Her Idaho Pension Account Was Credited 9.68% Interest. Cashing It Out Would Cancel the Lifetime Benefit Behind It.
Leaving Idaho public employment with a vested PERSI account can look like a straightforward financial decision until you realize the number on your screen and the benefit behind it are two entirely different things with very different futures.

She spends her career working for an Idaho public employer, then decides in her fifties that it is time for something new. When she logs into her retirement account, the number looks surprisingly healthy. For 2026, the Public Employee Retirement System of Idaho (PERSI) is crediting member Base Plan accounts with 9.68% annual interest, compounded monthly.
She considers rolling the balance into an IRA perhaps to help finance the years before Social Security. A rollover sounds cautious because the money remains tax-deferred. But if she is vested, moving that Base Plan balance out of PERSI does something much larger than changing where her savings are held: it cancels the service credits behind her lifetime pension.
The Number on the Screen Is Not the Pension’s Value
PERSI’s Base Plan is a defined benefit pension, not an investment account whose ending balance determines what she receives in retirement. Her personal account contains her own contributions plus credited interest. Employer contributions go into the pension trust rather than her individual balance and help fund future benefits.
For most members, vesting occurs after 60 months of credited service. Once vested, she has earned the right to a lifetime monthly benefit at retirement even if she leaves Idaho public employment and never returns. The benefit is based on factors including service, age and highest average salary rather than simply paying her account balance back over time.
PERSI makes the difference unusually concrete: its member handbook says most retirees receive back the equivalent of everything they personally contributed within the first three to five years of retirement. The pension can keep paying for the rest of their lives. That is what the account balance does not show.
A Rollover Preserves the Taxes, Not the Pension
Leaving public employment gives her a choice. She can leave her contributions in PERSI, where they continue earning the plan’s annual credited interest, and preserve her service credits. Or she can take a separation benefit consisting of her contributions plus interest.
A direct rollover to an IRA can avoid the immediate federal withholding that generally applies when a withdrawal is paid directly to her. But it does not preserve the pension. PERSI states that either a refund or a rollover of the Base Plan separation benefit cancels all service credits earned toward retirement. The good news is that she does not have to decide simply because she changed jobs. She can leave the account with PERSI after terminating covered employment and preserve the vested benefit for later.
The Pension Can Give Social Security More Room
That lifetime check can become especially useful when Social Security enters the picture. PERSI describes the Base Plan as retirement income designed to supplement Social Security and personal savings. Keeping the pension may give her another income source when deciding whether to claim Social Security at 62, wait until full retirement age (FRA), or delay longer. It does not mean waiting is automatically the right choice. Health, other assets, household needs and the size of both benefits still matter.
Cashing out, meanwhile, can also be perfectly rational. Someone with only a modest vested pension, shortened life expectancy or a strong need for liquidity may value control of the lump sum more highly. The mistake is comparing the account balance with an IRA balance without first putting a dollar value on the lifetime pension being surrendered.
Get the Missing Number Before Choosing
The 9.68% credit is attractive, but the more important number is the monthly benefit that does not appear in the account balance.
- Request a written PERSI retirement estimate showing the lifetime benefit available at the relevant retirement ages. PERSI itself recommends doing this before a vested member takes a separation benefit.
- Compare that income with the actual withdrawal amount, including the employer-funded value that is not refundable and the flexibility the pension could provide around Social Security.
- If liquidity still wins, compare a direct rollover with a cash payout before moving the money. Both cancel Base Plan service credit, but their immediate tax treatment can differ.
Her account balance is real money. The lifetime pension behind it is real money too. The useful choice is not between keeping and taking 9.68%. It is between two different ways of turning a public career into retirement income.
