In this article, we’ll explore how investors can use tax loss harvesting to shape their legacy, why automation matters for long-term compounding, and how today’s volatility creates once-in-a-decade opportunities to optimize for both life and death.

The Big Picture: Step-Up in Basis vs. Realizing Losses

If they sell $200K of Eli Lilly stock to fund a home renovation, they’d realize ~$150K in capital gains and owe about $30K in federal taxes.

But if they

Those harvested losses didn’t need to be used right away either. If realized in 2023 and not needed until 2025, they would carry forward.

For Janice and Robert, this is a way to

Why Automation Makes All the Difference

Most DIY investors miss tax loss harvesting opportunities. Why?

Because markets move fast, and identifying loss lots in a diverse portfolio requires constant monitoring. You need to:

• Track short- and long-term loss lots
• Avoid wash sales by repurchasing “similar but not identical” securities
• Maintain exposure during the 30-day no-buy window
• Strategically harvest losses

An automated AI tool takes care of all of that. It scans every account daily, looking for harvestable losses, applies tax rules in real time, and reinvests proceeds intelligently—ensuring exposure is preserved.

For estate-focused investors, this means:

Key Takeaways for Estate-Focused Investors

1. Harvested losses aren’t wasted

• They can reduce your taxes during life, fund large purchases, and compound tax-free.

2. Automation ensures you don’t miss opportunities

3. Long-term planning benefits most from harvesting.

• Those who consistently harvest small losses over decades save the most.

4. Estate and legacy planning is about flexibility.

• Tax loss harvesting gives you optionality to sell or gift strategically, without letting the tax tail wag the investment dog.

Final Thoughts: Tax Optimization is a Legacy Tool

Many investors think about estate planning through the lens of wills, trusts, and account titling. But

If you’re harvesting losses consistently, you’re giving your future self—and your heirs—a better starting point. Fewer taxes mean more capital to reinvest, gift, or pass on.

And thanks to modern AI tools, these strategies are no longer reserved for family offices or elite advisors. They’re available to anyone who’s willing to invest wisely, think long term, and let software do the heavy lifting.

Tax loss harvesting is no longer just an end-of-year hack. Done right, it’s a
