What is this Income Tax Calculator?
This free income tax calculator estimates your tax liability, effective tax rate, and net income after tax for five countries — India, USA, UK, Canada, and Australia — with a complete bracket-by-bracket breakdown. For India, it supports both the Old Regime and New Regime for FY 2025-26 (AY 2026-27), including the new ₹12 lakh nil-tax threshold, surcharge and 4% Health & Education Cess, and handles all three age groups (below 60, senior citizen 60–80, super-senior above 80).
Unlike a simple tax estimator that just tells you a single number, this tool shows you the full calculation — exactly how much tax is charged in each slab, any applicable surcharge, the cess, and the final net income you take home. Since Budget 2025 made the New Regime far more generous, most taxpayers now pay less under it — but this breakdown lets you check your own numbers instead of guessing.
How to use this calculator — step by step
- Step 1 — Select your country: Choose India, USA, UK, Canada, or Australia. The input fields update to match that country's tax system.
- Step 2 — Enter your annual income: For India's New Regime, enter your taxable income after the standard deduction. For India's Old Regime, enter income after all your deductions (80C, HRA, etc.) since the calculator applies slabs directly to what you enter.
- Step 3 — Select regime (India only): Choose New Regime or Old Regime. If you are unsure, calculate both and compare — the result shows total tax for each.
- Step 4 — Select age group (India only): Below 60, Senior Citizen (60–80 years), or Super-Senior (above 80). Age affects the basic exemption limit under the Old Regime only — the New Regime slabs are the same for every age group.
- Step 5 — Click "Calculate tax": Instantly see your total tax liability, effective tax rate (tax ÷ income × 100), and net income (income minus tax). The full bracket table below shows every slab calculation.
- Step 6 — Read the bracket breakdown: Each row shows the income range, the rate applied to that slice, and the tax amount for that slice. The total at the bottom includes surcharge and cess where applicable.
- Step 7 — Compare regimes: Switch between Old and New Regime without changing your income to instantly see which saves you more tax.

India income tax — Old Regime vs New Regime for FY 2025-26, explained in full
India's New Tax Regime is the default regime — if you do not explicitly opt for the Old Regime, you are automatically taxed under the New Regime. Budget 2025 significantly overhauled the New Regime's slabs and rebate, so the two regimes now favor very different taxpayers than they used to. This calculator lets you compare both instantly with your real numbers.
India New Regime — tax slabs FY 2025-26 (Assessment Year 2026-27)
The New Regime slabs apply to all individuals regardless of age:
- Up to ₹4,00,000 — 0% (Nil)
- ₹4,00,001 to ₹8,00,000 — 5%
- ₹8,00,001 to ₹12,00,000 — 10%
- ₹12,00,001 to ₹16,00,000 — 15%
- ₹16,00,001 to ₹20,00,000 — 20%
- ₹20,00,001 to ₹24,00,000 — 25%
- Above ₹24,00,000 — 30%
Section 87A rebate under New Regime: If your taxable income is ₹12 lakh or below, you get a rebate of up to ₹60,000 — which fully cancels out the tax, making it ₹0. Just above ₹12 lakh, "marginal relief" kicks in so your tax never jumps by more than your income exceeds ₹12 lakh. Combined with the ₹75,000 standard deduction for salaried individuals, this makes gross salary up to ₹12.75 lakh effectively tax-free.
India Old Regime — tax slabs (unchanged for FY 2025-26)
Budget 2025 left the Old Regime untouched. It still has age-based basic exemption limits:
- Below 60 years: 0% up to ₹2.5L | 5% from ₹2.5L–₹5L | 20% from ₹5L–₹10L | 30% above ₹10L
- Senior Citizens (60–80 years): 0% up to ₹3L | 5% from ₹3L–₹5L | 20% from ₹5L–₹10L | 30% above ₹10L
- Super Senior Citizens (above 80 years): 0% up to ₹5L | 20% from ₹5L–₹10L | 30% above ₹10L
Section 87A rebate under Old Regime: Full rebate if taxable income (after all deductions) is ₹5 lakh or below — tax becomes ₹0. Standard deduction of ₹50,000 applies for salaried individuals.
