Companies limited by shares and companies limited by guarantee are different corporate structures. The decision should follow the purpose of the organisation, its funding and the rights intended for its members. A guarantee company is not automatically a charity or exempt from tax.
A company limited by shares
This structure has shareholders and share capital. Shares carry rights determined by their class and the company documents. It is commonly considered where owners want an equity interest, investment or the possibility of dividends from distributable profits. [1][2]
Before choosing it, decide how ownership will be divided and whether future investors need a particular class or set of protections. Do not confuse an initial nominal share value with the commercial value of the organisation.
A company limited by guarantee
A guarantee company has guarantors rather than share capital in the usual form. Their undertaking to contribute a specified amount if the company is wound up is recorded in the formation arrangements. The membership and governance provisions need to fit the organisation's purpose. [2][3]
This form is often considered for membership or non-profit activities. However, the label alone does not establish charitable status, regulatory approval, grant eligibility or tax treatment. Those questions require separate assessment.
Focus on how decisions and money will work
Ask who can become a member, how members vote, how directors are appointed and what happens when someone leaves. Then consider where funding will come from: subscriptions, trading income, grants, donations or investment.
For illustration, a community association seeking member participation may have different objectives from a consultancy expecting outside equity investment. Copying the structure of a familiar organisation can be misleading if its funding and governance are different.
Prepare a structure comparison
- The organisation's principal activities and intended beneficiaries.
- Whether owners expect returns on an equity investment.
- Who should control membership and board appointments.
- Restrictions required by a funder or regulator.
- Plans for assets if the organisation eventually closes.
Avoid assuming a tax result from the name
Both the legal structure and actual activities matter. Discuss tax registrations, accounting and any proposed charitable or community-interest status before launching. The incorporation application creates the selected company; it does not resolve every legal or financial question about how that company will operate.
Map the funding before choosing the legal form
List the money the organisation expects to receive in its first two years. Separate customer payments, member subscriptions, donations, grants and funds provided in return for ownership. Then write down what each contributor expects back. Someone buying shares for a financial return has a different relationship from a member paying an annual subscription to support activities.
If a prospective funder has conditions, obtain the actual conditions before incorporation. Do they require a particular structure, limits on distributions, specific purposes or a separate regulatory status? Avoid relying on a general statement that a company limited by guarantee is always eligible for community funding. Eligibility belongs to the particular funding scheme.
Compare two illustrative projects
A group of consultants wants to share ownership, retain profits for expansion and potentially sell part of the business to an investor. Their planning should address shares, investment rights and exits. A company limited by shares may be a structure to investigate, while the tax and governance details still need separate work.
A local membership project wants members to elect a board and use subscriptions to provide community activities. Its planning may instead focus on membership admission, voting, member departure and how assets should be used if the project closes. A guarantee company could be considered, but the founders must still decide whether they need charitable or other status and which regulator's rules would apply.
Neither example determines the answer for every consultancy or community project. The comparison shows why the expected relationship between contributors, members and the organisation matters more than copying a familiar organisation's label.
Write the membership rules in practical terms
For a guarantee company, ask who can apply to become a member, who accepts applications and how membership ends. Decide whether people using the organisation's services will also be members. A service user and a voting member need not be treated as the same concept without considering the consequences.
Explain the guarantee obligation accurately to prospective members. It is different from a monthly subscription or a director's own responsibilities. Keep the agreed guarantee and membership arrangements with the formation records so the organisation can explain what was actually accepted. [2][3]
Check whether the structure supports future change
Discuss the realistic next stage before selecting the form. A project might plan to employ staff, purchase premises, merge with another organisation or attract a different type of funding. Ask whether the proposed constitution accommodates those plans and what approvals would be needed.
If the founders remain divided between a commercial investment model and a membership model, resolve that purpose first. A registration form cannot settle competing expectations about who should benefit financially or control decisions. A written structure brief should show the agreed purpose, funding assumptions and outstanding specialist questions before anyone files the application.
A written structure review can record why the chosen form fits the project and which additional registrations or documents are needed next.

Frequently asked questions
Is every company limited by guarantee a charity?
No. Charity registration, charitable purposes and relevant tax treatment are separate matters.
Can a guarantee company use the same articles as a shares company?
Use rules suited to the correct company type. Their membership and capital arrangements differ.
Is a guarantee company automatically a charity?
No. Incorporation in that form does not by itself confer charitable status, tax relief or grant eligibility. Assess the organisation purpose, constitution, activities and relevant regulator requirements separately before using a charitable description in fundraising or customer communications.
Can members of a guarantee company also be directors?
The roles can overlap, but membership and management are different responsibilities. Check the proposed constitution and appointment rules, and explain to each person which role they hold. A membership subscription does not itself establish a director appointment.
