§ 72-1351 — EXPERIENCE RATING AND VOLUNTARY TRANSFERS OF EXPERIENCE RATING ACCOUNTS

(1) Subject to the other provisions of this chapter, each eligible and deficit employer’s, except cost reimbursement employers, taxable wage rate shall be determined in the manner set forth in this subsection for each calendar year:
(a)(i) Each eligible employer shall be given an "experience factor" which shall be the ratio of excess of contributions over benefits paid on the employer’s account since December 31, 1939, to his average annual taxable payroll rounded to the next lower dollar amount for the four (4) fiscal years immediately preceding the computation date, except that when an employer first becomes eligible, his "experience factor" will be computed on his average annual taxable payroll for the two (2) fiscal years or more, but not to exceed four (4) fiscal years, immediately preceding the computation date. The computation of such "experience factor" shall be to six (6) decimal places.
(ii) Each deficit employer shall be given a "deficit experience factor" which shall be the ratio of excess of benefits paid on the employer’s account over contributions since December 31, 1939, to his average annual taxable payroll rounded to the next lower dollar amount for one (1) or more fiscal years, but not to exceed four (4) fiscal years, for which he had covered employment ending on the computation date; provided, however, that any employer who, on any computation date has a "deficit experience factor" for the period immediately preceding such computation date but who has filed all reports, paid all contributions and penalties due on or before the cutoff date, and has during the last four (4) fiscal years paid contributions at a rate of not less than the standard rate applicable for each such year and in excess of benefits charged to his experience rating account during such years, shall have any balance of benefits charged to his account, which on the computation date immediately preceding such four (4) fiscal years was in excess of contributions paid, deleted from his account, and the excess benefits so deleted shall not be considered in the computation of his taxable wage rate for the rate years following such four (4) fiscal years. For the rate year following such computation date, he shall be given the standard rate for that year.
(iii) In the event an employer’s coverage has been terminated because he has ceased to do business or because he has not had covered employment for a period of four (4) years, and if said employer thereafter becomes a covered employer, he will be considered as though he were a new employer, and he shall not be credited with his previous experience under this chapter for the purpose of computing any future "experience factor."
(iv) Benefits paid to a claimant whose employment terminated because the claimant’s employer was called to active military duty shall not be used as a factor in determining the taxable wage rate of that employer.
(b) Schedules shall be prepared listing all eligible employers in inverse numerical order of their experience factors, and all deficit employers in numerical order of their deficit experience factors. There shall be listed on such schedules for each such employer in addition to the experience factor: (i) the amount of his taxable payroll for the fiscal year ending on the computation date, and (ii) a cumulative total consisting of the sum of such employer’s taxable payroll for the fiscal year ending on the computation date and the corresponding taxable payrolls for all other employers preceding him on such schedules.
(c) The cumulative taxable payroll amounts listed on the schedules provided for in paragraph (b) of this subsection shall be segregated into groups whose limits shall be those set out in the table provided in section 72-1350 (7), Idaho Code. Each of such groups shall be identified by the rate class number listed in the table which represents the percentage limits of each group. Each employer on the schedules shall be assigned a taxable wage rate in accordance with section 72-1350, Idaho Code.
(d)(i) If the grouping of rate classes requires the inclusion of exactly one-half (1/2) of an employer’s taxable payroll, the employer shall be assigned the lower of the two (2) rates designated for the two (2) classes in which the halves of his taxable payroll are so required.
(ii) If the group of rate classes requires the inclusion of a portion other than exactly one-half (1/2) of an employer’s taxable payroll, the employer shall be assigned the rate designated for the class in which the greater part of his taxable payroll is so required.
(iii) If one (1) or more employers on the schedules have experience factors identical to that of the last employer included in a particular rate class, all such employers shall be included in and assigned the taxable wage rate specified for such class, notwithstanding the provisions of paragraph (c) of this subsection.
(e) If the taxable payroll amount or the experience factor or both such taxable payroll amount and experience factor of any eligible or deficit employer listed on the schedules is changed, the employer shall be placed in that position on the schedules which he would have occupied had his taxable payroll amount and/or experience factor as changed been used in determining his position in the first instance, but such change shall not affect the position or rate classification of any other employer listed on the schedules and shall not affect the rate determination for previous years.
