Is a limited company still worth it for associates in Scotland?

Our article on whether a limited company is still worth it for associates in 2026 ran the numbers for an illustrative associate on £120,000 of fully private, fully drawn profit and found the company £2,257 worse off than staying a sole trader. That piece was explicit that its figures were for England. Here is why that caveat matters: rerun the same associate as a Scottish taxpayer and the sole-trader side gets materially more expensive, while the company side does not move at all.

Where you live decides which bands apply — not where you practise

Scottish Income Tax applies to you if your main home is in Scotland for most of the tax year. It has nothing to do with where your surgery sits, who your NHS board is, or where your practice company is registered. An associate who lives in Berwick-upon-Tweed and drives to a chair in Edinburgh is not a Scottish taxpayer; one who lives in Gretna and commutes to Carlisle is. It is worth checking this directly rather than assuming — cross-border commuting is common in dentistry, and the wrong assumption here changes every figure below.

The 2026/27 position, stated plainly

The Scottish Parliament sets the rates and bands that apply to non-savings, non-dividend income — essentially your salary, self-employment profit and rental income. Everything else that touches this comparison is reserved to Westminster and is identical in Scotland and England. For 2026/27:

• Scottish Income Tax — six bands, confirmed at the Scottish Budget on 13 January 2026: 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% above £125,140.
• Rest-of-UK Income Tax — three bands, unchanged and frozen since 2021/22: basic 20% to £50,270, higher 40% to £125,140, additional 45% above.
• Personal Allowance — £12,570, tapered by £1 for every £2 of income over £100,000 and gone entirely at £125,140. This taper is reserved, so it works identically in both places.
• Dividend tax, corporation tax, National Insurance and Business Asset Disposal Relief are all reserved. Dividend allowance £500, dividend rates 10.75%/35.75%/39.35%, corporation tax 19% to £50,000 profit rising to an effective 26.5% in the marginal band and 25% above £250,000, Class 4 NIC 6%/2%, employer NIC 15% above a £5,000 secondary threshold, BADR at 18%. None of these differ by a single penny for a Scottish taxpayer.

That split — devolved income tax, reserved everything else — is the entire mechanism behind this article. The sole-trader route is taxed under the devolved bands. The company route's second layer, the dividend, is taxed under the reserved bands. Move a devolved-vs-reserved boundary and one side of the comparison shifts while the other stands still.

The comparison, run properly

Same illustrative associate as the England piece: an entirely private book, £120,000 of annual profit, all of it drawn, no NHS pension in play. Figures are 2026/27, rounded to the nearest pound.

As a sole trader, Scottish taxpayer. The Personal Allowance tapers to £2,570, the same as in England, leaving taxable income of £117,430. Taxed through the starter, basic, intermediate and higher bands in full, then the remainder at the 45% advanced rate — because at £120,000 the taxpayer has not yet reached the £125,140 gross income that would tip them into the 48% top rate — income tax comes to £44,232. Class 4 National Insurance is unaffected by residence and comes to the same £3,657 as in England. Total tax and NIC £47,889, take-home £72,111 — £4,800 less take-home than an identical English sole trader keeps on the same £120,000.

Through a company. Salary £12,570, employer NIC on the £7,570 above the secondary threshold £1,136, company profit £106,295 taxed in the marginal relief band at an effective 22.97% for corporation tax of £24,418, dividends of £81,876 taxed at £19,792 after the £500 allowance. Total tax £45,346, take-home £74,654 — identical to the English figure, because not one component of the company route is set in Scotland.

Put the two routes side by side and the sole trader's Scotland-only £4,800 disadvantage is enough to swing the whole comparison: the company goes from £2,257 behind in England to £2,543 ahead in Scotland.

Why the answer flips, mechanically

England's higher rate (40%) does not start until £50,271, and its jump to the 45% additional rate waits until £125,140 — a single big step covering most of the income range that matters here. Scotland reaches a 42% higher rate at £43,663, a full £6,608 sooner, and steps up again to a 45% advanced rate at £75,001, fifty thousand pounds before the equivalent rest-of-UK jump. A Scottish associate is therefore paying a marginal rate at or above the dividend higher rate of 35.75% across a much wider slice of their income than an English one — while the dividend rate itself, the thing the company route is being measured against, does not move at all. The gap is not a rounding difference; it compounds across every pound between £43,663 and £125,140.

Where this still does not help

The caveats in the England piece apply here without change, because none of them are income-tax questions. Retained profit, company pension contributions, a genuine exit and real income-sharing still work the same way regardless of residence. The one that dentistry specifically needs re-stated for Scotland is the NHS pension.

NHS dentists north of the border are members of the NHS Superannuation Scheme (Scotland), administered by the Scottish Public Pensions Agency rather than the NHS Business Services Authority — a different administrator, not a different deal. The 2015 scheme accrues at the same 1/54 of pensionable earnings, but the employer contribution is 22.5%, slightly below the 23.7% paid in England. On £70,000 of pensionable earnings that is still roughly £15,750 a year of employer-funded, index-linked pension handed to a Scottish associate for a 12.5% member contribution — not identical to the England figure, but nowhere near replaced by a tax saving on the private side. Practitioner pensionable earnings still have to be earned personally, so routing NHS work through a company still forfeits it, in Scotland exactly as in England.

Business Asset Disposal Relief is unaffected by any of this — it is a UK-wide capital gains relief, still 18% against a 35.75% dividend rate on full extraction, and still the strongest single argument for holding a company that has something to sell.

What to do this week

1. Confirm you are actually a Scottish taxpayer. It is a residence test on your main home, checked against the address HMRC holds for you — not a guess based on where you work. Update it if it is wrong; getting this backwards means every figure above applies to the wrong person.
2. Total your genuinely private, fully-drawn profit for the year separately from any NHS pensionable income, because only the former belongs in this comparison at all.
3. Run your own number rather than borrow ours. £120,000 is illustrative; the crossover between the two routes sits at a different profit level for everyone, and it sits lower in Scotland than in England because the devolved bands bite earlier. Use the incorporation calculator with your own figures.
4. If you already have a company and drew everything last year, re-test it now rather than at your accountant's year-end deadline — the Scottish Budget resets these bands every January, and a band move changes only one side of this comparison.

None of this replaces running your own figures with your own mix of NHS and private income — see our associate tax guide for the sole-trader side in full — but the headline is straightforward. If you are a Scottish taxpayer with a substantial, largely private, fully-drawn income, the conclusion our England article reached does not transfer north of the border, and it is worth asking us to run your specific numbers before assuming it does.
