Scottish bands apply to your sole-trader income. Dividends are taxed at UK-wide rates, so the company side is the same across the UK.

Most single-director companies with no other employees can't claim this - leave off if unsure. It only affects employer NI on your salary.

Tax comparison only, for 2026/27, assuming all profit is extracted in the year. A company typically adds £1,500–£2,500 a year in accountancy and filing costs on top.

The verdict on profit

keeping more per year ( vs )

Both routes keep almost exactly the same after tax.

Crossover point

Tax estimate only - it excludes accountancy costs, pensions and retained profit. Take advice before incorporating.

Take-home by profit level - where the lines cross

Sole trader Limited company

Company route: salary is a deductible expense, the company pays employer NI at above , Corporation Tax uses the small-profits rate, main rate and marginal relief, and the remaining profit is paid out as dividends taxed after the allowance. Sole trader route: Income Tax on profits plus Class 4 NI at then .

Tax isn't the whole story

A company still wins when you…

  • Don't need all the profit - retained profit is taxed only at Corporation Tax
  • Pay into a pension - employer contributions are deductible with no NI
  • Want limited liability for your personal assets
  • Need the credibility some clients and lenders prefer

But budget for the extras

  • Typically £1,500–£2,500 a year in accountancy and filing
  • Accounts, Companies House filings and payroll admin
  • Dividend paperwork and a director's Self Assessment
  • Possible tax on transferring an existing business in
