PERSI Retirement Rules: How to Plan for a Secure and Comfortable Retirement

Admin • January 5, 2024

The Public Employee Retirement System of Idaho (PERSI) is a retirement plan for public employees of Idaho, made up of members from over 850 employer organizations across the state. The $22 billion plan offers retirement, disability, and death benefit programs to over 177,000 members. In 2022, over $1 billion in benefits were paid to PERSI retirees living in Idaho, with an average monthly benefit of $1,800. 

Whether you’re a new public employee just entering PERSI, or you’re nearing retirement and thinking about your future, understanding PERSI’s retirement rules can help you in your retirement planning. Having a comprehensive plan that includes your PERSI benefits can lay the foundation for a secure and comfortable retirement in your golden years. 

Understanding PERSI Basics

PERSI was founded in 1963 as a defined benefit retirement plan to offer a measure of retirement security for Idaho’s public employees. Through the plan, retirees receive a fixed monthly pension based on factors including years of service and salary. 

During its first 35 years, PERSI’s plan was a traditional defined benefit plan, now known as the PERSI Base Plan ; in 2001, PERSI added a defined contribution plan, called the PERSI Choice 401(k) Plan , to supplement the Base Plan. 

  • Base Plan : Enrollment in the defined benefit Base Plan is automatic, and once vested, you’ll receive a lifetime benefit at retirement. Both you and your employer make contributions to the Base Plan, which are invested and grow over time. Your contributions go into your personal account, while employer contributions are pooled in a trust fund to cover future benefits for all members. 

For 2023, as a general member, you contribute 6.71% of your annual salary to the Base Plan, and your employer contributes 11.18%. This percentage varies if you are a public safety member or a school employee member, and it will increase for all members in 2024. Retiring as a vested member means you’ll receive a fixed monthly payment for the rest of your life.

  • Choice 401(k) Plan : Participation in the defined contribution Choice 401(k) Plan is voluntary, unlike the Base Plan. The Choice 401(k) Plan allows you to contribute a portion of your salary, pre-tax, via payroll deductions. You can direct your investments among several investment options. The amount available in your Choice 401(k) at retirement is dependent on your contributions and the performance of your investments.

The combination of these two plans from PERSI offers an optimal blend – the security of the Base Plan, and the opportunity for self-directed investments and voluntary contributions in the Choice 401(k) Plan.

PERSI Eligibility and Retirement Rules

Understanding how to join PERSI and what it means for your retirement is paramount for utilizing this helpful benefit and resource. 

Joining PERSI

When you work in an eligible position for one of over 850 PERSI employers, you become a PERSI member. As an eligible employee, you accrue service credit for each month you work; the credited service is used to calculate your PERSI benefit at retirement. You’ll earn one month of service for each calendar month worked, with at least 20 hours worked during a week. You won’t earn additional service credit by working overtime.

Once you’ve earned 60 months of service credit, you’ll be considered vested and receive a lifetime benefit at retirement. The five-month vesting period doesn’t need to be with the same PERSI employer – you can change public service jobs without impacting your PERSI membership.

Planning for Retirement

To receive your full PERSI retirement benefits, you must reach your service retirement age; or, you must meet the minimum age requirement when you retire, have at least 60 months of credited service, and you also must meet the Rule of 80/90 . These requirements differ if you are a general member, or public safety member – police officer or firefighter.

The Rule of 80/90 = your age + your years of service = 80/90 (or more)

For general members, you must be at least 55 years old and meet the Rule of 90. For police officers or firefighters, you must be 50 years old and meet the Rule of 80. For members with mixed service, your requirements depend on your ratio of general and police-firefighter service –  you’ll have to be between 50-55 years old and meet a Rule of 80 or 90, with both depending on your ratio.

If you retire before reaching your service retirement age (65 years old for general members, 60 years old for police and firefighters), or before reaching the Rule of 80/90, your retirement benefit will be reduced.

If you decide to work beyond your service retirement age or the Rule of 80/90, your retirement benefit will continue to increase.

Calculating Your PERSI Retirement Benefits

Determining the amount of your PERSI retirement benefits and how much income you’ll receive can help you better plan for retirement. PERSI benefits are calculated using a straightforward formula involving your average monthly salary during a Base Period (currently 42 months), a multiplier of 2% for general members or 2.3% for police officers and firefighters, and your months of service.

Average Monthly Salary during Base Period  x Multiplier x Months of Service

For example, if you’re a general member, your average monthly salary is $3,000, and you have 360 months of service:

$3000 x 2% x 360 months = $21,600 

÷ 12 months = 

Monthly benefit of $1,800

The value of your PERSI benefits typically far exceeds your contributions – within the first 3-5 years of retirement, most PERSI members have received a return greater than the money they contributed while working. And you’ll continue to receive your benefits payment for the rest of your life. PERSI also considers cost-of-living adjustments (COLAs) to Base Plan benefit payments annually. Your PERSI benefits are a guaranteed, long-term source of retirement income – something very difficult to find in another investment.

