A bonus can push adjusted net income above £100,000 even if salary alone does not. The real question is the ANI gap after reliefs, not the bonus headline on its own.
Worked examples
These examples focus on the “did the bonus cause it?” question that most readers actually have.
Base pay £96,000, bonus £3,000
You may still stay under the line. If there are no other taxable amounts pushing ANI higher, the threshold might not be crossed.
Why it matters: not every bonus automatically triggers the taper.
Base pay £98,000, bonus £5,000
ANI can move above £100,000. A relatively modest bonus can be enough once it sits on top of already-high income.
Why it matters: the key number is the total ANI after the bonus lands.
Base pay £101,000, no bonus
The taper may already be live. Sometimes the bonus gets the blame when the ANI problem already existed.
Why it matters: this page helps separate the bonus effect from the baseline issue.
Base pay £99,000, bonus £6,000, pension contribution
You may be able to get back to around the line. A qualifying gross pension contribution can offset the ANI impact of the bonus.
Why it matters: once you know the gap, the planning question becomes much clearer.
Why this page exists
Many people already know the broad £100,000 rule. What they really want to know is whether the bonus is the moment the rule bites.
The bonus matters only because it changes ANI
This page isolates the before-and-after picture so you can see whether the bonus is what pushes you over £100,000 or whether you were already in the taper zone for another reason.
Measure the gap to £100,000, not just the size of the bonus
If you are already very close to the line, a small bonus can matter a lot. If you are well below it, the same bonus may not change the answer at all.
What can make the bonus matter more
- Existing ANI already near £100,000
- Taxable benefits and other income
- Forgetting the taper uses ANI
What can soften the impact
- Qualifying gross pension contributions
- Grossed-up Gift Aid
- Checking the true ANI gap first
What to do next if the bonus tips you over
These are the follow-up checks that usually matter once you know the bonus probably changed the threshold position.
Assuming the bonus alone caused the issue
Sometimes the bonus is only the visible piece. Taxable benefits, savings income or a pre-existing ANI above the line can already have started the taper.
Ignoring the relief side of the calculation
If the bonus pushes ANI only slightly over £100,000, a pension contribution can sometimes reverse the threshold outcome.
Compare the bonus page with the pension and ANI pages
That gives you the cleanest next-step answer: how far over the line you are, whether the bonus is really the trigger, and what gross pension amount might change the result.

Questions people usually ask
Can a bonus push me over £100,000 even if salary does not?
Yes. The relevant test is ANI, so a bonus can be enough to move you into the taper zone.
What if I was already over the line before the bonus?
Then the bonus may worsen the position, but it is not the original trigger. This page helps separate those two things.
Can pension contributions offset the bonus effect?
Often yes. A qualifying gross pension contribution can reduce ANI and may bring you back to or below the threshold.
