Debited, if a participant terminates covered employment on or after January 1, 1990, but before December 30, 1999, and applies for a benefit under s. 40.25 (2), with an amount equal to the amount by which the core annuity division interest credited on or after January 1, 1990, but before December 30, 1999, to employee required contributions, exceeds the interest crediting at an annual rate of 3 percent on each prior year’s closing balance.

40.04(4)(a)3. 3. Debited by the amount available in any participant’s account for funding a benefit elected by the participant or the participant’s beneficiary.

40.04(5) (5) An employer accumulation reserve shall be maintained within the fund to which, without regard to the identity of the individual employer, shall be:

40.04(5)(a) (a) Credited all employer required contributions.

40.04(6) (6) An annuity reserve shall be maintained within the fund to which shall be transferred amounts equal to the present value as of the date of commencement of annuities granted under this chapter. The reserve shall be increased by investment earnings at the effective rate and shall be reduced by the aggregate amount of annuity payments and death benefits paid with respect to the annuities and by the present value at the date of termination of annuities terminated in accordance with s. 40.08 (3) or 40.63 (9) (c).

40.04(7) (7) The reserves established under subs. (4), (5), and (6) shall be divided both individually and for the purposes of sub. (3) between a core annuity division and a variable annuity division. All required and additional contributions shall be credited to the core annuity division except:

40.04(7)(a) (a) As otherwise elected by a participant prior to April 30, 1980, or on or after January 1, 2001. Any participant who was a participant prior to April 30, 1980, and whose accounts on January 1, 1982, include credits segregated for a variable annuity shall have his or her required and additional contributions made on or after January 1, 1982, credited to the variable annuity division in a manner consistent with the participant’s election prior to April 30, 1980, unless prior to January 1, 1982, the participant terminated such election under s. 40.85, 1979 stats. Any participant who elects or has elected to have any of his or her credits segregated for a variable annuity on or after January 1, 2001, shall have 50 percent of his or her required and additional contributions made on or after the date of election credited to the variable annuity division. The department shall by rule provide that any participant who elects or has elected variable participation prior to April 30, 1980, or on or after January 1, 2001, may elect to cancel that variable participation as to future contributions. The department’s rules shall permit a participant who elects or has elected to cancel variable participation as to future contributions, or an annuitant, to elect to transfer previous variable contribution accumulations to the core annuity division. A transfer of variable contribution accumulations under this paragraph shall result in the participant receiving the accrued gain or loss from the participant’s variable participation. A participant may specify that election to cancel participation in the variable annuity division is conditional. If the participant so specifies the election is effective on the first date on which it may take effect on which the participant:

40.04(7)(a)1. 1. Is an annuitant and the amount of the annuity the participant or member will receive if the election is made effective is greater than or equal to the amount of the annuity the participant or member would have received if the participant or member had not elected variable participation; or

40.04(7)(a)2. 2. Is not an annuitant and the accumulated amount which is to be transferred to the core annuity division is equal to or greater than the amount which would have accumulated if the segregated contributions had been originally credited to the core annuity division.

40.04(7)(b) (b) An election under par. (a) is irrevocable and continuing except a participant or member may make a conditional election unconditional by filing written notice with the department.

40.04(7)(c) (c) Any participant whose required contributions are segregated in any portion to provide for a variable annuity may direct that any part or all of subsequent additional contributions credited to the participant’s account be segregated to provide for a variable annuity and may at any time by filing a form prescribed by the department change the portion being segregated for any future additional contributions.

40.04(8) (8) A social security account shall be maintained within the fund to which shall be credited all moneys received from employee and employer OASDHI contributions including any penalties for late transmission of moneys or reports. All disbursements under subch. III shall be charged to this account.