Planning for Retirement with PERSI

There are several retirement distribution options available for PERSI members to choose from. The Regular Retirement option provides the largest benefit, with full payment throughout your life, but it has no Contingent Annuitant (CA) protection for your spouse or dependents. PERSI offers two CA Allowance retirement distribution options with either 100% or 50% CA allowances, as well as a Social Security Adjustment option and two options that are a CA/Social Security blend.

If you’re planning on retiring in the next few years, or even if you’re years away from retirement, knowing how the PERSI retirement process works can help make it more efficient and seamless. PERSI provides a helpful retirement checklist to follow throughout your career as a guide.

Comprehensive Retirement Planning

A comprehensive retirement plan that includes income and investments beyond your PERSI Base Plan and Choice 401(k) Plan will offer you more opportunities to save for retirement and reach your financial objectives. Your goals for retirement are based on your unique situation, and working with a financial advisor can help you create a retirement plan that is customized to your individual circumstances, risk tolerance, timeline, and objectives.

Key Takeaways Your 457 should work alongside your pension to support your overall retirement income plan. Many 457 plans are set on autopilot, but your investments shouldn’t stay that way as you near retirement. Understanding what you're invested in helps you make better decisions when markets move. Turning 50 is your signal to review your 457 more closely so you can check your contributions, risk level, and how it fits with your pension before retirement gets too close. Like many first responders in Washington and Idaho, you probably have a pretty solid grasp of your "Plan A." Between the WA LEOFF Plan 2 or ID PERSI, you’ve spent your career earning a guaranteed monthly pension. It’s the foundation of your retirement — the steady paycheck that arrives regardless of what the stock market does. But then there’s that "other" account. The one you’ve been tucking money into every pay period through deferred compensation. In Washington, it’s usually the Washington State Deferred Compensation Program (WSDCP); in Idaho, it’s often the State of Idaho 457(b) Plan. When we sit down with firefighters and police officers who are within 10 years of their "end of watch" date, they usually know two things about this account: how much is in it and that they’re glad they started it. But when we ask, 'What is that money actually doing?' — that question usually gets a pause. If you’re 50 or older, it’s time to move past the "set it and forget it" mentality. Let’s take a look at how your 457 works and how to make sure it’s working for you. 457 Plan Investment Options  Unlike your pension, which is managed by the state, your 457 is a “defined contribution” plan. That means the outcome depends entirely on how much you put in and how those funds are invested. A 457 plan is just a container. Think of it like a toolbox. What matters is what’s inside the box. Your account isn’t sitting in cash (at least it shouldn’t be). It’s invested in a mix of underlying funds, usually including: Stock funds (equities): These are your growth engines. They tend to go up over time, but they can be volatile. These could be U.S. stock funds or international funds. Bond funds (fixed income): These provide stability and income, but with historically reduced long-term returns. Stable value or cash equivalents: Lower risk, but also lower growth. Most public service 457 plans in the Northwest offer a menu of these options. Some people choose to build their own mix, while others choose a single “all-in-one” fund and let it do the work. This brings us to the most common choice we see… What is a Target-Date Fund? A Target-Date Fund (TDF) is designed to be a one-stop shop. The “date” in the name is the year the fund assumes you will retire. If you plan to hang up the uniform in 2030, you’d likely be in a 2030 fund. A TDF automatically shifts its risk level as you get closer to that date. This is called the glide path . When you are 20 years away from retirement, the fund is aggressive. It buys mostly stocks because you have time to recover from market crashes. As you get closer to the target year, the fund manager automatically “glides” the investments away from risky stocks and into “safer” bonds and cash. TDFs are built for