How accurate is this compared to my payslip?
PayeTax estimates your pay using the selected tax year's rates. Your payslip can differ because of pay timing, pension arrangements, benefits in kind or employer-specific deductions. HMRC income tax rates.
Does it support Scottish tax rates?
Yes. Choose Scotland as your region and the calculator applies the Scottish income tax bands set by the Scottish Parliament, which differ from the rest of the UK. Revenue Scotland tax rates.
Does it work for self-employed or contractors?
No - PayeTax models PAYE for employees. Self-employed income is taxed through Self Assessment, which works differently. Our blog has guides, or use HMRC's Self Assessment tools directly.
What does the calculation include?
Income Tax, National Insurance, student loan repayments and pension contributions, broken down by pay period. Enter your pension contribution even for net pay or relief at source; we estimate it as salary sacrifice, which may overstate take-home. Pension arrangements explained.
Can I use it offline?
Yes. Install PayeTax as an app and it keeps working from cache when your connection drops. Install guide.
