PS' functionality is not as robust as others. For instance, even though the states' returns are linked to the federals, like the income flowing through, they are not linked the opposite way.

IE, the MFJ vs. MFS comparison is federal only. The state cannot be brought into the federal comparison.

IE, the same is true for the planners. No state can come through to the federal planner.

You want more robust, try Lacerte or Ultratax. And you'll pay for it.
