What Is an Annuity?
An annuity is a contract between you and an insurance company. You pay a premium — either a lump sum or a series of payments — and the insurer promises to pay you income, starting either immediately or at a future date. The SEC's investor education resources describe annuities as products designed primarily to help fund retirement income.
There are three main types: fixed, variable, and indexed. Each has a different risk profile, fee structure, and tax implication. Choosing the wrong type for your situation can be costly — surrender charges can lock up your money for 6 to 10 years.
Fixed Annuities
A fixed annuity credits a declared interest rate for a specified term, similar to a certificate of deposit. The insurance company bears the investment risk: you earn the declared rate regardless of how markets perform.
The rate is typically guaranteed for an initial period (commonly 1–5 years), after which it adjusts to current market rates at renewal. Your principal and minimum guaranteed interest are backed by the insurer's claims-paying ability — not by federal deposit insurance.
Fixed annuities suit savers who want predictable, guaranteed growth without market exposure. The tradeoff: declared rates typically lag long-run equity returns, and inflation erodes purchasing power on fixed payments over a long retirement.
Variable Annuities
Variable annuities invest your premiums in sub-accounts — pools that function like mutual funds — and your account value rises and falls with market performance. FINRA's variable annuity investor guide is direct about the risk: variable annuities can lose value if sub-accounts underperform.
Total annual costs frequently reach 2% to 3% or more when mortality and expense charges, sub-account fund fees, and optional rider fees are combined — significantly higher than holding comparable mutual funds inside an IRA directly.
Many variable annuities include optional "living benefit" riders that guarantee a minimum income or withdrawal amount regardless of sub-account performance. These riders are a core selling point but add 0.5% to 1.5% to annual fees. Before buying a living benefit rider, calculate whether the guarantee is worth what you're paying for it over a 20- or 30-year horizon.
Indexed Annuities
Indexed annuities (also called fixed indexed annuities, or FIAs) offer a middle path: returns are linked to a market index such as the S&P 500, but a contractual floor prevents outright losses and a cap or participation rate limits upside.
For example: an annuity with a 0% floor, 25% participation rate, and the S&P 500 up 20% in a given year credits roughly 5% (20% × 25%). If the index falls 15% that year, you receive 0% — your account doesn't decline, but you earn nothing either.
The SEC investor education resources on annuities note that caps and participation rates can change at renewal, and prospective buyers should read the full contract — including how the index return is calculated — before signing.
How Annuities Are Taxed
All three annuity types share the same federal tax framework under IRS Publication 575 (Pension and Annuity Income):
- Tax-deferred growth: earnings inside the annuity accumulate without annual tax — they compound untouched until withdrawal.
- Ordinary income on withdrawal: distributions are taxed at your regular federal income tax rate, not at the lower capital gains rate — even if the underlying growth came from equity sub-accounts.
- 10% early withdrawal penalty: distributions before age 59½ trigger the same 10% federal penalty that applies to IRAs and 401(k)s.
- Exclusion ratio for income payments: only the earnings portion of annuity income payments is taxable — your original after-tax premium is returned to you tax-free over the payment period.
One important implication: a variable annuity inside a traditional IRA adds no additional tax deferral — the IRA already provides it. In that scenario, the annuity's higher annual fees represent pure cost with no offsetting tax benefit.
Surrender Charges: Read the Contract Before Signing
Most deferred annuities carry a surrender period — typically 6 to 10 years — during which withdrawal above the contract's free-withdrawal allowance triggers a surrender charge. Per SEC guidance, surrender charges often start at 7–8% in year one and decline by roughly 1 percentage point per year until the surrender period ends.
Surrender charges exist because insurance companies pay upfront commissions to the agents or advisors who sell the product — commissions that can range from 3% to 10% depending on annuity type. Those costs are embedded in the contract structure rather than billed separately.
Before purchasing any annuity, confirm:
- The full length of the surrender period
- The charge schedule year by year
- The free-withdrawal allowance (many contracts permit 10% of account value annually without a charge)
- Any death benefit provisions and what they cost
When an Annuity Might Fit Your Plan
An annuity can be the right tool when you've maxed out your 401(k), IRA, and HSA contributions and still want tax-deferred growth — the annuity provides deferral on money that would otherwise sit in a taxable account. It can also make sense if you specifically want guaranteed lifetime income you can't outlive, or if you're near retirement and want principal protection with some market participation.
It's typically not the right tool when you're still accumulating inside a 401(k) or IRA (those vehicles already defer taxes, without annuity fees), when you may need the money within the surrender period, or when you're in a moderate tax bracket comparing it to low-cost index funds held in a taxable account.
If you're building a retirement income plan that includes an annuity, the decision interacts directly with your Social Security claiming strategy — both are sources of guaranteed income in retirement, and the mix between them affects your overall tax bracket and income needs. It also connects to your Roth vs. traditional IRA allocation, which determines what pre-tax income you'll have to convert or withdraw in retirement.
Who Regulates Annuities
Fixed and indexed annuities are insurance products regulated by state insurance commissioners — not the SEC or FINRA. Variable annuities are also registered securities, so they're regulated by both state insurance departments and the SEC and FINRA as securities products. Most states have insurance guaranty associations that protect contract holders up to state-specific limits — typically $100,000 to $250,000 on the cash value — if an insurer becomes insolvent.
