Under the IRS ruling, Bitcoin investors would be treated like stock investors. Bitcoins held for more than a year and then sold would pay the lower tax rates applicable to capital gains -- a maximum of 23.8 percent compared with the 43.4 percent top rate on property sold within a year of purchase.
For investors with losses, U.S. tax law allows taxpayers to subtract capital losses from any capital gains. They can also subtract up to $3,000 of capital losses a year from ordinary income.
As with stocks, Bitcoin dealers would be subject to different rules that wouldn’t allow for capital gains treatment.
