Is sponsorship
tax deductible?

Partly. Sponsorship is allowable when it is a genuine business promotion, paid wholly and exclusively to advertise the business (HMRC BIM42555). If there is any personal reason for it, such as sponsoring your child's team or a cause you support, no deduction is due, and any hospitality in the package is disallowed as entertainment.

Sponsoring a local football team, a charity run or a community event is a common way for small businesses to get their name seen. HMRC accepts that sponsorship can be advertising, and allows it. The difficulty is purpose: if you are sponsoring something because your child plays in the team or you care about the cause, the payment has a personal purpose, and the law then allows nothing.

Is sponsorship tax deductible?

The HMRC rule

Advertising, mailshots, free samples and website costs are allowable. The rule comes from Subscriptions, HMRC Business Income Manual BIM37007: wholly and exclusively.

HMRC's manual says sponsorship costs are allowable except where they are capital expenditure, not wholly and exclusively for business purposes, or specifically disallowed, such as entertaining. It adds that if there is a non-business purpose to the sponsorship, even if there is also a business purpose, no allowance is due (BIM42555). GOV.UK says you cannot claim donations to charity, but you may be able to claim for sponsorship payments (marketing, entertainment and subscriptions).

When you can claim it

• Sponsorship with clear advertising in return, such as your logo on kit, banners or programmes.
• Sponsoring events attended by your target customers.
• Sponsorship packages, excluding the hospitality element.
• Product placement and paid promotion by sponsored individuals.

When you cannot

• Sponsoring your own child’s team or activities.
• Sponsorship motivated by a personal interest, such as your hobby.
• Hospitality, tickets and meals included in a sponsorship package.
• Charitable donations described as sponsorship.

What to claim instead

If the real motive is to support a charity, make a Gift Aid donation: the charity claims basic-rate tax, and if you pay higher-rate tax you claim extra relief on your return. It is a better route than a sponsorship claim that could be challenged.

How to decide if you can claim it

1. Was it for the business? A cost is only allowable if you incur it wholly and exclusively for the business. If it also serves a personal purpose that cannot be separated, such as clothing that keeps you warm or a meal that keeps you going, HMRC disallows it.
2. Is part of it personal? Where a cost has a business part you can identify, such as the business calls on a phone bill or the business miles in a car, you claim that part and leave the rest out, on a reasonable basis you can explain.
3. Is it a running cost or something you keep? It is a running cost, so on the cash basis it counts when you pay it and on traditional accounting when you incur it. Nothing about it needs spreading over later years.
4. Is there a specific rule? For sponsorship, the deciding rule is advertising and marketing: advertising, mailshots, free samples and website costs are allowable.

Worked example: a roofer sponsors a club

A roofer pays £1,200 to sponsor a local rugby club's shirts and pitch-side boards, where his customers watch matches, and the package includes £300 of match-day hospitality. The £900 of advertising can be allowable, but only if he has no personal connection with the club. If his son plays for the team, HMRC could argue there is a personal purpose and disallow all of it.

The purpose test

The question is why you made the payment. A business that sponsors an event because its customers attend and the sponsorship gets its name in front of them has a business purpose. A business owner who sponsors their own child's club, or a sport they play, has at least a partly personal purpose, and a dual purpose means no deduction at all. Evidence of what you got in return, and why you chose that sponsorship, matters. A written agreement setting out the promotion you receive, photographs of your branding at events, and figures on the audience reached all help show the payment was advertising, rather than support for something you care about personally.

What you get in return

Sponsorship that gives visible advertising, such as your name on shirts, boards, programmes, websites or social media, looks like advertising. Sponsorship with no promotional return looks like a donation. Compare the cost with what you would pay for similar advertising elsewhere, and keep evidence of the promotion.

Hospitality in packages

Many corporate sponsorship packages include tickets, meals or hospitality boxes. That element is business entertainment, disallowed like any other entertaining. Split the package between advertising and hospitality, using the provider's breakdown where they give one.

Sponsoring individuals

Sponsoring an athlete, performer or content creator can be advertising if they promote your business in return. HMRC looks carefully at payments to individuals, especially relatives. A tribunal found in one case that sponsorship of a family member's sporting career was not paid wholly and exclusively for the business.

Charity events

Sponsoring a charity event can still be advertising if you receive genuine promotion in return. A simple donation to the charity, even if announced publicly, is not; it can get relief through Gift Aid instead.

Where it goes

Allowable sponsorship goes in advertising and business entertainment costs, box 24 of the full self-employment pages. Any hospitality element also goes in the disallowable box 39.

Where it goes on your return and in MTD

For a sole trader, the allowable part goes under advertising costs (SA103F box 24 on the full self-employment pages). Under Making Tax Digital for Income Tax, it goes in the same category of your quarterly update, which is the category TapTax files it under when you record the cost.

If your turnover was under £90,000, you can use the short self-employment pages (SA103S), which ask for a single figure for total allowable expenses rather than a box-by-box breakdown, and the full pages let you give just a total in box 31 too. The category still matters for your own records and for Making Tax Digital, where each quarterly update uses the same categories unless you choose to send one consolidated figure.

Most sole traders now use the cash basis, the default from the 2024/25 tax year, which counts a cost when you pay it. On traditional accounting you count it when you incur it, and equipment you keep goes through capital allowances rather than expenses.

How much an allowable cost saves

The value of a deduction is the tax it removes from your profit, not the cost itself. At the basic rate a sole trader saves 26p for every pound of allowable expense, at the higher rate 42p, and in the personal allowance taper between £100,000 and £125,140 as much as 62p. Landlords pay no Class 4 on rental profit, so they save 20p or 40p.

What £1,000 of allowable expense saves a sole trader in 2026/27

• Basic rate (20% + 6%)£260
• Higher rate (40% + 2%)£420
• Additional rate (45% + 2%)£470
• Allowance taper band (60% + 2%)£620

Records to keep

Keep invoices and a copy or screenshot of each advert, campaign or listing, with a note of what it promoted. For events, sponsorship and gifts, keep a note of who was involved and what the business got in return. Records must be kept for at least five years after the 31 January deadline for the tax year.

From 6 April 2026, sole traders and landlords with qualifying income over £50,000 keep these records digitally and send quarterly updates under Making Tax Digital, falling to £30,000 from April 2027 and £20,000 from April 2028. The MTD requirement checker shows when it applies to you.

Common mistakes

• Claiming sponsorship of a family member’s team or activity.
• Claiming the hospitality part of a package.
• Calling a charitable donation sponsorship.

Related expenses

This item sits in the advertising costs category, alongside advertising and marketing and website and domain costs. The A to Z of expenses answers the same question for every other cost.

TapTax sorts each cost into the right category as you record it, applies the business share where you set one, and keeps the receipts with the figures, ready for your quarterly updates and final return.
