US Tax Question

Suppose that John Doe mines 100 bitcoin at $0.11 each ($11) and doesn't sell them, but keeps them in a wallet. Does he pay taxes the year he mined them at the price he mined them for, or does he pay taxes on the value he sells them for - like paying taxes on the $10,000 he receives when he sells them for $100 each? And how does the cost of electricity factor into this, since each bitcoin (especially now) costs a lot of money to earn based on the price of electricity?

Based on my research, the answer is both. You would pay taxes on the bitcoin you mine as income, and then capital gains tax when you sell them for a profit (or capital loss if you lose value on the sale).

You can write off a portion of your electricity bill and hardware purchased for the use of mining as a business expense, but it's recommended that you consult a tax professional for determining the proper amount that is eligible for a deduction.

From Forbes:

New Bitcoin are being issued by the system roughly every 10 minutes by a process called mining. In mining, computers running the Bitcoin software around the world attempt to solve math problems and the first computer to come up with the solution adds the most recent transactions to the ledger of all Bitcoin transactions, plus receives the new bitcoins created by the system, called the block reward.

If you are a miner and win the block reward, you must record the fair market value of Bitcoin that day and mark that as an addition to your personal or business income. Also note the date and timestamp at which your coins were mined. Later, when you dispose of those Bitcoin, you will subtract the date of acquisition from the date of disposal, and you will be taxed a long-term capital gains rate on any Bitcoin you held for more than a year, and a short-term capital gains rate on any Bitcoin you held for a year or less. (The timestamp isn’t absolutely necessary, but is helpful to validate the order of multiple acquisitions or disposals within a day.)

The amount you pay in taxes on a long-term capital gain will depend on your income-tax bracket, while short-term capital gains are taxed the same as ordinary income.

From bitcoin.tax:

Another clarification in the IRS's March notice was how mining should be treated. Mining is income, on the day of receipt of any coins and at the fair value of those coins. This means that if you mined any Bitcoins or alt-coins either solo, as part of a pool, or through a cloud provider, you need to report any coins you received as income.

Where it is less clear, is what that dollar value might be, since the fair value is not always as easy to determine.

Bitcoins, Litecoins, Dogecoins, are all examples of where there is a direct USD market and so you can easily find out their value of any given day. However, a newly created alt-coin that was mined in its early days has no direct market and so how do you determine its value? Or for any alt-coin, e.g. ABC coin, that has no direct USD market but does have a BTC market. Does it have a value? Do you have to make a conversion from ABC to BTC to USD?

Since there is no clarification yet from the IRS on this issue you should discuss how to proceed with your own tax professional. BitcoinTaxes has taken a prudent approach and calculates value where a fiat or BTC market exists, converting an alt-coin to BTC to USD as necessary.

And from Bitcoin magazine:

The IRS also stated mined bitcoins are treated as immediate income at the market value of those mined coins on their date of mining.

“Most don’t know they can write off any losses they have,” said Libra founder Jake Benson. “The IRS allows you to offset income by up to $3,000 per year on capital losses. If you have losses and you aren’t writing them off, then it’s like throwing money away. Nobody likes doing taxes, but if you can owe less or increase your return, then doing your Bitcoin taxes often results in a benefit. In fact, the majority of our users are filing a capital loss, which means they’ve actually saved money by using our tool.”

Benson also gives insight for miners.

“Mining is considered income, so know the price of Bitcoin at the time you mined it,” he said. “If you make money on Bitcoin trading, the IRS requires that you report gains with line level detail.” The appropriate form for that is 8949, a sub-form of schedule D. Gains and losses, as outlined above, are treated like every other capital asset.

And directly from IRS notice 2014-21 FAQ:

Q-1: How is virtual currency treated for federal tax purposes?

A-1: For federal tax purposes, virtual currency is treated as property. General tax principles applicable to property transactions apply to transactions using virtual currency.

Q-6: Does a taxpayer have gain or loss upon an exchange of virtual currency for other property?

A-6: Yes. If the fair market value of property received in exchange for virtual currency exceeds the taxpayer’s adjusted basis of the virtual currency, the taxpayer has taxable gain. The taxpayer has a loss if the fair market value of the property received is less than the adjusted basis of the virtual currency.…

Q-8: Does a taxpayer who “mines” virtual currency (for example, uses computer resources to validate Bitcoin transactions and maintain the public Bitcoin transaction ledger) realize gross income upon receipt of the virtual currency resulting from those activities?

A-8: Yes, when a taxpayer successfully “mines” virtual currency, the fair market value of the virtual currency as of the date of receipt is includible in gross income. See Publication 525, Taxable and Nontaxable Income, for more information on taxable income.
