Ok, so I'd like to know in the other direction - if you've (accidently) underestimated and they've already paid you the school kids bonus, and then it turns out you weren't eligible for FTB part A - do they require you to pay back the school kids payment part of it?

Likewise, if it turns out you've just been nudged out of the FTB bracket by an eensy weensy bit, what happens about Medicare extended safety net payments (that they have already paid) for that period. Do the medicare people come after you with a big stick? Or do they get their pound of flesh in subsequent years (until it's all "paid back").

PS - Also, is it just me or have the FTB eligibility incomes shrunk a bit over the last couple of years?
