Do I need an accountant? When software is enough and when it isn't

Plenty of small businesses start with accounting software and a spreadsheet, and for a simple set-up that can work perfectly well. The harder question is when it stops being enough. This guide sets out what software does well, where it runs out, and the signs that a professional is worth paying for.

Modern accounting software is good at the routine parts: recording sales and costs, matching bank transactions, sending invoices, and producing a basic profit and loss. If you are a sole trader with one source of income and straightforward expenses, it may be all you need.

The limit is that software answers the questions you know to ask. It rarely tells you about the ones you did not know existed.

You are more likely to benefit from an accountant once things like these appear:

\- **A limited company.** You have accounts and a Company Tax Return to prepare, a Confirmation Statement, and decisions about salary, dividends and pensions. - **More than one income source.** Employment, a business, rental income, dividends or a second company. - **Growth.** More staff, more customers, stock, or sales that no longer fit comfortably in a spreadsheet. - **VAT.** Choosing when to register, which scheme to use, and getting returns right. See our guide to [VAT registration](/vat-registration). - **Property.** Rental income, or a company that owns or lets property. - **Investors, lenders or a sale on the horizon.** They will want reliable monthly numbers, not just year-end accounts. - **A change in the rules.** For example, [Making Tax Digital for Income Tax](/making-tax-digital-income-tax) will change how many sole traders and landlords keep records and report to HMRC.

None of these means you cannot do it yourself. They mean the cost of a missed item or a wrong assumption goes up.

Preparing accounts and tax returns is compliance: recording what has already happened and filing it on time. A competent accountant does that, but the greater value usually comes from planning, which happens before the deadline rather than during the rush to file.

Planning questions look like this:

\- Is the mix of salary and dividends right for this year? - Should we buy the equipment before or after the year end? - Will there be enough cash for the tax bill, and when? - Is it time to register for VAT, or to move to a different scheme? - What will the business look like in twelve months, and what finance does it need?

Software cannot raise these for you. They are the questions a good accountant asks without being prompted.

For a UK private limited company, GOV.UK sets out these deadlines:

Late filing can lead to penalties from both Companies House and HMRC. Check [GOV.UK](https://www.gov.uk/prepare-file-annual-accounts-for-limited-company) for the current rules for your situation.

\- **Spots what you missed.** Reliefs, allowances and expenses you did not know you could claim, or errors in earlier years that need correcting. - **Checks the judgement calls.** Is this an expense or an asset? Is this person an employee or a contractor? - **Plans ahead.** Tax, cash and growth, with time to act rather than a surprise bill. - **Deals with HMRC and Companies House** on your behalf. - **Explains the numbers.** Good management accounts tell you what changed and what to do about it. See [management accounts explained](/management-accounts-explained).

You probably still manage without an accountant if:

\- You are a sole trader with one source of income, and your records are up to date. - You are not VAT registered, or are well below the threshold. - You are comfortable filing your own return, and nothing has changed since last year.

You should at least talk to one if:

\- You have recently started a limited company, or are about to. - You have been putting off your bookkeeping, or are not sure it is right. - A new income source, hire, property or investor has appeared. - You are making decisions about tax or cash and you are guessing.

The honest answer depends on the business. The aim is not to pay for an accountant for the sake of it, but to be sure the money spent on advice is less than the cost of errors, missed claims, late filing penalties or poor decisions. A short conversation costs little, and a good accountant will tell you plainly if you do not need one yet.
