How UK Income Tax is calculated
UK Income Tax is usually calculated by taking your gross income, applying your Personal Allowance, then taxing the remaining income across the relevant tax bands. Most people pay no Income Tax on income covered by their Personal Allowance.
Income Tax bands
After your Personal Allowance, taxable income is normally split into bands. Income in each band is taxed at that band’s rate, which means only the income above a threshold is charged at the higher rate.
Self-employed income tax
Self-employed workers usually calculate Income Tax on annual profits rather than salary. This calculator can estimate tax on self-employed profits, but business expenses, payments on account and other Self Assessment details may affect your final bill.
Income Tax vs take-home pay
Income Tax is only one deduction from your income. National Insurance, pension contributions and student loan repayments can also affect your final take-home income.
