Oregon Savings Growth Plan: What It Is and How to Use Yours

ByRobby Naka

The Oregon Savings Growth Plan sounds like a rebrand of every retirement plan you have ever heard of. It is not. It is a very specific animal, a 457(b), and if you work for the state of Oregon (or a city, county, school district, or other public employer on PERS), it is the account sitting right next to your pension waiting to be filled.

The first time someone at work told me about 457(b) plans, I nodded like I understood every word and then went home and Googled it. I thought it was a tax-loophole thing for people richer than me. It is not. It is a boring, useful retirement account with one twist that changes retirement math in your favor, and it is available to you today.

The Oregon Savings Growth Plan is a voluntary retirement account that sits on top of your PERS pension, filling the gap your pension and Social Security alone will not cover.

What the Oregon Savings Growth Plan actually is

OSGP is Oregon’s flavor of a 457(b), the retirement account bucket built for people who work for the state, the city, the schools, that kind of gig. Think of it as the public-sector cousin of the 401(k) with a few better rules baked in. It is a defined contribution plan, which means you (the participant) put the money in, the account grows tax-advantaged, and how much you have at the end depends on what you contributed and how it grew, not a fixed promise from an employer.

Three players run the plan in tandem: the Oregon Investment Council chooses the fund menu, State Street Bank sits on the money as custodian, and Voya keeps the records, so Voya is the one whose site you actually log into. It is available to any employee of a PERS-participating employer, which covers state agencies, most cities and counties, and school districts. You can enroll at any time, and the minimum contribution is $25 per pay period. That is intentional. The point is to get you in the door with a number small enough that nobody has a real excuse to keep waiting.

Here is how it fits with the rest of your retirement setup. Social Security usually picks up about 20 to 30 percent of what you were earning before you retired, and that’s it. PERS covers up to about 45 percent depending on how long you worked. That leaves a gap of roughly 25 to 40 percent of your income that someone still has to fund. That someone is you. The Oregon Savings Growth Plan is the container Oregon built for you to do exactly that.

OSGP vs. OregonSaves, the two Oregon plans people mix up

Every time I search anything with “Oregon” and “savings” in it, the top results are half OSGP and half OregonSaves. They are not the same thing and getting them confused will cost you real money, so let’s split them cleanly.

OSGP is what you have if you work for a public employer that participates in PERS. It is a real workplace retirement plan, a 457(b), with contribution limits well over $20,000 a year, real investment options, and a Roth choice. It is what this post is about.

OregonSaves is a totally different animal. It is Oregon’s state-run Roth IRA program for private-sector workers whose employer does not offer a retirement plan. If your paycheck comes from a coffee shop, a small design studio, or a five-person landscaping business, and they auto-enrolled you at 5 percent of pay, that is OregonSaves. It is a Roth IRA, so its cap is the IRA cap (a fraction of the 457(b) cap), the tax treatment is different, and the investment lineup is a much smaller menu.

The short version: if you get a state or city or school-district check, OSGP is yours to use. If you work private-sector and your job uses OregonSaves as its retirement offering, that is a different account with different rules.

The 2026 contribution limits (and the 3-year catch-up)

The IRS sets the limits, so they apply to every 457(b) in the country, but here is what they land at inside OSGP for 2026:

  • Under age 50: $24,500 for the year
  • Age 50 to 59, or age 63+: $32,500 for the year (the standard limit plus an $8,000 catch-up)
  • Age 60 to 63: $35,750 for the year (the SECURE 2.0 “super catch-up” window)

There is one more layer that only 457(b) plans get, and it is the reason I keep telling public-sector friends to pay attention to their OSGP. If you are within three years of “normal retirement age” (usually the earliest age you can take a full unreduced PERS pension), you can use a special 3-year catch-up that lets you contribute roughly double the standard limit, up to about $49,000 in 2026, using any unused contribution room from prior years. You cannot combine the age-50 catch-up and the 3-year catch-up in the same year, so pick one.

One quiet win that goes with a public-sector job: if you also have access to a 403(b), you can contribute the full IRS limit into a 403(b) and the full limit into OSGP in the same year (unlike the 401(k) and 403(b) pair, which share a limit). See the current numbers at the IRS 457(b) contribution limits page.

Roth 457 vs. pre-tax, the real fork in the road

When you enroll in the plan, you pick pre-tax, Roth, or both. Do not overthink this the first time. Do think about it once.

Pre-tax means the contribution comes out before income taxes are calculated, lowering your taxable income right now. You will pay income tax later when you pull the money out in retirement.

