Income Tax Calculator (India)
Compare new regime slabs (FY 2026-27 illustrative) with a simplified old regime model including common deductions. Figures are not legal or filing advice — verify with the latest Finance Act and your CA.
Disclaimer: Tax law changes frequently. This tool uses rounded slab math, a 4% health & education cess on tax, standard deduction defaults, and a simplified rebate (new regime: no tax if taxable income ≤ ₹7 lakh after standard deduction, matching common 87A-style relief — confirm eligibility). Always validate against official notifications.

How income tax estimation works
India’s income tax combines progressive slabs (higher slices of income face higher marginal rates) with rebates, cess, and surcharge (not modeled here for very high incomes). The new tax regime typically offers lower rates but fewer deductions; the old regime keeps Section 80C, 80D, HRA, and other provisions if you qualify and opt in where allowed.
For this calculator, new regime taxable income starts from gross salary-like income minus a configurable standard deduction (commonly ₹50,000 for salaried taxpayers — verify the applicable year’s limit). We then apply the slab structure you specified: nil up to ₹3 lakh, then 5% from ₹3–7 lakh, 10% from ₹7–10 lakh, 15% from ₹10–12 lakh, 20% from ₹12–15 lakh, and 30% above ₹15 lakh. If taxable income after standard deduction is ₹7 lakh or below, we set tax to zero to reflect typical Section 87A-style relief for residents — this is a simplification; actual eligibility depends on income type and current law.
The old regime path subtracts standard deduction (₹50,000), capped 80C (₹1.5 lakh), your 80D entry, HRA, and other deductions from gross income, then applies classic slabs with a basic exemption that depends on age: ₹2.5 lakh below 60, ₹3 lakh for 60–80, and ₹5 lakh above 80. Marginal rates are 5% above the basic exemption up to ₹5 lakh, 20% from ₹5–10 lakh, and 30% above ₹10 lakh. We add 4% cess on the tax for both regimes in this demo.
What to verify manually: surcharge on income above ₹50 lakh, alternate minimum tax, perquisites, capital gains, house property loss set-off, and the exact standard deduction for your assessment year. Use this page to build intuition and compare regimes side by side, then confirm with Form 16, AIS, or a qualified professional before filing.
FAQ
Which regime should I choose?
Compare total tax under both regimes each year — the better choice depends on your deductions, rent, loans, and income mix. This calculator gives a directional comparison only.
Why doesn’t my tax match Form 16?
Employers apply TDS with payroll-specific proofs, perquisites, and timing. We don’t model all salary components or filing rebates beyond the simplified 87A-style rule.
Are cess and surcharge included?
We add 4% cess on computed tax. Surcharge for high income is not included — add that manually if applicable.
Is HRA calculated automatically?
No. Enter the HRA exemption you are eligible for (as per rent receipts and metro rules) or leave at zero to learn the impact of HRA on the old regime.
Can NRIs use this?
Residential status changes exemptions and slab applicability. This tool assumes resident individual rules unless you adjust inputs yourself.
