I would like to confirm if I'm doing this correct.

We add the our W2s only to the person whom it belongs to.  THEN we do the manual community property split on this income where one of us adjusts down and the other adjusts up to the even split amount on each return.

For rental property income we both enter full income+expenses but just specify we have 50% ownership on each return.

For bank account interest and last year's taxable state tax return we are simply manually splitting these incomes when entering it on each return.

For a HSA account thats only in my name I am NOT splitting this and reporting all of the contributions+distributions on my return only.
