§404.321. When a period of disability begins and ends. — Inbound Citations

(i) If you worked during the reentitlement period and we decided that your disability ceased during the reentitlement period because of your work under paragraph (a)(1) of this section, we will find that your entitlement to disability benefits terminates in the first month in which you engaged in substantial gainful activity after the end of the reentitlement period (see § 404.325). (See § 404.321 for when entitlement to a period of disability ends.) When we make this determination, we will consider only your work in, or earnings for, that month; we will not apply the provisions of §§ 404.1574(c) and 404.1575(d) regarding unsuccessful work attempts, the provisions of § 404.1574a regarding averaging of earnings, or the special rules in §§ 404.1574(b)(3)(iii) and 404.1575(e) for evaluating the work you do after you have received disability benefits for at least 24 months.
