Missing a Companies House deadline is more serious than simply being a few days late with paperwork. Depending on what you failed to file, you could face a financial penalty, a company record showing overdue filings, enforcement action, or, in persistent cases, the risk of your company being struck off the register. The good news is that missing a deadline does not automatically mean your company is going to be closed. In many cases, the best response is straightforward: file the outstanding document as quickly as possible, deal with any penalty, and put a system in place to prevent another missed deadline.

This guide explains what happens when a UK company misses a Companies House deadline, including late accounts, confirmation statements and other statutory filings, and what directors should do next.

Important: Companies House deadlines and penalties can change. The guidance below reflects current official information available in 2026. For a specific filing or penalty, check your company's record and the latest guidance from Companies House.

What Is a Companies House Deadline?

A Companies House deadline is the date by which a company must deliver a required document or filing to the registrar. Companies House maintains the public register of companies in the UK. Limited companies have ongoing legal obligations to keep information on that register up to date. Common filings include:

• Annual accounts
• Confirmation statements
• Changes to directors
• Changes to the registered office
• Changes to people with significant control (PSCs)
• Changes to company information
• Certain shareholder and share-capital filings

Not every filing has the same deadline. The consequences of missing one also depend on what was due. For most companies, however, annual accounts are the filing where missing the deadline can create an immediate financial penalty.

What Happens If You File Your Company Accounts Late?

For a private limited company, annual accounts are normally due nine months after the end of the company's financial year. New companies have different rules for their first accounts. Generally, first accounts must be filed within 21 months of incorporation where the relevant first accounting period is longer than 12 months. If acceptable accounts arrive at Companies House after the deadline, a late filing penalty is automatically imposed.

Current Companies House late filing penalties

For a private company or LLP, the standard penalties are:

The penalty is doubled if the company's accounts are late in two successive financial years under the applicable rules. So a delay that initially looks relatively minor can become expensive if it continues.

Example

Suppose a company's accounts are due on 30 June. If the company files acceptable accounts on 15 July, it is more than one day late but within one month, resulting in a £150 penalty. If the company waits until October, the penalty can move into the £375 bracket. The important lesson is simple: once the deadline has passed, don't wait for the penalty notice before filing.

What If Your Accounts Were Filed on Time but Rejected?

This is an important detail that catches some business owners by surprise. Companies House must receive acceptable accounts, not merely receive something that was submitted before the deadline. If accounts are rejected and the filing deadline has already passed, correcting and resubmitting them after the deadline can result in a late filing penalty. Companies House specifically advises companies to submit accounts sufficiently early to allow for problems with the filing.

For example, submitting accounts at 11:50pm on the deadline day leaves virtually no room to fix an unexpected rejection. For this reason, a sensible business practice is to treat the official deadline as the latest possible date, rather than the date you intend to file.

What Happens If You Miss a Confirmation Statement Deadline?

A confirmation statement is different from annual accounts. Every company, including dormant and non-trading companies, must file a confirmation statement at least once every year. Its purpose is to confirm that the information Companies House holds about the company is correct and up to date. You generally need to file one even if nothing about the company has changed. The confirmation statement can cover information such as:

• Registered office details
• Directors
• Company secretary, where applicable
• Shareholders and share structure
• People with significant control
• Principal business activities
• Other information held on the register

If you miss the confirmation statement deadline, Companies House may issue a financial penalty and can take steps towards striking the company off the register. This makes a missed confirmation statement different from simply forgetting an administrative task. It can eventually put the company's legal existence at risk.

Can Companies House Strike Off a Company for Missing Filings?

Yes. If Companies House believes that a company is no longer carrying on business or is not operating, it can begin the process of striking the company off the register. Persistent failure to file required documents can therefore have much more serious consequences than a late filing fee.

If a company is struck off and dissolved, it ceases to exist as a legal entity. Company assets can also be affected; Companies House warns that assets, including property and money in a bank account, may pass to the Crown. This is particularly important for founders who have created a company but have not started trading yet.

