Collection of, and liability for, employee tax; in general

(a) The employer shall collect from each of his employees the employee tax with respect to wages for employment performed for the employer by the employee. The employer shall make the collection by deducting or causing to be deducted the amount of the employee tax from such wages as and when paid. (For provisions relating to the time of such payment, see § 31.3121(a)-2.) The employer is required to collect the tax, notwithstanding the wages are paid in something other than money, and to pay over the tax in moey. (As to the exclusion from wages of remuneration paid in any medium other than cash for certain types of services, see § 31.3121(a)(7)-1, relating to such remuneration paid for service not in the course of the employer's trade or business or for domestic service in a private home of the employer; and § 31.3121(a)(8)-1, relating to such remuneration paid for agricultural labor.) For provisions relating to the collection of, and liability for, employee tax in respect of tips, see § 31.3102-3. For special rules relating to Additional Medicare Tax imposed under section 3101(b)(2), see § 31.3102-4.

(b) The employer is permitted, but not required, to deduct amounts equivalent to employee tax from payments to an employee of cash remuneration to which the sections referred to in this paragraph (b) are applicable prior to the time that the sum of such payments equals—

(1) $100 in the calendar year, for service not in the course of the employer's trade or business, to which § 31.3121(a)(7)-1 is applicable;

(2) The applicable dollar threshold (as defined in section 3121(x)) in the calendar year, for domestic service in a private home of the employer, to which § 31.3121(a)(7)-1 is applicable;

(3) $150 in the calendar year, for agricultural labor, to which § 31.3121(a)(8)-1(c)(1)(i) is applicable; or

(4) $100 in the calendar year, for service performed as a home worker, to which § 31.3121(a)(10)-1 is applicable.

(c) At such time as the sum of the cash payments in the calendar year for a type of service referred to in paragraph (b)(1), (b)(2), (b)(3) or (b)(4) of this section equals or exceeds the amount specified, the employer is required to collect from the employee any amount of employee tax not previously deducted. If an employer pays cash remuneration to an employee for two or more of the types of service referred to in paragraph (b)(1), (b)(2), (b)(3) or (b)(4) of this section, the provisions of paragraph (b) of this section and this paragraph (c) are to be applied separately to the amount of remuneration attributable to each type of service. For provisions relating to the repayment to an employee, or other disposition, of amounts deducted from an employee's remuneration in excess of the correct amount of employee tax, see § 31.6413(a)-1.
