If you’re in the business of trading (or dealing) in cryptoassets you need to pay income tax on your profits.

Working out if you’re in the business of trading in cryptoassets

Trading (or dealing) involves buying and selling cryptoassets to make a profit.

The main way to tell if you’re in the business of trading in cryptoassets is by looking at:

Other things to consider are:

  • the reasons for your transactions
  • whether your activity is organised and systematic
  • how long you hold your cryptoassets
  • the amount you invest.

It’s likely that you’re in the business of trading in cryptoassets if you:

  • have a high number of transactions
  • spend a lot of time and effort managing your cryptoasset portfolio
  • work on your cryptoasset portfolio on a fairly continuous basis.

If you are in the business of trading cryptoassets, your cryptoassets are likely to be trading stock.

Cryptoasset businesses

Trading in cryptoassets if you work full-time

If you have a full-time job and spend some of your spare time buying and selling cryptoassets, you’re probably not a trader unless your activity is highly organised and structured.

Even if you’re not a trader, you’ll still need to pay tax on any gains if you bought your cryptoassets for the purpose of selling or exchanging them.

Cryptoassets that are not part of your trading business

If you’re a trader you might have some cryptoassets that are separate from your trading business.

If you claim that cryptoassets you sold were not part of your trading business, you will need clear and compelling evidence to show that they were not part of your trading business when you both bought and sold them. 

If you hold cryptoassets that are not part of your trading business, you will still need to pay tax if you:

  • bought those cryptoassets to sell or exchange
  • are carrying on a profit-making scheme.

Mizuki is not trading in cryptoassets

Mizuki has a full-time job as a mechanic and buys $50 worth of Bitcoin every week. They set up an automatic payment to a cryptocurrency exchange and the exchange deposits the Bitcoin into their wallet every week.

Mizuki keeps a casual eye on the market and sometimes buys a little more Bitcoin or some altcoins. Occasionally they sells some of them.

Mizuki is not in the business of trading in cryptoassets. Although they have a reasonably high number of transactions on a continual basis, the time and effort put into buying and selling cryptoassets is not significant, and the amount of money invested is relatively small.

Even though Mizuki is not a trader they will still need to pay tax on any gains if they bought cryptoassets for the purpose of selling or exchanging them.
