Scotland's £100k trap: 69.5% marginal tax, but no childcare cliff
Scotland sets its own income tax on earnings, and in 2026/27 it runs six bands where the rest of the UK has three:
| Band | Rate | Income (full allowance) |
|---|---|---|
| Starter | 19% | £12,571 – £16,537 |
| Basic | 20% | £16,538 – £29,526 |
| Intermediate | 21% | £29,527 – £43,662 |
| Higher | 42% | £43,663 – £75,000 |
| Advanced | 45% | £75,001 – £125,140 |
| Top | 48% | over £125,140 |
National Insurance, student loan thresholds, child benefit and the £100,000 adjusted-net-income line are not devolved — they’re the same everywhere. What changes is what happens when you cross the line.
The taper is harsher in Scotland
The personal allowance withdrawal — £1 lost per £2 over £100,000 — interacts with the 45% advanced rate instead of 40%. Each extra £100 in the zone costs £45 on the pay itself plus £22.50 on the newly-taxed allowance plus £2 NI: 69.5p in every £1, against 62p in England. With a Plan 4 student loan it’s 78.5p. The mechanics are the same as the rUK 60% trap — just crueller.
The childcare cliff is shallower — deliberately
Scotland’s 1,140 hours of funded early learning and childcare are universal: there is no work requirement and no £100,000 test, so crossing the line does not take your funded hours away. What you do still lose, instantly and in full, is Tax-Free Childcare — the 20% top-up (worth up to £2,000 per child a year) is UK-wide and keeps its cliff.
So a Scottish parent of two paying £15,000 of nursery costs faces roughly a £3,000 overnight loss at £100,001, where an English parent in the same position loses about £8,000 (see the childcare cliff). Smaller — but stacked on the 69.5% taper it still makes the £100k–£125k zone a terrible place for a Scottish parent’s income to sit.
The child benefit charge applies in Scotland unchanged: 1% per £200 between £60,000 and £80,000 of the higher earner’s income — though because that window is taxed at 42% rather than 40%, the combined marginal rate is a couple of points higher than down south.
The fix is the same — and relief is slightly richer
Pension contributions reduce adjusted net income £1 for £1 whatever the type, and in Scotland the income tax relief runs at your 42/45/48% rates, so each sacrificed pound in the taper zone costs even less take-home than in England. Salary sacrifice remains the best route (it also saves NI and any student loan); bonus sacrifice works identically.
