Iowa MFPRSI Retirement: Options, Refund, DROP, Survivors

Updated October 16, 2026. Quick answer: The Municipal Fire and Police Retirement System of Iowa (MFPRSI) pays a basic benefit of 66% of average final compensation to a member with 22 years of service and age 55, plus 2% for each year over 22 up to 30. A retiree picks the basic benefit, which pays a spouse 50%, or one of six optional forms, including joint 75% and 100% survivor annuities. Leaving before 55 means a refund of contributions with interest, which waives other benefits, or a vested pension after 4 years of service. DROP runs three to five years and pays out as a lump sum or a rollover. Iowa Code chapter 411 adds that a DROP decision is irrevocable, that an option election becomes irrevocable once the first benefit is accepted, and that a married member needs the spouse’s written consent to an option.

What this page covers and what it does not

This page works from three MFPRSI documents: the Member Benefit Handbook (dated 07/2025 on its pages), the Actuarial Valuation Report as of July 1, 2026, and the Annual Report for Fiscal Year 2025. MFPRSI covers police officers and firefighters of participating Iowa cities, and the Handbook describes one benefit structure for all members rather than separate tiers, but Iowa Code 411.6(2) ties the percentage to the date a member terminated or retired. For retirement on or after July 1, 2000: “Upon retirement from service on or after July 1, 2000, a member shall receive a service retirement allowance which shall consist of a pension which equals sixty-six percent of the member’s average final compensation.” A member who terminated earlier falls under the lower percentages in 411.6(2)(a), (b) and (c), and the extra credit for years over 22 also changes with the termination date in 411.6(2)(e). The Handbook calls itself “a general summary of the benefit provisions”, and notes that “Revisions can only be instituted by the Iowa General Assembly”. The valuation gives the size of the group: “The number of active members increased from 4,254 in 2025 to 4,296 in 2026.” Another Iowa system, for most public employees, is covered at Iowa IPERS retirement decisions.

When a service pension can start and how it is figured

The Handbook’s eligibility rule: “You must be age 55 or older with at least 22 years of service in order to qualify for a service retirement benefit.” The formula: “If you have worked exactly 22 years, the service retirement benefit is equal to 66% of your average final compensation.” Above 22 years, “there is an additional two percent credit for each year worked over 22 years but not exceeding 30 years”. The valuation states the ceiling: “The maximum benefit is 82.0% of Average Final Compensation.” The base is a three-year average: “Your average final compensation is the average of your earnable compensation using your highest three years of compensation.” Earnable compensation excludes items such as overtime, uniform allowances and severance pay, and the Handbook’s full list should be read before estimating. Iowa Code 411.1(10) sets the statutory exclusions: “However, the term “earnable compensation” or “compensation earnable” shall not include amounts received for overtime compensation, meal or travel expenses, uniform allowances, fringe benefits, severance pay, or any amount received upon termination or retirement in payment for accumulated sick leave or vacation.” “Contributions made by a member from the member’s earnable compensation to a plan of deferred compensation shall be included in earnable compensation.”

A computed example from an assumed $96,000 average final compensation and an assumed 25 years of service, not an MFPRSI figure: the multiplier is 66% plus 2% for each of the 3 years over 22, which is 72%. Applied to $96,000 that is $69,120 a year, or a computed $5,760 a month, before any option reduction.

The election at retirement: the basic benefit or six optional forms

A member retiring on a service pension chooses how the pension is paid. The Handbook says the member may select the basic benefit or one of six optional forms, and that “the spousal benefit provided under the basic benefit plan is replaced by the option selected”. “The six options are calculated using actuarial tables which were developed to consider your age at retirement, your spouse’s age, the age of your designated beneficiary, and the assumed life expectancy of both you and your beneficiary.” The Handbook adds: “Survivor benefits will be paid according to the benefit payment option you select upon the member’s death after retirement.”

