When NOT to Harvest Losses: Three Cases Where the Default Move Is Wrong

Skip the harvest in three situations: when you are in the 0% long-term capital gains bracket and expect to stay there, when you plan to donate the position to charity within the next year, and when the position is small enough that friction eats the benefit. Outside those cases, especially when you have realized gains to neutralize, the default of harvesting usually holds.

All three share one logic: a harvested loss saves money only if you were going to owe tax on the offsetting gain or income anyway.

The Three Situations Where Harvesting Is the Wrong Move

Case 1: You're in the 0% long-term capital gains bracket and expect to stay there.

In 2025, the 0% LTCG rate applies to taxable income up to roughly $48,350 for single filers and $96,700 for married filing jointly. Below those thresholds, a realized long-term gain costs you nothing in federal tax, so harvesting a loss to offset it produces zero benefit while resetting your basis lower, which means a larger taxable gain later when you're likely in a higher bracket. HENRYs (high earners, not rich yet) occasionally land here during a sabbatical, a gap between jobs, or the early years of a business.

Case 2: You plan to gift the position to a donor-advised fund (DAF) or qualified charity within the next year.

Contributing an appreciated security directly to a DAF or a 501(c)(3) does two things at once: you avoid capital gains tax on the embedded appreciation and you deduct the full fair market value. An underwater position gets no such treatment. The cleaner rule: evaluate any position you intend to donate in the next twelve months as a charitable gift first and a harvest candidate second. If it has a loss, sell it and give cash. If it has a gain, give the shares.

Case 3: The position is small and friction eats the benefit.

A $4,000 loss in the 24% bracket saves $960 in federal tax. That sounds worthwhile until you account for bid-ask spreads, the wash-sale clock, potential gains on the replacement, and state tax complexity where capital loss treatment doesn't conform to federal rules. For small or thinly traded positions the net benefit can slip below a few hundred dollars, and $300 is not worth introducing wash-sale risk into an otherwise clean portfolio. A rough threshold: if the tax savings don't exceed transaction costs plus one hour of actual review time, skip it. The broader point: a harvested loss that resets your basis at the wrong time or spoils a charitable opportunity isn't tax planning. It's tax activity.

Frequently Asked Questions

What if I'm in the 0% bracket now but expect a higher bracket next year?

Then the calculus shifts: if you'll owe tax on future gains, harvesting now to carry losses forward makes sense. The question is always when you'll actually use the loss.

Can I still harvest a loss if I plan to donate to a DAF more than a year out?

Yes. The twelve-month window is a rule of thumb, not a legal threshold, and the further out the donation, the more the harvest stands on its own merits.

Is wash-sale risk different in a DAF context?

Yes. A DAF is a separate legal entity, so buying a substantially identical security inside your DAF after harvesting it in a taxable account can trigger the wash-sale rule.

My robo-advisor harvests losses automatically. Should I turn that off?

Not necessarily, but understand what it's doing. Automation doesn't know about your planned charitable giving, your bracket in a transition year, or your small-position economics, so review its logic annually.

What to Do Next

What decides this for you. Your capital gains rate this year. In the 0% bracket a harvested loss offsets tax you were not going to pay, while permanently lowering your basis and creating a bill later.

Where it goes wrong. Harvesting has become reflexive, treated as free money whenever a position is down. It is not free. Every loss you take reduces basis, which raises the gain on a future sale, so the benefit is a deferral rather than a saving unless your rate later is lower than your rate now. Three situations reverse the logic entirely: a low-income year where gains would be taxed at nothing, a position you intend to give to charity where the appreciation would have escaped tax altogether, and a holding small enough that the spread and the effort exceed the benefit. Harvesting the third kind is busywork with paperwork attached.

Worth a conversation if this is an unusually low-income year, you make charitable gifts of appreciated securities, or you are near a bracket boundary. Deciding what not to harvest is as much of the work as deciding what to. Book a call.
