Accountant CSV for Future
Our comprehensive auditable CSV contains the information necessary to trace any taxable transaction done in a specific tax year.
Fyn 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 Fyn 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. Fyn was able to customize their offering to my needs, and they're much more cost efficient on my finances. Thank you Fyn, 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!

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.

Simple and straightforward way to get taxes done!

What is Fyn and how can it help me with cryptocurrency taxes?
Fyn is a software solution that enables individuals, CPAs, and Accounting Firms to calculate the performance of their crypto investments for tax reporting purposes in a given tax year.
What information is included in the forms provided with my subscription?
Tax documents vary by country. Auto-populated tax documents needed by tax authorities have pretty standard columns. The auditable CSV that you can save for your records or provide to an accountant contains the following information: - Asset - Bought on - Cost Basis - Sold on - Total Proceeds - Net Gain/Loss - Short/Long Term
Do you recommend uploading a CSV or to connect an API?
When available, we always recommend connecting via API instead of using a CSV upload. This is because you can import your deposits, transactions, and withdrawals in one go for most exchanges — instead of having to upload multiple CSV files. If an exchange doesn't support API access, you will need to upload CSV files with your transaction data.
How secure is Fyn?
With OAuth or API keys, you are granting our platform with READ ACCESS only. We also do not store your access token or API keys anywhere within our database. This ensures that your data remains secure.
Is it secure for me to grant API access to Fyn?
APIs provide third-party applications the ability to interact with your exchange. Because you are only granting READ ACCESS, there's no way we or anyone else can modify anything on your exchange account. We will never store your API keys and use them only for establishing a one-time connection to fetch your transaction history from the exchange. If the connection ever drops, we'll ask you to provide the API credentials to us again.