On the pop-up forms the Handbook says: “If your beneficiary predeceases you, then your retirement benefit will increase to the amount of the basic benefit service retirement and no survivor benefit is payable following your passing.” The Handbook states of its sample that “These calculations are for informational purposes only.” Measured against the sample’s basic benefit of $5,550, the joint 75% form pays 96%, the joint 100% form pays 92%, the form with the designated lump sum pays 55% and the straight-life annuity pays 109% (computed here from the Handbook’s printed amounts, not stated by MFPRSI). Those ratios depend on the sample’s ages and lump sum and are not a schedule of reductions. Iowa Code 411.6A(3) states the rule behind them: “The optional forms of payment determined by the board of trustees under this section, shall be the actuarial equivalent of the amount of retirement benefits payable to the member and the member’s spouse pursuant to section 411.6, subsections 2 and 11.” “Election of an optional form adopted by the board of trustees shall not affect the benefits, if any, payable to the member’s child or children pursuant to section 411.6, subsection 11.”

The comparison between a life-only pension and one with a survivor is covered at single-life versus joint-and-survivor pension.

Who can elect a form, and the timing the documents give

The Handbook says “Optional forms of benefits (as described in the service retirement section of this manual) are available for terminated vested members”. For accidental or ordinary disability retirement, it says optional forms are not available.

On timing, the checklist reads: “Contact us three to six months prior to your retirement date to obtain a service retirement application and a benefit estimate.” “Submit your service retirement application and certificates to us no more than 90 days prior to your retirement date.” If an optional form is chosen, “we require a marriage certificate and/or your designated beneficiary’s birth certificate with your application”. Iowa Code 411.6(1)(a) sets the statutory window: “Any member in service may retire upon written application to the system, setting forth at what time, not less than thirty nor more than ninety days subsequent to the execution and filing of the application, the member desires to be retired. However, the member at the time specified for retirement shall have attained the age of fifty-five and shall have served twenty-two years or more, and notwithstanding that, during the period of notification, the member may have separated from the service.”

Iowa Code 411.6A(2) settles what the Handbook leaves open. Timing: “Prior to the member’s retirement and as a part of the application for a service retirement allowance, the member shall elect, in writing, either the benefits provided under section 411.6, subsections 2 and 11, or one of the optional forms adopted by the board of trustees.” Spouse: “If the member is married at the time of application and the member elects an optional form, the member’s spouse must consent in writing to the optional form selected and to the receipt of payments to a designated recipient, if applicable.” Change: “Upon acceptance by a member of an initial retirement benefit paid in accordance with the election under this section, the election of the member is irrevocable.” The general rules on waiving a spouse’s survivor share are at spousal consent to waive a joint and survivor annuity.

Survivor benefits: after retirement, before retirement and for children

For a retired member who took the basic benefit, the Handbook’s death after retirement rule says: “Your surviving spouse is entitled to an amount equal to 50% of your gross benefit, but not less than 20% of the average earnable compensation of the active membership of the retirement system, as reported by the actuary.” For a retiree who chose an option, “if you retired on a service retirement benefit and selected an optional form of benefit instead of the basic benefit plan, the eligibility and benefits are paid in accordance with the option chosen”. The Handbook adds: “This benefit is not affected by remarriage of your surviving spouse.” Iowa Code 411.6(11)(a) sets the base survivor pension: “To the spouse, equal to one-half the amount received by the deceased beneficiary, but in no instance less than twenty percent of the average monthly earnable compensation paid to an active member of the system, as determined by the actuary, and in addition a monthly pension equal to the monthly pension payable under subsection 9 of this section for each child;”

