Absolutely worth it !
Absolutely worth it !
I've been using Koinly for multiple years and finally upgraded to a paid plan this year. After importing data from multiple accounts, I managed to clean years of crypto history, including some complex staking rewards, swaps and missing cost basis issues.
The support team (special thanks to Aria and Jack and Will!) went above and beyond, quick, human, and helpful. The tax reports matched TAX requirements perfectly, and the carry-forward losses were handled flawlessly.
After a lot of cleanup, my taxes are 100% reconciled, exactly what I needed. Great product, great people.

Koinly is the best, look no further!
I have two accounting degrees and believe I have tried and compared virtually all the competitor platforms on the market. Though there is a learning curve, Koinly is by far the best and most user-friendly crypto tax software. In additon, customer service has always been stellar! I can't recommend Koinly enough. Crypto transactions can be complex. If you are not familiar with how transactions are handled, take time to read the helpful articles Koinly provides, and do not be afraid to reach out to them to ask questions. Once you are familiar with how things work, getting your tax reports through Koinly should be a breeze!

My Professional Crypto Tax Consultant
I started investing in Crypto since 10years ago but the last 5 years were sleepless nights for me after crypro taxation comes into the picture. Never comes into Crypto investors' mind that we need to declare and file our income. That's where Koinly comes into our rescue. The smart and efficient system, not forgetting the professional assistance from the support team I am now confident that my book keeping is in order. All thanks to Koinly.
