good customer service + user experience

Only just downloaded so going through the pain of reconciling transactions that comes with any onchain trading at tax time, but great customer service experience. Instant response from an actual human (Karl), who patiently went back and forth with me for 2 days until we figured out the issue. Also really like the interface + features so far, have used Koinly previously.

Best tax guide software

Best tax guide software. Always being updated. Easy to use and anyone can do it. If you need support, the staff is wonderful. Karl never gave up on me and solved any problems I’ve had. I’m a 4+ year user now !

Absoulutely fantastic customer service

Absoulutely fantastic customer service. On a Saturday morning, I had a conversation with a real human across a number of hours helping to resolve some issues. There is an AI assistant that was helpful up to a point, but readily handed off to a human when it was out of it's depth. And the human back up was VERY helpful and responsive. I had a couple of issues over a number of hours and the response time and help given blew me away.

One of the best

First off, its an amazing wallet tracking app. Easy to use, great UI and pleasing to the eyes. Whats more impressive tho is how responsive their support team is. They instantly clarified an issue i encountered and made sure i had all the info moving forward. Great service all throughout!

Karl in tech support really helps when you need it. Navigating crypto investments for a newbie can be difficult especially when unfamiliar with all the taxing requirements to be met when you do your taxes. Crypto Tax Calculator has made keeping track of my crypto investments and tax requirements a lot simpler than I thought it would be. It also really helps to have support when you get stuck and they are great to work with. Highly recommend.

Saved me thousands of dollars!!

I’ve saved thousands on my tax return using Crypto Tax Calculator. After comparing a few competitors, what made CTC stand out was the customer service -quick, knowledgeable, and actually helpful plus the accuracy and depth of the reports. A game changer compared to trying to do this myself in spreadsheets!I thought the pricing was steep, but it's easy to justify the spend given the thousands I saved. Plus the subsciriton is tax deductible, so in reality, it's like 30% cheaper.The product felt a bit overwhelming at first, but after a short learning curve it clicked, with the help of some light touch support. In a side‑by‑side comparison, other platforms treated certain movements as disposals, triggering CGT. CTC correctly recognised them as transfers to my own wallet, which prevented a massive tax overpayment. For me, this is what set it apart. The focus on accuracy is their thing.Overall, reliable, accurate, and worth it for anyone with complex crypto activity.

Had a glitch in the system when upgrading my plan, mostly my fault I think bc after I upgraded I accidentally cancelled my old plan. Anyway couldn't access the site do I sought assistance from CTC support team, was good to get support from human being in a reasonable time frame. They locked in on the task, followed up continuously until the problem was resolved. Good work. Thanks

Used to be good - now too expensive for what I use it

I used to find it practical to quickly draw summaries of my three crypto exchanges for tax purposesFor some reason they add transactions each year, now that would have pushed me to trader plan for USD 499(wtf) without having any more trades than before.For me no longer worth the money just for tax statements.
