IR35 and Scottish Tax: How Contractor Take-Home Differs in Scotland

A Scottish contractor caught by IR35 receives a deemed salary taxed at Scottish income tax rates. Because Scotland's higher rate of 42% starts at £43,662 — compared with 40% at £50,270 in England — a Scottish IR35 contractor earning a day rate that translates to £50,000–£75,000 typically takes home less than an identical contractor based in England.

How IR35 works for Scottish contractors

IR35 (the off-payroll working rules) treats the income from an engagement as deemed employment income if the hypothetical employment test is met. The end client or fee payer deducts PAYE and National Insurance before the contractor's personal service company receives the net amount. The contractor then pays Scottish income tax on that deemed salary at the rates applicable to their residence.

The Scottish tax disadvantage in numbers

A Scottish contractor receiving a deemed salary of £60,000 pays: 19% on income from £12,571–£14,876, 20% from £14,877–£26,561, 21% from £26,562–£43,662, and 42% from £43,663–£60,000. In England the same contractor would pay 20% from £12,571–£50,270 and 40% from £50,271–£60,000. The Scottish contractor pays roughly £1,500–£2,000 more tax on this income.

Operating outside IR35 in Scotland

A Scottish contractor operating outside IR35 through a limited company retains the ability to take a combination of salary and dividends. Dividends are taxed at UK-wide dividend rates rather than Scottish income tax rates, which can partially offset the Scottish income tax disadvantage on salary. The salary component is still subject to Scottish rates, so the optimal split needs careful modelling each year.

What Scottish contractors should consider

• Model take-home for both inside and outside IR35 scenarios using Scottish rates.

• If inside IR35, consider whether the day rate compensates for the higher tax cost.

• If outside IR35, ensure the contract and working practices genuinely support that status.

• Review salary and dividend split annually given the impact of Scottish higher rates.

The intermediaries legislation and Scottish residence

Your residency for Scottish tax purposes is determined by where you live — not where the client is located. A Scottish-resident contractor working remotely for a London client is still a Scottish taxpayer and Scottish rates apply to the deemed salary. This is a common point of confusion in the contractor market.
