How to Calculate Crypto Taxes

Last updated: Thursday, 30 September 2021

Need to know how to calculate your crypto taxes? Your crypto is subject to both Capital Gains Tax and Income Tax - depending on the specific transaction you're making. This means you need to be able to calculate your crypto capital gains and losses, as well as your crypto income, to figure out how much tax you'll pay. Don't worry - both are pretty simple. Let's dive into calculating your crypto taxes.

Crypto Tax 101

A quick reminder on crypto tax before we jump in, there's two types of tax when it comes to crypto - Capital Gains Tax and Income Tax - and you calculate them in different ways.

You'll pay Capital Gains Tax on crypto any time you:

  • Sell crypto for fiat currency - like USD.
  • Trade crypto for crypto.
  • Spend crypto on goods or services.
  • Gift crypto - in most countries.

When is crypto taxed as capital?

Meanwhile you'll pay Income Tax on crypto you 'earn', this includes:

  • Getting paid in crypto - like a salary.
  • Mining crypto.
  • Staking rewards.
  • Referral bonuses.
  • Airdrops.
  • Hard forks.
  • Crypto interest.
  • Many crypto DeFi activities like yield farming and liquidity mining.

When is crypto taxed as income?

This is a general overview. The rules vary per country so make sure to check your country's crypto tax rules in our crypto tax guides to see how it works where you live. You can also learn more about crypto tax in our Crypto Capital Gains Tax Guide and Crypto Income Tax Guide.

Once you've identified which type of tax applies to your crypto transaction(s) - you need to calculate your profit and the amount of tax you'll pay. We'll look at both - starting with crypto income.

How to calculate crypto income

Crypto income is easy to calculate. All you need to do is take the fair market value of the coins or tokens in fiat currency on the day you received them.

So for example, say you mined Bitcoin. You earned 0.1 BTC and you received it on the 5th of January 2022. The price of 0.1 BTC that day was $3,667. So you have $3,667 in crypto income - which you'll pay Income Tax on at your regular rate.

It's that simple. But remember, just because you've paid Income Tax on crypto doesn't mean you won't pay Capital Gains Tax on crypto should you later sell, trade, spend or gift. So let's look at how to calculate crypto capital gains too.

How to calculate crypto capital gains

Whenever you sell, trade, spend or gift crypto - you'll have a capital gain or a capital loss. This is the difference in value between when you acquired your crypto and when you sold, traded, spent or gifted it. If the price has increased, you have a capital gain (profit). If the price has decreased, you have a capital loss.

To calculate a capital gain - you need to start with your cost basis. This is the price you bought the crypto for plus any transaction fees. If you acquired the crypto through other means and don't know the cost basis - use the fair market value of the crypto in fiat currency on the day you received it as your cost basis instead.

Cost basis formula

Once you've got your cost basis, simply subtract it from the price you sold your crypto for to calculate your profit or loss. If you traded, spent or gifted your crypto - subtract it from the fair market value of the crypto in fiat currency on the day you received it instead.

Capital gain formula

Let's carry on with the example we used above. You sold the 0.1 BTC you mined later that month. The price of 0.1 BTC on the day you sold it was $4,200. You need to subtract your cost basis from your sale price. You know the fair market value of your mined BTC on the day you received it was $3,667 so:

$4,200 - $3,667 = $533. You have a capital gain of $533 that you'll need to pay Capital Gains Tax on.

Capital Gains Tax rates vary per country. Some countries have a short-term and long-term Capital Gains Tax rate (like the US), while other countries simply use your Income Tax rate as your Capital Gains Tax rate. Many countries also allow you to earn tax-free capital gains, up to a certain amount each year.

You can check your country's crypto tax guide to find out your crypto Capital Gains Tax rate and Income Tax rates.

Calculating crypto cost basis

So the example we used above actually simplified things. Most crypto investors aren't just mining a small volume of coins and selling one coin a year- otherwise we wouldn't need crypto tax software. So let's look at another example to explain.

You bought 2 ETH in 2020 and the price of ETH that day was $500. You bought another 1 ETH in 2021 for $3,600. You sold 1 ETH in 2022 for $2,400. If you use the cost basis from the ETH you bought in 2020, you have a $1,900 capital gain which you need to pay Capital Gains Tax on. Meanwhile, if you use the cost basis from the ETH you bought in 2021, you've got a $1,200 capital loss. So how do you know which cost basis to use?

You use a cost basis method. We have a whole article on this - but in brief a cost basis method tells you which cost base to use when calculating your capital gains and losses. Some countries - like the UK - have strict rules on cost basis methods, while others let you pick from a variety of cost basis methods to use - like the US.

There are a lot of cost basis formulas to choose from around the world, including:

  • First In, First Out (FIFO): The first asset you buy is the first asset you sell.
  • Last In, First Out (LIFO): Opposite of FIFO, use the cost basis of the asset you purchased most recently.
  • Average Cost Basis (ACB): An average cost for all assets, calculate this by adding up the total amount you paid to buy your asset(s) and divide it by the total amount of coins/tokens held.
  • Highest Cost, First Out (HIFO): Most expensive asset is sold first.
  • Lowest Cost, First Out (LCFO): The least expensive asset is sold first.
  • Specific Lot Identification (Spec ID): Pick which asset you sold using TXN numbers.
  • Loss Gain Utilization (LGUT): Use the cost basis that would result in the largest loss first.

You can find out more about the pros and cons of cost basis methods and which countries allow which cost basis method in our Cost Basis Guide.
