BearTax is a clever solution for crypto investors who want to keep up with their tax obligations but don’t want to make a lot of changes to their existing routine. This app lets you use your existing tax reporting software, like TurboTax, to handle your crypto tax obligations. As someone who uses TurboTax for my own taxes every year, I was able to get up and running with BearTax in a matter of minutes.

I've been through the layers. Trading crypto for years now, since back when compliance wasn't really a problem. Been through multiple softwares and the price never justified my fluctuating trade volumes. BearTax was able to customize their offering to my needs, and they're much more cost efficient on my finances. Thank you BearTax, looks like compliance isn't a problem anymore again! You do have to file the actual reports but that's a simple integration and they even helped ease that process for me. Great service!

Kunal Dubey

Love the format and ease of this site -- the streamlined interface and API uploads, the timely customer service, the easy-to-use corrections page, and the great prices! I've used other software, but this one was by far the best - thank you!

Rahani Beugel

I think Fyn is pretty effective! I was kind of surprised by how well the API system worked to update gains and losses. As far as the import option, I had a problem and the online support was quick to accept my spreadsheets...WAAY easier than I thought it would be.

Howard Bonds

Very cost-effective and straightforward to use. Has API integrations with the major players, and supports CSV for all the rest. Nice UI too, and it is really cool to be able to see transaction count and cost/gains summary before purchase -- other places require knowing this all in advance, which is more-or-less the point of the tool in the first place.

Brent Riva

Very easy to use. I had started on another site and was so confused. Fyn was so easy and the customer service was awesome. A few times I was confused and they helped me. At the end I just downloaded to the correct tax form to submit. They have a telegram site that has alot of questions and information on it. I will use it again next year.

Toni Violette

Awesome site! extremely user-friendly, so so helpful, I would be lost without them. I highly suggest using this service for all of your crypto transactions. I can not recommend them enough. Great service friendly people. I will say though that they do not work on weekends so get your work done during the week.

Kevin Riley

Fyn has been amazing. The quick and prompt customer service made the experience even better. Every time I had an issue, someone was there within minutes to clarify and provide proper guidance. I never imagined that kind of support and to be able to see my gains/losses before purchasing. I definitely recommend.

James Dos Santos

This is a very interesting product and definitely helps with account trading and reviews. It is very user friendly and not at all counter -intuitive. So far i see no hidden costs except that it helps you select a payment method depending on the amount of transactions you traded.

Miguel Gomez

Simple and straightforward way to get taxes done!
