What Is the Income Tax Calculator?

Last updated: July 2026 · Reviewed by the NeftCal editorial team

An income tax calculator estimates how much tax you owe and what you take home, based on your income, deductions, and the tax rules of your country. NeftCal's income tax calculator covers FY 2025-26 for seven countries — India (old regime vs new regime), the United States, the United Kingdom, Australia, Germany, the UAE, and Singapore. It works as a take-home pay calculator, a net salary calculator, and an effective tax rate calculator in one, built for salaried employees, freelancers, and expats who want a quick, country-specific estimate without opening a spreadsheet or reading tax legislation line by line.

Enter your gross annual income and, for India, other income plus itemized deductions such as the Section 80C deduction, HRA exemption, and NPS 80CCD(1B) deduction, along with home loan interest under Section 24(b) — and this India income tax calculator FY 2025-26 weighs the old regime vs new regime 2025 side by side, including the Budget 2025 new tax regime slabs and the revised Section 87A rebate threshold. Switch the country dropdown and the same tool turns into a US federal income tax calculator with FICA logic for Social Security and Medicare and a 401(k) pre-tax contribution field; a UK income tax calculator with a personal allowance taper and National Insurance; an Australia income tax calculator with the Low Income Tax Offset (LITO) and Medicare levy; a Germany income tax calculator with Steuerklasse and Kirchensteuer; a UAE income tax overview; and a Singapore income tax calculator with CPF contributions and earned income relief. This page's in-depth guide, formula walkthrough, and worked example focus specifically on India's old vs new regime comparison, since that is this calculator's most detailed mode — see the calculator above for the other six countries.

Who Should Use This Calculator

Salaried employees deciding which Indian tax regime to declare to their employer, freelancers and consultants estimating provisional tax, job seekers comparing offers, HR and payroll teams sanity-checking take-home figures, and anyone relocating between the seven supported countries who wants a quick side-by-side estimate of tax and net pay.

Why It Matters for Financial Planning

Knowing your real take-home pay — not just your headline salary — matters when comparing job offers, negotiating a raise, planning a relocation, or deciding how much to invest in tax-advantaged instruments like Section 80C investments, NPS, or a pension. A dependable net salary calculator also helps with budgeting, rent applications, and loan eligibility, since lenders and landlords often ask for post-tax income. Because slabs and rebates change almost every year — as they did with Budget 2025's new tax regime restructuring in India — a calculator kept current for the latest tax year saves you from relying on outdated rules of thumb.

Common Scenarios

  • Comparing India's old regime vs new regime before declaring your choice to your employer at the start of FY 2025-26
  • Estimating TDS deducted by an employer against the final tax computed under each regime
  • Checking take-home pay alongside a paycheck / salary calculator for monthly budgeting
  • Cross-checking indirect tax costs with the GST calculator when running a small business or freelance practice
  • Planning Section 80C investments through a PPF calculator or ELSS-focused SIP calculator before the old-regime deduction deadline
  • Comparing a US job offer's take-home pay using the dedicated federal income tax calculator

Tips for Accurate Results

  • Use your gross annual salary before any deductions, not your monthly in-hand pay, for the most accurate estimate
  • For India, compare both regimes with your actual deduction amounts (Section 80C, HRA exemption, NPS 80CCD, home loan interest 24b) rather than the defaults — the "better" regime depends entirely on how much you can genuinely claim
  • Select the correct age group (general, senior 60–79, or super senior 80+) since the old regime's basic exemption limit changes with age
  • If you're calculating US federal income tax, remember FICA and any state income tax are worked out separately from the federal brackets — enter your actual state rate and 401(k) contribution for a true take-home figure
  • Treat every result as a close estimate, not a filing-ready figure — surcharge, capital gains, bonuses, and multiple income sources can shift your final liability, so confirm with a tax professional or the official Income Tax Department portal for complex situations
Formula

How Income Tax Is Calculated — India Old vs New Regime, FY 2025-26

The exact slab structure and rebate logic this calculator applies for a general (below-60) taxpayer

New Regime (Default) — FY 2025-26
Taxable Income = Gross Salary + Other Income − ₹75,000 (standard deduction)
Tax before cess = sum of (slab amount × slab rate) across the 6 bands below
If Taxable Income ≤ ₹12,00,000 → Section 87A rebate reduces tax before cess to ₹0