40.04(9) (9) Separate group health, income continuation and life insurance accounts, and additional accounts for any other type of insurance provided under this chapter shall be maintained within the fund, to which shall be credited moneys received from operations of the respective group insurance plans for insurance premiums, as dividend or premium credits arising from the operation of the respective insurance plans and from investment income on any reserves established in the fund for the respective insurance plans. Premium payments to insurers, any insurance benefit to be paid directly by the fund and reimbursements of 3rd parties for benefits paid on behalf of an insurance plan shall be charged to the corresponding account established for that benefit plan. This subsection shall not be construed to prohibit the direct payment of premiums to insurers when appropriate administrative procedures have been established for direct payments.

40.04(9m) (9m) The department shall do all of the following:

40.04(9m)(a) (a) Maintain a separate account in the fund for each employee-funded reimbursement account plan authorized under subch. VIII.

40.04(9m)(b) (b) Credit to the appropriate accounts established under par. (a) money received from employees in connection with each employee-funded reimbursement account plan and income from investment of the reserves in the account.

40.04(9m)(c) (c) Charge to the appropriate accounts established under par. (a) payments made to reimburse employee-funded reimbursement account plan providers for payments made to employees under each employee-funded reimbursement account plan under subch. VIII.

40.04(10) (10) An accumulated sick leave conversion account shall be maintained within the fund, to which shall be credited all money received under s. 40.05 (4) (b), (bc), (bf), (bm), (br), and (bw) for health insurance premiums, as dividends or premium credits arising from the operation of health insurance plans and from investment income on any reserves established in the fund for health insurance purposes for retired employees and their surviving dependents, and for the payment of any employer share of OASDHI contributions for sick leave credits used to pay health insurance premiums for dependents who are not tax dependents under the Internal Revenue Code. Premium payments to health insurers authorized in s. 40.05 (4) (b), (bc), (bf), (bm), and (bw) shall be charged to this account. This subsection does not prohibit the direct payment of premiums to insurers when appropriate administrative procedures have been established for direct payments.

40.04(11) (11) A health insurance premium credit account shall be maintained within the fund, to which shall be credited all moneys received under s. 40.05 (4) (by) for the payment of health insurance premiums, as dividends or premium credits arising from the operation of health insurance plans and from investment income on any reserves established in the fund for health insurance purposes for retired employees and their surviving dependents, and for the payment of any employer share of OASDHI contributions for health insurance premium credits used to pay health insurance premiums for dependents who are not tax dependents under the Internal Revenue Code. Premium payments to health insurers authorized in subch. IX may only be charged to this account after all other health insurance premium credits under s. 40.05 (4) (b), (bc), (bf), (bm) and (bw) are exhausted. This subsection does not prohibit the direct payment of premiums to insurers when appropriate administrative procedures have been established for direct payments.

40.04(12) (12) The department shall establish and maintain a separate account in the fund to which shall be credited all moneys received from employees and employers in connection with health savings accounts established under s. 40.515.

40.05(1) (1) Employee retirement contributions. For Wisconsin retirement system purposes employee contributions on earnings for service credited as creditable service shall be subject to federal annual compensation limits and shall be made as follows:

40.05(1)(a) (a) Subject to par. (b):

40.05(1)(a)1. 1. For each participating employee not otherwise specified, a percentage of each payment of earnings equal to one-half of the total actuarially required contribution rate, as approved by the board under s. 40.03 (1) (e).

40.05(1)(a)2. 2. For each participating employee whose formula rate is determined under s. 40.23 (2m) (e) 2., a percentage of each payment of earnings equal to one-half of the total actuarially required contribution rate, as approved by the board under s. 40.03 (1) (e).

40.05(1)(a)4. 4. For each participating employee whose formula rate is determined under s. 40.23 (2m) (e) 4., the percentage of earnings paid by a participating employee under subd. 1.

40.05(1)(a)5. 5. Additional contributions may be made by any participant by deduction from earnings or otherwise or may be provided on behalf of any participant in any calendar year in which the participant has earnings, subject to any limitations imposed on contributions by the Internal Revenue Code, applicable regulations adopted under the Internal Revenue Code and rules of the department.

