Investments & Capital Gains

Capital gains rates, loss harvesting, crypto taxation, NIIT, QSBS, and charitable giving strategies.

Investment taxation is where planning decisions compound most visibly. The difference between short-term and long-term rates, the wash sale rule, the NIIT surcharge, and the complete absence of wash sale rules for cryptocurrency all create planning opportunities that are impossible to exploit without understanding the mechanics.

§1259 Constructive Sale of Appreciated Positions
Section 1259 complete mechanics. Requires gain recognition when a taxpayer locks in economic gain on an appreciated financial position (AFP) by eliminating both downside risk and upside potential. AFP = position in stock, debt instrument, or partnership interest with built-in gain. Four constructive sale triggers §1259(c)(1): (A) short sale of same or substantially identical property ("short against the box"); (B) offsetting notional principal contract; (C) futures or forward contract to deliver; (D) acquisition where AFP is itself a short position. Consequences §1259(a): gain recognized at FMV on constructive sale date; basis increased by gain; new holding period begins. Only gain recognized, never loss. Closed transaction exception §1259(c)(3): no constructive sale if offsetting position closed within 30 days after year-end AND taxpayer holds AFP unhedged for 60 days after closing. Variable prepaid forward contract (VPFC) planning to retain meaningful upside and avoid constructive sale (Rev. Rul. 2003-7); Anschutz Co. v. Commissioner (135 T.C. 78, 2010) - VPFC plus share lending was a current sale. Related person attribution §1259(c)(4). Enacted by Taxpayer Relief Act of 1997 to kill short-against-the-box deferral.