Old Regime — FY 2025-26
Taxable Income = Gross Salary + Other Income − ₹50,000 (standard deduction) − Section 80C (≤ ₹1,50,000) − HRA exemption − NPS 80CCD(1B) (≤ ₹50,000) − 80D health insurance − Home loan interest 24(b) (≤ ₹2,00,000)
Tax before cess = sum of (slab amount × slab rate) across the age-based slabs below
If Taxable Income ≤ ₹5,00,000 → Section 87A rebate reduces tax before cess to ₹0

Final Tax Payable (both regimes)
Final Tax = (Tax before cess − 87A rebate if eligible) × 1.04  (4% Health & Education Cess)
New Regime Slab (as used by this calculator)Rate

₹5,00,001 – ₹10,00,00020%
Above ₹10,00,00030%

⚙️ Why This Formula Works

Both regimes use progressive (marginal) slab taxation — each portion of income is taxed only at the rate for that band, not the whole income at the top rate. The Section 87A rebate then works as a cliff: if your final taxable income falls at or below the threshold (₹5 lakh old regime, ₹12 lakh new regime), the computed tax is reduced to zero before cess. The 4% Health & Education Cess is applied last, on whatever tax remains after the rebate, in both regimes.

🎯 When to Use Each Regime

  • Old regime — when your eligible deductions (80C, HRA, NPS, 80D, home loan interest) are substantial relative to your income
  • New regime — when your deductions are modest, since lower slab rates and the ₹12 lakh rebate threshold often produce less tax
  • Both — whenever you're unsure; salaried employees can compare and choose freely each year

📋 Assumptions

  • You are a resident individual taxpayer with salary and/or other income, for FY 2025-26 (AY 2026-27)
  • Deduction amounts you enter (80C, NPS, 80D, home loan interest) are within the legal caps and genuinely eligible
  • No surcharge is modeled — this calculator assumes income levels below the surcharge thresholds
  • No capital gains, business income, or presumptive taxation is included

⚠️ Limitations of the Formula

  • Does not calculate surcharge on income above ₹50 lakh, or marginal relief on surcharge
  • Does not model capital gains, business/professional income, or presumptive taxation schemes
  • Does not compute the HRA exemption formula itself — you must enter the exempt amount
  • Not a substitute for filing through the official Income Tax Department portal or a chartered accountant's computation

Example

Worked Example — India Old vs New Regime

A step-by-step FY 2025-26 calculation using this calculator's own default input values

Scenario

A salaried employee below age 60 earns a gross annual salary of ₹12,00,000 with no other income. They claim the full Section 80C limit, the full NPS 80CCD(1B) limit, and a ₹25,000 health insurance premium under 80D, with no HRA exemption or home loan interest claimed in this example.

Gross Salary₹12,00,000
Other Income₹0
Section 80C₹1,50,000
HRA Exemption₹0
NPS 80CCD(1B)₹50,000
80D Health Insurance₹25,000
Home Loan Interest 24(b)₹0
Age GroupGeneral (below 60)
Step 1 — Old regime taxable income: ₹12,00,000 − ₹50,000 (std. deduction) − ₹1,50,000 (80C) − ₹50,000 (NPS) − ₹25,000 (80D) = ₹9,25,000.
Step 2 — Old regime tax before cess: 5% on ₹2,50,000–₹5,00,000 slab = ₹12,500; 20% on ₹5,00,000–₹9,25,000 (₹4,25,000) = ₹85,000. Total = ₹97,500. Taxable income is above the ₹5,00,000 rebate threshold, so no 87A rebate applies. With 4% cess: ₹97,500 × 1.04 = ₹1,01,400.
Step 3 — New regime taxable income: ₹12,00,000 − ₹75,000 (std. deduction) = ₹11,25,000.
Step 4 — New regime tax before cess: 5% on ₹4,00,000–₹8,00,000 slab = ₹20,000; 10% on ₹8,00,000–₹11,25,000 (₹3,25,000) = ₹32,500. Total = ₹52,500. Since taxable income (₹11,25,000) is at or below the ₹12,00,000 rebate threshold, Section 87A reduces this to ₹0 before cess, so final new-regime tax is also ₹0.
Old Regime Tax
₹1,01,400
New Regime Tax
₹0
Savings with New Regime
₹1,01,400

Explanation: In this example the new regime wins decisively, purely because the taxable income (₹11,25,000) lands under the ₹12 lakh Section 87A rebate threshold introduced by Budget 2025 — that single cliff effect zeroes out the tax, even before comparing slab rates. If the same taxpayer earned more (pushing new-regime taxable income above ₹12 lakh) or claimed larger old-regime deductions such as a home loan interest claim, the comparison could shift. This is exactly why comparing both regimes with your own numbers — not relying on a generic rule of thumb — matters.