Before retirement the benefit differs. The Handbook applies its ordinary death benefit to an active member with at least one year of service, or a terminated vested member, who dies from causes not sustained in the line of duty (the valuation lists any length of service for a member in service and 4 years for a member not in service). The Handbook says “Your beneficiary is entitled to the greater of a lump sum equal to 50% of your earnable compensation during your last year of service or a refund of contributions”. For the death of an active member from a traumatic injury incurred in the line of duty, “Your surviving spouse or dependents are entitled to a single lump-sum payment of $100,000”. The Handbook also describes monthly pensions for children. Iowa Code 411.6(8)(b) adds a choice the lump-sum description leaves out: in lieu of the lump sum, a qualifying beneficiary may elect “a monthly pension equal to one-twelfth of forty percent of the average final compensation of the member, but not less than twenty percent of the average monthly earnable compensation paid to an active member of the system, as reported by the actuary.” Only the member’s spouse, or the member’s children when there is no spouse, may select it (411.6(8)(c)). For a member in service at death: “For a member in service at the time of death, the pension shall be paid commencing with the member’s death.” For a member not in service at death, 411.6(8)(b) reduces the pension in the vested-member proportion and starts it when the member would have reached 55, or sooner while there is a child.

Iowa Code 411.6(9) separately provides an accidental death pension when a member in service dies as the result of an injury or disease incurred in or aggravated by the performance of duty: “If the member’s designated beneficiary is the member’s spouse, child, or parent, an accidental death benefit pension equal to one-half of the average final compensation of the member shall be paid as follows:” It goes to whichever of the spouse, the children or a dependent parent the member designated; with no designation, to the spouse, then the children, then a dependent parent (411.6(9)(b)). Each child also receives “a monthly pension equal to six percent of the average monthly earnable compensation paid to an active member of the system, as reported by the actuary.” The $100,000 line-of-duty payment in 411.6(15) is not payable in every case; one listed bar is that “The death was caused by the intentional misconduct of the member or by the member’s intent to cause the member’s own death.”

Because MFPRSI pays the beneficiary on file, the Handbook warns that “it is your responsibility to update beneficiary designations as you experience major life changes”. Iowa Code 411.6(14) makes two points binding: “If the member is married at the time a designation is signed, a designation of a beneficiary other than the member’s spouse shall not be valid unless the member’s spouse consents in writing to the designation.” “A designation filed with the system shall be deemed revoked if, subsequent to the designation, a new designation is filed with the system, the member marries, or the member divorces the individual who was the member’s named beneficiary.” For how a survivor pension from a government plan can interact with other benefits, see survivor benefit with a government pension.

DROP: the three-to-five-year path and its lump-sum payout

The Deferred Retirement Option Plan (DROP) is for a member who is already eligible to retire and keeps working. The Handbook’s rule: “If you are an active member, at least 55 years of age, and have 22 or more years of service you are eligible to participate in DROP.” “DROP offers participation periods of three, four, and five years.” The Annual Report describes the commitment: “By electing to participate in DROP the member is signing a contract indicating the member will retire at the end of the selected DROP period.” Iowa Code 411.6C(2)(a) adds: “A decision by an eligible member to participate in the plan is irrevocable.” “Participation in the plan by an eligible member does not guarantee continued employment.” “Contributions required from members and participating cities shall continue based on the earnable compensation of an eligible member participating in the plan.”

How the account is built: the valuation says the credited portion is a minimum percentage of 52% of the Chapter 411 benefit plus an adjustment percentage of 2% for each month of delay, up to 24 months. The Handbook says: “For each month you delay participation an additional 2% will be added as an adjustment percentage.” The Handbook’s worked case: “if you wait 24 months to enroll in DROP, your overall DROP formula will be 52% plus 48% (2% x 24 months) equals 100%”. “An amount equal to 75% of your DROP benefit will accumulate to your DROP account for each month of participation in the plan.” The Handbook says an additional 25% of the accumulated DROP benefit accrues if the member finishes the selected period, leaves it because of a disability benefit, or dies before the selected termination date. The statute frames the same 25% as a penalty, not an extra accrual. Iowa Code 411.6C(1)(b) defines the monthly credit as “an amount credited to the participant’s account each applicable month equal to the member’s applicable percentage multiplied by the member’s participant retirement amount.” Iowa Code 411.6C(2)(c): “If an eligible member terminates participation in the plan prior to the date selected by the member upon commencing membership in the plan and the termination is not due to the death or disability of the member under this chapter, then the system shall assess a twenty-five percent penalty on the amount credited to the member’s participant account prior to distributing the amount to the member.”

