Why Compliance Matters for Limited Companies

Running a limited company comes with a range of statutory obligations that go well beyond simply filing a tax return. Directors have legal duties under the Companies Act 2006, and failing to meet deadlines can result in automatic financial penalties, director disqualification, or in serious cases, criminal liability. The good news is that staying compliant is very manageable with a clear annual schedule.

Your Annual Compliance Calendar

1. Confirmation Statement (formerly Annual Return)

Every company must file a Confirmation Statement with Companies House at least once every 12 months. This confirms that key information on the Companies House register — directors, registered office, share structure, SIC codes — is accurate and up to date. The filing fee is £34 online. Missing this deadline results in an automatic strike-off warning.

2. Annual Accounts (Statutory Accounts)

Private limited companies must file their annual accounts with Companies House within 9 months of the company's financial year end. Small companies may file abbreviated accounts. Late filing attracts automatic penalties starting at £150 and rising steeply the longer the delay continues.

3. Corporation Tax Return (CT600)

You must file a Company Tax Return with HMRC within 12 months of your accounting period end. Corporation Tax itself is due within 9 months and one day of the period end. These are two separate deadlines that are easy to confuse.

4. VAT Returns (if VAT registered)

VAT-registered businesses typically file returns quarterly, with payment due one calendar month and seven days after the end of each VAT period. Late submissions and payments incur a points-based penalty system introduced in 2023.

5. PAYE and Payroll

If you operate a payroll (even for a single director/employee), you must submit Full Payment Submissions (FPS) to HMRC on or before each payday. An Employer Payment Summary (EPS) may also be required. Annual tasks include issuing P60s to employees by 31 May and reporting benefits in kind via P11D forms by 6 July.

Ongoing Compliance Obligations

  • Person of Significant Control (PSC) register: Keep your internal PSC register up to date and report changes to Companies House within 14 days.
  • Director changes: Notify Companies House within 14 days of appointing or removing a director.
  • Registered office changes: Update Companies House promptly — all official correspondence will go to the registered address.
  • Share allotments and transfers: File the relevant forms (SH01, J30 stock transfer form) with Companies House as required.
  • GDPR / data protection: If you process personal data, ensure you're registered with the ICO (if required) and your privacy policies are current.

Director Duties Under the Companies Act 2006

Beyond filing obligations, directors must actively uphold their statutory duties:

  1. Act within the company's constitution and powers.
  2. Promote the success of the company for the benefit of its members.
  3. Exercise independent judgement.
  4. Exercise reasonable care, skill, and diligence.
  5. Avoid conflicts of interest.
  6. Not accept benefits from third parties.
  7. Declare any interest in a proposed transaction or arrangement.

Practical Tips to Stay Compliant

  • Diarise all deadlines at the start of your financial year — don't rely on HMRC or Companies House to remind you.
  • Work with a qualified accountant who manages filing deadlines on your behalf.
  • Use accounting software that integrates with HMRC's Making Tax Digital requirements.
  • Keep a central compliance log updated whenever you make changes to company structure or personnel.

Compliance is not optional — but it doesn't have to be overwhelming. A methodical approach and the right professional support will ensure your company remains in good standing year after year.
