IBB tax-loss harvesting alternatives
iShares Biotechnology ETF (BlackRock) tracks NYSE Biotechnology. If you hold IBB at a loss, these ETFs track a different index, which generally makes them less likely to be considered “substantially identical” — while still moving closely with IBB during the 31-day wait.

30-day wash-sale calendar for IBB
The window is 30 calendar days before and after the sale (61 days total, IRC §1091(a)). Buying the replacement fund right away is the point of a swap; the dates above are about buying back the fund you sold, or anything substantially identical to it.
Before you swap
- Turn off dividend reinvestment for IBB in every account (including IRAs) for the window — a reinvested dividend is a purchase.
- Check automatic investments, a spouse’s accounts, and any IBB bought in the 30 days before the sale.
- Your broker generally only flags wash sales for the identical security in the same account. You are responsible for the rest.
- Read how wash sales work and the FAQ, then confirm your plan with a tax professional.
