P11D
The form an employer uses to report benefits in kind after the end of the tax year, where those benefits are not payrolled.
Why it matters
HMRC then collects the tax by adjusting your code, which often produces a K code. Mandatory payrolling of most benefits is being phased in from April 2027.
Where you will see it
It arrives after the tax year ends, usually in July, and lists benefits your employer gave you that were not put through payroll.
What people get wrong
The tax on it is collected the following year through your code, which is why a benefit you had two years ago can still be affecting your pay today.

The same salary, by pay frequency
| Paid | Gross | Income tax | National Insurance | Take-home |
|---|---|---|---|---|
| Yearly | £45,000.00 | £6,486.00 | £2,594.40 | £35,919.60 |
| Monthly | £3,750.00 | £540.50 | £216.16 | £2,993.34 |
| 4-weekly | £3,461.54 | £498.92 | £199.48 | £2,763.13 |
| Fortnightly | £1,730.77 | £249.46 | £99.74 | £1,381.57 |
| Weekly | £865.38 | £124.73 | £49.87 | £690.78 |
Income tax across a full year is the same whichever row you are on. National Insurance is not quite, because it is worked out on each pay period in isolation rather than cumulatively — which is a small effect on steady pay and a larger one on irregular hours.
