Is pet sitting classed as self-employment for tax purposes?
Yes. Regular paid pet sitting is trading income and is subject to income tax and NI once profits exceed the £12,570 Personal Allowance and NI thresholds.
Full answer
HMRC treats pet sitting, dog walking, and similar animal care services as self-employment if carried out with a view to profit on a regular basis. You must register for Self Assessment if gross income exceeds £1,000 in a tax year (the trading allowance). Keep records of income and deductible expenses such as insurance, equipment, and transport. Profits up to £12,570 fall within the Personal Allowance (no income tax). Profits between £12,570 and £50,270 are taxed at 20% plus 6% Class 4 NI in 2026/27. Class 2 NI at £3.45/week applies if profits exceed £6,725. If you are also employed, both income streams are assessed together for determining your tax band.
