Our verdict

Koinly is a crypto tax management platform with a free tier and 4 paid levels, offering wide coverage of exchanges.

Koinly is pricy, but if you need a platform with support, it’s worth considering. It’s a shame that HMRC doesn’t accept Koinly reports, but that may change in the future.


  • Broad coverage. Koinly covers 6,000+ blockchains, 380+ exchanges and 50+ wallets, so even power users outside the mainstream are likely to find what they need.
  • 14 blockchains are supported with automated data capture, including Bitcoin, Ethereum, Litecoin, NEO and EOS.
  • Available in more than 20 countries, including the US, UK, Australia, New Zealand, Japan, South Korea, Singapore and most European countries.
  • Automated import of transaction data via API.
  • Auto-generation of capital gains summary.
  • Price records going back 5 years, and the option of integrating all your activity in this period.
  • Authentication via Google or Coinbase reduces the chances of a data breach.
  • Free membership tier.


  • Pricier than some of its rivals.
  • The range of options could overwhelm beginners.

Don't invest unless you're prepared to lose all the money you invest. This is a high-risk investment and you should not expect to be protected if something goes wrong. Take 2 mins to learn more.
Crypto is unregulated in the UK; there's no consumer protection; value can rise or fall; tax on profits may apply*.

How does Koinly work?

Koinly’s integrated tax tracking platform is designed to help you pay the correct amount of tax resulting from your crypto transactions. Tax on crypto is evolving in most developed markets. The UK treats gains from selling crypto the same as if you sold gold or property – you can be liable for capital gains tax (CGT). CGT is a tax on the profit you make when you sell an asset that has increased in value. Learn more about it in our crypto tax guide.

Koinly shows you your crypto activity, consolidates it into useful reports and then determines what tax is due. Here’s a brief list of its key functions.

  • Cost basis. The platform defaults to the primary method in your jurisdiction. In the UK, HMRC uses “share pooling rules” to calculate your CGT. These are complex and are designed to stop crypto investors from manipulating their gains by selling and rebuying crypto assets to create an artificial loss.
  • Transfer matching. An AI solution will detect and filter out transfers between your own wallets, which usually don’t need to be taxed.
  • Overall tax reporting. A consolidated report displays all your taxable gains in crypto.
  • Gifts, donations and losses. A separate report displays the transactions you have tagged in these categories, which HMRC treats differently.
  • Income reporting. A single statement shows your income from airdrops, forks, staking, DeFi activities and other transactions that have netted you income.

If you select the UK as your home country during set-up, Koinly is configured to calculate crypto tax in line with HMRC guidance. But it also admits that HMRC does not audit crypto tax software currently, meaning that HMRC will not accept Koinly reports.

Which exchanges does Koinly support in the UK?

Koinly supports around over 400 exchanges, including the following:

  • Coinjar
  • eToro
  • Gemini
  • Kraken
  • Revolut

Using Koinly to log crypto income and gains

If Koinly has highlighted that you’ve achieved either gains beyond your tax-free allowance when selling your crypto or income from crypto at any point in the tax year, then you should report this to HMRC by submitting a self-assessment return as you’ll need to pay tax.

As part of your self-assessment, you need to submit a CGT summary supplement.

How experienced do you need to be with crypto to use Koinly?

One of Koinly’s strengths is that it broadly caters to every experience level. Its various tiers offer a wide range of functionality, segmented by budget and, more relevantly, the range of services you need.

If you need a sophisticated tax solution, you likely have some level of crypto experience, but there are extensive support resources to support newcomers, and the interface is user-friendly.

What cryptocurrencies can I use with Koinly?

Koinly says it supports more than 23,000 cryptocurrencies. It covers every coin listed on CoinMarketCap and every token based on the Ethereum, BSC and Polygon chains.

This means coverage of some obscure coins and tokens is variable. New tokens are automatically added once they start trading on exchanges. You can confirm this on the “Prices” tab on the app, which will have the most up-to-date information.

Is Koinly safe?

Koinly doesn’t need your private key and never asks for direct access to your funds.

It operates via API connections, so if you’re particularly security-conscious and technically-minded, you may want to disable withdrawal and trading functions when you are setting your API configurations.

All connections with the platform are encrypted, and Koinly uses Amazon Web Services (AWS), which has a strong record for security.
