A deferred income annuity, or DIA, takes a premium you pay now and turns it into guaranteed income that does not start until a later date you pick, commonly somewhere between five and thirty years out.
How a DIA works
You fund a DIA with a single premium, or in some cases with ongoing contributions, and pick the date your income is to begin. The carrier locks in your future monthly payment based on your age, your gender in most states, current interest rates, and how long you are willing to wait. The longer that deferral runs, the bigger the eventual check, partly because the insurer gets more years to invest your money and partly because the pool's mortality credits keep building the longer everyone waits to collect. Most DIAs let you choose a single life payout, a joint life option that continues for a spouse, or an add-on like a cash refund if you pass away early in the payout period, though stacking on those features generally lowers the size of the check itself.
DIA vs. QLAC vs. longevity insurance
A DIA built to start paying at 80 or 85 is often called longevity insurance, because its real job is protecting you against the risk of outliving your other savings rather than generating near-term income. A qualified longevity annuity contract, or QLAC, is a DIA held inside an IRA or similar qualified plan. Buying one lets the premium sit outside your required minimum distribution math until payments begin, with income allowed to start as late as age 85.
When a DIA makes sense
A DIA fits best when you still have a long stretch before retirement and want to lock in a future income stream at today's terms while leaving your other assets untouched. Someone in their 50s who buys a DIA set to start paying at 65 or 70 captures years of mortality credits that a person the same age buying a single premium immediate annuity later on would miss out on, which can meaningfully raise the eventual payout for the same premium. Keep in mind a DIA is not a source of liquidity once it is funded: most contracts offer little or no access to the premium before income begins, so it works best for money you are confident you will not need before the start date arrives.
Frequently asked questions
What is a deferred income annuity (DIA)?
It is a contract funded with a premium today that pays guaranteed income starting on a later date you select, often five to thirty years down the road.
What is the difference between a DIA and a QLAC?
A QLAC is a DIA held inside a qualified account, and it keeps that premium out of your RMD calculations until payments begin, up to age 85. A DIA outside a qualified account set to start around 80 or 85 is usually just called longevity insurance.
When does a deferred income annuity make sense?
It fits best when retirement is still a long way off and you want to pin down a future income stream on today's terms while your other savings stay untouched, since waiting longer to start also means a bigger eventual check.
