Bonuses and commission
Cash bonuses, including vouchers exchangeable for cash, count as earnings. The employer adds them to other earnings and deducts PAYE Income Tax and Class 1 National Insurance. Commission and other money payments derived from employment are also employment earnings.
A cash bonus does not have a separate payroll tax rate: it is added to other earnings. Because Income Tax is progressive, a larger payment can move part of taxable income into a higher band without all earnings being taxed at that higher rate. See how Income Tax works for the wider calculation.
Why deductions can jump
Payroll uses the tax code, pay period and cumulative position. A bonus can push taxable income into a higher band without all salary becoming taxed at that rate. National Insurance uses separate period thresholds.
Check gross bonus, taxable pay, code and year-to-date totals rather than estimating tax by multiplying the bonus alone by one rate.
Non-cash bonuses
Non-cash items follow the reporting and payment rules for the specific item. PAYE can apply where an item is readily convertible to cash.
Ask the employer how the item was valued and reported. “Gift” on an internal memo is not a tax classification.
Tips and troncs
All tips are subject to Income Tax. National Insurance depends on how the customer paid, how the tips are managed and the employer’s involvement in allocating them.
Direct tips kept by a worker must be reported to HMRC through Self Assessment, the personal tax account or by phone. National Insurance is not due on direct tips reported through this route.
Tips passed through an employer or workplace tronc are taxed through pay. Whether National Insurance is due depends on the employer’s involvement in sharing them.
Keep a daily or weekly record of direct tips rather than reconstructing them at year end.
Service charges
A compulsory service charge passed to staff is treated like wages. A voluntary service charge follows the tax and National Insurance treatment for tips.
The customer payment label and the employer’s distribution arrangement both matter. Check the payslip and tronc statement.
Reconcile variable pay
- Obtain the bonus, commission or tronc statement and read your payslip alongside it.
- Match gross pay on the payslip.
- Check whether the item is cash or non-cash.
- Identify compulsory or voluntary service charge.
- Review tax, National Insurance, pension and loan deductions separately.
- Compare the code with HMRC.
- Keep direct-tip records and report where required.
A worked payroll check
Suppose a monthly payslip contains ordinary salary, a one-off cash bonus and an amount distributed by a tronc. Start with the gross figures: confirm that all three amounts shown on the supporting statements appear in taxable pay where the payroll treatment requires it. Then review Income Tax, National Insurance and any pension or student-loan deductions as separate calculations. A lower net bonus does not, on its own, show that payroll used a special bonus rate.
Next compare the tax code and year-to-date taxable pay with the previous payslip. A cumulative code may recalculate tax using the year-to-date position, while a non-cumulative code works differently. The correct response is therefore to reconcile the figures and code, not to infer an error from the change in net pay alone. If a direct cash tip is absent from payroll, preserve the tip record and follow HMRC’s reporting guidance rather than adding it informally to a later payslip.
Common mistakes
- Assuming a bonus has a special flat tax rate.
- Treating all tips as tax-free cash gifts.
- Ignoring direct tips outside payroll.
- Calling a compulsory service charge a voluntary tip.
- Confusing Income Tax with National Insurance.
- Looking only at net pay.
What to do next
- Check the variable-pay statement and payslip.
- Confirm distribution and benefit treatment.
- Record direct tips.
- Compare year-to-date pay and tax.
- Update HMRC if employment records or income estimates are wrong.
