(c) When the eligible individual's separating employer is a covered contribution paying base year employer, benefits paid to the eligible individual shall be charged to the experience rating account of only the individual's separating employer if: (i) The individual qualifies for benefits under RCW 50.20.050 (1)(b)(i) or (2)(b)(i), as applicable, and became unemployed after having worked and earned wages in the bona fide work; (ii) The individual qualifies for benefits under RCW 50.20.050 (1)(b) (v) through (x) or (2)(b) (v) through (x); or (iii) During a public health emergency, the claimant worked at a health care facility as defined in RCW 9A.50.010 , was directly involved in the delivery of health services, and was terminated from work due to entering quarantine because of exposure to or contracting the disease that is the subject of the declaration of the public health emergency.

In addition to other circumstances identified by the department by rule, an individual who leaves the employ of such employer under the circumstances described in RCW 50.20.050 (1)(b) (iv) or (xi), (2)(b) (iv), (xi), or (xii), or (3) must be deemed to have left their employ for reasons not attributable to the employer; (ii) Was discharged for misconduct or gross misconduct connected with his or her work not a result of inability to meet the minimum job requirements; (iii) Is unemployed as a result of closure or severe curtailment of operation at the employer's plant, building, worksite, or other facility.

(b) The employer requesting relief of charges under this subsection must request relief in writing within 30 days following mailing to the last known address of the notification of the valid initial determination of such claim, stating the date and reason for the separation or the circumstances of continued employment. The department may waive this time limitation for good cause. The commissioner, upon investigation of the request, shall determine whether relief should be granted. (4) When a benefit claim becomes invalid due to an amendment or adjustment of a report where the employer failed to report or inaccurately reported hours worked or remuneration paid, or both, all benefits paid will be charged to the experience rating account of the contribution paying employer or employers that originally filed the incomplete or inaccurate report or reports. An employer who reimburses the trust fund for benefits paid to workers and who fails to report or inaccurately reported hours worked or remuneration paid, or both, shall reimburse the trust fund for all benefits paid that are based on the originally filed incomplete or inaccurate report or reports.

The commissioner has the authority to determine whether the employer has good cause under this subsection.

The commissioner has the authority to determine whether the employer has good cause under this subsection.

(ii) Each employer in the array shall be assigned to one of forty rate classes according to his or her benefit ratio as follows, and, except as provided in RCW 50.29.026 , the array calculation factor rate for each employer in the array shall be the rate specified in the rate class to which the employer has been assigned: Benefit Ratio Rate Class Rate (percent) At least Less than 0.000001 1 0.00 0.000001 0.001250 2 0.11 0.001250 0.002500 3 0.22 0.002500 0.003750 4 0.33 0.003750 0.005000 5 0.43 0.005000 0.006250 6 0.54 0.006250 0.007500 7 0.65 0.007500 0.008750 8 0.76 0.008750 0.010000 9 0.88 0.010000 0.011250 10 1.01 0.011250 0.012500 11 1.14 0.012500 0.013750 12 1.28 0.013750 0.015000 13 1.41 0.015000 0.016250 14 1.54 0.016250 0.017500 15 1.67 0.017500 0.018750 16 1.80 0.018750 0.020000 17 1.94 0.020000 0.021250 18 2.07 0.021250 0.022500 19 2.20 0.022500 0.023750 20 2.38 0.023750 0.025000 21 2.50 0.025000 0.026250 22 2.63 0.026250 0.027500 23 2.75 0.027500 0.028750 24 2.88 0.028750 0.030000 25 3.00 0.030000 0.031250 26 3.13 0.031250 0.032500 27 3.25 0.032500 0.033750 28 3.38 0.033750 0.035000 29 3.50 0.035000 0.036250 30 3.63 0.036250 0.037500 31 3.75 0.037500 0.040000 32 4.00 0.040000 0.042500 33 4.25 0.042500 0.045000 34 4.50 0.045000 0.047500 35 4.75 0.047500 0.050000 36 5.00 0.050000 0.052500 37 5.15 0.052500 0.055000 38 5.25 0.055000 0.057500 39 5.30 0.057500 40 5.40 (b) The graduated social cost factor rate shall be determined as follows: (i)(A) Except as provided in (b)(i)(B) and (C) of this subsection, the commissioner shall calculate the flat social cost factor for a rate year by dividing the total social cost by the total taxable