“I sponsored a friend’s charity run — can I put it through the business?”
Short answer: only if you get advertising in return.
And HMRC is very clear about this in BIM45085.
🎗️ HMRC’s rule
If the payment is mainly to support the individual or cause, it’s not allowable.
If the payment gives your business public advertising, it may be allowable.
✔️ Allowable charity sponsorship
(according to BIM45080)
• Your logo appears on event materials
• You get a link on the charity’s website
• You receive measurable promotional exposure
• The sponsorship is structured as advertising
❌ Not allowable
• Personal donations
• Sponsoring someone because you like them
• Payments with no advertising return
• Anything driven by personal motives
HMRC’s wording in BIM45085 is blunt:
If the purpose is not wholly for business, the deduction fails.
If it’s marketing, great.
If it’s generosity, it’s not a business expense.