Key differences — Old vs New Regime at a glance (FY 2025-26)
New Regime — best for
Most taxpayers, now that income up to ₹12.75 lakh is effectively tax-free for salaried employees. No HRA, 80C, LTA, or home loan interest deduction — but the much wider slabs and bigger rebate outweigh that for the majority of people, and filing is simpler with no proofs required.
Old Regime — best for
People with genuinely large deductions: significant HRA (living on rent in an expensive city), a home loan with substantial interest under Section 24(b), and full use of 80C (₹1.5L), NPS 80CCD(1B) (₹50K) and 80D. If these add up to several lakh, the Old Regime can still come out ahead.
There's no single break-even number
Because the exact break-even point shifts with your income level, there's no one deduction figure that works for everyone. The reliable way to check is to enter your real income in this calculator, switch between Old and New Regime, and compare the two totals directly.
A real comparison — ₹15 lakh income, Old vs New Regime
Enter ₹15,00,000 in the calculator and switch between regimes. New Regime: tax works out to ₹1,05,000 before cess (0% on the first ₹4L, 5% on ₹4–8L = ₹20,000, 10% on ₹8–12L = ₹40,000, 15% on ₹12–15L = ₹45,000), plus 4% cess = ₹1,09,200. Old Regime (assuming a fairly typical set of deductions — ₹50K standard deduction, ₹1.5L under 80C, ₹50K NPS, ₹25K under 80D — bringing taxable income down to ₹12.25L): tax works out to roughly ₹1,80,000 before cess, plus 4% cess = ≈ ₹1,87,200. In this example, the New Regime saves close to ₹78,000 — which is why it's now the better default for most people unless deductions are unusually high. Enter your own numbers to see your exact comparison.
Surcharge — when does it apply, and how does it differ by regime?
Surcharge is an additional tax levied on individuals with high income, calculated on the income tax amount (not income itself). It applies the same way up to ₹2 crore under both regimes, but the top slab differs:
- Income ₹50L–₹1 crore: 10% surcharge on income tax (both regimes)
- Income ₹1 crore–₹2 crore: 15% surcharge (both regimes)
- Income above ₹2 crore, New Regime: capped at 25% surcharge — the New Regime has no 37% slab
- Income ₹2 crore–₹5 crore, Old Regime: 25% surcharge
- Income above ₹5 crore, Old Regime: 37% surcharge
After adding surcharge, 4% Health & Education Cess is applied on the combined amount (tax + surcharge). This calculator applies the correct surcharge cap for whichever regime you select, and shows the surcharge and cess as separate rows in the bracket breakdown table.
How income tax is calculated in India — step by step
Step 1 — Gross Total Income: Sum of all income heads — salary, house property, capital gains, business/profession, other sources.
Step 2 — Deductions (Old Regime only): Subtract Chapter VI-A deductions (80C, 80D, 80CCD, 80TTA etc.) and the standard deduction (₹50,000) to arrive at Net Taxable Income.
Step 3 — Apply tax slabs: Tax is calculated progressively. Each rupee of income is only taxed at the rate of the slab it falls into — not the highest applicable rate on the entire income. This is how the bracket table in this calculator works.
Step 4 — Check Section 87A rebate and marginal relief: If taxable income ≤ ₹5L (Old Regime) or ≤ ₹12L (New Regime), tax becomes ₹0. Just above the New Regime's ₹12L threshold, marginal relief caps the tax so it never exceeds the amount by which income crosses ₹12L.
Step 5 — Add surcharge: If income exceeds ₹50 lakh, surcharge is added at the applicable rate for that regime.
Step 6 — Add 4% cess: Health & Education Cess = 4% × (tax + surcharge). This is the final income tax payable.

