What to Ask Before Hiring an Accountant: The Ultimate Checklist for UK Business Owners in 2026
Hiring an accountant is not simply about finding the lowest monthly fee. The right accountant can help your limited company stay compliant, improve cash flow, plan for tax and make better growth decisions. The wrong choice can leave you paying for services you do not need: or discovering too late that important work was never included.
For UK limited companies and growing SMEs, accounting packages in 2026 can start from £85pm+, depending on your turnover, transaction volume, VAT position, payroll requirements and the level of advice you need.
This checklist explains what to ask before signing an engagement letter, how to compare accountant services and how to find an accountant for small business UK owners can rely on.
1. Do they specialise in limited companies and growing SMEs?
Start with the accountant’s experience. A firm that mainly works with large corporations may not understand the practical needs of an owner-managed company. Equally, an accountant who focuses only on basic personal tax may not provide the company tax and growth support you need.
Ask:
- How many limited companies do you currently advise?
- What size are your typical SME clients?
- Do you work with businesses in my sector?
- Have you supported companies through rapid growth?
- Can you help if we become VAT-registered, employ staff or open additional locations?
Sector knowledge can be valuable. An e-commerce business, construction company and consultancy may all need different support with VAT, expenses, payroll, cash flow and reporting.
You should also ask who will manage your account. Will you have a named accountant, or will every query go through a general helpdesk? A clear point of contact often makes a significant difference when you need a quick answer.
If you are ready to speak to potential firms, find an accountant through Accountant Search and provide details about your business so suitable professionals can contact you.
2. Which services are included in the monthly fee?
Never compare quotes based on price alone. Compare the work included in each proposal.
For a limited company, ask whether the quoted package includes:
- Annual statutory accounts
- Filing accounts with Companies House
- Corporation Tax calculations and the CT600 return
- Director payroll, where required
- Directors’ Self Assessment tax returns
- VAT registration and VAT returns
- Bookkeeping and bank reconciliations
- Payroll and pension administration
- Confirmation statement support
- Management accounts
- Cash-flow forecasting
- Year-round tax and business advice
Some firms advertise a low monthly price that covers only year-end accounts and Corporation Tax. Other services may be charged separately.
Ask directly: “What is not included in this price?”
Common additional charges may include:
- Extra directors’ tax returns
- VAT returns
- Payroll processing
- HMRC correspondence
- Companies House changes
- Dividend paperwork
- R&D tax relief claims
- Tax investigations
- Business forecasts and funding applications
- Bespoke tax planning
- Historical bookkeeping or correcting previous errors
A written schedule of inclusions and exclusions will help you make a fair comparison.
3. How much should accounting cost in 2026?
Your accountant should be able to explain how the fee has been calculated. In 2026, a straightforward limited company may find packages starting from around £85pm+, while a growing SME requiring bookkeeping, VAT, payroll and regular management information will usually pay more.
As a broad guide:
| Business needs | Indicative monthly cost |
|---|---|
| Simple limited company compliance | From £85pm+ |
| Accounts, Corporation Tax and director support | Around £100–£250 |
| VAT-registered company with basic payroll | Around £150–£300 |
| Growing SME with bookkeeping and management reports | Around £250–£500+ |
These are general planning figures, not fixed market rates. The final fee may depend on:
- Annual turnover
- Number of monthly transactions
- Number of bank accounts
- VAT scheme and filing frequency
- Number of employees
- Payroll complexity
- Number of directors
- Quality of your existing bookkeeping
- Whether you need regular advice
Ask what could trigger a price increase. For example, some firms review fees when your transaction volume, staff numbers or turnover moves into a different service tier.
Also ask whether you pay monthly throughout the year or receive a separate year-end bill. A fixed monthly package may make budgeting easier, but only if the scope is clear.
4. Will they help with Corporation Tax and tax planning?
Every UK limited company must prepare annual accounts and file a Company Tax Return. Corporation Tax is calculated on taxable profits, and your company may be able to claim relevant allowances or reliefs.
