With reporting for SSDI, they go back the whole year, you have to send in a year's worth of income, and where it gets hard is there might be 3 paychecks in one month, instead of two, and you might go over your allowance. If they ever think they paid you too much, you have to pay it back. They take $50 out of future checks, until it's paid off. Schizophrenics know this.
