First Calendar Year: 12% of the employer medical assistance wage base.
Second Calendar Year: 24% of the employer medical assistance wage base.
If otherwise liable for contributions under M.G.L. c. 149, § 189, the acquiring employer retains its employer medical assistance contributions rate for the remainder of the calendar year in which the acquisition takes place. The acquiring employer is allowed "credit" for employer medical assistance contributions paid by the acquired employer on employee wages prior to the acquisition. Beginning the January 1st following the acquisition, the higher of the two rate schedules that would have been applicable to the acquiring or acquired employer shall become the effective rate.
Following the acquisition, if some portion of the acquired employer still exists as a separate entity, that employer, if otherwise liable for contributions under M.G.L. c. 149, § 189, continues with the same rate that applied prior to the acquisition. Said employer would receive credit for payments made prior to the acquisition for any employees who remain with that employer.