the “average” American worker who relies solely on Social Security and a 401(k), but you aren’t the average worker. You have a LEOFF or PERSI pension. Because your pension acts like a “super bond” (stable, guaranteed income), being too conservative in your 457 might hinder your growth. Conversely, if you’re planning to retire at 53 (common for LEOFF 2) but your fund is target age 65, you might be taking way more risk than you realize. It’s also important to note that two funds with the same year, for example, 2035, can have very different levels of risk depending on the provider. One may still hold 60% in stocks near retirement, while another might be closer to 40%. How Risk Changes as Retirement Approaches In your 20s, 30s, and even early 40s, “risk” is your friend. Risk is what grows a $50,000 account into a $500,000 account. However, as you approach the age of 50, the definition of risk changes. That’s because you’re entering what we call the “retirement red zone,” roughly five years before and five years after your retirement date. This is when: Your portfolio is at its largest You have less time to recover from downturns You may soon rely on the money for income We look at two specific types of risk for our clients: Sequence of Returns Risk: The risk that a market crash occurs just as you start taking withdrawals. If the market drops 20% the year you retire, and you start pulling money out to travel or pay off the mortgage, your account may never recover. Inflation Risk: If you get scared and move everything into the “Fixed Account” or “Stable Value Fund,” you might not lose money, but you’ll lose purchasing power. If your account earns 2% but the cost of living goes up by 4%, you’re technically getting poorer every year. Finding the “Goldilocks” zone — not too hot, not too cold — is the primary job of a pre-retiree. The Age 50 Checklist Once you’re in your 50s, it’s time to stop running on autopilot and take a closer look at your 457. Check Your “Catch-Up” Options In 2026, the standard 457 contribution limit is $24,500; however, once you’re 50, you can add an extra $8,000 in “Age 50 Catch Up” contributions. Even better, if you're within three years of your normal retirement age and haven’t maxed out your contributions in previous years, you may be able to contribute up to double the normal limit ($49,000). This is a massive boost for your savings. Diversify Your Tax Buckets Most first responders have their money in a Traditional 457, meaning you get a tax break now but pay taxes when you take the money out. Both Washington and Idaho offer Roth 457 options. With a Roth, you pay the tax today, but the money grows and comes out tax-free. For high-earners who expect their pension to keep them in a higher tax bracket during retirement, having a “tax-free” bucket of money can be helpful. Coordinate With Your Pension If your LEOFF or PERSI pension covers 70% of your needed income, your 457 can afford to be a bit more aggressive in fighting inflation. If you plan to use your 457 to bridge the gap until you collect Social Security, that money needs to be protected differently. Let’s Take a Look Together At Five Pine Wealth Management, we work with first responders in Washington and Idaho who are approaching retirement and want clarity around their financial picture. We understand how LEOFF Plan 2 and PERSI fit into the bigger picture, and how your 457 can support the retirement you’ve worked hard to build. If you’d like help understanding what you’re invested in, we’d be happy to take a look with you. You can email or call us at 877.333.1015 to schedule. We’d welcome the conversation. You’ve spent your career looking out for the community; let us help you look out for your future. Frequently Asked Questions (FAQs) Q: Is a Target-Date Fund enough for my 457 plan? A: For many people, it is, but as you get closer to retirement, it’s important to review whether the fund’s risk level matches your timeline and overall financial picture. Q: Is there a penalty for taking money out before age 59½? A: No. Unlike a 401(k), the 457 plan has no 10% early withdrawal penalty if you leave your employer, making it an ideal tool for first responders retiring in their early 50s. Q: Should I choose a Target-Date Fund or build my own portfolio in a 457? A: Target-date funds offer simplicity, but building your own portfolio allows for more customization. If you have a pension that already provides a stable income, building your own could be a good option.

