TLT tax-loss harvesting alternatives
iShares 20+ Year Treasury Bond ETF (BlackRock) tracks US Treasury 20+ Year Index. If you hold TLT 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 TLT during the 31-day wait.

Sorted by 1-year correlation of daily total returns with TLT (through 2026-10-16). Holdings overlap = sum of the smaller weight of each common stock, from issuer holdings files; “n/a” where the issuer does not offer a free download or for bond/international/commodity funds.

Leveraged funds on the same index
Not suggested as swaps. They track US Treasury 20+ Year Index with daily leverage; some practitioners still consider them potentially substantially identical. (Inverse funds on the same index are omitted here.)

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