Scottish income tax and Class 4 NI on every profit level from £12,000 to £100,000. Click any amount for a full breakdown.
A self-employed person in Scotland with £25,000 profit pays approximately £3,192 in tax for 2026/27 — £2,446 in Scottish income tax plus £746 in Class 4 National Insurance. Mandatory Class 2 NI was abolished from April 2024 and is no longer payable on self-employed profits above £7,105. The table below shows the full picture from £12,000 to £100,000 of annual profit.
The figures here use profit, not turnover. Profit is your business income after allowable expenses — things like business travel, equipment, professional fees, training, and a proportion of home-office costs. A freelancer billing £60,000 with £15,000 of legitimate expenses is taxed on £45,000 of profit, not the £60,000 of turnover.
Scotland sets its own income tax bands. For 2026/27 there are six — Starter, Basic, Intermediate, Higher, Advanced and Top — running from 19% to 48%, separate from the rest of the UK. The Personal Allowance of £12,570 is set UK-wide and is not devolved, so it still applies before any Scottish band kicks in.
Class 4 National Insurance is the only NI most self-employed people now pay, after mandatory Class 2 was abolished in April 2024. Self Assessment returns covering 2026/27 must be filed online by 31 January 2028, with any tax due paid on the same date.
What's new for 2026/27
| Annual profit | Income tax | Class 4 NI | Total tax | Monthly take-home | Effective | Marginal |
|---|---|---|---|---|---|---|
| £12,000 | £0 | £0 | £0 | £1,000 | 0% | 0% |
| £15,000 | £462 | £146 | £608 | £1,199 | 4.05% | 25% |
| £20,000 | £1,446 | £446 | £1,892 | £1,509 | 9.46% | 26% |
| £25,000 | £2,446 | £746 | £3,192 | £1,817 | 12.77% | 26% |
| £30,000 | £3,451 | £1,046 | £4,497 | £2,125 | 14.99% | 27% |
| £35,000 | £4,501 | £1,346 | £5,847 | £2,429 | 16.71% | 27% |
| £40,000 | £5,551 | £1,646 | £7,197 | £2,734 | 17.99% | 27% |
| £45,000 | £6,882 | £1,946 | £8,828 | £3,014 | 19.62% | 48% |
| £50,000 | £8,982 | £2,246 | £11,228 | £3,231 | 22.46% | 48% |
| £60,000 | £13,182 | £2,457 | £15,639 | £3,697 | 26.06% | 44% |
| £70,000 | £17,382 | £2,657 | £20,039 | £4,163 | 28.63% | 44% |
| £80,000 | £21,732 | £2,857 | £24,589 | £4,618 | 30.74% | 47% |
| £100,000 | £30,732 | £3,257 | £33,989 | £5,501 | 33.99% | 47% |
Class 4 NI: 6% on profits between £12,570 and £50,270, then 2% above. Class 2 NI was abolished from April 2024 — self-employed people with profits above £7,105 receive the National Insurance credit automatically without paying. Scottish income tax applied at 6-band rates for 2026/27. Marginal rate shows the combined Scottish income tax + Class 4 NI kept on the next £1 of profit at that level.
⚠ The £100k cliff edge
Self-employed profits between £100,000 and £125,140 lose £1 of Personal Allowance for every £2 of profit. Combined with the 45% Scottish Advanced rate and 2% Class 4 NI, this creates an effective marginal rate of roughly 69% — meaning you keep just 31p of every additional £1 earned. Pension contributions are the standard way to manage this. Read more: The Scottish 60% tax trap.
Class 4 NI is UK-wide; only income tax differs between Scotland and the rest of the UK.
| Annual profit | Scotland total tax | England total tax | Scottish surcharge |
|---|---|---|---|
| £25,000 | £3,192 | £3,232 | −£40 |
| £35,000 | £5,847 | £5,832 | +£15 |
| £50,000 | £11,228 | £9,732 | +£1,496 |
| £75,000 | £22,239 | £20,189 | +£2,050 |
| £100,000 | £33,989 | £30,689 | +£3,300 |
Scottish self-employed taxpayers pay more than their English equivalents at every profit level above roughly £33,500 — the point where Scotland's 21% Intermediate rate cancels out the £40 saved on the 19% Starter rate. The gap widens sharply once profit crosses the Higher rate threshold of £43,663. See our full Scotland vs England tax comparison or open the Scotland vs England Calculator to model your own income.
Self-employed people pay Class 4 NI at 6% / 2%; PAYE employees pay Class 1 NI at 8% / 2%. That gives the self-employed a small NI advantage at the same income level — before pension, holiday pay or sick pay are taken into account.
| Annual amount | PAYE take-home | Self-employed take-home | Difference |
|---|---|---|---|
| £25,000 | £21,559 | £21,808 | +£249 |
| £35,000 | £28,705 | £29,153 | +£449 |
| £50,000 | £38,024 | £38,772 | +£749 |
| £75,000 | £52,007 | £52,761 | +£754 |
These figures compare tax only, not the wider trade-offs of self-employment. PAYE employees usually receive employer pension contributions, paid holiday, statutory sick pay and redundancy entitlement — none of which self-employed sole traders get. Self-employed people, in turn, can deduct allowable business expenses from gross income before tax is calculated. Model an exact salary in our take-home pay calculator.