40.05(1)(a)6. 6. Under the rules promulgated under s. 40.03 (2) (r), additional contributions that are attributable to a death benefit paid under s. 40.73 may be made to the core annuity division by any participant by rollover contribution of a payment or distribution from a pension or annuity qualified under section 401 of the Internal Revenue Code, subject to any limitations imposed on contributions by the Internal Revenue Code, applicable regulations adopted under the Internal Revenue Code, and rules of the department.

40.05(1)(a)7. 7. For a county jailer covered under subd. 3., the percentage of earnings equal to the total actuarially required contribution rate, as approved by the board under s. 40.03 (1) (e), for a participating employee whose formula rate is determined under s. 40.23 (2m) (e) 3., less the contribution rate paid by the employer for a county jailer under sub. (2) (a). Contributions under this section for an employee who first becomes a participating employee as a county jailer in a county that did not classify county jailers as protective occupation participants on January 1, 2024, and is certified as a protective occupation participant on or after January 1, 2024, shall be made by a reduction in salary and, for tax purposes, shall be treated as employer contributions under section 414 (h) (2) of the Internal Revenue Code. Such a participating employee may not elect to have contributions required by sub. (2) (a) paid directly to the employee or make a cash or deferred election with respect to the contributions. Employees who are participating employees on January 1, 2024, and who are first certified as protective occupation participants in a county jailer position on or after January 1, 2024, in a county that did not classify county jailers as protective occupation participants on January 1, 2024, shall make the contribution under this section on a post-tax basis. For employees who are employed as county jailers in a county that classified county jailers as protective occupation participants on January 1, 2024, the county may at a subsequent date determine to categorize county jailers as general participating employees. In such instance, a county jailer who is employed by the county on the date the county determines to categorize county jailers as general participating employees may make a onetime irrevocable election to not be a protective occupation participant. A county jailer in such a county who opts to remain a protective occupation participant shall make the contribution under this section on a post-tax basis. A county jailer who is first hired as a county jailer by such a county after the date the county determines to categorize county jailers as general participating employees may make a onetime irrevocable election to not become a protective occupation participant. A county jailer who is first hired as a county jailer by such a county after the date the county determines to categorize county jailers as general participating employees and who opts to become a protective occupation participant shall make the contribution under this section on a pre-tax basis.

(a) shall be made by a reduction in salary and, for tax purposes, shall be considered employer contributions under section 414 (h) (2) of the Internal Revenue Code. A participating employee may not elect to have contributions required by par. (a) paid directly to the employee or make a cash or deferred election with respect to the contributions.

40.05(1)(b)1a. 1a. Contributions under par. (a) 7. that are made by county jailers who are first certified as protective occupation participants on or after January 1, 2024, and who are employed in a county that did not classify county jailers as protective occupation participants on January 1, 2024, shall be treated as employee contributions.

40.05(1)(b)2. 2.

40.05(1)(b)2.a. a. A municipal employer shall pay, on behalf of a nonrepresented law enforcement or fire fighting managerial employee or a nonrepresented managerial employee described in s. 111.70 (1) (mm) 2., who was initially employed by the municipal employer before July 1, 2011, the same contributions required by par. (a) that are paid by the municipal employer for represented law enforcement or fire fighting personnel or personnel described in s. 111.70 (1) (mm) 2. who were initially employed by the municipal employer before July 1, 2011.

40.05(1)(b)2.b. b. An employer shall pay, on behalf of a nonrepresented managerial employee in a position described under s. 40.02 (48) (am) 7. or 8., who was initially employed by the state before July 1, 2011, in a position described under s. 40.02 (48) (am) 7. or 8. the same contributions required by par.