Income tax in USA, UK, Canada and Australia — quick guide
United States federal income tax (2023)
The US uses a progressive "marginal" tax system with 7 brackets: 10%, 12%, 22%, 24%, 32%, 35%, and 37%. The rate applies only to the portion of income within each bracket — not the entire income. The brackets differ by filing status. For a single filer earning $75,000: the first $10,275 is taxed at 10%, the next $31,500 at 12%, and the remaining $33,225 at 22%. Total federal tax ≈ $12,107. Effective rate ≈ 16.1%. This calculator covers federal tax only — US taxpayers also pay state income tax (0% in TX, FL, WA vs up to 13.3% in CA) which varies significantly by state.
The 4 filing statuses available in this calculator: Single (unmarried or legally separated), Married Filing Jointly (most common for married couples — usually lowest tax), Married Filing Separately (rare, used when one spouse has significantly higher income or debt issues), and Head of Household (unmarried with a qualifying dependent — better rates than Single).
United Kingdom income tax (2023-24)
UK residents get a Personal Allowance of £12,570 — income below this is tax-free. Above the allowance: Basic Rate 20% (up to £50,270 total income), Higher Rate 40% (£50,271 to £125,140), Additional Rate 45% (above £125,140). There is no tax-free Personal Allowance for income above £125,140 — it tapers away at a rate of £1 for every £2 earned above £100,000. A UK taxpayer earning £80,000 pays approximately £22,432 income tax with an effective rate of ~28%. Note: UK taxpayers also pay National Insurance contributions (NICs) which this calculator does not include — NICs add approximately 8–12% on employment income for most workers.
Canada federal income tax (2023)
Canada has 5 federal tax brackets: 15% (up to $53,359), 20.5% ($53,359–$106,717), 26% ($106,717–$165,430), 29% ($165,430–$235,675), and 33% (above $235,675). Canada also has a Basic Personal Amount of ~$15,000 which effectively makes the first ~$15,000 of income tax-free (as a non-refundable credit at 15%). This calculator shows federal tax only — Canadian taxpayers also pay provincial/territorial income tax which ranges from ~6% (Alberta) to ~21% (Nova Scotia) on higher incomes. A Canadian earning $80,000 pays approximately $13,879 federal tax with an effective federal rate of ~17.3%.
Australia income tax (2022-23)
Australia has a tax-free threshold of AUD $18,200, then progressive rates: 19% ($18,201–$45,000), 32.5% ($45,001–$120,000), 37% ($120,001–$180,000), and 45% above $180,000. Australian residents also receive a Low Income Tax Offset (LITO) of up to $700, which further reduces tax for lower income earners — this calculator shows the slab tax before offsets. An Australian earning $90,000 pays approximately $21,517 slab tax, with an effective rate of ~23.9% before offsets. Note: Australia's tax brackets have changed for later years — this calculator covers 2022-23 rates specifically.
Frequently asked questions
Which tax regime is better for me in FY 2025-26 — Old or New?
Since Budget 2025, the New Regime gives a full tax rebate on taxable income up to ₹12 lakh (₹12.75 lakh for salaried people, after the ₹75,000 standard deduction) — which makes it the better choice for the large majority of taxpayers, including many who previously benefited from the Old Regime. The Old Regime can still win, but generally only for people with substantial deductions: Section 80C investments (PPF, ELSS, NSC, home loan principal, LIC premium) up to ₹1.5 lakh, HRA exemption (if living on rent, often ₹1–4 lakh depending on city and salary), Section 80D health insurance premium up to ₹25,000 (₹50,000 for senior citizens), Section 80CCD(1B) NPS contribution up to ₹50,000, and Section 24(b) home loan interest up to ₹2 lakh. There's no single universal break-even number since it depends on your exact income level — the reliable way to check is to enter your income in this tool and compare both regimes directly.
What is the income tax slab under the New Regime for FY 2025-26?
