Title 26 › Subtitle Subtitle A— Income Taxes › Chapter 1— NORMAL TAXES AND SURTAXES › Subchapter P— Capital Gains and Losses › Part IV— SPECIAL RULES FOR DETERMINING CAPITAL GAINS AND LOSSES › § 1259
Treats certain deals as if you sold an investment that went up in value. If you enter one of the listed transactions, you must report any gain right away as if you sold the position at its fair market value on that date. Later gains or losses are adjusted so you do not count the same gain twice, and your holding period for the position starts on that date. An "appreciated financial position" means a stake in stock, debt, or a partnership that would show a gain if sold at market value. It does not include certain plain-vanilla debt that pays fixed principal and interest and is not convertible, hedges of that debt, or positions already marked to market. You are treated as making a constructive sale when you do things like enter a short sale, an offsetting notional principal contract, or a futures or forward contract to deliver the same or a substantially identical item, or when you acquire the same item after having a short or similar contract. A contract to sell a non-marketable security that settles within one year is not treated as a constructive sale. Transactions closed by the 30th day after the tax year end can be ignored if you hold the position for the following 60 days and your risk of loss is not reduced. "Position," "forward contract," and "offsetting notional principal contract" are defined in simple terms, and the Treasury may issue rules to carry out these points.
