Running a dog walking business comes with more costs than many people realise. The good news is that many of those costs can be claimed as business expenses, as long as they are wholly and exclusively for your work.

This guide covers 15 common expenses UK dog walkers can often claim, plus the record-keeping habits that make tax season much easier. For wider tax support, visit our accountant for dog walkers page.

What Makes an Expense Allowable?

HMRC generally allows expenses that are incurred wholly and exclusively for your business. If something is partly personal and partly business, you should only claim the business-use portion.

You can read HMRC's general guidance on expenses if you are self-employed.

A Note on Mileage

Travel is one of the biggest costs for many dog walkers. You may be able to claim either business mileage using HMRC's simplified mileage rates or a business percentage of actual vehicle costs.

The right method depends on how you work and what records you keep. Read our dedicated guide: Can Dog Walkers Claim Mileage?

A Note on Home Office Costs

If you run the admin side of your business from home, you may be able to claim home working costs. This is often done using HMRC's simplified expenses method or a reasonable apportionment based on time and space.

GOV.UK explains the flat-rate method in its guide to simplified expenses for working from home.

Getting Expenses Right as a Dog Walker

The rules can be nuanced, especially when something has both personal and business use. A phone bill, vehicle, internet connection or item of clothing might be partly claimable, fully claimable or not claimable depending on the facts.

At Simplr Accounting, we help dog walkers across the UK stay on top of records and claim legitimate expenses while keeping things simple, compliant and tax-efficient.

If in doubt, ask before guessing. Clean records and sensible claims are much easier to defend than aggressive expenses with no evidence.

How to Keep Expense Records

01Keep receipts. Save digital copies of insurance, equipment, supplies and software receipts.
02Separate business spending. A dedicated business bank account makes tracking much easier.
03Log mileage as you go. Record date, route, purpose and miles for each business journey.
04Use clear categories. Group costs such as insurance, travel, supplies, marketing and professional fees.
