The first 30 days after incorporating a limited company

What a new director should organise immediately after Companies House registers the company.

Last reviewed: 27 July 2026Review due: 6 April 2027

Overview

Incorporation creates the company, but it does not complete the operational setup. Directors should secure the statutory records, open appropriate banking and bookkeeping arrangements, record share ownership, confirm the registered office and registered email, and decide when the company will start trading. Once trading begins, HMRC must be told and the company needs a reliable record-keeping process.

Who this applies to

New UK limited companies and overseas founders who have recently incorporated a UK company.

Key points

  • Keep the incorporation certificate, memorandum, articles and share records together.
  • Use a separate business bank account and avoid mixing personal and company transactions.
  • Record director loans, share capital and startup costs correctly.
  • Set up access to Companies House and HMRC services and protect authentication details.

Important dates and deadlines

Companies House sets the accounting reference date and first accounts deadline. HMRC should be told when the company becomes active for Corporation Tax. PAYE and VAT registrations may be needed before payroll begins or when VAT registration conditions are met.

Practical checklist

  1. Confirm registered office and registered email.
  2. Create statutory registers and issue share certificates where appropriate.
  3. Open bookkeeping and bank feeds.
  4. Record the trading start date.
  5. Review VAT, PAYE, pension and insurance requirements.

Frequently asked questions

Does incorporation automatically register the company for Corporation Tax?

No. HMRC must be told when the company starts business activity.

Can the company pay costs incurred before incorporation?

Some pre-trading costs may be allowable, but the invoices, dates and business purpose should be reviewed.
