Is political donations
tax deductible?

No. Payments to political parties are never allowable, and GOV.UK lists them specifically among the costs you cannot claim (GOV.UK). HMRC's manual says political subscriptions are almost always made for non-trade purposes (HMRC BIM47405). There is no Gift Aid on political donations either.

Political donations are one of the clearest exclusions in the expenses rules. GOV.UK lists them by name, and there is no alternative relief like Gift Aid. Even a business with a direct interest in a policy cannot deduct payments to a party or campaign.

Is political donations tax deductible?

The HMRC rule

Payments to political parties and donations to charity are not allowable. Sponsorship that is genuinely advertising for the business can be. The rule comes from Subscriptions, Self-employment (full) notes, SA103F.

GOV.UK lists payments to political parties among the subscriptions you cannot claim (marketing, entertainment and subscriptions). HMRC's manual says subscriptions to political parties are almost always made wholly or partly for non-trade purposes and should not be allowed (BIM47405). The SA103F notes list payments to political parties as disallowable (SA103F notes).

When you can claim it

• Trade association membership, which may include lobbying on behalf of your industry.
• Professional body fees.
• Advertising in a publication, at a normal commercial rate, if it genuinely promotes the business.
• Nothing for the donation itself.

When you cannot

• Donations to political parties.
• Payments to candidates or campaigns.
• Tickets to political fundraising events.
• The political fund element of a union subscription.

What to claim instead

If you want your industry's interests represented, a trade association membership is allowable, and many associations lobby on members' behalf. Donations to parties or campaigns come from after-tax income.

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 not a cost of running the business at all, so the accounting basis makes no difference: it never goes in your expenses, although it may have a relief of its own elsewhere on the return.
4. Is there a specific rule? For political donations, the deciding rule is donations and political payments: payments to political parties and donations to charity are not allowable. Sponsorship that is genuinely advertising for the business can be.

Worked example: a fundraising dinner

A builder pays £300 for a ticket to a political party's fundraising dinner and £250 for a trade federation membership. The federation membership is allowable. The dinner ticket is a political donation, and not allowable.

Why political payments are excluded

A political donation supports a cause or party, which is a personal or non-trade purpose, even if the business might benefit from a policy. The law and HMRC's guidance treat these payments as not made wholly and exclusively for the trade.

Fundraising events

Tickets to political dinners and events are donations, whatever networking value they have. They are not business entertainment either, because the purpose is political.

Union political funds

If you pay a trade union subscription that includes a political fund contribution, the political element is not allowable. The rest may be, where the membership relates to your work.

Trade associations

Trade associations and chambers of commerce often represent their members' interests to government. Membership is allowable as a subscription related to your business.

Paying from the business account

Sole traders often pay personal costs from the account they use for the business. That is allowed, but the payment is drawings, not an expense. Record it that way so it does not end up in your expense totals. If your accounts do include it, the full self-employment pages have a disallowable column, box 45 for other expenses, where the same amount is added back.

Campaign groups and pressure groups

Payments to single-issue campaigns, pressure groups and referendum campaigns are treated like political donations when their purpose is to influence policy or elections. Some campaigning bodies are charities, but charities cannot be party political, and donations to them follow the charity rules instead, with Gift Aid rather than a business deduction.

Standing for election yourself

If you stand as a candidate for a council or Parliament, your campaign costs are personal, not business expenses, even if the role would bring you into contact with potential customers. Allowances paid to councillors are taxed separately from your business profits.

Advertising in political publications

Paying for an advert in a party conference brochure or political magazine is sometimes presented as advertising. If the price is far above a commercial rate, or the audience is not your market, the payment looks like a donation and is not allowable. Only a genuine commercial advert, at a normal rate, aimed at your customers, has a chance of being treated as advertising.

Where it goes

Political donations go nowhere on the return. If included in your accounts, the SA103F notes say to add them back in box 45.

Where it goes on your return and in MTD

It is not an allowable expense, so it does not reduce your profit. Where your bookkeeping shows it as a business payment, record it as drawings, or include it and add it back as a disallowable expense on the full self-employment pages.

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.

The accounting basis changes when a cost counts. On the cash basis, the default for sole traders since 2024/25, it counts when you pay it; on traditional accounting, when you incur it, with things you keep claimed through capital allowances.

How much an allowable cost saves

An allowable expense does not come back to you in full: it reduces your profit, so it saves tax at your marginal rate. For a sole trader in England, Wales or Northern Ireland that is 26p in the pound at the basic rate (20% Income Tax plus 6% Class 4 National Insurance) and 42p at the higher rate. The sole trader tax calculator works out the figure for your own profit.

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

You do not need business records for personal costs. If a personal payment was made from the business account, record it as drawings so it is excluded from your expenses. Keep policy documents, statements and receipts in your personal records, because some of them matter for your tax return in other ways.

If Making Tax Digital for Income Tax applies to you (qualifying income over £50,000 from April 2026, £30,000 from April 2027 and £20,000 from April 2028), the records must be digital, and each quarter's costs go into a quarterly update. Check your date with the MTD requirement checker.

Common mistakes

• Claiming political dinners as networking.
• Claiming a union’s political fund element.
• Expecting Gift Aid on political donations.

Related expenses

This item sits in the other business expenses category, alongside art and collectibles, care home fees, charity donations, clothing and workwear, cryptocurrency, fines and penalties, funeral costs and furniture. The A to Z of expenses answers the same question for every other cost.

If you record your costs in TapTax, each one lands in the HMRC category it belongs to, with its receipt attached, so your quarterly updates and year-end return use the same figures.
