An immediate annuity works like this: you give an insurance company a single lump sum, and in return the insurer sends you a guaranteed payment on a set schedule — usually starting within 30 days and continuing for the rest of your life or for a fixed number of years, depending on the option you pick. Most carriers require a minimum premium somewhere between $25,000 and $100,000. The payment amount is fixed at purchase and does not move with interest rates or market performance afterward. In exchange for that predictability, you generally give up access to the lump sum once a short cancellation window closes.
Where Your Money Goes and Why the Payments Can Be Larger Than a Drawdown
Your premium goes into the insurance company’s general account alongside premiums from thousands of other annuitants. The insurer invests that pool conservatively, mostly in bonds and similar fixed-income assets, and pays everyone from the returns. State insurance departments regulate the reserves carriers must hold against those obligations.
What lets an immediate annuity pay out more than you could safely withdraw from a personal savings account is called mortality credits. The insurer sets payments based on the average life expectancy of the pool. Some annuitants die earlier than expected, and the money they don’t collect is redistributed to those who live longer. The longer you survive, the more you benefit from the pooling. Your own check stays the same regardless of what happens to interest rates or the insurer’s investments after your contract begins.
Payout Options That Set the Size of Your Check
The structure you choose at purchase is permanent, and it drives both how much you receive each month and what, if anything, your heirs get.
Life-Only
A life-only annuity pays the highest amount for a given premium because the insurer’s obligation ends when you die. Pass away six months in, and the remaining balance stays with the company. It fits healthy buyers without dependents who want maximum income and accept that heirs may receive nothing.
Joint and Survivor
A joint-and-survivor annuity covers two lives, usually spouses, and keeps paying as long as either is alive. Monthly payments are lower than life-only for the same premium because the expected payout period is longer. Some contracts drop the payment 25% to 50% after the first death; others continue at the full amount. That difference can reshape a surviving spouse’s budget, so confirm which version you’re buying.
Period Certain
A period-certain option guarantees payments for a set number of years, commonly 10 or 20. Die before the period ends and your beneficiary collects the remaining payments; outlive the period and payments stop. A life-with-period-certain variant guarantees payments for the longer of your life or the fixed term.
Refund Provisions
Two refund structures ensure heirs recover at least what you paid in. A cash refund pays beneficiaries the unused portion of your premium as a lump sum at your death. An installment refund keeps sending them the same monthly payment you were receiving until the full premium has been paid out. Cash refund produces slightly lower monthly income because the insurer has to be ready to cut one large check.
How the Payments Are Taxed
Every payment contains two pieces: a return of the money you put in, and earnings. How the IRS taxes them depends on whether you funded the contract with after-tax or pre-tax dollars.
After-Tax (Non-Qualified) Money
If you bought the annuity with money from a savings or brokerage account, the IRS applies an exclusion ratio. It compares your investment in the contract to the total return expected over your lifetime; the principal portion of each payment comes back tax-free, and the earnings portion is taxed as ordinary income.1Office of the Law Revision Counsel. 26 USC 72 – Annuities; Certain Proceeds of Endowment and Life Insurance Contracts Once you’ve recovered your full investment, every dollar after that is fully taxable.
Pre-Tax (Qualified) Money
If the premium came from a 401(k), traditional IRA, or similar retirement account, you never paid tax on that money. Every dollar of every payment is ordinary income, and there is no exclusion ratio because there is no after-tax basis to recover. Qualified annuity payments use the Simplified Method; non-qualified use the General Rule.2Internal Revenue Service. Publication 575 – Pension and Annuity Income
The Age 59½ Penalty
The 10% additional tax that normally hits annuity earnings taken before age 59½ does not apply to immediate annuities. Section 72(q) of the Internal Revenue Code specifically exempts immediate annuity contracts from that surcharge.1Office of the Law Revision Counsel. 26 USC 72 – Annuities; Certain Proceeds of Endowment and Life Insurance Contracts A 55-year-old buying with non-qualified funds will not owe the penalty. If you’re rolling from a retirement account before 59½, the original account’s early-distribution rules can still apply, so check with a tax professional before you move the money.