The New Regime (default from FY 2023-24 onward) has 7 slabs for FY 2025-26: 0% 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. Key points: (1) These are the same for all age groups — no higher exemption for senior citizens. (2) Section 87A provides a rebate of up to ₹60,000, making taxable income up to ₹12 lakh effectively zero-tax, with marginal relief applying just above that line so tax doesn't jump sharply. (3) For salaried employees, a standard deduction of ₹75,000 is available, making the effective zero-tax threshold ₹12.75 lakh for salaried individuals. (4) The tax is calculated progressively on each slab — for taxable income of ₹14 lakh, the tax before rebate/cess is 0 (on first ₹4L) + ₹20,000 (on ₹4–8L at 5%) + ₹40,000 (on ₹8–12L at 10%) + ₹30,000 (on ₹12–14L at 15%) = ₹90,000, plus 4% cess = ₹93,600.
What deductions are allowed under the Old Regime but not the New Regime?
The New Regime removes most deductions in exchange for lower tax rates and a much larger rebate. Deductions not available under New Regime: Section 80C (PPF, ELSS, LIC, NSC, home loan principal) — up to ₹1.5L; HRA exemption (House Rent Allowance); LTA (Leave Travel Allowance) exemption; Section 80D (health insurance premium); Section 80E (education loan interest); Section 24(b) (home loan interest up to ₹2L for self-occupied); Section 80TTA/80TTB (savings account interest); and most other Chapter VI-A deductions. Deductions still available under New Regime: Standard deduction of ₹75,000 (for salaried/pensioners); Section 80CCD(2) — employer's NPS contribution (no cap); Agniveer Corpus deduction under 80CCH; gratuity and leave encashment exemptions. Because the New Regime's rebate is now so generous, even taxpayers who lose these deductions often still come out ahead unless their deductions are unusually large.
How accurate is this income tax calculator?
This calculator provides accurate estimates for standard salary income using the current FY 2025-26 tax slabs, surcharge rates, and cess for India, and current published brackets for the USA, UK, Canada and Australia. For India, it correctly applies the progressive slab system, age-based exemptions (Old Regime), the Section 87A rebate with marginal relief (New Regime), surcharge at the appropriate tier for each regime, and 4% cess. However, it does not account for: deductions (you need to enter income after deductions for the Old Regime, and after the standard deduction for the New Regime), capital gains (taxed differently — STCG and LTCG have separate rates), income from house property (net of loan interest), foreign income, or agricultural income. For complex tax situations — freelancers, business owners, NRIs, those with capital gains or rental income — please consult a qualified Chartered Accountant. This tool is for estimation and planning, not official ITR filing.
What is the deadline to file ITR in India, and how do I file officially?
For FY 2025-26 (AY 2026-27), the ITR filing deadline for most salaried individuals (ITR-1/ITR-2, no audit required) was 31 July 2026. If you missed it, a belated return can generally still be filed by 31 December 2026, along with a late fee under Section 234F (₹5,000, or ₹1,000 if income is below ₹5 lakh) and interest on any unpaid tax. For official ITR filing, always use the Income Tax e-Filing Portal at incometax.gov.in. You will need: PAN card, Aadhaar, Form 16 (from employer), Form 26AS and AIS (Annual Information Statement), and bank account details. Salaried individuals with income from one employer and no other income can typically file ITR-1 (Sahaj) — the simplest form. Use ITR-2 for capital gains or house property income, ITR-3 for business income. This calculator is not connected to the e-filing portal and cannot submit your ITR.
What is TDS and how does it relate to income tax?
TDS (Tax Deducted at Source) is income tax deducted by your employer (or bank, or payer) before paying you. For salaried employees, your employer deducts TDS every month from your salary based on your estimated annual tax liability (considering the regime you declare at the start of the year). The total TDS deducted appears in Form 16 (from employer) and Form 26AS (from the IT department). When you file your ITR, your actual tax liability is calculated, and if TDS deducted is more than your actual tax, you get a refund. If it's less, you pay the difference as self-assessment tax. Use this calculator to estimate your annual tax liability at the start of the year — if the number differs from what your employer is deducting, submit a revised tax declaration to your employer (typically done via investment proof submission in January–February).
Which countries does this calculator support, and what are its limitations per country?
