Using the calculator to estimate how much crypto tax you owe
The way you earn your crypto profits affects the type of tax you need to pay, so you’ll start by entering a breakdown of each activity. You’ll normally need to pay Capital Gains Tax on the profits you get from trading, and Income Tax on mining and staking – but it all depends on the total amount you make in a year. For example, you might not pay any Income Tax on the first £12,570 you get each year if you’re entitled to the full amount of your tax-free Personal Allowance.
The calculator estimates how much crypto tax you owe, taking into account any other income you declare. You’ll also be able to enter the details of any crypto-related expenses because you can offset these against your tax bill. This is just an estimate, so always take advice!
We wrote an article which explains how crypto tax is worked out in more detail.
How do I pay crypto tax?
You might be able to use the Capital Gains Tax real time service if you only need to tell HMRC about Capital Gains. Otherwise, you’ll need to sign up for Self Assessment and submit a tax return to report your crypto earnings, with separate sections for Income Tax and Capital Gains Tax. Keeping good records will help you report everything accurately!
If you handle all your crypto through your own limited company, you’ll need to include the details on its Company Tax Return.
FAQs
No, you won’t be taxed on crypto you move from one wallet to another as long as they’re both in your name.
The kind of tax you pay depends on how you make money from crypto. Trading and mining profits are usually subject to Capital Gains Tax, but you’ll pay Income Tax on any profits you make from staking.
Capital Gains Tax is sometimes payable if you ‘dispose’ of an asset and it’s increased in value. A disposal might mean that you sold it, but it can also mean you gave it away, or were compensated for its loss in some way. Income tax is charged on income you receive, such as a salary or payment for providing services.
Our crypto tax tool uses the details of any other income you receive to work out your tax band. This is so it can estimate the tax you’ll need to pay on your crypto more accurately.
You may be able to deduct some of your costs, such as transaction fees, when working out how much you owe, and pay tax on the profit or ‘gain’ left over. The rules around this can be quite complicated, so it’s well worth chatting to your accountant first!
This depends on how you earn crypto. You won’t normally need to pay National Insurance on the gain you get from trading crypto, but if you need to pay Income Tax on mining and staking, then you’ll probably need to consider NI too.
