What is income tax?

Income tax is a tax you pay on your income. In the UK, it pays for public services like the NHS, education, and welfare.

How it works

Most employees pay tax directly through the Pay As You Earn (PAYE) system. Your employer automatically deducts it from your wages before it hits your bank account.

Tax bands overview

You pay different rates of tax on different parts of your earnings above your Personal Allowance (standard £12,570). As income increases, the rate applied to that upper band of income increases (20%, 40%, and 45%).

National Insurance

Alongside income tax, most workers pay National Insurance (NI) to qualify for certain benefits including the State Pension. This is calculated differently but also usually withdrawn automatically from your pay.

Common Mistakes

Confusing gross vs net salary

Gross is your total salary before taxes are applied. Net is your "take-home pay" after deductions. Don't plan your monthly expenses based on the gross figure.

Ignoring National Insurance

Many simple estimates forget National Insurance, which significantly reduces your actual take-home pay just like regular income tax.

Not adjusting for pension contributions

Workplace pensions reduce your taxable income, potentially keeping you under a higher tax band and altering how much deductions you actually receive.

Assuming same tax rate for all income

Only the income that falls within a higher band is taxed at that higher rate. Moving into the 40% band doesn't mean your entire salary is suddenly taxed at 40%.

Frequently Asked Questions

Your tax is calculated by applying different tax rates to specific income bands, after deducting your tax-free allowance.

In England, Wales, and Northern Ireland, the standard bands are: 0% up to £12,570, 20% on £12,571 to £50,270, 40% on £50,271 to £125,140, and 45% over £125,140.

Yes, it estimates standard employee Class 1 primary National Insurance contributions, normally deducted directly from employed income via PAYE.

This is an estimate. Individual circumstances like non-standard tax codes, student loans, or varying pension schemes will alter your true take-home pay.
