If you run a limited company, preparing and filing your annual accounts is a legal requirement, not an optional admin task. This guide explains exactly what is involved, when it is due, what happens if you miss the deadline, and how to decide whether to handle it yourself or bring in help.

Why limited company compliance has more moving parts in 2026

As a limited company director, you are legally required to prepare statutory accounts every year and send them to your shareholders, Companies House, and HMRC. Those accounts must include a balance sheet, a profit and loss account, notes to the accounts, and in most cases a director’s report. The balance sheet must carry a director’s printed name and signature.

The reporting requirements are becoming more detailed. In March 2026, HMRC opened a consultation on new obligations for close companies, which are companies controlled by five or fewer participators or any number of participators who are also directors. From the 2025-26 tax return onwards, directors of close companies will need to provide additional information about transactions between the company and its shareholders. You can read the full details on GOV.UK.

Where directors run into problems

Most filing errors do not come from a lack of effort. They come from not knowing which deadline applies to which body, or from keeping records throughout the year in a way that makes preparing the accounts difficult when the time comes.

Treating Companies House and HMRC as the same deadline

Many directors assume there is one filing and one deadline. There are two. Your statutory accounts go to Companies House at the 9-month mark. Your corporation tax return and any accompanying accounts go to HMRC at 12 months. Filing late with Companies House triggers automatic penalties starting at £150 for a private company and rising to £375 at three months, with higher charges after that. As discussions on UK Business Forums confirm, some directors are caught off guard even when they thought they had more time.

Poor records throughout the year

Statutory accounts can only be as accurate as the records behind them. If your income and expenses have not been tracked in a consistent, organised way, preparing accounts at year end takes significantly longer and increases the chance of errors. According to the DNS CloudCo analysis of limited company structures, the increased administrative responsibility of running a limited company catches many directors off guard, particularly those who recently moved from sole trader status.

What preparing limited company accounts actually involves

The process has three practical stages. Working through each one in order makes the whole thing manageable. Trying to do them all at once in the final weeks before a deadline is where things go wrong.

1. Record-keeping throughout the year: Every transaction your company makes needs to be recorded accurately. I use Xero for this, which means your records are live, cloud-based, and ready to work with when accounts preparation begins. If you are not currently using accounting software, this is the first thing to address.
2. Preparing the statutory accounts: This means producing a compliant balance sheet, profit and loss account, and the required notes. The balance sheet must be signed by a director. The accounts must meet either International Financial Reporting Standards or New UK Generally Accepted Accounting Practice. For most small companies, FRS 105 (micro-entity) or FRS 102 (small company) will apply.
3. Filing with Companies House and HMRC: Your accounts go to Companies House within 9 months of year end. Your corporation tax return, along with a copy of the accounts, goes to HMRC within 12 months. If your records are clean and the accounts have been prepared properly, this stage is straightforward. If they are not, this is where the delays and stress pile up.

If your records are behind or your year end has already passed, that is not a reason to delay further. I have worked with clients whose bookkeeping was months behind when we started. Getting things in order takes time, but it is always possible.

Comparing your options on cost and risk

There are three realistic approaches to limited company accounts: doing it yourself, using a large accountancy firm, or working with a dedicated sole-trader bookkeeper who handles it personally. Each carries different costs and different levels of risk. The table below sets out the practical differences.

What to do next if your accounts need attention

Whether your year end is approaching or you are already overdue, there are concrete steps you can take right now. The worst outcome is waiting. Penalties at Companies House start the day after the deadline and they do not disappear by ignoring them.

• Find your company’s accounting reference date: This is the last day of the month in which your company was incorporated, unless you have changed it. Your year end accounts are built around this date. You can confirm it on the Companies House register at no cost.
• Check whether your records are Xero-ready: If your income and expenses are already being tracked in Xero, preparing your accounts will be faster and cleaner. If you are using spreadsheets or paper, now is the time to consider migrating. I set up and manage Xero for clients across Suffolk as part of my standard service.
