Is overtime pay taxable in the UK?
Yes, overtime pay is fully taxable. It's added to your regular earnings and taxed at your marginal rate. If overtime pushes you into a higher tax band (over £50,270), that portion is taxed at 40%.
What is time and a half overtime?
Time and a half means you're paid 1.5 times your normal hourly rate. For example, if you earn £15/hour, time and a half would be £22.50/hour. This is a common rate for weekend or evening overtime.
Is my employer legally required to pay overtime?
There's no legal requirement to pay enhanced overtime rates in the UK. However, your average hourly pay (including overtime) must not fall below the National Minimum Wage. Many employers offer enhanced rates as a benefit.
How does overtime affect my pension contributions?
If you're in an auto-enrolment pension scheme, overtime may be included in pensionable earnings, depending on your scheme rules. This increases both your contributions and your employer's contributions.
Will overtime affect my tax code?
Regular overtime shouldn't change your tax code, but it may affect your total tax paid. If HMRC thinks you'll earn significantly more, they might adjust your tax code to collect tax more evenly throughout the year.