"My company is dormant" does not mean "I have nothing to file"

A dormant company still has filing obligations. A dormant company generally still needs to file:

• Annual accounts
• A confirmation statement

Companies House explicitly states that dormant and non-trading companies must continue to meet these requirements. So putting a company on hold does not automatically remove its Companies House responsibilities.

Are Companies House Filing Deadlines the Same as HMRC Tax Deadlines?

No. This is one of the most important distinctions for company directors. Companies House and HMRC are separate authorities with different filing obligations and deadlines. For a typical private limited company:

These deadlines are not interchangeable. For example, filing your accounts with Companies House does not automatically mean every HMRC requirement has been satisfied. Some accounting software and professional services can coordinate filings, but directors should still understand which obligations are being dealt with and by whom.

What Happens If You Miss an HMRC Deadline as Well?

If the missed deadline relates to your Corporation Tax return rather than Companies House, HMRC penalties apply separately. For a late Company Tax Return, the standard penalty starts at £200 after one day. A further £200 can apply after three months, with additional penalties possible after six and 12 months.

This means one badly managed accounting deadline can potentially create problems with both Companies House and HMRC. A company director should therefore think about statutory compliance as one connected calendar rather than treating Companies House and HMRC as completely separate administrative tasks.

What Should You Do If You Have Already Missed the Deadline?

The worst response is usually to ignore it. Instead, follow this sequence.

1. Check exactly what is overdue

Search for your company using the official Companies House service and check:

• Which filing is overdue
• The original deadline
• Whether a penalty has been issued
• Whether there are other overdue documents
• Whether the company has received a strike-off notice

Don't assume the problem is limited to the document you already know about. One missed filing can sometimes be accompanied by another upcoming or overdue obligation.

2. File the outstanding document immediately

If you have not yet submitted the required document, deal with that first. For accounts, make sure the accounts are complete and meet the relevant filing requirements. Filing an incomplete or incorrect document simply to "get something in" can create additional problems. Companies House states that the accounts must be acceptable, and rejected accounts may still result in a penalty if the deadline has already passed.

3. Deal with the penalty

If a late filing penalty has been issued, don't ignore it. Companies House allows eligible penalties to be paid online, and payment instructions are provided on the penalty notice. If paying immediately is difficult, Companies House says it will normally accept requests for payment by instalments over a short period where appropriate.

4. Consider whether an appeal is justified

A late filing penalty can be appealed, but simply having a good excuse is not enough. Companies House generally expects evidence of exceptional circumstances or an error by Companies House itself. Examples that may support an appeal include an unforeseen serious event occurring close to the filing deadline or circumstances outside the company's control. By contrast, the following generally aren't enough on their own:

• You forgot
• You did not know about the deadline
• Your accountant missed it
• You were travelling
• The company was dormant
• You could not afford the penalty
• The accounts were your first accounts

Companies House specifically states that relying on an accountant does not remove the director's responsibility for filing. If you appeal, provide a clear explanation and supporting evidence.

Can You Get a Companies House Deadline Extension?

For accounts, an extension can sometimes be requested before the filing deadline has passed where there is an exceptional reason. Companies House guidance states that extensions are only granted in exceptional circumstances. This is why directors should not wait until after the deadline to ask for additional time. If the deadline has already passed, the more practical priority is usually to complete and file the outstanding accounts as quickly as possible and then deal with the resulting penalty or other consequences.

Who Is Responsible for a Company's Filing Deadlines?

Ultimately, the legal responsibility sits with the company's directors. You can appoint an accountant, company secretary or professional company formation and management provider to help manage compliance, but outsourcing the work does not automatically transfer the legal responsibility away from the directors. This is an important distinction for founders who operate internationally. A director living outside the UK, for example, remains responsible for ensuring the UK company meets its filing obligations.

How to Avoid Missing Companies House Deadlines

The simplest solution is to build compliance into your normal business operations.

Create a statutory calendar

Record:

• Accounts deadline
• Confirmation statement date
• Corporation Tax deadlines
• VAT deadlines, if registered
• PAYE deadlines, if applicable
• Other sector-specific regulatory obligations

Do not rely exclusively on memory.

