Running a company in the UK comes with responsibilities and one of the most important is filing your annual accounts on time with Companies House. Miss that deadline and you will be hit with a late filing penalty.
And these penalties aren’t small, they can quickly add up and even double if you repeat the mistake the following year.
In this guide, we’ll break down:
- What a Companies House late filing penalty actually is?
- How to Appeal AgainstLate Filing Penalties?
- What Happens if Your Appeal is Rejected?
- The rules around appeals and extensions, and
- Much More…
Let’s get started!
What is a Companies House Late Filing Penalty?
A late filing penalty is a fine that Companies House charges when a company does not send its annual accounts by the deadline.
It makes no difference if the company is trading, dormant or even has very little activity. If it is on the Companies House register the accounts need to be filed. The fine starts small and then keeps getting bigger the longer the delay goes on. A short delay might not hurt much but leaving it for months can become very costly.
Companies House keeps these rules in place to make sure company records are clear for the public, creditors and anyone else who depends on them.
When Does a Late Filing Penalty Apply?
All limited companies registered in the UK must file accounts once a year. The deadline depends on whether it’s your first set of accounts or a subsequent filing:
- First accounts: 21 months after incorporation
- Subsequent accounts: 9 months after your company’s financial year end
Miss these dates and penalties kick in automatically. If you file even one day late, you’ll face a penalty.
Examples of When Penalties Hit
Say your financial year ends on March 31, 2025. As a private company, your deadline is December 31, 2025. File on January 1, 2026, and you’re looking at the base penalty. Drag it to April, and it escalates. Real-life stories from forums like Reddit show directors getting caught out by holidays or bank delays don’t let that be you.
How Much Are Companies House Penalties in 2025/2026?
The penalty is based on how late you are:
- Up to 1 month late → £150
- 1 to 3 months late → £375
- 3 to 6 months late → £750
- More than 6 months late → £1,500
Another important thing to remember is that if you’re late two years in a row, the fine is automatically doubled.
Who is Responsible for Filing Annual Accounts?
The responsibility lies with the company’s directors, not the accountant. Even if you outsource accounting, Companies House holds directors legally accountable for late filing. This means you can’t use “my accountant forgot” as a defence.
How to Appeal Against Late Filings Penalties?
Think the penalty isn’t fair? You can challenge it. Companies House lets you put in an appeal if you had a genuine reason for missing the deadline. The trick is knowing what counts as “genuine” and what doesn’t.
Some reasons get accepted, most don’t. You’ll also need to follow the right process and back up your claim with evidence.
Let’s break it down step by step.
Before you start
Appealing is straightforward in terms of process but success depends on how strong your case is. To start:
- You’ll need to complete a Companies House appeal form (this can be done online or by post).
- Clearly explain why your accounts were late.
- Provide something solid to back up your reason. That could be a doctor’s note, legal paperwork, or proof of a sudden disruption that threw you off track.
What won’t work? A vague story with no evidence. Companies House is very clear about this. They want hard facts and a direct connection between your situation and the missed deadline.
Valid Reasons for Appeal
Companies House accepts very few reasons as valid. Therefore, appeals are only successful if something truly outside of your control happened. Some valid reasons include:
- Illness or bereavement: If a director or someone who handles the accounts became seriously unwell or passed away and this directly delayed the filing.
- Technical glitches: If Companies House systems went down or there was a known fault with their online service when you tried to file.
- Fire, flood, or other disasters: If your business experienced damage that directly impacted your ability to complete accounts.
- Unexpected postal delays: In rare cases, if your accounts were sent in good time but delayed due to postal strikes or loss in transit.
- Other exceptional circumstances: Things outside your reasonable control that made it impossible to file on time.
Reasons That Are Not Accepted
It’s just as important to know what will not be accepted. Companies House publishes a list of reasons that usually fail appeals. These include:
- Being too busy running the business.
- Not being aware of your filing deadline.
- Staff shortages or changes in your team.
- Not receiving a reminder from Companies House.
- Relying on your accountant to file, and they forgot.
- Technical problems on your side (for example, computer issues, forgetting passwords or leaving filing until the last minute).
In short, if the delay could have been avoided with better planning, the appeal is unlikely to succeed.
How to Strengthen Your Appeal?
Here are a few tips to increase your chances If you decide to go ahead with an appeal h
- File your appeal as soon as possible, don’t delay.
- Be clear and specific in your explanation.
- Attach all supporting documents that back up your claim.
- Avoid excuses like “I didn’t know” or “I was too busy.”
The more solid your reasoning and evidence, the more likely Companies House will give your appeal fair consideration.
What if Your Appeal is Rejected?
If Companies House rejects your appeal, you can contest further in court but that’s often costly and rarely successful unless you have strong evidence.
In short, if your appeal gets rejected the penalty will stand and you will need to pay it. You can
- Pay in full by the date on the notice, or
- Request to pay in installments if you are struggling with cash flow.
How to Pay Companies House Late Filing Penalty?
You can pay your penalty in several ways:
- Online by debit or credit card
- Bank transfer (Faster Payments, BACS, CHAPS)
- By cheque (though slower)
Payments must be made in full by the due date unless you’ve agreed on installments.
Can I Pay in Instalments?
Yes. If your company is struggling financially, you may be able to request a payment plan. Contact Companies House as soon as possible to discuss your options.
How Can You Extend Your Annual Accounts Deadline?
Life happens. Sometimes things go wrong and it’s not in your control. Maybe a director fell seriously ill. Maybe a flood damaged your office. In cases like that, you can ask Companies House for extra time but you need to do it before the deadline.
It’s not for general delays. They won’t give you an extension just because you forgot or got busy. It’s only for real emergencies.
For 2025/2026 the process is still the same. Apply early, explain clearly, add proof. They’ll decide if your reason is strong enough. Nothing is guaranteed.
Steps to Apply for an Extension
- Log into Companies House online service
- Fill out the form with your reason
- Attach any documents that back it up
- Submit
They usually reply in 5 to 10 working days. If denied, file ASAP to minimize penalties.
What Are the Consequences of Not Filing at All?
Late filing is serious but not filing at all is far worse. Beyond the financial fines, directors can face:
- Company being struck off the register
- Directors being personally prosecuted
- Damage to business reputation (visible on public records)
- Difficulty securing loans or investment
In extreme cases, directors can be disqualified from running a company.
Top Tips: How Can You Avoid Late Filing Penalties?
The only guaranteed way to avoid a penalty is to file on time. That said, you can:
- Keep accurate records year-round
- Mark deadlines in multiple places (calendars, reminders, apps)
- File well before the deadline – don’t wait until the last day
- Double-check your registered office address for penalty notices
- Work with a professional accountant
What If Your Accounts Are Incorrect?
Submitting inaccurate accounts can also cause problems. If Companies House rejects them as incomplete or wrong, you’ll still be penalised if the corrected version is submitted late.
How Will You Know If a Penalty Has Been Imposed?
Companies House will send a penalty notice to your registered office address. If you’ve moved and not updated your address, you might miss it so always keep your company records up to date.
Final Thoughts
Companies House late filing penalties are strict and they’re not going away. The system is designed to push businesses towards timely, transparent filing.
The good news? With a bit of organisation and the right support, these penalties are entirely avoidable and you’ll never have to pay one.
