What about securities transferred via ACAT?

Any stock or options position that transferred to your tastyworks account via ACAT (Automated Customer Account Transfer) has been reported to our clearing firm, Apex Clearing Corporation. The trade price listed for any transferred security on the tastyworks platform may not be your cost basis since the trade price marked is on the day the transfer came in.


What can affect my cost basis?

The short answer: a lot of things. The following list includes but is not limited to:

  1. Dividend Reinvestment
  2. Adding to a position (stock or options)
  3. Splits
  4. Spinoffs
  5. Mergers

Any adjustments to your cost basis may also appear in your 1099-B.
