10.1 Annuity Payout Options and the Exclusion Ratio
Key Takeaways
- Life-contingent options pay based on the annuitant's life; adding guarantees (period certain, refund, joint and survivor) lowers the monthly payment.
- Pure life pays the most because the insurer keeps any balance at death; non-life options (fixed period, fixed amount) can exhaust the fund.
- Exclusion Ratio = Investment in the Contract / Expected Return, and it applies only to annuitized payments, not surrenders.
- Once the full cost basis is recovered tax-free, 100% of later payments become taxable.
- If the annuitant dies before recovering basis, the unrecovered amount may be deducted on the final return.
From Accumulation to Income
Every deferred annuity has two phases. The accumulation phase is when money goes in and earns interest. The annuitization phase (also called the payout phase or liquidation phase) is when the insurer converts the accumulated value into a stream of income payments. The contract owner triggers payout by choosing a settlement option (also called an annuity payout option).
The owner can also simply take surrenders or partial withdrawals instead of annuitizing. The distinction matters for taxes (covered in 10.3): annuitized payments use the exclusion ratio, while withdrawals do not.
Life-Contingent Payout Options
Life-contingent options base payments on how long one or more annuitants live. The insurer pools risk across many contracts, so longevity risk is shifted to the insurer.
| Option | How it works | Trap to remember |
|---|---|---|
| Pure life / life only / straight life | Pays for the annuitant's lifetime; stops at death | Highest monthly income, but if the annuitant dies early the insurer keeps the balance |
| Life with period certain | Pays for life, but guarantees a minimum number of years (e.g., 10 or 20) | If annuitant dies during the certain period, a beneficiary collects the rest |
| Life with refund (installment or cash) | Pays for life; if annuitant dies before recovering the principal, the balance goes to a beneficiary | Guarantees the investment is returned, not lifetime payments |
| Joint life | Pays until the first of two annuitants dies | Income stops on first death |
| Joint and survivor (J&S) | Pays until the last annuitant dies; survivor may get 100%, 66 2/3%, or 50% | Lowest monthly income because it covers two lives |
Rule of thumb: the more guarantees attached, the lower the monthly payment, because the insurer takes on less mortality risk.
Non-Life-Contingent (Period) Options
These do not depend on anyone living. The insurer pays out a fixed value regardless of death.
- Fixed period (period certain): The insurer pays for a set number of years (e.g., 15 years). Whatever is left at death goes to a beneficiary.
- Fixed amount: The owner picks a dollar amount per period (e.g., $1,000/month); payments continue until the fund plus interest is exhausted.
- Lump sum / cash surrender: The entire value is paid at once. This is not annuitization, so the exclusion ratio does not apply.
Exam trap: Only options that involve the annuitant's life create true longevity protection. Period-certain and fixed-amount options can run out of money.
A stand-alone annuity certain (no life contingency) is sometimes sold to bridge a fixed need - for example, paying income only until Social Security begins. Because nothing depends on survival, the insurer simply schedules the fund plus interest over the chosen period or amount. The owner trades away longevity protection for certainty of total dollars paid.
The Exclusion Ratio
When an annuity is annuitized, each payment blends two parts: a tax-free return of the cost basis (the after-tax money the owner already paid in) and a taxable earnings portion. The exclusion ratio tells you what percentage of each payment is excluded from tax.
Exclusion Ratio = Investment in the Contract / Expected Return
- Investment in the contract = total after-tax premiums paid (the cost basis).
- Expected return = the periodic payment x the expected number of payments (based on IRS life-expectancy tables for a life annuity, or the guaranteed number of payments for a period certain).
Worked Exclusion-Ratio Example
A man pays $150,000 into a non-qualified annuity. At annuitization he is set to receive $1,200 per month, and the IRS table gives him a life expectancy of 25 years (300 months).
| Step | Figure |
|---|---|
| Investment in contract (basis) | $150,000 |
| Monthly payment | $1,200 |
| Expected payments | 300 |
| Expected return | $1,200 x 300 = $360,000 |
| Exclusion ratio | $150,000 / $360,000 = 41.67% |
| Tax-free per payment | $1,200 x 41.67% = $500 |
| Taxable per payment | $1,200 - $500 = $700 |
Critical rule: Once the annuitant has recovered the full $150,000 basis tax-free (i.e., lives past the table life expectancy), 100% of every later payment becomes taxable. Conversely, if the annuitant dies early and has not recovered the full basis, the unrecovered amount may be deducted on the final return.
A pure life annuity (life only) pays the HIGHEST monthly income compared with other life-contingent options primarily because:
An annuitant's investment in the contract is $100,000 and the expected return is $250,000. If each annuity payment is $1,000, how much of each payment is excluded from income tax?
Worked Exclusion-Ratio Example
The exclusion ratio determines how much of each annuity payment is tax-free return of principal. It equals the investment in the contract divided by the expected return. Example: a $100,000 nonqualified annuity (after-tax basis) pays $700/month for a life expectancy of 200 months, so expected return = $700 x 200 = $140,000. Exclusion ratio = $100,000 / $140,000 = 71.4%. Of each $700 payment, $500 is tax-free and $200 is taxable interest. Once total basis is fully recovered, all further payments are fully taxable.
Payout Options Mirror Life Settlement Options
Annuity payout (annuitization) options parallel life settlement options. Life only (straight life) pays the most but stops at death. Life with period certain guarantees payments for a minimum number of years. Life with refund (cash or installment) returns unpaid principal to a beneficiary. Joint and survivor continues to a second annuitant. Period certain and fixed-amount options ignore lifespan entirely. As with life insurance, more guarantees mean smaller checks.
A nonqualified annuity has a $90,000 cost basis and an expected return of $150,000. What portion of each payment is excluded from taxable income?
