What an annuity does, and what it costs

An annuity is a contract with an insurance company: you give them a lump sum of money (or make payments over time), and they promise to send you regular payments for a set period or for the rest of your life. The trade-off is that your money is locked in — you cannot easily withdraw it without penalties, and the insurance company takes a cut through fees and by keeping some of the investment returns.

From a tax perspective, annuities matter because they change when and how much you owe. Money inside an annuity grows without annual tax bills, which sounds good. But when you withdraw it, the gains are taxed as ordinary income (not the lower capital gains rate), and if you withdraw before age 59½, you typically face a 10% penalty on top of income tax. The real decision is whether that tax deferral benefit outweighs the cost of fees and lost flexibility.

Key Takeaways

  • Annuities defer taxes on investment growth inside the contract, but withdrawals before 59½ usually trigger a 10% penalty plus income tax on the gains.
  • Annuity fees (often 1% to 3% per year, plus surrender charges if you withdraw early) can eat into returns more than the tax deferral saves you.
  • Income from an annuity in retirement is taxed as ordinary income, not capital gains, which may result in a higher tax bill than other investment strategies.
  • Annuities can affect your Medicare premiums and Social Security taxation because the income counts toward your modified adjusted gross income.
  • Whether an annuity makes tax sense depends on your age, how long you plan to hold it, and whether you have other tax-deferred accounts like a 401(k) or IRA.

How the tax deferral works inside an annuity

When you invest in a regular taxable account, you pay tax each year on dividends and capital gains, even if you do not withdraw the money. Inside an annuity, those gains are not taxed annually — they compound without a yearly tax bill. This is the same benefit you get from a 401(k) or traditional IRA, and it can be meaningful over decades.

The catch is that this deferral is not free. You pay for it through fees charged by the insurance company. A typical annuity charges 1% to 3% per year in management and insurance fees, plus surrender charges (often 5% to 10% of your withdrawal) if you take money out in the first 5 to 10 years. Those fees come out of your account before you see any returns, so the tax deferral has to overcome them to be worth it.

The math works best if you hold the annuity for a long time (15+ years) and have a large sum to invest. If you need access to your money sooner, or if you are investing a small amount, the fees often outweigh the tax benefit.

Tax treatment when you start withdrawing

When you withdraw money from an annuity, the tax bill depends on whether you are taking a lump sum or receiving regular payments. If you withdraw a lump sum, the gains (everything above what you put in) are taxed as ordinary income in that year, which can push you into a higher tax bracket. If you receive regular payments, part of each payment is your original contribution (not taxed) and part is gains (taxed as ordinary income).

This ordinary income treatment is less favorable than capital gains rates. Long-term capital gains are taxed at 0%, 15%, or 20% depending on your income. Annuity gains are taxed at your full ordinary income rate, which can be 22%, 24%, 32%, 35%, or 37%. Over a 20-year holding period, that difference can cost you thousands in extra tax.

If you withdraw before age 59½, you also owe a 10% penalty on the gains portion (not your contributions). This penalty is separate from income tax, so a withdrawal at age 50 could mean 10% penalty plus 24% income tax, for a 34% total hit on the gains.

The early withdrawal penalty and exceptions

The 10% penalty on withdrawals before 59½ applies to most annuities, but there are narrow exceptions. You can avoid the penalty if you are disabled, if you are receiving substantially equal periodic payments (a specific IRS formula), or if you are withdrawing from a may have access to annuity (one held inside a 401(k) or IRA) and meet that account's rules.

Some annuities also allow you to withdraw a small percentage each year (often 10%) without penalty, even before 59½. Read the contract to see what your annuity permits. Even with these exceptions, you still owe income tax on the gains — the penalty is just the extra 10% on top.

If you think you might need the money before 59½, an annuity is usually the wrong choice. A taxable brokerage account gives you full access without penalties, and you can manage the tax bill by using tax-loss harvesting or holding investments long-term for capital gains rates.

How annuities affect your other tax bills

Annuity income counts toward your modified adjusted gross income (MAGI), which determines whether you owe extra Medicare premiums and how much of your Social Security is taxed. If you are 65 or older and receiving annuity payments, higher MAGI can trigger income-related monthly adjustment amounts (IRMAA) that increase your Medicare Part B and Part D premiums by $70 to $560+ per month, depending on your income.

