What Is an Income Annuity?

An income annuity is an annuity purchased mainly to turn a lump sum or accumulated value into a stream of payments. Those payments may begin immediately or later, depending on the contract structure, and may continue for a fixed period or for life. In retirement planning, the term usually refers to an annuity used to create dependable income rather than to build tax-deferred accumulation alone.

Key Takeaways

• An income annuity is built to provide payments, not just to accumulate value.
• Payments may begin right away or at a later date depending on the contract.
• Income annuities are often used in retirement to create more predictable cash flow.
• The payment structure can vary by contract, rider options, and beneficiary terms.
• An income annuity can reduce longevity risk, but it also involves tradeoffs around liquidity and flexibility.

How an Income Annuity Works

With an income annuity, the owner exchanges capital for a contractual payment stream. The insurer then uses the terms of the contract, including payout timing, age, and benefit structure, to determine how much income will be paid. Some contracts begin payments soon after purchase. Others defer the start date until later in retirement.

The defining feature is not the exact start date. It is the purpose of the contract. The annuity exists to generate income rather than simply to hold money for future tax deferral.

Why Retirees Use Income Annuities

Retirees use income annuities when they want part of their retirement plan to function more like a paycheck. A portfolio can provide growth and withdrawal flexibility, but it can also bring uncertainty around market performance and sustainable spending. An income annuity can offset some of that uncertainty by turning part of retirement savings into a contractual stream of income.

That can be especially attractive for households concerned about outliving assets or about maintaining a predictable baseline of spending money through retirement.

Income Annuity Versus Deferred Annuity

An income annuity is often contrasted with a Deferred Annuity. A deferred annuity is usually discussed first as an accumulation vehicle, even if it may later be annuitized or converted into income. An income annuity is designed from the start around payout rather than accumulation.

The distinction matters because the investor's objective changes how the annuity should be evaluated. If the goal is income, payout structure and reliability matter more than accumulation features.

Income Annuity Versus Immediate Annuity

An immediate annuity is one type of income annuity, but the two terms are not identical. An Immediate Annuity generally starts paying soon after purchase. An income annuity can include immediate structures, but it can also include contracts where income starts later. So immediate annuity is a narrower timing description, while income annuity is a broader functional description.

Why Income Annuities Matter in Retirement Planning

Income annuities matter because retirement planning is ultimately about converting assets into spending power. Building wealth is one part of the problem. Turning wealth into dependable income is another. Income annuities are one of the clearest products built for that second task.

They are often considered alongside Social Security, portfolio withdrawals, and strategies such as an Annuity Laddering Strategy. The right role depends on the retiree's need for certainty, liquidity, and legacy planning flexibility.

Example of an Income Annuity

Assume a retiree wants to cover core monthly expenses with more predictable income. The retiree uses part of a retirement portfolio to buy an annuity that begins scheduled payments according to the contract. Those payments then become one layer of the retirement-income plan alongside Social Security and other savings. That annuity is functioning as an income annuity because its central job is to generate spendable income.

Tradeoffs To Understand

An income annuity can reduce longevity risk and improve predictability, but it can also reduce flexibility. Once capital is committed to the contract, access to that money may be limited. The retiree also needs to evaluate insurer strength, inflation exposure, and how the annuity fits with the rest of the retirement plan.

That means income annuities are not inherently good or bad. They are tools with clear strengths and clear tradeoffs.

The Bottom Line

An income annuity is an annuity designed mainly to provide a stream of payments rather than simply accumulate value. It is commonly used in retirement planning to create more predictable income and reduce the risk of outliving assets. The core idea is simple: part of a retiree's capital is converted into a contractual income stream, with both stability benefits and flexibility costs.
