Every UK limited company must prepare annual accounts at the end of its financial year and file them at Companies House. The accounts give a snapshot of the company’s financial position and performance. The notes to the accounts explain the numbers in more detail and disclose information that the law requires.

This guide covers what goes into the accounts, what the notes must include and how the filing requirements differ depending on your company’s size.

What annual accounts include

A full set of annual accounts for a UK company contains:

  • Balance sheet (statement of financial position)
  • Profit and loss account (income statement)
  • Notes to the accounts
  • Directors’ report (not required for small companies taking the exemption)
  • Auditor’s report (only if an audit is required)

The balance sheet must be signed by a director and dated. It is the primary document that gets filed at Companies House for small companies.

The balance sheet

The balance sheet shows what the company owns (assets), what it owes (liabilities) and the residual equity belonging to shareholders, all at a single point in time – your financial year end.

Structure

SectionWhat it includes
Fixed assetsTangible assets (equipment, vehicles), intangible assets (goodwill, patents), investments
Current assetsStock, debtors (trade receivables), cash at bank and in hand
Creditors: amounts falling due within one yearTrade creditors, tax owed, short-term loans, accruals
Net current assetsCurrent assets minus current creditors
Total assets less current liabilitiesFixed assets plus net current assets
Creditors: amounts falling due after more than one yearLong-term loans, deferred tax
Net assetsTotal assets less all liabilities
Capital and reservesShare capital, share premium, retained earnings (profit and loss account reserve)

The bottom line is straightforward: net assets must equal capital and reserves. If they do not balance, something is wrong.

Comparative figures

The balance sheet must show figures for both the current year and the previous year side by side. This lets anyone reading the accounts see how the company’s position has changed.

The profit and loss account

The profit and loss account (P&L) shows income, expenses and the resulting profit or loss for the accounting period.

LineWhat it covers
TurnoverRevenue from your main trading activities
Cost of salesDirect costs of producing goods or delivering services
Gross profitTurnover minus cost of sales
Administrative expensesOverheads – rent, salaries, office costs, professional fees
Operating profitGross profit minus administrative expenses
Interest payable/receivableBorrowing costs and bank interest earned
Profit before taxOperating profit adjusted for interest
TaxCorporation Tax charge for the period
Profit after taxThe bottom line – what remains after tax

Small companies that file abridged accounts at Companies House do not need to file the P&L publicly. It is still prepared internally and used for the Company Tax Return , but it stays private.

Notes to the accounts

The notes are where the real detail lives. They explain the accounting policies used, break down the summary figures in the balance sheet and P&L, and provide disclosures required by law and accounting standards.

Accounting policies note

Every set of accounts starts with a note describing the basis of preparation and the key accounting policies. This typically covers:

  • Which accounting standard is used (FRS 102 Section 1A, FRS 105 or full FRS 102)
  • Whether the company is a going concern
  • Revenue recognition – when turnover is recognised
  • Depreciation rates and methods for fixed assets
  • Stock valuation method (cost, net realisable value)
  • Foreign currency translation policy (if applicable)

Common required notes

NoteWhat it discloses
Fixed assetsCost, accumulated depreciation and net book value for each category, with movements during the year
DebtorsBreakdown of trade debtors, prepayments and other debtors
CreditorsBreakdown of trade creditors, tax and social security, accruals, other creditors
Share capitalNumber and class of shares, changes during the year
Loans and borrowingsTerms, interest rates, repayment schedule
Directors’ remunerationTotal pay and benefits (not required for micro-entities using FRS 105)
Related party transactionsTransactions with directors, shareholders, connected companies
Commitments and contingenciesOperating leases, guarantees, pending legal claims
Post balance sheet eventsSignificant events between the year end and the date the accounts are signed

Director’s loan account

If a director owes money to the company at year end (an overdrawn director’s loan account), this must be disclosed. It also triggers a potential Section 455 tax charge at 33.75% of the outstanding balance, payable 9 months after the year end. The tax is refundable when the loan is repaid, but the cash flow impact catches many directors off guard.

Accounting standards and company size

The level of detail in your accounts depends on which accounting standard you use, which in turn depends on your company’s size.

