Deductions & credits

Need some clarification here before I can provide guidance.
You indicate "we" - can you provide more detail here; is this 2 individuals, 4 individuals, etc"
Is the "we" husband and wife?  If yes, are you in a community property state?
Is it a safe assumption that the single member LLC's are owned by individuals?
