Marginal relief
Your tax is always worked out to see if you benefit from marginal relief.
Calculating your tax bill
The marginal tax calculation
Exempt from tax
If your income is below the total of your tax exemption threshold and any other tax deductions you won't pay any tax.
Paying tax at the marginal rate
If your income is over the total of the exemption threshold and any other deductions you'll pay tax but you'll get marginal relief if the marginal rate calculation works out less than the standard rate calculation. You'll get less marginal relief as your income increases.
Maximum tax rate
You'll never pay more than 20% personal tax on your total income in the year.
