What is a CIO charity?

A Charitable Incorporated Organisation is a charity structure that has its own legal identity but is regulated only by the Charity Commission, not by Companies House. It combines the limited liability of a company with the simpler, single-regulator life of a charity. It must register with the Commission at any income level because it does not exist in law until it is registered.

What is the difference between a CIO and a charitable trust?

The key difference is legal identity and liability. A CIO is incorporated, so the charity itself holds contracts and property and trustees are generally protected from personal liability. A charitable trust is unincorporated, so the trustees personally hold contracts and property and can be personally liable. A trust is simpler for a small grant-making or asset-holding charity with no staff or premises.

Can you convert a charitable trust to a CIO?

You cannot simply reclassify a trust as a CIO. In practice you set up a new CIO and transfer the activities, assets and staff of the trust into it, then wind up the old trust. It is a manageable process but it needs care with contracts, permissions and any restricted funds, so plan it rather than rush it.

CIO vs Charitable Trust: Which Structure Fits You?

A plain comparison of the Charitable Incorporated Organisation and the charitable trust: liability, reporting, how each is run, and which structure fits a charity that employs people, holds property or signs contracts.

Choosing a legal structure is one of the few charity decisions that is genuinely hard to reverse later. Get it right and you rarely think about it again. Get it wrong and you discover the problem at the worst moment, usually when the charity is about to sign a lease, hire its first employee, or take on a contract, and the trustees realise they are personally exposed. This guide compares the two structures small charities most often weigh: the Charitable Incorporated Organisation and the charitable trust.

The one distinction that matters most

Before any detail, understand the single difference that drives everything else: incorporation. An incorporated charity has its own legal identity, separate from the people who run it. An unincorporated charity does not, so it can only act through its trustees as individuals.

A Charitable Incorporated Organisation is incorporated. A charitable trust is not. That is the fork in the road. Almost every practical difference between the two, from liability to how you sign a contract, flows from this one point.

What a charitable trust is

A charitable trust is one of the oldest and simplest charity structures. A small group of trustees agree, through a trust deed, to hold and apply assets for a charitable purpose. There is no separate legal person: the trust is essentially the trustees acting together under the deed.

That simplicity suits a particular kind of charity:

Grant-making bodies that receive money and give it out, without staff or premises.
Charities set up to hold a specific asset, such as an endowment or a piece of land, for a defined purpose.
Small, stable organisations run entirely by volunteers with low risk and few external contracts.

The trade-off is exposure. Because the trust has no legal identity, the trustees personally enter into any contract, personally employ any staff, and can be personally liable if things go wrong. For a charity that never signs anything significant, that risk is largely theoretical. For one that does, it is real.

What a CIO is

The Charitable Incorporated Organisation was created to give charities the protection of incorporation without the burden of dual regulation. Before the CIO, a charity that wanted limited liability usually became a charitable company, which meant answering to both the Charity Commission and Companies House. The CIO answers only to the Commission.

A CIO gives you three things a trust cannot:

Its own legal identity, so the charity, not the trustees, holds property and signs contracts.
Limited liability, so trustees acting properly are protected from personal liability for the charity debts.
A single regulator, avoiding the extra filings and duties that come with Companies House.

The price is a little more formality than a trust. A CIO must register with the Commission at any income level, keep proper records, and follow its constitution. For most charities that plan to employ people or grow, that formality is a small cost for the protection it buys.

The question is not which structure is better in the abstract. It is whether your charity will ever sign a contract, hire staff or hold property. If the answer is yes, incorporation stops being optional.

A side-by-side comparison

Liability

In a CIO, trustees who act honestly and within their powers are generally protected from personal liability. In a trust, trustees can be personally liable for the charity obligations. This is the decisive difference for any charity that takes on staff, premises or contracts.

Registration and reporting

A CIO must register with the Commission from the outset, whatever its income. A charitable trust only has to register once its income exceeds £5,000. Both must report annually once registered, with the detail of reporting rising with income for either structure.

How each is run

A trust is usually run by a small, self-appointing group of trustees under the trust deed, which suits a closed, stable body. A CIO can use either a foundation model, with trustees as the only members, or an association model, with a wider membership that appoints the trustees. The association model suits charities that want members or a democratic element.

Cost and effort

A trust is marginally cheaper and simpler to set up and run, with no incorporation and the lightest reporting at low income. A CIO involves slightly more setup and ongoing formality. In practice the difference in effort is modest, and it is rarely the deciding factor.

So which should you choose?

The honest answer for most new charities today is the CIO. It has become the default because the protection of incorporation matters to almost any organisation that intends to do more than hold and distribute money, and the CIO delivers that protection without the dual regulation that made the charitable company burdensome.

Choose a charitable trust when all of the following are true:

The charity will not employ staff.
It will not hold property or sign significant contracts.
It is a small, low-risk, volunteer-run body, often grant-making or asset-holding.
The trustees value simplicity over the protection of limited liability.

Choose a CIO when any of the following are true:

You will, or might, employ people.
You will hold property or enter contracts of any size.
You expect the charity to grow and take on more risk over time.
The trustees want protection from personal liability, which is most trustees once they understand the exposure.

If you already have the wrong structure

Charities regularly outgrow a trust. If yours has, you are not stuck, but you cannot simply relabel it. The route is to establish a new CIO and transfer the activities, assets, staff and contracts across, then close the old trust. It takes care, particularly with restricted funds and existing agreements, but it is a well-trodden path. The mistake is to keep operating an exposed structure because changing it feels like effort. The effort of converting is always smaller than the cost of the liability you are carrying in the meantime.
