Is pet insurance
tax deductible?

No, for a pet. Insurance and vet bills for a family pet are personal (GOV.UK). Animals used in the business, such as a guard dog for premises, a working sheepdog or animals a trainer uses with clients, are different: their insurance, food and vet costs can be allowable.

Plenty of sole traders bring their dog to work, or feature their pet in their marketing. That does not make the pet a business asset. Only animals genuinely used in the trade, such as guard dogs, working farm dogs or animals a trainer or groomer works with, have allowable costs.

Is pet insurance tax deductible?

The HMRC rule

A cost is only allowable if it is incurred wholly and exclusively for the business. Everyday living costs, health, appearance and leisure have a personal purpose, so they are not allowable even when they help you work. The rule comes from HMRC Business Income Manual BIM37007: wholly and exclusively, Legal and financial costs.

Only costs incurred wholly and exclusively for the business are allowable (expenses overview). Costs of a family pet are personal. Costs of animals kept for the trade, such as a guard dog or a working dog, are incurred for the business and can be allowable.

When you can claim it

• Insurance, food and vet bills for a guard dog kept for business premises.
• Costs of working farm animals and sheepdogs.
• Costs of animals used in the trade, such as a dog trainer’s demonstration dog.
• Public liability insurance for a pet business.

When you cannot

• Pet insurance for a family pet.
• Vet bills and food for a pet that comes to work.
• A pet featured in social media content, in most cases.
• A dog walker’s or pet sitter’s own pets.

What to claim instead

If you run a pet business, claim the costs of the business itself: public liability insurance, equipment, travel and training. Your own animals stay personal unless they are genuinely working animals in the trade.

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 pet insurance, the deciding rule is personal costs: a cost is only allowable if it is incurred wholly and exclusively for the business. Everyday living costs, health, appearance and leisure have a personal purpose, so they are not allowable even when they help you work.

Worked example: a dog trainer

A dog trainer has two dogs: a trained demonstration dog she uses in every class, and a family pet. Insurance, food and vet bills for the demonstration dog, £1,100 a year, are arguably business costs because the dog is used in the trade. The family pet's £700 of costs are personal. If the demonstration dog is also the family pet, a personal element makes the claim much weaker.

The wholly and exclusively test

An expense is allowable only if it is incurred wholly and exclusively for the purposes of the business. HMRC's manual explains that some costs have an intrinsic duality of purpose: they meet a personal need, such as health, warmth or appearance, whatever else they do. Where a personal purpose is part of the reason for the spending, even a small part that cannot be separated, the whole cost fails the test.

Working animals

Animals kept for the trade, such as working sheepdogs on a farm, guard dogs for business premises, or horses in a riding school, are part of the business. Their feed, vet bills and insurance are allowable. The more the animal is also a family pet, the weaker the claim.

Pet businesses

Dog walkers, groomers, trainers and pet sitters can claim the costs of running their business, such as insurance, leads, grooming equipment, travel and training. Their own pets are personal, even if they come along on walks.

Pets in content

Content creators who feature pets sometimes treat them as business assets. HMRC is likely to see a pet as personal, however much content it appears in. Specific costs for a sponsored shoot, such as props, are more arguable than the pet's everyday costs.

Paying personal costs 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 in your bookkeeping 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.

Where it goes

Costs of working animals go in other business expenses, box 30. Pet business insurance goes with other insurance. Personal pet costs go nowhere on the return.

Where it goes on your return and in MTD

Because it is not allowable, a sole trader leaves it out of expenses altogether. If it went through your business account, record it as drawings or a non-business payment, and if your accounts include it, add the same amount back in the disallowable column of 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.

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

You do not need business records for personal costs. If a personal cost was paid from the business account, record it as drawings so it is excluded from your expenses. For any business element you do claim, keep the receipt and a note of the business reason.

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 a family pet that comes to the office.
• Claiming a pet because it appears on social media.
• Dog walkers claiming their own dogs.
