Home / Retained profit in a limited company
Retained profit is the post-corporation-tax company cash that has not been distributed as dividends or used for other purposes. It appears as a company asset on the balance sheet. For owner-managers, it is not money that has been lost — it is money that remains in the business, available for future use.
The standard sole trader mental model — earn money, pay tax, keep the rest — does not translate directly to a limited company. In a company, profit first pays corporation tax, and then the after-tax amount can either be distributed to shareholders or retained. What is retained is still real money, just held by the company rather than personally.
This creates planning flexibility that sole traders do not have. A sole trader pays income tax on all profit in the year it is earned, whether they spend it or not. A director can choose to extract less than the full post-tax profit and let the surplus accumulate in the company, effectively deferring personal income tax on the retained amount until it is eventually distributed.
The value of that deferral depends on current and future tax rates and personal circumstances. If the director expects to be in a lower rate band in future years — approaching retirement, reducing working hours, or planning a significant deductible expenditure — retaining now and extracting later may improve the overall position.
The retained company cash figure shown in this calculator is company profit after director salary, employer NI, company pension contributions, corporation tax and dividends chosen. If dividends are set lower than available distributable profit, the difference appears as retained cash.
This figure represents the available cash in the current period's modelling. It does not include accumulated reserves from previous periods, directors' loan balances, or any other balance sheet items not captured in the annual profit inputs.
To see the effect of retaining more, reduce the dividends figure and watch the retained cash increase alongside the reduction in dividend tax. The personal take-home falls, but the company balance grows.
Retained company cash can be extracted in several ways: as dividends in a future year when the director is in a lower band; as director salary in a future lower-income year; via a company pension contribution before extraction; or as part of a company sale, which may attract business asset disposal relief at a 10% rate on qualifying gains.
The choice between these routes depends significantly on future plans. A director planning to sell the business may treat retained profit differently from one planning to draw it as income over a long period. A director expecting a significant non-working year may plan to extract at basic rate dividend rates during that year.
None of these future strategies can be fully modelled in a single-year calculator. But understanding that retained profit exists as a planning variable — not a leftover — is the starting point for better decisions.
Not all retained profit is available for future personal distribution. Some is needed as working capital — the cash the company needs to meet its operating obligations, fund client projects or cover seasonal gaps. Treating all retained profit as future dividends in waiting can create cashflow problems.
Before deciding how much to retain, consider the company's realistic working capital requirement, any planned capital expenditure, and whether a pension contribution in the current period is more efficient than retaining and distributing later.
The pension route is often particularly effective in the marginal relief band (profits between £50,000 and £250,000). A company pension contribution saves 26.5% in corporation tax at the margin and removes the amount entirely from personal income rather than just deferring it.
The homepage calculator is the fastest way to turn this guidance into a concrete estimate for company tax, dividends and personal take-home.
No. Retained profit is a company asset that can be extracted later — as dividends, salary, company pension contributions or via a business sale. It is deferred income, not lost income.
The company pays corporation tax on profit in the year it is earned, regardless of whether it is distributed. Personal income tax and dividend tax only apply when the profit is extracted personally.
You can make a director's loan from the company, but loans must be repaid within nine months of the accounting year-end or a 25% tax charge (S455 tax) applies. Persistent unpaid director's loans attract additional scrutiny from HMRC.
Accumulated retained profits can increase the value of the company when sold. If the sale qualifies for Business Asset Disposal Relief, gains may be taxed at 10% rather than the standard capital gains rate. This is one reason why building retained profit can be more efficient than extracting it all as dividends.
