PURPOSE: This rule sets forth the method and deadline for
payments by employers as provided by section 169.620, RSMo.
(1) Each employer reporting to The Public Education Employee
Retirement System of Missouri shall report required data on
employees and all contributions to the retirement system using
the Online Automated System Integrated Solution (OASIS).
(2) Employers shall use OASIS to report salary payments made
to all employees, contributions withheld from employees
included in the retirement system, and supporting information
required by the board of trustees. Transmission of data must be
sent to the board of trustees no later than ten (10) working days
after the last day of each calendar month of the school year in
which salaries are paid.
(3) Employers of persons included in the retirement system
shall withhold from each salary payment issued to such persons
during the school year in which the services are rendered an
amount which is the percent of salary rate required by the
contribution rate then in effect, and employers shall transmit
to the board of trustees, not later than ten (10) days after the
last day of each calendar month of the school year, twice the
amount withheld during the month. Salary shall be reported
for the school year when the salary is earned, not when the
salary is paid.
(4) All deductions of contributions from salary payments made
by employers for the retirement system are declared and shall
be considered to be funds belonging to the retirement system,
and no employer shall refund or repay any contributions or any
part of any contributions so deducted to any employee for any
cause but shall transmit all contributions deducted, together
with an equal amount, to the board of trustees, which board
shall settle all claims against funds so deducted.
(5) All contributions withheld from salaries paid to members
along with an equal contribution of the employer shall be
transmitted to the board of trustees by check, bank draft,
electronic funds transfer, or any negotiable instrument
collectible at par through a bank in the state of Missouri, made
payable to The Public Education Employee Retirement System
of Missouri.
(6) If remittance for the full amount of both employee’s and
employer’s contributions which are due the retirement system
is not received in accordance with these regulations, it shall be
considered a failure or refusal by the employer to transmit such
amount and suit for recovery of the amount may be instituted
as provided for in section 169.620, RSMo.
(7) Errors by employers in reporting of eligibility for membership,
assigning of employees, and in remitting of contributions will
be corrected retroactively, provided the employer certifies that
an error was made, provides evidence adequate to support the
correction, and remits any balance due from the employer and
employee. If the employer has overremitted, the amount of
the employer’s portion of the overpayments will be credited to
the employer to be applied against future contributions. The
amount withheld by the employer from the employee shall
be refunded to the employee in a manner consistent with the
Internal Revenue Code.
(8) Any refund of contributions remitted in error for a member
or an employee shall include the total interest, if any, which
was credited to those contributions by the retirement system.
Any credit provided to the employer for matching employer
contributions required in such an instance shall be equal to
the total amount paid to the member or employee, including
interest. Any correcting remittance of contributions for a
member shall include the total interest, if any, which would
have been credited to those contributions by the retirement
system had the contributions been remitted on a correct and
timely basis. Any matching employer contribution remitted in
such an instance shall be equal to the total amount remitted
for the member, including interest.
(9) For purposes of determining retirement contributions and
benefits, salary rate includes medical insurance premiums
(including dental and vision) paid by the employer on behalf
of the member and payments made by the employer on
behalf of the member to a self-funded medical benefits plan.
The employer shall withhold from the member’s salary and
remit to the system contributions on any such premiums and
payments, along with matching employer contributions. The
payment reported for each member covered by a self-funded
medical benefits plan shall be determined by the employer.
(A) Salary rate also includes payments made by the employer
on behalf of the member to purchase an annuity, or fund a
deferred compensation plan, in lieu of medical insurance or a
self-funded medical benefits plan.
(B) Premiums and payments for prescription drug, life, and
other ancillary benefits determined separately from premiums
and payments for general medical benefits are not part of
salary rate.
(C) Beginning July 1, 2017, premiums paid by the employer on
behalf of the member and payments made by the employer on
behalf of the member to a self-funded medical benefits plan for
prescription drug coverage shall be included in salary rate as
defined in section 169.600, RSMo, whether or not such premiums
or payments for prescription drug coverage were determined
separately from premiums and payments for general medical
benefits. Contributions transmitted to the retirement system
before July 1, 2017, based on salary rates which either included
or excluded employer-paid premiums or payments to a selffunded medical benefits plan for prescription drug coverage
for members shall be deemed to have been in compliance with
this section. The retirement system shall not refund or adjust
contributions or adjust benefit determinations with respect to
any period before July 1, 2017, solely because of the treatment of
employer-paid premiums or payments to a self-funded medical
benefits plan for prescription drug coverage for members.
