A chartered accountant prepares your accounts and tax returns, but for a small business their role usually goes much further. They keep you compliant with HMRC and Companies House, help you plan for tax, manage cash flow and use your figures to make better decisions.

For local firms, working with an accountant in Milton Keynes means support that is easy to reach and grounded in how businesses in the area operate. This guide explains what a chartered accountant does, when it makes sense to hire one and how to choose the right firm.

What Is a Chartered Accountant?

A chartered accountant is a member of a professional accountancy body with a Royal Charter, such as the ICAEW, ICAS or ACCA. Becoming chartered involves several years of professional exams and supervised work experience, followed by ongoing training and a professional code of ethics.

This matters because “accountant” is not a protected title in the UK, so anyone can use it, whatever their training. A chartered accountant is qualified, regulated by their professional body and, when offering services to the public, generally required to hold professional indemnity insurance.

For a small business, that means advice from someone with tested knowledge of UK tax, financial reporting and company law, and a professional body to turn to if something goes wrong.

What Does a Chartered Accountant Do for a Small Business?

Preparing Business Accounts

Every limited company must prepare annual accounts and file them with Companies House, usually within nine months of its financial year end. These year-end accounts include a profit and loss account, showing income, costs and profit, and a balance sheet, showing what the business owns and owes.

Sole traders and partnerships do not file public accounts, but they still need accurate figures for their tax returns. An accountant prepares these financial statements correctly and in the required format.

Managing Tax and HMRC Compliance

• Corporation Tax: preparing the company tax return and calculating the tax due, which most small companies pay nine months and one day after their year end.
• Self Assessment: tax returns for sole traders, partners and company directors with income outside PAYE, such as dividends.
• VAT: registration, returns through Making Tax Digital (MTD) compatible software and advice on the right VAT scheme.
• PAYE: making sure payroll taxes are calculated and reported correctly.

Missing an HMRC deadline usually means an automatic penalty, so having someone track every date is one of the most practical benefits of professional support.

Bookkeeping and Financial Record Keeping

Bookkeeping is the day-to-day recording of sales, purchases, receipts and payments. Tax returns, VAT and management information are only as reliable as the financial records behind them.

Many accountants set clients up on cloud accounting software such as Xero or QuickBooks, then either handle the bookkeeping or review it regularly to catch errors early. Limited companies must generally keep records for at least six years.

Cash Flow Management

A profitable business can still run short of cash, for example when customers pay late or a large tax bill falls due. An accountant can prepare cash flow forecasts, flag pressure points in advance and suggest practical steps, such as tightening payment terms, chasing debtors sooner or setting money aside for VAT and Corporation Tax.

Tax Planning and Tax Efficiency

Tax planning means using the reliefs and allowances the law provides, legitimately and transparently. For a small business, that might include claiming all allowable business expenses, using capital allowances on equipment, choosing the right business structure or, for directors, agreeing a sensible mix of salary and dividends.

The right approach depends on your circumstances. A chartered accountant will also steer you away from aggressive schemes that HMRC is likely to challenge.

Payroll and PAYE

Employers must report pay and deductions to HMRC on or before each payday and meet their workplace pension duties. An accountant can run payroll, produce payslips, handle starters and leavers and issue year-end forms such as P60s. Construction businesses may also need help with the Construction Industry Scheme (CIS).

Financial Forecasting and Business Planning

Budgets and forecasts turn your plans into numbers. Monthly or quarterly management accounts compare actual results with your budget, so you can spot problems early. Your accountant can also prepare forecasts to support a loan or investment application.

Business Growth and Strategic Advice

As a business grows, decisions get bigger: hiring staff, taking on premises, buying equipment, raising finance or moving from sole trader to limited company. An accountant can model the financial impact of each option, show which products or customers are most profitable and help you plan for long-term growth.

Why Should a Small Business Hire a Chartered Accountant?

• More time: hours spent on bookkeeping and tax returns go back into running the business.
• Fewer errors: professional preparation reduces costly mistakes and penalties.
• Confidence with HMRC: deadlines, filings and correspondence are handled correctly.
• Early warnings: financial risks and cash flow pressures are spotted before they become serious.
• Better decisions: clear, up-to-date figures support pricing, hiring and investment choices.

When Should a Small Business Hire an Accountant?

There is no single right moment, but professional support becomes particularly valuable when you are:

• starting a business and choosing between sole trader, partnership or limited company
• forming a limited company, which brings Companies House and Corporation Tax duties
• growing towards the VAT registration threshold, currently £90,000 of taxable turnover in any rolling 12 months
• taking on your first employee
• facing more complex tax affairs, such as Making Tax Digital for Income Tax, which began in April 2026 for sole traders and landlords with qualifying income over £50,000
• experiencing cash flow problems
• planning expansion, investment or a sale

How Much Does a Chartered Accountant Cost?

There is no standard price for accounting services. Fees depend on your business structure, turnover, the number of transactions, the services you need, payroll and VAT requirements and how complex your accounts are.

Many firms offer fixed monthly fees for an agreed package. Ask for a written quote that lists exactly what is included, so you can compare like for like. The cheapest quote is not always the best value if it leaves out services you need.

Chartered Accountant vs DIY Accounting

Accounting software has made bookkeeping easier, and some small businesses manage well on their own. The question is when the time saved and the advice gained outweigh the cost.

Software records your figures, but it will not tell you whether you are claiming everything you should, whether your structure still suits you or how to prepare for a large tax bill.
