Why your payslip may differ from an online estimate
Payroll calculations can vary because of tax codes, cumulative pay, bonuses, benefits, salary sacrifice, pension deductions and student loan timing. A calculator gives an estimate, not a final payroll calculation.
When should salary tax be reviewed?
You should consider a review if your tax code changed, your income increased, you have multiple jobs, you receive benefits in kind, your salary is over £100,000, or you think too much tax has been deducted.
