Title 26 › 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
Tells you when the tax rules treat certain deals as if you sold an investment that has gone up in value. If you enter into one of these “constructive sale” transactions, you must report and pay tax on the gain as if you actually sold the position at its fair market value on that date, and that gain counts in the tax year that includes that date. Later gains or losses on that position are adjusted for the amount already taxed, and the position’s holding period starts on the constructive sale date. An "appreciated financial position" means a stock, debt, or partnership interest that would show a gain if sold at market value. It does not include some plain debt that pays a fixed principal and qualified interest and is not convertible, hedges of that debt, or positions already marked to market. A "position" means an interest such as a futures or forward contract, a short sale, or an option. You are treated as making a constructive sale when you (or a related person as described in section 267(b) or 707(b) and done to avoid this rule) enter into a short sale, an offsetting notional principal contract, a futures/forward to deliver the same or substantially identical property, acquire the same property when you had a short or similar contract, or other transactions the Treasury says have the same effect. Contracts to sell nonmarketable property that settle within 1 year are not treated as constructive sales. There are also special short-window rules about transactions closed near year end (30 days) and holding the position for 60 days after closing, plus other technical rules about trusts, multiple positions, and how later sales interact. The Treasury may write rules to implement these points.
