Payment for Reinstatement and Credit Purchases
PURPOSE: This rule complies with provisions of Chapter 169,
RSMo, relating to the payments made of funds to the retirement
system for reinstating and purchasing credit.
(1) Payments to reinstate or to purchase credit shall be made
in a manner acceptable to the Public Education Employee
Retirement System of Missouri.
(A) Consistent with the Internal Revenue Code, the system
may accept rollovers and in-service trustee-to-trustee transfers
in payment for reinstatement and credit purchases provided
that acceptance of any funds from any such authorized plan
or account will not jeopardize the tax-qualified status of
the retirement system and the money is from one (1) of the
following:
1. A 401(a) tax-qualified plan (including a Keogh plan
which meets additional requirements pertaining to owneremployees);
2. A 401(k) profit-sharing plan;
3. A 403(a) qualified-annuity plan;
4. A 408(a) individual retirement account (IRA) or a 408(b)
individual retirement annuity to the extent that the IRA
contains funds that have not previously been taxed;
5. A 403(b) qualified plan;
6. A state and local government 457(b) qualified plan;
7. Such other plans or accounts as may be authorized as
a source of eligible funds under the Internal Revenue Code,
provided that the system shall not be obligated to accept any
funds from any such authorized plan or account if the funds
would jeopardize the tax-qualified status of the system; or
8. The member, if the amount was distributed to the
member from a qualified plan, is rolled over by the member
to the system within sixty (60) days of that distribution, and is
accompanied by proof of rollover eligibility.
(B) The retirement system will accept, pursuant to section
(1) above, only an amount of funds equal to or less than the
balance due, including interest, for the reinstatement or
purchase for which the member applied.
(2) The board of trustees prior to July 1 each year shall establish a
“purchase rate” of interest based upon the actuarially-assumed
annual rate of return on invested funds of the retirement
system. The purchase rate shall apply to any amount due for
reinstatement of credit or for the purchase of credit except as
otherwise specified by law.
(3) A purchase shall be effected by the member paying
to the retirement system the amount the member would
have contributed and the amount the employer would have
contributed had such member been an employee for the
number of years for which the member is electing to purchase
credit, and had the member’s compensation during such
period been the highest annual salary rate on record with the
retirement system on the date of election to purchase credit.
The contribution rate used in determining the amount to be
paid shall be the contribution rate in effect on the date of
election to purchase credit.
(4) A reinstatement shall be effected by the member paying
to the retirement system with interest the total amount of
accumulated contributions withdrawn by the member or
refunded to the member with respect to the service being
reinstated. A member may reinstate less than the total service
previously forfeited. If a member is retired on disability before
completing such payments, the balance due with interest
may be deducted from the member’s disability retirement
allowance.
(5) The total amount of any payments made on an application
for purchase or reinstatement that buys a minimum of oneone-hundred thousandth (0.00001) or more of credit shall be
credited to the member’s accumulated contributions no later
than the close of the school year in which payment is made in
full or upon termination of membership.
(6) If payment to reinstate or purchase credit for which
the member applies is not completed within the period,
established by law, or prior to termination of membership
within the retirement system, the amount paid will—a) be
refunded to the member if proportional credit is not allowable;
or b) be used to allow proportional credit where permissible,
based on the relationship between the total principal due
at application and the total of the payments applied to the
principal, and the total amount paid will be credited to the
member’s accumulated contributions. Unless proportional
credit is not allowed, only payments purchasing less than the
first one-one-hundred thousandth (0.00001) year of credit will
be refunded. No other refunds will be permitted except as
specifically stated in this regulation.
(7) If a member dies before retirement or retires on service or
disability retirement after having made partial payments but
not payment in full to reinstate or purchase credit, the partial
payments will be refunded to the member’s beneficiary or the
retiree if proportional credit is not allowable by law or by rule
of the board of trustees. If proportional credit is allowable,
the payments will be credited to the member’s accumulated
contributions and proportional credit will be allowed. If a
member retires on disability retirement before completing
payment for a reinstatement of credit only, the balance due
with interest shall be deducted from the disability retirement
allowance as provided by law. Only payments purchasing less
than first one-one-hundred thousandth (0.00001) year of credit
will be refunded.
