What is a balance sheet?

A balance sheet is a snapshot of what a business owns, what it owes and what is left for the owners, at a single date. Assets always equal liabilities plus equity, which is why it balances.

How do you read a balance sheet?

The top half lists assets: fixed assets such as vehicles and equipment, then current assets such as stock, debtors and cash. The middle lists liabilities: what is owed to suppliers, HMRC, lenders and, in a company, the directors. Assets less liabilities is net assets.

The bottom half shows where those net assets came from: share capital the owners put in, plus retained profit the business has earned and kept. That total always equals net assets, because every pound of value in the business was either put in or earned.

Read it for three things. Can the business pay its short-term debts from its short-term assets? Is it carrying more debt than it should? And is net assets growing, which means the business is keeping some of what it earns.

How is a balance sheet different from a profit and loss?

A profit and loss covers a period: what came in and went out between two dates. A balance sheet is a single date: what the position was at midnight on 31 March. One is a film, the other a photograph.

They connect through retained profit. This year's profit, less anything paid out as dividends, is added to retained profit on the balance sheet. A business can show a healthy profit and a weak balance sheet if that profit has been drawn out faster than it was earned.

COMMON QUESTIONS

Questions people ask.

Do sole traders need a balance sheet?

Not for HMRC. The Self Assessment return asks for profit, not the balance sheet, and sole traders on the cash basis rarely produce one. It is still the only document that shows what the business is worth, and lenders and mortgage brokers often ask for it, so many prepare one anyway.

What does it mean if net assets are negative?

The business owes more than it has. For a company this is called being balance-sheet insolvent, and it obliges the directors to take care, because trading on while unable to pay creditors carries personal risk. It is common in a company's first year and worth fixing quickly after that.

Why does the bank figure on my balance sheet not match my bank?

Usually timing. The balance sheet shows the reconciled book balance, which includes payments made and receipts recorded that have not yet cleared. If the difference is not explained by uncleared items, something has been recorded twice or missed, and the bank reconciliation will find it.

Is a balance sheet public?

For a limited company, yes. The balance sheet is the one statement every company must file at Companies House, even under the smallest filing options, so anyone can look it up. Sole traders and partnerships file nothing and theirs stays private.
