Income Annuities for Married Couples: SPIA, DIA, and QLAC Explained

An income annuity converts a lump sum into guaranteed monthly income you can't outlive. For married couples, the calculus is different from single retirees: you're planning for joint longevity, you face a critical and often irreversible survivor-income decision at purchase, and one specific type — the QLAC — lets each spouse shelter up to $210,000 from required minimum distributions, for a combined $420,000 per household in 2026.

The Retirement Income Floor Problem

Every couple in retirement faces the same structural question: how much of our spending is covered by income we can't outlive, regardless of what markets do?

Social Security is the most powerful guaranteed income source most couples have. For a typical dual-income couple retiring in 2026, combined SS income ranges from roughly $3,000 to $6,000/month — more if one spouse worked a high-earning career and delayed to 70. That may cover essential expenses but often falls short of full lifestyle spending.

The gap between the guaranteed floor and total spending must come from the portfolio. That gap creates sequence-of-returns risk — the danger that a market downturn early in retirement forces the couple to sell assets at the worst possible time, permanently impairing the portfolio's ability to support 25–30 years of withdrawals.

Adding an income annuity raises the guaranteed floor and shrinks the gap the portfolio must cover. A married couple's joint longevity makes this more important than for singles: the probability that at least one spouse lives to 90 is roughly 50%, and to 85 is closer to 70–75%.¹ Sequence-of-returns risk applies across the full joint horizon, not just one individual's life expectancy.

Three Types of Income Annuities

All three convert a premium into lifetime income. The structural differences are when payments start, where the money comes from, and how payments are taxed when you receive them.

Tax treatment at payout:

• SPIA/DIA funded from a taxable account: Each payment is part return of principal (tax-free) and part earnings (ordinary income). The exclusion ratio is set at purchase.
• SPIA/DIA funded from a Roth IRA: Qualified distributions are fully tax-free.
• Any annuity funded from a traditional IRA or 401(k): 100% of each payment is ordinary income, the same as any other pre-tax withdrawal.

QLAC: The RMD Management Tool for Couples

A QLAC is a deferred income annuity with one special feature: the amount you place into a QLAC is excluded from your RMD calculation until the annuity starts paying. You don't owe a required minimum distribution on that money during the deferral period — it sits outside the RMD base entirely.

2026 limits:²

• $210,000 per spouse (inflation-adjusted under SECURE 2.0 Section 202; the base was $200,000 at enactment, indexed to $210,000 for 2026)
• $420,000 per couple — each spouse has an independent limit applied to their own accounts
• Maximum deferral age: 85 — payments must begin no later than the first day of the month following your 85th birthday
• Must be purchased from a qualified retirement account only (traditional IRA, 401k, 403b, or governmental 457b)

QLAC vs. Roth conversion: Both strategies reduce a large traditional IRA balance (and future RMDs), but in different ways. A Roth conversion pays income tax on the converted amount now, moves money into a tax-free and fully flexible account, and leaves assets to heirs with no RMD obligations. A QLAC further defers the tax to age 85+, gives up liquidity, and converts the premium into an income stream rather than an inheritable asset. Many couples with large IRAs benefit from both: Roth conversions in the 60s to bring the pre-tax balance to a manageable range, and a QLAC to handle the portion that remains in traditional accounts.

The Joint-and-Survivor Decision

This is the most consequential annuity decision married couples make — and for most products, it's irrevocable.

When you purchase an income annuity as a couple, you choose the continuation percentage: the share of the original monthly payment that the surviving spouse receives after the first spouse dies.

The payout reduction for joint annuities is actuarially fair — it reflects the cost of providing lifetime income to a second person. The "right" percentage depends on how financially dependent the surviving spouse would be on that income stream after the first death.

When 100% joint and survivor makes strong sense:

• One spouse has little or no independent income — no pension, small Social Security benefit
• The annuity represents a large share of the household's guaranteed income floor
• The healthier or younger spouse is likely to outlive the other by many years

When a lower percentage (or single-life) can make sense:

• Both spouses have substantial independent income sources — two pensions, strong SS benefits from both careers
• The annuity is a small slice of total retirement income, not the primary floor
• One spouse has significantly shorter life expectancy due to known health conditions

ERISA protection for pension plan elections: If your decision involves a defined-benefit pension covered by ERISA — not a purchased annuity from an insurance company — federal law requires the default election to be a Qualified Joint and Survivor Annuity (QJSA) at no less than 50% survivor benefit under IRC §§ 401(a)(11) and 417.³ Choosing a lower percentage or single-life option requires written spousal consent notarized or witnessed by a plan representative. This legal protection has prevented many spouses from being financially devastated when the pension-holding spouse died. Purchased annuities from insurers carry no equivalent legal requirement — but the same planning logic applies.

