Corporation Tax And Mutuality
Members’ clubs are subject to corporation tax legislation and may be required to submit an annual corporation tax return to HM Revenue & Customs (HMRC).
Fortunately, members’ clubs that satisfy the long-established principle of mutuality benefit from favourable tax treatment. It is a fundamental principle of taxation that a person cannot make a taxable profit from trading with themselves. Accordingly, where a club is owned by its members and exists to provide facilities for their benefit, any surplus arising from transactions with members is not subject to corporation tax.
Under the doctrine of mutuality, trading surpluses derived from transactions with a class of members are exempt from tax. This principle applies whether the club is unincorporated, limited by guarantee or constituted as a registered society.
Where mutuality applies:
In these circumstances, subscriptions and any surplus or deficit arising from the ordinary running of the club for members are excluded from the corporation tax computation. Any surplus is not taxable, and equally, any deficit is not tax deductible.
Not all club income is covered by the principle of mutuality. Corporation tax is chargeable on non-mutual income, even where the club’s overall trading result shows a deficit on its mutual activities.
Corporation tax will generally be payable on non-mutual income, including:
A common source of confusion arises where a club incurs a loss on mutual trading with members but generates taxable non-mutual income. Deficits arising from mutual trading are not recognised for corporation tax purposes and cannot be carried forward or set against taxable profits.
Many clubs carry on both mutual and non-mutual activities, which can give rise to corporation tax liabilities even where the club is primarily member-focused.
This commonly arises where a club holds both a premises licence and personal licences, allowing significant trade with non-members; or the club regularly admits visitors, for example golf clubs or clubs hosting open competitions, functions or events.
In such cases, income derived from non-members is taxable and must be separately identified. HMRC scrutiny of non-member income has increased in recent years, particularly in relation to visitor bar sales and green fees.
Where income is derived from mixed sources, such as bar takings, it is necessary to apportion income between members and non-members on a reasonable and consistent basis. The direct costs of earning non-member income (for example, stock purchases and bar staff wages) are generally allowable in full. HMRC will also accept a reasonable apportionment of overhead costs, provided the method used is supportable and applied consistently.
Where taxable and non-trading income becomes significant, sporting clubs may benefit from applying for Community Amateur Sports Club (CASC) status. CASC status provides a number of tax advantages, including exemptions from corporation tax on certain income streams and reliefs designed to support community sport.
Eligibility for CASC status is tightly defined. In particular, a club must be organised on an amateur basis and must actively encourage participation in eligible sporting activities. Many members’ social clubs will not qualify, as they will not meet the requirement that a substantial proportion of members participate in sport.
Further detail on CASC eligibility and tax treatment is covered separately in the sporting clubs section and in our dedicated guidance on VAT and sporting clubs.
Members’ clubs frequently fall into difficulty with their corporation tax affairs. This often arises from a misunderstanding of mutuality, with officers or advisers incorrectly assuming that all club income is exempt. We are regularly contacted by clubs facing HMRC debt collection action due to undeclared taxable income, with accumulated penalties and interest sometimes approaching or exceeding the original tax liability.
Where a club has taxable income, or HMRC has issued a notice requiring a return, the club must:
From 1 April 2026, penalties for late filing of corporation tax returns have increased significantly, broadly doubling existing fixed penalties to reflect inflation. These changes apply to all companies with a filing date on or after 1 April 2026.
The revised penalty structure is as follows:
In addition, tax-geared penalties apply where returns are filed significantly late:
Making Tax Digital (MTD) for VAT was introduced from April 2019. While it was originally intended that MTD would be extended to corporation tax, this is no longer the case. HMRC confirmed in its Transformation Roadmap published in July 2025 that it does not intend to introduce MTD for Corporation Tax. As matters stand, there is no timetable for mandatory digital reporting for corporation tax beyond existing online filing requirements.