A computed example from an assumed $5,000 Chapter 411 benefit, an assumed 12 months of delay and an assumed 36 month DROP period, not MFPRSI figures: the credited percentage is 52% plus 2% for each of 12 months, which is 76%, so $3,800 a month is credited. At the 75% monthly accrual that is $2,850 a month, or $102,600 over 36 months. Read the statutory way, the full credit is $3,800 a month for 36 months, which is $136,800; the 25% penalty for leaving before the selected date is $34,200, which leaves $102,600, the same as the 75% figure above (computed here from the assumed figures, not stated by MFPRSI).

On investment returns the Handbook says: “Earnings, capital gains, and loss on investments will be credited to the retirement system’s assets and not to your DROP account.” Iowa Code 411.6C(2)(a) states the rule: “The amounts credited shall be invested by the system in risk-free assets of a short-term nature and interest and earnings shall not be credited to the member’s participant account but shall remain with the fire and police retirement fund established in section 411.8.”

Payout: “Your DROP distribution can be paid either by a lump-sum distribution or as a rollover to an eligible plan.” The Handbook adds that “you will not be paid your DROP distribution until the month following your retirement in order for your break in service to be verified”. A member who withdraws early or works past the termination date does not earn the 25% accrual; for death or disability, “either you or your beneficiary will receive the entire amount from your DROP account with no reduction”. Money not rolled over falls under the IRS rules below; see 20% withholding on a pension lump sum. Iowa Code 411.6C(2)(b) says what happens at the end: “Upon termination of an eligible member’s participation in the plan, the eligible member shall be deemed to be retired under the system as of that date for purposes of the system and shall begin receiving a retirement allowance equal to the member’s participant retirement amount or such optional retirement benefits, based upon that amount, pursuant to section 411.6A.”

Leaving before 55: a refund of contributions or a vested pension

A member who leaves covered service before 55 has two paths. The first is a refund: “If you terminate active service other than by death or disability, you may withdraw your contributions from your date of hire with interest calculated for the period of membership.” The price of that choice: “If you do withdraw contributions, you waive all claims for other benefits for the period of membership for which the withdrawal is made.” The Handbook adds a rollover route: “You have the option to rollover the taxable portion of your refund directly to another qualified retirement plan or to an Individual Retirement Account (IRA).” “Such rollovers must be approved in advance by MFPRSI.” The Annual Report says the contributions being withdrawn are credited with an annualized simple interest rate determined by the Board, currently set at 5 percent; the member contribution rate itself is currently 9.675% of earnable compensation. Iowa Code 411.8(1)(f) sets that rate from July 1, 2025 and caps increases that pay for later statutory changes at 11.475%. Iowa Code 411.23(1) says the board of trustees determines the interest rate, and adds: “If the member is married at the time of the application for withdrawal, the application is subject to the consent of the member’s spouse unless the amount to be withdrawn does not exceed the amount that may be withdrawn without consent as established by section 401(a) of the federal Internal Revenue Code.”

The second path is the terminated vested pension. “If you have at least four years of service upon termination of membership and are not yet age 55, or reach age 55 while an active member, you are eligible to receive a terminated vested retirement benefit.” The pension is a fraction of the service pension: “The fraction is 4/22 for four years of service plus 1/22 for each additional year of service up to a total of 22 years.” “Terminated vested benefits begin when you reach age 55.” “This pension is not eligible for the annual escalator.” The Handbook also says “Optional forms of benefits (as described in the service retirement section of this manual) are available for terminated vested members”. Iowa Code 411.6(1)(b) states the fraction this way: a vested member “shall receive a service retirement allowance equal to one twenty-seconds of the retirement allowance the member would receive based on twenty-two years of service, multiplied by the number of years of service credited to the member.” The same paragraph pays a vested member with four or more years at retirement age, and a vested member with less than four years on application, and Iowa Code 411.1(25) counts as vested a member with four years of service or one who reaches 55 while performing membership service.

