Tax-Loss Harvesting — How Robo-Advisors Save You Money

Overview

Tax-loss harvesting sells losing positions to offset capital gains, reducing your tax bill. Learn how robo-advisors automate this process and maximize after-tax returns. Leading robo-advisor platforms scan your portfolio daily for harvesting opportunities — far more frequently than manual approaches. For a deeper look at how the top platforms handle this, see our Wealthfront vs Betterment head-to-head. Be sure to review our tax guides to understand wash-sale rules and annual deduction limits before you start.

Key Takeaways

• Harvest a loss → immediately buy a similar (not identical) asset to maintain market exposure.
• The wash-sale rule: you can't rebuy the same or 'substantially identical' security within 30 days.
• Short-term losses offset short-term gains first (taxed at ordinary income rates) — the most valuable offset.
• Up to $3,000 in net losses can be deducted against ordinary income per year; the rest carries forward.

Practical Tips

• Wealthfront and Betterment offer daily tax-loss harvesting scanning — more opportunities than annual manual harvesting.
• Tax-loss harvesting is most valuable for high-income investors in the 32%+ tax bracket.
• Be aware of wash-sale violations across accounts — buying the same fund in your IRA within 30 days can disqualify the loss.