Your accountant should explain:
- How they calculate your taxable profit
- When your Corporation Tax payment is due
- Which expenses and allowances may apply
- How salary and dividends will be reviewed
- Whether pension contributions or capital purchases may affect planning
- What records they need from you
- How they will warn you about upcoming liabilities
According to GOV.UK guidance on limited company accounts and tax returns, annual accounts are generally due at Companies House nine months after the company’s financial year-end. Corporation Tax is commonly due nine months and one day after the end of the accounting period, while the Company Tax Return is normally due within 12 months.
Your accountant should help you plan for these dates rather than simply remind you after the deadline is approaching.

5. Which accounting software do they use?
Digital accounting is now central to running a modern SME. Ask which platforms the accountant supports, such as Xero, QuickBooks, Sage or FreeAgent.
Then ask:
- Is the software included in the monthly fee?
- Will you set up bank feeds and automated rules?
- Who checks the bookkeeping?
- Can I access the accounts at any time?
- How are receipts and invoices stored?
- Will I receive monthly reports?
- Can the system integrate with our bank, payroll or sales platform?
- What happens to the software account if we leave?
A good accountant should be able to recommend software based on your business: not simply promote the platform they happen to use.
You should also ask how they manage Making Tax Digital (MTD). All VAT-registered businesses must keep digital records and submit VAT returns through compatible software. While MTD for Income Tax mainly applies to sole traders and landlords, a company director with separate self-employed or property income may need additional support. You can review the latest HMRC MTD guidance.
6. How often will you receive advice and reports?
Compliance is essential, but growing businesses often need more than year-end accounts.
Ask whether the accountant provides:
- Monthly or quarterly management accounts
- Profit and loss analysis
- Cash-flow forecasts
- Budget comparisons
- Key performance indicators
- Debtor and creditor reviews
- Tax payment planning
- Support with pricing or margins
- Funding and finance preparation
Find out how often you will meet and what those meetings will cover. A quarterly review call may be enough for one business, while a fast-growing company may need monthly reporting.
It is also worth asking about response times. Will routine questions be answered within 24 or 48 hours? Who should you contact if your usual accountant is unavailable?
7. Are they properly qualified, regulated and insured?
Ask about professional qualifications and regulation. Many UK accountants are members of professional bodies such as:
- ICAEW
- ACCA
- CIMA
- AAT
- CIOT
Membership does not automatically guarantee that a firm is right for your business, but it can indicate that the firm works within professional standards. Ask whether they hold professional indemnity insurance and whether they use an engagement letter explaining the services they provide.
You can also use the ICAEW guide to hiring an accountant as a useful reference when assessing firms.
8. What happens during onboarding: and if you leave?
A professional onboarding process should be clear and organised. Ask what information the accountant needs, how they will obtain records from your previous accountant and how long the transition normally takes.
You may need to provide:
- Company and director details
- Previous accounts and tax returns
- HMRC agent authorisations
- Bank statements
- Bookkeeping access
- Payroll records
- VAT information
- Details of loans, assets and shareholders
Before signing, ask about notice periods and the process for leaving. Confirm that you will receive your records promptly and understand who owns the cloud accounting subscription and data.
Your accountant comparison checklist
Before choosing a firm, compare each proposal using the same questions:
- Does the accountant specialise in limited companies and growing SMEs?
- What exactly is included in the monthly fee?
- Which services are charged as extras?
- Does the price start from £85pm+, and how could it change?
- Who will be your main point of contact?
- What is their response time?
- Which software do they support?
- How will they manage VAT and MTD requirements?
- What tax planning and business advice is included?
- What happens if you change your business structure or grow quickly?
- Are they qualified, regulated and insured?
- What are the onboarding and exit arrangements?
If you use the same checklist with two or three firms, it becomes much easier to compare accountants for small business needs without being distracted by headline pricing.
Ready to find the right accountant?
The best accountant is not necessarily the cheapest. It is the one that understands your company, explains its fees clearly, keeps you ahead of deadlines and gives you useful advice as the business grows.
