31.3401(a)(11)-1—Remuneration other than in cash for service not in the course of employer's trade or business.

Remuneration paid for active service as a member of the Armed Forces of the United States performed in a month during any part of which such member served in a combat zone (as determined under section 112) or is hospitalized at any place as a result of wounds, disease, or injury incurred while serving in such a combat zone is excepted from wages and is, therefore, not subject to withholding. The exception with respect to hospitalization is applicable, however, only if during all of such month there are combatant activities in some combat zone (as determined under section 112 ). See § 1.112-1 of this chapter (Income Tax Regulations).
(a) Remuneration paid in any medium other than cash for services not in the course of the employer's trade or business is excepted from wages and hence is not subject to withholding. Cash remuneration includes checks and other monetary media of exchange. Remuneration paid in any medium other than cash, such as lodging, food, or other goods or commodities, for services not in the course of the employer's trade or business does not constitute wages. Remuneration paid in any medium other than cash for other types of services does not come within this exception from wages. For provisions relating to cash remuneration for service not in the course of employer's trade or business, see § 31.3401(a)(4)-1.
(b) As used in this section, the term “services not in the course of the employer's trade or business” has the same meaning as when used in § 31.3401(a)(4)-1.
