Is tax-loss harvesting actually worth doing?

Tax-loss harvesting sounds more sophisticated than it is.

If an investment is down, you may be able to sell it, realize the loss, and use that loss to offset capital gains. If losses exceed gains, a limited amount can offset ordinary income, with the rest carried forward.

That can be useful. But the strategy is often oversold.

Where it helps

Tax-loss harvesting can help when you have capital gains from selling investments, real estate, a business asset, or concentrated stock.

It can also create room to rebalance a portfolio that has drifted without creating as much tax cost.

Where people get sloppy

The danger is letting the tax tail wag the investment dog. A loss is not valuable simply because it exists. It should be harvested only if the replacement investment keeps the portfolio aligned and avoids wash-sale problems.

You do not want to save a little tax and accidentally change the risk of the portfolio in a way that hurts the plan.

The planning version

The better version is coordinated. If a business owner is selling an asset, an executive has concentrated stock, or a retiree is managing gains while doing Roth conversions, harvesting losses can be one piece of a larger tax strategy.

By itself, it is a tactic. Connected to the plan, it can be useful.
