Tax-Loss Harvesting
Quick Definition
Selling investments at a loss to offset capital gains taxes, then reinvesting in similar (but not identical) assets.
What Is Tax-Loss Harvesting?
Tax-loss harvesting is a strategy of selling investments that have declined in value to realize losses that offset capital gains, reducing your tax bill while maintaining your investment strategy.
How It Works:
- Identify investments trading below your cost basis
- Sell to realize the loss
- Use loss to offset gains (and up to $3,000 ordinary income)
- Reinvest in similar (not identical) investment
- Carry forward unused losses to future years
Example:
- You have $10,000 in gains from Stock A
- Stock B has a $10,000 loss
- Sell Stock B → $0 net taxable gains
- Buy similar ETF to maintain market exposure
- Tax savings: $1,500-$3,500+ depending on tax bracket
Wash Sale Rule: You CANNOT buy "substantially identical" securities within 30 days before or after the sale:
- ❌ Sell AAPL, buy AAPL within 30 days
- ✅ Sell AAPL, buy technology ETF
- ✅ Sell S&P 500 fund, buy total market fund
- ❌ Sell VTI, buy VTSAX (substantially identical)
Benefits:
- Reduce current year taxes
- Maintain market exposure
- Compound tax savings over time
- No limit on losses to harvest
Best Practices:
- Review portfolio quarterly
- Consider transaction costs
- Document all trades
- Use tax-advantaged accounts for frequent trading
- Robo-advisors often automate this
