An annuity is, in a sense, the opposite of life insurance. Life insurance protects against dying too soon; an annuity protects against living too long by turning a sum of money into an income stream you can't outlive. This guide explains how annuities accumulate and pay out, the main product types (fixed, variable, indexed), when income starts (immediate vs. deferred), the payout options, surrender charges, suitability rules, and a high-level look at taxation.

What an annuity is and who's involved

An annuity is a contract with an insurer designed to provide income, usually for retirement. The parties:

• Owner – Buys the contract and holds the rights.
• Annuitant – The person whose life the income payments are measured by (the "measuring life"). Often the same as the owner.
• Beneficiary – Receives any remaining value if the annuitant/owner dies before payments are exhausted.
• Insurer – Holds the funds and makes the payments.

The two phases: accumulation vs. annuitization

Every annuity has up to two phases:

• Accumulation (pay-in) phase – The period when money is paid in and grows tax-deferred. Contributions can be a single lump sum or a series of payments.
• Annuitization (payout/distribution) phase – When the insurer converts the accumulated value into a stream of income payments. Once annuitized, the decision is generally irreversible, and the income is based on the account value, the payout option chosen, the annuitant's age/life expectancy, and an assumed interest rate.

The point where the contract switches from accumulation to payout is the annuity (or maturity) date.

Classifying annuities by how they grow

• Fixed annuity – The insurer guarantees a minimum interest rate and a fixed dollar payout. Money goes into the insurer's general account, so the insurer bears the investment risk. Payments are stable and predictable but may lose purchasing power to inflation. A life-only salesperson can sell fixed annuities.
• Variable annuity – Premiums go into a separate account invested in subaccounts (like mutual funds) chosen by the owner. Values and payouts rise and fall with market performance, so the owner bears the investment risk. Because they are securities, selling variable annuities requires both a life insurance license and a securities (FINRA) registration, and they come with a prospectus.
• Indexed (equity-indexed/fixed-indexed) annuity – Interest is tied to a market index (e.g., S&P 500), with growth limited by a cap and participation rate and protected by a floor (often 0%, so principal isn't lost to market drops). It's a middle ground between fixed and variable. A guaranteed minimum interest rate typically applies to a portion of the premium.

Classifying annuities by when income starts

• Immediate annuity – Purchased with a single premium, income payments begin within about one year (often the first month). Used to convert a lump sum (like a retirement rollover) into income right away. Also called a SPIA (single premium immediate annuity).
• Deferred annuity – Income payments begin more than a year in the future. Money accumulates tax-deferred until then. Funded by a single premium (SPDA) or flexible premiums (FPDA) paid over time. Deferred annuities have a cash/surrender value during accumulation; immediate annuities generally do not.

Payout (settlement) options

When it's time to receive income, the owner selects how payments are structured. The trade-off is always between larger payments and stronger guarantees to heirs.

Some contracts also allow annuity certain (fixed-period or fixed-amount) options that pay regardless of life, similar to life insurance settlement options.

Surrender charges

Deferred annuities usually carry surrender charges—penalties the insurer deducts if the owner withdraws more than a free-withdrawal amount (often around 10% per year) or cancels during the early surrender period. The charge typically starts high (e.g., 7%) and declines to zero over several years. Surrender charges let the insurer recover its upfront costs and discourage early withdrawals. (These are separate from any IRS tax penalties.)

A bonus annuity may credit an upfront percentage to the account, but often comes with longer surrender periods—an important suitability consideration.

Suitability

Because annuities are long-term products often sold to older consumers, regulators (following the NAIC Suitability in Annuity Transactions model) require producers to ensure a recommendation is suitable. Before recommending an annuity, the producer should reasonably believe it fits the consumer's:

• Financial situation, income needs, and liquidity needs.
• Age, time horizon, and risk tolerance.
• Existing assets and other insurance.
• Tax status and financial objectives.

Producers must be properly trained (including product-specific and suitability/best-interest training) and document the basis for the recommendation. Replacing an existing annuity demands extra scrutiny—watch for new surrender charges and lost benefits.

A high-level note on taxation

A few federal tax ideas to remember (covered more fully in the tax guide):

• Annuities grow tax-deferred—no tax on earnings during accumulation.
• For a nonqualified annuity (bought with after-tax dollars), withdrawals are taxed on a LIFO basis—earnings come out first and are taxable; the return of your principal is tax-free.
• During annuitization, the exclusion ratio determines what portion of each payment is tax-free return of principal versus taxable earnings.
• Withdrawals before age 59½ are generally hit with a 10% IRS penalty on the taxable portion, in addition to ordinary income tax.
• Annuity earnings are taxed as ordinary income, not capital gains.

Common exam traps

• Annuities protect against living too long; life insurance protects against dying too soon. Annuities are sometimes called the "upside-down" application of life insurance.
• In a fixed annuity the insurer bears investment risk; in a variable annuity the owner does.
• Variable annuities require a securities license; fixed annuities do not.
• Immediate vs. deferred is about WHEN income starts (within ~1 year vs. later), not how it's funded.
• Life-only pays the most but leaves nothing to heirs—if a question stresses "maximum income," that's usually the answer.
• Nonqualified annuity withdrawals are LIFO (earnings/taxable first).
• Surrender charges (insurer penalty) are different from the 10% IRS early-withdrawal penalty (tax).

Quick recap

• An annuity converts money into income you can't outlive, with an accumulation phase and an annuitization phase.
• By growth: fixed (insurer bears risk), variable (owner bears risk, securities license needed), and indexed (index-linked with cap/floor).
• By timing: immediate (income within ~1 year, single premium) vs. deferred (income later, single or flexible premiums).
• Payout options trade income size for guarantees: life only pays most; period certain, refund, and joint-and-survivor protect beneficiaries.
• Surrender charges decline over the surrender period; suitability rules require recommendations to fit the client's needs.
• Annuities grow tax-deferred, use LIFO taxation on nonqualified withdrawals, apply an exclusion ratio at payout, and face a 10% penalty before 59½.
