Dog Walking and Pet Sitting Tax — A Self-Employed UK Guide for 2026/27
Turning a love of dogs into paid dog walking or pet sitting work creates real UK tax obligations. Registration, expenses and insurance considerations for 2026/27.
When a Favour Becomes a Business
Many dog walkers start informally — helping a neighbour, then a friend of a neighbour, gradually building a small round of regular clients. The tax question is not about intent or how it started, but about the actual income generated: once gross income from dog walking and pet sitting (combined with any other casual self-employment) exceeds £1,000 in a tax year, Self Assessment registration is generally required, regardless of how informal the arrangement feels.
The Real Cost of Skipping Insurance
While not a legal tax requirement, professional dog walking carries genuine liability risk — an injury to a member of the public, damage to property, or an incident involving a dog in your care could result in a costly claim without appropriate insurance. Public liability insurance and care/custody/control insurance (specifically covering animals while in your professional care, which standard public liability sometimes excludes) are strongly recommended, and the premium cost is a straightforward allowable business expense once you're trading.
| Expense | Generally allowable? |
|---|---|
| Public liability insurance | Yes |
| Care/custody/control insurance | Yes |
| Dog walking equipment (leads, poo bags, treats) | Yes |
| Mileage between client visits | Yes, at standard HMRC rates |
| Local authority licence fee (if required) | Yes |
| Normal commute from home to a single regular workplace | No — this is never deductible |
Mileage Between Clients: A Genuinely Valuable Deduction
For dog walkers driving between multiple clients' homes across a working day, mileage claimed at the standard HMRC rate can represent a meaningful deduction over a full tax year — 45p per mile for the first 10,000 business miles, 25p thereafter, provided a mileage log is kept recording dates, routes and business purpose. This applies to travel between appointments, not the initial journey from your own home to your first appointment of the day, which is generally treated the same as an ordinary commute and not deductible.
Local Licensing: A Separate Regulatory Question
Some local authorities in the UK require a licence for professional dog walkers taking multiple dogs into public parks or open spaces simultaneously, as a public safety and animal welfare measure — this is entirely separate from tax registration and needs checking with your specific council. Where a licence is required and obtained, its cost is itself an allowable business expense.
Getting Set Up Properly
- Track gross income against the £1,000 trading allowance threshold
- Obtain appropriate public liability and care/custody/control insurance
- Keep a mileage log for travel between client appointments
- Check local council licensing requirements for group dog walking
- Register for Self Assessment once income exceeds £1,000

Frequently asked questions
Do I need to register as self-employed for occasional dog walking for neighbours?
Only if your gross income from dog walking (and any other casual self-employment combined) exceeds £1,000 across the tax year — the trading allowance covers modest, occasional amounts below that without requiring registration. A regular dog walking round with several clients, even if each individual payment is small, can add up to exceed £1,000 across a full year, at which point registration becomes necessary.
What insurance do dog walkers and pet sitters need, and is it a tax-deductible expense?
Public liability insurance (covering injury to third parties or damage to property while working) and, ideally, care/custody/control insurance (covering the animals themselves while in your care) are strongly recommended for anyone doing this professionally, given the genuine risk of an incident. The cost of appropriate business insurance is a straightforwardly allowable business expense, deductible against your dog walking or pet sitting income.
Can I claim mileage for driving between clients' homes?
Yes — mileage between different appointments during your working day (as opposed to your normal commute from home to a single regular workplace) is generally an allowable business expense, claimed using the standard HMRC mileage rate (45p per mile for the first 10,000 business miles in a tax year, 25p thereafter) if using your own vehicle, provided you keep a log of business mileage.
Do I need a specific licence to walk multiple dogs at once professionally?
Local authority licensing requirements for professional dog walkers vary — some councils require a licence for walking a certain number of dogs simultaneously in public spaces (particularly parks), separate from any tax registration requirement. This is worth checking with your specific local council, since it's a regulatory rather than tax matter, though any required licence fee would itself typically be an allowable business expense once you are trading.
