What Is a Profit and Loss Account for a Limited Company?

A profit and loss account (P&L) is a financial statement that shows how much a limited company has earned, what it has spent and whether it made a profit or loss over a specific period. It summarises the company’s financial performance by comparing income with expenses, usually across a financial year.

For UK limited companies, the profit and loss account is an important part of the annual accounts prepared for shareholders and used to support Corporation Tax reporting. It also helps directors understand whether the business model is working, which costs are rising and how much money the company is generating from its activities.

However, making a profit on paper does not necessarily mean a company has enough cash in its bank account. Understanding that distinction is essential for founders, directors and business owners. This guide explains what a profit and loss account contains, how to read one, how it differs from a balance sheet, and what UK limited companies need to know about preparing and filing it.

What Does a Profit and Loss Account Show?

A profit and loss account records a company’s income and expenses over a defined accounting period. It calculates the difference between the revenue the company generates and the costs it incurs. If income exceeds expenses, the company generally reports a profit. If expenses exceed income, it reports a loss.

For example, suppose a small UK consultancy earns £120,000 in revenue during its financial year. It spends £45,000 on staff, £12,000 on software and office costs, £8,000 on marketing and £15,000 on other operating expenses. Its profit before tax would be:

• Revenue: £120,000
• Total expenses: £80,000
• Profit before tax: £40,000

The P&L helps the directors see how the business performed during that year, rather than simply how much money it held at the year-end. You may also hear this statement called an income statement or a statement of profit or loss. These terms broadly refer to the same type of financial report, although the presentation and terminology can vary depending on the accounting framework used.

What Information Is Included in a Profit and Loss Account?

The precise format depends on the company’s size, accounting framework and reporting requirements. A typical profit and loss account may include the following items.

1. Turnover or revenue

Turnover is the income a company earns from its ordinary business activities, such as selling products, providing services or charging subscription fees. For example, a software company that charges customers £2,000 a month for its platform records revenue from those subscriptions as it earns it under the applicable accounting rules. Turnover is not the same as cash received. A company may have issued an invoice and recognised revenue even though the customer has not paid yet.

2. Cost of sales

Cost of sales includes costs directly associated with producing goods or delivering services. For a retailer, this might include the purchase cost of products sold. For a manufacturer, it could include raw materials and direct production labour. A service business may have a different cost structure, with direct delivery costs depending on the nature of its work. Subtracting cost of sales from turnover gives gross profit.

3. Operating expenses

Operating expenses are the costs of running the business that are not included in cost of sales. Common examples include:

• Salaries and employer National Insurance contributions
• Rent and utilities
• Marketing and advertising
• Software subscriptions
• Insurance and professional fees
• Travel and administrative expenses
• Depreciation on eligible fixed assets

These costs reduce the profit generated by the company. Reviewing them regularly helps directors identify unnecessary spending and assess whether growth is improving or weakening profitability.

4. Gross profit and operating profit

Gross profit is revenue less cost of sales. It indicates how much remains from sales after accounting for the direct costs of delivering the goods or services. Operating profit goes further by deducting operating expenses and accounting for relevant operating items. A company can have strong revenue but weak operating profit if its delivery costs, payroll or overheads are too high.

5. Interest and other financial costs

A P&L may show interest payable on business loans, overdrafts or other financing arrangements. It may also include relevant interest income or other financial items. These figures help directors assess the cost of borrowing and how much of the company’s operating earnings remains after financing costs.

6. Profit before tax and tax expense

Profit before tax is the profit remaining after the relevant income, expenses and financial items have been accounted for, but before the income tax expense shown in the accounts. The accounts may then show a tax charge, including Corporation Tax where applicable, to arrive at profit or loss for the financial year.

Accounting profit and taxable profit are not always the same. Tax adjustments may be needed for items treated differently under tax rules, such as certain disallowable expenses or capital allowances. The amount of Corporation Tax due should therefore not be calculated by simply applying a tax rate to the P&L’s final profit figure.

7. Profit or loss for the year

This is the final result after the relevant expenses and tax charge have been accounted for. A positive figure means the company made a profit for the period. A negative figure means it made a loss. That result may contribute to the company’s accumulated reserves, but it does not automatically determine how much cash is available for spending or whether a dividend can lawfully be paid.

