UK Business Compliance Checklist: Everything You Need to Know

Image for UK Business Compliance Checklist: Everything You Need to Know post
Running a business in the UK involves more than just registering your company — staying compliant with government regulations is critical to avoiding penalties, maintaining credibility, and ensuring long-term success. Whether you’re a new startup or a growing business, this UK business compliance checklist will help you stay on top of your legal obligations.

1. Annual Confirmation Statement

All UK companies must submit a Confirmation Statement (CS01) to Companies House at least once every 12 months. This keeps your company details, such as directors, registered address, and share structure, up to date.
  • Due: Every 12 months from your company’s incorporation date.
  • Fee: £13 (online) or £40 (paper)

2. Annual Accounts Filing

Your business must prepare and file statutory annual accounts with Companies House. These must reflect your company’s financial position and meet accounting standards.
  • Due: 9 months after your company’s accounting year ends
  • Who Prepares It: Your accountant or accounting service

3. Corporation Tax Returns

Every active UK company must file a Corporation Tax Return (CT600) with HMRC. This shows your income, expenses, and the tax due.
  • Register within 3 months of starting trading
  • Submit return: 12 months after your accounting period ends
  • Pay tax: Within 9 months and 1 day of your year-end

4. VAT Registration and Returns

If your taxable turnover exceeds £85,000 in a 12-month period, VAT registration with HMRC is mandatory. Once registered, you must file regular VAT returns — typically quarterly.

5. PAYE & Employee Obligations

If you employ staff, you must register for PAYE (Pay As You Earn) and deduct tax and National Insurance from employee salaries.
Your obligations include:
  • Issuing payslips
  • Reporting payroll to HMRC
  • Providing P60s annually

6. Maintain Statutory Records

Every UK company must maintain accurate statutory registers, including:
  • Register of directors and secretaries
  • Register of shareholders
  • Register of persons with significant control (PSC)

These must be kept up to date and made available for inspection at your registered office.

7. Data Protection Compliance (UK GDPR)

If you handle customer or employee data, you must comply with the UK GDPR and register with the Information Commissioner’s Office (ICO), if required.

8. Business Insurance Requirements

While not all types of insurance are mandatory, Employers’ Liability Insurance is legally required if you have staff. Other types (like public liability or professional indemnity) may be recommended based on your business type.

9. Industry-Specific Licences or Permits

Depending on your business activity, you may require industry-specific licenses (e.g. for food handling, financial services, or import/export). Use the UK government’s licence finder tool to check:

10. Stay Up to Date with Regulatory Changes

Laws and thresholds can change each tax year. As we move into 2025, businesses should review any updates from HMRC or Companies House to remain fully compliant.
