Cryptocurrencies have taken the world by storm but for crypto accountants and tax professionals, the storm continues to loom over them in the form of cost basis for calculating cryptocurrency gains and losses. Crypto accounting and tax professionals are already battling the difficult series of unique taxation challenges as new guidance becomes more clear and permanent.


Understanding Cost Basis For Crypto


Cryptocurrency cost basis is similar to traditional “basis”, and is the means of calculating profit and loss of asset value based on a series of assets and their accompanying transactions and costs. To put it plainly, cost basis is equal to the amount of money in fiat currency that an asset costs for an investor to acquire. Because cryptocurrency is a taxable asset, the process of calculating the correct gains and losses requires having the correct basis in place for your crypto portfolio. Essentially, cost basis is an accounting term that refers to purchase price + fees + other purchase costs.


To articulate cost basis more easily, if an investor purchased a Bitcoin in 2015 for $400 the basis on that Bitcoin is $400. If the same investor sold their Bitcoin one-year later for $2000, they would owe taxes based on their gains of $1600. (Let’s exclude the fees & other factors for this example)



By understanding the fundamentals of crypto cost basis, it is important to understand why crypto cost basis is a growing concern and challenge for the industry, tax professionals and even the government and federal institutions.

The IRS Is Providing Crypto Clarity

As of October 2019, the IRS has issued more guidance and clarity on cryptocurrency accounting and taxation than in the last five years. Most crypto investors may not even know that in May 2019, the IRS issued 10,000 letters to known crypto holders warning them to disclose their crypto assets. This was due to record lows in crypto reporting in the USA and around the world.

As of October 2019, the IRS has recently updated its tax forms to include a section that solely focuses on individuals or businesses crypto earnings and assets. Moreover, the IRS issued more clarity on how to handle debated issues such as cost basis techniques, taxation on hard/soft forks, airdrops and more. While most of this news only clarified what taxation professionals already knew, it’s important for investors, new and experienced alike to make more proactive actions when it comes to filing for tax season 2020.


When Manually Calculating Cost Basis

Calculating crypto cost basis can be exceptionally difficult, even for seasoned veteran accounting and taxation professionals. If you ask your traditional accounting CPA, they may not even know where to begin to handle crypto taxation.


When manually calculating your gains and losses, users will need access to their crypto wallets, accounts, portfolios and exchanges and their history of transactions. From there, users would need to find a way to consolidate all their various information, download their transaction history, find a calculator and begin calculating using the FIFO method (First In, First Out). This method is the recommended approach to calculating cost basis, according to the Internal Revenue Service.


Calculating 100 transactions could take days, and one mistake can dramatically affect the final result. This is why today’s crypto companies, mining operations, and blockchain businesses rely on Blox for their crypto accounting and taxation. Technology is available to help streamline the entire process of crypto accounting, tax prep and more.
