Most directors arrive in their role without formal accounting training, yet the law holds them personally responsible for filing accurate accounts on time. This guide explains your legal duties, the real consequences of getting it wrong, and what you can do to stay on the right side of Companies House and HMRC.

Why accounting for directors matters more than most people realise

Being appointed a director is not just a job title. Under the Companies Act 2006, you are personally and legally responsible for keeping company records, preparing annual accounts, filing a Company Tax Return, and paying Corporation Tax on time. You can hire an accountant to manage the day-to-day work, but the legal responsibility stays with you regardless.

This distinction trips up a lot of directors. Many assume that because a firm of accountants is involved, they are shielded from liability. That is not how the law works. If accounts are filed late or incorrectly, it is the director who faces penalties, prosecution, or disqualification.

Where most directors go wrong

The most common errors are not rooted in dishonesty. They come from confusion about what is actually required and by when. Directors often assume someone else is keeping track of deadlines, or that a missed filing is a minor administrative slip rather than a criminal matter.

Assuming the accountant handles everything automatically

An accountant can manage your filing obligations on your behalf, but you must provide accurate information and approve what is filed. GOV.UK is clear that directors remain legally responsible for the company’s records, accounts and performance, even where professionals are engaged. If your accountant files incorrect accounts because you gave them incomplete information, the liability is still yours.

Overlooking the confirmation statement

The confirmation statement is an annual filing that confirms the information Companies House holds about your company is correct. It costs £50 to file online and must be filed at least once every 12 months. Every company must file one, including dormant companies. Failure to file can result in a financial penalty of up to £5,000 and the company being struck off the register.

What you are actually responsible for as a director

Your obligations fall into several categories. Understanding them is the first step to staying compliant without unnecessary stress. Here is what you are required to do as a director of a UK limited company.

1. Keep company records accurate and up to date. This includes details of directors, the company secretary, shareholders, and people with significant control (PSCs). Before filing a confirmation statement, you must ensure all of these records are current. Companies House now requires directors to verify their identity and provide a personal code as part of the confirmation statement process. This became a legal requirement on 18 November 2025.
2. Prepare and file annual accounts. Your year-end statutory accounts must be filed with Companies House within nine months of your company’s financial year end. The accounts must show a true and fair view of the company’s finances. You must also prepare and file a Company Tax Return with HMRC and pay any Corporation Tax owed, typically nine months and one day after your accounting period ends.
3. Declare personal interests and tax obligations correctly. If you personally benefit from a transaction the company makes, you must tell other shareholders. As a director taking a salary and dividends, you are also required to complete a Self Assessment tax return each year to declare your personal income from the company. Directors who take money from the company outside of salary or dividends may be subject to Director’s Loan Account rules, including an S455 tax charge on overdrawn balances not repaid within nine months of the year end.

These are not optional activities. GOV.UK confirms that directors may be fined, prosecuted or disqualified if they do not meet their responsibilities. The good news is that none of this needs to be complicated when the right systems are in place.

Costs and what to expect

Directors of limited companies generally have more filing obligations than sole traders, which is reflected in the cost of professional accounting support. At STZ Accounting, limited company packages start from £215 per month on the Bronze tier for turnover up to £100k. That covers monthly bookkeeping, limited company accounts, Corporation Tax, confirmation statement, payroll, Self Assessment for up to two directors, quarterly VAT returns, and monthly management reports. There are no hidden fees and no tie-in contracts. Filing a confirmation statement yourself costs £50 online via Companies House. Getting it wrong, or missing it altogether, can cost considerably more in penalties.

How to get on top of your director responsibilities today

You do not need to become an accountant to fulfil your duties properly. You need clear information, a reliable process, and someone who will tell you what is due and when. Here are the practical steps to take right now.

• Check when your next confirmation statement is due. Log into your Companies House account and confirm the review period end date. If you have not yet completed identity verification, you must do this before your next confirmation statement can be filed. The filing window closes 14 days after your review period ends.
• Find out when your Corporation Tax payment and Company Tax Return deadlines fall. Your Corporation Tax payment is due nine months and one day after your accounting period end. Your Company Tax Return must be filed within 12 months.
