Subscription question

Had a question about cancelling and re-starting a subscription in the future, which was very well explained by Gilbert. I have used the product for a couple of years and it is well supported.

The company replied very quickly and Gilbert answered my concerns, although whilst I understand the reasons why certain operations need a manual input, I still believe Crypto Tax Calculator needs to improve areas where automatic calculations would remove the need for manual input. The information is available to do this, yet the company claim they do not have the resources or time to address these areas. That is why I have given 4 stars.

Hi Michael,

Thank you for taking the time to share your feedback. We're really sorry to hear about your experience with our support response time.

We’ve sent a request for more information so we can look into your specific interaction, but we haven’t yet received a response. We'd really like the opportunity to investigate this further and make things right. If you could please respond to that request that would be a great help.

Kind regards,

Quick and easy way to prepare your crypto tax return

I have crypto in different places and some of it is staked, so it would have been a slog to put together my tax return. CTC was the solution for me. It automatically creates a full report for my tax jurisdiction - amazingly quick and easy to use. It certainly pays for itself with your first return. Highly recommended.

Simple yet effective, great customer service

Really like this product. Tried Koinly, CoinStats and Cointracker for both crypto portfolio and tax. Found CTC the best by far, had no issues with API integration to my wallets and exchanges and had it all setup in 10 mins. It also got all my dex transactions correct, which Koinly did not...bloody nightmare. CTC was also the only product that correctly calculated the average cost for each coin type.

Recently there was an issue with the Swyftx API (on the Swyftx side) and CTC responded quickly and checked things there end. They also lodged a fault with Swyftx and put up an advisement in their portal that Swyftx had an issue with their API. On that note, Swyftx were very good with their support as well.

I'm yet to do my tax but so far I'm confident this product will deliver.

User friendly Crypto Tax Platform

Excellent user friendly platform to work for those who trade crypto currencies in multiple exchanges. Great tool to use during tax time to compute the capital gains/losses along with a portfolio tracking dashboard. Supports many reputable exchanges worldwide wide.

Crypto Tax Calculator has been a great…

Crypto Tax Calculator has been a great application to manage the variety of crypto related transcations seemlessly. This is very plug and play type of applications supported by AI categrozing the transactions, and most importanly the transcations that are too complicated to be cateorized by default are helped by the wonderful staff. I am throughly blessed to work with Vivi from support staff from last 2 years and she is beyond amazing I cannot recommend her more than enough, she is great and she is what and others make Crypto Tax Calculator application really great!! Thanks

Great Support team

While the issue I had with CTC not updating reports from the data set was slow to fix and caused setbacks with client work, my case support worker, Chris, was fabulous. We worked through many areas to determine what the error was and then it was up to the programming team to remedy the situation. After using CTC for the past 3 odd years, this is the first system issue I have had. As an overall, this product is easy to use, and the team is always quick to assist with queries.

CTC is the best choice

Of all the different services available out there, CTC was the only offering that included everything i needed to properly and easily track my various wallets. And, their customer service is great!

I've been using their site for 4 years now and am happy with the service. They had L2s before all the others, and they had a solution for per wallet and exchange ready pretty fast. I had some difficulty switching over from universal wallet accounting to per wallet and exchange accounting, and was glad that the support team was able to help me sort out all of the issues. Shout out to Arjay and especially Vivi for all their help!
