10.1 Annuity Payout Options and the Exclusion Ratio
Key Takeaways
- Life-only pays the most per dollar because nothing is guaranteed to a beneficiary; joint-and-survivor pays the least because it has the longest expected payout.
- Exclusion ratio = investment in the contract (cost basis) ÷ expected return; it sets the tax-free share of each annuitized payment.
- Once the full cost basis is recovered, 100% of later annuity payments become taxable; early death allows a deduction for unrecovered basis.
- Immediate annuities pay within one period of a single premium; deferred annuities accumulate first and provide the tax-deferral benefit.
- Variable annuities use a separate account, shift investment risk to the owner, and require a securities registration in addition to a life license.
Annuity Payout Options and the Exclusion Ratio
An annuity is a contract issued by a life insurer that systematically liquidates a sum of money. The accumulation period is when the annuitant (the measuring life) pays in and the contract grows tax-deferred. The annuitization phase (also called the payout or liquidation period) is when the insurer converts the accumulated value into a stream of income. The exam tests how each payout option behaves and how much of each check is taxable.
The annuitant is the person whose life expectancy determines payments. The owner holds the contractual rights and may differ from the annuitant. The beneficiary receives any remaining value if the annuitant dies. Do not confuse these three roles on exam scenarios.
The settlement (payout) options
Payout options trade certainty of income amount against certainty that a beneficiary will receive something. The more the insurer guarantees to a survivor, the smaller each monthly check, because the insurer carries more risk.
| Payout option | Who is paid / for how long | Income size | Death-of-annuitant result |
|---|---|---|---|
| Life only (straight life) | Annuitant for life only | Largest per-dollar income | Payments stop; no refund to beneficiary |
| Life with period certain | Life, but guaranteed minimum years (e.g., 10) | Smaller than straight life | Beneficiary gets remaining certain-period payments |
| Life with refund (cash/installment) | Life, but at least premium is returned | Smaller | Beneficiary gets unrecovered principal |
| Joint life | Until the first of two annuitants dies | Larger than joint-and-survivor | Stops at first death |
| Joint and survivor | Until the last of two annuitants dies | Smallest (longest expected payout) | Survivor continues (often 100%, 2/3, or 1/2) |
A common trap: life only pays the most per dollar precisely because it guarantees nothing to a beneficiary. A retiree wanting maximum income with no heir concern picks it; one protecting a spouse picks joint and survivor.
Annuity classifications by payout timing
- Immediate annuity — purchased with a single premium and begins payout within one payment interval (within 12 months). Often called a Single Premium Immediate Annuity (SPIA).
- Deferred annuity — payout begins more than one period in the future; funded by single or periodic premiums. Only deferred annuities have a meaningful accumulation period for tax deferral.
Annuity classifications by underlying investment
- Fixed annuity — guaranteed minimum interest rate; the insurer bears investment risk; payments are level dollar amounts. Backed by the insurer's general account.
- Variable annuity — premiums go into a separate account of sub-accounts; the annuitant bears investment risk; income varies. Requires both a life and a securities (FINRA) registration because it is a security.
- Indexed (equity-indexed) annuity — a fixed annuity whose interest is tied to an index (e.g., S&P 500) subject to a participation rate, cap, and guaranteed floor (often 0% to 3%).
The exclusion ratio (taxation of annuitized payments)
When a nonqualified annuity is annuitized, each payment is part return of principal (the cost basis you already paid tax on) and part taxable interest. The exclusion ratio is the fraction of each payment excluded from income tax:
Exclusion ratio = Investment in the contract (cost basis) ÷ Expected return
Expected return = monthly (or annual) payment × number of payments expected over the annuitant's life expectancy (from IRS tables).
Worked example: Maria pays $100,000 into a nonqualified annuity (her basis). At annuitization she receives $600/month, and her IRS life expectancy is 20 years (240 months). Expected return = $600 × 240 = $144,000.
- Exclusion ratio = $100,000 ÷ $144,000 = 0.6944 (69.44%).
- Tax-free portion each month = $600 × 0.6944 = $416.67.
- Taxable portion each month = $600 − $416.67 = $183.33.
Key trap: Once Maria has recovered her entire $100,000 basis (after the expected 240 payments), the exclusion ratio no longer applies—100% of every later payment is taxable. Conversely, if she dies early before recovering basis, the unrecovered amount is deductible on her final return.
A retiree buys a $90,000 nonqualified immediate annuity paying $500/month with a life expectancy of 300 months. What portion of each $500 payment is excluded from income tax?
A married couple wants annuity income that continues as long as either spouse is alive, accepting a smaller monthly check in exchange. Which payout option fits?
Computing the Exclusion Ratio
When a nonqualified annuity is annuitized, each payment blends a tax-free return of basis with taxable gain. The split is the exclusion ratio:
Exclusion ratio = Investment in the contract ÷ Expected return
- Worked example: Basis (premiums paid) = $100,000. Expected return over the payout (monthly payment × months of life expectancy) = $200,000. Exclusion ratio = 100,000 ÷ 200,000 = 50%. So 50% of each payment is tax-free; 50% is taxable ordinary income.
- If the annuitant outlives the table life expectancy and fully recovers basis, all later payments become 100% taxable.
- If the annuitant dies early before recovering basis, the unrecovered amount may be a deduction on the final return.
Choosing a Payout Option
Payout (settlement) options trade payment size against guarantees:
| Option | Largest payment? | Heirs protected? |
|---|---|---|
| Straight life (life only) | Yes — highest | No — stops at death |
| Life with period certain | Lower | Yes — to end of certain period |
| Life with refund (cash/installment) | Lower | Yes — at least basis returned |
| Joint and survivor | Lowest | Yes — continues to survivor |
Straight life pays the most because the insurer keeps any unpaid balance at death (no death-benefit guarantee). The exam frequently asks which option a single retiree with no dependents seeking maximum income should pick — the answer is straight life income.
