Employer and Member Contribution Rates

Each of the MPERA-administered retirement systems has specific contribution rates for employers and employees. Scroll down for rates

IMPORTANT - PERS employer and HPORS member contribution rates increase with the first July 2016 payroll report filed with MPERA.

Remember, you must report each payroll according to the “regularly occurring payday” originally provided to MPERA. Changes to this schedule are only allowed for extenuating circumstances. This is especially important this fiscal year end with the changing of employer and employee contribution rates. “The required contribution rate is the rate in effect at the time the employees are paid, and not the contribution rate in effect when the compensation was earned.” See ARM 2.43.2114.

Varying from your regular reporting schedule can affect your employees' service credit and membership service resulting in a negative impact to your employees' benefit at retirement. It also has an unfavorable impact on the plan's unfunded liability when correct contributions are not paid. Therefore, if your employees receive their paycheck in July, reporting July's payroll in June does not change the employer's obligation to withhold and submit contributions at the new rates.
