State tax filing

Yes and let's address each of your questions one at a time. Just to make sure though, I assume your daughter is under 18 or a full-time student under 24 and you are claiming her as a dependent on your return. This is the reason to file form 3800.

 

  1. The methodology for calculation of the standard deduction is correct based  on the percentage of CA income to total Income, 
  2. This does result in taxable income of $400, which results in a $4 tax liability.
  3. In answering your question, the $400 taxable income is derived from taking $900 and subtracting the $500 standard deduction. The standard deduction is already accounted for thus $400 is still taxable income.  You can't apply the standard deduction twice exclude taxable income.
  4. Do include form 3800 especially if your child falls under the provisions that I stated in my opening paragraph.
  5. I wish for continued success for you and your daughter in her education as well as successful pursuits in future endeavors.
