An application under this subsection shall not constitute a claim for credit or refund.

(b) Allowance of adjustment
(1) Limited examination of application
Within a period of 45 days from the date on which an application for an adjustment is filed under subsection (a), the Secretary shall make, to the extent he deems practicable in such period, a limited examination of the application to discover omissions and errors therein, and shall determine the amount of the adjustment upon the basis of the application and the examination; except that the Secretary may disallow, without further action, any application which he finds contains material omissions or errors which he deems cannot be corrected within such 45 days.
(2) Adjustment credited or refunded
The Secretary, within the 45-day period referred to in paragraph (1), may credit the amount of the adjustment against any liability in respect of an internal revenue tax on the part of the corporation and shall refund the remainder to the corporation.
(3) Limitation
No application under this section shall be allowed unless the amount of the adjustment equals or exceeds (A) 10 percent of the amount estimated by the corporation on its application as its income tax liability for the taxable year, and (B) $500.
(4) Effect of adjustment
For purposes of this title (other than section 6655), any adjustment under this section shall be treated as a reduction, in the estimated income tax paid, made on the day the credit is allowed or the refund is paid.
