Note: This calculator estimates tax for a resident individual (below 60 years) under Section 202 of the Income Tax Act, 2025 (New Regime — corresponds to the erstwhile Section 115BAC) and the Old Regime, for Tax Year 2026-27, including the rebate under Section 156 (formerly Section 87A) and marginal relief. It does not account for surcharge on very high incomes, senior citizen slabs, or special-rate income like capital gains. For your exact liability, consult a chartered accountant or use the official Income Tax e-filing utility.

How & Why to Use the Income Tax Calculator

Since Budget 2025, the New Regime is the default — but the Old Regime can still work out cheaper if you claim enough deductions. Here's how to use this tool properly, and why comparing both regimes matters.

How to Use This Calculator

Step 1
Enter your annual gross income
Type your total annual income before any deductions — this is usually the CTC-equivalent or gross salary shown on your Form 16 or payslip.
Step 2
Pick New Regime or Old Regime
The New Regime is selected by default since it's now the default option under the Income Tax Act. Switch to Old Regime to see how deductions change your tax.
Step 3
Add your deductions (Old Regime)
If comparing the Old Regime, fill in your actual 80C investments, health insurance premium, home loan interest and other eligible deductions.
Step 4
Check the regime comparison card
The "Old vs New Regime" card at the bottom of the results shows which regime saves you more tax for your exact numbers — no manual comparison needed.

Why You Need an Income Tax Calculator

Choosing a Regime
The right choice depends entirely on your deductions
Someone with high 80C, 80D and home loan interest claims can still save more under the Old Regime, even though the New Regime is now the default for most taxpayers.
Salary Negotiation
In-hand pay is what actually matters
A higher CTC doesn't always mean higher take-home pay once tax is applied — knowing your post-tax number helps you evaluate offers and increments accurately.
Section 87A Rebate
Zero tax up to ₹12 lakh isn't automatic
The ₹60,000 rebate under the New Regime only applies below a specific threshold, and marginal relief rules just above it are easy to miscalculate by hand.
Tax Planning
Plan investments before the financial year ends
Seeing your projected tax early in the year gives you time to plan 80C investments, health insurance, or NPS contributions before the March 31 deadline.
Freelancers & Consultants
Estimate advance tax instalments
Self-employed professionals can use the annual tax figure to work out quarterly advance tax payments and avoid interest under Sections 234B/234C.
Avoiding Surprises
No surprises at ITR filing time
A quick estimate through the year means your actual tax liability at filing time is rarely a shock — helping you avoid last-minute cash-flow stress.

Tax Regime Fundamentals

Old vs New Tax Regime — Explained

Since FY 2023-24, India has run two parallel tax systems. Here's how the two compare, and which one tends to suit different kinds of taxpayers.

🆕
New Regime (Default)
Lower slab rates with a ₹75,000 standard deduction, but almost no other deductions or exemptions — no 80C, 80D, or HRA. Automatically applied unless you opt for the Old Regime.
Tax-free up to ₹12.75 lakh salary
Best suited to taxpayers with few investments, no home loan, and no HRA to claim — most young salaried individuals fall into this category.
📜
Old Regime (Opt-in)
Higher slab rates, but allows deductions like 80C (₹1.5L), 80D, HRA, home loan interest and more. You must actively choose it while filing your return.
Tax-free up to ₹5 lakh taxable income
Works better if your total eligible deductions are large enough to bring your taxable income meaningfully below the New Regime's effective threshold.
⚖️
Which One Should You Choose?
As a rule of thumb, if your total deductions (80C + 80D + home loan interest + HRA) exceed roughly ₹4-4.5 lakh, the Old Regime often works out cheaper. Below that, the New Regime usually wins.
Compare both — don't assume
The exact break-even point shifts with your income level, so always run the actual numbers rather than relying on a rule of thumb.
➕
Cess & Section 87A Rebate
A 4% Health & Education Cess is added on top of the computed tax under both regimes. Section 87A gives a full rebate — zero tax — below a set taxable-income threshold in each regime.
New: ₹12L threshold · Old: ₹5L threshold
Marginal relief also applies just above these thresholds, so tax doesn't jump sharply the moment you cross ₹12 lakh (New) or ₹5 lakh (Old).

ℹ️ About This Tool

What Is the Income Tax Calculator?

The Income Tax Calculator is a free online tool that instantly computes your income tax liability for Tax Year 2026-27 — governed by the new Income Tax Act, 2025 — under both the New Tax Regime and the Old Tax Regime, so you can see which one saves you more.

This calculator is free to use, requires no signup, and works for salaried employees, freelancers and consultants alike. Simply enter your annual income, choose a regime, add your deductions if relevant, and see your slab-wise tax, Section 87A rebate, cess and in-hand income calculated live.

Budget 2025 made the New Tax Regime the default option for all taxpayers from FY 2025-26 onwards, and Budget 2026 left the slabs, rebate and standard deduction unchanged for Tax Year 2026-27, with a significantly higher rebate that makes taxable income up to ₹12 lakh completely tax-free — or up to ₹12.75 lakh for salaried individuals once the ₹75,000 standard deduction is applied. This shift means most salaried taxpayers with modest investments now pay little to no tax, without needing to actively plan deductions. From 1 April 2026, this framework is governed by the new Income Tax Act, 2025, which replaces the Income Tax Act, 1961 and its Financial Year / Assessment Year system with a single unified "Tax Year". The New Regime now sits under Section 202 (previously Section 115BAC) and the rebate under Section 156 (previously Section 87A) — the underlying rates and thresholds are unchanged, only the section numbers and terminology have changed.

The Old Regime hasn't disappeared, though — you can still opt into it every year while filing your return. It carries higher slab rates but allows a wide range of deductions: up to ₹1.5 lakh under Section 80C for investments like PF, ELSS and PPF, up to ₹2 lakh in home loan interest under Section 24(b), health insurance premiums under Section 80D, and House Rent Allowance exemption if you pay rent. For someone with a home loan, a large family health cover, and full 80C investments, the Old Regime can still work out cheaper than the New Regime, even with its lower ₹5 lakh rebate threshold.

Because the two regimes tax the same income so differently, comparing them side by side — rather than guessing — is the only reliable way to know which one is right for you. This tool runs both calculations simultaneously on the same income and deduction inputs, and flags which regime results in a lower total tax outgo, including the effect of Section 87A rebate and marginal relief near the ₹12 lakh (New) and ₹5 lakh (Old) thresholds.

This calculator is built for quick, practical estimation — it covers standard slab-rate tax, the 4% Health & Education Cess, and Section 87A rebate with marginal relief. It does not compute surcharge for very high incomes, senior/super-senior citizen slabs, or tax on special-rate income like capital gains, lottery winnings, or virtual digital assets. For a return-ready figure, always cross-check with a chartered accountant or the official Income Tax Department e-filing portal.