CategoryTurnoverBalance sheet totalEmployeesStandard
Micro-entityUp to £632,000Up to £316,000Up to 10FRS 105
Small companyUp to £10.2 millionUp to £5.1 millionUp to 50FRS 102 Section 1A
Medium companyUp to £36 millionUp to £18 millionUp to 250FRS 102 (with reduced disclosures)
Large companyAbove medium thresholdsAbove medium thresholdsOver 250Full FRS 102 or IFRS

You must meet at least two of the three criteria (turnover, balance sheet, employees) to qualify for a category. The test is applied over two consecutive years – you move up or down only if you cross the threshold for two years running.

Micro-entity accounts (FRS 105)

Micro-entities file the simplest accounts at Companies House:

  • Balance sheet only (no P&L, no directors’ report)
  • Very limited notes (accounting policies and guarantees only)
  • No requirement to disclose director remuneration or related party transactions

The trade-off is that FRS 105 does not allow revaluation of assets, recognition of deferred tax, or capitalisation of development costs.

Small company accounts (FRS 102 Section 1A)

Small companies can file abridged accounts:

  • Balance sheet (can combine certain line items)
  • Notes to the accounts (reduced disclosures compared to full FRS 102)
  • No P&L needs to be filed publicly
  • No directors’ report required (though one must still be prepared)

Most UK companies qualify as small, so this is the most common filing format.

Filing at Companies House

Deadlines

  • Private companies – 9 months from the accounting reference date
  • Public companies – 6 months from the accounting reference date

Late filing attracts automatic penalties starting at £150 for private companies.

Filing format

Companies House accepts accounts filed:

  • Online through the Companies House WebFiling service
  • Via software filing using compatible accounting software
  • On paper (but this is slower and more error-prone)

For the Corporation Tax return, accounts must be submitted to HMRC in iXBRL (inline eXtensible Business Reporting Language) format. Most accounting software handles this conversion automatically.

Preparing the accounts – practical steps

Step 1: Close the books

Complete all bank reconciliations, enter outstanding invoices, calculate accruals and prepayments. Your trial balance at this point should reflect every transaction in the accounting period. See our guide on the UK year-end process for a detailed walkthrough.

Step 2: Make year-end adjustments

AdjustmentPurpose
DepreciationSpread the cost of fixed assets over their useful life
AccrualsRecognise expenses incurred but not yet invoiced
PrepaymentsDefer expenses paid in advance to the correct period
Bad debt provisionWrite down debtors you do not expect to collect
Stock adjustmentAdjust stock to the lower of cost or net realisable value
Corporation Tax provisionEstimate the tax charge for the year

Step 3: Produce the accounts

Generate the balance sheet, P&L and notes from your adjusted trial balance. Check that the balance sheet balances, the P&L ties to the movement in retained earnings, and all required notes are complete.

If retained earnings does not tie back to the current year result, review closing profit and loss accounts at year end before treating the difference as suspense or rounding.

Step 4: Director approval

At least one director must sign the balance sheet to confirm the accounts give a true and fair view (or, for micro-entities, are prepared in accordance with FRS 105). The accounts must be approved by the board before filing.

Step 5: File

Submit the accounts to Companies House within the deadline. If your company requires an audit, the auditor’s report must be attached. If an audit is not required, the accounts should include the small company or micro-entity audit exemption statement.

Audit requirements

Most small companies are exempt from audit. You qualify for the exemption if you meet at least two of:

  • Turnover of no more than £10.2 million
  • Balance sheet total of no more than £5.1 million
  • No more than 50 employees

Even if your company is exempt, shareholders holding at least 10% of shares can require an audit by giving notice to the company.

Common mistakes

Not matching accruals to the right period

If you receive an invoice in April for work done in March, the cost belongs in March’s accounts. Missing accruals understate expenses and overstate profit, which means you may overpay tax in the short term and have to correct it later.

Forgetting post balance sheet events

Events after the year end but before the accounts are signed may need to be disclosed or even adjusted for. A major customer going into administration the week after your year end, for example, may require you to write down the debtor in the year-end accounts.

Filing the wrong format

Filing full accounts when you could file abridged, or failing to include required notes, leads to rejection or unnecessary disclosure of sensitive information. Check which format your company qualifies for before filing.

Transactions between the company and its directors, shareholders or connected companies must be disclosed. This includes the director’s loan account, rent paid to a director’s property company, and management charges between group companies. Missing these disclosures can trigger questions from HMRC and Companies House.
