Scotland's 48% Top Rate Above £125,140: What It Costs in 2026/27
How Scotland's 48% top rate of income tax applies above £125,140 in 2026/27, how it compares with the rUK 45% additional rate, and a worked example.
Scotland's Top Rate vs the rUK Additional Rate
| System | Rate above £125,140 |
|---|---|
| Scotland (top rate) | 48% |
| Rest of UK (additional rate) | 45% |
| Gap | 3 percentage points |
Worked Example: £150,000 Income
| Slice of income | Scottish rate | rUK rate | Difference |
|---|---|---|---|
| Above £125,140 (£24,860 in this example) | 48% | 45% | 3 points |
| Tax on that slice | £24,860 × 48% = £11,932.80 | £24,860 × 45% = £11,187.00 | £745.80 more in Scotland |
This is only the difference on the top-rate slice — the overall gap between Scottish and rUK tax bills also depends on how the lower bands (intermediate, higher/advanced) compare across the rest of the income.
The Personal Allowance Taper Makes £100k-£125,140 Even Costlier
| Threshold | Effect |
|---|---|
| £100,000 | Personal Allowance starts reducing by £1 per £2 of income above this |
| £125,140 | Personal Allowance fully withdrawn; top/additional rate begins |
Because losing Personal Allowance effectively taxes an extra slice of income at the band rate that would otherwise have been tax-free, the effective marginal rate between £100,000 and £125,140 is commonly estimated at well above the headline rate for both Scottish and rUK taxpayers — a bracket often nicknamed the "60% (or higher) tax trap".
Reducing Exposure Through Pension Contributions
Personal pension contributions reduce adjusted net income, which can restore some Personal Allowance (if it pulls income below £125,140) or avoid the taper altogether (if it drops income below £100,000) — for high earners near these thresholds, this is often one of the most tax-efficient uses of spare income, though the tapered annual allowance rules for pension contributions also need checking at very high income levels.

What is Scotland's top rate of income tax in 2026/27?
48%, applying to all taxable income above £125,140 — 3 percentage points higher than the 45% additional rate that applies above the same threshold in the rest of the UK.
Why does the Personal Allowance disappear at £125,140?
The £12,570 Personal Allowance is reduced by £1 for every £2 of income above £100,000, and is fully withdrawn once income reaches £125,140 — this rule is UK-wide and applies identically in Scotland, creating an effective marginal rate well above the headline band rate between £100,000 and £125,140.
How much extra does a Scottish taxpayer on £150,000 pay compared with rUK?
On income above £125,140, the rate difference is 3 percentage points (48% vs 45%). On the £24,860 of income between £125,140 and £150,000, that's an extra £745.80 a year in Scotland compared with the rUK equivalent, before accounting for differences lower down the band structure too.
What is the effective marginal rate between £100,000 and £125,140 in Scotland?
It's higher than the headline advanced rate of 45% because the Personal Allowance taper effectively adds extra tax on top — many advisers estimate the effective marginal rate in this band at around 67% or more for Scottish taxpayers, though the exact figure depends on which band the income otherwise falls into.
Does the additional rate threshold in Scotland move with Personal Allowance changes?
The £125,140 threshold (where the Personal Allowance is fully withdrawn and the top/additional rate begins) is set UK-wide and has been frozen since 2023, alongside the frozen £100,000 taper-start threshold — both apply identically whether taxed under rUK or Scottish rates.
Can pension contributions help reduce exposure to the 48% top rate?
Yes, for many high earners — personal pension contributions reduce adjusted net income, which can pull income back below £125,140 (restoring some Personal Allowance) or below £100,000 entirely, and any income kept out of the top/additional rate band saves tax at the highest marginal rate that would otherwise apply. Get personalised advice given the tapered annual allowance also applies to very high earners.
Is the 3-point gap between Scottish and rUK top rates likely to change?
The Scottish and UK Governments set their respective rates independently each year via their own Budgets, so the gap can widen, narrow or stay the same — check the latest Scottish Budget and UK Autumn Budget/Spring Statement for any changes in future years.
Does the top rate apply to savings and dividend income for Scottish residents?
No — the Scottish bands, including the 48% top rate, apply only to non-savings, non-dividend income. Savings interest and dividends for Scottish residents are still taxed using UK-wide savings and dividend tax rates, including the 39.35% additional dividend rate.
