Sole Trader vs Limited Company Calculator

Would you keep more by incorporating? Both routes, side by side.

Every growing UK sole trader eventually asks the same question: would I actually keep more money by switching to a limited company and paying myself a salary plus dividends? The honest answer depends on your specific profit level, not a rule of thumb. This workbook runs the real 2026/27 Income Tax, National Insurance, Corporation Tax and dividend tax rules side by side on your own numbers, so you can see the actual take-home difference — not a guess.