Interpretation

Understanding Your Results

What your effective tax rate roughly tells you

Your effective tax rate — final tax payable divided by gross income — is a more useful comparison point than the headline slab rate, since it accounts for exemptions, deductions, and the 87A rebate all at once. The bands below are general reference points for salaried individuals in India, not an official Income Tax Department benchmark.

Effective Tax RateGeneral ReadTypical Context
0%No tax payableTaxable income within the applicable 87A rebate threshold
Under 10%Relatively low tax burdenIncome modestly above the rebate threshold, or strong deduction use under the old regime
10% – 20%Moderate tax burdenTypical for salaried income roughly in the ₹15–35 lakh range
Above 20%Higher tax burdenHigher income levels where more of the income falls in the 20–30% slabs

Old vs new regime break-even: as a rough rule of thumb, if your genuinely eligible old-regime deductions exceed roughly ₹4.5–5.25 lakh, the old regime can work out cheaper for you — but the exact break-even point shifts with your income level, so treat this as a starting intuition and confirm with your own numbers in the calculator above, not as a fixed rule.

For higher earners: this calculator does not model surcharge, which applies above ₹50 lakh in real Indian tax law. If your income is in that range, treat the result as a starting estimate only and verify your surcharge liability separately.

Common Mistakes and Expert Tips

❌ Common Mistakes

  • Assuming the new regime is always better without running the numbers — Budget 2025 changed the calculus significantly
  • Forgetting the 4% Health & Education Cess when comparing headline slab rates
  • Mixing up the standard deduction amounts — ₹50,000 old regime vs ₹75,000 new regime
  • Entering monthly salary instead of annual gross salary
  • Claiming the full Section 80C limit without actually having eligible investments or expenses
  • Assuming business-income taxpayers can switch regimes every year like salaried employees can

💡 Expert Tips & Best Practices

  • Recompute at year-end once your actual 80C, 80D, and NPS investments and HRA are finalized, not just estimated in April
  • If your total eligible deductions are modest, the new regime's lower slabs plus the ₹12L rebate threshold often wins
  • Double-check the age-based exemption limit is applied correctly if you're a senior or super senior citizen
  • Compare take-home pay, not just tax payable, when evaluating job offers
  • Keep proof of deductions (80C receipts, rent receipts for HRA, home loan interest certificate) even under the old regime, in case of scrutiny
FAQ

