Immediate vs. deferred annuity: which timing is right for you?
The core difference is when income starts — now, or later. That single choice changes payouts, taxes, flexibility, and who each product is for. Here's the full comparison.
The whole choice comes down to one question: do you want income now or income later? An immediate annuity turns a lump sum into a guaranteed paycheck within about 12 months, while a deferred annuity grows your money first and pays out years down the road. This guide walks through how each works, why the payouts differ, the real numbers, who each one fits, the taxes, the mistakes to avoid, and how to combine both.
The core difference, in one sentence
An immediate annuity (a single-premium immediate annuity, or SPIA) starts paying you within 12 months of purchase. A deferred annuity (a DIA, MYGA, fixed-indexed annuity, or variable annuity) accumulates value first, then either converts to income later or is left to keep growing.
Choosing wrongly is one of the costliest annuity mistakes — you can lock up money you needed liquid, or leave growth and mortality credits on the table by starting too early. The rest of this guide is the clean comparison so you match the product to where you actually are in the retirement timeline.
Immediate (SPIA): income starting now
A single-premium immediate annuity converts a lump sum into a guaranteed stream that begins within roughly a year. It is the purest form of longevity insurance — the older you are when you start, the larger the check, because the expected payout period is shorter and the carrier is funding fewer years.
The catch is liquidity. Once you annuitize a life-only SPIA, the premium is gone as a lump sum — there's no account balance to tap and nothing for heirs unless you added a rider. In exchange you get a paycheck you cannot outlive, which is exactly what makes it powerful for covering essential expenses.

A female buyer's check runs about 4.2% lower at 65 and 7.1% lower at 80, reflecting longer life expectancy. Actual quotes vary by carrier, state, sex and payout option.
Deferred: grow now, income later
A deferred annuity accumulates first, then pays out (or doesn't — you can leave it growing). The deferral phase is where the product family splits:
- MYGA (multi-year guaranteed annuity): grows at a fixed, guaranteed rate for a set term — the annuity world's version of a CD, but tax-deferred.
- Fixed-indexed annuity (FIA): growth is linked to a market index with a floor (often 0%), so you trade some upside for downside protection.
- Deferred income annuity (DIA): bought now to start income at a set future age, often producing a larger payout than a same-premium SPIA because the money compounds and the eventual payout period is shorter.
- Variable annuity (VA): value rises and falls with invested subaccounts, so it carries real market risk — a different animal than the fixed contracts most timing comparisons assume.
Side by side
| Immediate (SPIA) | Deferred (DIA/MYGA/FIA/VA) | |
|---|---|---|
| Income starts | 1–12 months | 2–40 years (or never if not annuitized) |
| Best buyer age | 65–80 | 45–70 |
| Best for | Already retired, need income today | Pre-retiree growing money for future income |
| Liquidity | Usually none once annuitized | MYGA/FIA/VA: some access during deferral (surrender terms apply); DIA: none |
| Premium "wasted" if you die year 1 | Yes on life-only (unless you add period-certain, refund or joint-life protection) | MYGA/FIA/VA: no — cash value passes to heirs; DIA: yes, unless you add a return-of-premium death benefit |
| Tax (non-qualified) | Each payment part return-of-principal, part taxable gain | Tax-deferred growth; gains taxed on withdrawal |
Why annuities pay more per dollar than a CD or bond
SPIAs leverage mortality credits — the actuarial subsidy from buyers who die earlier than expected, whose unused premium funds the survivors' checks. A 65-year-old buying a SPIA starts collecting mortality credits immediately, across roughly 20 years of expected payments. A life-only deferred income annuity bought at 55 to start at 75 earns them across the whole deferral as well — buyers who die before income begins leave their premium in the pool for the survivors — which is why it can price a larger check per dollar.
That extra layer is why a SPIA can pay more than a CD or bond ladder ever could: you're collecting interest, return of principal, and mortality credits at once. No fixed-income instrument matches that. The trade-off is real, though — the deferred contract preserves cash value (legacy potential) and gives you optionality, because you never have to annuitize at all.
Annuities are insurance products regulated at the state level; you can check a carrier's standing and your state guaranty association coverage through the National Association of Insurance Commissioners, and review how products are sold under FINRA rules.
