How Investing vs Trading impacts tax

In most cases of buying and selling cryptocurrency as a retail investor, you are participating in investing rather than trading. The two are treated differently for tax purposes.

  • Investing is subject to capital gains tax or income tax, depending on the nature of the transaction.
  • Trading in this case refers to self-employment which is subject to income tax and National Insurance Contributions.

The key difference between investing and trading – along with the different tax treatments, is how losses generated in the crypto-activity can be used.

In their guidance, HMRC have explicitly stated that they would expect it to be exceedingly rare that any crypto-activity constituting buying & selling crypto would be classified as “trading”.

If you are uncertain, speak to a tax advisor as there are always exceptions, including but not limited to, developing tokens and large scale mining.

How is crypto tax calculated in the United States?

You can be liable for both capital gains and income tax depending on the type of cryptocurrency transaction, and your individual circumstances. For example, you might need to pay capital gains on profits from buying and selling cryptocurrency, or pay income tax on interest earned when holding crypto.

Product Update: Aster DEX and Sei support now live

Summ now supports Aster DEX and the Sei network, making it easier to import perpetual, spot, and on-chain transactions for accurate crypto tax reporting. Connect via API, wallet address, or CSV to simplify your crypto tax calculations and reduce manual tracking.

Key takeaways
This tax guide is regularly updated: Last Update  

Aster DEX and Sei now supported on Summ

We've added direct support for two more networks: Aster DEX and Sei. If you're trading on either platform, you can now import your transactions directly into Summ.

Aster DEX integration

Aster DEX is a non-custodial platform for decentralized perpetual contracts. If you're trading perps on Aster, your transactions can now import directly into Summ to get your tax reports.

We support two import methods, allowing you to choose the one that works best for your workflow:

  • API connection: Securely connect your Aster account via secure API for automatic transaction imports. Set it up once, and sync new transaction data with one click whenever you need it.
  • CSV upload: Prefer to do it yourself? Download your transaction CSV from Aster and drop into Summ to upload your Aster transactions. Same comprehensive data, different approach.

Sei network support

Sei transactions can now be imported by adding your wallet address. The process is straightforward: copy and paste your Sei wallet address under add accounts in the app, and your transaction history will automatically ingest.

Sei is a Layer 1 blockchain designed for trading applications, and if you're using it, your transactions now feed directly into your tax calculations, eliminating the need for manual tracking.

Why it matters

More integrations mean more complete and accurate data. When your transactions import automatically across all the platforms you use, you spend less time hunting down CSVs and more time understanding your tax position.

Summ proudly offers direct support for over 3500 integrations, making it easy to import your transactions and generate precise reports. In the rare event that your integration isn’t listed, all trading can be supported with a custom CSV upload.

Both integrations are live now. Log in or sign up to connect your accounts.
