Prior to the expiration of the time limitation following any year the Commissioner of Social Security may, if it is brought to the Commissioner’s attention that any entry of wages or self-employment income in the Commissioner’s records for such year is erroneous or that any item of wages or self-employment income for such year has been omitted from such records, correct such entry or include such omitted item in the Commissioner’s records, as the case may be. After the expiration of the time limitation following any year—
(A)#
the Commissioner’s records (with changes, if any, made pursuant to paragraph (5) of this subsection) of the amounts of wages paid to, and self-employment income derived by, an individual during any period in such year shall be conclusive for the purposes of this subchapter;
(B)#
the absence of an entry in the Commissioner’s records as to the wages alleged to have been paid by an employer to an individual during any period in such year shall be presumptive evidence for the purposes of this subchapter that no such alleged wages were paid to such individual in such period; and
(C)#
the absence of an entry in the Commissioner’s records as to the self-employment income alleged to have been derived by an individual in such year shall be conclusive for the purposes of this subchapter that no such alleged self-employment income was derived by such individual in such year unless it is shown that he filed a tax return of his self-employment income for such year before the expiration of the time limitation following such year, in which case the Commissioner of Social Security shall include in the Commissioner’s records the self-employment income of such individual for such year.
