What Is Tax-Loss Harvesting
- A strategy to sell investments at a loss to offset taxable gains in the same year
- Reduces current year tax liability while maintaining overall portfolio allocation
- Available to all investors in taxable accounts, not applicable to retirement accounts
- Must follow strict IRS wash sale rules to preserve the tax benefit
How Tax-Loss Harvesting Works
- Sell losing investments to realize capital losses before December 31st
- Use losses to offset capital gains dollar-for-dollar in the same tax year
- Excess losses offset up to $3,000 of ordinary income annually
- Remaining losses carry forward indefinitely to future tax years
- Reinvest proceeds in similar but not identical securities to stay invested
Wash Sale Rules
- Cannot repurchase the same or substantially identical security within 30 days
- The 30-day window includes 30 days before and 30 days after the sale date
- Violations disallow the tax loss and add the disallowed amount to the new cost basis
- The rule applies across spouse's accounts and retirement accounts you control
Substantially Identical Securities
- Same company stock or bonds from the same issuer are always considered identical
- Different share classes of the same company are typically considered identical
- ETFs tracking the same index are usually identical; different indexes generally are not
- Sector ETFs and broad market funds are generally not considered identical
Short-Term vs Long-Term Losses
- Short-term losses (held one year or less) offset short-term gains first
- Long-term losses (held over one year) offset long-term gains first
- Excess losses then offset the opposite type of gains after same-type matching
- Long-term capital gains receive preferential tax rates (0%, 15%, or 20%)
Implementation Best Practices
- Review your portfolio for harvesting opportunities quarterly, especially before year-end
- Maintain asset allocation by purchasing similar but different replacement securities
- Track cost basis carefully and use the specific identification method
- Harvest losses in taxable accounts while keeping winners in retirement accounts
Key Takeaways
- Harvest losses before December 31st to reduce current year taxes
- Avoid wash sale violations by waiting 31 days before repurchasing
- Offset gains first, then up to $3,000 of ordinary income annually
- Maintain portfolio allocation with similar but different replacement securities
