💰 Tax Calculator

1. Enter your gross income (the full amount before tax) and select the currency if needed.
2. Enter the tax-free allowance — the portion of income on which you pay no tax.
3. Enter the flat tax rate as a percentage (for example 20 for 20%).
4. Press the Calculate button to see the results.
5. Read the taxable income, the tax owed and your net after-tax income.

Is this an official tax calculation?

No. This tool provides a quick estimate using a single flat tax rate, which is ideal for budgeting and comparisons. Real tax systems usually use progressive brackets where different portions of income are taxed at different rates, plus credits and deductions. For an official figure, consult your local tax authority or a qualified accountant.

What is the tax-free allowance?

The tax-free allowance (sometimes called a personal allowance or standard deduction) is the portion of your income on which you pay no tax. Only the income above this amount is taxed. If your income is below the allowance, your tax owed is zero.

Can I use any currency?

Yes. The calculation is purely numerical, so you can enter amounts in any currency you like — dollars, euros, pounds, yen or anything else. Just keep the currency consistent across all three fields, since mixing currencies would give a meaningless result.

Why is my net income higher than expected?

If your gross income is below the tax-free allowance, the taxable income is zero and you owe no tax, so your net income equals your gross income. Also double-check the tax rate — entering 0.20 instead of 20 would apply a rate of 0.2 percent instead of 20 percent, which is a common mistake.

Remember that this tool uses a single flat rate, so for a quick progressive estimate you can run it twice: once on the portion of income in a higher bracket and once on the lower portion, then add the taxes together. Always enter the tax rate as a whole-number percentage (20 for 20 percent), not as a decimal, to avoid the common error of under-reporting the tax by a factor of 100. The tax-free allowance has a powerful effect: raising it reduces tax owed far more than an equivalent cut in the rate for anyone near the threshold. Keep in mind that real take-home pay also depends on social-security contributions, retirement contributions and other deductions that this simple model does not include. For comparing two job offers, run each salary through the calculator with the same allowance and rate to see the difference in net income at a glance.
