It sounds as if he may qualify as a dependent on
your tax return as a qualifying relative if:
- He
was a member of your household the entire year.
- The
relationship between you and the dependent does not violate the law (you
can’t still be married to someone else. Also check your individual
state law. Some states do not allow you to claim a boyfriend or girlfriend
as a dependent even if your relationship doesn’t violate the law).
- You
meet all the other criteria for “qualifying relatives” (gross income and
support).
In order to determine if he meets the IRS
definition of a "qualifying relative" please see the following TurboTax FAQ:
