Morgan Stanley at Work seems to track wash sales. Last year I had two vests in May, one week apart. I'd instructed the brokerage to sell some of those shares on vest. On the first date, I experienced a capital loss (less than $20), due to price movement between the RSU vesting and the broker selling the resulting stock. This was reported on the 1099B as a disallowed wash sale due to my acquisition of more stock with the second vest a week later.
