For investors

Harvest the loss without tripping the wash-sale rule.

When you sell at a loss to cut your tax, buying the same security back within thirty days is a wash sale, and the loss is denied. A similar, not identical, replacement keeps you invested and the loss intact.

Watch the quick version

See how it works through one simple example.

Is this you?

You are selling an investment at a loss to harvest it.
The thirty-day window applies before and after the sale.

Here is the idea, in plain words

Loss harvesting only helps if the loss counts. Buy the identical security back within thirty days and the IRS disallows it.

Instead, buy a similar but not substantially identical fund, keeping your four thousand dollar loss valid.

Your deduction holds up and you are never actually out of the market.

What this could be worth

Keep a harvested loss valid by replacing the holding with a similar, not identical, one.
  • 1Sell the losing position to realize the loss.
  • 2Buy a similar fund that is not substantially identical.
  • 3Wait at least 31 days before repurchasing the original.

What to watch out for

The honest version.

  • The thirty-day window runs in both directions around the sale.
  • It can apply across your accounts, including IRAs and a spouse's account.
  • Substantially identical is a judgment call. A different index or issuer usually helps.
