Salary, dividends and expenses without the jargon fog
When contractors talk about “limited company take-home,” they usually mean what ends up available after Corporation Tax, income tax on salary, National Insurance where it applies, and dividend tax—not the invoice total.
Your company may charge a day rate to the client or agency. From that trading income the company meets allowable business costs, pays Corporation Tax on taxable profits, and only then can distribute what’s left under the rules for salary and dividends (and other lawful extractions).
Comparing a gross day rate with an umbrella net salary without modelling those steps will mislead you.
Many contractors pay themselves a director salary. A common planning reference is a salary around the personal allowance (for example £12,570 in the 2026/27 framework used on this site), so that allowance is used against salary before dividends are considered. That is a widespread pattern, not a legal requirement.
Salary is subject to income tax and National Insurance rules like other employment income, with company-side employer NI considerations depending on the level paid. Raising salary is not automatically “better” or “worse”—it changes the mix of taxes.
After Corporation Tax, remaining profit may be paid as dividends to shareholders. Dividend tax bands and the dividend allowance affect how much of that distribution you keep. Dividend tax rates differ from employment income rates, which is one reason limited company models can show a different take-home shape from PAYE for the same underlying contract value.
Dividends require available profit and proper company records. They are not a free top-up on top of an already emptied company.
Allowable business expenses reduce company profit and can therefore change Corporation Tax and what is left to extract. Only genuine, allowable costs belong in a serious model. Putting personal spending into the company because a calculator has an “expenses” box is how people get into trouble.
Accountancy fees are a normal professional cost of running a compliant company and are often included as a simple annual figure in planning tools.
Pension contributions—personal or via the company—change take-home and long-term savings differently. Student loan plans apply thresholds and rates that depend on your plan type. A useful calculator lets you toggle these so you see sensitivity, not so you avoid professional advice.
The free tool on this site models a simplified Outside IR35 limited company path: director salary, expenses, accountancy, Corporation Tax (including marginal relief where relevant in the model), dividends and related tax, with optional pension and student loan inputs. It sits next to an umbrella-style PAYE column so you can compare one assignment rate assumption under two operating models.
It will not match every accountant’s spreadsheet. It is designed to be transparent and adjustable so you can prepare better questions—not so you file a return from the screen alone.
