Not sure if your hobby is actually a taxable trade? HMRC uses ‘badges of trade’ to assess whether an activity is a business. Factors like profit motive, transaction frequency, and asset changes help determine if tax rules apply to your earnings.

The ‘badges of trade’ tests, although not definitive, serve as important tools for HMRC in determining whether an activity constitutes a legitimate economic trade or business, or whether it is simply a personal hobby. There comes a point at which a careful and thorough evaluation is required to assess whether what initially started as a hobby has indeed transformed into a taxable activity.

As part of their investigation into whether a hobby has evolved into a trade, HMRC typically examines the following badges of trade:

  • Profit-seeking motive
  • The number of transactions
  • The nature of the asset
  • The existence of similar trading transactions or interests
  • Changes made to the asset
  • The manner in which the sale was carried out
  • The source of finance used
  • The interval of time between purchase and sale
  • The method of acquisition

It is important to note that there is no statutory definition of the term ‘trade.’ The only statutory clarification available is that ‘trade’ includes a ‘venture in the nature of trade.’ As a result, it is the courts that have provided a definition of what constitutes a ‘trade,’ and these decisions serve as a framework for guiding HMRC’s assessments when disputes arise.

The badges of trade have proven to be valuable indicators in numerous cases, providing practical guidance in distinguishing between a hobby and a taxable trade or business.
