Why This Worksheet Exists
Tax-loss harvesting sounds simple until the wash-sale rule and the replacement trade start fighting each other.
This worksheet helps you write down the trade, the replacement, the expected tax use, and the parts of the plan most likely to blow up in execution.
Use this before you place the trade, not after. The point is to decide what you are replacing and what tax effect you are actually targeting.
If the worksheet shows a wash-sale problem, unclear holding periods, or no real gain-offset use, stop and clean that up first.

Frequently Asked Questions
Because the brokerage does not explain the replacement trade, the wash-sale exposure, or what tax purpose the harvest is actually serving.
People chase the loss, forget the replacement, and create a wash-sale or a portfolio move they did not really want.
Before harvesting any loss that matters. If the trade is meaningful enough to celebrate, it is meaningful enough to document.
