2 U.S.C. § 1852: Withholding and remittance of State income tax

the law of any State provides for the collection of an income tax by imposing upon employers generally the duty of withholding sums from the compensation of employees and remitting such sums to the authorities of such State; and such duty to withhold is imposed generally with respect to the compensation of employees who are residents of such State; employed by the Office of the Architect of the Capitol, the United States Botanic Garden, or the Senate Restaurant; and who request the Architect to make such withholdings for remittance to that State. Any agreement entered into under subsection (a) of this section shall not require the Architect to remit such sums more often than once each calendar quarter. An individual employed by the Office of the Architect of the Capitol, the United States Botanic Garden, or the Senate Restaurant may request the Architect to withhold sums from his pay for remittance to the appropriate authorities of the State that he designates. Amounts of withholdings shall be made in accordance with those provisions of the law of that State which apply generally to withholding by employers. when the Architect first enters into an agreement with a State, a request for withholdings shall be effective on such date as the Architect may determine; and when an individual first receives an appointment, the request shall be effective on the day of appointment, if the individual makes the request at the time of appointment. An individual may change the State designated by him for the purposes of having withholdings made and request that the withholdings be remitted in accordance with such change, and he may also revoke his request for withholdings. Any change in the State designated or revocation is effective on the first day of the first pay period commencing on or after the day on which the request for change or the revocation is received in the appropriate office. The Architect is authorized to issue rules and regulations he considers appropriate in carrying out this subsection. The Architect may enter into agreements under subsection (a) of this section at such time or times as he considers appropriate. This section imposes no duty, burden, or requirement upon the United States, or any officer or employee of the United States, except as specifically provided in this section. Nothing in this section shall be deemed to consent to the application of any provision of law which has the effect of subjecting the United States, or any officer or employee of the United States to any penalty or liability by reason of the provisions of this section. For the purposes of this section, “State” means any of the States of the United States.
