Understand how wash sales affect RSU vesting with real 2025 Meta examples. Learn when losses are disallowed, how cost basis adjustments work, and what to watch for with monthly vests.
As someone who didn't sell the Q1 vest and are considering selling this time, this is the exact situation I am in. What a timely post! Super helpful as always
Given the lost added to the cost basis of the newly purchased shares, is it our own responsibility to keep track of this for filling tax return? Or generally the 1099B would adjust accordingly?

Exactly what I was looking for. Best substack ever!
About to join Meta and reading all this is exciting tbh
Thank you! A few questions:
- What if the Meta employee only sells stocks from the Q2 vest?
- What if Q1 shares are sold during some open window in the future when the stock is above water?
- is it different if the loss is long term? ie. the Q1 stocks under water are sold sometime in 2026?
This post is super helpful.

Your broker will track it. Often you will see a nice “w” symbol next to the lot.
It can get tricky if you do it across accounts or people in your household. In that case you would need to manually track.