This is often overlooked. A retiree who takes $30,000 per year from an annuity might see $200 to $300 of that go to higher Medicare premiums, on top of the ordinary income tax. When you are deciding whether to annuitize (convert a lump sum into regular payments), factor in the full tax and premium impact, not just the income tax rate.

If you are still working and contributing to a 401(k), annuity withdrawals do not reduce your ability to contribute. But they do count toward the income thresholds for Roth IRA contributions and for deducting traditional IRA contributions if you are covered by a workplace plan.

Comparing annuities to other tax-deferred accounts

Before you buy an annuity, consider whether you have unused room in a 401(k), traditional IRA, or backdoor Roth IRA. These accounts also defer taxes, but they have lower fees (often under 0.5% per year with a low-cost provider), no surrender charges, and more flexibility. A 401(k) lets you borrow against your balance; an IRA lets you withdraw contributions anytime without penalty.

Annuities make the most sense if you have already maxed out your 401(k) and IRA contributions and you want additional tax deferral. They also appeal to people who want a may provide income stream in retirement and are willing to pay for that insurance. But if your main goal is tax deferral, a low-cost index fund in a taxable account often beats an annuity once you factor in fees.

The exception is a may have access to longevity annuity contract (QLAC), which is a special type of annuity held inside a 401(k) or IRA. QLACs have lower fees and can defer required minimum distributions (RMDs), making them more tax-efficient for some retirees. If you are considering an annuity, ask whether a QLAC fits your situation.

When an annuity makes tax sense

An annuity is worth considering if you are over 59½, have a large sum to invest (at least $100,000), plan to hold it for 15+ years, and want to lock in a may provide income stream. The tax deferral benefit is real over that time horizon, and the insurance company's may provide has value if you are worried about market downturns or outliving your money.

It makes less sense if you are under 59½ (the penalty is too costly), if you have a short time horizon (fees eat the gains), or if you have not maxed out your 401(k) and IRA (those accounts are cheaper and more flexible). It also makes less sense if you are in a low tax bracket now and expect to be in a higher one in retirement — you would be deferring tax at 12% and paying it back at 24%, which is a bad trade.

Run the numbers with a tax professional or fee-only financial planner before you commit. Ask them to model the annuity against a taxable brokerage account and against maxing out your 401(k) or IRA. The best choice depends on your specific situation, not on the annuity company's marketing.

Frequently Asked Questions

Do I owe tax on annuity contributions?

No. The money you put into an annuity is your contribution, and you do not owe tax on it when you withdraw it. You only owe tax on the gains (the earnings the annuity generated). If you bought the annuity with after-tax money, your contributions come out tax-free; if you bought it with pre-tax money (like a rollover from a 401(k)), the entire withdrawal is taxed.

What happens to my annuity if I die before I start withdrawing?

That depends on the contract. Most annuities let your beneficiary withdraw the remaining balance, which is taxed as ordinary income to them. Some annuities are "life only" and pay nothing to beneficiaries — the insurance company keeps the rest. Read your contract or ask the insurance company before you buy, because this affects the real value of your investment.

Can I move money out of an annuity without the surrender charge?

Some annuities allow a 1035 exchange, which lets you move the money to a different annuity without triggering the surrender charge or a tax bill. However, you start a new surrender period with the new annuity, so you are not really avoiding the lock-in. This is useful only if you are switching to a much lower-fee annuity.

Does an annuity count as income for Social Security taxation?

Yes. Annuity payments count toward your combined income, which determines how much of your Social Security is taxed. If your combined income is over $25,000 (single) or $32,000 (married filing jointly), up to 85% of your Social Security can be taxed. An annuity withdrawal can push you over that threshold and create a surprise tax bill.

What if I have a variable annuity with subaccounts?

Variable annuities let you choose how the money is invested (stocks, bonds, etc.), and the payout depends on investment performance. The tax rules are the same as fixed annuities — gains are taxed as ordinary income, and the 10% penalty applies before 59½. However, variable annuities often have higher fees (2% to 4% per year) because of the investment management, making them even less attractive than fixed annuities from a tax perspective.
