Most people with large IRAs spend their 60s thinking about how to grow the balance. A QLAC does the opposite on purpose. It lets you move a portion of your IRA into a structure that deliberately delays income — and in doing so, shrinks your future required minimum distributions, potentially reduces how much of your Social Security gets taxed, and guarantees you can’t outlive at least part of your income. That’s a lot of work for one product. Whether it’s the right tool depends entirely on your specific situation.
Let me walk through what a QLAC actually is, what the math looks like for someone with $420,000 in an IRA at 68, and when it makes sense to buy one versus skip it entirely.
What a QLAC Is, Without the Jargon
QLAC stands for Qualified Longevity Annuity Contract. The name is a mouthful, but the concept is straightforward: you move a portion of your IRA into an annuity that won’t start paying you until a future date you select — somewhere between age 72 and 85. Most people buying them set the start date around 80 or 85.
Two things happen when you do this. First, the money you put into the QLAC is excluded from your IRA balance for required minimum distribution calculations. That’s the IRS blessing that makes QLACs useful: it’s the only legal way to delay RMDs on a specific chunk of your retirement account. Second, when the deferred income eventually starts, you receive guaranteed monthly payments for the rest of your life — regardless of market conditions, regardless of how long you live.
Think of it as longevity insurance. You’re buying a guarantee against the financial consequences of living a very long time.
Congress raised the maximum QLAC purchase limit to $200,000 under the SECURE 2.0 legislation, and removed the old 25%-of-balance cap. So a 68-year-old with $420,000 in a traditional IRA can put up to $200,000 into a QLAC — nearly half the balance. In practice, most financial planners suggest starting with a smaller amount to see how the math works for your specific situation before committing the maximum.
The RMD Math for a $420,000 IRA
Required minimum distributions start at age 73 under current law. The IRS uses its Uniform Lifetime Table to calculate the minimum you must withdraw each year, with the divisor declining as you age — meaning a larger and larger percentage of your account gets forced into income annually.
At 73, the Uniform Lifetime Table divisor is roughly 26.5. On a $420,000 IRA, that’s a required distribution of approximately $15,849 in year one — and that’s before accounting for any growth between now and then. If the account grows to $480,000 by 73, the RMD is nearly $18,100.
Now put $105,000 into a QLAC at 68 (roughly 25% of the current balance, a natural first-tier commitment). That money is immediately excluded from your RMD calculation base. Your RMD base drops from $420,000 to $315,000 today — and the QLAC premium doesn’t grow inside the RMD calculation during the deferral period. When the remaining $315,000 grows to $360,000 by age 73, your RMD is approximately $13,585 instead of $18,100.
That’s roughly $4,500 less in taxable income per year. On its own, $4,500 might sound modest. But it isn’t when you trace where that income lands.
Why Smaller RMDs Can Have Outsized Tax Effects
RMDs pile directly onto your adjusted gross income. For most retirees without a pension, ordinary income in the $60,000–$90,000 range is where things get complicated — Social Security taxation increases as income rises, and Medicare IRMAA surcharges kick in at specific income thresholds.
Social Security benefits become partially taxable once your "combined income" (AGI plus nontaxable interest plus half your SS benefit) exceeds $25,000 single / $32,000 married. Up to 85% of your benefits become taxable at higher thresholds. Reducing your RMD by $4,500 per year can keep more of your Social Security outside the taxable bucket — a real dollar effect that compounds annually for as long as you’re taking RMDs. Our breakdown of how much Social Security becomes taxable with a large IRA and $24,000 in benefits shows exactly how this calculation works in practice.
Medicare IRMAA surcharges add another layer. If your modified AGI exceeds specific thresholds — currently starting around $103,000 for single filers — your Part B and Part D premiums increase significantly. The surcharges step up in tiers, and a $4,500 income reduction can be the difference between staying in the base tier and crossing into the next one. That’s worth hundreds of dollars per year in Medicare premium savings. How Medicare Part B costs change with income covers those surcharge tiers in detail.
Add the income tax savings, the Social Security tax reduction, and the Medicare premium savings together, and the annual benefit of a reduced RMD often exceeds what a simple arithmetic comparison of the RMD numbers suggests.
The Break-Even Question: Are You Betting on Living a Long Time?
Yes. That’s honest. A QLAC is a bet that you’ll live long enough for the guaranteed income stream to exceed what you gave up in flexibility and growth potential.
