10.1 Annuity Payout Options and the Exclusion Ratio
Key Takeaways
- Life-contingent options pay while a life survives; straight life pays the highest income but guarantees nothing to a beneficiary.
- Period-certain options (fixed-period, fixed-amount) ignore life expectancy and pay from fund value and interest.
- The exclusion ratio = investment in the contract divided by expected return, and sets the tax-free fraction of each annuitized payment.
- Once cost basis is fully recovered, 100% of later payments are taxable; unrecovered basis at death is deductible.
- The exclusion ratio applies to annuitized income only — partial withdrawals use LIFO.
Annuity Payout Options and the Exclusion Ratio
An annuity is a contract that converts a sum of money into a stream of income. The exam separates the accumulation phase (money is paid in and grows tax-deferred) from the annuitization phase (the insurer pays income out). The moment the owner elects an income option and the contract begins paying is called annuitization.
The payout options below are settlement choices the annuitant (the measuring life) selects. They fall into two families: life-contingent options (payments tied to a life) and period-certain options (payments tied to a guaranteed number of payments, not a life).
Life-Contingent Payout Options
Life-contingent options pay as long as a named life lives. The insurer pools mortality risk, so these options usually pay the highest periodic income.
| Option | Pays | Refund on early death | Income level |
|---|---|---|---|
| Straight life (life only) | For the annuitant's life | None — insurer keeps the balance | Highest |
| Life with period certain | For life, but at least a set number of years | Remaining certain payments to beneficiary | Lower than straight life |
| Life with refund (cash/installment) | For life; guarantees premium is returned | Unrecovered cost basis to beneficiary | Lower |
| Joint and survivor | While either of two lives survives | Continues to survivor (often at 50%/66%/100%) | Lowest |
Exam trap: Straight life pays the most per period because it offers no death-benefit guarantee. If the annuitant dies after one payment, the insurer keeps the rest. Candidates confuse this with a "bad deal" — it is simply pure mortality pooling.
Period-Certain (Non-Life) Options
These options ignore life expectancy and pay a fixed schedule:
- Fixed-period option — equal payments over a stated number of years (for example, 10 years). Whoever is named receives any remaining payments if the annuitant dies before the term ends.
- Fixed-amount option — a chosen dollar amount per period until the fund plus interest is exhausted; the number of payments is whatever the fund supports.
- Lump sum (cash surrender) — the entire value paid at once; this is not technically annuitization and triggers different tax rules.
Because no mortality credit applies, period-certain income is calculated purely from the fund value, the interest rate, and the schedule. The two are mirror images: fixed-period locks the time and lets the payment float; fixed-amount locks the payment and lets the time float.
Choosing an Option: Scenario Reasoning
The exam often gives a fact pattern and asks which option fits a client's goal:
| Client goal | Best-fit option | Why |
|---|---|---|
| Maximize personal lifetime income, no heirs | Straight life | Highest payout; no guarantee needed |
| Lifetime income but protect a beneficiary for a minimum term | Life with period certain | Income for life, plus a guaranteed payout window |
| Be sure total premiums are returned | Life with refund | Guarantees recovery of cost basis |
| Provide income to a surviving spouse | Joint and survivor | Continues while either spouse lives |
| Bridge income for a fixed number of years (e.g., until Social Security starts) | Fixed-period | Defined term, then stops |
Exam trap: A pure life option pays more than any guaranteed option because the insurer assumes no obligation to pay a beneficiary. Adding any guarantee (period certain, refund, survivor) lowers the periodic payment. Candidates often pick the option with the most guarantees as "best" — the correct answer depends on the stated goal, not on which option is safest.
Which annuity payout option provides the highest periodic income but no guarantee to a beneficiary?
The Exclusion Ratio
When a non-qualified annuity (funded with after-tax dollars) is annuitized, each payment is part return of cost basis (tax-free) and part earnings (ordinary income). The exclusion ratio sets the tax-free fraction of every payment.
Formula
Exclusion Ratio = Investment in the Contract ÷ Expected Return
| Term | Meaning |
|---|---|
| Investment in the contract | After-tax premiums paid (cost basis) |
| Expected return | Periodic payment × expected number of payments (from IRS life-expectancy tables for life options) |
The ratio is multiplied by each payment to find the excluded (tax-free) portion. The remainder is taxable.
Worked Example
| Factor | Value |
|---|---|
| Cost basis (premiums paid) | $150,000 |
| Monthly income | $1,200 |
| Life expectancy at annuitization | 25 years = 300 months |
| Expected return | $1,200 × 300 = $360,000 |
| Exclusion ratio | $150,000 ÷ $360,000 = 41.67% |
Each $1,200 payment:
- Tax-free: $1,200 × 41.67% = $500.04
- Taxable: $1,200 × 58.33% = $699.96
After Cost Basis Is Recovered
The exclusion ratio applies only until total tax-free amounts equal the cost basis. For a life annuitant who outlives the table, once the full $150,000 is recovered, 100% of every later payment is taxable. Conversely, if the annuitant dies before recovering the basis, the unrecovered investment is deductible on the final return.
Exam trap: The exclusion ratio applies to annuitized payments only. Random partial withdrawals during accumulation are taxed under LIFO (earnings first), not the exclusion ratio. Mixing these up is the most common annuity-tax error.
A non-qualified annuity has a $100,000 cost basis and an expected return of $250,000. What portion of each annuitized payment is taxable?