Set reminders well before the deadline

A useful approach is to create reminders at:

• 90 days
• 60 days
• 30 days
• 14 days
• 7 days

The earlier reminders should trigger preparation, not simply remind you that something is due.

Keep Companies House information current

Make sure Companies House has an address where official correspondence can actually reach you. If you change your registered office, directors or other company information, update the register promptly.

Don't leave filing until the final day

This is especially important for accounts. Technical problems, rejected submissions, missing information or accounting questions can turn a straightforward filing into a last-minute crisis.

A Practical Compliance Framework for Company Directors

A useful way to manage a UK company is to divide obligations into three categories.

Monthly: Monitor

Review transactions, bookkeeping, correspondence and upcoming statutory obligations.

Quarterly: Prepare

Review financial information, tax obligations and corporate changes. If you use an accountant, this is a good point to resolve outstanding questions rather than waiting for year-end.

Annually: File and verify

Complete annual accounts, confirmation statement and relevant tax filings, then verify that the public company record is accurate. This approach turns compliance from an emergency task into a routine business process. For international founders, having a UK company formation and management platform such as IncorpUK involved in the administrative side can also provide an additional layer of organisation, particularly when the founders are managing the business from outside the UK.

What If Your Company Has Already Received a Strike-Off Notice?

Act quickly. A strike-off notice should never be treated as ordinary correspondence. Check why the action has started and identify every outstanding filing. If the company is still operating, you should address the underlying compliance issue rather than simply waiting for further correspondence.

If the company has already been struck off, restoring it can involve additional procedures, costs and legal considerations. Companies House also distinguishes between unpaid penalties that arose before dissolution and penalties associated with accounts that were overdue at the time of restoration. Where valuable assets, contracts, employees, property or significant liabilities are involved, professional legal or accounting advice is particularly important.

Frequently Asked Questions

What happens if I file my Companies House accounts one day late?

For a private company, a late filing penalty normally applies once acceptable accounts are received after the deadline. The current penalty for accounts filed no more than one month late is £150.

Can Companies House fine me for a late confirmation statement?

Yes. Companies House may issue a financial penalty for failing to file a confirmation statement on time and can take steps towards striking the company off the register.

What if my accountant missed the Companies House deadline?

The company and its directors remain responsible for ensuring the filing is made. Relying on an accountant is generally not considered sufficient grounds by itself for successfully appealing a late filing penalty.

Can I appeal a Companies House late filing penalty?

Yes, but successful appeals are generally based on exceptional circumstances or an error by Companies House. You should provide evidence supporting your explanation.

Does a dormant company have to file with Companies House?

Yes. Dormant companies generally still have to file annual accounts and a confirmation statement.

Can Companies House close my company for missing a deadline?

Persistent failure to meet filing obligations can lead Companies House to start strike-off proceedings. If the company is struck off and dissolved, it ceases to exist as a legal entity.

Are Companies House and HMRC deadlines the same?

No. Companies House and HMRC have separate filing requirements and deadlines. For example, a private company's annual accounts are generally due at Companies House nine months after the financial year end, while a Company Tax Return is generally due to HMRC 12 months after the Corporation Tax accounting period ends.

Can I get more time to file my accounts?

In exceptional circumstances, you can apply for an extension before the accounts deadline passes. Companies House states that extensions are only granted in exceptional circumstances.

Conclusion: Don't Turn a Late Filing Into a Bigger Problem

Missing a Companies House deadline is not something to panic about, but it is something to act on. For late accounts, penalties can start at £150 for a private company and increase substantially as the delay continues. Repeated or serious non-compliance can also expose the company to enforcement action and possible strike-off. The best response is therefore straightforward:

Check what is overdue, file it correctly as soon as possible, deal with any penalty, and establish a reliable compliance calendar. Most importantly, remember that Companies House compliance is an ongoing responsibility. Whether your company is actively trading, dormant, UK-based or managed by founders overseas, its statutory obligations do not disappear.

For entrepreneurs building a UK company, good compliance is more than avoiding fines. It protects the company's legal standing, keeps its public record credible and gives customers, banks, investors and business partners confidence that the business is being properly managed.