Roth 457 means the contribution goes in after taxes, so you get no tax break today, but everything (your contribution and every dollar it earned) comes out tax-free in retirement.

The real question is boring and useful: is your income tax rate lower right now, or lower in retirement? Early-career, in a lower bracket, still climbing? Roth tends to win, because you are locking in a low rate you may never see again. Peak-earning, in a high bracket, in a state with income tax? Pre-tax tends to win, because you are dodging tax at your top rate today and paying it back at whatever your average rate is in retirement. Somewhere in the middle, or unsure? Split the contribution between them. That is a perfectly reasonable move, and one nice thing about Roth 457 (versus a Roth IRA) is that there is no income limit that phases you out.

Your investment options at a glance

Once your money is in the plan, it has to sit in something. OSGP offers around a dozen pre-vetted investment options plus a self-directed brokerage window if you want to go off-menu. The main lineup:

  • LifePath target-date funds (the default). You pick the one dated closest to when you plan to retire; it holds a mix of stocks and bonds that slowly gets more conservative as that date approaches. This is the “set it and forget it” option, and for most people it is the right answer.
  • Stable Value fund. Boring on purpose. Behaves like a slightly-better-than-bond fund. Used mostly by people close to retirement.
  • Stock index funds. Large-cap US, small-cap US, and international. Cheap, broad, and what most long-term money should sit in if you are building your own mix.
  • Real return fund. Aims to keep pace with inflation.
  • Socially responsible option for the values-driven crowd.
  • Self-directed brokerage for the small percentage of people who want to buy individual funds or ETFs outside the main lineup.

If none of that got you excited, good. Pick the LifePath fund closest to your target retirement year and move on with your life. You can always change it later.

The 457(b) withdrawal rule that changes retirement math

This is the part I wish someone had told me sooner. Every retirement account most people know about (401(k), 403(b), Traditional IRA) hits you with a 10 percent penalty if you pull money out before age 59 and a half. The 457(b) does not.

The 457(b) is the one retirement account where the door opens early. Separate from the employer, and the 10 percent early-withdrawal penalty simply does not apply.

Once you separate from service, meaning you retire, quit, get laid off, or leave the public employer for a private job, you can withdraw money from your OSGP account at any age with no early-withdrawal penalty. You still pay income tax on pre-tax dollars when you take them out, but you dodge the 10 percent surtax that would apply to a 401(k). That makes OSGP one of the best “bridge” accounts for anyone considering early retirement. If you plan to stop working at 55 and want to live off something until Social Security and PERS kick in a few years later, this account is where that money can come from without a tax slap.

There is a warning attached. The moment you roll a 457(b) into an IRA, the account you rolled into follows IRA rules, which means the 59-and-a-half penalty comes back. If early access is part of your plan, leave OSGP alone until you actually need it, or roll it carefully. For the deeper comparison to a similar public-sector plan, see how the Thrift Savings Plan works for federal employees. Same idea, slightly different rules.

How to enroll and set it up in one afternoon

You do not need a financial planner or a spreadsheet for this. You need about 45 minutes.

  1. Go to the OSGP portal at growyourtomorrow.com (Voya’s OSGP site) and start an enrollment. Have your PERS or employee ID handy.
  2. Pick a contribution amount. Either a percentage of pay (recommended, because it scales automatically with raises) or a flat dollar amount per pay period. Start where you can. A percentage as small as 3 percent is fine on day one.
  3. Pick pre-tax, Roth, or a split. Use the guidance in the fork section above; if you are early-career, the Roth 457 is usually the easier call.
  4. Pick your investment. LifePath fund dated closest to when you plan to retire is the boring, correct answer for most people.
  5. Turn on auto-escalation. This bumps your contribution up by 1 percent a year until you tell it to stop. It is the single highest-leverage checkbox in the plan.
  6. Name a beneficiary. Do not skip this. This is the step most people forget, and it is the one their family will care about most.

Once it’s set up, close the tab and go live your life. Check the balance twice a year, tops. Bump your contribution by 1 percent every raise. That is the entire long-run game. For a wider primer on how workplace retirement accounts fit together, the 401(k) plan explainer covers the private-sector cousin and how the pieces stack.

The Oregon Savings Growth Plan is not glamorous. That is the whole appeal. It is an automatic, tax-advantaged container that fills the gap your PERS pension will not cover, with a withdrawal rule most retirement accounts would kill for. Pick a percentage, pick a LifePath fund, name a beneficiary, and go live the rest of your day.