(D) Beginning July 1, 2020, certain payments made by
the employer on behalf of the member to a Health Savings
Account (HSA) shall be included in salary rate as defined in
section 169.600, RSMo, whether or not such payments were
determined separately from premiums and payments for
general medical benefits. Payments made by an employer
to a member’s HSA shall be included in salary rate up to the
amount that is offered to all employer’s employees and not
to exceed the applicable annual HSA contribution limit set
by Internal Revenue Code for single coverage. If a member
elects family medical coverage premium for the member
and for other members employed by the same employer, the
other members covered under this premium waive his or her
insurance coverage, and the employer pays HSA payments for
the member only, the employer shall report and remit to the
system contributions up to the amount of the HSA contribution
offered to all employer’s employees to the member paying the
family medical coverage and remaining amount for the other
members covered under the family medical coverage premium.
The annual contribution limit used will be the one in effect for
the calendar year in which a plan year begins. Contributions
transmitted to the retirement system before July 1, 2020, based
on salary rates which either included or excluded employer
payments to a member’s HSA shall be deemed to have been in
compliance with this section. The retirement system shall not
refund or adjust contributions or adjust benefit determinations
with respect to any period before July 1, 2020, solely because of
the treatment of employer-paid HSA contributions.
(E) Salary, salary rate, or compensation as defined in
section 169.600, RSMo, shall not be reduced due to premium
rebates or refunds received by the employer as a result of the
implementation of the “Patient Protection and Affordable Care
Act,” Public Law 111-148.
(F) If a member elects family medical coverage premium for
the member and for other members employed by the same
employer, the other members covered under this premium
waive his or her insurance coverage, and the employer pays
more than the individual medical premium rate when a mem
ber elects the family medical coverage premium, the employer
shall report and remit to the system contributions for the indi
vidual employee medical coverage premium for the member
paying the family medical coverage premium and remaining
amount for the other members covered under the family med
ical coverage premium.
(10) Retirement contributions which are withheld from com
pensation paid to members after June 30, 1989, shall be deemed
to have been picked up by the employer within the meaning
of Section 414(h)(2) of the Internal Revenue Code. The contribu
tions shall be withheld and credited to member accounts in
accordance with the provisions of sections 169.600–169.710,
RSMo, but shall be considered to have been picked up by the
employer solely for the purpose of sheltering the contributions
from federal income tax until paid by the retirement system in
the form of a refund or other benefits. The contributions shall
be subject to refund or benefit claims by either the member or
his/her surviving beneficiary in the same manner as any other
contributions in the member’s account with the retirement sys
tem. In reporting the contributions to the retirement system,
every employer included within the retirement system shall
certify that—1) the employee contributions were picked up by
the employer in lieu of being paid directly to the employees,
and 2) the employees had no option to receive the contribu
tions directly. The salary reported to the retirement system for
each employee shall include the contributions withheld, and
the total contributions withheld and reported shall equal the
percentage of that salary required under the then-prevailing
contribution rate. In withholding and reporting federal income
tax to taxing authorities, however, the employer shall exclude
from taxable compensation the retirement contributions with
held. Nothing in this rule shall be construed in any way as
affecting eligibility for, the amount of, or the process of paying
any refund or benefit payable to either the member or his/her
surviving beneficiary.
(11) The terms “salary,” “salary rate,” and “compensation” are
synonymous when used in regulations promulgated by the
board, unless the context plainly requires a different meaning.
