A single premium immediate annuity, usually shortened to SPIA, is a contract you buy with one lump-sum payment in exchange for guaranteed income that starts almost right away, typically within about 30 days. A 65-year-old putting $100,000 into a life-only contract in 2026 can expect roughly $7,500 to $7,800 per year, depending on gender, insurer, and the payout structure chosen. The appeal is pension-like income you cannot outlive. The catch is that once a short cancellation window closes, the money belongs to the insurance company, and you generally cannot get it back.
How a SPIA Works
You hand an insurance company a single premium, and the company begins sending you income checks. That one payment is the only contribution the contract allows, which is what makes it “single premium.” Deferred annuities let you contribute over years and delay payouts; a SPIA exists purely to convert savings into income now.
The insurer can promise lifetime payments because of mortality pooling. Your premium is combined with premiums from thousands of other annuitants, and people who die earlier effectively subsidize those who live longer. That math is what lets the company guarantee income no matter how long any individual lives. State insurance departments require carriers to hold capital reserves behind these promises, and independent rating agencies evaluate whether each company can meet them.
What Determines Your Payment
Four things drive the size of your check: your age, your gender, prevailing interest rates, and the premium you deposit.
Age matters most. The older you are when you buy, the higher each payment, because the insurer expects to make fewer total payments. A 75-year-old will receive noticeably more per month than a 60-year-old depositing the same amount. Gender factors in too, because women statistically live longer than men. A male annuitant typically receives a slightly larger payment than a female of the same age.
Interest rates at the time of purchase lock in your payout for the life of the contract. When rates are high, insurers earn better yields on your premium and pass some of that through. Once you buy, your payment amount is fixed regardless of where rates go afterward. Premium size scales proportionally: $250,000 produces roughly 2.5 times the income of $100,000 under otherwise identical terms.
Insurer financial strength is the factor many buyers overlook. Five independent agencies rate insurance company stability, including A.M. Best, Fitch, Moody’s, and Standard & Poor’s, and their scales differ. An A+ from A.M. Best is that agency’s second-highest rating, while an A+ from S&P is its fifth-highest. Checking ratings from at least two agencies gives you a clearer picture of the company backing your income.
Payout Structure Options
The structure you choose sets both your monthly income and what happens to any remaining value when you die. Every option trades higher payments now against greater protection for beneficiaries.
- Life only pays the highest monthly amount. Payments stop entirely when you die, your heirs receive nothing from the contract, and the insurer keeps whatever principal remains. This fits when maximizing personal income is the priority and other assets are earmarked for heirs.
- Life with period certain guarantees payments for a minimum number of years, typically 10 or 20, even if you die early. If you pass away five years into a 20-year certain period, your beneficiary receives the remaining 15 years. If you outlive the guaranteed period, payments continue for life. Monthly income is lower than life only.
- Joint and survivor pays income until the second spouse dies. You choose in advance what percentage of the original payment continues to the survivor, commonly 50% or 100%. A 100% continuation means the survivor’s income doesn’t drop, but the starting payment is lower than a 50% election.
- Cash refund pays your beneficiaries a lump sum equal to any premium you didn’t recover in payments before dying. It protects against dying early and “losing” your deposit, at the cost of a lower monthly payment.
- Installment refund works the same as cash refund, except beneficiaries receive the remaining balance as ongoing monthly payments. Because the insurer holds the money longer, installment refund contracts usually pay slightly more per month than cash refund.
Each structure creates a different obligation for the insurer, and you cannot switch between them after the contract is finalized. The gap between the highest-paying option and the most protective option can be substantial, so this choice deserves real attention before you sign.
Why Irrevocability Is the Point to Pause On
Once the short cancellation window expires, a SPIA purchase is permanent. You cannot withdraw your lump sum, and in most contracts you cannot change the payout structure, the beneficiary, or any other term. The money belongs to the insurer, and your only ongoing right is to receive the promised payments.
After the contract is issued, you get a brief cancellation window called the free-look period, which runs at least 10 days in most states and can extend to 30 days depending on the contract and state rules.1Investor.gov. Variable Annuities – Free Look Period During that window, you can cancel and get a full refund. After it closes, the decision is final.
Some contracts include a commutation feature that lets you convert future payments into a reduced lump sum, but it isn’t standard, it carries significant financial penalties, and not every insurer offers it. A handful of contracts add hardship riders triggered by events like extended nursing home confinement, but these are narrow exceptions. Never put money into a SPIA that you might need for an emergency or a large expense.
Inflation and COLA Riders
A fixed payment that feels comfortable today will buy less a decade from now. At 3% annual inflation, a $2,000 monthly payment has the purchasing power of roughly $1,490 after 10 years and about $1,100 after 20 years. For a contract designed to last the rest of your life, that erosion is the biggest structural risk.
Some insurers offer a cost-of-living adjustment (COLA) rider that increases your payment by a fixed percentage each year, typically between 1% and 5%, compounding on the prior year’s payment. The catch is that funding those future increases requires a substantially lower starting payment. It can take a decade or more before the rising payments overtake what a level-payment contract would have delivered, and longer before cumulative income catches up. A COLA rider also doesn’t track actual inflation; you’re locking in a fixed escalation rate.
An alternative is to annuitize only part of your savings and keep the rest invested in assets that historically outpace inflation. That preserves guaranteed baseline income while leaving room for growth and liquidity.
How the Income Is Taxed
Tax treatment depends on where the money came from before it entered the annuity.
