Types
Companies who administer 401(k)s such as Fidelity Investments, do indeed offer annuities to their clients. However, the choice is severely limited. I believe the only one available is SPIA (Single Premium Immediate Annuity).
Considerations
Here’s how they work. When purchased, you agree to lifetime income for a certain period, such as for ten or fifteen years. Let’s say I put all my retirement funds in this product and I receive a monthly check from the annuity company and have been doing so for ten years. If I die, the money left in my account will NOT be passed on to my heirs; the annuity company keeps it. The reason why is because I would have used up my protection living for more than ten years. Or, if I had a fifteen-year annuity and I died in year ten, my heirs would receive the monthly checks for another five years, and the company keeps the rest.
This will not fit most retirees’ needs.
Security
Make sure the insurance company offering the annuity has solid financial strength ratings from rating agencies like AM Best. And check out how annuity fees and payments compare to available annuities outside of your 401(k).
Other Options
Finally, there is an advanced deferred annuity funded by an investment from a retirement plan. This is called the qualified extended annuity contract (QLAC). As of January 1, 2021, an individual can use up to $135,000 from their retirement savings account to purchase QLAC.
Annuities vary, there are many that provide fixed income for life. With some, you can specify how long you want to continue receiving payments. The security of knowing exactly how much to expect from one source of income can provide peace of mind in retirement.
Another option is a joint life with last survivor annuity which costs more, but provides for a surviving spouse. This fixed income for life is ideal for couples needing to provide fully for both people. See more below.
