Income Tax Calculator

How do I use the income tax calculator?

1. Choose a Country: United States, United Kingdom, India, Canada or Australia. The currency changes to match.
2. Enter your Annual Gross Income, your total yearly income before tax.
3. If you have them, add Additional Deductions. The country’s standard deduction, allowance or credit is already included, so enter only extra amounts.
4. Read the Tax Breakdown by Bracket and the Tax Summary: total deductions, taxable income, total income tax, effective rate, and annual and monthly take-home pay.

Results update as you type, and you can save or share a scenario.

How do tax brackets work?

The calculator uses progressive brackets. Your taxable income is split into bands, and each band is taxed at its own rate.

Moving into a higher bracket doesn’t raise the tax on all your income. Only the part above the threshold is taxed at the higher rate; everything below it is taxed exactly as before. In this model, earning more never leaves you with less after income tax.

What does the calculator show for $75,000?

This is what the calculator shows for the United States at $75,000 gross income (its starting value) with no additional deductions. It uses IRS brackets and the $16,100 standard deduction for a single filer, federal income tax only. It’s a simplified model, so your result will differ.

Taxable income = $75,000 − $16,100 = $58,900

• Total income tax: 1,240 + 4,560 + 1,870 = $7,670.00
• Effective rate: 7,670.00 ÷ 75,000 = 10.23%
• Marginal rate: 22%, the top band reached
• Take-home pay: 75,000 − 7,670.00 = $67,330.00 a year, about $5,610.83 a month

What does this calculator include and leave out?

Included:

• Income tax brackets and each country’s standard deduction, allowance or credit, plus India’s 87A rebate and 4% cess
• Any additional deductions you enter

Data years used:

• United States: 2026 IRS brackets and standard deduction ($16,100), single filer
• United Kingdom: 2026–27 HMRC bands (England, Wales and Northern Ireland), with the personal allowance taper above £100,000

• Australia: 2026–27 ATO resident rates, tax-free threshold applied once, Medicare levy not included

Each label names the tax year for that country.

Treat the result as an estimate only, and check current figures with the official source: IRS, HMRC (GOV.UK), Income Tax Department (India), CRA, ATO.

What is the difference between effective and marginal tax rate?

Your marginal rate is the rate on your last dollar of taxable income: the highest band in the breakdown. Your effective rate is total income tax divided by gross income, which the calculator shows under Total Income Tax.

In the example, the marginal rate is 22% but the effective rate is 10.23%, because most income falls in lower bands and the standard deduction isn’t taxed.

The calculator doesn’t show the marginal rate separately; read it from the top band in the breakdown.
