How to handle bitcoin gains on your taxes

When you file your taxes this year, your accountant might ask if you own any bitcoin.

The popular digital currency recently hit an all-time high of $1,327 per coin, and while there arguably still hasn’t been a “killer app” (a mainstream purpose for a layperson to use bitcoin), its main use right now is as a speculative investment—and it has been a good investment.

And if you’ve bought something using bitcoin, or sold something for bitcoin, or traded bitcoin for fiat currency, you should consider making that clear on your taxes.

“This is the first year I’ve asked about it,” says Mark Stafford, a CPA in Maryland. “I had one client try to be a miner last year and I realized it was possible that clients were involved and might not think to tell me.”

Believe it or not, the IRS posted official language on digital currency back in 2014; it considers bitcoin to be property. “For federal tax purposes,” the IRS says in no uncertain terms, “virtual currency is treated as property. General tax principles applicable to property transactions apply to transactions using virtual currency.”

If you’ve bought bitcoin simply to hold it as a speculative investment, you don’t need to disclose anything. But as with stocks, income from the sale of bitcoin would be taxed as capital gains, based on the value of bitcoin at the time you sold it. The same goes for if you receive bitcoin as payment, the IRS says: “A taxpayer who receives virtual currency as payment for goods or services must, in computing gross income, include the fair market value of the virtual currency, measured in US dollars.”

There were a number of ways the IRS could have classified bitcoin. It could have labeled it as currency, or a commodity, or a security or debt instrument, as corporate tax attorney Bob Derber has written at the web site of digital currency research group Coin Center. “Bitcoin has qualities resembling all of these property forms, yet it does not neatly fit any of them,” Derber wrote. “Had the IRS treated bitcoin as a currency, special tax rules would have applied to its use and ownership.”

By labeling it property, a bitcoin-for-goods transaction is almost like bartering. If you sell your car for bitcoin, the IRS is saying, it’s property for property, rather than currency for property, which is treated differently.

By not labeling it a currency, bitcoin does not generate a foreign currency gain or loss for tax purposes. That’s surprising, since so much bitcoin is purchased from international exchanges. On the other hand, you can’t physically hold bitcoins, so as Derber puts it, “We’re still not exactly sure how to define where the bitcoin exists.”
