Why can ₹12.75 lakh salary result in zero tax?
₹12,75,000 salary − ₹75,000 standard deduction = ₹12,00,000 taxable income. Under the New Regime, the slab tax is ₹60,000 and Section 156 (formerly 87A) can rebate that amount for an eligible resident individual. This assumes only normal-rate income and no special-rate income.

Income tax guide for Tax Year 2026–27
Comparing Old vs New Tax Regime estimates
Compare both regimes using the same income, age and residential status. In Detailed mode, add your eligible salary exemptions and deductions; the calculator applies the supported amounts separately for each regime. Review annual tax, the estimated difference and each detailed breakdown rather than comparing slab rates alone.
Gross salary vs taxable income
Gross salary includes the full employer NPS contribution before exemptions and standard deduction. If your salary figure excludes it, choose that option in Detailed mode; the contribution is added once before the eligible deduction. Taxable income is the amount remaining after the calculator combines normal-rate income, makes supported salary and house-property adjustments, and subtracts applicable deductions. Each regime's breakdown shows this amount separately; it is not the same as take-home pay.
How income tax is calculated
Income after exemptions and house-property adjustments is reduced by standard deduction and eligible deductions. Total income is rounded under Section 516 before testing slabs, rebate and surcharge thresholds. Final tax including cess is rounded to ₹10 after discarding paise; intermediate amounts are not rounded.
Standard deduction
Eligible salary receives up to ₹75,000 under the new regime or ₹50,000 under the old regime. The deduction cannot exceed salary after exemptions.
Section 156 (formerly 87A) rebate
Eligible residents can receive up to ₹60,000 in the new regime at taxable income up to ₹12 lakh, or ₹12,500 in the old regime up to ₹5 lakh.
Marginal relief
Marginal relief limits sudden additional tax immediately after the new-regime rebate threshold and applicable surcharge thresholds.
HRA exemption
Old-regime HRA exemption is the least of actual HRA, rent above 10% of eligible salary, or 50% of salary for an eligible metro and 40% otherwise.
Eligible deductions in Detailed mode
Detailed mode supports inputs for 80C, 80D, 80E, 80G, 80TTA, 80TTB and NPS (legacy names; current Sections 123, 126, 129, 133, 153 and 124), alongside salary exemptions and house-property income. Supported limits and regime restrictions are applied, but a cap does not establish your eligibility. Verify the deductible amount before entering it, particularly for donations, health insurance and employer NPS contributions.
Why ₹12.75 lakh salary can result in zero tax
₹12,75,000 salary minus ₹75,000 standard deduction equals ₹12,00,000 taxable income. For an eligible resident with no special-rate income, slab tax may be offset by Section 156 (formerly 87A) rebate.
Important limitations of this calculator
This estimator covers normal-rate individual income. It excludes special-rate calculations and cannot verify documents, donation categories, carried-forward losses or every filing circumstance.
