What Is a Single Premium Immediate Annuity (SPIA)?

A Single Premium Immediate Annuity (SPIA) is a financial contract purchased from an insurance company, designed to convert a lump sum of money into a guaranteed stream of regular income payments. This product serves as a tool for individuals seeking financial predictability during their retirement years by providing a dependable cash flow. It involves a single upfront payment in exchange for these ongoing distributions.

Understanding a Single Premium Immediate Annuity (SPIA)

In return for a one-time, lump-sum payment to an insurance company, a Single Premium Immediate Annuity (SPIA) provides immediate, regular income distributions that begin shortly after purchase. “Immediate” in this context typically means payments commence within one year, often as soon as a month or quarter after the contract is established.

The specific amount of each payment is fixed at the time the SPIA is purchased, eliminating uncertainty about future income levels. This payment amount is determined by several factors, including the size of the initial premium, the annuitant’s age, and prevailing interest rates at the time of purchase. As an individual ages, the expected payout period shortens, which can lead to higher individual payments for the same premium amount. This arrangement transfers the risk of outliving one’s savings, known as longevity risk, from the individual to the insurance company.

Once the lump sum is paid, the insurance company assumes responsibility for providing the guaranteed income stream. This removes the need for the individual to manage the underlying assets, providing a stable financial foundation for retirement. SPIAs are often considered a personal pension because they replicate the guaranteed income stream that traditional employer-sponsored pensions once provided.

Key Payout Options and Features

SPIAs offer various structures for income payments, allowing individuals to tailor the annuity to their specific financial planning needs. Each option presents a different balance between payment size, duration, and beneficiary provisions. The choice of payout option influences the amount of each payment and how long the income stream will last.

One common payout option is “Life Only,” which provides income payments for the entire duration of the annuitant’s life, with payments ceasing upon their death. This option typically offers the highest regular payments because the insurance company’s obligation ends with the annuitant’s passing. Another popular choice is “Life with Period Certain,” where payments are guaranteed for the annuitant’s lifetime but also for a specified minimum number of years, such as 10 or 20. If the annuitant dies before the period certain expires, the remaining payments are made to a designated beneficiary.

A “Joint and Survivor” annuity is designed to provide income for two lives, typically a couple. Payments continue for the primary annuitant’s life and then, often at a reduced amount, for the life of the surviving annuitant after the first person’s death. This option ensures that a surviving spouse or partner continues to receive income. Additionally, an “Inflation-Adjusted” option allows payments to increase annually by a fixed percentage or in line with an inflation index. While this option typically starts with lower initial payments, it helps to preserve purchasing power over time, protecting against the erosion caused by rising costs.

Taxation of SPIA Payments

The taxation of income received from a Single Premium Immediate Annuity depends on whether the initial lump sum was funded with after-tax or pre-tax money. For SPIAs purchased with after-tax funds, each payment is considered to consist of two parts: a return of the original principal and taxable earnings or interest. The portion representing the return of principal is not taxed again, as taxes were already paid on those funds before they were invested in the annuity.

The Internal Revenue Service (IRS) utilizes an “exclusion ratio” to determine the non-taxable portion of each payment from a non-qualified annuity. This ratio is calculated by dividing the initial investment in the contract by the total expected return over the annuity’s payment period. For example, if the exclusion ratio is 70%, then 70% of each payment is considered a tax-free return of principal, while the remaining 30% is taxable ordinary income. Once the total amount of the original investment has been returned to the annuitant through these tax-free portions, all subsequent payments become fully taxable as ordinary income.

Conversely, if a SPIA is purchased with pre-tax money, such as funds rolled over from a traditional Individual Retirement Account (IRA) or 401(k) plan, the entire amount of each payment received is subject to ordinary income tax. This is because neither the contributions nor any earnings within these qualified retirement plans have been taxed previously.

Important Considerations

Once a SPIA contract is purchased, the lump sum payment becomes irrevocable, meaning the original principal cannot be readily accessed for other purposes. This design provides guaranteed income but significantly reduces the liquidity of the invested funds.

The fixed nature of payments from many SPIAs means they do not typically adjust for inflation unless an inflation-adjusted rider is chosen at purchase. Over time, if inflation rises, the purchasing power of fixed payments can diminish. Consistent inflation can gradually erode the real value of a fixed income stream over decades.

Furthermore, once funds are converted into a SPIA, the principal does not participate in market gains or investment growth. The benefit is a predictable income stream, rather than asset appreciation. This means the funds are no longer available for investment in other assets that might offer higher returns.
