05 How it works
Salary, self-employed income, or both — yearly, monthly or weekly. Nothing leaves your browser.
Personal allowance, tax bands for where you live, National Insurance, student loans and pension relief.
Take-home by the month, week or year, plus what the self-employed owe HMRC and when.
You count income when the money arrives and expenses when you pay them — not when an invoice is sent. It’s the default for most sole traders and subcontractors.
With HMRC’s simplified rates: a flat amount per business mile covering fuel, repairs, insurance and wear, claimed instead of your actual vehicle costs.
Up to £1,000 of self-employed income is tax-free. You can use it instead of your expenses, not as well — we pick whichever is better for you.
What employees pay through PAYE: 8% on pay between £12,570 and £50,270, then 2% above.
What the self-employed pay on profits: 6% between £12,570 and £50,270, then 2% above. It’s paid through Self Assessment with your income tax.
Workplace pensions come off your pay before income tax. For a personal pension you pay 80% and the government adds 20%; higher-rate relief comes back through Self Assessment.
Every rate for 2026/27 was checked against gov.uk on 23 September 2026.
An estimate for guidance only — not tax, legal or financial advice, and not connected to HMRC. Tax is worked out over the whole year, so month-to-month payslips can differ, especially around bonuses. It doesn’t cover limited companies, partnerships or landlords, dividends, savings or rental income, salary sacrifice, Marriage Allowance, capital allowances, trading-loss relief against other income or voluntary National Insurance for time abroad. For your own situation, speak to an accountant.
Good decisions start with a clear picture.
