Tax on Second Jobs
It's a common misconception that you pay 'more tax' on a second job.
All employees in Guernsey have a tax coding which gives you a certain allowance tax‑free. For 2024, the standard allowance is 267/1158, meaning the first £267 per week or £1,158 per month (depending on your pay cycle) is tax free. Social Security is assessed separately.
However, your allowance can only be applied to your "main" job.
Say you earn £500 a week. You'll be taxed nothing on the first £267, and 20% on the remaining £233 — so £46.60 tax.
If that £500 is split between two jobs, one paying £400 and one paying £100, you'd pay nothing on the first £267 of Job One and 20% on the remaining £133 (£26.60). At Job Two you'll pay 20% on the whole £100 (£20).
£26.60 + £20 = £46.60. The total tax is the same.
If you believe you are not paying the right amount of tax, email payroll@tcs.gg and explain why. Emails like "my tax is wrong fix it please" can't be actioned — please be descriptive.
