UK Companies House Deadlines Every Director Must Know: A 2024 Compliance Calendar

The Cost of Missing a Companies House Deadline

In the UK, every limited company director has a legal duty to file timely returns and accounts with Companies House. Missing a single deadline can trigger automatic penalties, director disqualification warnings, and reputational damage that affects credit ratings and investor confidence. This guide walks you through every major filing requirement, penalty structure, and practical strategy to stay compliant—whether you run a startup or a multi-director enterprise.

The core principle: Companies House operates on strict statutory deadlines. Unlike tax authorities, which may grant extensions in hardship cases, Companies House penalties are near-automatic once a return is late.

Annual Return (Confirmation Statement) Deadline

Every UK company must file a Confirmation Statement (formerly the Annual Return) once every 12 months. This is separate from your corporation tax return to HMRC.

Key Facts

• Filing window: You have 14 days after your company's anniversary of incorporation (or accounting reference date change) to file.
• Key information required: Directors' names and addresses, registered office address, statement of capital, shareholders' details (if required), and confirmation that all information is accurate.
• Online filing: File via the Companies House online portal using your authentication code.
• Penalty for lateness: £150 (first month overdue); £375 (after 3 months); £1,000 (after 12 months).

We strongly recommend filing within 7 days of your anniversary to create a safety buffer. Many directors use calendar alerts or engage their accountant to handle this as a routine task.

Accounts Filing Deadlines

Unless your company qualifies as dormant, you must file full or abbreviated accounts (depending on size) within 9 months of your year-end.

Statutory Filing Requirements by Company Size

Small companies (turnover under £10.2m, assets under £5.1m, or fewer than 50 employees) may file abbreviated accounts, which are less detailed.

Larger companies and all public companies must file full accounts with detailed notes, directors' report, and strategic business review.

• Accounts must show a true and fair view of the company's financial position.
• Directors must sign a statement confirming they are aware of their obligations and that the accounts have been properly prepared.
• Auditor's report is required unless the company is small and/or revenue-exempt.

Penalties and Consequences

• Up to 3 months late: £150 penalty.
• 3–12 months late: £375 penalty.
• Over 12 months late: £1,000 penalty + potential director disqualification proceedings.

Read the Companies House guidance on accounts filing for detailed requirements.

Director and Secretary Changes

Any change to your board must be notified to Companies House within 14 days.

• New director or secretary: File form AP01.
• Director resignation or removal: File form TM01.
• Change of director details (address, name): File form CH01.
• Change of company secretary: File form AP03.

Missing this deadline can result in a £150 penalty per month and may invalidate board decisions made during the interim period.

Registered Office and Address Changes

If your company moves premises, you must notify Companies House via form AD01 within 14 days. This is a critical compliance point because:

• Official correspondence is served at your registered office.
• HMRC and other authorities rely on this address for statutory notices.
• Filing the wrong address may mean you miss penalty notices, leading to escalated enforcement action.

Charges and Mortgage Documents

If your company takes a loan secured against assets (a charge), you must file the charge document with Companies House within 21 days of creation.

• File form MR01 (charge) or form MR06 (satisfaction of charge when the debt is repaid).
• Failure to register within 21 days means the charge becomes void and loses priority—a major issue if the company later enters insolvency.

Share Capital Changes

Changes to issued share capital (allotment of new shares, capital reduction, share subdivision) must be notified within statutory deadlines:

• Allotment of shares: File form SH01 within 1 month of allotment.
• Share capital reduction: File a court order or written consent form within 1 month of court approval or shareholder consent.

Delaying share allotment notification can create liability issues for directors and complicate future fundraising or investor updates.

Disqualification and Strike-Off Risk

Director Disqualification

If a company fails to file accounts for 18 months or more, or accumulates serious late filings, the Secretary of State may begin disqualification proceedings against its directors under the Company Directors Disqualification Act 1986. Disqualified directors face:

• Ban from acting as a director for 2–15 years.
• Personal liability for company debts incurred while acting in breach of the disqualification order.
• Reputational and credit damage.

Strike-Off

If your company has failed to file for 3+ months, Companies House may issue a strike-off notice. If you do not respond within 2 months, the company is dissolved. This is problematic if:

• You still have assets or liabilities.
• You plan to trade again.
• You owe tax to HMRC.

Reapplication costs £40 + professional fees to restore the company to the register.

Practical Compliance Checklist

Use this checklist to audit your company's filing status:

• [ ] Confirmation Statement: Due date clearly marked in your calendar; filed 7–10 days before the deadline.
• [ ] Accounts: Prepared by your accountant; filed within 9 months of year-end; directors have signed them.
• [ ] Director changes: Any new appointments, resignations, or address changes filed within 14 days.
• [ ] Registered office: Updated immediately if you move premises.
• [ ] Charges/loans: Mortgage or charge documents filed within 21 days of creation.
• [ ] Share allotments: SH01 forms filed within 1 month of any new share issuance.
• [ ] Annual accounting reference date review: Confirm the company's year-end is still appropriate and file AD02 if you need to change it.

Why Engage a Qualified Accountant

While you can file directly, delegating to a qualified accountant or tax advisor:

• Reduces human error: Professional filers use secure portals and double-check before submission.
• Ensures timeliness: Regular firms build filing into their client calendar and send reminders.
• Protects your director status: An accountant reviews the accounts for accuracy before filing, reducing the risk of regulatory scrutiny.
• Saves time: Directors can focus on running the business rather than administrative compliance.

Every filing with Next Tax Source is reviewed and signed off by a licensed UK chartered accountant before submission to Companies House. This gives you peace of mind and a clear audit trail.

Taking Action Now

If your company is compliant: Set calendar reminders for each deadline and review this checklist quarterly.

If you have missed a deadline: Contact Companies House immediately. Many late filings can be accepted if submitted before a second-round penalty notice is issued. Companies House also operates a 'late filing penalty relief' scheme in genuine hardship cases.

If you're unsure of your filing status: Request a company report from the Companies House website or ask your accountant to audit your compliance status.

Frequently asked questions

What happens if I miss a Companies House deadline by one day?

A penalty is triggered immediately. For most filings (Confirmation Statement, accounts, director changes), the first-stage penalty is £150 if filed within one month of the deadline. After three months, it rises to £375, and after 12 months, to £1,000. There is no grace period.

Can I file my company accounts late if I have a good reason?

Companies House does not grant routine extensions. However, if you have experienced genuine hardship (e.g., serious illness, bereavement), you may apply for relief from penalty after the fact. The decision is discretionary, and relief is not guaranteed. Prevention through early filing is far safer.

Do I need to file accounts if my company is dormant?

Dormant companies may file a short exemption form instead of full accounts in some years, but they must still file a Confirmation Statement annually and notify Companies House of dormant status. Confirm your eligibility with your accountant, as the rules are strict.

What is the difference between a Companies House filing and a corporation tax return?

Companies House filings (accounts, Confirmation Statement, director changes) are regulatory filings that maintain your company's public record. A corporation tax return is filed with HMRC (the UK tax authority) and determines your tax liability. Both are mandatory and have different deadlines.

Can a director be disqualified for just one missed filing?

No single missed filing automatically triggers disqualification. However, persistent non-compliance (e.g., 18+ months without filed accounts) or multiple late filings can prompt the Secretary of State to investigate and launch disqualification proceedings. Prevention is far easier than cure.
