I know +1 votes count towards your score for associated tags, but I wanted to know if that is true for accepted answers too.
If so, I assume its considered 1 point? Also, if the asker +1 votes the answer and accepts it, does it give you +2 to the tag?
No, it does not.
What is this tag score you speak of?
A tag score is basically the combined total of all the upvotes (+1) and downvotes (-1) you've accumulated on answers under that specific tag (votes on questions do not count). Acceptance of an answer doesn't have any weight in the score. As well, posts which are in community wiki status or that have been deleted do not count towards your tag score. Tag scores are only recalculated once daily, at 03:00 UTC.