Key Takeaways A portfolio designed for accumulation may carry too much risk, or the wrong kind of risk, once you stop contributing. When two spouses are at different financial life stages, their investment strategies should reflect that difference. A Roth conversion strategy during the years before required minimum distributions begin can meaningfully reduce your long-term tax burden. Rob spent 30 years building a picture-perfect financial foundation for his retirement. He maxed out his 401(k) and stayed disciplined through market downturns. By the time he retired from a long career in plant management and HR, he had a nest egg most people only dream about. But then retirement arrived, and with it came a new kind of anxiety. Rob spent all those years learning how to build wealth, but never how to draw it down. The accumulation phase was clear, but the decumulation phase is far more complex and far more personal. Rob had hired a financial advisor when he retired, hoping for guidance through that transition. Instead, he got portfolio management and investment decisions without the broader planning context he needed. That relationship didn’t last a year. And that’s when he and his wife Christie, came to Five Pine. The Numbers Behind the Plan: When They Started Today Rob’s age 57 63 Investable assets $1.1 million $2.5 million Net worth — $3.5 million Primary challenge No decumulation plan, Comprehensive plan in place heavy pre-tax exposure Key strategies Portfolio redesign, Ongoing tax planning, Roth conversion planning rebalancing When Saving Well Isn't Enough When we first met Rob and Christie, a few things stood out right away. Rob was recently retired with $1.1 million in investable assets (the vast majority of it in pre-tax retirement accounts). Christie, about ten years younger than Rob, was still working and earning a high income as a part-owner of a small business. They were a dual-financial-life household: one person winding down, one still in full accumulation mode. Rob’s most pressing concern was straightforward to state but harder to solve: how much could he spend without putting their retirement at risk? He wanted to travel, renovate the house, and buy a new vehicle without second-guessing himself. But after those decades of saving, spending felt foreign, even a little reckless. He had seriously considered going back to work, not because he needed to, but because he felt he couldn’t trust the numbers. Underneath that, a long-term tax problem was simmering. With most of their savings in pre-tax accounts, Rob and Christie were looking at significant required minimum distributions (RMDs) starting at age 73. And Christie, likely to outlive Rob by a meaningful margin, would eventually face those distributions as a single filer at higher tax rates. They weren’t in trouble, but without a plan, they were heading toward unnecessary complexity and tax liability. A Plan Built for Retirement, Not for Accumulation We started with the full financial picture. Before we touched the portfolio, we built a comprehensive financial plan and stress-tested it against different market scenarios, spending levels, and timelines. Once Rob saw the projections running out over a 30-year horizon, his hesitation about retirement began to lift. The plan gave him the number he needed and, more importantly, the confidence to trust it. From there, we redesigned the portfolio to match Rob’s phase of life. He had come from a Dave Ramsey background and had always preferred an all-equity approach: aggressive, growth-focused, and straightforward. That served him well during the accumulation years, when he contributed every month and had decades to recover from downturns. But in retirement and drawing from the portfolio regularly, it introduced more risk than his situation warranted. We restructured his holdings to roughly 60% equities, 25% fixed income, and 15% in alternative investments, specifically private credit funds and private real estate. The alternatives were a meaningful addition. They could potentially carry lower price fluctuation than publicly-traded assets and have the ability to generate distributions, which may potentially help support spending needs without forcing untimely equity sales. Christie's accounts, meanwhile, stayed aggressive. She's still contributing through her employer plan, still has years of earning ahead of her, and has time to weather market swings. Finally, we put a Roth conversion strategy in place for the years ahead. Timed to begin when Christie retires, the strategy takes advantage of a window when their income will likely be lower, but before RMDs kick in and before Christie potentially files as a single filer at higher tax rates. Converting pre-tax dollars gradually reduces the accounts that will eventually be subject to mandatory distributions, potentially saving hundreds of thousands of dollars in taxes over time. From Hesitation to Confidence Rob came to us considering whether he needed to keep working. He left with a plan that showed him that he didn't. Once the plan was in place, Rob and Christie started making the most of their years together, international sailing trips, travel they had put off, and experiences they had earned. A health scare along the way reinforced what the plan had already made clear: the goal is to fund a life worth living while you're healthy enough to live it. On the investment side, market volatility became an opportunity rather than a threat. When markets dropped sharply during a period of economic uncertainty, we rebalanced, selling fixed income to buy equities at a discount. As markets recovered, those moves contributed meaningfully to their overall growth. Five years in, their investable assets have grown from $1.1 million to $2.5 million. Beyond that, Rob and Christie have referred five family members to Five Pine, a reflection of the trust that developed alongside their plan. In Christie's own words: "Ben and Jeremy are honest, approachable, and very professional. They take great pride in getting to know clients and listening to each individual's goals. Honestly, they are the best fiduciaries I have ever worked with, by far." Your Decumulation Strategy Starts Before You Retire Rob's story is more common than most people realize. Disciplined savers often arrive at retirement without a spending plan, a tax strategy, or a portfolio suited to this new phase of life. If you're within five to ten years of retirement (or already there), it's worth asking whether your current advisor is doing comprehensive planning, including tax planning for retirement, or simply managing your investments. Over the course of a long retirement, that distinction can determine whether or not you’re equipped to tackle retirement with confidence. We'd love to help you find your number. Email us at info@fivepinewealth.com or call 877.333.1015. Let's talk.* Frequently Asked Questions (FAQs) Q: When should I start building a decumulation strategy? A: Ideally, five to ten years before you plan to retire. That window gives you time to gradually reposition your portfolio, identify potential tax issues before they become expensive, and stress-test your spending assumptions while you still have income coming in. Q: What role does Social Security timing play in a decumulation plan? A: Claiming Social Security early locks in a permanently reduced benefit, while waiting until 70 can increase your monthly payout substantially. The right timing depends on your health, other income sources, and whether a spouse will eventually depend on your benefit as a survivor. Coordinating with your Roth conversion strategy is also worthwhile, since both affect your taxable income. Q: What happens to my decumulation plan if the market drops early in retirement? A: This is often called the sequence of returns risk. A significant market decline in the first few years of retirement can have a lasting impact on a portfolio, because you're withdrawing funds at lower values. A well-designed decumulation strategy accounts for this by maintaining a portion of the portfolio in less volatile assets, so you're not forced to sell equities at a discount to cover living expenses during a downturn. *Names have been changed to protect client privacy*
