The IRS views convertible virtual currency as property, not foreign currency. As such, taxpayers must record and track the tax basis of each unit of virtual currency held in order to property report taxable gain or loss when disposing of a unit or units of virtual currency. This article reviews the IRS’s position with respect to the identification and tax basis of such units.
Taxpayers need to record and track the tax basis of each and every unit of virtual currency they hold in their wallet, account or address to properly report taxable gain or loss each time they dispose of a unit or units. In general, the tax basis of property is its cost (expressed in US dollars) paid to acquire the virtual currency, including any commissions, fees and acquisition costs (I.R.C. § 1012(a).). This article addresses specific identification requirements for dispositions of convertible virtual currency. It starts from the US Internal Revenue Service’s (IRS) view that convertible virtual currency is property. For a discussion of the legal authority of IRS Notices and other pronouncements, see McDermott’s article, “The Legal Effect of IRS Pronouncements on Virtual Currency Taxation.“
IRS Notice 2014-21 (2014-16 I.R.B. 938, Q&A 7) and 2019 Frequently Questions (FAQs; IR-2019-167) set out the IRS’s views with respect to certain aspects of the taxation of convertible virtual currency. The IRS takes the position that virtual currency is property—not foreign currency—for federal tax purposes (Notice 2014-21, Q&As 1 and 2). As such, the IRS reasons, each separate coin, token or unit (collectively, unit) of convertible virtual currency has its own tax basis (Q&A 4). In addition, the tax basis of virtual currency received as payment for goods or services is treated as its fair market value as of the date of receipt (Q&A 3). Tax character of gain or loss from disposing of virtual currency turns on whether the virtual currency is an ordinary or capital asset in the taxpayer’s hands (Q&A 7). The IRS treats purchases made with virtual currency as barter exchanges, which means that both the person receiving units and the person spending units have taxable gain or loss (Q&As 1 and 2).
Why Tax Basis Is Important
Although tracking tax basis on a unit-by-unit basis might be burdensome for some taxpayers and some transactions, it provides taxpayers with an opportunity for significant tax benefits. Taxpayers can pick and choose which units they want to sell. They can select those units with the highest tax basis to minimize their current taxation and push gains into future tax years. Or, they can maximize current taxation by selling those units with the lowest tax basis.
Taxpayers who choose not to identify their units are subject to a default tax basis rule, meaning they will be taxed on the sale of their units on a first–in–first–out basis (FIFO; FAQ, 40).
Average Cost Method Not Available
Taxpayers holding multiple units of a given virtual currency often acquire these units at different times and at different prices. If they sell a portion, but not all, of their units at any given time, they might want to use the average cost method to calculate their gains and losses. The average cost method is mandatory for partnership interests, foreign currency that is the taxpayer’s functional currency and certain corporate transactions. It is elective for taxpayers who hold mutual fund shares. The average cost method allows, for example, electing taxpayers to calculate the value of their mutual fund positions on an aggregate basis to determine their profit or loss. Such electing taxpayers can determine their tax basis by taking the average cost of all of the shares they own in a particular fund and multiplying the average cost by the number of fund shares they are selling. The average cost method can be a simple way to handle mutual fund sales for taxpayers who reinvest their mutual fund dividends and regularly add to their mutual fund holdings (I.R.C.§ 1012(c)(1)). But no US Department of the Treasury or IRS authority allows for the use of the average cost method for virtual currency.
Specifically Identifying Virtual Currency
According to the IRS Notice and FAQs, taxpayers have two ways to identify the basis of their specific units. First, taxpayers can document a specific unit’s unique digital identifier—such as a private key, public key or address. Or, they can record all of the transaction information for the units in a single account, wallet or address (FAQ, 36 and 37).
To comply with specific identification, taxpayers must record the following information:
The date and time each unit was acquired
The basis and fair market value of each unit at the time acquired
The date and time each unit was sold, exchanged or otherwise disposed of
The fair market value of each unit when disposed of
The amount of money or the value of property received for each unit (FAQ, 39).
By maintaining this information, taxpayers can dispose of high basis units first, minimizing their current tax and deferring taxable gains. Specific identification allows taxpayer complete flexibility in selecting the units they want to sell. In fact, taxpayers can replicate any of the possible basis tracking methods, changing their selection criteria as their tax objectives change.
