Not an expert... by any stretch... but I've been doing my own taxes including 2 small businesses for years. Since I started working.
SO... in a nutshell... if your itemizations are larger than the standard deduction, then itemize - however - they need to be SUBSTANTIALLY more than the standard to actually save you money.
As for dependents... they have to meet qualifications.
Me? I'm itemizing, but no dependents - married filing separate due to husband's business mess.
