IJR tax-loss harvesting alternatives

iShares Core S&P Small Cap ETF (BlackRock) tracks S&P Small Cap 600. If you hold IJR 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 IJR during the 31-day wait.

Avoid as a replacement: same index as IJR

These track the same index (S&P Small Cap 600). Buying one of them within the window is the classic “substantially identical” risk.