40.05(1)(b)2.c. c. A municipal employer shall pay, on behalf of a represented law enforcement or fire fighting employee or employee described in s. 111.70 (1) (mm) 2., who was initially employed by the municipal employer before July 1, 2011, and who on or after July 1, 2011, became employed in a nonrepresented law enforcement or fire fighting managerial position or nonrepresented managerial position described in s. 111.70 (1) (mm) 2. with the same municipal employer, or a successor municipal employer in the event of a combined department that is created on or after July 1, 2011, the same contributions required by par. (a) that are paid by the employer for represented law enforcement or fire fighting personnel or personnel described in s. 111.70 (1) (mm) 2. who were initially employed by a municipal employer before July 1, 2011.

40.05(2)(a) (a) Each participating employer shall make contributions for current service determined as a percentage of the earnings of each participating employee, determined as though all employees of all participating employers were employees of a single employer, but with a separate percentage rate determined for the employee occupational categories specified under s. 40.23 (2m). A separate percentage shall also be determined for subcategories within each category determined by the department to be necessary for equity among employers.

40.05(2)(am) (am) The percentage of earnings under par. (a) shall be determined on the basis of the information available at the time the determinations are made and on the assumptions the actuary recommends and the board approves by dividing the amount determined by subtracting from the then present value of all future benefits to be paid or purchased from the employer accumulation reserve on behalf of the then participants the amount then credited to the reserve for the benefit of the members and the present value of future unfunded prior service liability contributions of the employers under par. (b) by the present value of the prospective future compensation of all participants.

40.05(2)(ap) (ap) The contributions under par. (a) that are required to be paid by a participating employer for a county jailer whose formula rate is determined under s. 40.23 (2m) (e) 3. shall be a percentage of earnings equal to one-half of the total actuarially required contribution rate, as approved by the board under s. 40.03 (1) (e), for an employee whose formula rate is determined under s. 40.23 (2m) (e) 1. This paragraph applies only to contributions paid for a county jailer who becomes a protective occupation participant on or after January 1, 2024, and is one of the following:

40.05(2)(ap)2. 2. Employed in a county that classified county jailers as protective occupation participants on January 1, 2024, and the county subsequently determines to not classify county jailers as protective occupation participants and instead classify county jailers as general participating employees.

40.05(2)(ar) (ar)

40.05(2)(ar)1. 1. Except as provided in subd. 2., participating employers of employees subject to s. 40.65 shall contribute an additional percentage or percentages of those employees’ earnings based on the experience rates determined to be appropriate by the board with the advice of the actuary.

40.05(2)(ar)2. 2. County jailers who are first hired as protective occupation participants on or after January 1, 2024, in a county that did not classify county jailers as protective occupation participants on January 1, 2024, may make the contribution under subd. 1. on a pre-tax basis, in lieu of their employers making the contribution. County jailers who are first certified as protective occupation participants on or after January 1, 2024, in a county that did not classify county jailers as protective occupation participants on January 1, 2024, shall make the contribution under subd. 1. on a post-tax basis, in lieu of their employers making the contribution. For employees who are employed as county jailers in a county that classified county jailers as protective occupation participants on January 1, 2024, the county may at a subsequent date determine to categorize county jailers as general participating employees. In such instance, a county jailer who is employed by the county on the date the county determines to categorize county jailers as general participating employees may make a onetime irrevocable election to not be a protective occupation participant. A county jailer in such a county who opts to remain a protective occupation participant shall make the contribution under subd. 1. on a post-tax basis. A county jailer who is first hired as a county jailer by such a county after the date the county determines to categorize county jailers as general participating employees may make a onetime irrevocable election to not become a protective occupation participant.

(bm) may not be less than the dollar amount determined to be necessary in the first calendar year of the amortization schedule established by par. (b).

40.05(2)(bt) (bt) The department may reallocate prior service liability from one employer to another and adjust as necessary the contribution rates established under par. (b) to reflect transfers of responsibilities and employees among different employers.

