How Income Annuities Work and What They Pay You

What an income annuity does

An income annuity is a contract with an insurance company where you give them a lump sum of money, and they promise to pay you a fixed amount every month (or quarter or year) for the rest of your life. You stop receiving payments when you die. The insurance company keeps whatever money is left.

The core trade-off is straightforward: you exchange a large amount of money today for predictable income later. Unlike a savings account or investment portfolio, you cannot access the principal once you hand it over. In exchange, you do not have to worry about running out of money or managing investments.

Income annuities are also called when ready annuities because the payments start within a year of purchase, usually within a few months. This is different from deferred annuities, which you buy now but do not draw from until later.

Key Takeaways

• You pay a lump sum to an insurance company and receive fixed monthly payments for life, with no access to the original money after purchase.
• The monthly payment amount depends on your age, gender, how much you invest, current interest rates, and which payout option you choose.
• Income annuities provide certainty but offer no growth potential and no way to leave money to heirs unless you choose a joint or survivor option.
• The insurance company's financial strength matters because they must pay you for decades, so check their ratings before buying.
• You can purchase an income annuity with money from an IRA, a 401(k) rollover, or taxable savings, and the tax treatment differs for each source.

How the payment amount is calculated

The insurance company uses four main factors to set your monthly payment. First is your age at purchase—the older you are, the higher your monthly payment, because the company expects to pay you for fewer years. Second is your gender; women typically receive lower monthly payments because they have longer life expectancy on average.

Third is the amount you invest. A $100,000 investment produces a different monthly payment than a $500,000 investment. Fourth is the current interest rate environment. When interest rates are higher, insurance companies can promise higher monthly payments because they earn more on the money you give them.

You can also choose different payout structures that change the payment amount. A life-only annuity pays the most per month but stops when you die—your heirs receive nothing. A life with period certain annuity guarantees payments for a set number of years (often 10 or 20) even if you die, then continues for life. A joint and survivor annuity continues paying your spouse or designated beneficiary after you die, usually at a reduced rate. Each option lowers the monthly payment because the insurance company may pay for longer.

What happens to your money after you buy

Once you sign the contract and transfer your money, you own an income stream, not an investment. The insurance company owns and invests the principal. You have no say in how it is invested, and you cannot withdraw the lump sum if you change your mind or face an emergency.

Some annuities include a free look period, usually 10 to 30 days, during which you can cancel and get your money back. After that window closes, the money is gone. A few income annuities allow you to take out a small percentage each year (sometimes 10 percent) without penalty, but this is uncommon and reduces your monthly payment.

Your monthly payment never changes. If inflation rises, your purchasing power falls, but your check stays the same. Some annuities offer a cost-of-living adjustment (COLA) that increases payments by a set percentage each year, but this option lowers your starting payment significantly.

Tax treatment depends on where the money comes from

If you buy an income annuity with money from a traditional IRA or a 401(k) rollover, the entire monthly payment is taxed as ordinary income in the year you receive it. The insurance company will send you a 1099-R form each January reporting the payments.

If you buy with after-tax money from a savings account or brokerage, only part of each payment is taxed. The IRS uses an exclusion ratio to determine how much of your payment is a return of your own principal (not taxed) versus earnings (taxed). This calculation is complex, and the insurance company provides it on your 1099-R.

If you buy an annuity inside a Roth IRA, payments are tax-free as long as you follow Roth withdrawal rules. Consult a tax professional before purchasing to understand the specific tax outcome for your situation.

When income annuities make sense

Income annuities work best for people who want to convert a portion of their savings into may provide lifetime income and do not need access to that money. They are often used alongside Social Security to cover essential expenses like housing and utilities.

They can be useful if you have a large lump sum from an inheritance, a pension buyout, or a retirement account and want to remove the burden of managing investments. They also suit people who are uncomfortable with market risk or who live longer than average (since longevity increases the value of lifetime payments).

Income annuities are less suitable if you need liquidity, expect to live a short life due to health conditions, want to leave money to heirs, or believe you can earn better returns by investing the money yourself. They are also not a good fit if you cannot afford to lock up the money for decades.

Comparing income annuities to other options

An income annuity differs from a bond ladder, which you can build yourself by buying bonds that mature at different times. With bonds, you keep control and can sell if you need cash. With an annuity, you trade control for the insurance company's promise to pay you no matter how long you live.

It also differs from a dividend-paying stock portfolio, which can grow over time and pass to heirs. An annuity payment never grows, but it also never shrinks if the market falls. A dividend portfolio offers more upside and flexibility; an annuity offers more certainty.

Some people use a combination: they buy a small income annuity to cover essential expenses and invest the rest of their portfolio for growth and flexibility. This approach balances security with opportunity.

Checking the insurance company's strength

Because you depend on the insurance company to pay you for decades, its financial stability matters. Before buying, check the company's ratings from agencies like A.M. Best, Moody's, or Standard & Poor's. These ratings reflect the company's ability to pay claims. Look for ratings in the A range or higher.

You can also check your state's insurance commissioner's office for complaints or disciplinary actions against the company. The National Association of Insurance Commissioners (NAIC) maintains a database of complaints by company and state.

If an insurance company fails, your annuity is usually protected by your state's insurance guaranty fund, which covers claims up to a limit (often $250,000 per person per company). However, relying on this protection is not ideal, so choosing a financially strong company upfront is the better approach.

Frequently Asked Questions

Can I get my money back if I change my mind?

Most income annuities allow you to cancel within a free look period, usually 10 to 30 days, and receive a full refund. After that window closes, you cannot withdraw the principal. Some annuities allow small annual withdrawals (often 10 percent), but this is rare and reduces your monthly payment.

What if I die shortly after buying an income annuity?

With a life-only annuity, your heirs receive nothing—the insurance company keeps the remaining balance. If you choose a life with period certain or joint and survivor option, payments continue to your beneficiary or spouse for the may provide period or their lifetime. This protection costs you a lower monthly payment.

Do income annuities protect against inflation?

Standard income annuities do not adjust for inflation; your payment stays the same for life. Some annuities offer a cost-of-living adjustment (COLA) that increases payments annually, but this option significantly reduces your starting payment. You must choose this option at purchase; you cannot add it later.

Can I buy an income annuity with retirement account money?

Yes. You can purchase an income annuity with money from a traditional IRA, a 401(k) rollover, or a Roth IRA. The tax treatment differs: traditional and rollover money is taxed as ordinary income when paid out, while Roth payments are tax-free if you meet withdrawal rules. Some retirement plans have rules about annuity purchases, so check with your plan administrator first.

How do I compare quotes from different insurance companies?

Contact multiple insurance companies or use an annuity quote service to compare monthly payment amounts for the same investment, age, gender, and payout option. Payments vary by company and change daily with interest rates. Compare quotes from at least three companies and check each company's financial ratings before deciding.