A worked example: $100,000 at 65
Round, illustrative numbers make the timing trade-off concrete. Say you have $100,000 of non-qualified money at age 65.
- Buy a SPIA today: a life-only payout for a man might run about $698/month ($8,376/year) — income for life starting next month, but no balance left.
- Buy a 10-year DIA instead: let it sit, and starting at 75 it might pay roughly $1,525/month because of a decade of compounding plus a shorter remaining payout window.
- Wait and buy a SPIA at 75: if the $100k grows at about 5% for 10 years it becomes roughly $163,000; a life-only SPIA at 75 might pay around $1,470/month.
On these illustrative numbers the two age-75 paths land close together (~$1,525 vs. ~$1,470). The DIA edges ahead, and its bigger edge is certainty: the carrier prices in the mortality-credit advantage at purchase and you've locked in today's interest rates for the full deferral, while the wait-and-buy path depends on actually earning that 5% but keeps a cash value and the option never to annuitize. The SPIA-now option pays the least per month but is the only one giving you a paycheck for the entire decade in between — which matters enormously if you need the income at 65.
| Strategy | Income starts | Approx. monthly income | Income before age 75 |
|---|---|---|---|
| SPIA at 65 | Now | ~$698 | Yes — ~$83,800 collected |
| DIA bought at 65 | Age 75 | ~$1,525 | None |
| Grow, then SPIA at 75 | Age 75 | ~$1,470 | None |
Taxes: how each is treated
Tax treatment depends first on whether the money is qualified (inside an IRA or 401(k)) or non-qualified (after-tax savings).
For non-qualified SPIAs, the IRS applies an exclusion ratio: each payment is split into a tax-free return of your principal and a taxable portion of gain, so part of every check is tax-free until your basis is fully recovered. For deferred annuities, growth compounds tax-deferred and withdrawals come out gains-first — meaning the taxable portion comes out before your principal — with a 10% IRS penalty on gains taken before age 59½.
Inside an IRA or 401(k), the exclusion ratio doesn't apply: the whole payment is ordinary income because the money was never taxed. The mechanics live in IRS Publication 575, and for the early-withdrawal rules see the IRS guidance on retirement-plan distributions.
Which to choose — and who should skip each
This is a decision, so frame it as one:
- Choose immediate (SPIA) when you're retired now and need to convert savings into a paycheck that covers essential expenses for life. Skip it if you might need the lump sum back, or if leaving money to heirs is a priority and you won't add a refund rider.
- Choose deferred when you're still accumulating, want tax-deferred fixed growth, or want to pre-fund larger future income cheaply (a DIA or QLAC). Skip it if you need income immediately, or if you'd be tying up money you can't leave alone through the surrender period.
The "best of both" combo: a DIA at 55, a SPIA at 70
A 55-year-old who buys a DIA today, deferring 15 years, has time for both interest compounding and mortality-credit accumulation. That double advantage is why a DIA locked in early can match or out-pay simply growing the money and buying a SPIA later — the carrier prices the mortality benefit in at purchase, and you've frozen today's interest rates for 15 years, which helps if you believe rates will be lower at age 70.
The other classic hybrid runs the other direction in time: defer with a MYGA during a high-earning year to capture tax-deferred fixed growth, then annuitize into a SPIA later — sequencing growth first and lifetime income second. Either way, you're not picking "immediate vs. deferred" so much as scheduling them.
Mistakes to avoid
- Buying a life-only SPIA when legacy matters. If heirs are a goal, add a cash-refund or period-certain option so the contract returns unpaid premium — you'll trade a slightly smaller check for the protection.
- Deferring too long with no plan to annuitize. A deferred annuity that's never converted is just a tax-deferred savings vehicle; you forfeit the mortality credits that make annuities worth the trade-offs.
- Ignoring the surrender schedule. Penalty-free withdrawals are typically capped near 10% per year; anything more during the surrender period gets hit with charges.
- Not shopping carriers. Payout rates and credited rates vary meaningfully between insurers, and the guarantee is only as strong as the company behind it — verify financial strength and your state guaranty association limits.
