How to set up a CIO, step by step

A charitable incorporated organisation (CIO) is a charity that can employ, own property and sign contracts in its own name, without registering at Companies House. It only comes into existence when the Charity Commission registers it, whatever its income.

8. Initial checkThe Commission checks completeness and trustee eligibilityWithin 48 hours
9. DecisionRegistered, registered with conditions, returned or rejectedNormally 40 working days, if the four conditions below are met
10. On the registerThe CIO exists from registration; the entry goes publicShould appear within 48 hours of you being told
11. Bank and HMRCOpen an account; apply to HMRC for Gift Aid; set up Charities OnlineCharities Online activation code: around a week; use it within 28 days
12. First year endAnnual return, accounts and trustees' reportWithin 10 months of the financial year end

The 40 working days applies when you use the Commission's example objects and model constitution, your activities match your objects, and any private benefit is incidental and properly managed. Others take longer.

1. Purposes

Each purpose must be charitable and for the public benefit. Start from the Commission's example objects if one fits. Writing purposes.

2. Foundation or association

Foundation: the trustees are the only voting members. Association: a wider membership votes, usually electing trustees at an AGM. The two models compared.

3. Name

4. Trustees

The model guidance says a CIO should have at least three trustees and suggests no more than 12. Individual trustees must be 16 or over and not disqualified. The models assume a board of individuals. How many trustees.

5. The constitution

6. The trustee declaration

Printed, signed in ink by every trustee, scanned as a PDF. The Commission can't accept electronic signatures. How to fill it in.

7. The application

You don't need to prove income: the £5,000 test doesn't apply to CIOs. You do explain how the CIO will be funded. You do explain how the CIO will be funded. You do need public contact details, the constitution PDF, every trustee's details, and explanations of your activities and public benefit. Bank details are asked for if you already have an account. The questions explained.

8 to 10. The decision

If the application is unclear or incomplete, it's returned for you to resubmit. If registered, your charity number is emailed to the main contact, and each trustee with an email address gets a list of guidance.

11. After registration

12. Every year

A CIO sends an annual return, accounts and a trustees' annual report to the Commission every year, whatever its income, within 10 months of its year end. For years ending on or after 30 September 2026: under £500,000 income it can prepare simpler receipts and payments accounts; over £40,000 the accounts need independent examination, unless an audit is required, with a professionally qualified examiner over £500,000. A CIO isn't fined for late filing, but some breaches of the CIO regulations are offences.