40.05(2)(bu) (bu) The employer contribution rate determined under par. (b) for each employer shall be adjusted, if necessary, to reflect the added prior service liability of paying additional joint and survivor death benefits to beneficiaries of participating employees as a result of 1997 Wisconsin Act 58 and that rate shall be sufficient to amortize the unfunded prior service liability of the employers over the remainder of the 40-year amortization period under s. 40.05 (2) (b), 2005 stats.

(b) for the department of administration shall be adjusted to reflect the cost of granting creditable service under s. 40.02 (17) (gm) and that rate shall be sufficient to amortize the unfunded prior service liability of the department of administration over the remainder of the 40-year amortization period under s. 40.05 (2) (b), 2005 stats.

40.05(2)(c) (c) The percentage rates determined under this subsection shall become effective as of the beginning of the calendar year to which they are applicable and shall remain in effect during the calendar year, except that the secretary, upon the written certification of the actuary, may change any percentage determined under par. (b) during any calendar year for the purpose of reflecting any reduced obligation which results from any payment of advance contributions.

40.05(2)(cm) (cm) The department may adjust the unfunded prior service liability balance of the Wisconsin retirement system under par. (b) and of each employer that makes contributions under par. (b) to reflect any changes in the assumed rate and the assumption for across-the-board salary increases specified in s. 40.02 (7) and any other factor specified by the actuary if the actuary recommends and the board approves the changes or if otherwise provided by law.

40.05(2)(d) (d) The amount of each employer’s monthly contribution shall be the sum of the amounts determined by applying the proper percentage rates as determined in accordance with pars. (a) and (b) to the total of all earnings paid to participating employees on each payday.

40.05(2)(f) (f) Whenever the existence of any participating employer is terminated because of consolidation or for any other reason, the employer who thereafter has responsibility for the governmental functions of the previous employer shall be liable for all contributions payable by the previous employer in the following manner:

40.05(2)(f)1. 1. If the territory of the previous employer is attached to 2 or more employers, the total liability of the previous employer shall be allocated to the new employers in proportion to the equalized valuation of each area so attached.

40.05(2)(f)2. 2. Whenever the existence of any participating employer, who was an instrumentality of 2 or more employers, is terminated for any reason and there is no territory to be divided, the liability for contributions of the previous employer shall be divided between the sponsoring employers in the same proportion as the net assets of the terminating employer are divided.

40.05(2)(f)3. 3. If the department determines that it is not feasible to allocate the liability as provided in subd. 1. or 2., then the liability shall be allocated in proportion to the equalized valuation of the remaining employers.

40.05(2)(f)4. 4. The amount of the allocations to the respective employers shall be certified by the department to each employer.

40.05(2)(f)5. 5. If the employer to whom such an allocation is made is or becomes a participating employer the allocations so certified shall be added to the liability otherwise determined for the employer and the amortization schedule provided for under par. (b) adjusted so that the required annual amount shall approximate the sum of the annual amounts otherwise required.

40.05(2)(f)6. 6. If the employer who becomes responsible for any part of the liability of the previous employer is not a participating employer the contributions required to liquidate the allocated liability shall be made by the successor employer in equal quarterly payments sufficient to liquidate the allocated liability over the remainder of the amortization period.

40.05(2)(f)7. 7. If an allocation based on equalized valuation is required by this paragraph, the equalized valuations used shall be the valuation determined for the calendar year immediately preceding the calendar year in which the allocation is required to be made by this paragraph.

40.05(2)(f)8. 8. If it is not possible to apply the procedures under this paragraph, the terminating employer and any successor employer shall immediately pay the full outstanding prior service liability balance unless an agreement for a different procedure is approved by the department.

The amount payable shall be paid to the department in 3 equal annual payments, plus interest at the effective rate unless the employer pays the full amount due. Each annual payment is due and shall be included with the first payment made under s. 40.06 (1) in each fiscal year after the annuity effective date. The amount so paid shall be credited as employer required contributions.
