Direct answer
After registering a limited company, your first job is to organise the company records, understand your director responsibilities, prepare for annual accounts, Company Tax Returns, Corporation Tax and confirmation statements, and keep evidence for business income and costs.
After registering a limited company, you need to keep company records, understand Companies House and HMRC deadlines, set up sensible record-keeping, and know when to ask an accountant or tax adviser.
Set up the company admin basics
Save your certificate of incorporation, company number, authentication code, articles of association and shareholder details somewhere you can find them quickly.
Check that the registered office, directors, people with significant control and share information are correct, because these details feed future Companies House filings.
Understand the first deadlines
A private limited company's first accounts are usually due at Companies House 21 months after registration. Later annual accounts are usually due 9 months after the financial year ends.
Corporation Tax is usually due 9 months and 1 day after the accounting period ends, while the Company Tax Return is due 12 months after the accounting period ends.
Keep records from day one
Keep invoices, receipts, bank records, payroll records if you employ people, VAT records if registered, and evidence for business expenses.
Business Sorted can help you turn these obligations into plain-English tasks, but it does not replace professional advice.
Practical checklist
- - Save incorporation documents and Companies House authentication details.
- - Add the first accounts, Company Tax Return, Corporation Tax and confirmation statement dates to a deadline tracker.
- - Set up a separate business bank account or a clear record-keeping process.
- - Decide whether you need an accountant, payroll, VAT registration or professional insurance.
- - Keep source links to official GOV.UK guidance beside each deadline.
Common mistakes
- - Assuming Companies House and HMRC deadlines are the same.
- - Waiting until the first year end before organising records.
- - Thinking an accountant removes the director's legal responsibility.
- - Losing the Companies House authentication code.
FAQs
Do I need to file anything immediately after incorporation?
Not always, but you should organise your records and future deadlines immediately so the first accounts, tax and confirmation statement tasks do not arrive as a surprise.
Can Business Sorted tell me my exact dates?
Business Sorted is designed to help you organise deadline reminders from your business details and official source links. You should still check official records and professional advice where needed.
