It depends on what type of government forms you are referring to. For your income taxes, if he does not qualify as a dependent you cannot claim him. However if, for instance, you are attempting to get a tax payment arrangement you may need to count his income/expenses in your household calculation in many instances. You need to be much more specific.

It's not clear what "government forms" you are filling out. Whether you may claim your father as a "dependent" on your federal income tax return and whether you must report him as part of your household on other (non-tax related) government forms, may be different.
However, if you are wondering whether you may claim your father as a dependent on your federal income tax return, the answer is "probably not."
You may claim your father as a dependent on your 2012 federal income tax return only if his gross income for 2012 is less than $3,800 AND you provided over one-half of your father's (financial) support during 2012.
