Okla. Admin. Code § 710:90-1-2
Oklahoma Statutes provide that any term used in the Oklahoma Income Tax Code shall have the same meaning as when used in a comparable context in the Internal Revenue Code, unless a different meaning is clearly required. The terms used in this Chapter are subject to control by the Oklahoma Statutes, and therefore subject to the interpretation and application provided by the Internal Revenue Code. [See: 68 O.S. Sections 2353, 2385.1] In addition, the following words or terms, when used in this Chapter, shall have the following meaning, unless the context clearly indicates otherwise:
"Employee", as described in this Section, means a "resident individual," performing services for an employer whether such services are performed within or without the State of Oklahoma, or both, and any "nonresident individual" performing services within the State of Oklahoma.
(A) The term "employee" includes every individual performing services if the relationship between him and the person for whom services are performed is the legal relationship of employer and employee, as follows:
(i) Generally, the relationship of employer and employee exists when the person for whom services are performed has the right to control and direct the individual who performs the services, not only as to the result to be accomplished by the work but also as to the details and means by which that result is accomplished.
(ii) An employee is subject to the will and control of the employer, not only as to what shall be done, but how it shall be done. It is not necessary that the employer actually direct or control the manner in which the services are performed; it is sufficient if the employer has the right to do so. In general, if the individual is subject to the control or direction of another merely as to the result to be accomplished by the work, and not as to the means and methods for accomplishing the result, he is not an employee.
(iii) The existence of an employer-employee relationship shall be determined, when in doubt, by an examination of the particular facts of each case.
(iv) If an employer-employee relationship exists, the designation or description of the relationship by the parties as anything other than that of employer and employee is immaterial.
(v) It is of no consequence that an employee is designated as a partner, coadventurer, agent, independent contractor, contract labor, or the like. It also does not matter how payments are made, what they are called or whether the service is performed full or part-time.
(B) Generally, persons who follow an independent trade, business, or profession, in which they offer their services to the public, such as physicians, attorneys, dentists, veterinarians, contractors and others, are not "employees. "
(C) Generally, an officer of a corporation is an employee of the corporation. However, an officer of a corporation who performs no services in this capacity or only minor services, and who neither receives nor is entitled to receive, directly or indirectly, any remuneration, is not considered to be an employee of the corporation.
(D) All classifications or grades of employees are included within the employer-employee relationship. Superintendents, managers and other supervisory personnel are employees. A director of a corporation in his capacity as such, is not an employee of the corporation. Officers of a Subchapter S Corporation are subject to these same provisions.
(E) An officer, employee or elected official of the United States, a state, a territory, the District of Columbia, or any agency, instrumentality, or political subdivision is considered an employee subject to Withholding Tax.
(F) Although an individual may be an employee, the services performed may be of such a nature or be performed under such circumstance that the remuneration paid does not constitute wages within the meaning of 68 O.S. Section 2385.1(e) or the Internal Revenue Code.
"Employer" means any person transacting business or deriving any income from sources within the State of Oklahoma for whom an individual performs or performed any services, of whatever nature, as the employee of such person. "Employer" does not include nonresident employers who have no place of business in Oklahoma and whose transactions are limited to the solicitation of orders for merchandise filled outside Oklahoma and shipped directly to a purchaser in Oklahoma.
(A) An "Employer" may be an individual, a corporation, a partnership, a trust, a joint-stock company, an association; or a syndicate, group, pool, joint venture, or other unincorporated organization, group or entity.
(B) The term "Employer" means not only individuals and organizations engaged in trade or business, but also organizations exempt from Income Tax, such as religious and charitable organizations, educational institutions, clubs, social organizations and societies.
(C) The term "Employer" includes the governments of the United States, the States, the Territories, the District of Columbia, their agencies, instrumentalities and political subdivisions.
(D) If the person for whom the services are or were performed does not have legal control of the payment of wages for such services, the term "Employer" means the person having such control.
(E) The term "Employer" includes an officer or employee of a partnership who is under a duty to act for a corporation or partnership to withhold and remit.
(F) The word "Employer" also means any person paying wages on behalf of a nonresident alien individual as defined by the Internal Revenue Code.
"Nonresident individual" means any individual other than a resident individual as defined by this Section. This includes "nonresident aliens" as defined by the Internal Revenue Code.
"Resident individual" means a natural person domiciled in Oklahoma who spends a total of more than seven (7) months of the taxable year within Oklahoma. Such person is presumed to be a resident in absence of proof to the contrary.
"Wages" means all remuneration (other than fees to public officials) for services performed by an employee for his employer unless specifically exempted.
(A) Generally, the medium in which remuneration is paid is immaterial. The term "wages" includes the cash value of all remuneration paid in any medium other than cash, such as stocks, bonds, or tangible property.
(B) The name by which remuneration is designated is also immaterial. Remuneration such as salaries, tips, fees, bonuses, commission on sales or on insurance premiums, pensions, and retired pay are considered wages if paid as compensation for services performed by the employee for his employer, unless specifically exempted as wages not subject to Withholding Tax by Oklahoma Statutes or the Internal Revenue Code.
(C) The basis upon which the remuneration is paid is immaterial. It may be paid on the basis of piecework, or as a percentage of profits, and may be paid hourly, daily, weekly, monthly, or annually.
(D) Remuneration for services performed constitutes wages subject to Income Tax Withholding, even though paid at a time after the employer-employee relationship no longer exists.
(E) Authorized fees to public officials such as notaries public, clerks of courts, sheriffs, etc., for services rendered in the performance of their official duties are not subject to Withholding Tax. However salaries paid such officials by the government or by a government agency or instrumentality are subject to withholding.
(F) The term "wages" does not include any remuneration for services performed by an employee for his employer which is specifically exempt from wages under 68 O.S. Section 2385.1(e) or the Internal Revenue Code. Any exception attaches to the remuneration for services performed by an employee and not to the employee as an individual. Remuneration for services performed which is specifically excepted from the definition of wages to which a voluntary withholding agreement is in effect are deemed to be wages for purposes of administering the provisions of the Oklahoma Income Tax Withholding Act.
(G) Oklahoma Statutes provide that any term used in the Oklahoma Income Tax Code shall have the same meaning as when used in a comparable context in the Internal Revenue Code, unless a different meaning is clearly required. The terms used in this Chapter are subject to control by the Oklahoma Statutes, and therefore subject to the interpretation and application provided by the Internal Revenue Code. Therefore, any remuneration paid for services performed by an employee for his employer not specifically exempted by Oklahoma Statute or specifically named in this Section as wages shall be subject to Oklahoma Income Tax Withholding if subject to Income Tax Withholding as required by the Internal Revenue Code.
