"(B) Change of status.—In case of change of status of an employee as a result of which he would be entitled to a lesser amount of exemption, the employee shall, within ten days from such change, file with the employer a new withholding exemption certificate reflecting the change. If the change would entitle the employee to a greater amount of exemption, he may furnish the employer with a new withholding exemption certificate reflecting such change.

"(C) Use of certificates.—The certificates filed hereunder shall be used by the employer in the determination of the amount of taxes to be withheld.

"(D) Failure to furnish certificate.—Where an employee, in violation of this supplement, either fails or refuses to file a withholding exemption certificate, the employer shall withhold the taxes prescribed under schedule for zero exemption of the withholding tax table in sub article (a).

The return shall be filed and the payment made within twenty-five days from the close of each calendar quarter. The taxes deducted and withheld by employers shall be held in a special fund in trust for the Government until the same are paid to the said collecting officers.