Example of a Limited Company Profit and Loss Account

Consider a fictional UK limited company that provides digital marketing services. Its simplified annual P&L might look like this:

This is an illustrative example, not a statutory accounts template. The tax expense is hypothetical and does not represent a calculation of the company’s actual Corporation Tax liability. The company generated £180,000 in turnover but retained £49,600 as profit after the costs and illustrative tax charge shown.

Directors could use these figures to assess gross margin, monitor staffing costs, evaluate borrowing and plan future investment. They would still need to examine the balance sheet and cash-flow position to understand the company’s wider financial health.

Why Is a Profit and Loss Account Important?

A P&L is more than a document prepared for an accountant. Used properly, it helps business owners make better commercial decisions.

Measuring profitability

Turnover alone does not tell you whether a business is successful. A company generating £500,000 in annual sales may be less profitable than one generating £250,000 if its costs are disproportionately high. The P&L shows how much revenue remains after different categories of expense.

Controlling costs

Comparing results across months, quarters or financial years can reveal changes that might otherwise go unnoticed. For example, if revenue remains stable while subcontractor costs rise significantly, directors can investigate pricing, productivity or supplier arrangements before the problem becomes more serious.

Supporting business planning

Founders can use historical P&L figures to build budgets, forecast future performance and decide whether the company can afford to hire staff, increase marketing expenditure or launch a new service. Comparisons are most useful when the figures are consistent and unusual one-off costs are clearly understood.

Supporting lenders and investors

Banks, investors and potential business partners may review profit and loss information when assessing a company’s performance and financial prospects. A P&L is not the only evidence they need, but it can help demonstrate revenue trends, cost control and the ability to generate earnings.

Supporting tax and accounting obligations

The P&L forms part of the company’s accounting records and helps inform its Corporation Tax computation. It is also generally part of the statutory accounts prepared for the company’s members, subject to the relevant accounting and reporting requirements.

What Is the Difference Between a Profit and Loss Account and a Balance Sheet?

The two statements serve different purposes.

A company might report a profit but have little cash available because customers have not paid their invoices, it has repaid loans or it has invested in equipment. Conversely, a company may have a healthy bank balance because it borrowed money, even though its trading activities are losing money. That is why directors should not assess performance using the P&L alone. The balance sheet and cash-flow information provide important additional context.

What Is the Difference Between Profit and Cash Flow?

Profit is calculated using accounting rules, which can recognise income and expenses at different times from when money enters or leaves the bank account. Cash flow tracks actual cash movements. Suppose a company completes £20,000 of work in March and correctly recognises the revenue in that period, but the customer pays in May. The March P&L may include the revenue even though the money has not yet arrived.

The opposite can also occur: a company receives a customer deposit before it has earned the revenue under the relevant accounting rules. This distinction matters because a profitable business can still struggle to pay salaries, suppliers or tax bills if cash receipts arrive too late. Directors should monitor payment terms, outstanding invoices, upcoming liabilities and cash forecasts alongside reported profit.

Do UK Limited Companies Have to Prepare a Profit and Loss Account?

Generally, yes. Directors of UK companies must prepare annual accounts for each financial year, and these accounts normally include a profit and loss account, a balance sheet and notes, with other reports required where applicable. The precise filing obligations depend on the company’s circumstances.

Companies House filing

Under the current rules, eligible small companies and micro-entities can generally omit the profit and loss account from the copy of their accounts filed at Companies House. This does not mean they can ignore the P&L altogether. They still need to prepare appropriate accounts for their members and meet relevant tax-reporting obligations. The accounts supplied to Companies House may be less detailed than the full accounts prepared for internal or statutory purposes.

From 1 April 2028, Companies House plans to require small companies and micro-entities to deliver a profit and loss account, with an option to opt out of publishing that information on the public register. The government has also announced a move to software-only accounts filing. Companies should follow updated official guidance as the implementation details develop.

HMRC and Corporation Tax

A company’s accounting profit helps form the starting point for calculating taxable profits, but adjustments may be required. Companies generally submit a Company Tax Return to HMRC with the accounts and tax computations required for their circumstances. Companies House filing and HMRC tax filing are separate obligations, with different requirements and deadlines. Filing one does not automatically satisfy the other.