payroll. The division shall be carried to the second decimal place with the remaining fraction disregarded unless it amounts to five hundredths or more, in which case the second decimal place shall be rounded to the next higher digit. The flat social cost factor shall be expressed as a percentage. (B)(I) If, on the cut-off date, the balance in the unemployment compensation fund is determined by the commissioner to be an amount that will provide more than ten months of unemployment benefits, the commissioner shall calculate the flat social cost factor for the rate year immediately following the cut-off date by reducing the total social cost by the dollar amount that represents the number of months for which the balance in the unemployment compensation fund on the cut-off date will provide benefits above ten months and dividing the result by the total taxable payroll. However, the calculation under this subsection (1)(b)(i)(B) for a rate year may not result in a flat social cost factor that is more than four-tenths lower than the calculation under (b)(i)(A) of this subsection for that rate year. For rate year 2011 and thereafter, the calculation may not result in a flat social cost factor that is more than one and twenty-two one-hundredths percent except for rate year 2021 the calculation may not result in a flat social cost factor that is more than five-tenths percent, for rate year 2022 the calculation may not result in a flat social cost factor that is more than five-tenths percent, for rate year 2023 the calculation may not result in a flat social cost factor that is more than seven-tenths percent, for rate year 2024 the calculation may not result in a flat social cost factor that is more than eighty-five one-hundredths percent, and for rate year 2025 the calculation may not result in a flat social cost factor that is more than nine-tenths percent. (II) If, on the cut-off date, the balance in the unemployment compensation fund is determined by the commissioner to be an amount that will provide ten months of unemployment benefits or less, the flat social cost factor for the rate year immediately following the cut-off date may not increase by more than fifty percent over the previous rate year or may not exceed one and twenty-two one-hundredths percent, whichever is greater. (III) For the purposes of this subsection (1)(b), the commissioner shall determine the number of months of unemployment benefits in the unemployment compensation fund using the benefit cost rate for the average of the three highest calendar benefit cost rates in the twenty consecutive completed calendar years immediately preceding the cut-off date or a period of consecutive calendar years immediately preceding the cut-off date that includes three recessions, if longer. (C) The minimum flat social cost factor calculated under this subsection (1)(b) shall be six-tenths of one percent, except that if the balance in the unemployment compensation fund is determined by the commissioner to be an amount that will provide: (I) At least ten months but less than eleven months of unemployment benefits, the minimum shall be five-tenths of one percent; or (II) At least eleven months but less than twelve months of unemployment benefits, the minimum shall be forty-five hundredths of one percent; or (III) At least twelve months but less than thirteen months of unemployment benefits, the minimum shall be four-tenths of one percent; or (IV) At least thirteen months but less than fifteen months of unemployment benefits, the minimum shall be thirty-five hundredths of one percent; or (V) At least fifteen months but less than seventeen months of unemployment benefits, the minimum shall be twenty-five hundredths of one percent; or (VI) At least seventeen months but less than eighteen months of unemployment benefits, the minimum shall be fifteen hundredths of one percent; or (VII) At least eighteen months of unemployment benefits, the minimum shall be fifteen hundredths of one percent through rate year 2011 and shall be zero thereafter. (ii) The graduated social cost factor rate for each employer in the array is the flat social cost factor multiplied by the percentage specified as follows for the rate class to which the employer has been assigned in (a)(ii) of this subsection, except that the sum of an employer's array calculation factor rate and the graduated social cost factor rate may not exceed six percent or, for employers whose North American industry classification system code is within "111," "112," "1141," "115," "3114," "3117," "42448," or "49312," may not exceed five and four-tenths percent: (A) Rate class 1 - 40 percent; (B) Rate class 2 - 44 percent; (C) Rate class 3 - 48 percent; (D) Rate class 4 - 52 percent; (E) Rate class 5 - 56 percent; (F) Rate class 6 - 60 percent; (G) Rate class 7 - 64 percent; (H) Rate class 8 - 68 percent; (I) Rate class 9 - 72 percent; (J) Rate class 10 - 76 percent; (K) Rate class 11 - 80 percent; (L) Rate class 12 - 84 percent; (M) Rate class 13 - 88 percent; (N) Rate class 14 - 92 percent; (O) Rate class 15 - 96 percent; (P) Rate class 16 - 100 percent; (Q) Rate class 17 - 104 percent; (R) Rate class 18 - 108 percent; (S) Rate class 19 - 112 percent; (T) Rate class 20 - 116 percent; and (U) Rate classes 21 through 40 - 120 percent. (iii) For rate year 2023, for any employer with 10 or fewer employees as reported on the employer's fourth quarter report to the department for 2021 and whose rate class is greater than rate class 7, the employer's rate class, only for purposes of the rate classes in (b)(ii)(A) through (U) of this subsection (1), is rate class 7. (iv) For the purposes of this section: (A) "Total social cost" means the amount calculated by subtracting the array calculation factor contributions paid by all employers with respect to the four consecutive calendar quarters immediately preceding the computation date and paid to the employment security department by the cut-off date from the total unemployment benefits paid to claimants in the same four consecutive calendar quarters. (B) "Total taxable payroll" means the total amount of wages subject to tax, as determined under RCW 50.24.010 , for all employers in the four consecutive calendar quarters immediately preceding the computation date and reported to the employment security department by the cut-off date. (c) For employers who do not meet the definition of "qualified employer" by reason of failure to pay contributions when due: (i)(A) For an employer who does not enter into an approved agency-deferred payment contract as described in (c)(i)(B) or (C) of this subsection, the array calculation factor rate shall be the rate it would have been if the employer had not been delinquent in payment plus an additional one percent or, if the employer is delinquent in payment for a second or more consecutive year, an additional two percent; (B) For an employer who enters an approved agency-deferred payment contract by September 30th of the previous rate year, the array calculation factor rate shall be the rate it would have been if the employer had not been delinquent in payment; (C) For an employer who enters an approved agency-deferred payment contract after September 30th of the previous rate year, but within thirty days of the date the department sent its first tax rate notice, the array calculation factor rate shall be the rate it would have been had the employer not been delinquent in payment plus an additional one-half of one percent or, if the employer is delinquent in payment for a second or more consecutive year, an additional one and one-half percent; (D) For an employer who enters an approved agency-deferred payment contract as described in (c)(i)(B) or (C) of this subsection, but who fails to make any one of the succeeding deferred payments or fails to submit any succeeding tax report and payment in a timely manner, the array calculation factor rate shall immediately revert to the applicable array calculation factor rate under (c)(i)(A) of this subsection; and (ii) The social cost factor rate shall be the social cost factor rate assigned to rate class 40 under (b)(ii) of this subsection. (d) For all other employers not qualified to be in the array: (i) The array calculation factor rate shall be a rate equal to the average industry array calculation factor rate as determined by the commissioner, multiplied by the history factor, but not less than one percent or more than the array calculation factor rate in rate class 40; (ii) The social cost factor rate shall be a rate equal to the average industry social cost factor rate as determined by the commissioner, multiplied by the history factor, but not more than the social cost factor rate assigned to rate class 40 under (b)(ii) of this subsection; and (iii) The history factor shall be based on the total amounts of benefits charged and contributions paid in the three fiscal years ending prior to the computation date by employers not qualified to be in the array, other than employers in (c) of this subsection, who were first subject to contributions