Qualified Money
If you fund the SPIA with money from a traditional IRA, 401(k), or similar tax-deferred retirement account, every dollar of every payment is ordinary income. You never paid income tax on those contributions or their growth, so the full amount is taxable when it comes out.2Internal Revenue Service. Topic No. 410, Pensions and Annuities
Non-Qualified Money
If you buy the SPIA with after-tax savings, only the earnings portion of each payment is taxable. The tax-free share is set by the exclusion ratio: your total investment divided by the expected total return over your lifetime.3Office of the Law Revision Counsel. 26 USC 72 – Annuities; Certain Proceeds of Endowment and Life Insurance Contracts For example, if you invest $100,000 and the insurer’s actuarial tables project $200,000 in total lifetime payments, your exclusion ratio is 50%. Half of every payment is a tax-free return of your own money, and the other half is taxable income. Once you’ve recovered your full original investment, every subsequent payment becomes fully taxable.4Internal Revenue Service. Publication 575, Pension and Annuity Income
Withholding
The insurer withholds federal income tax from your payments unless you instruct otherwise. You control the amount by filing IRS Form W-4P with the annuity company. If you submit no form, the insurer defaults to withholding as if you’re single with no adjustments, which usually means more tax withheld than necessary.5Internal Revenue Service. Form W-4P, Withholding Certificate for Periodic Pension or Annuity Payments You can elect zero withholding and handle estimated tax payments yourself, though that option isn’t available if your payments are delivered outside the United States.
Funding the Purchase
Insurance carriers require personal identification for all annuitants and beneficiaries, including Social Security numbers and dates of birth, along with your bank’s routing and account numbers for electronic deposits. The funding source has to be identified on the application because it determines whether the contract is qualified or non-qualified, which drives the tax treatment above.
- Direct transfer or rollover. Money moves from a retirement account (IRA, 401(k)) directly to the insurer, keeping the funds tax-deferred and avoiding an immediate tax hit.
- 1035 exchange. If you already own a life insurance policy or another annuity, federal law lets you swap it for a SPIA without recognizing gain on the old contract. The exchange must go directly between insurers; taking possession of the cash first turns it into a taxable event.6Office of the Law Revision Counsel. 26 USC 1035 – Certain Exchanges of Insurance Policies
- Cash payment. For non-qualified purchases, you fund by wire transfer or cashier’s check.
Most carriers set minimum premiums between $5,000 and $25,000, with maximums typically from $1 million to $3 million. Larger amounts often require prior approval from the insurer’s home office. Your first income payment usually arrives about one month after the contract’s effective date.
Who a SPIA Fits, and Who It Doesn’t
SPIAs solve a specific problem well: turning a pile of savings into income you cannot outlive. They fit retirees who have already covered their liquidity needs with other assets and want to lock in baseline income for essentials like housing, food, and insurance premiums. People without a pension often use a SPIA to build one, and the guaranteed nature of the payments can reduce the anxiety of drawing down a volatile portfolio.
They are a poor fit if you might need access to the money. Anyone without a separate emergency fund, anyone anticipating large near-term expenses, and anyone carrying high-rate debt should address those first. Younger investors with decades until retirement are almost always better served by contributing to tax-advantaged accounts where money can grow. And if a medical condition significantly shortens your life expectancy, a life-only SPIA likely pays out less than you put in.
Agents and brokers recommending annuities are subject to suitability standards adopted in most states, modeled on rules from the National Association of Insurance Commissioners. Before recommending a SPIA, the agent must gather information about your financial situation, insurance needs, and objectives, and must have a reasonable basis to believe the product benefits you.7National Association of Insurance Commissioners. Suitability in Annuity Transactions Model Regulation If no one asks about your overall finances before suggesting you buy, treat that as a red flag.
Medicaid Planning Is a Different Product
A standard SPIA is not a Medicaid planning tool. Married couples facing nursing home costs sometimes use a Medicaid-compliant annuity, which is a separate contract structure governed by strict federal rules: it must be irrevocable, non-transferable, paid in equal installments with no balloon or deferral, capped at the annuitant’s life expectancy per Social Security actuarial tables, and the state Medicaid agency must generally be named as a beneficiary to recover any medical assistance paid.8Office of the Law Revision Counsel. 42 USC 1396p – Liens, Adjustments and Recoveries, and Transfers of Assets Missing any of these requirements can turn the annuity purchase into a penalized asset transfer that delays Medicaid eligibility by months or years. If Medicaid qualification is your reason for buying, work with an elder law attorney rather than assuming an off-the-shelf SPIA will qualify.
If the Insurance Company Fails
Every state, plus the District of Columbia and Puerto Rico, operates a life and health insurance guaranty association that acts as a safety net when an insurer becomes insolvent.9National Organization of Life and Health Insurance Guaranty Associations. How You’re Protected If the company behind your SPIA goes under, the guaranty association in your state of residence steps in to continue coverage, transfer your policy to a stable insurer, or pay claims directly.
Coverage limits vary by state but typically fall between $250,000 and $500,000 per person for annuity benefits. Several states provide higher protection for annuities already in payout status; some apply a $300,000 limit for annuities making payments versus $250,000 for deferred annuities.10National Organization of Life and Health Insurance Guaranty Associations. The Nation’s Safety Net If your annuity’s value exceeds the guaranty limit, the excess becomes a claim against the failed insurer’s remaining assets and may pay only partially.
Guaranty coverage is a backstop, not a substitute for insurer quality. For large purchases, splitting the premium between two highly rated insurers so each contract sits within your state’s guaranty limit is a simple way to maximize protection. You can look up your state’s coverage through the National Organization of Life and Health Insurance Guaranty Associations (NOLHGA) or your state’s department of insurance.
