What if Bitcoin and other Virtual Currencies were Treated as Currencies for U.S. Tax Purposes?

Author: David J. Shakow, Professor Emeritus, University of Pennsylvania School of Law1
The discussion in this document reflects legal principles as of January 20, 2020.

In 2014, in its first decision relating to the cryptocurrencies, the IRS held that a cryptocurrency, such as  Bitcoin, is not a currency for tax purposes. Why was that important? The Internal Revenue Code  contains special provisions relating to currencies. Treating a medium of exchange as a currency provides  some special rules relating to the character and timing of any gain or loss on that item. It also allows  individuals, who may be traveling in a foreign country, to ignore small amounts of gains and losses that  result from changes in exchange rates between the time a unit of currency is purchased and the time it  is spent.  

However, the most important advantage in treating a medium of exchange as a currency is that it allows  a business to conduct its operations in that medium of exchange without having to treat every  transaction in the medium of exchange as a taxable event. If we use the case of Bitcoin, for example, if  bitcoins were treated as a currency for tax purposes, a business that conducts many of its transactions  using bitcoins could keep its books in bitcoins, figure its income or loss at the end of the year in bitcoins,  and only then translate its profit or loss into dollars for purposes of paying its United States tax liability.  The alternative is to calculate gain and loss on every receipt and disposition of a bitcoin. As a practical  matter, this is not possible for a company that has many Bitcoin transactions. The only practical  alternative for such a business is to exchange any bitcoin immediately for cash upon receipt.  

Why did the IRS rule that a cryptocurrency is not a currency? The IRS was interpreting a statute that was  drafted long before cryptocurrencies were a practical alternative to fiat currencies. Apparently, the IRS  thought it would be difficult to interpret the term “currency” in the Internal Revenue Code to  encompass a type of currency unknown when the statute was passed.  

Could this result change? To the extent the IRS’s 2014 notice gave any reason for its conclusion, it stated  that virtual currency does not have “legal tender” status in any jurisdiction. In other words, in no  jurisdiction are persons required to accept any cryptocurrency in payment of an obligation.  

At the moment, this conclusion still holds. There is an exception for a cryptocurrency issued in Venezuela, but even if that cryptocurrency is actually treated as legal tender in Venezuela, it is not a  very significant item of cryptocurrency even within the country.  

However, this situation could change. If any country were to designate Bitcoin, for example, as legal  tender, it would seem that the IRS would change its conclusion and treat Bitcoin as a currency for  purposes of the Internal Revenue Code. However, this result is not strictly compelled, since the nature  of the IRS’s original pronouncement in this area was a “Notice”, a document that does not necessarily  reflect the highest level of review at the IRS. The IRS would most likely treat a cryptocurrency like Bitcoin as a currency for tax purposes if the jurisdiction that accepted it as legal tender were a significant  jurisdiction. If it were a very small jurisdiction (for example, Bhutan, with a population of less than one  million), it is possible that the IRS would withhold its approval. For example, the IRS might distinguish  bitcoins from other items treated as legal tender because unlike other items treated as legal tender,  bitcoins are not issued by a government. However, without further arguments from the IRS, this would  appear to be a distinction without a difference. Accordingly, if a country that was a significant economic  player made Bitcoin legal tender, logic dictates that the IRS should change its position and treat it as a  currency.  

It is not clear currently whether any country will treat a cryptocurrency as legal tender. China, which is  active in the blockchain arena, has announced that it will issue a blockchain version of its currency, the  Yuan. This virtual version will be issued by the Chinese government and is intended to be the exact  equivalent of its regular currency. As such, it can be treated as a currency for tax purposes and does not  raise any new issues in this area.  

So-called stablecoins might be viewed as similar to the blockchain Yuan that the Chinese government is  implementing. A stablecoin is backed by assets and its value is pegged to the assets that back it. So, in  particular, a stablecoin could be backed by a fiat currency and its value would generally equal the  currency that backs it. However, if the stablecoin is not issued by a government and is not accepted by a  government as legal tender, its position for tax purposes would be no different than any other  cryptocurrency.  

An intermediate situation might raise an interesting problem for tax authorities. What if Bitcoin truly  became generally accepted as a form of payment although no jurisdiction officially designated it as legal  tender? There would certainly be a reasonable argument that the IRS’s conclusion should change under  those facts. However, if that were to happen, and Bitcoin became generally accepted, it seems more  likely that any change would be made at the legislative level rather than administratively.
