(a) First penalty period. The first penalty period begins on the first day of the month you apply for SSI benefits and ends on the day we first learn that you should have made a required report, but did not do so within 10 days after the close of the month in which the event happened. There may be more than one required report overdue at the end of the first penalty period, but we will impose no more than one penalty deduction for the period.

(b) Extension of first penalty period. If you have good cause for not making a report on time (see § 416.732), we will extend the first penalty period to the day when we learn that you should have made another required report, but did not do so within 10 days after the close of the month in which the event happened. There may be more than one required report overdue at the end of the extended first penalty period, but we will impose no more than one penalty deduction for the extended period.
