Plot twist: They might actually be the same thing
Key Takeaways· When should I harvest gains instead of losses? During low-income years, you may qualify for the 0% capital gains rate, making it smart to intentionally realize gains. · What is “tax gain hoarding,” and why is it a problem? Over-harvesting losses can leave you with a very low cost basis, making it hard to diversify or rebalance without triggering big tax bills. · How does volatility affect tax harvesting? The 30-day wash-sale rule forces you to sit in cash or buy substitutes, both risky in volatile markets. Missing a quick rebound can cost more than the tax savings. |
Tax loss harvesting can be one of the most powerful tools in tax-efficient investing. When markets drop, realizing losses can offset gains, reduce your tax bill, and potentially save thousands.
But like any powerful tool, it needs to be used strategically. In high-income years, aggressive loss harvesting can save thousands. In low-income windows, strategic gain harvesting can save even more. And sometimes, the best move is doing nothing at all.
The complexity isn’t in understanding these strategies individually. It’s in coordinating them with your income trajectory, liquidity needs, concentration risk, and estate goals, and being willing to adjust as circumstances change.

When Tax Loss Harvesting Makes Perfect Sense
If you’re in your peak earning years, realizing losses is often the right move. A $10,000 short-term capital loss could save you $3,700 in federal taxes (at the 37% bracket) plus state taxes and Net Investment Income Tax. Over a career, these savings compound significantly.
Loss harvesting also works beautifully for long-term wealth you won’t touch for decades. You defer taxes now, let the money compound, and your heirs may receive a step-up in basis that eliminates the gains entirely.
The strategy becomes problematic only when it’s applied reflexively—regardless of your income level, timeline, or portfolio composition. That’s when ‘good tax planning’ can accidentally create bigger problems.
The Myth: “Capital Gains Are Always Bad”
We recently met with a couple in their mid-50s whose income dropped sharply when the husband left a corporate job to start a consulting business. When we asked what tax strategy they used during that first low-income year, he said, “Nothing. We just enjoyed not paying taxes.”
But once we reviewed their portfolio, we found over $1 million in embedded gains across a few concentrated stocks. During those low-income years, they could have realized $100,000–$150,000 in gains at a federal tax rate of 0%, an opportunity their previous advisor missed entirely.
Most people assume capital gains are always taxed at 15%, but today’s tax code includes a 0% bracket for many taxpayers in lower-income years. In other words, they had a free chance to reset their cost basis, and no one told them.
When we showed this couple what they’d missed, they were (rightfully) furious. Those tax-free gains are now gains they’ll have to realize later, likely owing tens of thousands in unnecessary taxes.

The 0% Strategy: In years when your income is unusually low, you can intentionally realize capital gains and pay zero federal tax. It’s a rare window to clean up your portfolio for free.
And career transitions aren’t the only time this strategy shows up. We regularly see 0% capital gains opportunities in situations like:
- Business owners with major write-offs: Large equipment purchases or other capital investments can create big deductions. In some years, clients’ taxable income drops so low that they can realize significant capital gains at a 0% federal rate.
- Early retirees before Social Security: Those “in-between” years after leaving a primary career but before turning on retirement income are often ideal for strategic gain harvesting.
Ultimately, the sophistication isn’t in avoiding gains; it’s in timing them. Our goal is for you to pay 0% when possible, 15% when necessary, and avoid the 20%+ bracket whenever we can.
What Happens When You’re Too Good at Harvesting Losses?
A few months ago, we reviewed a $1 million portfolio for a prospective client whose previous advisor had been overly aggressive with tax loss harvesting, selling every possible loser to offset gains.
The result was a cost basis under $400,000 and more than $600,000 in embedded gains.
They wanted to rebalance, diversify, fund 529s, and pay down their mortgage, but psychologically, they were stuck. It can feel impossible to realize a $600,000+ gain, even though the gain exists whether they sell or not.
This is tax gain hoarding: letting so much appreciation build up that your wealth becomes functionally “trapped.” Beyond the psychological hurdle, tax gain hoarding creates some very real (and very expensive) problems:
Concentration Risk
We see this all the time with employee stock purchase plans. You buy shares at a 15% discount, hold them for a year to avoid short-term gains… then the stock jumps 40%, and you don’t want to sell. More shares vest, those have gains too, and before you know it, a huge chunk of your wealth is tied to one company, all because you’re avoiding taxes.
That original discount was found money. Our motto: Don’t let the tax tail wag the investment dog. Tax decisions shouldn’t override the bigger-picture strategy we’ve built with you.
Portfolio Drift
If we’ve designed a 50/50 mix of stocks and bonds, and stocks experience a strong rally, the allocation can shift to 60/40 or even 70/30 over time.
When that happens, we evaluate whether rebalancing is appropriate, considering both the investment implications and the tax impact, so that your portfolio doesn’t quietly take on more risk than intended.
Tax Loss Harvesting: If it Feels as Simple as Mowing a Lawn, You’re Doing it Wrong
The complexity of tax loss harvesting becomes especially clear in volatile markets. When you harvest a tax loss, the wash sale rule requires you to avoid buying the same (or “substantially identical”) investment for 30 days, leaving you with two imperfect choices:
Imperfect Option 1: Sit in Cash
You sell the position and wait out the 30 days. But if the market rebounds—say 8% on $100,000—you’ve just missed an $8,000 gain. In many cases, that loss outweighs the tax benefit.
Imperfect Option 2: Buy a Substitute Investment
Instead of sitting in cash, you swap into something similar by selling the S&P 500 fund and buying a large-cap fund.
After 30 days, do you sell the substitute? If it’s up, you may trigger short-term gains, taxed at much higher ordinary income rates. If you hold it for a year to get long-term treatment, you might still end up with gains you never intended to create.
This is where a sophisticated approach matters most. In down markets, there are more loss-harvesting opportunities, but the stakes of getting the execution wrong are also higher.
The key isn’t just knowing that you can harvest losses. It’s knowing when it’s actually worth doing.
A Smarter Approach to Tax Harvesting
The smarter alternative to reflexive loss harvesting or gain hoarding starts with your specific goals and timeline.
If you’ll need money from an account soon, we avoid strategies that could trap you with unnecessary embedded gains. For long-term or legacy assets, we tailor the opposite approach (harvesting losses and holding gains) because your heirs may receive a step-up in basis that eliminates those taxes entirely.
We also proactively watch for low-income windows where you can potentially realize gains at 0% or reduced rates.
All of this works because we’re looking at the full picture of your tax bracket, cash flow, allocation, estate goals, concentration risk, and income sources.
