Your W-2 must be available for import – most are ready by February 1, and some are disabled after the April filing deadline
We'll need the Box 1 amount from your W-2
You can also use the YTD (Year to Date) gross income from your year-end paystub. More info
In some cases, we'll need the Box d Control Number from your W-2, but only if your payroll provider requires this for the import (not all of them do).
NOTE: If you have an issue with importing due to having a blank Box d Control Number, you will just click skip import and then manually enter your W-2.
