Common questions
Is overtime taxed at a higher rate?
No. Overtime is taxed at your marginal rate, the same as the rest of your pay. It can feel higher because the extra income may push you into the next tax band for that period, or trigger a larger student loan / NI deduction. Annually it averages out at your normal rate.
How is time-and-a-half calculated?
Time-and-a-half is your normal hourly rate multiplied by 1.5. For example at £15/hour, an overtime hour pays £22.50 gross. Apply your marginal income tax rate (20 or 40 percent), NI (8 or 2 percent), and any student loan or pension to see what lands.
Will overtime affect my tax code?
Generally no. Tax codes change based on your full-year income forecast, not on a single overtime month. If your overtime is regular and pushes you into higher rate territory year-round, HMRC may eventually adjust your code, but a one-off month should not.
Does overtime count for pension auto-enrolment?
It depends on your employer's definition of qualifying earnings. Most schemes include overtime up to the £50,270 upper limit. Check your scheme rules; if overtime is excluded, your pension contribution stays flat regardless of overtime.
