How Sponsoring a Charity Can Affect Your Taxes

Company directors and business owners responsible for corporate tax planning and charitable giving decisions.

Explains how corporate donations and sponsorships are treated for tax purposes, helping companies maximise relief and comply with HMRC rules.

Ensures compliance with Corporation Tax rules, avoids disallowed deductions, and allows companies to make charitable contributions efficiently.

Charitable Donations

There are special rules in place when a limited company gives to charity. This can include Corporation Tax relief for qualifying donations made to registered charities or community amateur sports clubs (CASC) as including capital allowances for giving away equipment that has been used by a donor company.

However, the rules are different if the company is given something in return for donating, such as tickets for an event.

Donation amountMaximum value of benefit
Up to £10025% of the donation
£101 – £1,000£25
£1,001 and over5% of the donation (up to a maximum of £2,500)

These rules apply to benefits given to any person or company connected with a company, including close relatives.

Sponsorship Arrangements

Payments made in sponsorship of a charity can be treated as business expenses if there is a genuine business-related benefit, such as:

  • Public endorsement or recognition of the company
  • Use of company logo in events or materials
  • Inclusion in charity publications or websites
  • Sale of products or services at charitable events

These expenses can reduce taxable profits, provided the benefit received does not exceed prescribed limits. 

Real-World Application

  • A company donates £10,000 to a registered charity with no tangible benefit in return – the full amount is deductible against Corporation Tax.
  • If a company sponsors a charity event and receives promotional space valued at £1,000, only the donation in excess of the benefit may be deducted.

Risks and Compliance Considerations

  • Exceeding benefit thresholds can result in partial or full disallowance of the deduction.
  • Incorrect classification of sponsorship vs. donation may trigger HMRC review or penalties.
  • Accurate record-keeping is essential to support claims for relief or deductions.
