Dog groomers and walkers: keeping track of allowable business expenses
ONLY£15A MONTHPet businesses often mix specialist equipment with everyday purchases.
Pet businesses often mix specialist equipment with everyday purchases. Shampoo bought for paying customers has a different purpose from food for your own dog. A useful bookkeeping routine records that distinction while the details are still clear.
Follow the service you provide
For grooming, review professional shampoos, cleaning products, disposable supplies, blade servicing and salon costs. Hydrobaths, dryers and grooming tables need equipment treatment appropriate to the accounting basis. A mobile installation may include both a vehicle and separate equipment.
For walking and sitting, assess business insurance, advertising, booking software and equipment used for customers' animals. Record private use of shared items. Training should relate to the existing business under the applicable rules; a course opening an unrelated trade requires different analysis.
Keep local requirements specific
Licensing requirements depend on the activity and location. Do not assume that every dog walker needs the same licence as an animal boarding business. Keep the actual licence, registration or insurance documents supporting the costs incurred.
Client collections can also create transport costs. Record the business journey and use the chosen vehicle method consistently. A trip that includes a personal errand needs an appropriate distinction rather than an automatic claim for everything.
Worked example: a mixed supplier order
A groomer pays £180 for salon shampoo, £40 for blade servicing and £30 for a product for their own pet. The business items total £220; the full £250 payment should not become an allowable expense by default.
Retain the invoice and mark the £30 private element. The same approach works when a supplier sells both professional supplies and household products under one bank description.
Start with the business purpose
An expense category describes a cost; it does not decide whether the cost qualifies for relief. The starting point is whether the spending was for the trade. Where an identifiable part was private, keep that part out of the claim. A personal withdrawal is not an expense simply because it leaves the business bank account.
HMRC's self-employed expenses guide explains the distinction between running costs, capital expenditure and private use. For example, a supplier may sell both equipment and household products. The shop's name is useful evidence, but the invoice tells you what you bought.
Record the full transaction and the business calculation clearly. If a £120 bill has £30 of identifiable private spending, a £90 business claim is easier to explain when both amounts and the reason for the split are retained. Do not delete the private part merely to force the bookkeeping total to resemble the tax deduction.
Nor is a deduction a reimbursement. Spending £100 to save a fraction of that amount in tax still leaves you with a real cost. Buy what the business needs, keep appropriate evidence and claim the relief available under the correct rules.
Give equipment its own review
The tax treatment of equipment depends on the accounting basis and the asset, not just its price. Under the cash basis, many business equipment purchases are deducted when paid. Cars and certain other expenditure are exceptions. Under traditional accounting, a purchase with lasting business use may instead enter the capital-allowances calculation.
HMRC's capital-allowances guide explains the available routes. Annual Investment Allowance can cover qualifying plant and machinery, subject to its conditions and limit, but it does not apply to cars. Accounting depreciation is not itself the tax deduction.
Keep the purchase invoice, date, payment evidence and any finance agreement. A finance instalment can combine capital and interest, so treating every payment as an ordinary running cost may give the wrong answer. Record private use where relevant and retain the disposal paperwork when equipment is sold or part-exchanged.
For an expensive or unusual purchase, resolve the treatment before relying on a tax estimate. A category chosen from the merchant name cannot tell you whether an item was bought outright, leased, used privately or acquired as part of a larger building project.
Reconcile receipts, not just bank payouts
A bank deposit is not always the original sale. A platform, card processor or agent may deduct fees before sending you the balance. Keep the statement showing the gross amount, deductions, refunds and final payout, then explain the difference in your records.
Cash needs the same attention. Record customer cash when received under the cash basis, even if some of it is spent before the rest reaches the bank. Banking cash already recorded as a sale is a transfer between your cash and bank records, not another sale.
HMRC's record-keeping guidance covers income and business expenses. The useful practical test is whether another person could follow a payment from the original sale to the amount received without counting it twice.
Do not use bank feeds as a reason to ignore payment accounts, credit cards, cash or payments made personally for the business. List every place where business money passes, choose the source for each type of transaction and review transfers between those sources. This turns reconciliation into a repeatable check rather than a search through several unrelated statements.
Build a short weekly routine
Match appointments to cash and card receipts, attach supplier invoices and identify personal items. Review larger purchases before relying on a tax estimate. Separate customer or animal-care notes from the financial references needed to explain payments.
