Comprehensive guide to what happens after a company is incorporated in the UK. Covers post‑incorporation steps including statutory filings with Companies House, tax registration with HMRC, reporting deadlines, director duties, and practical compliance actions for new limited companies.

Incorporation is the legal process that creates a company as a separate legal entity under UK law. Once a company is incorporated with Companies House in England and Wales, its existence begins legally and publicly, but this is just the start of its statutory obligations, tax responsibilities, and governance duties. Understanding what happens next is essential for company directors, owners, solicitors, and anyone planning to operate a limited company. This article explains the post‑incorporation process, statutory compliance duties, tax registration, reporting requirements, administrative obligations, and practical steps to keep your company legally compliant and ready to trade.
1. Confirmation of Incorporation
As soon as Companies House approves the incorporation application, the company is legally formed. You will receive:
- A Certificate of Incorporation, which states the company's name, registration number, and date of incorporation.
- Official copies of the memorandum and articles of association submitted during registration.
- A public record entry that includes directors, share capital, registered office, and initial members.
- An authentication code for web filing to submit future statutory documents.
The Certificate of Incorporation is often required to open a business bank account, apply for finance, or conclude contracts in the company's name.
2. Verification and Record‑Keeping
Although the company now legally exists, directors should verify all registration details held by Companies House immediately after incorporation. Errors in the registered office, directors' details or share structure can cause problems with bank accounts, tax registrations, contracts, or official correspondence.
Directors must also ensure that statutory company records are properly maintained, either at the registered office or at an alternative inspection location. These records include:
- Register of directors
- Register of members
- Register of people with significant control (PSCs)
- Register of shareholders and share capital details
- Minutes of board and general meetings
Under recent reforms, some statutory registers may be held centrally by Companies House, but accurate records remain essential for legal compliance.
3. Registering for Corporation Tax
Every limited company must register with HM Revenue & Customs (HMRC) for Corporation Tax within three months of starting to trade. Trading includes buying or selling goods or services, advertising, renting property, or employing staff; it is not limited to profitable activity.
On incorporation, Companies House may notify HMRC, and HMRC will subsequently issue a Unique Tax Reference (UTR) to the company's registered office within about 14 days. Directors should keep this UTR secure and use it when communicating with HMRC.
Even if the company does not trade immediately, it must still notify HMRC if it remains dormant for tax purposes, which may influence whether Corporation Tax returns and payments are required.
4. Opening a Business Bank Account
While not a statutory requirement, it is practical to open a dedicated business bank account once the company is incorporated. A company bank account helps manage finances, receipts, and expenses in the company's name, separates business and personal funds, and is often required for tax and credit transactions.
Most banks will require the Certificate of Incorporation, company registration number, and proof of director identity to open an account, and some will request copies of the articles of association.
5. Statutory Reporting to Companies House
Annual Accounts
After incorporation, the company must prepare and file annual accounts:
- First accounts are due 21 months after incorporation.
- For subsequent years, accounts are due 9 months after the company's accounting reference date (ARD), which is typically the anniversary of incorporation.
Annual accounts summarise the company's financial position and activities. Failure to file accounts on time can result in financial penalties and legal consequences for directors.
Confirmation Statement
Every company must file a confirmation statement at least once a year to confirm that the information held by Companies House is accurate and up to date. The confirmation statement includes details about directors, registered office address, PSCs, share capital and SIC codes.
Recent legal changes require companies to include a statement confirming that the company's intended future activities are lawful at confirmation statement filing.
6. Reporting Changes to Company Details
Once incorporated, a company must notify Companies House of specified changes within statutory deadlines, including:
- Changes to directors or company secretaries and their personal details
- Appointments or removals of officers
- Changes to PSCs or their particulars
- Changes to the registered office address or registered email
- Changes in share capital or authorisation
- Changes to the articles of association
For example, a change to the registered office must be communicated promptly to ensure correspondence reaches the company and remains legally valid.
Where articles are amended after incorporation, the special resolution and the updated articles must be filed with Companies House within 15 days to avoid potential offences.
7. Director Responsibilities and Governance
Directors assume legal duties under the Companies Act 2006 once the company is incorporated. These duties include:
- Acting within powers conferred by the company's constitution
- Promoting the success of the company
- Exercising independent judgement
- Avoiding conflicts of interest
- Ensuring compliance with statutory reporting and tax obligations
Failing to meet statutory duties can result in fines, personal liability for company debts, or disqualification from serving as a director.
8. Taxation and HMRC Obligations
In addition to Corporation Tax registration, directors should consider other tax obligations:
- Payroll and PAYE: If the company employs staff, it must operate PAYE and submit payroll reports to HMRC.
- VAT registration: Mandatory when annual taxable turnover exceeds the current threshold (e.g., £85,000).
- Filing Company Tax Returns (CT600) annually, reporting taxable profits and calculating tax due.
9. Practical Considerations and Best Practices
Insurance
Directors should consider whether their company needs business insurance such as:
- Employers' liability insurance (mandatory if the company has employees)
- Public liability insurance for interactions with clients or the public
- Professional indemnity insurance for errors or omissions in services provided
Accountant or Adviser Engagement
Appointing an accountant or corporate adviser can help ensure compliance with tax filings, statutory reporting and financial record‑keeping. Professional support can reduce the risk of penalties or director liability through administrative errors.
Summary
Once a company is incorporated in England and Wales, it becomes a legal entity with statutory obligations and ongoing responsibilities. Directors must verify company details, maintain accurate records, register for Corporation Tax, open a business bank account, file annual accounts and confirmation statements, and notify Companies House of key changes. In addition, they must comply with tax and employment obligations as appropriate and fulfil statutory duties under the Companies Act 2006. Understanding and acting on these post‑incorporation requirements helps protect the company, its directors, and its stakeholders from legal risks and ensures lawful corporate governance.
