Tax Guide for Self-Employed Dog Walkers & Pet Sitters UK
What expenses can a self-employed dog walker claim? Mileage at 45p/mile, CCC insurance, poo bags, branded clothing — with a worked UK tax calculation.
Tax Essentials
- Typical Income
- £18,000–£30,000
- VAT Threshold Risk
- Low risk
If you work as a self-employed dog walker or pet sitter, you report your income through Self Assessment — there's no CIS to worry about, but you'll often be paid in cash and you'll be travel-heavy, which makes mileage your single biggest deduction. Most walkers charge £10–£15 per dog per hour, and when you're walking groups of three or four, the income adds up — but so do the expenses you can claim.
Many dog walkers start as a side hustle alongside another job. If your total self-employed income exceeds £1,000, you need to register with HMRC.
What Dog Walkers Can Claim as Allowable Expenses
| Expense | Examples | Typical Annual Cost |
|---|---|---|
| Travel between clients | Mileage at 45p/mile (first 10,000), then 25p — driving to pick-ups and drop-offs | £1,000–£3,000 |
| Insurance | Public liability + care, custody & control cover (Protectivity, Pet Business Ins.) | £65–£150 |
| Equipment | Leads, harnesses, collapsible water bowls, crates, pet first-aid kit | £100–£300 |
| Consumables | Poo bags, treats, towels, cleaning supplies for your vehicle | £100–£300 |
| Branded clothing | Embroidered hoodies, polo shirts, hi-vis jackets with your business name | £50–£200 |
| Phone & apps | Mobile contract (business portion), booking/scheduling apps | £100–£250 |
| Marketing | Flyers, business cards, website, local Facebook ads, dog show stand hire | £100–£400 |
| Training & memberships | Canine first-aid course, NarpsUK membership, animal behaviour CPD | £50–£200 |
| DBS check | Basic (£21.50) or Enhanced — increasingly expected by clients | £22–£50 |
| Home office | HMRC simplified flat rate (£10–£26/month) for admin, bookings, client comms | £120–£312 |
| Accounting fees | Tax return preparation, bookkeeping | £100–£300 |
Mileage: Your Biggest Deduction
Most dog walkers drive between pick-ups, walking spots, and drop-offs — often several trips per day. At 6,000 business miles per year, the mileage deduction is £2,700. Keep a daily log of every journey — date, route, and miles. A free mileage app running in the background is the easiest way. For the full method comparison (HMRC simplified 45p/25p rate versus actual vehicle costs), see our guide on vehicle and mileage claims.
Insurance: Care, Custody & Control
Standard public liability insurance isn't enough for dog walkers. You need care, custody & control (CCC) cover — this pays vet bills if a dog in your care is injured, falls ill, or causes damage. Combined policies start from ~£65/year for sole traders. This is fully deductible and essential for client trust.
Expenses You Can't Claim
- Your own dog's costs — food, toys, and vet bills for your personal pet aren't business expenses, even if your dog joins you on walks
- Everyday clothing — wellies, waterproof jackets, and walking boots you'd wear anyway don't count. Only branded items with your business name qualify
- Park entry fees for personal visits — only fees paid specifically for commercial dog walking (e.g. Royal Parks licence) are deductible
- Food and drink — coffee and lunch between walks aren't deductible
- Fines and penalties — on-the-spot fines, parking tickets, late filing penalties
Example: How Much Tax Does a Dog Walker Pay?
Amy works as a self-employed dog walker, doing 2–3 group walks per day. Here's her 2025/26 tax year:
| Item | Amount |
|---|---|
| Dog walking income (gross) | £20,000 |
| Mileage (6,000 miles × 45p) | −£2,700 |
| Insurance, equipment, consumables | −£400 |
| Phone, marketing, clothing, training, DBS | −£400 |
| Home office, accounting | −£400 |
| Taxable profit | £16,100 |
| Income Tax (20% on profit above £12,570) | £706 |
| Class 2 NI (profits above £6,845 SPT) | £0 |
| Class 4 NI (6% on profit above £12,570) | £212 |
| Total tax + NI due | £918 |
For 2025/26, Class 2 NI is no longer charged when your profits exceed the Small Profits Threshold of £6,845 — you still get the NI credit toward your State Pension automatically. Without claiming expenses, Amy's tax + NI on £20,000 of profit would be around £1,932. Claiming her allowable expenses saves her about £1,014 — mileage alone accounts for more than half of that.
Record Keeping Tips
- Log every journey to and between clients — note the date, pick-up address, walking location, and miles. HMRC expects a mileage log with dates and distances
- Save your insurance renewal each year — care, custody & control cover is a key deduction. Keep the policy document and payment confirmation
- Track group walk numbers — record how many dogs you walked each day and what each client paid. This helps reconcile income if clients pay in cash
- Keep receipts for branded clothing orders — embroidered hoodies and polo shirts are deductible, but only if they display your business name. Save the order confirmation
- Store your DBS certificate — proof of a deductible expense and a trust signal for new clients
Key Deadlines
| Deadline | What |
|---|---|
| 5 April | Tax year ends — finalise your income and expense records |
| 5 October | Register for Self Assessment (if your first year) |
| 31 January | File Self Assessment and pay any tax owed |
| 31 July | Second payment on account (if applicable) |
If you earn under £1,000 total from self-employed work, you don't need to register or file. See our guide on what records to keep for more detail.
Frequently Asked Questions
How much tax does a self-employed dog walker pay?
A dog walker earning £20,000 gross with around £3,900 in allowable expenses (mainly mileage) has a taxable profit of about £16,100. For the 2025/26 tax year, that's roughly £706 in Income Tax plus £212 in Class 4 NI — a total of around £918. Class 2 NI is no longer charged once your profits exceed the £6,845 Small Profits Threshold. Without claiming expenses, the bill would be closer to £1,932.
Do I have to register with HMRC if I only earn a few hundred pounds dog walking?
No — if your total self-employed income is under £1,000 in the 2025/26 tax year, the trading allowance covers it and you don't need to register or file a return. Once you cross £1,000 gross, you must register for Self Assessment by 5 October following the end of that tax year.
Can I claim leads, treats, and poo bags on my tax return?
Yes — leads, harnesses, treats used on client walks, poo bags, towels, and cleaning supplies for your vehicle are all allowable consumables. Most walkers spend £100–£300 a year on these. Keep receipts and pay through a dedicated business account where possible, so the records line up with your bank statements.
Do dog walkers need a council licence in the UK?
For dog walking itself, most councils don't require a licence — but a few (including several London boroughs and Royal Parks) cap walker numbers or require a permit for commercial groups. If you also offer home boarding or day care, you'll need a licence under the Animal Welfare (Licensing of Activities Involving Animals) Regulations 2018. Licence fees are deductible.
Can I claim mileage driving to clients' homes?
Yes — journeys from your home to pick up dogs, between client houses, and to walking spots all count as business miles. Claim at 45p per mile for the first 10,000 miles in the tax year, then 25p after that. Personal trips and the school run don't qualify, so keep a daily log separating business and personal journeys.
