let's break this down a little bit
first, this is about your parents on their return, not you on YOUR return.
THEY can claim you as a dependent, even though you are married, if the reason YOU are filing is that you owe no taxes at all which would mean the only reason you are filing is to get back taxes that were withheld on YOUR W-2.
notice it say YOU (meaning your parents) can't claim a married person who files a joint return (meaning you).....
does that help?
