What's different at £100,000
The things that only apply at this salary, worked out with its numbers.
- 1
You're exactly on the line. Adjusted net income of £100,000 keeps everything; £100,001 loses it.
- 2
Any bonus, however small, now crosses the line unless it goes into your pension. Agree a bonus sacrifice with payroll before the bonus is paid.
- 3
The allowance taper starts at the same line, so a raise from here is taxed at 62% before you count the childcare.
- 4
A £2,000 sacrifice (£167 a month) buys a buffer for savings interest and small pay changes, at a take-home cost of £1,160.

Scenarios at £100,000
Children under 5, a buffer under the line, and what a rise from here is worth.
By children under 5
| Children under 5 | Cash a year | Child Benefit charge | Childcare support |
|---|---|---|---|
| None | £68,557 | — | — |
| One child | £68,557 | −£1,407 | £10,550 |
| 2 children | £68,557 | −£2,337 | £21,100 |
Cash is take-home plus Child Benefit less the charge. Childcare support is Tax-Free Childcare plus funded hours, each child 9 months to 2 years old.
Buffers under £100,000
| Target | Sacrifice a year | A month | Take-home change | Into your pension |
|---|---|---|---|---|
| £98,000 (£2,000 buffer) | £2,000 | £167 | −£1,160 | +£2,000 |
| £95,000 (£5,000 buffer) | £5,000 | £417 | −£2,900 | +£5,000 |
A buffer covers income you can't control before 5 April: a bonus, savings interest, a benefit in kind. Through a personal pension instead, pay in 80% of the sacrifice and the provider grosses it up.
Your next £1,000, £5,000 and £10,000

After income tax, NI and the Child Benefit charge. The one-child column also counts childcare support lost or kept when the extra crosses £100,000, which is why it can go negative.

Assumptions
One earner, England, Wales or Northern Ireland rules for 2026-27, salary only, no pension and no student loan. Childcare figures assume each child is 9 months to 2 years old and in nursery enough to use the full Tax-Free Childcare top-up; funded hours are valued at £7.50 an hour. These are England childcare scenarios assuming all other eligibility conditions are met. Children with universal 15 hours retain those hours above £100,000; use the calculator to include them.
