Old vs new tax regime comparator
For FY 2025-26 (assessment year 2026-27), including the revised slabs and the section 87A rebate.
Includes 4% health and education cess and surcharge where applicable. Indicative only — it does not model capital gains, clubbing, relief under section 89 or the many situation-specific rules. Have a CA model your actual position.
How the comparison works
The new regime for FY 2025-26 taxes income in seven slabs: nil up to ₹4 lakh, then 5, 10, 15, 20 and 25 percent in ₹4 lakh steps to ₹24 lakh, and 30 percent above. Salaried taxpayers and pensioners deduct a standard ₹75,000 first, and the section 87A rebate wipes out the tax where taxable income is up to ₹12 lakh, with marginal relief just above it. Almost no other deduction is allowed.
The old regime keeps the familiar slabs of 5 percent above ₹2.5 lakh, 20 percent above ₹5 lakh and 30 percent above ₹10 lakh, a standard deduction of ₹50,000, the rebate up to ₹5 lakh of taxable income, and every deduction: section 80C, 80D, home loan interest, HRA, and the rest. It wins only when those deductions are large.
Both regimes add surcharge above ₹50 lakh and the 4 percent health and education cess, which the calculator includes. It does not model capital gains, income from more than one house property, relief under section 89, or the clubbing and agricultural-income rules; where those apply, the answer needs a computation, not a calculator.
When the old regime still wins
As a rule of thumb, the old regime pulls ahead when deductions and exemptions together exceed roughly ₹3.75 lakh at incomes around ₹12 to ₹15 lakh, and more than that as income rises: a maxed section 80C, a home loan interest deduction of ₹2 lakh, meaningful HRA and a family health policy will get there. Salaried taxpayers can choose afresh each year at filing; taxpayers with business income who opt out of the new regime through Form 10-IEA get one switch back, so their choice needs more care. Income from 1 April 2026 falls under the Income-tax Act, 2025, where the same two regimes continue under new section numbers.