Frequently Asked Questions

Common questions about India's income tax regimes and this calculator

What is an income tax calculator and how does it work?
An income tax calculator estimates how much income tax you owe based on your income, deductions, and the tax rules for your country and tax year. NeftCal's income tax calculator supports India (FY 2025-26, old and new regime), the United States, United Kingdom, Australia, Germany, UAE, and Singapore. You enter your gross income and applicable deductions, and it applies the relevant slab rates, rebates, and levies instantly in your browser to estimate your tax payable and take-home pay.
What's the difference between the old tax regime and the new tax regime in India?
The old regime uses four income slabs (nil up to ₹2.5 lakh, 5% up to ₹5 lakh, 20% up to ₹10 lakh, 30% above) but lets you claim deductions such as Section 80C, HRA exemption, NPS 80CCD(1B), health insurance under 80D, and home loan interest under Section 24(b). The new regime, as restructured by Budget 2025, uses six slabs starting at ₹4 lakh with lower rates but does not allow most of those deductions. Which one results in lower tax depends on how much you can genuinely claim under the old regime — this calculator compares both side by side.
What changed under Budget 2025 for the new tax regime?
Budget 2025 restructured the new regime into six income bands starting from ₹4 lakh (previously ₹3 lakh) and raised the Section 87A rebate threshold from ₹7 lakh to ₹12 lakh of taxable income. Combined with the ₹75,000 standard deduction, this means salaried taxpayers with taxable income up to roughly ₹12.75 lakh can end up with zero tax payable under the new regime, as reflected in this calculator.
How is income tax calculated under the new regime for FY 2025-26?
Taxable income is gross salary plus other income minus the ₹75,000 standard deduction. Tax is then computed across six bands used by this calculator: nil up to ₹4 lakh, 5% from ₹4–8 lakh, 10% from ₹8–12 lakh, 15% from ₹12–16 lakh, 20% from ₹16–20 lakh, 25% from ₹20–24 lakh, and 30% above ₹24 lakh. If taxable income is ₹12 lakh or below, the Section 87A rebate brings the tax payable to zero before the 4% Health and Education Cess is added.
How is income tax calculated under the old regime for FY 2025-26?
Taxable income is gross salary plus other income minus the ₹50,000 standard deduction and any eligible deductions you claim (Section 80C up to ₹1,50,000, HRA exemption, NPS 80CCD(1B) up to ₹50,000, health insurance under 80D, and home loan interest under Section 24(b)). Tax is then computed using the applicable slabs for your age group (general, senior 60–79, or super senior 80+), and a 4% Health and Education Cess is added on top.
What is the Section 87A rebate and who qualifies for it in FY 2025-26?
Section 87A gives eligible resident individuals a rebate that reduces their tax payable to zero if their taxable income is within a set threshold. For FY 2025-26, this calculator applies the rebate up to ₹5 lakh taxable income under the old regime, and up to ₹12 lakh taxable income under the new regime (as introduced in Budget 2025). Above these thresholds, tax is payable on the full computed amount.
Which regime should I choose — old or new?
There's no single correct answer — it depends on how much you can legitimately claim under the old regime's deductions versus the new regime's lower rates and higher rebate threshold. As a general rule of thumb, if your total eligible deductions (80C, HRA, NPS, 80D, home loan interest) are relatively modest, the new regime often results in less tax; if they're substantial, the old regime can still win. Enter your actual numbers into this calculator to see which applies to you — it is not personalized tax advice.
Can I switch between the old and new tax regime every year?
Salaried individuals with no business income can choose either regime each year when filing their return. Taxpayers with business or professional income can generally switch back to the old regime only once in their lifetime after opting for the new regime. The new regime is the default for FY 2025-26 — you must actively opt for the old regime if you want to use it.
What deductions can I claim under the old tax regime?
Common deductions modeled by this calculator include the ₹50,000 standard deduction, Section 80C investments up to ₹1,50,000, HRA exemption, NPS 80CCD(1B) up to ₹50,000, health insurance premiums under Section 80D, and home loan interest under Section 24(b) up to ₹2,00,000. Other deductions exist under Indian tax law that this calculator does not model — check with the official Income Tax Department portal or a tax professional for a complete list relevant to your situation.
Does the new tax regime allow any deductions?
The new regime allows very few deductions compared to the old regime. This calculator applies only the ₹75,000 standard deduction under the new regime — it does not model employer NPS contributions under 80CCD(2) or other narrow exceptions that may apply in your specific case. Confirm any additional deductions you may be eligible for with a tax professional or the official Income Tax Department resources.
What is the Health and Education Cess?
The Health and Education Cess is an additional 4% charge applied on top of the computed income tax (after any rebate) in both the old and new regimes. This calculator automatically adds it to arrive at your final tax payable.
Does this calculator work for countries other than India?
Yes. Switching the country dropdown recalculates using that country's rules: 2025 US federal tax with FICA and an optional state rate, 2025-26 UK tax with National Insurance, 2025-26 Australian tax with the Medicare levy and LITO, 2025 German income tax with Steuerklasse and Kirchensteuer, UAE's zero personal income tax, and Singapore's YA 2025 rates with CPF. The detailed guide, formula, and examples on this page focus specifically on India's old vs new regime.
How accurate is this calculator compared to my actual tax liability?
This calculator uses the slab rates, standard deductions, and rebate thresholds as used in its own logic for FY 2025-26, and is a close estimate for straightforward salaried income. It does not account for surcharge on very high incomes, capital gains, business income, arrears relief, or every deduction available under Indian tax law, so your actual liability calculated on the official Income Tax Department portal or by a chartered accountant may differ.
Is my salary and financial data safe when I use this calculator?
Yes. All calculations run locally in your browser using JavaScript. The salary figures, deduction amounts, and other details you enter are not transmitted to or stored on a server.
Is this income tax calculator free to use?
Yes, it's completely free with no signup, login, or payment required.
Can this calculator be used to file my income tax return?
No. This tool is designed for quick estimation and regime comparison, not for filing. Use the official Income Tax Department e-filing portal at incometax.gov.in, or consult a chartered accountant, to file an accurate, filing-ready income tax return.
How does age affect old-regime tax calculations in India?
The old regime gives a higher basic exemption limit to older taxpayers: ₹2.5 lakh for individuals below 60, ₹3 lakh for senior citizens (60–79), and ₹5 lakh for super senior citizens (80 and above). This calculator applies the correct exemption limit based on the age group you select; the new regime's ₹4 lakh nil-tax band applies uniformly regardless of age.
