Why 401(k) Plans Still Struggle to Deliver Guaranteed Retirement Income

Guaranteed income options inside 401(k) and 403(b) plans have been talked about for twenty years. They remain rare. A few reasons stack up: advisors and plan providers make less money when assets go into annuity-like products than when they go into managed accounts or trigger a rollover; small-company plan sponsors mostly don't understand the products; annuities carry a bad reputation; and the products are hard to move when someone changes jobs or when a plan switches record keepers.

SECURE 1.0 gave plan sponsors legal cover to offer guaranteed income, similar to the protection the 2006 Pension Protection Act gave for target-date funds. Target-date funds are now the default in most plans. Guaranteed income products are not. The protection alone didn't do it.

What actually moved the needle on target-date funds was automatic enrollment. Workers were defaulted in, and inertia kept them there. The same mechanism is the only realistic path for guaranteed income options. Without it, most workers will never choose one, and most plan sponsors won't push it.

The practical consequence: 401(k) plans keep functioning as accumulation vehicles, not income plans. Workers who want guaranteed income end up in the retail annuity market, where products are priced for individual buyers rather than institutional ones. The cost difference is real, and it runs against the retiree.

Despite two decades of industry discussion, guaranteed income options — essentially annuity-like products embedded inside workplace retirement plans — remain rare in 401(k) and 403(b) plans. The article identifies several interlocking barriers: advisors and plan providers earn less when money is allocated to guaranteed income rather than managed accounts or rollovers; most plan sponsors at smaller companies don't understand how the products work; annuities carry a poor reputation; and the products are difficult to transfer when a worker changes jobs or a plan switches record keepers. The SECURE 1.0 Act gave plan sponsors some legal protection for offering guaranteed income, but widespread adoption did not follow — unlike what happened with target-date funds after the 2006 Pension Protection Act created similar protections.

The author argues the only thing likely to move the needle is automatic enrollment into a default investment option that includes a guaranteed income component — the same mechanism that dramatically increased participation in target-date funds. Without that nudge, the article contends, 401(k) plans remain savings vehicles rather than true retirement income plans, leaving workers exposed to running out of money in retirement. In the meantime, high-cost retail annuities sold outside workplace plans are booming, which the author frames as a worse outcome for most retirees than an institutionally priced plan-based option would be.
