How to Appeal a Late Company Accounts Filing Penalty Successfully

Missed the deadline for filing your company accounts? You're not alone—and you might also be facing a late filing penalty from Companies House. The good news? If you have a valid excuse, you may be able to appeal the penalty and get it removed.

In this guide, we’ll walk you through the step-by-step process to appeal a penalty for late filing in the UK, along with tips and examples to help you make a strong case.

Why Do You Get a Late Filing Penalty?

Every company must submit annual accounts to Companies House by a certain deadline. If you miss it, you’ll face an automatic fine, starting from £150 and going up depending on how late you are. If you file late two years in a row, the fine doubles.

Here’s a quick breakdown of the penalty amounts:

• 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

Appealing a penalty doesn’t always work—but if you have a strong reason, it’s worth trying.

Step-by-Step Guide to Appeal a Late Filing Penalty

Let’s break things down into manageable steps. Follow these to make sure your appeal has the best chance of success.

Step 1: Understand What Counts as a "Valid Reason"

Companies House doesn’t accept just any excuse. You must show that you had an exceptional circumstance that caused the delay. That means something serious and unexpected, not everyday issues.

Acceptable reasons may include:

• Serious illness (especially if it affects the person responsible for filing)
• Unexpected death of a close colleague or company secretary
• Fire, flood, or natural disaster that disrupted your ability to submit accounts
• System or software failure on the Companies House side
• Strike of extreme weather impacting postal delivery or internet services

Invalid reasons include:

• You forgot or weren’t aware of the deadline
• Your accountant was on holiday
• Accounts were sent to HMRC (not Companies House)
• Delays caused by cash flow issues

Step 2: Gather Supporting Evidence

This is key. To be taken seriously, don’t just explain the situation—prove it.

Depending on your reason, include any of the following:

• Hospital records or doctor’s notes
• Death certificate (if applicable)
• Photos or insurance documents for disasters like floods or fires
• Screenshots of error messages if Companies House systems were down

Think of it this way: If someone who doesn’t know you read your appeal, would they believe this really happened?

Step 3: Submit Your Appeal Online or by Post

There are two ways to send in your appeal:

• Online: Use the official online appeals form on the GOV.UK website.
• Post: Send a letter (make sure it’s clear and well-organized) to Companies House. Include your company number, penalty reference, and all evidence.

Important: You must appeal within 14 days from the date the penalty was issued. Don’t wait!

Step 4: Wait for a Decision

Once you submit your appeal, Companies House will review your case. This can take a few weeks. If they accept your appeal, the penalty will be cancelled.

If they reject it, they’ll explain why. You might still have the option to review the decision or take it further to a Tribunal.

Top Tips to Make Your Appeal Strong

Want to increase your chances of success? Here are some extra pointers:

• Be honest. Don’t exaggerate or make up an excuse—it won’t work.
• Keep it short and to the point. Avoid long-winded explanations.
• Use clear language. Imagine explaining your story to a friend.
• Double-check your evidence. Attach only what proves your case.
• Follow up if needed. If you haven’t heard back after several weeks, it’s okay to check in.

What If My Appeal Fails?

If Companies House rejects your appeal, you can:

• Ask for a review. You may be able to request a second look, especially if you have new evidence.
• Appeal to the First-tier Tribunal. This is a last-resort option and should only be used if you strongly disagree with Companies House’s decision.
• Pay the penalty. Sometimes, it’s less hassle to just pay and make sure it doesn’t happen again next year.

Final Thoughts

Filing your company accounts late is never ideal—but mistakes happen. If you genuinely had a valid reason for missing the deadline, and you can prove it, don’t hesitate to appeal your penalty.

Plan ahead next time: use calendar reminders, communicate with your accountant early, and know your filing deadlines. After all, prevention is easier than appealing a penalty later.
