- A direct rollover moves 401(k) money into an IRA annuity without tax; taking receipt yourself triggers mandatory 20% withholding and a 60-day clock.
- Tax deferral is not a reason to do this — the 401(k) and the IRA already defer. If that is the pitch, the pitch is wrong.
- The legitimate reasons are guarantees the account cannot produce on its own: lifetime income, principal protection, or a QLAC's RMD relief.
- Rolling out of a 401(k) can cost you institutional pricing, creditor protection under ERISA, and the rule of 55.
- Once inside an annuity, the money is subject to a surrender schedule that a 401(k) never had.
This is one of the highest-commission transactions in retail financial services, which does not make it wrong — but it does mean the recommendation arrives with more energy behind it than most. The mechanics take two paragraphs. The decision takes the rest of the page.
How the rollover works
The correct method is a direct trustee-to-trustee rollover: your 401(k) administrator sends the money straight to the IRA custodian holding the annuity. Nothing is withheld, nothing is taxed, and there is no deadline to miss.
The method to avoid is an indirect rollover, where the plan pays you and you redeposit within 60 days. Two traps. The plan must withhold 20% for federal tax, and to complete the rollover you must deposit the full original amount — making up that 20% from other money and waiting for a refund at filing. Miss the 60-day window and the shortfall is a taxable distribution, with a 10% additional tax on top if you are under 59½.
Ask explicitly for a direct rollover, and confirm the check is payable to the receiving custodian rather than to you.
The reason you will be given, and why it is wrong
Tax-deferred growth is the annuity's headline feature, and it is the reason most often cited for this move.
It does nothing here. A 401(k) already defers. An IRA already defers. Moving money from one deferred account into an annuity inside another deferred account adds no deferral, because you cannot defer what is already deferred. This is not a subtle point or a matter of degree — the benefit is exactly zero, and our qualified-money guide covers why.
So the practical test is simple: if tax deferral is doing the selling, the pitch is describing a benefit you already own. That alone is enough to send the proposal for a second opinion.
The reasons that are real
An IRA cannot guarantee anything on its own. It cannot promise income for life, it cannot floor your principal, and it cannot remove its own value from your required distribution calculation. Annuities can do all three, and each is a legitimate reason to bring one inside qualified money.
Lifetime income. If your essential expenses exceed Social Security and any pension, an annuity converts part of the balance into income that cannot be outlived. That is a real transfer of longevity risk and no allocation achieves it.
Principal protection. For someone genuinely unable to tolerate a drawdown in the years around retirement — when sequence risk is at its worst — a floor has real value, and it should be priced against what a MYGA guarantees for the same money.
A QLAC. The exception that genuinely earns its place inside an IRA. A qualifying longevity annuity contract removes its own value from the RMD calculation until payments begin, as late as 85. That is the one structure that reduces forced distributions rather than being subject to them, and no non-annuity product does it.
What you leave behind
The rollover conversation rarely covers this side, and it should.
Institutional pricing. Large plans frequently offer share classes cheaper than anything available at retail. Pull your plan's fee disclosure and compare before assuming the IRA is cheaper.
ERISA creditor protection. 401(k) assets carry broad federal protection from creditors. IRA protection exists but varies by state and is generally narrower. If asset protection matters in your situation, this is a real consideration rather than a technicality.
The rule of 55. If you separate from service at 55 or later, you can take penalty-free withdrawals from that employer's plan. Roll the money to an IRA and the exception is gone — you are back to 59½ or a 72(t) schedule. For anyone retiring in their late fifties this can matter more than anything the annuity offers.
Plan-specific options. Stable value funds in particular have no retail equivalent and are frequently the best conservative option a retiree has access to.
And what you take on
A 401(k) has no surrender schedule. An annuity does — commonly seven to ten years, occasionally longer, frequently paired with a market value adjustment. Money that was fully liquid becomes money with an exit price.
You also concentrate. A 401(k) holding index funds spreads across thousands of issuers. An annuity is one promise from one insurance company, and above your state guaranty limit there is no backstop. Rolling a large balance into a single contract can put most of a retirement above that line.
Why "roll over the whole thing" is the wrong shape
Guaranteed income exists to cover a gap: essential expenses minus Social Security minus pension. That number is usually a fraction of a retirement balance.
A partial rollover — enough to buy the income the gap requires, leaving the rest invested and liquid — gets the guarantee where it matters and keeps flexibility everywhere else. It also keeps the premium inside the guaranty limit and preserves the option to do something different in five years.
Whole-balance rollovers solve for the commission rather than the gap. That is not an accusation about any individual recommendation; it is an observation about which version of this transaction pays more, and a reason to ask why the number proposed matches your entire balance rather than your actual shortfall.
Five questions before you sign
Which specific guarantee am I buying, and what does it cost annually? What is the surrender schedule by year, and is there a market value adjustment? How does my plan's all-in fee compare to the IRA's? What am I giving up — rule of 55, ERISA protection, a stable value fund? And how much of my balance does the income gap actually require, as opposed to what is being proposed?
An adviser who answers all five in writing is being straight with you. The fifth is the one that most often changes the size of the transaction.
