Tax Loss Harvesting Definition: Tax Loss Harvesting is the strategic practice of selling investments at a loss to offset capital gains taxes — using realized losses to reduce taxable gains plus up to $3,000 of ordinary income annually under US IRS rules — with excess losses carried forward indefinitely. Major US wash sale rule (IRC Section 1091) prevents repurchase within 30 days before or after sale; violation disallows the loss deduction. Major typical robo-advisors automate: Wealthfront (since 2014), Betterment, Schwab Intelligent Portfolios, with 2022 a record harvesting year (S&P -19%, bonds -13%). Major crypto exempt from wash sale rule as of 2024 (loophole, may close).
What Is Tax Loss Harvesting?
Tax Loss Harvesting represents one of investment tax planning’s most consequential strategies, fundamentally reducing tax liabilities legally. Where buy-and-hold ignores taxes, harvesting captures losses. The framework affects markets through: year-end selling pressure (December tax-loss selling), January Effect (recovery), robo-advisor automation, ETF substitution flows, and behavioral tax-planning. Major characteristics include: realized losses offset realized gains, $3,000 ordinary income offset, wash sale rule 30 days, indefinite carryforward, and short-term vs long-term character matters. Sophisticated participants understand harvesting central. Major institutional flows.
The framework emerged through tax evolution. Major US IRS Internal Revenue Code: capital gains taxed differently from ordinary income. Major Section 1091 (wash sale rule) prevents abuse. Major typical 30-day window before and after. Major capital gains rates: long-term 0%, 15%, 20% (held 1+ year). Major short-term ordinary rates. Major typical 22-37% federal. Major plus state. Major plus 3.8% NIIT high earners. Major Major modern robo-advisors automate: Wealthfront 2008 founded, started harvesting 2014. Major Betterment 2010. Major Schwab Intelligent Portfolios 2015. Major typical 0.25-0.40% management fees. Major Major historical: 2008 financial crisis huge harvesting year. Major 2022 S&P -19%, bonds -13% record year. Major typical sophisticated. Major Major crypto status: as of 2024, wash sale rule does NOT apply to crypto. Major loophole. Major Build Back Better proposed closing 2021. Major didn’t pass.
How Does Tax Loss Harvesting Work?
Knowing what Tax Loss Harvesting represents is the conceptual half; understanding mechanics determines proper analysis. Tax loss harvesting involves several specific elements. Mechanics: identify investments with losses. Major sell to realize loss. Major typical immediately. Major loss offsets gains dollar-for-dollar. Major long-term loss offsets long-term gain (and short-term). Major short-term loss offsets short-term gain first. Major typical net long-term capital loss can offset short-term gains. Major excess $3,000 annual against ordinary income. Major remainder carries forward indefinitely. Wash sale rule (IRC Section 1091): violation disallows. Major typical 30 days before AND after sale. Major substantially identical securities. Major typical can repurchase after 31 days. Major typical buy similar (S&P 500 ETF vs Total Market). Major SEC interprets. Major typical sophisticated participants. Tax character: long-term (1+ year held). Major short-term. Major typical sophisticated. Strategies: year-end harvesting December. Major typical sophisticated. Major continuous (robo-advisors). Major typical $50K+ portfolios benefit. Major typical sophisticated participants.
The variations across harvesting approaches reveal different mechanics. Year-end harvesting: traditional. Major December activity. Major typical “tax-loss selling” pressure. Major January Effect rebound. Major sophisticated participants. Continuous (robo-advisor): automated. Major Wealthfront 2014. Major Betterment. Major typical $50K+ accounts. Major typical sophisticated. ETF substitution: Vanguard Total Market (VTI) sold, S&P 500 (VOO) bought. Major typical substantially different. Major sophisticated participants. Major Major Direct indexing: holds individual stocks. Major typical 200-500 stocks. Major harvests individual losers. Major Wealthfront $50K+. Major Betterment Premium. Major typical sophisticated participants. Major Major Crypto harvesting: no wash sale rule. Major sell BTC at loss, buy back immediately. Major typical sophisticated. Major loophole may close. Major different mechanics. Major typical state taxes vary.
- Identify losses — losing positions.
- Realize loss — sell investment.
- Avoid wash sale — 30-day window.
- Substitute exposure — similar but different.
- Apply to gains — offset capital gains.
Worked example: Major tax loss harvesting examples demonstrate dynamics. Investor 2022 portfolio: $100K Apple, $100K Tesla, $100K NVIDIA. Major Tesla position $40K loss. Major sells Tesla at loss. Major immediately buys Lucid Motors (similar EV exposure but different security). Major realizes $40K loss. Major offsets $40K in other capital gains. Major saves $8K (20% LTCG rate). Major Major 2022 record year: S&P 500 -19% (worst since 2008). Major bonds -13% (worst ever). Major massive harvesting. Major typical robo-advisors automated. Major Wealthfront reported 25% more harvesting. Major Major direct indexing example: $1M portfolio holds 300 individual S&P stocks. Major typical harvests 30-50 losers annually. Major Major crypto example: investor bought BTC $69K (November 2021). Major sold $15K (November 2022) = $54K loss. Major immediately bought back at $15K (legal no wash sale). Major Major IRS rule: $3,000 ordinary income offset annually. Major married filing jointly. Major Major Roboadvisors: Wealthfront founded 2008 by Andy Rachleff. Major harvesting since 2014. Major Betterment 2010 Jon Stein. Major Major Major Build Back Better Act 2021: proposed closing crypto wash sale loophole. Major didn’t pass. Major crypto exempt as of 2024.
