Common questions

How is my take-home pay calculated?

Your gross salary has income tax, National Insurance and any pension or student loan deducted. Income tax uses your personal allowance (£12,570 for most people in 2026/27) and the 20%, 40% and 45% bands; National Insurance is charged separately on your earnings. The take-home pay calculator does it all for your salary.

How much tax do the self-employed pay?

Sole traders pay income tax on their profit using the same bands as employees, plus Class 4 National Insurance, and may make payments on account towards the next year. There’s no employer doing it for you, so it’s settled through Self Assessment. The self-employed tax calculator estimates the bill.

What is the personal allowance for 2026/27?

The standard personal allowance is £12,570 — the amount you can earn before paying income tax. It’s reduced by £1 for every £2 you earn above £100,000, disappearing entirely at £125,140. Scotland uses the same allowance but different tax bands above it.

How does salary sacrifice save tax?

You give up part of your gross salary in exchange for a benefit — usually pension contributions. Because the sacrifice comes out before tax and National Insurance, you pay less of both, so more of your money ends up working for you. The salary sacrifice guide explains the trade-offs.
