This is an old post but I can see that no one has answered this, at least not properly. A couple of posts make the question seem foolish, which it isn't. As far as I can tell, there is no rule to has or have, which is what you should be asking about. Anything that applies to have or has will, of course, apply to haven't or hasn't. It seems that has/hasn't is used with the third person pronouns: s

Hasn't is singular

Haven't is plural

He hasn't gone to the store.

They haven't gone to the store.

Has not = Hasn't

Have not = Haven't

Hi guys,
Let;'s all be clear about the Simple Present tense of the verb 'have'.

Singular
I have
you have
he/she/it has

i haven't gone to the store. is that not singular?

Anonymousi haven't gone to the store. is that not singular?

You need to look at person as well as singular/plural.

Singular:
Fist person: I have
Second person: You have
Third-person: He has

Only third-person singular takes "has."
