BIL tax-loss harvesting alternatives
State Street SPDR Bloomberg 1-3 Month T-Bill ETF (State Street) tracks Bloomberg US Treasury - Bills (1-3 M). If you hold BIL 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 BIL during the 31-day wait.

30-day wash-sale calendar for BIL
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 BIL in every account (including IRAs) for the window — a reinvested dividend is a purchase.
- Check automatic investments, a spouse’s accounts, and any BIL 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.
