Pet Sitter Accountant UK — Simplr Accounting

Accountant for
Pet Sitters.

Specialist UK accountants for pet sitters — overnight sits, house sitting, drop-in visits, puppy visits, cat feeding, holiday cover and pet taxi.

Whether you work across one neighbourhood or cover a wide area with multiple clients, we keep your accounts HMRC-compliant, your Self Assessment filed correctly and your expenses fully claimed. We understand how pet sitting income works — seasonal peaks, last-minute bookings, mileage-heavy routes and the real-world costs of running a pet care business — and we make the financial side simple.

01 / Why Simplr

We get how pet sitting businesses actually work.

Most accountants see service income and treat it as simple self-employment. We know the reality — overnight rates, day rates, add-on services, mileage across multiple clients, seasonal spikes over school holidays and Christmas, and the specific compliance requirements of pet care businesses.

01

Pet care business specialists

Overnight sits, house sitting, drop-in visits, puppy visits, cat feeding, medication visits, pet taxi and holiday cover — we understand every service type and exactly which expenses you can claim against your income.

02

Mileage and travel claims

Travel is one of the biggest expenses for pet sitters. You can claim the HMRC approved mileage rate for every business mile driven between clients' homes, or claim actual fuel costs with a business proportion calculation. We make sure you are claiming the right method in the right way.

03

Seasonal income planning

Pet sitting income typically spikes during school holidays, bank holidays and Christmas — and quiets down in January and February. We help you understand your annual profit picture, set aside the right amount for tax and avoid a large unexpected bill at Self Assessment time.

Earning over £50,000 from your pet sitting business? MTD for Income Tax applies from April 2026. We set up digital records and handle all quarterly submissions for you.

06

Fixed monthly fees

No hourly rates, no surprise invoices. A clear monthly fee that covers everything — you know the cost from day one whatever the season brings.

02 / How we help

Everything a pet sitter needs.

From your first Self Assessment to ongoing bookkeeping, VAT, limited company accounts and tax planning — we handle the financial side so you can focus on looking after pets and keeping clients happy.

03 / Expenses

Every cost you can claim.

Pet sitting businesses have more claimable costs than many sitters realise — particularly around travel and the practical costs of being trusted with clients' homes and animals. Claiming every legitimate expense is the most effective way to reduce your tax bill legally.

Mileage or fuel costs between client visits
Parking fees at client locations
Key cutting and key safe costs
Pet sitting and public liability insurance
DBS check fees
Booking platform and software subscriptions
Website hosting and domain costs
Marketing and advertising spend
Phone costs (business proportion)
First aid training for pets
Home office allowance (where applicable)
Accountancy fees and bookkeeping software
Mileage — your biggest deduction

Claiming travel between client visits correctly

Travel between client homes is a legitimate business expense — but only if claimed correctly. The HMRC approved mileage rate is 45p per mile for the first 10,000 miles per year and 25p thereafter. You must keep a mileage log recording the date, destination and business purpose for each journey. Driving from home to your first client and back from your last client is generally not claimable — but travel between clients during the day is. We set up your mileage records so every claimable mile is captured.

Platform income and reporting

Rover, Trusted Housesitters and booking platforms

If you take bookings through platforms like Rover, Trusted Housesitters or similar, all income received through these platforms is taxable — including tips paid through the platform. Some platforms may also share income data with HMRC. We make sure your declared income matches what the platforms report and that platform fees and service charges are correctly recorded as deductible expenses against your gross income.

Seasonal cash flow

Planning for the January quiet period

Pet sitting income typically peaks across school holidays, particularly summer and Christmas. After a busy end of year, January and February can be significantly quieter — but the Self Assessment payment deadline falls in January. We help you calculate how much to set aside throughout the year based on your projected annual income, so the payment deadline never comes as a shock.

04 / Key thresholds

you stand.

Whether you are just starting out with a handful of regular clients or fully booked months in advance, these thresholds determine how you report and pay tax on your pet sitting income.

06 / FAQs

Pet sitter tax questions, straight answers.

Everything you need to know before booking a call.

Do pet sitters pay tax in the UK?
Yes. If you are running a pet sitting or house sitting business as a UK resident, your earnings count as taxable income. Once you earn over £1,000 in a tax year, you need to register as self-employed with HMRC and file a Self Assessment tax return. This applies whether you pet sit full-time or as a side income.
What income do I need to declare from pet sitting?
All of it. Income from overnight sits, house sitting, daytime drop-in visits, puppy visits, cat feeding, medication visits, pet taxi and any other pet care services you offer. You report gross income then deduct allowable expenses to calculate your taxable profit.
What expenses can pet sitters claim?
Mileage or travel costs between clients, parking fees, key cutting, insurance, DBS check fees, booking platform and software subscriptions, website hosting, marketing, phone costs (business proportion), pet first aid training, home office costs where applicable and accountancy fees.
How does mileage work for pet sitters?
You can claim 45p per mile for the first 10,000 business miles per year and 25p per mile thereafter at the HMRC approved mileage rate. You must keep a mileage log with the date, destination and business purpose for each journey. Travel between client homes during the day is claimable — driving from home to your first visit and from your last visit back home generally is not. We set up your records so every claimable mile is captured correctly.
Do pet sitters need to register for VAT?
If your taxable turnover exceeds £90,000 in any 12-month period, you must register for VAT. We handle registration and quarterly submissions so you stay compliant. See HMRC's guidance on VAT registration for the rules.
Should I set up a limited company for my pet sitting business?
It depends on your income level and personal circumstances. A limited company can be more tax-efficient once profits reach a certain threshold, but it comes with additional admin and compliance requirements. We run the numbers and advise whether incorporation makes sense for where you are right now.
Is my information kept private?
Absolutely. We are bound by strict professional confidentiality rules and GDPR. Your financial information is stored securely in encrypted, cloud-based software. We will never share your data with anyone without your explicit permission.
