If you qualify, Head of Household is a much better income tax filing status than Single or Married Filing Separately. Why? Because you get a higher standard deduction ($2,750 higher for 2012) and may even qualify for credits not available to folks in the other two categories. Be careful, however – filing as Head of Household when you don’t meet the qualifications is fraud and you don’t want to go there!
