One of the most common questions we hear from new directors is whether they actually need an accountant for a limited company, or whether modern software makes it something they can handle themselves. It is a fair question, and the answer is not as simple as most articles make it sound.

Legally, there is no requirement for a UK limited company to engage an accountant. Companies House does not mandate it, and HMRC does not require it. So if that is all you wanted to know, the answer is: no, you do not have to.

But we rarely stop there, because the legal position and the practical reality are quite different things. Running a limited company generates a specific set of compliance obligations — Corporation Tax returns, annual accounts, confirmation statements, payroll, and more — and the cost of getting any of them wrong has just gone up. From April 2026, HMRC introduced new penalties for late Corporation Tax filings that make the margin for error considerably smaller. The question is less 'do I need one' and more 'what does it actually cost me not to have one'.

A lot of directors, particularly those setting up their first limited company, underestimate what the ongoing compliance workload involves. It is not just filing a tax return once a year.

A typical limited company director is responsible for:

• Preparing and filing statutory accounts with Companies House each year
• Submitting a Corporation Tax return (CT600) to HMRC, separately from the accounts
• Filing a confirmation statement annually via Companies House
• Running PAYE payroll if the director takes a salary, with associated RTI submissions
• Submitting VAT returns if the company is VAT-registered — typically quarterly
• Preparing a personal Self Assessment return for any dividend income or benefits

Each of these has its own deadline, its own filing format, and its own penalty regime for errors or late submission. Miss the Corporation Tax deadline and HMRC will issue an automatic £100 penalty — and under the rules that came into force in April 2026, the points-based penalty structure for late filing means repeat issues compound quickly.

None of this is insurmountably complex, but it is also not the kind of admin that sits comfortably on top of actually running a business. The question to ask yourself honestly is: how much time are you spending on it, and what is that time worth to you?

Most of the pushback we hear on hiring an accountant comes down to cost. And we understand that — when you are running a lean operation, every monthly outgoing gets scrutinised.

But there are two things worth putting alongside the fee figure. First, accountancy fees are a deductible business expense. If your company pays the fee, it reduces your taxable profit — which means the net cost to you is meaningfully lower than the headline number. For a company paying Corporation Tax at the small profits rate of 19%, a £100 monthly fee has an after-tax cost closer to £81.

Second, and more importantly, a decent accountant is not just a filing service. The directors we work with who get the most value from the relationship are the ones who use it actively — asking questions about dividend timing, salary structuring, expense treatment, and how their numbers are trending. That kind of ongoing input is what makes the fee feel irrelevant rather than burdensome.

We have had clients tell us the tax savings from a single conversation about salary and dividend split covered their fees for the year. We are not in the business of making grand promises, but the principle is sound: a management-accounting-qualified adviser who understands your company's numbers tends to surface opportunities that a director working alone does not.

For a sense of what fees look like in the market, our guide to the cost of an accountant for a limited company covers typical ranges and what drives the variation.

We should be honest here: there are situations where a director managing their own accounts is entirely reasonable, at least for a period.

If your limited company is dormant or newly formed with minimal activity, the compliance burden is low. A dormant company files abbreviated dormant accounts and a nil Corporation Tax return — both are straightforward, and the risk of error is limited. Many founders keep a company shell ticking over themselves in the early stages, which is sensible.

Similarly, if you have a strong finance background and genuinely understand what you are doing, the case for outsourcing is weaker. We have worked with directors who maintained their own books competently for years before bringing us in when the business grew to the point where it needed management reporting and forecasting rather than just compliance.

The hybrid approach is also worth considering: use cloud accounting software — Xero is our preferred platform — to handle day-to-day bookkeeping and transaction coding yourself, then bring in an accountant for the statutory year-end work, Corporation Tax, and anything that requires professional judgement. That keeps costs down without leaving you entirely exposed on the compliance side.

The risk with any DIY approach is not usually the routine filing — it is the things you do not know you do not know. Miscoding a personal expense as a business one, missing a VAT election that would save money, or structuring a dividend payment at the wrong point in the year. These are the gaps that accumulate quietly.

This is worth flagging specifically for directors who have been managing their own Corporation Tax to date.

From April 2026, HMRC moved to a points-based penalty system for late Corporation Tax returns, aligning it broadly with the existing regime for Self Assessment and VAT. Under the new rules, each late filing accrues a penalty point, and once a threshold is reached, financial penalties apply — with the risk of escalating charges for continued non-compliance.

The practical effect is that a pattern of slightly-late filings, which may previously have generated a single £100 penalty and been forgotten about, now accumulates in a way that is harder to reset. Directors who have relied on filing a few weeks late with minimal consequence should treat that approach as closed.

We are not raising this to be alarmist. But the timing is relevant: if you have been on the fence about whether to bring in an accountant for your limited company, the changed penalty landscape is a concrete reason to move sooner rather than later. Getting a proper filing calendar in place, with a professional responsible for hitting the deadlines, is considerably cheaper than managing a growing penalty position.

If you want to understand the full detail of your company's filing obligations, HMRC's guidance and the Companies House filing requirements are both worth reading alongside professional advice.
