that is it

Nothing more needed

That is it signals completion or finality—the end has been reached, nothing more follows.

It confirms something is correct or sufficient: That is it, you've got it.

It also expresses exasperation or a breaking point: That is it, I'm done arguing.

Often contracted to that's it.
