In-Plan Lifetime Income in a 403(b): What It Is, and What It Isn't

What is in-plan lifetime income?

It is a feature that converts part of a participant's 403(b) balance into guaranteed income for life, built directly into the plan rather than sold as a separate product they have to go find. For a nonprofit workforce that often has no traditional pension, it answers the question a 401(k) or 403(b) never solved on its own: how do I turn a pile of savings into a paycheck that lasts as long as I do?

The word to hold onto is option. This is not the employer promising a benefit. It is the plan giving each participant a way to buy lifetime income with their own money, on institutional terms, if and when it fits their situation.

What did SECURE 2.0 change?

It made lifetime income practical to offer inside a plan. Before, plan sponsors hesitated to add annuities, partly out of fear of being sued if the insurer later failed. The SECURE Act created a fiduciary safe harbor for prudently selecting an annuity provider, and SECURE 2.0 built on it. A few of the changes that matter:

• A safe harbor that gives sponsors a clear process for choosing an annuity provider, so offering one is less risky.
• Portability, so a participant can roll over or keep an in-plan annuity if the plan later drops the option, without a surrender penalty.
• A higher, simpler limit on qualifying longevity annuity contracts (QLACs), the deferred annuities that start income later in retirement.
• Annual lifetime-income illustrations on participant statements, translating a balance into an estimated monthly income.

How does the in-plan annuity path actually work?

In a modern pooled 403(b), it often runs through the plan's default investment. A participant who never opts out can be placed in a qualified default investment alternative that starts as a target-date fund, shifts toward a managed account as they age, and, depending on their profile, directs a portion toward an in-plan annuity that provides income in retirement. Someone who wants to choose actively can do the same on purpose.

The important nuance: this is a framework, not a promise that every participant ends up with a guaranteed pension. What each person receives depends on how much they saved, what they elect, and the terms of the annuity. If you want to see the shape of the tradeoff, you can estimate the monthly income a given premium could buy and change one number at a time.

Keep it invested, or annuitize? The real tradeoff

Neither choice is automatically right. Annuitizing buys longevity protection at the cost of liquidity and growth. Staying invested keeps flexibility at the cost of certainty. Most people are best served somewhere in the middle, annuitizing enough to cover essential expenses and keeping the rest invested.

This is the same question RTX employees face with their plan's guaranteed income option, which I walk through in the RTX lifetime income review. The plan is different, the decision is the same.

Who is this for, and where does it fit?

In-plan lifetime income tends to matter most for employees without a pension and without a spouse's guaranteed income to lean on. For a nonprofit deciding whether to offer it, the feature is one reason a modernized or pooled 403(b) is worth a look, which I cover on my nonprofit 403(b) plan advisory page and in the guide to pooled employer plans for nonprofits.