The low end (£12,000–£20,000 profit). The effective rate stays below 10% across this range. The £12,570 Personal Allowance covers the first slice tax-free, and Class 4 NI only kicks in at 6% on profit above £12,570. At £15,000 profit the total bill is just over £600 for the year — roughly 4% effective — and even at £20,000 the effective rate is around 8%. This is the band where most part-time freelancers, side-hustles and second incomes sit.
The middle band stretch (£20,000–£43,663). Two Scottish quirks bite here. First, the Basic rate band runs only to £29,526 in Scotland (versus £50,270 in England), so anything above that point hits the 21% Intermediate rate — a band that has no equivalent south of the border. Second, Class 4 NI is still 6% across this whole range. The combined marginal rate steps up from 25% to 27% as profit climbs, and the effective rate reaches around 16% by the time profit hits £43,000.
The Higher rate jolt (£43,663 onwards). Crossing into Scotland's Higher band pushes the income tax rate from 21% to 42% — a 21-point jump in a single pound. Combined with the still-6% Class 4 NI, the marginal rate hits 48%. Income above £50,270 drops back to 44% marginal because Class 4 NI falls to 2%, but the income tax rate stays at 42%. This is where the Scottish surcharge versus England becomes meaningful — typically £300 to £800 a year through this stretch.
The £100k cliff and beyond. From £100,000, the Personal Allowance starts tapering away at £1 lost for every £2 of extra profit, producing the punishing effective marginal rate flagged in the callout above. The Advanced rate (45%) applies from £75,001, and the Top rate (48%) from £125,141. The effective rate climbs from around 30% at £80,000 to nearly 40% at £150,000 — a steeper progression than anywhere else in the UK and the main reason high-earning Scottish self-employed people pay close attention to pension contributions.
On £30,000 profit, a Scottish self-employed person pays £4,497 in total tax for 2026/27: £3,451 in Scottish income tax (across the Starter, Basic and Intermediate bands) plus £1,046 in Class 4 National Insurance. That's an effective rate of 14.99% and a monthly take-home of £2,125. The figures rise with profit — see the table above for the full breakdown from £12,000 to £100,000.
No — mandatory Class 2 National Insurance was abolished from April 2024. Self-employed people with profits above the Small Profits Threshold (£7,105) automatically receive the qualifying year for State Pension purposes without paying anything. Voluntary Class 2 contributions of £3.65 a week (£189.80 a year) are still available for those below the threshold who want to maintain their NI record. At every profit level shown on this page, no Class 2 NI is due. Source: GOV.UK National Insurance guidance.
Turnover is your total business income before any deductions. Profit is turnover minus allowable business expenses — and that's what self-employed tax is calculated on. Common allowable expenses include business travel (45p per mile for the first 10,000 miles), a proportion of home office costs, equipment, professional fees, training, software, and accountancy. A graphic designer with £60,000 turnover and £15,000 of legitimate expenses would be taxed on £45,000 profit, not the £60,000 turnover. Read more in our self-employed tax guide.
Self Assessment deadlines apply UK-wide. For the 2026/27 tax year (running 6 April 2026 to 5 April 2027): you must register with HMRC by 5 October 2027, file paper returns by 31 October 2027, and file online returns and pay any tax owed by 31 January 2028. Missing the online deadline triggers an automatic £100 penalty, with daily penalties of £10 after three months. Read our Scottish Self-Assessment guide for the full timeline.
Payments on account are advance instalments toward next year's tax bill, due if your previous year's Self Assessment liability was more than £1,000. Each is 50% of the previous year's bill. They're due on 31 January (alongside the balancing payment for the previous year) and 31 July. In your second year of self-employment this can mean paying 150% of your first year's tax in January — a common cash-flow surprise. You can apply to reduce them if you expect lower profits, using form SA303 or the HMRC online service.
Yes, if your gross self-employed and property income is above £50,000 you must use Making Tax Digital for Income Tax Self Assessment (MTD for ITSA) from April 2026. The threshold drops to £30,000 from April 2027, and further reductions are planned. You'll need MTD-compatible software (FreeAgent, Xero, QuickBooks and others) to keep digital records and submit quarterly updates to HMRC, plus a final declaration. See our MTD for Scottish sole traders guide.
If your gross self-employed income for the tax year is £1,000 or less, you don't have to register with HMRC or file Self Assessment for that income. If it's between £1,000 and £85,000 (the VAT threshold), you can choose to claim a flat £1,000 trading allowance instead of working out your actual expenses. The allowance is most useful where actual expenses are very low — for example a tutor or writer with minimal overheads. If your real expenses exceed £1,000, you're better off claiming them instead. You can't claim both.