in the calendar year ending three years prior to the computation date. The commissioner shall calculate the history ratio by dividing the total amount of benefits charged by the total amount of contributions paid in this three-year period by these employers. The division shall be carried to the second decimal place with the remaining fraction disregarded unless it amounts to five one-hundredths or more, in which case the second decimal place shall be rounded to the next higher digit. The commissioner shall determine the history factor according to the history ratio as follows: History Ratio History Factor (percent) At least Less than (A) .95 90 (B) .95 1.05 100 (C) 1.05 115 (2) Assignment of employers by the commissioner to industrial classification, for purposes of this section, shall be in accordance with established classification practices found in the North American industry classification system code. (1) The contribution rate for each employer subject to contributions under RCW 50.24.010 shall be the sum of the array calculation factor rate and the graduated social cost factor rate determined under this subsection, and the solvency surcharge determined under RCW 50.29.041 , if any. (a) The array calculation factor rate shall be determined as follows: (i) An array shall be prepared, listing all qualified employers in ascending order of their benefit ratios. The array shall show for each qualified employer: (A) Identification number; (B) benefit ratio; and (C) taxable payrolls for the four consecutive calendar quarters immediately preceding the computation date and reported to the employment security department by the cut-off date. (ii) Each employer in the array shall be assigned to one of forty rate classes according to his or her benefit ratio as follows, and, except as provided in RCW 50.29.026 , the array calculation factor rate for each employer in the array shall be the rate specified in the rate class to which the employer has been assigned: Benefit Ratio Rate Class Rate (percent) At least Less than 0.000001 1 0.00 0.000001 0.001250 2 0.11 0.001250 0.002500 3 0.22 0.002500 0.003750 4 0.33 0.003750 0.005000 5 0.43 0.005000 0.006250 6 0.54 0.006250 0.007500 7 0.65 0.007500 0.008750 8 0.76 0.008750 0.010000 9 0.88 0.010000 0.011250 10 1.01 0.011250 0.012500 11 1.14 0.012500 0.013750 12 1.28 0.013750 0.015000 13 1.41 0.015000 0.016250 14 1.54 0.016250 0.017500 15 1.67 0.017500 0.018750 16 1.80 0.018750 0.020000 17 1.94 0.020000 0.021250 18 2.07 0.021250 0.022500 19 2.20 0.022500 0.023750 20 2.38 0.023750 0.025000 21 2.50 0.025000 0.026250 22 2.63 0.026250 0.027500 23 2.75 0.027500 0.028750 24 2.88 0.028750 0.030000 25 3.00 0.030000 0.031250 26 3.13 0.031250 0.032500 27 3.25 0.032500 0.033750 28 3.38 0.033750 0.035000 29 3.50 0.035000 0.036250 30 3.63 0.036250 0.037500 31 3.75 0.037500 0.040000 32 4.00 0.040000 0.042500 33 4.25 0.042500 0.045000 34 4.50 0.045000 0.047500 35 4.75 0.047500 0.050000 36 5.00 0.050000 0.052500 37 5.15 0.052500 0.055000 38 5.25 0.055000 0.057500 39 5.30 0.057500 40 5.40 Benefit Ratio Rate Class Rate (percent) At least Less than 0.000001 1 0.00 0.000001 0.001250 2 0.11 0.001250 0.002500 3 0.22 0.002500 0.003750 4 0.33 0.003750 0.005000 5 0.43 0.005000 0.006250 6 0.54 0.006250 0.007500 7 0.65 0.007500 0.008750 8 0.76 0.008750 0.010000 9 0.88 0.010000 0.011250 10 1.01 0.011250 0.012500 11 1.14 0.012500 0.013750 12 1.28 0.013750 0.015000 13 1.41 0.015000 0.016250 14 1.54 0.016250 0.017500 15 1.67 0.017500 0.018750 16 1.80 0.018750 0.020000 17 1.94 0.020000 0.021250 18 2.07 0.021250 0.022500 19 2.20 0.022500 0.023750 20 2.38 0.023750 0.025000 21 2.50 0.025000 0.026250 22 2.63 0.026250 0.027500 23 2.75 0.027500 0.028750 24 2.88 0.028750 0.030000 25 3.00 0.030000 0.031250 26 3.13 0.031250 0.032500 27 3.25 0.032500 0.033750 28 3.38 0.033750 0.035000 29 3.50 0.035000 0.036250 30 3.63 0.036250 0.037500 31 3.75 0.037500 0.040000 32 4.00 0.040000 0.042500 33 4.25 0.042500 0.045000 34 4.50 0.045000 0.047500 35 4.75 0.047500 0.050000 36 5.00 0.050000 0.052500 37 5.15 0.052500 0.055000 38 5.25 0.055000 0.057500 39 5.30 0.057500 40 5.40 (b) The graduated social cost factor rate shall be determined as follows: (i)(A) Except as provided in (b)(i)(B) and (C) of this subsection, the commissioner shall calculate the flat social cost factor for a rate year by dividing the total social cost by the total taxable payroll. The division shall be carried to the second decimal place with the remaining fraction disregarded unless it amounts to five hundredths or