How You Fund the Contract
The simplest funding route is a check or wire from a bank or brokerage account. That’s non-qualified money, and the exclusion ratio applies.
Rolling from a 401(k) or traditional IRA into an immediate annuity is also common. A direct rollover is not itself taxable, but the annuity becomes a qualified contract and every payment is fully taxable as ordinary income.
If you already own an annuity or life insurance policy, a 1035 exchange lets you move that value into an immediate annuity without triggering a tax bill. The statute allows tax-free exchanges from annuity to annuity, or from life insurance to annuity, with cost basis carrying over.3Office of the Law Revision Counsel. 26 USC 1035 – Certain Exchanges of Insurance Policies The transfer has to go directly between insurers; if the money passes through your hands, the IRS treats it as a distribution.
Applying, the Free-Look Window, and First Payment
The application asks for your Social Security number and proof of your date of birth (birth certificate, passport, or driver’s license), because age drives the actuarial calculation. You’ll provide bank routing and account numbers for electronic deposits, and your tax withholding preferences. Expect detailed questions about your income, other assets, and objectives; state best-interest rules require the agent to document why the product fits your situation and to disclose their compensation.
When the physical contract arrives, a free-look window opens. Depending on your state, it runs roughly 10 to 30 days, and during that time you can cancel and get your full premium back. Once it closes, the contract is generally irrevocable. Read the contract inside that window, not after.
The first payment usually arrives within 30 days of the effective date, though some contracts allow the start date to be pushed out up to a year. The schedule you chose — monthly, quarterly, semi-annually, or annually — then continues for the life of the contract.
What You Give Up: Liquidity
Once the free-look period expires, an immediate annuity is generally irrevocable. There is no surrender value. Your money comes back only through the scheduled payments.
Some contracts include a commutation provision, a rider that lets you exchange a portion of the remaining guaranteed payments for a present-day lump sum.4Insurance Compact. Individual Immediate Non-Variable Annuity Contract Standards It’s typically available only on period-certain contracts, not life-only, and using it reduces future income proportionally. The insurer may also reserve the right to defer that payout for up to six months. Commutation isn’t standard on every contract, so if liquidity matters, ask before signing and get the terms in writing.
The practical implication is that an immediate annuity should cover baseline living costs, not absorb your entire retirement savings. Keep other assets liquid for emergencies, medical costs, and large one-time expenses.
What You Give Up: Purchasing Power
A payment that feels adequate at 65 buys less at 80. Some carriers offer a cost-of-living adjustment rider that raises the payment each year by a fixed percentage, commonly 1% to 5% compounded.5Nationwide. What Is an Immediate Annuity Your starting check will be noticeably lower than a flat annuity of the same premium, because the insurer has to fund those rising payments over decades. For someone in good health who might live to 90, the compounding can eventually push payments above the flat alternative. For someone with health concerns, the lower start may never catch up.
If the Insurance Company Fails
Every state runs a guaranty association that steps in when a licensed insurer becomes insolvent. Coverage is funded by assessments on other insurers in the state and is capped by statute. All 50 states provide at least $250,000 in annuity coverage per person per insurer, and some states offer more, particularly for annuities already in payout status.6NOLHGA. The Nation’s Safety Net 2024-2025 For large premiums, spreading the purchase across two or more highly rated insurers keeps you inside guaranty limits at each one. Check your state’s specific figures, since a few cap coverage below the present value of a large annuity or limit the protected interest rate.
A Note on Medicaid Planning
An ordinary immediate annuity purchase does not automatically qualify under Medicaid rules. Under the Deficit Reduction Act of 2005, the purchase can be treated as a transfer for less than fair market value — triggering a penalty period — unless the annuity is irrevocable, non-assignable, actuarially sound under Social Security Administration life expectancy tables, structured to pay equal amounts with no deferrals or balloon payments, and names the state Medicaid program as remainder beneficiary for at least the amount of benefits paid. Rules also vary by state. If Medicaid eligibility is your reason for buying, work with an elder law attorney; a stock immediate annuity purchased without those specific features can disqualify you for months or years.