(2) For experience rating purposes, all previously accumulated benefit charges to covered employers’ accounts, except cost reimbursement employers, shall not be changed except as provided in this chapter. Benefits paid prior to June 30 shall, as of June 30 of each year preceding the calendar year for which a covered employer’s taxable wage rate is effective, be charged to the account of the covered employer, except cost reimbursement employers, who paid the largest individual amount of base period wages as shown on the determination used as the basis for the payment of such benefits, except that no charge shall be made to the account of such covered employer with respect to benefits paid under the following situations:
(a) If paid to a worker who terminated his services voluntarily without good cause attributable to such covered employer, with good cause but for reasons not attributable to such covered employer, or who had been discharged for workplace misconduct in connection with such services;
(b) If paid in accordance with the provisions of section 72-1368 (10), Idaho Code, and the decision to pay benefits is subsequently reversed;
(c) For that portion of benefits paid to multistate claimants pursuant to section 72-1344, Idaho Code, which exceeds the amount of benefits that would have been charged had only Idaho wages been used in paying the claim;
(d) If paid in accordance with the extended benefit program triggered by either national or state indicators;
(e) If paid to a worker who continues to perform services for such covered employer without a reduction in his customary work schedule, and who is eligible to receive benefits due to layoff or a reduction in earnings from another employer; or
(f) If paid to a worker who turns down an offer of suitable work because of participation in a job training program pursuant to the requirements of section 72-1366 (8), Idaho Code.
(3) A covered employer whose experience rating account is chargeable, as prescribed by this section, is an interested party as defined in section 72-1323, Idaho Code. A determination of chargeability shall become final unless, within fourteen (14) days after notice as provided in section 72-1368 (5), Idaho Code, an appeal is filed by an interested party with the department in accordance with the department’s rules. Appeal proceedings shall be in accordance with the provisions of section 72-1361, Idaho Code.
(4)(a) An experience rating record shall be maintained for each covered employer. The record shall be credited with all contributions which the covered employer has paid for covered employment prior to the cutoff date, pursuant to the provisions of this and preceding acts, and which covered employment occurred prior to the computation date. The record shall also be charged with the amount of benefits paid which are chargeable to the covered employer’s account as provided by the appropriate provisions of the employment security law and regulations thereunder in effect at the time such benefits were paid. Nothing in this section shall be construed to grant any covered employer or individual in his service a priority with respect to any claim or right because of amounts paid by such covered employer into the employment security fund.
(b) Except those meeting the requirements of section 72-1349B, Idaho Code, each person or entity paying wages directly, or indirectly through arrangements in which payroll is consolidated for multiple persons or entities, shall maintain separate records and shall report the wages in accordance with this chapter. The wages for one (1) person or entity may not be reported under the assigned record of another, even where the people or entities are related.
(5)(a) Whenever any individual or type of organization, whether or not a covered employer within the meaning of section 72-1315, Idaho Code, in any manner succeeds to, or acquires all or substantially all, of the business of an employer who at the time of acquisition was a covered employer, and in respect to whom the director finds that the business of the predecessor is continued solely by the successor, the separate experience rating account of the predecessor shall, upon the joint application of the predecessor and the successor within the one hundred eighty (180) days after such acquisition and approval by the director, be transferred to the successor employer for the purpose of determining such successor’s liability and taxable wage rate, and any successor who was not an employer on the date of acquisition shall, as of such date, become a covered employer as defined in this chapter. Such one hundred eighty (180) day period may be extended at the discretion of the director.
(b) Whenever any individual or type of organization, whether or not a covered employer within the meaning of section 72-1315, Idaho Code, in any manner succeeds to, or acquires, part of the business of an employer who at the time of acquisition was a covered employer, and such portion of the business is continued by the successor, so much of the separate experience rating account of the predecessor as is attributable to the portion of the business transferred, as determined on a pro rata basis in the same ratio that the wages of covered employees properly allocable to the transferred portion of the business bears to the payroll of the predecessor in the last four (4) completed calendar quarters immediately preceding the date of transfer, shall, upon the joint application of the predecessor and the successor within one hundred eighty (180) days after such acquisition and approval by the director, be transferred to the successor employer for the purpose of determining such successor’s liability and taxable wage rate, and any successor who was not an employer on the date of acquisition shall, as of such date, become a covered employer as defined in this chapter. Such one hundred eighty (180) day period may be extended at the discretion of the director.
(c)(i) If the successor was a covered employer prior to the date of the acquisition of all or a part of the predecessor’s business, his taxable wage rate, effective the first day of the calendar quarter immediately following the date of acquisition, shall be a newly computed rate based on the combined experience of the predecessor and successor, the resulting rate remaining in effect the balance of the rate year.
(ii) If the successor was not a covered employer prior to the date of the acquisition of all or a part of the predecessor’s business, his rate shall be the rate applicable to the predecessor with respect to the period immediately preceding the date of acquisition, but if there was more than one (1) predecessor, the successor’s rate shall be a newly computed rate based on the combined experience of the predecessors, becoming effective immediately after the date of acquisition, and shall remain in effect the balance of the rate year.
(d) For purposes of this section, an employer’s experience rating account shall consist of the actual contribution, benefit and taxable payroll experience of the employer and any amounts due from the employer under this chapter. When a transferred experience rating account includes amounts due from the employer under this chapter, both the predecessor employer and the successor employer shall be jointly and severally liable for those amounts.