more, in which case the second decimal place shall be rounded to the next higher digit. The flat social cost factor shall be expressed as a percentage. (B)(I) If, on the cut-off date, the balance in the unemployment compensation fund is determined by the commissioner to be an amount that will provide more than ten months of unemployment benefits, the commissioner shall calculate the flat social cost factor for the rate year immediately following the cut-off date by reducing the total social cost by the dollar amount that represents the number of months for which the balance in the unemployment compensation fund on the cut-off date will provide benefits above ten months and dividing the result by the total taxable payroll. However, the calculation under this subsection (1)(b)(i)(B) for a rate year may not result in a flat social cost factor that is more than four-tenths lower than the calculation under (b)(i)(A) of this subsection for that rate year. For rate year 2011 and thereafter, the calculation may not result in a flat social cost factor that is more than one and twenty-two one-hundredths percent except for rate year 2021 the calculation may not result in a flat social cost factor that is more than five-tenths percent, for rate year 2022 the calculation may not result in a flat social cost factor that is more than five-tenths percent, for rate year 2023 the calculation may not result in a flat social cost factor that is more than seven-tenths percent, for rate year 2024 the calculation may not result in a flat social cost factor that is more than eighty-five one-hundredths percent, and for rate year 2025 the calculation may not result in a flat social cost factor that is more than nine-tenths percent. (II) If, on the cut-off date, the balance in the unemployment compensation fund is determined by the commissioner to be an amount that will provide ten months of unemployment benefits or less, the flat social cost factor for the rate year immediately following the cut-off date may not increase by more than fifty percent over the previous rate year or may not exceed one and twenty-two one-hundredths percent, whichever is greater. (III) For the purposes of this subsection (1)(b), the commissioner shall determine the number of months of unemployment benefits in the unemployment compensation fund using the benefit cost rate for the average of the three highest calendar benefit cost rates in the twenty consecutive completed calendar years immediately preceding the cut-off date or a period of consecutive calendar years immediately preceding the cut-off date that includes three recessions, if longer. (C) The minimum flat social cost factor calculated under this subsection (1)(b) shall be six-tenths of one percent, except that if the balance in the unemployment compensation fund is determined by the commissioner to be an amount that will provide: (I) At least ten months but less than eleven months of unemployment benefits, the minimum shall be five-tenths of one percent; or (II) At least eleven months but less than twelve months of unemployment benefits, the minimum shall be forty-five hundredths of one percent; or (III) At least twelve months but less than thirteen months of unemployment benefits, the minimum shall be four-tenths of one percent; or (IV) At least thirteen months but less than fifteen months of unemployment benefits, the minimum shall be thirty-five hundredths of one percent; or (V) At least fifteen months but less than seventeen months of unemployment benefits, the minimum shall be twenty-five hundredths of one percent; or (VI) At least seventeen months but less than eighteen months of unemployment benefits, the minimum shall be fifteen hundredths of one percent; or (VII) At least eighteen months of unemployment benefits, the minimum shall be fifteen hundredths of one percent through rate year 2011 and shall be zero thereafter. (ii) The graduated social cost factor rate for each employer in the array is the flat social cost factor multiplied by the percentage specified as follows for the rate class to which the employer has been assigned in (a)(ii) of this subsection, except that the sum of an employer's array calculation factor rate and the graduated social cost factor rate may not exceed six percent or, for employers whose North American industry classification system code is within "111," "112," "1141," "115," "3114," "3117," "42448," or "49312," may not exceed five and four-tenths percent: (A) Rate class 1 - 40 percent; (B) Rate class 2 - 44 percent; (C) Rate