Yes. Any business owner can keep their own books and file their own returns, and many sole traders do exactly that for years without trouble. The law cares that your records are adequate and your returns accurate, not who prepared them. So the useful question is not “am I allowed?” but “is this the right job for me to take on?” That comes down to four things: capability, time, risk and complexity.

What the job actually involves

“Doing the accounts” is shorthand for several distinct tasks, and it helps to see them separately:

  1. Record-keeping: logging every sale, purchase and business expense, and keeping the evidence. GOV.UK sets out what self-employed records must cover and how long to keep them.
  2. Reconciliation: checking your records against bank statements so nothing is missed or duplicated.
  3. Returns: turning those records into whatever filings your structure requires, from Self Assessment to company accounts.
  4. Interpretation: knowing which expenses are allowable, which reliefs apply, and what the rules mean in your case.

Most DIY problems start in task four. The mechanics are learnable; judgement is what takes experience.

An honest self-test before you commit

Ask yourself:

  • Do I actually understand which of my costs are allowable, or am I guessing?
  • Have I read the relevant GOV.UK pages, or only skimmed forum posts?
  • Do I record transactions weekly, or shove receipts in a drawer for January?
  • If HMRC asked me to justify a figure, could I show the working?
  • Am I doing this to save money, or because I genuinely want to?

Two or more uncomfortable answers is a sign that DIY may cost you more than it saves: in tax overpaid, claims missed or errors made.

The time cost nobody budgets for

Bookkeeping is rarely hard; it is relentless. An hour a week sounds trivial until it competes with paid work, family and everything else. The pattern we see most often is not bad DIY accounting but abandoned DIY accounting: tidy records until spring, chaos by autumn, and a stressful reconstruction before the filing deadline. If you charge for your time, multiply your hourly rate by the hours this takes and compare it with a bookkeeping fee. The arithmetic is often closer than expected.

Where software helps and where it stops helping

Cloud accounting software genuinely lowers the barrier. Bank feeds capture transactions, invoices generate themselves, and the arithmetic is handled for you. What software cannot do is exercise judgement. It will happily let you claim a disallowable expense, miscategorise a capital purchase or misunderstand a VAT rule, and it will present the wrong answer just as confidently as the right one. Treat software as a diligent assistant, not a safety net.

When complexity quietly outgrows you

DIY tends to stop being sensible not on a single day but by accumulation. Warning signs include registering for VAT, taking on your first employee, incorporating, earning from more than one source, or holding stock. Each adds rules that interact with the others. If you are unsure whether you have crossed that line, the pillar guide on whether your small business needs an accountant walks through the full decision.

A middle route most people overlook

This is not all-or-nothing. Common hybrid arrangements include:

Each keeps costs down while putting a second pair of eyes where errors are most expensive.

Frequently asked questions

Do I need any qualification to do my own accounts?

No. There is no licence or qualification required to keep your own records or file your own returns.

What records does HMRC expect me to keep?

Records of all income and expenses, plus supporting evidence, kept for the period set out in current GOV.UK guidance. The exact list depends on your structure and whether you are VAT registered or an employer.

If I make an honest mistake, what happens?

You can usually correct a return after filing. Errors can still lead to interest or penalties depending on the circumstances, which is why accuracy matters even when intentions are good.

Is spreadsheet bookkeeping still acceptable?

For some businesses, yes; others are required to keep digital records under Making Tax Digital rules. Check current GOV.UK guidance for your situation before settling on a method.

Can an accountant take over mid-year if I give up?

Yes, and it happens all the time. The tidier your records at handover, the less catching-up you pay for.
