Tax-Loss Harvesting

Also known as Loss harvesting

Tax-loss harvesting realizes investment losses to offset gains or other taxable amounts where applicable while maintaining an intended portfolio exposure.

Why tax-loss harvesting matters

It may improve after-tax return, but benefits depend on jurisdiction, investor, future gains, rates, timing, and transaction costs.

How it is applied

Investors identify eligible losses, lots, offset rules, replacement exposure, wash-sale or equivalent restrictions, costs, and tracking impact.

Portfolio example

An investor sells one index fund at a loss and buys a sufficiently different replacement, subject to local rules.

How to interpret it

The benefit is often tax deferral rather than permanent savings. Investment merit should not be sacrificed solely for tax.

Limitations and common misconceptions

Rules vary and related accounts or derivatives can trigger restrictions. Spreads, market movement, and future tax rates can erase benefit.
