How to Do Your Coinbase Taxes - Why Coinbase Can’t Provide Accurate Tax Information to Users

Coinbase has grown to be one of the largest and most prominently used cryptocurrency exchanges in the world. As of this writing, Coinbase boasts more than 25 million users on its platform. As impressive as this stat is, it comes as a bit of a shock that when it comes to Coinbase taxes, the exchange is unable to provide accurate documentation to many of these users. This article explains why Coinbase taxes are so problematic for users and also discusses how you should properly report your Coinbase crypto transactions on your taxes.

Cryptocurrency Exchanges

Cryptocurrency exchanges like Coinbase make it easy for everyday consumers to buy and sell cryptocurrencies. By nature of the technology that these exchanges operate on (blockchain), users are able to send Bitcoin and other cryptocurrencies to wallet addresses outside of their own network. An example of this would look like you buying Bitcoin through Coinbase and then sending it to a Binance wallet address to acquire new coins and assets on Binance that Coinbase does not offer.

Being able to send cryptocurrencies to other locations and other wallet addresses is core to the whole premise of crypto. However, this core principle is also the culprit behind the massive Coinbase tax problem.

A quick rundown of how the IRS treats cryptocurrency for tax purposes in the US

The IRS treats cryptocurrencies as property for tax purposes. Just like other forms of property—stocks, bonds, real estate—you incur a tax liability when you sell cryptocurrency for more than you acquired it for.

In this sense, cryptocurrency trading looks similar to trading stocks for tax purposes.

For example, if you purchased 0.1 Bitcoin for $1000 in April of 2018 and then sold it two months later for $2,000, you have a $1,000 capital gain. You report this gain on your tax return, and depending on what tax bracket you fall under, you will pay a certain percentage of tax on the gain. Rates fluctuate based on your tax bracket as well as depending on if it was a short term vs. a long term gain.  

On the flip side, if you sold your cryptocurrency for less than you acquired it for, you can write off that capital loss to save money on your crypto taxes.

Why can’t Coinbase provide me with my required tax reports?

To fully understand this problem, you need to understand how capital gains and losses are calculated. To calculate your gains/ losses, you simply apply this formula:

Fair Market Value - Cost Basis = Capital Gain / Loss

What is Cost Basis?

Cost Basis is the original value of an asset for tax purposes. In the world of crypto, your cost basis is essentially how much it cost you to acquire the coin. Sticking with our Coinbase example, if you paid $1,000 to acquire 0.1 Bitcoin on Coinbase, your cost basis is $1000 for that Bitcoin.

What is Fair Market Value?

Fair market value is just how much an asset would sell for on the open market. Again with cryptocurrency, this fair market value is how much the coin was worth in terms of US dollars at the time of the sale. So if I sold that same Bitcoin on Coinbase for $2,000, that would be my fair market value.

Using the formula, you can see that in this case, you have a $1,000 capital gain.

$2,000 - $1,000 = $1,000 gain

The Coinbase Tax Problem

So here’s the huge problem: Because you can send cryptocurrencies from other platforms into Coinbase at any time, Coinbase has no possible way of knowing how, when, where, or at what cost you acquired that cryptocurrency that you sent in. Coinbase only sees that it showed up in your coinbase wallet.

This means that anytime you move crypto assets off of Coinbase or into Coinbase from another location, Coinbase completely loses the ability to provide you with accurate tax information. This is because it has no way of identifying what your cost basis is in that certain cryptocurrency which is an ESSENTIAL piece to figure out your capital gain or loss.

As you can see pictured below, Coinbase explains to their users themselves that their generated tax reports won’t be accurate if you have done any of the following: Bought or sold digital assets on another exchange, sent or received digital assets from a non-Coinbase wallet, sent or received digital assets from another exchange including Coinbase Pro, stored digital assets on an external storage device, or participated in an ICO.

That’s a lot of exclusions, and it accounts for millions of Coinbase users that are left in a difficult position when it comes to accurately reporting taxes.

The Bigger Problem

As you may have guessed, this doesn’t affect just Coinbase. Every cryptocurrency exchange out there that allows users to send and receive cryptocurrencies from other platforms (essentially all of them) faces this exact same problem.

This means that millions of cryptocurrency users cannot rely on their exchanges to provide them with accurate tax reports. It is simply impossible for the exchange to do so.

Maybe you’ve seen all of the frantic posts on the internet of cryptocurrency exchange users freaking out because of the tax reports they tried to generate from Coinbase and other exchanges and how completely inaccurate they are.

So if Coinbase can't give me my needed tax reports, how do I get them?

To properly build out your necessary crypto tax forms and solve the cryptocurrency tax problem, you need to pull together all of your cryptocurrency data that makes up your buys, sells, trades, air drops, forks, mined coins, exchanges, and swaps across all exchanges that you use. Once you have all of your cryptocurrency data in one unit of record, then you will be able to carry out the necessary capital gains and losses calculations.

You can do this by hand by exporting all of your trade history files from your exchanges and doing the capital gains and losses calculations for each trade. Each tax event should be recorded on form 8949 and your net gain should be transferred onto your 1040 schedule D. We walk through the manual reporting process in our article here: how to report cryptocurrency on taxes.