(A) For purposes of calculating contributions and benefits,
those terms mean the regular remuneration earned by a
member as an employee of any covered district during a school
year, including (unless excluded by subsection (11)(B))—
1. Salary paid under the terms of the basic employment
agreement;
2. Wages, except as excluded in paragraphs (11)(B)6. and 9.;
3. Payments for extra duties, whether or not related to the
employee’s regular position. An activity is considered an extra
duty if it is set and approved by a school district’s Board of
Education except for any activity including but not limited to
fringe benefits, as defined under 16 CSR 10-6.020(11)(B);
4. Overtime payments;
5. Career ladder payments made pursuant to sections
168.500 to 168.515, RSMo;
6. Supplemental salary paid in addition to workers’
compensation;
7. Medical benefits as specified in section (9) of this rule;
8. Payment for annual leave, sick leave, or similar paid
leave actually used by the member;
9. Payment for leaves of absence if at least one hundred
percent (100%) of previous contract rate;
10. Compensation on which taxation is deferred under
Internal Revenue Code (IRC) section 401(k), 403(b), 457, 414(h)
(2), or similar plans established by the employer under the IRC;
11. Salary reductions for purposes of a plan established by
the employer under IRC section 125; and
12. Other similar payments that are earned by a member as
an employee of any other covered district during a school year.
(B) Salary, salary rate, and compensation do not include—
1. Payments for services as an independent contractor, or
any other payment that must be reported on IRS form 1099MISC;
2. Payments made by an entity that is not a covered
employer and reported to the IRS under that entity’s tax
identification number;
3. Payments made for unused annual, sick, or similar leave
time, except as provided by section 104.601, RSMo;
4. Payment for leaves of absence if less than one hundred
percent (100%) of previous contract rate, except as provided in
section 169.595, RSMo;
5. Extraordinary payments such as bonuses, awards, and
retirement incentives;
6. Consideration for agreeing to terminate employment,
including retirement incentives, retirement or separation
notice incentives, or any other payment(s) received by an
employee in exchange for agreeing to terminate employment,
regardless of if the employee is required to also perform extra
duties as a condition of receiving the payment(s);
7. Fringe benefits, except medical benefits as described in
section (9) of this rule;
8. Any other payment that is not part of the regular
remuneration earned by a member as an employee of a
covered district during a school year;
9. Payments resulting from employment disputes including
severance pay, back pay awards, payments in settlement of
employment contract disputes, payments in consideration
for agreeing to terminate employment, and payments in
settlement of other employment disputes; and
10. Any salary, wages, payments, benefits, or compensation
not included in subsection (11)(A).
(C) While an individual is employed in a position covered
by the system, compensation received from all employers
participating in the system will be used to determine
contributions and benefits. Compensation includes payments
for services rendered during the regular school session,
summer school, or interim periods. Individuals may not have
compensation covered by both Public School Retirement
System (PSRS) and Public Education Employee Retirement
System (PEERS) for the same period, provided individuals who
contributed to both systems on compensation for the same
period during the 1996–97 school year may elect in writing to
continue that status. The election is irrevocable and must be
made before September 30, 1997. If an individual is employed in
a position covered by PEERS and concurrently takes a position
with a public community college under section 169.140, RSMo,
both positions including any non-certificated work shall
automatically be covered under PSRS unless the PEERS member
elects to remain with PEERS.
(D) In determining “final average salary” as defined in sec
tion 169.600, RSMo, the system will disregard any increase
in compensation in excess of twenty percent (20%) from one
(1) year to the next in the final average salary period. This
limit will not apply to increases due to bona fide changes in
position or employer, increases required by state statute, or
district-wide salary schedule adjustments for previously un
recognized education related service. A bona fide change in
position, for purposes of applying the final average salary cap
occurs in the following situations: 1) the essential duties of the
position held change, or 2) there is a permanent change in
hours mandated by the employer. A mere title change without
any of these factors does not constitute a bona fide change in
position, nor does the addition of extra duties as set forth in
subsection (11)(A).

Op. Atty. Gen. No. 224, Black (11-30-77). If an employer
participates in The Missouri Non-Teacher School Employee
Retirement System, employer may not withhold employer’s share
of contribution for full-time employee whose salary is funded
through the Comprehensive Employment and Training Act of 1973
until the employee’s retirement benefits vest. Also, the Retirement
System is not authorized to refund to an employer the employer’s
contributions attributable to any employee who terminates his/her
employment prior to the vesting of his/her benefits.
