What Is a Tax-Deferred Annuity and How Does It Work?

A tax-deferred annuity is a contract with an insurance company that lets your investment earnings grow year after year without being taxed, so the full balance keeps compounding until you take money out. When you do withdraw, the earnings are taxed as ordinary income. The contracts come in several flavors with different risk profiles, and the IRS applies specific rules to early withdrawals, required distributions, and how gains are ultimately taxed.

How the Tax Deferral Actually Works

Any interest, dividends, or investment gains the contract earns stay inside the account, untouched by taxes, for as long as you hold them there. In a regular brokerage account you’d owe tax on dividends and realized gains every year, which shrinks the balance that keeps working for you. Inside an annuity, those earnings compound at their full value.

The benefit grows with time. The longer money sits without tax drag, the wider the gap between what you’d accumulate inside an annuity versus a taxable account. There’s a trade-off, though. When you eventually withdraw, gains come out as ordinary income rather than at the lower long-term capital gains rates a brokerage account would use. For someone who expects a lower tax bracket in retirement than during their working years, the math still favors deferral.

Qualified vs. Non-Qualified Annuities

How your contributions are taxed depends on where the money came from. A qualified annuity sits inside a tax-advantaged retirement account like a traditional IRA or an employer plan. The money going in was never taxed, so the entire withdrawal (contributions plus earnings) is taxed as ordinary income when it comes out.¹ Qualified annuities use the contribution limits of the underlying retirement plan.

A non-qualified annuity is bought with money you’ve already paid income tax on. Because the principal was after-tax dollars, you aren’t taxed on it again when you withdraw. Only the earnings portion is taxable.² Non-qualified annuities have no IRS contribution cap, which is part of their appeal to high earners who’ve already maxed out IRA and 401(k) space.

Both types defer tax on earnings during accumulation. The split matters at distribution: whether the whole payment or only the gain is taxable.

The Main Types

Fixed Annuities

A fixed annuity guarantees a set interest rate for a specific period, commonly three to ten years. You know what you’ll earn and your principal is protected. After the initial guarantee period, the insurer resets the rate, which may be higher or lower depending on the rate environment at the time. These contracts suit people who want predictable growth and no market exposure.

Variable Annuities

A variable annuity lets you invest in subaccounts that work like mutual funds. Your returns depend on how those investments perform, so you carry the market risk. Strong markets can produce returns well above a fixed annuity; downturns can cut your account value. Most variable annuities include a standard death benefit guaranteeing that your beneficiary receives at least the original investment, minus any withdrawals, even if the subaccounts have fallen.

Variable annuities also carry the highest internal expenses of the three types, which is covered under fees below.

Fixed-Indexed Annuities

Fixed-indexed annuities (FIAs) sit between fixed and variable. Returns are tied to a market index such as the S&P 500, but you don’t own the index. Instead, the insurer uses three mechanisms to shape your upside and downside:³

A floor, the minimum return guaranteed regardless of index performance, often 0%, meaning your account value won’t drop when the index does.
A cap, the maximum percentage of the index gain credited to your account in a given period.
A participation rate, the percentage of the index return you actually get. An 80% participation rate on a 10% index gain gives you 8%, still subject to the cap.

An FIA protects principal in downturns, but the cap and participation rate mean you won’t capture the full index return in strong years. The insurer can also adjust the cap and participation rate at each contract anniversary, so today’s crediting terms aren’t locked in forever.

How Withdrawals Are Taxed

For non-qualified annuities, the IRS treats every dollar you withdraw as coming from earnings first. Under Section 72(e), withdrawals before the annuity starting date are included in gross income to the extent they’re allocable to income on the contract.² In practice, you pay ordinary income tax on every withdrawal until all the accumulated gains are out. Only then do withdrawals start coming from your original after-tax contributions, which come out tax-free.

If you annuitize the contract and convert it into a stream of periodic payments, each payment is split between taxable earnings and tax-free return of principal. The IRS calls this the General Rule: your cost basis divided by the expected total return over the payment period determines what fraction of each payment is tax-free.⁴ That spreads the tax across many years instead of concentrating it.

A lump-sum withdrawal does the opposite. It pushes all the accumulated gains into a single tax year, which can bump you into a higher bracket and produce a far bigger tax bill than paced distributions would.

