All income tax, payroll taxes and business taxes are based on the latest UK tax tables and tax law provided by HMRC (Her Majesty's Revenue & Customs). HMRC is responsible for taxation on the UK and runs the tax year from 6th April to 5thApril the following year, for example 6th April 2024 to 5th April 2025. You can check the latest UK tax rates and thresholds used in our online tax and salary calculators if you wish to validate or query a specific tax rate, threshold or allowance.

Each tax calculator, salary calculator and salary example etc. includes a breakdown of how to calculate the specific tax applied or allowance used and has the full workings out as well as guides on the tax formula used.

You can then of course complete your own UK salary and tax calculations or access the free online calculators on iCalculator whenever you need them in the future or compare your salary the to the average salary in the UK in 2024.

UK Employee Payroll

Most income tax in the UK is deducted using the Pay As You Earn (PAYE) system. PAYE works by calculating an annualised salary based on your payroll period and taxable income for that period. Deductions are then taken in equal amounts each and every time you are paid, the aim being to provide tax payments to HMRC quickly and balanced over the financial year for the employee. The employee payroll section includes salary calculators, guides and examples that provide a clear illustration of payroll deductions and options for reducing the amount of PAYE income tax paid by using legal income tax avoidance opportunities such as salary sacrifice.
