How long will you need money?

With longevity increasing and retirees wondering if they’ll outlive their nest eggs, some employees are starting to side-eye their 401(k) plans. A 401(k) is a defined contribution plan, meaning the onus is on you to determine how much to put into it and how to invest it, with no guarantee you’ll save enough to last throughout retirement.

It’s no wonder some workers approaching retirement opt for annuities, which guarantee set payments for the rest of your life. And now, some employers are adding annuities to 401(k) plans to help ensure employees won’t run out of money in retirement. But annuities, which are sold by insurance companies, are complex financial products that may not produce the returns you’re looking for and may come with high fees.

Key Points

An annuity is an insurance contract that provides guaranteed income for a set period or for life, depending on the terms.
The SECURE Act made it easier for employers to offer annuities as part of their 401(k) plans.
Although you can compare fees, data doesn’t yet exist on rates of return, and you might not be able to change your mind after locking in an annuity.

The SECURE Act and annuities in 401(k) plans

An annuity contract lets you receive fixed payments for a set time or until you die, depending on the terms. It offers a defined benefit, meaning that you know what you’ll receive each month based on the money you put into it.

Before the passage of the SECURE Act, annuities offered by private employers were typically available outside a retirement plan. In that scenario, upon reaching retirement age, you could take a portion of your nest egg and use it to purchase an immediate annuity, ensuring a reliable, basic level of income.

Building a comfortable retirement typically involves combining Social Security with other sources of income.

The SECURE Act (enacted in 2019) made it less risky for employers to offer annuities. In response, many companies are now more willing to provide annuities inside retirement accounts. Provided employers show they’ve done their due diligence in looking into the financial health of the annuity provider and taking fees into account, annuities in 401(k) plans no longer pose liability issues for companies.

With the passage of the SECURE Act, several financial services companies have introduced 401(k) plans and other defined contribution plans with integrated annuity products, including:

AllianceBernstein (AB)
BlackRock (BLK)
Fidelity
Income America
Nuveen/TIAA
State Street Global Advisors

Does an annuity belong in a 401(k)?

When it’s time to withdraw money from a defined contribution plan, retirees usually have to figure out how much they need to cover expenses without depleting their retirement savings. But annuities, including those incorporated into a 401(k) plan, provide a set monthly payment, reducing the guesswork.

There are three ways to purchase an annuity when it’s linked to your 401(k) plan:

Immediate annuity purchased through the plan. Some 401(k) plan companies, like Fidelity, offer the option of buying an immediate annuity through the retirement plan. Choosing an annuity provider is similar to picking a fund (or funds) in which to invest your money. Review the plan documents and decide which one meets your needs and goals. And just like regular 401(k) plans, those with an annuity component are portable—you can take them with you when you leave your current employer.
Deferred annuity purchased through the plan. Some versions of annuities in 401(k) plans, such as those offered by TIAA and State Street Global Advisors, include deferred annuities. With this approach, employees can invest some of their contributions in annuities to build up over time. Later, they can receive payouts based on a formula that includes how much they’ve saved and other factors.
Target-date fund plus annuity option. BlackRock’s offering combines target-date strategies with an annuity option. These act much like the target-date funds found often in 401(k) and similar plans. But after an employee turns 55, BlackRock switches some traditional fixed-income investments to “lifetime income,” which includes different types of contracts. The kicker is that these are easy to convert to annuities. At age 59½ (or anytime after), the lifetime income funds can be converted to an annuity.

There’s no requirement to use the annuities, and employees don’t have to put all their retirement contributions into them. Workers can decide which portion of their retirement portfolios should be allocated to annuity investments and let the remaining money grow in other investments.

Should I put my 401(k) in an annuity?

Consider your overall retirement strategy before putting your savings in an annuity-linked 401(k) plan, including how many sources of income you expect to have. If your only other expected source of retirement income is Social Security, estimate your monthly Social Security benefit amount to determine whether it’s enough to cover your basic needs. If not, it may make sense to allocate some of your 401(k) plan savings to an annuity that pays you an additional amount each month.

Take your 401(k) annuity with you

Rules that took effect in 2024 allow for 401(k) annuity portability. Before passage of the SECURE Act, you could lose benefits if an employer switched annuity providers. The law eliminated penalties for moving an annuity from one plan to another or rolling it into an individual retirement account (IRA), following the same rules as other rollovers.

Annuities are complex financial products. Deciding whether to purchase one as part of a 401(k) plan (or a stand-alone contract) requires careful consideration:

Review the fees associated with the annuities you’re considering to determine how much they might eat into your returns.
You may incur penalties if you surrender your annuity early.
Upon your death, some annuities may not transfer the remaining value or benefits to your heirs in the most straightforward or cost-effective way.
You typically have 30 days to decide to back out of an annuity. Once you pass that threshold, you’ll be penalized if you change your mind and want to cancel the contract. After you start receiving lifetime payments, there’s usually no going back.
Some annuity-linked 401(k) products have no track record of returns to review, and some annuities aren’t indexed to inflation (unlike Social Security), so your buying power could erode over time.

The bottom line

Increased longevity and the disappearance of defined benefit pension plans in the private sector have left many workers wondering whether they have enough savings to retire comfortably. Even when combined, Social Security and 401(k) savings may not provide sufficient income throughout retirement. Annuities offer a guaranteed income stream. Incorporating them into 401(k) plans makes it easier for workers to convert all or part of their savings when the time comes to retire, ensuring they have money when they need it.

But annuities are complex, often fee-laden, and sometimes inflexible, making them unappealing to many. The SECURE Act has helped by allowing employees in defined contribution plans to transfer annuities between plans or into IRAs without penalties. Still, if you’re considering an annuity-linked 401(k) plan, research fees and understand the terms before you sign on.