Dormant companies

A company that qualifies as dormant for accounting purposes may have simpler reporting requirements and generally does not need to file a P&L at Companies House. However, dormancy depends on the company’s transactions and circumstances; it is not enough simply to have no sales. If a company has incurred transactions such as bank charges, it should check whether it still qualifies as dormant rather than assuming that it does.

How Should Directors Read a Profit and Loss Account?

Directors can get more value from a P&L by looking beyond the final profit figure.

1. Compare revenue over time. Check whether sales are growing, declining or fluctuating seasonally.
2. Review gross margin. A falling gross margin may indicate higher delivery costs, supplier price increases or pressure to reduce prices.
3. Track overheads. Identify costs growing faster than revenue and investigate whether the increase is justified.
4. Compare actual results with the budget. Variances can highlight missed sales targets, unexpected expenses or opportunities to improve performance.
5. Check profit against cash. Review the balance sheet, unpaid invoices, liabilities and cash-flow forecast before making major commitments.
6. Understand unusual items. One-off legal fees, exceptional repairs or non-recurring income can make a year look better or worse than the company’s normal trading performance.

For a startup, monthly management accounts can be especially useful. Annual accounts may meet formal reporting needs, but they can reveal problems too late for directors to respond quickly.

Common Mistakes to Avoid

• Treating turnover as profit: sales figures do not show what remains after costs.
• Assuming profit means cash is available: unpaid invoices and loan repayments can affect liquidity.
• Confusing accounting profit with taxable profit: tax adjustments may change the amount subject to Corporation Tax.
• Ignoring year-on-year trends: a single year’s result may conceal deteriorating margins or rising overheads.
• Using the P&L to decide dividends on its own: dividend payments must comply with company law and be supported by sufficient distributable profits, assessed using the relevant accounts and circumstances.
• Assuming a simplified Companies House filing removes other duties: preparing accounts for members and meeting HMRC obligations remain important.

For founders operating across borders, it is also worth ensuring that UK records are complete and that transactions involving foreign currencies, overseas suppliers or related companies are recorded consistently.

Frequently Asked Questions

1. Is a profit and loss account compulsory for a UK limited company?

Generally, yes. Directors must prepare annual accounts, which normally include a P&L. Some eligible companies can omit it from the version filed publicly at Companies House under current rules, but they still have other accounting and tax obligations.

2. How often should a company prepare a profit and loss account?

A company prepares annual accounts for its financial year, but directors may benefit from reviewing management P&Ls monthly or quarterly. Regular reporting makes it easier to spot problems and compare performance against budgets.

3. Is a profit and loss account the same as an income statement?

Broadly, yes. “Income statement” is a widely used alternative term for a report showing income, expenses and profit or loss over a period.

4. Can a company make a profit but have no cash?

Yes. For example, customers may owe the company money, or cash may have been used to repay borrowing or purchase assets. Profit and cash flow measure different things.

5. Does a P&L show how much Corporation Tax a company must pay?

Not by itself. The accounting profit may need to be adjusted under tax rules to calculate taxable profits. The company’s actual Corporation Tax liability depends on its circumstances and applicable tax rules.

6. Do small companies have to publish their profit and loss accounts?

Under current rules, eligible small companies and micro-entities can generally omit their P&L from the accounts filed at Companies House. From 1 April 2028, they are expected to submit it, with an option to opt out of public disclosure under the announced reforms.

7. Does a dormant company need a profit and loss account?

A company that qualifies as dormant can generally file dormant accounts without a P&L at Companies House. Directors should check the applicable rules and the company’s actual transactions before relying on dormant status.

8. Who can prepare a profit and loss account?

A director or business owner can prepare one if they have the necessary records and accounting knowledge. However, professional accounting support can help ensure that the figures follow the applicable accounting framework and that statutory and tax obligations are met.

Conclusion

A profit and loss account shows how a limited company has performed financially over a particular period. By setting out revenue, costs and the resulting profit or loss, it helps directors understand profitability, manage expenditure, plan growth and support tax reporting. But the final profit figure is only one part of the picture. Business owners should also review the balance sheet, cash flow and outstanding liabilities before making decisions about investment, hiring or dividends.
