What is Tax-Loss Harvesting?
Tax-loss harvesting (TLH) turns temporary market dips inside a taxable brokerage account into permanent IRS tax savings without taking you out of the market.
How Automated TLH Works (Wealthfront / Betterment)
- Suppose your S&P 500 ETF (
VOO) drops $8,000 below your purchase price during a market correction. - The algorithm sells
VOOto lock in an $8,000 realized capital loss and simultaneously buys a highly correlated—but not "substantially identical"—ETF (such asSCHBorITOT) in the same second. - Your portfolio stays 100% invested in U.S. equities, while the $8,000 loss offsets 100% of any realized capital gains PLUS up to $3,000 of ordinary W-2/1099 income on Schedule D, with unused losses carrying forward indefinitely.
