As someone who mainly buys and holds crypto with under 100 transactions, Koinly has been a fantastic tool. It was super easy to set up — I connected my exchange accounts and wallets in minutes, and Koinly handled all the calculations automatically.

I have just started using Koinly, and had a few questions about their services and yearly plans. I spoke with CARL from the Koinly support team, and he answered all the questions I had, and provided me with the exact solutions I needed! Carl was so kind, responded quickly and really cared about me as a customer. Thank you so much - Absolutely 5 stars!!
I can not emphasise how amazing this service is. Knowing that Koinly will accurately and seamlessly calculate your capital gains (even taking into account trading/transfer fees, exchange rates, order splitting etc), gives me the strength, confidence and power to make the some bold and courageous moves in the market that have really paid off and will continue to do so for the rest of my life. Thank you Koinly
Quick response and resolution to my issue as usual. Great support team,
I've been using Koinly for 5 years now. The price is fair and I've found no reason to look elsewhere for my crypto tracking needs. For a very complex Crypto ecosystem, Koinly strikes the right balance of flexibility and ease of use. It handles everyday trades and transfers automatically but also handles most of my more complex items like defi token delegation and staking.
Crypto taxes can be a massive headache. Koinly and the support team have provided continued help for me in the 5 years I have been using them. Highly recommend!
Customer service is great and help me get through this tax season.
Outstanding, especially the "Expert Review" service. Makes crypto tax a breeze.
I had an issue with some USDC reported as $0 cost basis. I tried for hours to track it down and fix it but could not figure it out. I contacted support and within 24 hrs their AI had found the problem and corrected it. Part of it was related to time stamps. The AI also found and attempt by me to modify a transaction, which I did incorrectly, so it corrected that as well. Pretty amazing.
Navigating the world of crypto tax in the UK can feel like a minefield, but Koinly has truly been a lifesaver. As a UK crypto investor, the specific rules set by HMRC—like the Share Pooling method, same-day rule, and bed-and-breakfasting rules—can be incredibly complex to manage manually. Koinly takes all the stress out of it. From the moment I connected my wallets and exchanges, the platform's ability to automatically sync transactions was a game-changer. It accurately pulls in all my trading history, including DeFi, staking rewards, and NFTs, and correctly identifies transfers between my own wallets. This is a huge time-saver and drastically reduces the risk of human error. What I appreciate most is how Koinly handles the UK's unique tax requirements. It automatically applies the correct cost-basis method and provides an HMRC-compliant report that's easy to understand. The report provides a clear breakdown of my capital gains and losses, as well as any income from crypto, so I know exactly what to declare on my Self Assessment tax return. The user interface is intuitive, and the dashboard gives a real-time view of my portfolio's performance and tax liability. It even helps with tax-loss harvesting by showing me where I can offset gains. For anyone in the UK who has ever dreaded tax season because of their crypto activity, Koinly is the solution. It's accurate, reliable, and gives me the confidence to file my taxes correctly and confidently. I can't recommend it enough.
Couple things: 1. Seamless, intuitive and straightforward to go from go to wowe. Setting up was a breeze, and each of the things I’ve needed to do. Easy peasy, lemon squeezy. 2. Basics / obligatory items done brilliantly e.g. tax reporting. 3. It’s become my new portfolio management tool. Soooo much more than point 2. This thing allows me to view all our Crypto from every angle - regardless of actual wallet. Aggregating by coin - across wallets, etc is the business!! This thing’s the real deal! And you don’t even have to pay for that functionality…only when you want / need to do the (point 2.) tax reporting. 4. Handy as for SMSF!!! Something I had been stressing about, just became a whole lot easier and the stress just melted away.
It was super easy to use their interface The auto connection to my wallet was very simple intuitive and the most important thing is that it saved me a lot of time and effort
I have been using it for years now. Smooth and easy to navigate.
Using Koinly made my tax time super easy, it removed all of the stress out of calculating the numbers, and the worry of if it was correct or not. Would definitely recommend Koinly.
Absolutely amazing app that not only is easy to use, but saves me loads of time and stress. Highly recommneded and I've been a keen user for years.
Easy process and hassle-free crypto tax filing.