(8) A member electing to reinstate or purchase membership
service credit authorized by the laws governing the retirement
system shall make the election to reinstate or purchase
credit on a form provided by the retirement system and the
reinstatement or purchase shall be effected through payment
to the retirement system within the time period prescribed by
law of the contributions due, together with interest computed
at the purchase rate set by the board of trustees, in accordance
with the provisions of 16 CSR 10-6.045(2).
(9) A member may not elect to purchase membership service
credit from any source if the purchase would result in the
member accruing more than one (1) year of membership
service credit for any school year except as a result of the
purchase of credit authorized by section 169.577, RSMo. Unless
required to be allowed under federal law, a member cannot
elect to purchase or claim credit for services outside of a
district included in this retirement system, or to reinstate credit
previously earned in this retirement system, for which the
member is receiving or for which the member may, without
additional services, become eligible to receive a benefit from
another retirement system.
(10) A member who applies to reinstate or purchase credit
must provide reliable documentation adequate to prove each
element required to qualify for the reinstatement or purchase
for which the member applies. Where the credit being
purchased is based on a period of employment or a period of
service covered by a retirement system, the documentation
must include confirmation by the employer or retirement
system of the relevant facts.
(11) Once a member has made application to reinstate or
purchase service credit, no additional application to reinstate
or purchase such credit may be filed for the same period of
employment unless the member terminates membership with
the retirement system and subsequently reestablishes such
membership.
(12) The purchase of creditable service pursuant to section
169.577, RSMo, shall be administered as follows:
(A) Any member will be considered “within five (5) years of
being eligible to retire with a retirement allowance” if that
person would be eligible to begin receiving a full or reduced
retirement allowance from The Public Education Employee
Retirement System, by virtue of accrual of five (5) or fewer
years of creditable service or the passage of five (5) or fewer
calendar years;
(B) The salary used in calculating the cost of creditable
service purchased pursuant to section 169.577, RSMo, is not
“compensation paid to a member” as that phrase is used in
section 169.600(7), RSMo, and shall not be used in determining
final average salary;
(C) Credit purchased shall be used for all purposes except
vesting;
(D) The cost of the purchase shall be calculated pursuant to
the provisions of 16 CSR 10-4.012;
(E) A purchase shall be made only in increments of at least
one-one-hundred thousandth (0.00001) year and may not
exceed five-tenths (0.5) year; and
(F) If the total payments made prior to termination of
membership with the retirement system are insufficient
to purchase all the credit for which the member applied,
proportional credit shall be allowed based upon the ratio
between the amount due for the entire period for which
election to purchase was made and the total amount of the
payments applied to reduce the principal amount due, but
only in increments of one-one-hundred thousandth (0.00001)
year. The amount of partial payments not used to purchase
credit or pay interest shall be refunded.
(13) Members electing to reinstate or purchase credit may make
payments in any amount and at any time during the period
allowed for payment.
(14) The following provisions shall apply to the purchase of
creditable service under section 105.691, RSMo:
(A) A member may elect to purchase creditable service under
section 105.691, RSMo, only if the member had previously
acquired creditable service in a retirement plan defined in
that section for the employment to which the election applies,
except that if the service did not meet the membership
requirements of the employer’s retirement plan or the
employer had no such retirement plan at the time the service
was rendered, but the service would otherwise have met the
membership requirements of this system as in effect when
the election is made, the member shall be eligible to purchase
such creditable service. The creditable service allowable shall
be determined in accordance with the provisions of section
105.691, RSMo, and the rules of the board of trustees; and
(B) A member who does not complete payment in full on
an application to purchase creditable service under section
105.691, RSMo, within the time limit prescribed by law may
reapply to purchase creditable service for that same period
of employment. The member may apply within the limits of
the law to purchase creditable service for any other period
of employment for which application to purchase creditable
service was not previously made.