class 3 - 48 percent; (D) Rate class 4 - 52 percent; (E) Rate class 5 - 56 percent; (F) Rate class 6 - 60 percent; (G) Rate class 7 - 64 percent; (H) Rate class 8 - 68 percent; (I) Rate class 9 - 72 percent; (J) Rate class 10 - 76 percent; (K) Rate class 11 - 80 percent; (L) Rate class 12 - 84 percent; (M) Rate class 13 - 88 percent; (N) Rate class 14 - 92 percent; (O) Rate class 15 - 96 percent; (P) Rate class 16 - 100 percent; (Q) Rate class 17 - 104 percent; (R) Rate class 18 - 108 percent; (S) Rate class 19 - 112 percent; (T) Rate class 20 - 116 percent; and (U) Rate classes 21 through 40 - 120 percent. (iii) For rate year 2023, for any employer with 10 or fewer employees as reported on the employer's fourth quarter report to the department for 2021 and whose rate class is greater than rate class 7, the employer's rate class, only for purposes of the rate classes in (b)(ii)(A) through (U) of this subsection (1), is rate class 7. (iv) For the purposes of this section: (A) "Total social cost" means the amount calculated by subtracting the array calculation factor contributions paid by all employers with respect to the four consecutive calendar quarters immediately preceding the computation date and paid to the employment security department by the cut-off date from the total unemployment benefits paid to claimants in the same four consecutive calendar quarters. (B) "Total taxable payroll" means the total amount of wages subject to tax, as determined under RCW 50.24.010 , for all employers in the four consecutive calendar quarters immediately preceding the computation date and reported to the employment security department by the cut-off date. (c) For employers who do not meet the definition of "qualified employer" by reason of failure to pay contributions when due: (i)(A) For an employer who does not enter into an approved agency-deferred payment contract as described in (c)(i)(B) or (C) of this subsection, the array calculation factor rate shall be the rate it would have been if the employer had not been delinquent in payment plus an additional one percent or, if the employer is delinquent in payment for a second or more consecutive year, an additional two percent; (B) For an employer who enters an approved agency-deferred payment contract by September 30th of the previous rate year, the array calculation factor rate shall be the rate it would have been if the employer had not been delinquent in payment; (C) For an employer who enters an approved agency-deferred payment contract after September 30th of the previous rate year, but within thirty days of the date the department sent its first tax rate notice, the array calculation factor rate shall be the rate it would have been had the employer not been delinquent in payment plus an additional one-half of one percent or, if the employer is delinquent in payment for a second or more consecutive year, an additional one and one-half percent; (D) For an employer who enters an approved agency-deferred payment contract as described in (c)(i)(B) or (C) of this subsection, but who fails to make any one of the succeeding deferred payments or fails to submit any succeeding tax report and payment in a timely manner, the array calculation factor rate shall immediately revert to the applicable array calculation factor rate under (c)(i)(A) of this subsection; and (ii) The social cost factor rate shall be the social cost factor rate assigned to rate class 40 under (b)(ii) of this subsection. (d) For all other employers not qualified to be in the array: (i) The array calculation factor rate shall be a rate equal to the average industry array calculation factor rate as determined by the commissioner, multiplied by the history factor, but not less than one percent or more than the array calculation factor rate in rate class 40; (ii) The social cost factor rate shall be a rate equal to the average industry social cost factor rate as determined by the commissioner, multiplied by the history factor, but not more than the social cost factor rate assigned to rate class 40 under (b)(ii) of this subsection; and (iii) The history factor shall be based on the total amounts of benefits charged and contributions paid in the three fiscal years ending prior to the computation date by employers not qualified to be in the array, other than employers in (c) of this subsection, who were first subject to contributions in the calendar year ending three years prior to the computation date.

RCW 50.29.062 Contribution rates for predecessor and successor employers.

