If you are a dog walker in the UK, understanding how tax works is one of the first things you will need to get to grips with.
This guide explains dog walker tax in the UK in simple terms, so you know what to expect.
It’s one of the most common questions people ask when they first go self employed.
The simple answer is yes, most dog walkers do need to pay tax, but it’s usually much more straightforward than people expect.
Do you need to register as self employed as a dog walker?
You need to register as self employed with HMRC if your dog walking income is more than £1,000 in a tax year.
This £1,000 is known as the trading allowance.
- If you earn less than £1,000, you do not need to register
- If you earn more than £1,000, you do
This applies whether dog walking is your full time work or something you do alongside a job.
You can register as self employed on the HMRC website
How much tax do dog walkers pay in the UK?
Dog walkers usually pay tax on their profits, not their total income.
Your profit is what’s left after you take away your expenses.
You may need to pay:
- Income tax
- National Insurance
How much you pay depends on how much profit you make over the year.
Do dog walkers need to pay National Insurance?
Most dog walkers will also need to pay National Insurance once they are registered as self employed.
This is usually worked out automatically as part of your tax return, so you do not need to calculate it separately.
What expenses can dog walkers claim?
A lot of people worry about this, but it is normally quite straightforward.
Common dog walking expenses include:
- Mileage when travelling between clients
- Insurance
- Leads, harnesses and other equipment
- A portion of your mobile phone
- Advertising or website costs
Keeping a simple record of your income and expenses throughout the year will make things much easier.
When do you need to register and submit a tax return?
You do not need to register the moment you get your first client.
You register after the end of the tax year in which you went over £1,000.
For example:
- If you earn over £1,000 in the 2025/26 tax year
- You need to register by 5 October 2026
You will then submit a self assessment tax return each year.
What if you are not sure what to do?
This is where most people feel unsure.
You might be wondering:
- Am I doing this properly?
- What counts as an expense?
- When do I need to take action?
That is completely normal, especially when you are starting out.
Do dog walkers need an accountant?
A lot of dog walkers start out managing things themselves, especially in the early stages.
That is completely fine, and for some people it works well for a while.
As your business grows though, things can start to feel a bit less straightforward. Keeping track of expenses, understanding what to claim and making sure everything is done correctly can take up more time than expected.
Having someone handle things for you can take that pressure off and give you confidence that everything is being done properly.