For qualified annuities, the entire distribution is taxed as ordinary income, because none of the money going in was ever taxed.¹

The 10% Early Withdrawal Penalty

Pull money out before age 59½ and the IRS adds a 10% penalty to the taxable portion of the withdrawal, on top of the ordinary income tax you already owe. For non-qualified annuities, the penalty comes from Section 72(q). For qualified annuities inside IRAs or employer plans, a parallel penalty applies under Section 72(t).²

Common exceptions include:

Reaching age 59½.
Death of the owner, with distributions going to beneficiaries.
Total and permanent disability of the owner.
Substantially equal periodic payments (SEPP) taken over your life expectancy, made at least annually.
Contracts structured as immediate annuities, which are exempt entirely.

SEPP is the most common path for people under 59½ who need access to the money, but it comes with a serious commitment. Once you start, you have to keep the payments going for at least five years or until you reach 59½, whichever is longer. Modify or stop them early and the IRS retroactively applies the 10% penalty to every distribution you’ve already taken under the plan.⁵

Required Minimum Distributions

If your annuity sits inside a qualified retirement account, you’ll eventually face required minimum distributions. Under current rules, RMDs must start by April 1 of the year after you turn 73. That age moves to 75 starting in 2033 for people born in 1960 or later.⁶

Miss one and the penalty is a 25% excise tax on the shortfall. Catch the mistake and take the missed amount within the correction window (roughly two years) and the penalty drops to 10%.⁷

Non-qualified annuities are not subject to RMDs during the owner’s lifetime, which is a large part of their appeal for people who don’t need the income right away and want maximum deferral.

Swapping Contracts Without Triggering Tax

If you’re unhappy with your annuity’s fees, performance, or features, you can swap it for a new one without paying tax. Section 1035 lets you exchange an annuity for another annuity, or for a qualified long-term care policy, with no gain or loss recognized.⁸ You can also exchange a life insurance policy into an annuity, but not the other direction. An annuity can’t be swapped tax-free for life insurance.

The exchange has to be a direct transfer between insurance companies. If the money passes through your hands, the IRS treats it as a taxable withdrawal followed by a new purchase, and gains become taxable. The contract owner also has to stay the same on both the old and new contracts.⁹

A 1035 exchange doesn’t erase the new contract’s surrender schedule. You can land in a fresh surrender period of five to ten years, and if the new contract carries higher internal fees, the tax savings may not cover the cost difference. Work the numbers before swapping.

Fees and Surrender Charges

Annuities are not cheap to own, and the costs are not always obvious. Fees matter more here than with most investments because they compound against you for what can be a multi-decade holding period.

Surrender charges are the most immediate cost if you need the money early. Most contracts impose a declining penalty on withdrawals during the first several years, commonly starting around 7% in year one and dropping to zero over five to ten years. Most contracts also let you withdraw up to 10% of the account value each year without triggering a surrender charge.

Variable annuities carry ongoing internal expenses pulled from your account value daily. The biggest is the mortality and expense (M&E) risk charge, which pays the insurer for the contract guarantees. M&E charges across the industry run from roughly 0.15% on low-cost share classes to 1.50% or more on commission-based contracts with enhanced death benefits, with an industry average around 1.19%. Administrative and distribution fees add another 0% to 0.60%.¹⁰ Optional riders like guaranteed lifetime withdrawal benefits or enhanced death benefits add further costs, often 0.50% to 1.00% per year each.

A variable annuity charging 2.5% in total annual fees has to earn 2.5% before your money actually grows. Over 20 years, that drag can eat a large share of what the tax deferral saved you.

Sales commissions run from about 1% to 8% of the contract value, though you won’t see them as a separate line item. Commissions are baked into the contract’s internal costs and surrender schedule. Fixed annuities and FIAs show lower visible fees because their costs are embedded in the spread between what the insurer earns on your money and what it credits to you.

Who Stands Behind the Guarantees

Every guarantee in an annuity contract (the fixed rate, the floor, the death benefit, the lifetime income promise) is only as reliable as the insurance company behind it. Annuities are not bank deposits and are not insured by the FDIC.¹¹

If an insurer fails, state guaranty associations provide a backstop. Most states cover annuity contract values up to $250,000 per owner, though specifics vary. Treat that as a floor rather than a reason to ignore financial strength. Before buying any annuity, check the insurer’s ratings from A.M. Best, S&P, or Moody’s. A strongly rated company is far more likely to honor its guarantees over the 20 or 30 years you may hold the contract.