A computed example from an assumed $96,000 average final compensation at termination and an assumed 10 years of service, not MFPRSI figures: the fraction is 4/22 plus 1/22 for each of 6 more years, which is 10/22. Applied to the 66% multiplier that is $28,800 a year, or a computed $2,400 a month, starting at 55 and without the annual escalator.

For the general question of a refund versus leaving the money in a plan, see pension refund versus leaving it. A refund can be restored by service purchase, as the next section shows. Iowa Code 411.23(3) also provides an automatic refund: “Commencing July 1, 2006, a member’s contributions shall be refunded to the member by the system if the following conditions are met:” the member was a member for less than four years, terminated service four or more years before the refund, and the amount does not exceed $5,000 (or the other amount set under Internal Revenue Code section 401(a)). Without the member’s consent it goes by direct rollover to an individual retirement plan the system designates, unless the member elects otherwise.

Buying back refunded service or military service

A member who took a refund and later returns to covered work can rebuild the service. The Handbook: “If you are an active member with five or more years of service who previously received a refund of contributions, you may restore the period of service by paying the actuarial cost to restore the credit.” “The maximum number of years allowed to purchase for prior service is five years.” For veterans, the Handbook allows an active member with at least five years of service to buy military credit: “you may purchase up to five years of service credit for the service time you were in the military”. A general tool for comparing such costs is the pension buyback calculator. Iowa Code 411.23(2) has a narrower repayment route for a member recalled after an indefinite layoff who had withdrawn contributions: “However, the member must make the contributions within two years of the date of the member’s return to service.” The military purchase in 411.10(1) leaves out service the system must already recognize under federal law (USERRA).

The annual escalator (cost-of-living increase)

MFPRSI’s cost-of-living adjustment is called the annual escalator. “Your eligible benefit will be adjusted on an annual basis in July.” The formula includes “Your previous monthly gross benefit multiplied by 1.5%” plus a dollar step based on years retired: $15 for fewer than 5 years, $20 for 5 to under 10, $25 for 10 to under 15, $30 for 15 to under 20 and $35 for 20 or more. “All benefits except for terminated vested benefits are eligible for the annual escalator.” “Your benefit will not be escalated during your DROP participation period.” Iowa Code 411.6A(4) extends it to the optional forms: “Optional benefits shall be adjusted annually in a manner consistent with that provided in section 411.6, subsection 12.”

A computed example from an assumed $5,000 monthly benefit and a retiree with fewer than 5 years of retirement, not MFPRSI figures: 1.5% of $5,000 is $75, plus the $15 step, so the benefit becomes $5,090 a month after one July adjustment.

Going back to work after retiring

Iowa Code 411.3(3)(a) defines reemployment as being employed as a police officer or fire fighter by a participating city after the person has begun receiving a service retirement allowance. Iowa Code 411.3(3)(b): “If a person is reemployed, the person shall not become an active member of the system upon reemployment, and the person so reemployed and the participating city shall not make contributions to the system based upon the person’s compensation for reemployment.” “A person who is so reemployed shall not be eligible to receive a service retirement allowance for the period of reemployment.” “The service retirement allowance shall be reinstated upon termination of the reemployment, but the service retirement allowance shall not be recalculated based upon the person’s reemployment.”

