🎓 Advanced Harvesting Strategies

The 0% Capital Gains Bracket

For 2024, single filers with income under $47,025 and married couples under $94,050 pay 0% on long-term capital gains. Harvest gains to "reset" cost basis tax-free.

Tax-Loss Harvesting

Realize losses to offset gains or up to $3,000 of ordinary income. Repurchase similar (not identical) assets after 30 days to avoid wash sale rules.

Asset Location Strategy

Keep tax-inefficient assets in retirement accounts, harvest gains on tax-efficient assets in taxable accounts when in low brackets.

❓ Frequently Asked Questions

Q1: When should I harvest capital gains?

Harvest gains when income falls in the 0% or 15% capital gains brackets — typically early retirement years before Social Security starts or during low-income years. This resets cost basis at low or no tax cost.

Q2: What's the wash sale rule?

A tax loss cannot be claimed if the same or a "substantially identical" security is repurchased within 30 days before or after the sale. Buy a similar but different investment to avoid this.

Q3: Should I harvest losses in a down market?

Yes! Tax-loss harvesting is most valuable during market downturns. Realize losses to offset current or future gains, or deduct up to $3,000 against ordinary income annually.

Q4: Can I harvest gains in my 401k or IRA?

No. Harvesting only applies to taxable accounts. Retirement accounts grow tax-deferred regardless, so there's no benefit to realizing gains inside them.

Q5: What if I'm already in a high tax bracket?

Focus on tax-loss harvesting instead. Save gains harvesting for retirement years when income is likely in lower brackets and can take advantage of 0% or 15% rates.
