If the Commissioner of Social Security determines, on the basis of information obtained by or submitted to the Commissioner, that it may reasonably be expected that an individual entitled to benefits under section 402 of this title for any taxable year will suffer deductions imposed under subsection (b) by reason of his earnings for such year, the Commissioner of Social Security may, before the close of such taxable year, suspend the total or less than the total payment for each month in such year (or for only such months as the Commissioner of Social Security may specify) of the benefits payable on the basis of such individual’s wages and self-employment income; and such suspension shall remain in effect with respect to the benefits for any month until the Commissioner of Social Security has determined whether or not any deduction is imposed for such month under subsection (b). The Commissioner of Social Security is authorized, before the close of the taxable year of an individual entitled to benefits during such year, to request of such individual that he make, at such time or times as the Commissioner of Social Security may specify, a declaration of his estimated earnings for the taxable year and that he furnish to the Commissioner of Social Security such other information with respect to such earnings as the Commissioner of Social Security may specify. A failure by such individual to comply with any such request shall in itself constitute justification for a determination under this paragraph that it may reasonably be expected that the individual will suffer deductions imposed under subsection (b) by reason of his earnings for such year. If, after the close of a taxable year of an individual entitled to benefits under section 402 of this title for such year, the Commissioner of Social Security requests such individual to furnish a report of his earnings (as computed pursuant to paragraph (5) of subsection (f)) for such taxable year or any other information with respect to such earnings which the Commissioner of Social Security may specify, and the individual fails to comply with such request, such failure shall in itself constitute justification for a determination that such individual’s benefits are subject to deductions under subsection (b) for each month in such taxable year (or only for such months thereof as the Commissioner of Social Security may specify) by reason of his earnings for such year.
