Food stamps are not an issue.
You
can claim a boyfriend or girlfriend and their children as dependents if they
are your qualifying relatives.
Boyfriend/Girlfriend: To be a qualifying relative (dependent) you
don't have to be an actual relative - however,
- whoever
claims them must provide more than 1/2 of the individuals support,
- they must
not earn more than $4,000 in 2015 in
(social security doesn't count),
- they must
not file a joint return with another
- If not an
actual relative, they must live with the person claiming them all 365 days
of the year
- they must
be a US citizen or resident of the US, Canada or Mexico
- they are
not a qualifying child of another taxpayer.
If your girlfriend's child is also your child and lived with you (or you and her) for more than 1/2 of the year (or since birth), then the child could be claimed as a dependent by you.