For a 68-year-old who puts $105,000 into a QLAC with payments starting at 85, typical payout rates from major insurers currently run somewhere in the range of $1,800–$2,400 per month for a male, somewhat less for a female (due to longer life expectancy), and less still for joint-life coverage that continues for a surviving spouse. Rates vary meaningfully by insurer and market conditions — always get multiple quotes.
At $2,000 per month, that’s $24,000 per year starting at 85. The $105,000 premium is recovered in roughly four and a half years of payments — by age 89 or 90. Every month after that is pure net benefit. If you reach 95, you’ve collected $240,000 from a $105,000 investment. If you die at 83, before payments begin, the story is different.
Most QLACs include a return-of-premium death benefit option: if you die before payments start, your beneficiaries receive the premium back. The tradeoff is a lower monthly payout once income begins — typically 10–20% less. Whether you want that rider depends on how much your heirs factor into your decision-making.
When I Think About This From a Risk Standpoint
Spending 30 years at the National Weather Service taught me something that applies directly here: the scenario you most need to plan for isn’t the average outcome — it’s the tail. Most people will retire, spend 20 years enjoying it, and die before their money runs out. The financial plan that works for that average person is straightforward. But some people will live to 95, 97, or 100. And they will watch their investments depleted by a 20-year bear market in their 80s, or face medical costs their portfolio wasn’t sized for.
A QLAC doesn’t make the average case better. It makes the tail survivable. That’s not a criticism — that’s exactly what insurance is supposed to do. The question is whether your specific risk exposure warrants the cost of that coverage.
If you have a pension, a spouse’s survivor benefit, and Social Security covering your essential expenses, you probably don’t need a QLAC. Your longevity risk is already mostly covered. The IRA is discretionary spending money, and flexibility matters more than insurance.
If you have no pension, your Social Security barely covers necessities, and a large IRA is your primary asset — a QLAC on a portion of that IRA starts looking like responsible risk management. It’s the floor you’re building under the most vulnerable part of your plan.
Who Should Seriously Consider a QLAC
The QLAC fits best when several conditions overlap:
- You’re in good health and have reasonable family longevity — a 68-year-old with two parents who lived past 90 is a better QLAC candidate than someone with significant health challenges
- Your IRA balance is large enough that RMDs will create meaningful tax drag — generally $300,000 and above, though this varies by income situation
- You don’t have a pension or other guaranteed income stream covering your base expenses
- You’re willing to trade flexibility for certainty — the money in the QLAC is committed; you can’t undo it if circumstances change
- You’ve already considered other IRA tax-reduction strategies (Roth conversions, QCDs) and the QLAC fills a gap those don’t address
Roth conversions and QLACs address the RMD problem differently and aren’t mutually exclusive. Converting $50,000–$80,000 per year to a Roth between 65 and 72 reduces your future RMD base. A QLAC reduces it more directly. For a 68-year-old five years from RMDs, there’s still meaningful conversion capacity before the RMD clock starts — but if the conversion math doesn’t work cleanly, the QLAC offers a parallel path. How a market downturn can create a Roth conversion window covers the conversion angle in detail — it’s worth understanding both before choosing one over the other, or combining them.
Who Should Skip It
The QLAC is wrong for you if:
- Your health is poor — buying longevity insurance when longevity isn’t your likely risk is paying for coverage you won’t use
- You have significant assets outside the IRA — liquidity matters, and locking $100,000+ into an annuity structure makes sense only when the remaining portfolio can handle unexpected needs
- Your heirs are a central priority — QLACs are not efficient estate planning tools; the money largely stays with the insurance company if you die before or shortly after payments begin (even with a return-of-premium rider)
- Your RMDs won’t be large enough to create a tax problem — if your IRA at 73 will generate $8,000–$10,000 in RMDs and your total income is below the Social Security taxation and IRMAA thresholds, the problem a QLAC solves doesn’t exist for you
The Next Step: Get Actual Quotes
QLAC pricing varies more than most people expect. The same $105,000 premium can generate meaningfully different monthly income depending on the insurer, current interest rates, and whether you include joint-life coverage or a return-of-premium rider. Get at least three quotes before making any decision.
Websites like ImmediateAnnuities.com and Blueprint Income allow you to compare QLAC quotes from multiple insurers without committing. Start there to understand the realistic payout range for your age and premium amount. A fee-only fiduciary financial advisor who specializes in retirement income can model the specific tax savings against the payout structure for your income situation — worth the cost of a one-time consultation before committing six figures to any annuity product.