(1) If the department finds that a significant purpose of the transfer of the business is to obtain a reduced array calculation factor rate, contribution rates shall be computed and penalties and other sanctions shall apply as specified in RCW 50.29.063 . (2) If subsection (1) of this section and RCW 50.29.063 do not apply and if the department finds that an employer is a successor, or partial successor, to a predecessor business, predecessor and successor employer contribution rates shall be computed in the following manner: (a) If the successor is an employer, as defined in RCW 50.04.080 , at the time of the transfer of a business, the following applies: (i) The successor's contribution rate shall remain unchanged for the remainder of the rate year in which the transfer occurs. (ii) Beginning January 1st following the transfer, the successor's contribution rate for each rate year shall be based on a combination of the following: (A) The successor's experience with payrolls and benefits; and (B) Any experience assigned to the predecessor involved in the transfer. If only a portion of the business was transferred, then the experience attributable to the acquired portion is assigned to the successor. (b) If the successor is not an employer at the time of the transfer, the following applies: (i) Except as provided in (b)(ii) and (iii) of this subsection (2), the successor shall pay contributions: (A) At the contribution rate assigned to the predecessor employer at the time of the transfer for the remainder of that rate year. Any experience attributable to the predecessor relating to the assignment of the predecessor's rate class is transferred to the successor. (B) Beginning January 1st following the transfer, the successor's contribution rate for each rate year shall be based on an array calculation factor rate that is a combination of the following: The successor's experience with payrolls and benefits; and any experience assigned to the predecessor involved in the transfer. If only a portion of the business was transferred, then the experience attributable to the acquired portion is assigned to the successor if qualified under RCW 50.29.010 by including the transferred experience. If not qualified under RCW 50.29.010 , the contribution rate shall equal the sum of the rates determined by the commissioner under RCW 50.29.025 (1)(d) and 50.29.041 , if applicable, and continuing until the successor qualifies for a different rate, including the transferred experience. (ii) If there is a substantial continuity of ownership, control, or management by the successor of the business of the predecessor, the successor shall pay contributions at the contribution rate determined for the predecessor employer at the time of the transfer for the remainder of that rate year. Any experience attributable to the predecessor relating to the assignment of the predecessor's rate class is transferred to the successor. Beginning January 1st following the transfer, the successor's array calculation factor rate shall be based on a combination of the transferred experience of the acquired business and the successor's experience after the transfer. (iii) If the successor simultaneously acquires the business or a portion of the business of two or more employers with different contribution rates, the successor's rate, from the date the transfer occurred until the end of that rate year and until it qualifies in its own right for a new rate, shall be the sum of the rates determined by the commissioner under RCW 50.29.025 (1) (a) and (b) and 50.29.041 , applicable at the time of the acquisition, to the predecessor employer who, among the parties to the acquisition, had the largest total payroll in the completed calendar quarter immediately preceding the date of transfer, but not less than the sum of the rates determined by the commissioner under RCW 50.29.025 (1)(d) and 50.29.041 , if applicable. (c) With respect to predecessor employers: (i) The contribution rate on any payroll retained by a predecessor employer shall remain unchanged for the remainder of the rate year in which the transfer occurs. (ii) In all cases, beginning January 1st following the transfer, the predecessor's contribution rate or the predecessor's array calculation factor for each rate year shall be based on its experience with payrolls and benefits as of the regular computation date for that rate year excluding the experience of the transferred business or transferred portion of business as that experience has transferred to the successor: PROVIDED, That if all of the predecessor's business is transferred to a successor or successors, the predecessor shall not be a qualified employer until it satisfies the requirements of a "qualified employer" as set forth in RCW 50.29.010 . (3) A predecessor-successor relationship does not exist for purposes of subsection (2) of this section when a significant purpose of the transfer of a business or its operating assets is for the employer to move or expand an existing business, or for an employer to establish a substantially similar business under common ownership, management, and control. However, if an employer transfers its business to another employer, and both employers are at the time of transfer under substantially common ownership, management, or control, then the unemployment experience attributable to the transferred business shall also be transferred to, and combined with the unemployment experience attributable to, the employer to whom such business is so transferred as specified in subsection (2)(a) of this section. (4) For purposes of this section, "transfer of a business" means the same as RCW 50.29.063 (4)(c). (1) If the department finds that a significant purpose of the transfer of the business is to obtain a reduced array calculation factor rate, contribution rates shall be computed and penalties and other sanctions shall apply as specified in RCW 50.29.063 . (2) If subsection (1) of this section and RCW 50.29.063 do not apply and if the department finds that an employer is a successor, or partial successor, to a predecessor business, predecessor and successor employer contribution rates shall be computed in the following manner: (a) If the successor is an employer, as defined in RCW 50.04.080 , at the time of the transfer of a business, the following applies: (i) The successor's contribution rate shall remain unchanged for the remainder of the rate year in which the transfer occurs. (ii) Beginning January 1st following the transfer, the successor's contribution rate for each rate year shall be based on a combination of the following: (A) The successor's experience with payrolls and benefits; and (B) Any experience assigned to the predecessor involved in the transfer. If only a portion of the business was transferred, then the experience attributable to the acquired portion is assigned to the successor. (b) If the successor is not an employer at the time of the transfer, the following applies: (i) Except as provided in (b)(ii) and (iii) of this subsection (2), the successor shall pay contributions: (A) At the contribution rate assigned to the predecessor employer at the time of the transfer for the remainder of that rate year. Any experience attributable to the predecessor relating to the assignment of the predecessor's rate class is transferred to the successor. (B) Beginning January 1st following the transfer, the successor's contribution rate for each rate year shall be based on an array calculation factor rate that is a combination of the following: The successor's experience with payrolls and benefits; and any experience assigned to the predecessor involved in the transfer. If only a portion of the business was transferred, then the experience attributable to the acquired portion is assigned to the successor if qualified under RCW 50.29.010 by including the transferred experience. If not qualified under RCW 50.29.010 , the contribution rate shall equal the sum of the rates determined by the commissioner under RCW 50.29.025 (1)(d) and 50.29.041 , if applicable, and continuing until the successor qualifies for a different rate, including the transferred experience. (ii) If there is a substantial continuity of ownership, control, or management by the successor of the business of the predecessor, the successor shall pay contributions at the contribution rate determined for the predecessor employer at the time of the transfer for the remainder of that rate year. Any experience attributable to the predecessor relating to the assignment of the predecessor's rate class is transferred to the successor. Beginning January 1st following the transfer, the successor's array calculation factor rate shall be based on a combination of the transferred experience of the acquired business and the successor's experience after the transfer. (iii) If the successor simultaneously acquires the business or a portion of the business of two or more employers with different contribution rates, the successor's rate, from the date the transfer occurred until the end of that rate year and until it qualifies in its own right for a new rate, shall be the sum of the rates determined by the commissioner under RCW 50.29.025 (1) (a) and (b) and 50.29.041 , applicable at the time of the acquisition, to the predecessor employer who, among the parties to the acquisition, had the largest total payroll in the completed calendar quarter immediately preceding the date of transfer, but not less than the sum of the rates determined by the commissioner under RCW 50.29.025 (1)(d) and 50.29.041 , if applicable. (c) With respect to predecessor employers: (i) The contribution rate on any payroll retained by a predecessor employer shall remain unchanged for the remainder of the rate year in which the transfer occurs. (ii) In all cases, beginning January 1st following the transfer, the predecessor's contribution rate or the predecessor's array calculation factor for each rate year shall be based on its experience with payrolls and benefits as of the regular computation date for that rate year excluding the experience of the transferred business or transferred portion of business as that experience has transferred to the successor: PROVIDED, That if all of the predecessor's business is transferred to a successor or successors, the predecessor shall not be a qualified employer until it satisfies the requirements of a "qualified employer" as set forth in RCW 50.29.010 . (3) A predecessor-successor relationship does not exist for purposes of subsection (2) of this section when a significant purpose of the transfer of a business or its operating assets is for the employer to move or expand an existing business, or for an employer to establish a substantially similar business under common ownership, management, and control. However, if an employer transfers its business to another employer, and both employers are at the time of transfer under substantially common ownership, management, or control, then the unemployment experience attributable to the transferred business shall also be transferred to, and combined with the unemployment experience attributable to, the employer to whom such business is so transferred as specified in subsection (2)(a) of this section. (4) For purposes of this section, "transfer of a business" means the same as RCW 50.29.063 (4)(c).