What the IRS adds on tax

A refund or lump sum from a public pension is a distribution, so the IRS rules apply on top of MFPRSI’s own. On withholding, the IRS says that a taxable eligible rollover distribution paid to you “is subject to mandatory income tax withholding (generally at a rate of 20%), even if you intend to roll it over later”, and that if you roll it over yourself “you’ll have to add funds from other sources equal to the amount withheld”. The Handbook says refund rollovers must be approved in advance by MFPRSI, and that a DROP distribution can be paid as a rollover to an eligible plan, which is how the mandatory withholding on the rolled-over part is avoided. The rollover clock, if the money is paid to you: “you have 60 days from the date you receive it to roll it over to another eligible retirement plan”.

On early distributions the IRS says “the law imposes a 10% additional tax on certain early distributions from certain retirement plans”. Its list of exceptions includes “Distributions made to you after you separated from service with your employer after attainment of age 55” and distributions made to a qualified public safety employee from a governmental plan, provided the employee separated from service during or after the year in which they attained age 50 or 25 years of service under the plan, whichever is earlier. Whether an exception fits a particular refund depends on your own plan and facts, so confirm it with a tax preparer before you take one.

Where the sources disagree

Who can take a refund. The Handbook allows a refund to a member who terminates other than by death or disability, and the valuation says “members who terminate service, other than by death or disability, can elect to withdraw their accumulated contributions with interest”. The Annual Report’s retirement summary is narrower: “Members with less than four years of service are entitled to a refund of their contribution only, with interest for the period of employment.” The Annual Report’s own Description of Benefit Plan also says that, since July 1, 1990, members who terminate service other than by death or disability may withdraw their contributions, which matches the Handbook and the valuation. Only the summary line about members with less than four years is narrower. Iowa Code 411.23(1) sets the refund election without a service minimum: any active member who terminates service other than by death or disability may withdraw the member’s contributions with interest. The four-year figure in that section belongs to the automatic refund of a small account (411.23(3)); in 411.1(25) and 411.6(1)(b) it governs vesting and when a vested pension starts.

What this page could not settle

• Iowa Code 411.6A(2) answers both: the election becomes irrevocable once the first benefit is accepted, and a married member’s spouse must consent in writing (quoted above). Whether the board’s administrative rules allow a correction before the first payment was not checked.
• The documents read contain no table of reduction factors for the options; the only amounts are the Handbook’s one sample (member age 59, beneficiary age 58). Iowa Code 411.6A(3) requires each option to be the actuarial equivalent of the basic benefit but does not print the factors.
• The Handbook gives no dollar cost for buying back refunded or military service, only that the actuarial cost is paid. The refund interest rate is stated in the Annual Report as an annualized simple rate set by the Board, currently 5 percent.
• Iowa Code 411.6C(2)(b), quoted above, says a DROP participant who exits begins an allowance or an optional form based on the participant retirement amount; section 411.6C itself does not say when the option election is filed, and how the 411.6A(2) rule (before retirement, as part of the application) applies to a DROP participant was not checked.
• Iowa Code chapter 411 (Code 2026 edition, printed December 9, 2025) was read on October 24, 2026 for the sections quoted above. Disability retirement, the board’s administrative rules, the valuation’s limited one- and two-year DROP window after April 1, 2007, and any amendment after that edition were not examined in depth.

Common mistakes

• Treating the basic benefit as a single-life pension when the Handbook says the spouse receives 50% under it, and not comparing it with the joint 75% and 100% forms.
• Withdrawing contributions without weighing that the Handbook says a withdrawal waives all claims for other benefits for that period of membership.
• Entering DROP expecting investment earnings; the Handbook says earnings are credited to the retirement system’s assets and not to the member’s account.
• Taking a taxable refund instead of a direct rollover and receiving 20% less in cash up front.
• Treating an option election or a DROP decision as reversible; Iowa Code 411.6A(2) makes the election irrevocable once the first benefit is accepted, and 411.6C(2)(a) makes the DROP decision irrevocable.
• Naming a beneficiary other than a spouse without the spouse’s written consent, which Iowa Code 411.6(14) makes invalid, or leaving an old designation in place after marrying, or after divorcing the person it names, either of which revokes it.
