The USA taxation of Bitcoin

The IRS answered some common questions about the tax treatment of Bitcoin transactions.

Tax treatment depends on how Bitcoin are held and used.

Bitcoin used to pay for goods and services taxed as income.

If you are an employer paying with Bitcoin, you must report employee earnings to the IRS on W-2 forms.

You must convert the Bitcoin value to U.S. dollars as of the date each payment is made and keep careful records.

Wages paid in virtual currency are subject to withholding to the same extent as dollar wages.
Employees must report their total W-2 wages in dollars, even if earned as Bitcoin. Self-employed individuals with Bitcoin gains or losses from sales transactions also must convert the virtual currency to dollars as of the day earned, and report the figures on their tax returns.

Bitcoins held as capital assets are taxed as property.

If you hold Bitcoins as a capital asset, you must treat them as property for tax purposes. General tax principles applicable to property transactions apply.

If the Bitcoins are held as a capital asset, like stocks or bonds, any gain or loss from the sale or exchange of the asset is taxed as a capital gain or loss. Otherwise, the investor realizes ordinary gain or loss on an exchange.

Bitcoin miners must report receipt of the virtual currency as income.

Some people "mine" Bitcoins by using computer resources to validate Bitcoin transactions and maintain the public Bitcoin transaction ledger.

According to the IRS, when a taxpayer successfully “mines” Bitcoins and has earnings from that activity whether in the form of Bitcoins or any other form, he or she must include it in his gross income after determining the fair market dollar value of the virtual currency as of the day he received it. If a Bitcoin miner is self-employed, his or her gross earnings minus allowable tax deductions are also subject to the self-employment tax.