(15) Unless otherwise required by law, membership service
credit purchased under the laws governing the retirement
system cannot be used to establish eligibility for benefits under
sections 169.600 to 169.715, RSMo, but such purchased credit
may be used in computing the value of any benefits to which a
member would otherwise qualify under those sections.
(16) Unless a different amount is required by law, members
must have accrued at least one (1) year of membership service
credit for employment in a position covered by the retirement
system in order to apply to purchase service credit.
(17) Unless otherwise required by law, if the total payments
made within the time allowed to purchase credit is insufficient
to purchase all the credit for which the member applied,
proportional credit shall be allowed based on the ratio between
the amount due for the entire period for which the member
applied and the total amount of the payments applied to
reduce the principal amount due.
(18) A member electing to purchase membership service credit
for service in the armed forces may purchase one (1) year of
credit for each twelve- (12-) month period of such service. For
any such period of service in the armed forces of less than
twelve (12) months, the member shall receive proportional
credit computed to the nearest one-one-hundred thousandth
(0.00001) of a year, provided that if the member entered active
duty in the armed forces no later than the date on which the
member’s services were to have begun under an employment
agreement with a district included in the retirement system,
and if the total period of active military service that year
would have entitled the member to a year of creditable service
had that service been rendered with the district, the member
shall be eligible to purchase a full year of credit. No more than
one (1) year of membership service credit shall be allowed for
service in the armed forces or for a combination of service in
the armed forces and actual service in a district included in the
retirement system, for any one (1) school year.
(19) The following provisions apply with respect to a purchase
of credit for maternity or paternity leave pursuant to section
169.655, RSMo:
(A) A period of leave shall be considered maternity or
paternity leave for which membership service credit may be
purchased if—
1. The leave was unpaid;
2. The leave related to a natural birth or legal adoption;
3. The member was employed in a position covered by
The Public Education Employee Retirement System at the time
the leave relating to the initial natural birth or legal adoption
began;
4. The member provides written confirmation that the
leave was maternity or paternity leave;
5. The member provides a copy of a birth certificate, cer
tification of adoption, or physician’s certification which indi
cates that the event occurred within a reasonable time before
or after the period of maternity or paternity leave began; and
6. The member returns to employment in a position cov
ered by The Public Education Employee Retirement System;
(B) The maternity or paternity leave for which membership
service credit may be purchased shall terminate upon the
member’s return to covered employment and may not exceed
one (1) year for each natural birth or legal adoption; and
(C) A member may elect to purchase some or all of the
period of maternity or paternity leave for which the member
is eligible.
(20) A purchase of credit for Social Security covered employment
pursuant to section 169.655.11, RSMo, shall be allowed only in a
manner consistent with Title 26 of the United States Code and,
in addition, shall be governed by the following provisions:
(A) The member must have five (5) years of creditable service
and be vested with the retirement system prior to purchasing
credit for Social Security covered employment pursuant to
section 169.655.11, RSMo;
(B) The retirement system shall allow the purchase of no
more than five (5) years of credit for “nonqualified service” as
that term is defined in section 415 of Title 26 of the United States
Code if doing so would jeopardize the tax qualified status of the
retirement system pursuant to the Internal Revenue Code and
the retirement system determines that the provisions of section
415(n) of Title 26 of the United States Code apply to the purchase
of such member’s purchase;
(C) The member must supply evidence satisfactory to the
retirement system that the member is eligible to purchase
credit for Social Security covered employment pursuant to
section 169.655.11, RSMo;
(D) The member must submit to the retirement system
a detailed statement of the member’s employment history
created by the Social Security Administration in a format
satisfactory to the retirement system; and
(E) The retirement system shall determine the amount of
credit that may be purchased for Social Security covered
employment pursuant to section 169.655.11, RSMo, based on
the information provided pursuant to this section of this rule.
