🧮 Best Bitcoin Tax Calculator in the UK

Bitcoin tax calculator

Why would you need a Bitcoin tax calculator? You will need to pay a tax if you have any cryptocurrency you decide to get rid of (sell, present, donate, etc.). Tax payments are required because capital gains and losses rules apply when you dispose of your cryptocurrency.

HMRC explains that disposals include:

  • selling cryptocurrency for cash
  • exchanging cryptocurrency for a different type of cryptocurrency
  • using cryptocurrency to pay for goods or services
  • giving away cryptocurrency to another person

And calculating those crypto taxes can be tricky as they are calculated based on the capital gains or losses from your digital asset holdings of coins like bitcoin. You are taxed on the value your crypto gains between when you acquire it and when you sell or exchange it.

What does it mean? This means you must keep a complete record of your every transaction to do the correct math.

On the other hand, you can use one of the crypto tax calculators that will do "all the dirty work" for you.

How do you handle your crypto tax?

To accurately calculate your tax liability, you must track your tax lots.

What are those lots? Tax lots entail a cost basis (the amount you originally paid for the crypto), time held, and the price at which you sold the crypto. The cryptocurrency tax calculator handles this automatically, using your investment and trading history.

You’ll need your transaction history to track your tax lots. Additionally, for each sale or exchange, you will need the following information:

  • Amount and currency of the coin or token sold
  • Fiat value at the time of acquisition
  • Date of acquisition
  • Fiat value at the time of trade or sale
  • Date of sale

It is essential to keep detailed records because trades are challenging to backfill, and any missing cost basis increases your tax liability.

You can backfill missing data from receipts and exchange transaction confirmation emails, but it is much simpler to back up your information from exchanges regularly. Keeping notes on special situations, such as lost coins and ICOs, will help you fill out your tax forms.

How to use a crypto tax calculator?

A crypto tax calculator is a software that, when linked to your crypto exchange account, will aggregate your data and automatically link your cost basis to your sales. They calculate your gains or losses and automatically populate tax reports with your data.
