A joint and survivor SPIA promises something that sounds simple: guaranteed income that keeps paying no matter which of you dies first. For a married couple planning retirement income, that's often exactly what you want — and a joint and survivor SPIA can genuinely deliver it. But the survivor percentage you choose is a real purchase, with a real cost in reduced monthly income, contract mechanics that vary more between carriers than most people expect, and one specific risk that rarely comes up in the sales conversation. This guide covers how joint and survivor SPIAs actually work, what each percentage option costs, a contract distinction almost no one explains, and exactly what you're agreeing to when you make the choice.
Take Walter and Renee. Walter is 75. Renee is 69. The $400,000 sitting in Walter's IRA is his — money he built up over a long career before the two of them married. Walter wants to turn part of it into guaranteed income for life, and he wants Renee taken care of if he goes first. That second part feels simple to him: pick the option that keeps paying Renee for as long as she lives. What he hasn't fully considered is that the contract can't know, on the day he signs it, which of them will actually die first — and that uncertainty changes what he's really buying.

Try the SPIA Income EstimatorWhat "Joint and Survivor" Actually Means
A joint and survivor SPIA pays income for two lives instead of one — one structure among the several types of annuities built around different income and growth goals. The person whose age and health mostly drive the pricing is the primary annuitant — usually the one funding the contract. The secondary annuitant (often called the co-annuitant) is the other person covered, most commonly a spouse.
A single-life SPIA stops paying the moment the one covered person dies. A joint and survivor SPIA keeps paying — to whichever of the two people is still living — until the second death. That extra promise is exactly what the contract has to price for, and it's why joint contracts pay less per month than a single-life contract funded with the same premium. You're not just buying income anymore. You're buying income that has to last for however long the longer-living of two people happens to live.
The size of that reduction depends on one specific choice: the survivor percentage.
The Percentage Choice — 100%, 75%, 50%, and Sometimes 66⅔%
When Walter elects a joint and survivor SPIA, he isn't just deciding whether Renee gets income after he's gone — he's deciding how much of the original payment continues. The most common choices, in order of what they cost:
| Survivor Option | What It Means | Illustration Only — $400,000 Premium |
|---|---|---|
| 100% Joint and Survivor | Payment stays exactly the same after the first death | Roughly $2,150/month while both are living; same amount continues to the survivor |
| 75% Joint and Survivor | Payment drops by a quarter after the first death | Roughly $2,280/month while both are living; about $1,710/month to the survivor |
| 66⅔% Joint and Survivor | Payment drops by about a third — offered by some carriers, not all | Roughly $2,340/month while both are living; about $1,560/month to the survivor |
| 50% Joint and Survivor | Payment is cut in half after the first death | Roughly $2,410/month while both are living; about $1,205/month to the survivor |
Illustration only, not a quote. Actual figures depend on both ages, sex, the carrier, and current rates — see the estimator above for your specific numbers.
The pattern is always the same: the higher the guarantee to the survivor, the lower the payment while both people are alive. There's no way around that trade-off — it's the same mechanic behind every refund option on a SPIA. You're paying, in reduced current income, for a promise about the future. For the full breakdown of how this compares to the other SPIA payout options, see SPIA Payout Options Compared.
Two Different Contracts Called "Joint and Survivor"
Here's something most explanations of joint and survivor annuities skip entirely — and it can genuinely surprise people who assumed otherwise.
Most people assume the survivor percentage works the same way no matter which of the two annuitants dies first. That's a reasonable assumption. It's also not always true.
Some contracts are built symmetrically: the survivor percentage applies no matter which annuitant dies first. If Walter dies first, Renee's payment drops to the elected percentage. If Renee dies first, Walter's payment also drops to that percentage.
Other contracts are built asymmetrically — sometimes described as "joint life to spouse" rather than "joint life to survivor." In this structure, the reduction only triggers if the primary annuitant dies first. If Walter (the primary) dies first, Renee's payment drops to the elected percentage, exactly as expected. But if Renee dies first, Walter's payment doesn't drop at all — he continues receiving 100% of the original payment for the rest of his life, because the contract was really built to protect Renee's continuation, not the reverse.
Both designs are legitimately called "joint and survivor." Which one a person has depends entirely on how the specific contract is written — not on what the sales conversation implied, and not on what seems intuitive. Before assuming you know how your contract behaves in every order of death, check the actual policy language, or ask the carrier directly which structure applies.
You're Insuring an Outcome You Can't Know Yet
This is where Walter and Renee's decision gets uncomfortable to look at directly — and it's worth looking at directly anyway.
Walter elects a joint and survivor SPIA specifically because he's picturing one outcome: he dies first, Renee lives on with reduced income, and the reduced payment is there for her because he planned for it. That's a real, common, and completely reasonable thing to plan for.
But say Renee dies first instead — five years into the contract, at 74. Walter is now 80. Under a symmetric contract, his payment drops to whatever percentage he elected, for the rest of his own life — a reduction he bought to protect Renee, that Renee never used, and that now simply lowers Walter's own income for as long as he lives. He's not protected by the choice he made. He's the one paying for it.