How Annuities Interact With Social Security

For most couples, Social Security is the first guaranteed income decision to optimize — before purchasing any annuity. Delaying the higher earner's SS to 70 increases their benefit by 8% per year after Full Retirement Age,⁴ and that larger benefit becomes the surviving spouse's permanent income floor. No annuity available on the market offers an 8% guaranteed annual return with built-in survivor coverage. Optimize SS first.

With that foundation, annuities and Social Security interact in two productive ways:

1. Annuity bridge for early retirees: If you retire at 62 or 65 but delay SS to 70, you have a 5–8 year income gap. A DIA purchased at retirement to start paying at 70 (or a SPIA on a portion of savings) provides guaranteed income during the bridge years without forcing large portfolio withdrawals early in retirement when the sequence-of-returns risk is highest.
2. Late-life income above SS via QLAC: SS continues to age 85, 90, and beyond — but healthcare and care assistance costs typically peak in the final decade of life. A QLAC starting at 85 adds a guaranteed income layer at exactly that point, funded from assets that would otherwise be subject to RMDs in the 73–85 window.

When Annuities Make Sense for Couples

• Essential expenses exceed your guaranteed income floor. If SS plus any pension doesn't cover fixed expenses, an annuity is a direct solution — not a hope that markets cooperate.
• You have a large traditional IRA and expect high RMDs. A QLAC directly reduces the RMD obligation and creates guaranteed late-life income from an account that would otherwise generate unwanted taxable distributions.
• One spouse has significantly lower income or SS benefit. The survivor income protection of a joint annuity may be worth the lower current payout, particularly if that spouse is younger or healthier.
• Both spouses have strong family longevity history. Annuities pay off more when one or both spouses live well into their 80s and 90s. The break-even age for a 65-year-old buying a SPIA is typically in the early 80s — couples with long-lived family trees are likely to clear that hurdle.
• You want a simpler retirement income structure. Retirees who find systematic withdrawal decisions stressful benefit from having a meaningful portion of income arrive automatically each month without portfolio decisions attached.

When They Don't Make Sense

• Your guaranteed income floor already covers essential expenses. No income gap means an annuity trades liquidity for income you'd already have from SS and any existing pensions.
• One or both spouses has a health condition that shortens life expectancy. Annuity pricing assumes average mortality. If you have reason to expect a significantly shorter-than-average life, you may not collect long enough to break even — and the premium passes to the insurer, not your heirs.
• Estate transfer is the primary goal. Pure income annuities have no residual value for heirs once the premium is paid. Refund-of-premium or period-certain riders add some estate value but at the cost of lower monthly income.
• Interest rates are at historical lows. Annuity payouts track long-term interest rates. In low-rate environments, bond ladders or dividend-producing portfolios may provide comparable income with more flexibility.

Common Mistakes Couples Make With Annuities

• Taking a single-life pension election without understanding the survivor impact. This is the most common — and most financially devastating — couples annuity error. A retiree maximizes their current pension payout with a single-life election, and the lower-income spouse loses the majority of household income within days of the retiree's death. This mistake is irreversible.
• Confusing a variable or indexed annuity with an income annuity. Variable and indexed annuities are investment products wrapped in insurance features, often sold with high commissions, complex surrender charges, and benefit riders that add cost without clarity. If the goal is guaranteed monthly income, a straightforward SPIA or QLAC from a highly-rated carrier is usually simpler, cheaper, and easier to evaluate.
• Annuitizing too large a fraction of assets. Locking up a large share of savings eliminates flexibility for healthcare emergencies, care costs, or estate planning changes. The general principle: annuitize enough to close the income gap, not the entire investable portfolio.
• Ignoring inflation. A fixed annuity payout loses purchasing power over time. At 2% annual inflation, $3,000/month today has roughly $1,800/month of today's buying power 25 years later. Some insurers offer COLA (cost-of-living adjustment) riders, but these increase the premium cost meaningfully and are worth modeling before adding.

What a Fee-Only Advisor Helps You Do

Annuity sales are among the most commission-heavy transactions in personal finance. A broker selling a variable annuity can earn 5–8% of the premium; even a simple SPIA carries an embedded commission in most channels. A fee-only advisor earns nothing from annuity sales and has no incentive to recommend one product over another, or an annuity over a bond ladder or higher equity allocation.

A fee-only advisor with couples-planning experience can:

• Model your household's actual income gap and determine whether an annuity meaningfully closes it
• Calculate the QLAC benefit for your specific IRA balances, expected RMD path, and IRMAA exposure
• Run the joint-and-survivor math for your specific ages, SS amounts, pension amounts, and health situations
• Compare annuity income against a bond ladder, dividend strategy, or higher equity exposure for the same capital outlay
• Help you evaluate insurer ratings and state guaranty fund limits before committing to a large premium
• Coordinate the annuity decision with your Roth conversion plan, IRMAA management, and estate strategy — all of which interact directly
