individual whose income is all taxed at slab rates. The rebate (section 87A of the 1961 Act, section 156 of the 2025 Act) is up to ₹60,000, which cancels the tax on taxable income up to ₹12 lakh. A salaried person effectively pays nothing up to ₹12.75 lakh after the ₹75,000 standard deduction. The rebate does not cover capital gains taxed at special rates.
What happens just above ₹12 lakh?
Marginal relief applies: the tax payable cannot be more than the income above ₹12 lakh. For taxable income of ₹12,25,000 the slab tax is ₹63,750, but you pay ₹25,000 plus 4% cess.
Did the slabs change for Tax Year 2026-27?
No. The Income-tax Act, 2025 applies from 1 April 2026, but section 202 keeps the same new-regime slabs as FY 2025-26, and Budget 2026 made no change to personal rates. The standard deduction stays ₹75,000 under the new regime and ₹50,000 under the old.
Which regime should I choose?
The new regime is the default and usually wins unless your old-regime deductions are large: HRA, 80C investments, health insurance and home-loan interest together. Enter them above and the calculator shows both. If you have business income, you can switch back to the new regime only once, so take advice first.
What are the old-regime slabs?
Below 60: nil up to ₹2.5 lakh, 5% to ₹5 lakh, 20% to ₹10 lakh, 30% above. Aged 60 to 79: nil up to ₹3 lakh. Aged 80 or more: nil up to ₹5 lakh, then 20% and 30%. A rebate of up to ₹12,500 makes tax nil if taxable income is up to ₹5 lakh.
How is surcharge worked out?
Surcharge is 10% above ₹50 lakh, 15% above ₹1 crore and 25% above ₹2 crore; under the old regime it is 37% above ₹5 crore. Marginal relief stops the surcharge from costing more than the income above each threshold. Cess of 4% is then charged on tax plus surcharge.
