(a)
(1) As used in this chapter, unless the context clearly requires otherwise, “employing unit” means any individual, organization, or legal representative of a deceased person.
(2) This term includes but is not limited to any partnership, association, trust, estate, joint-stock company, insurance company, or corporation, whether domestic or foreign, and the receiver, trustee in bankruptcy, trustee, or successor of any of the foregoing which has had one (1) or more individuals performing services for it within this state.
(3) “Employing unit” shall also mean the state or any agency, board, commission, department, institution, or instrumentality of the state and any political subdivision of the state and any instrumentality of any political subdivision of the state, any instrumentality of more than one (1) of the foregoing, any instrumentality of the foregoing and one (1) or more other states or political subdivisions, which has had one (1) or more individuals performing services for it.
(b)
(1) All individuals performing services within this state for any employing unit which maintains two (2) or more separate establishments within this state shall be deemed to be performing services for a single employing unit for all the purposes of this chapter.
(2) Each individual employed to perform or to assist in performing the work of any person in the service of an employing unit shall be deemed to be engaged by the employing unit for all the purposes of this chapter, whether the individual was hired or paid directly by the employing unit or the person, provided that the employing unit had actual or constructive knowledge of the work.
(c)
(1) Any employer may on or before December 1 prior to the year the application is to become effective make application in writing to the Division of Workforce Services to participate in a joint account with one (1) or more other employers.
(2) The division shall approve those applications that meet the requirements of this section.
(3) Any application to participate in a joint account may be filed on or before December 1 prior to the year the membership is to become effective, provided, however, all contributions, interest, and penalties due from the applicant-employer must be paid prior to the effective date of the employer's membership in the joint account.
(4) All such applications shall be accepted only on the condition that the applicant waive all rights he or she has in his or her individual employer account under the law when the division approves his or her application and merges his or her individual account into a joint account for experience-rating purposes.
(5) Each applicant-employer shall agree to assume joint and several liability for any contributions, interest, and penalties accruing on the part of any one (1) of the employers participating in the joint account during the duration of the account in consideration for the division's granting the applicant-employer the right to participate in it.
(6) Each employer participating in a joint account agrees to maintain a sufficient record of the employee's own employment in order that the employer can furnish the division with information necessary to enable the division to make proper certification to the Internal Revenue Service under the Federal Unemployment Tax Act and to enable the division to determine any benefit charges against the employee's separate account.
(7) No reduced rate of contributions shall be established for any joint account until each participating employer is individually eligible for the calculation of a contribution rate.
(8) All joint accounts will be maintained only on a calendar-year basis, and joint accounts must be maintained for a minimum period of two (2) calendar years unless terminated sooner by action of the division.
(9) All contribution credits for all employers in a joint account will be calculated together. All benefit payments chargeable against all employers in a joint account will be calculated together. The average annual payroll of the joint account will be the average of the annual payrolls of all employers participating in the account.
(10) If any individual, type of organization, or employing unit succeeds to the business of an employer participating in a joint account under conditions which would require the transfer of any separate account of that employer to the successor, the successor shall be ipso facto a member of the joint account.
(11)
(A) Withdrawal from a joint account by any participating employer may be approved if the request for withdrawal is made in writing to the division on or before September 30 of the year prior to the year for which the withdrawal is to be effective.
(B) The withdrawing employer shall as of the effective date of withdrawal be treated in all respects as a newly liable employer regardless of all prior contributions or benefit payment experience.
(C) The remaining employer or employers shall continue to constitute the joint account. The withdrawal or termination of all except one (1) member shall not dissolve such joint account unless and until such last member shall withdraw or terminate.
(12) Participation in a joint account shall not affect the right of any employer to terminate the employer's liability, but after termination, the employer shall in all respects be treated as a withdrawing employer under this section.
