If you’ve recently set up a limited company — or you’re in the process of doing so — chances are you’ve asked yourself whether you genuinely need an accountant for a limited company, or whether it’s something you can handle yourself. The short answer is that there’s no legal requirement to hire one. Companies House and HMRC don’t mandate it.

But legal requirement and good idea are two very different things. In our experience working with limited company directors, the more useful question isn’t “do I have to?” — it’s “what am I actually taking on if I don’t?” The filing obligations, the tax decisions, and the personal liability that comes with being a director add up quickly, and most people underestimate them when they’re starting out.

We’ll give you our honest view: most limited company directors benefit from professional support, and we’ll explain why. But we’ll also be straight about when managing your own accounts can work — because it sometimes does.

Let’s get this out of the way first. There is no legal obligation to use an accountant to run a limited company in the UK. You can prepare your own annual accounts, file your own Corporation Tax return (CT600), and submit your own confirmation statement to Companies House — all entirely within the rules.

The same applies regardless of your company size, with one notable exception: if your company grows large enough to require a statutory audit, you’ll need a registered auditor. Most small and micro-entity companies won’t reach that threshold. Micro-entities — those with turnover below £632,000, a balance sheet under £316,000, and fewer than ten employees — can file simplified accounts and are not required to have them professionally audited.

So the choice is genuinely yours. What the law does require, however, is that your filings are accurate and on time. Your accounts must be filed with Companies House within nine months of your financial year end. Corporation Tax must be paid within nine months and one day of your accounting period ending. The director — meaning you — remains personally responsible for meeting those deadlines, whether you prepared the accounts yourself or had someone do it for you. That last point is worth sitting with for a moment.

Most people who ask whether they need an accountant for a limited company are thinking about year-end accounts and a tax return. That’s understandable — it’s what most of the conversation focuses on. But the compliance picture for a limited company is broader than that, and it catches a lot of new directors off guard.

Here’s what you’re typically responsible for as a director:

• Annual accounts filed with Companies House within nine months of your year end
• Corporation Tax return (CT600) filed with HMRC within 12 months of your accounting period end, with tax paid within nine months and one day
• Confirmation statement filed with Companies House at least annually
• VAT returns if you’re VAT registered — quarterly for most businesses, and increasingly subject to Making Tax Digital requirements
• Payroll and PAYE if you’re paying yourself a salary through the company, even if it’s just a director’s salary
• Self Assessment for your personal income, including dividends drawn from the company

Each of these has its own deadlines, its own rules, and its own penalties for getting it wrong. None of it is impossible to learn, but it’s a meaningful body of knowledge — and the rules change regularly. If you’re running a business at the same time, it’s a real question whether your time is better spent elsewhere.

We see the same patterns repeat themselves. Directors who manage their own accounts tend to struggle not with the routine filings but with the decisions that sit around them.

Dividend planning

One of the main tax advantages of operating through a limited company is the ability to structure your income as a mix of salary and dividends. Getting that balance right — and understanding how it interacts with your Corporation Tax position, your personal tax position, and National Insurance — is where a lot of value either gets captured or lost. It’s not obvious, and it changes year to year as thresholds shift.

Expenses and what’s allowable

Limited companies can claim a wider range of business expenses than sole traders, but the rules on what’s deductible aren’t always intuitive. Home office costs, mileage, equipment, and professional subscriptions all have specific treatment. Getting this wrong means either overpaying tax or — worse — claiming things you shouldn’t and creating a problem with HMRC later.

Late filing penalties

Companies House penalties for late accounts range from £150 to £1,500 for private companies, and they double if you’re late two years running. HMRC penalties for a late CT600 start at £100 and can escalate to 10% of unpaid tax if the delay is significant. These aren’t catastrophic sums on their own, but they’re entirely avoidable — and they do compound.

We want to be fair here. There are situations where managing your own limited company accounts is a reasonable choice, at least for a while.

If your company is dormant or has very minimal activity — perhaps you’ve set it up in preparation for a future project — the filing requirements are straightforward and the risk of error is low. A dormant company still needs confirmation statements and dormant accounts filed, but these are simple.

Some directors also have a genuine accounting background. If you’ve worked in finance, understand double-entry bookkeeping, and are comfortable with HMRC’s online systems, you may find the compliance manageable. The caveat is that even experienced accountants often use a separate adviser for their own affairs, precisely because it’s hard to be objective about your own numbers.

Cloud accounting software has also made a real difference. Platforms like Xero can automate a significant chunk of the bookkeeping work and keep your records tidy throughout the year. That said, software handles data — it doesn’t make tax decisions for you, and it won’t spot an opportunity to reduce your Corporation Tax bill or flag that your director’s loan account is heading somewhere problematic.

In our view, the question isn’t really whether you can do it yourself. It’s whether you should be the person spending time on it — and whether you’re confident you’re not missing anything that costs you more in the long run.
