Using Bitcoin To Buy A Sandwich Could Trigger A Tax Bill

Crypto currencies may have been around for less than a decade, but they are proliferating so quickly that our established tax and regulatory systems can’t keep up. And that could create serious tax problems for those who would join the digital currency revolution.

The total market value of the crypto currency market rose to over $177 billion in the third quarter of 2017. Crypto currencies are no longer just an adventurous and futuristic investment opportunity; they are making over-night millionaires and rapidly becoming an alternative payment method for everyday goods and services. For example, major companies like Microsoft, DISH Network,, and at least one Subway sandwich shop accept Bitcoin for payment.

But crypto currencies are not like real dollars. The IRS considers crypto currencies to be a form of property, which means that every crypto currency transaction, no matter how small, triggers a separate tax gain or loss. So, the seemingly casual nature in which one might exchange Bitcoins or other virtual currencies for everyday items could leave users and businesses with untold tax liabilities and a record-keeping nightmare, depending on the frequency with which they are used.

Here’s how it works. For tax purposes, a bitcoin is treated as a piece of property, like a diamond. Of course, anyone who receives a bitcoin in exchange for a good or service has taxable income. What is less obvious is that anyone who uses bitcoin to pay for a good or service also can have taxable gain or loss.

For example, if you trade a piece of bitcoin to Subway in exchange for a sandwich, you have a tax realization event, meaning the IRS treats the transaction as if you sold the bitcoin for the sandwich. When you sell property, you have a tax gain or loss measured by the difference between your basis, or what you paid for the property, and the amount you received on the sale of the property.

Any gains realized by a person buying something with a crypto currency are taxable and must be reported to the IRS. And, under the logic of the Internal Revenue Code, any losses may not be deductible if the transaction was personal in nature. Only losses on transactions entered into for profit or in the course of a trade or business are deductible.

The use of Bitcoin in a routine transaction, such as grabbing lunch, buying a couch online, booking a hotel room, or paying for a massage or other service constitutes a taxable transaction that must be tracked and reported to the IRS at the end of the year on your tax return. It is easy to see how an enthusiastic user of bitcoin could have a hundred or more taxable transactions to report at the end of the year. The recordkeeping requirements, which are necessary to prove the amount of each gain or loss on every single transaction, are a nightmare.

Early-adopters of crypto currency decried the IRS announcement that crypto currencies would be subject to tax as if they were exchanges of property. Their claims that overregulation and taxation of the nascent crypto currency ecosystem overburden and stifle the development and growth of this revolutionary new technology are not wrong. At the same time, it is not at all realistic to believe that the multi-billion dollar market in crypto currencies could, or even should, escape the attention of the tax man.

Many people are drawn to Bitcoin, or other “decentralized” crypto currencies, because they believe it allows them conduct transactions anonymously. And some have relied on that sense of anonymity to use crypto currencies to engage in illegal transactions. Unfortunately for them, however, bitcoin and other crypto currencies are not anonymous. The IRS has developed block chain tracking technology that allows them to ferret out users despite the reputed anonymity that Bitcoin addresses provide.

As Bitcoin’s own website explains, “All Bitcoin transactions are stored publicly and permanently on the network, which means anyone can see the balance and transactions of any Bitcoin address.” Indeed, using cash still offers more anonymity than a digital currency.

Recently, the IRS has gotten more serious about ferreting out bitcoin holders who are not reporting and paying their taxes. Just last year, the Justice Department filed a court petition to access the identities of Bitcoin traders who use the crypto currency trading platform, Coinbase. As part of that petition, the department cited the high likelihood that Bitcoin users were evading their tax liabilities. This case illustrates how the IRS still considers the use and acceptance of crypto currencies as a potential red flag that illegal activity is taking place.

Fortunately, there may be some relief in sight for those who wish to incorporate crypto currencies into their everyday lives. Just last month, Reps. Dave Schweikert (R-Ariz.) and Jared Polis (D-Colo.) introduced legislation to make relatively small dollar crypto currency transactions — up to a value of $600 U.S. dollars — tax-free. This means that people could engage in as many crypto currency transactions as they want — and there would be no obligation to track, report or pay tax on the transactions — as long as each transaction stays under the $600 threshold. Larger transactions that exceed $600 would have to be reported to the IRS.

A law like this would be an unusual amendment to the Internal Revenue Code because there are very few de minimus exceptions in the tax law. Typically, gains and losses are taxable no matter how small because a large volume of small transactions can ultimately add up to a large amount of money.

Regardless of how unusual the new legislation may be, it is an excellent idea because it strikes an appropriate balance between the need to regulate and tax crypto currencies on the one hand and the need to provide the space and freedom for technologies like crypto currencies to grow and potentially change our everyday lives on the other hand.

The new legislation will go a long way toward relieving the tax anxiety of enthusiastic crypto currency users. However, as is often the case with our famously complex tax code, there can be unintended consequences. If the bottom suddenly drops out of the bitcoin market and millions of bitcoin holders are left with losses on their investment, they may long for the day when every bitcoin transaction could have generated a tax-saving loss deduction!