That's the part a reduced survivor percentage doesn't advertise: you're not protecting your spouse. You're buying a death benefit for whichever of you turns out to survive — an outcome that's genuinely unknown on the day you sign, no matter how likely one order feels based on age or health at the time.
What the IRS Actually Requires (Correcting a Common Myth)
A lot of consumer content states, flatly, that "the IRS requires joint and survivor annuities to pay the survivor between 50% and 100%." That's true — but only in one specific context, and most of the content repeating it doesn't say which one.
That 50%–100% rule comes from ERISA's Qualified Joint and Survivor Annuity (QJSA) requirement — a federal rule that governs the default payout form for married participants in an employer-sponsored pension or qualified retirement plan (29 U.S.C. §1055). It exists to keep one spouse from signing away the other spouse's retirement income without consent.
That rule does not bind a SPIA you buy directly from an insurance company outside of a qualified plan. A commercial carrier selling you a joint and survivor SPIA can offer whatever range of survivor percentages it chooses — some may cap options at a 50% floor as standard practice, but nothing in federal law requires it for a contract purchased this way. If you're comparing survivor percentages on a SPIA you're buying yourself, you're shopping carrier menus, not federal minimums.
How Joint and Survivor Income Is Taxed
If your SPIA is funded with after-tax money, part of every payment comes back to you tax-free — that's the exclusion ratio, and we walk through the full mechanics in How a SPIA Is Taxed. A joint and survivor contract uses a different table than a single-life SPIA, and it's worth knowing why before you assume the two work the same way.
A single-life SPIA's exclusion ratio uses IRS Table V, keyed to one person's age. A joint and survivor SPIA uses IRS Table VI instead, which reflects the combined life expectancy of both annuitants — and because a two-life payout is statistically likely to run longer than a one-life payout, the Table VI multiple is always larger than the Table V multiple for the older annuitant alone.
Here's an IRS-published example of the mechanic (not Walter and Renee's numbers): a person age 70 and their spouse age 67 buy a joint and survivor SPIA. The single-life Table V multiple for a 70-year-old is 16.0. The joint Table VI multiple for ages 70 and 67 together is 22.0 — noticeably larger. A larger multiple means a larger expected return in the exclusion-ratio formula, which generally means a smaller percentage of each payment comes back tax-free compared to what a single-life SPIA at the same premium would produce.
The practical takeaway: don't assume your joint SPIA's tax-free percentage will match what a single-life exclusion-ratio example shows you. It's a different calculation, on a different table, and it's usually a lower percentage. If your premium came from a retirement account instead of after-tax savings, the exclusion ratio doesn't apply the same way at all — see SPIA Funded by an IRA vs. After-Tax Savings.
Not tax advice. This is a simplified educational walkthrough, not a substitute for your own tax return preparation. Qualified-money SPIAs, contracts with a refund feature, and pre-1987 contracts follow different rules.
An Alternative Worth Knowing About
Some couples solve the "unknown survivor" problem a different way: instead of reducing the SPIA's payout to fund a survivor percentage, they take the higher single-life payout and buy a separate life insurance policy on the older spouse instead. That approach stays flexible in a way a locked-in survivor percentage doesn't — if the younger spouse dies first, the policy can keep being funded, be surrendered, or in some cases be sold in the life settlement market, rather than simply lowering income for the rest of the survivor's life with no way to undo it.
It doesn't work for every couple, and it isn't free — a separate policy has its own cost and underwriting to work through. But it's a real option worth knowing exists before you assume the survivor percentage on the annuity itself is the only way to protect a spouse.

Frequently Asked Questions
What percentage should we choose for a joint and survivor annuity?
It depends on how much income the surviving spouse would need on their own — Social Security, other savings, and other guaranteed income all factor in. There's no single right answer; it's a question of how much of the gap this specific contract needs to close.
Can a joint annuitant be someone other than my spouse?
Generally yes — many carriers allow a non-spouse co-annuitant. Rules and available percentages can differ from spousal contracts, so confirm the specifics with the carrier before assuming the terms match a spousal joint and survivor SPIA.
What happens if my joint annuitant dies before me?
It depends on how the contract is structured. Under a symmetric ("joint life to survivor") contract, your own payment drops to the elected percentage, just as it would if you died first. Under an asymmetric ("joint life to spouse") contract, your payment may continue unchanged. Check your specific contract language — this is exactly the distinction covered above.
Does the IRS require a joint and survivor annuity to pay at least 50%?
That rule applies to Qualified Joint and Survivor Annuities under employer-sponsored retirement plans, not to a SPIA you purchase directly from an insurance company. Commercial carriers set their own available survivor percentages.
Is a joint and survivor annuity taxed differently than a single-life annuity?
Yes, if it's funded with after-tax money. Joint contracts use IRS Table VI instead of Table V, which generally means a smaller percentage of each payment is tax-free compared to a single-life SPIA at the same premium.
