What Is an Accountant’s Role in Bookkeeping? UK Guide

An accountant uses bookkeeping records to prepare accounts, calculate tax, advise the business and test whether the reported figures are complete and reasonable. A bookkeeper normally records and reconciles day-to-day transactions; an accountant interprets those records and applies financial-reporting and tax rules.

The roles overlap, and many firms provide both. The important distinction is responsibility, competence and the scope agreed with the client.

Bookkeeper versus accountant

These are common patterns, not protected boundaries. A suitably trained bookkeeper may handle VAT or payroll, while an accountant may provide a fully outsourced bookkeeping service.

Setting up the bookkeeping system

An accountant can help choose the chart of accounts, accounting date, VAT settings and reporting structure. A good setup distinguishes:

• business and private transactions;
• capital assets and day-to-day expenses;
• different VAT rates and schemes;
• departments, locations or projects;
• director or owner accounts;
• loans, interest and repayments; and
• amounts due to HMRC and pension providers.

Correct design reduces year-end rework and produces more useful reports.

Reviewing bookkeeping quality

An accountant does not merely accept a software profit figure. Review procedures can include:

• reconciling bank, card and loan statements;
• reviewing unusual, duplicate or uncategorised entries;
• checking customer and supplier balances;
• reconciling VAT and payroll control accounts;
• testing director’s loan or proprietor transactions;
• reviewing fixed assets and depreciation;
• checking stock and work in progress; and
• comparing margins and expenses with prior periods.

Year-end adjustments

Bookkeeping captures transactions, but accounts may require adjustments for:

• accruals and prepayments;
• deferred or accrued income;
• depreciation and asset disposals;
• stock and work in progress;
• bad debts and provisions;
• foreign-currency balances;
• tax liabilities; and
• events occurring after the reporting date.

Tax compliance

Accurate records support VAT Returns, payroll submissions, Corporation Tax returns, partnership returns and Self Assessment. The accountant identifies tax adjustments rather than assuming every accounting expense is deductible.

They may also check registration thresholds, deadlines, claims and elections. The taxpayer or company directors remain legally responsible for accurate returns even when an agent prepares them.

Making Tax Digital

For qualifying sole traders and landlords, MTD for Income Tax requires compatible software, digital records and quarterly updates. An accountant can:

• check the mandatory start date;
• select or connect software;
• create digital workflows;
• act as the authorised agent;
• review quarterly data; and
• make year-end adjustments and submit the final return.

See our 2026/27 MTD requirements.

Management information

Current bookkeeping allows the accountant to produce:

• monthly profit and loss reports;
• cash-flow forecasts;
• aged debtor and creditor reports;
• gross-margin analysis;
• budgets and variance reports;
• break-even calculations; and
• tax and dividend forecasts.

These reports are only as reliable as the underlying records and reconciliations.

Internal controls and fraud prevention

An accountant can recommend approval limits, separation of duties, bank controls, supplier verification and restricted software access. In a small business where duties cannot be fully separated, owner review and exception reporting become more important.

The external accountant is not automatically responsible for detecting every fraud unless the engagement specifically includes audit or investigation work.

What information should be supplied?

• bank, card, loan and finance statements;
• sales and purchase invoices;
• payroll and pension reports;
• VAT submissions and HMRC correspondence;
• contracts and asset purchases;
• stock counts;
• details of personal or director transactions;
• prior accounts and tax returns; and
• explanations for unusual transactions.

Provide information regularly through a secure portal rather than waiting until the filing deadline.

How often should an accountant review records?

The frequency depends on transaction volume, complexity and reporting needs. Monthly review is often appropriate for VAT-registered or growing businesses. Quarterly review may suit a smaller stable business, while annual-only work provides limited scope for timely corrections or planning.

Choosing an accountant

Consider qualifications, relevant industry experience, tax and software knowledge, professional indemnity insurance, data-security arrangements, pricing and service levels. Confirm whether bookkeeping, payroll, VAT, accounts and tax filings are included.

Ask who will perform the work and what the business must complete before each deadline.

Frequently asked questions

Does an accountant replace a bookkeeper?

Not necessarily. A bookkeeper can maintain daily records while the accountant reviews them and handles accounts, tax and advice.

Can accounting software replace an accountant?

Software records and processes data but does not automatically resolve judgement, tax treatment, legal responsibility or commercial decisions.

Who is responsible for errors?

The engagement terms determine professional responsibilities, but taxpayers and directors remain responsible to HMRC and Companies House for their legal obligations.

Official source

HMRC confirms in its record-keeping guidance that businesses must maintain accurate records capable of identifying business transactions.
