Dog Walker Tax Expenses: What You Can Claim

Running a dog walking business in the UK is incredibly rewarding, but when tax season rolls around, many professionals find themselves overwhelmed. The difference between a struggling business and a profitable one often comes down to one thing: how effectively you manage your allowable expenses.

Every pound you claim as a legitimate business expense is a pound you don’t pay tax on. However, HMRC has strict rules. To be “allowable,” an expense must be incurred **wholly and exclusively** for the purposes of your trade.

In this comprehensive guide, we’re going deep into the 15+ categories of expenses you need to track to keep your tax bill as low as possible while staying firmly on the right side of the law.

1. Specialist Pet Business Insurance

Insurance isn’t just a safety net; it’s a legal and professional necessity. HMRC allows you to deduct the full cost of premiums for:

• Public Liability Insurance (essential for when a dog is in your care).
• Professional Indemnity (covers your professional advice).
• Care, Custody, and Control (specifically for the animals themselves).

2. Walking Equipment & Consumables

Don’t make the mistake of paying for “work tools” out of your personal pocket. If you buy it to walk a client’s dog, it’s an expense.

• Leads and Harnesses: Including specialist dual-control leads or muzzles.
• Poo Bags: These add up! Whether you buy in bulk or grab them on the go, keep the receipts.
• Cleaning Supplies: Towels for muddy paws, disinfectant for your van, and hand sanitiser.

3. Treats, Toys, and Enrichment

If you use treats to reward good behavior during a walk or toys to keep a high-energy breed engaged, these are claimable. Pro Tip: Ensure these are kept separate from any items you buy for your own personal pets to avoid “dual-purpose” complications with HMRC.

4. Vehicle Costs and Business Mileage

For most UK dog walkers, travel is the largest expense. You have two ways to claim this, and choosing the right one is vital.

The Mileage Rate Method

As of 2026, the standard HMRC rates are usually 45p per mile for the first 10,000 miles and 25p thereafter. This covers fuel, insurance, and wear-and-tear. It is simple, but requires a meticulous mileage log.

The Actual Cost Method

If you have a dedicated dog walking van, you might prefer to claim a percentage of actual costs (fuel, repairs, MOT, insurance). Which is better? Usually, if you drive an older, fuel-efficient car, the mileage rate is more profitable. If you have a brand-new, expensive-to-run van, actual costs might win.

5. Home Office & Administrative Costs

Do you spend your evenings replying to emails, updating your Instagram, or managing bookings? You are running an office.

• Software: Subscriptions to booking apps like Pet Sitter Plus or accounting software like Xero/QuickBooks.
• Use of Home: You can use HMRC’s simplified flat-rate (e.g., £6 per week) or calculate the proportion of your heating and electricity used for business hours.
• Phone & Internet: If your phone is 50% business use, you claim 50% of the bill.

6. Marketing and Business Growth

To get dogs on the lead, you need to get your name out there. Claim for:

• Website hosting and domain registration.
• Facebook/Instagram ad spend targeted at your local area.
• Branded clothing (which also helps with the “Professionalism” claim).

7. Professional Fees and Memberships

To stay competitive, many dog walkers join professional bodies like the NARPS (National Association of Pet Sitters & Dog Walkers). Your annual membership fees are fully claimable. Additionally, if you hire an accountant to file your Self Assessment, their fee for preparing your business accounts is a tax-deductible expense.

8. Bank Charges and Payment Processor Fees

If you use a business bank account that charges a monthly fee, that is an allowable expense. More importantly, don’t forget the transaction fees. If you take payments via Stripe, PayPal, or a SumUp card reader, those providers take a percentage. You should record the full sale as income and the fees as a business expense.

9. Software and Tech Subscriptions

In 2026, dog walking is high-tech. You can claim for:

• Booking Systems: Software that handles your scheduling.
• Route Planning: Premium versions of maps or GPS tracking apps.
• Accounting Software: Subscriptions to apps like QuickBooks or FreshBooks.

10. Training and CPD (Continuing Professional Development)

HMRC allows you to claim for training that maintains or updates your existing skills. This includes:

• Canine First Aid refreshers.
• Dog behaviour workshops.
• Business management courses specifically for pet professionals.

Note: You generally cannot claim for training that teaches you a completely new set of skills (like switching from dog walking to becoming a qualified Vet).

11. Clothing and PPE (The Strict Rules)

This is a common “audit trigger.” You cannot claim for your everyday walking boots or a standard North Face jacket. To be allowable, the clothing must be:

• Branded: A hoodie with your business logo.
• Protective: High-visibility vests or steel-toed boots if required for safety.
• Specialist: Heavy-duty waterproof over-trousers used exclusively for work.

12. Repairs and Maintenance

If you use a van, the MOT, new tires, and servicing are part of your “Actual Costs” (if you aren’t using the mileage rate). Even if you don’t have a van, you can claim for repairs to business assets—for example, getting a professional grooming table or a heavy-duty crate repaired.

13. Printing and Stationery

Even in a digital world, physical items matter. Claim for:

• Printer ink and paper for contracts.
• Laminating sheets for emergency contact cards.
• Post-it notes, pens, and planners.

14. Secure Key Storage and GPS

Security is a massive part of a dog walker’s responsibility. The cost of secure key cabinets, magnetic key safes for your vehicle, or GPS trackers attached to client collars are all valid business expenses.

15. First Aid Kits and Safety Gear

Keeping a specialized dog first aid kit in your bag or vehicle is a claimable expense. This also extends to safety items like portable fire extinguishers for your van or personal safety alarms for yourself during winter evening walks.

The Common Mistakes: What HMRC Won’t Let You Claim

To keep this guide natural and honest, we have to look at the “Grey Areas.”

1. Ordinary Clothing: You cannot claim for “work clothes” like jeans or trainers, even if you only wear them for dog walking. It must be protective (waterproofs) or branded (uniform).
2. Your Own Dog’s Food: Even if your dog “helps” you walk others, their costs are personal.
3. Fines: Speeding tickets or parking fines incurred while working are NEVER claimable.
