Annuities Explained: When They Help and What to Watch For
An annuity is an insurance contract that turns savings into income. Simple income annuities address longevity risk; complex ones can carry high fees.
Annuities Explained: When They Help and What to Watch For
1 / 7
What is an annuity?
- An annuity is a contract with an insurance company: you pay a lump sum or a series of premiums, and the insurer pays income now or later.
- Its core function is longevity insurance, turning savings into income that can last for life, backed by the insurer's claims-paying ability.
- Earnings grow tax-deferred, but the gain portion of withdrawals is taxed as ordinary income, not at capital gains rates.
- Costs, liquidity, and complexity vary widely, so the contract terms matter more than the product label.

What is an annuity?
- An annuity is a contract with an insurance company: you pay a lump sum or a series of premiums, and the insurer pays income now or later.
- Its core function is longevity insurance, turning savings into income that can last for life, backed by the insurer's claims-paying ability.
- Earnings grow tax-deferred, but the gain portion of withdrawals is taxed as ordinary income, not at capital gains rates.
- Costs, liquidity, and complexity vary widely, so the contract terms matter more than the product label.
What are the main types of annuities?
- Single premium immediate annuity (SPIA): a lump sum buys lifetime or fixed-period income that starts within about a year.
- Deferred income annuity: income starts years later; a qualified longevity annuity contract (QLAC) lets part of an IRA or 401(k) buy one and defer RMDs on that amount.
- Fixed (multi-year rate) annuity: credits a declared interest rate for a set term, similar in concept to a CD but with surrender charges.
- Variable annuity: invested in market subaccounts whose value rises and falls, often with optional living or death benefit riders at extra cost.
- Fixed indexed annuity: credits interest based on an index, subject to caps, participation rates, and a floor, using formulas that are hard to compare.
When can an annuity make sense?
- When someone wants a predictable income floor that, with Social Security or a pension, covers essential spending.
- When longevity is a real concern, since pooling mortality risk lets an insurer pay lifetime income that a self-managed portfolio cannot commit to.
- When a deferred income annuity starting at 80 or 85 is used to address the risk of a very long life at a lower upfront cost than immediate income.
- The trade-offs: purchased income is usually illiquid, often not inflation-adjusted, and depends on the insurer's financial strength.
What are the red flags?
- Surrender charges that often last several years, sometimes seven to ten, and apply to withdrawals above a free-withdrawal amount.
- Layered variable-annuity costs, including mortality and expense charges, administrative fees, subaccount expenses, and rider charges, listed in the prospectus fee table.
- Sales commissions paid to the agent, which create an incentive that may not align with the buyer's interests.
- Rider illustrations built on a 'benefit base' that is not cash you can withdraw as a lump sum.
- Exchanging one annuity for another (a 1035 exchange) can restart a surrender schedule and add new costs.
Annuity taxation
- Nonqualified annuity withdrawals come out earnings-first, taxed as ordinary income, with a 10% additional tax before 59½ unless an exception applies.
- Annuitized payments split each check into a tax-free return of basis and taxable earnings using an exclusion ratio.
- Annuities get no step-up in basis at death, so heirs owe ordinary income tax on the deferred gain.
- Inside an IRA or 401(k), an annuity adds no extra tax deferral, so its value has to come from income or insurance features, weighed against cost.
Evaluating an annuity before buying
- Ask for all annual costs in dollars, the full surrender schedule, and what you would receive if you needed the money out early.
- Compare quotes from several insurers, since payout rates for the same income annuity can differ meaningfully.
- Check the insurer's financial-strength ratings and your state guaranty association's coverage limits.
- Use the state-mandated free-look period, often 10 to 30 days, to review the contract before the cancellation right expires.
Key takeaways
- Simple income annuities address longevity risk directly; variable and indexed products require close reading of fees, caps, and surrender terms.
- Tax deferral alone rarely offsets high ongoing costs, and it adds nothing inside an already tax-deferred account.
- Commission-based sales create conflicts, so an independent review by a fee-only adviser who earns no commissions can be useful.
- Confirm the tax treatment of any purchase or exchange with a CPA before signing.
