Self-employed tax on £75,000: rest of the UK and Scotland
Scotland moves its sole traders into the advanced rate one pound above this profit, which makes pension relief unusually valuable here.
A sole trader with £75,000 of profit in England, Wales or Northern Ireland owes £20,189 for 2026/27, made of £17,432 Income Tax and £2,757 Class 4, and keeps £54,811. The same trader in Scotland owes £22,239, which is £2,050 more. That difference is about to grow faster. With the standard Personal Allowance, the Scottish higher rate of 42 % ends at £75,000 and the advanced rate of 45 % takes over from £75,001, so the next pound of Scottish profit costs 47 % with Class 4, against 42 % elsewhere. Pension contributions are worth looking at closely at this level. Every gross pound paid into a personal pension comes off the top slice of income, so relief runs at the higher rate in the rest of the UK and at 42 % or more in Scotland, while Class 4 is left unchanged.

The last pound of the Scottish higher band
Scotland has six Income Tax rates, against three in the rest of the UK, and the fifth one starts here. Taxable income above £62,430, which means £75,001 of profit once the Personal Allowance is added back, is charged at 45 %. It runs all the way to £125,140, where the top rate of 48 % begins. A Scottish architect who finishes the year on £75,000 has used up the higher band to the pound. A good final quarter would be taxed at 45 % instead of 42 %, before the 2 % Class 4 that applies on all profit above £50,270.
What a pension contribution really costs at this profit
Relief at source works in two steps. The provider adds the basic 20 % to what you pay, and the tax return gives back the rest of the rate charged on the slice of income the contribution covers. In the rest of the UK that slice is taxed at 40 %; in Scotland at 42 %, so the extra relief there is a little larger. Class 4 is charged on profit and does not change. The table puts numbers on four contribution sizes.
| Gross contribution | You pay the provider | Bill cut rUK | Real cost rUK | Bill cut Scotland | Real cost Scotland |
|---|---|---|---|---|---|
| £2,000 | £1,600 | £400 | £1,200 | £440 | £1,160 |
| £5,000 | £4,000 | £1,000 | £3,000 | £1,100 | £2,900 |
| £10,000 | £8,000 | £2,000 | £6,000 | £2,200 | £5,800 |
| £15,000 | £12,000 | £3,000 | £9,000 | £3,300 | £8,700 |
All four sizes fit inside the slice of profit taxed at the higher rate, so the cost per pound is the same in every row. Higher-rate relief would run out only for contributions beyond £24,730 in the rest of the UK, or £31,338 in Scotland. The pension relief calculator works out the cut for any profit and any amount.
A border gap that widens from here
At £75,000 a Scottish sole trader pays £2,050 more than one in Newport or Newry. Up to this point the difference grew by 2 % on each pound of higher-rate profit; past £75,001 it grows by 5 %. At £90,000 of profit the gap is £2,800. The Scottish tax page sets the bands side by side.
Instalments and the Child Benefit charge
A business that is settled at this level pays two instalments of £10,094, on 31 January 2028 and 31 July 2028. Parents should add the High Income Child Benefit Charge: at £75,000 of adjusted net income, 75 per cent of the year's benefit is repaid, £1,753 for two children, and the whole of it goes at £80,000. The pension contributions above also reduce that charge.
