When Is Interest on a Flexible Premium Deferred Annuity Taxed?

Interest inside a flexible premium deferred annuity is taxed only when money comes out of the contract. While the account is accumulating, the interest credited each year is not reportable income and the insurer does not issue a tax form for it. The tax event happens when you withdraw funds, surrender the contract, take a loan or pledge it as collateral, annuitize into a stream of payments, or transfer ownership for value. At that point, previously untaxed earnings become ordinary income, and if you are under 59½ a 10% additional tax may apply on top.

Nothing Is Taxed While the Contract Is Growing

The whole point of a deferred annuity is that earnings compound without an annual tax drag. You pay premiums in, the insurer credits interest or investment gains, and the IRS treats that growth as unrealized until a distribution event forces it into the open.¹

For a non-qualified annuity bought with after-tax money, the premiums you paid are your basis, sometimes called your investment in the contract. That basis will never be taxed again. Only the earnings layer will ever be taxable, and only when it leaves the contract.

What Actually Triggers Tax

Deferral ends the moment value moves out of the contract, or the moment you use the contract to get value in some other form. The obvious triggers are a partial withdrawal, a full surrender, or annuitizing and beginning periodic income payments.

The less obvious triggers surprise people. Under Section 72(e)(5)(A), borrowing against your annuity or pledging it as collateral for a loan is treated as a taxable distribution, even though you still hold the contract.¹ Transferring ownership of the contract to another person for value also creates a taxable event. If you access the contract’s value in any form, the earnings get taxed.

How Much of a Withdrawal Is Taxable

Section 72(e) applies an earnings-first ordering rule to withdrawals from a non-qualified deferred annuity. Every dollar you pull out is treated as taxable earnings until the entire accumulated gain has been distributed. Only after that layer is exhausted do further withdrawals come back as a tax-free return of your premiums.¹

Say you’ve paid $80,000 in premiums and the contract is now worth $100,000. The $20,000 of growth is your earnings layer. Withdraw $15,000 and the whole $15,000 is taxable as ordinary income, because it all sits inside that earnings layer. You would have to pull out more than $20,000 before any portion started coming back tax-free.

There is no pro-rata split between basis and earnings on a withdrawal from a non-qualified deferred annuity in accumulation. The taxable portion comes out first.

Multiple Contracts With the Same Insurer

If you own more than one annuity contract issued by the same insurance company in the same calendar year, Section 72(e)(12) aggregates them and treats them as a single contract for the earnings-first calculation.¹ Contracts from different insurers, or from the same insurer but different calendar years, are calculated separately.

How Annuitized Payments Are Taxed

Once you annuitize the contract and start receiving a stream of periodic payments, the earnings-first rule no longer applies. Each payment is split into a taxable portion and a tax-free return of basis using the exclusion ratio: your investment in the contract divided by the expected total return over the payout period. The resulting percentage of each payment comes back tax-free.²

If you invested $100,000 and your expected total return over life expectancy is $200,000, the exclusion ratio is 50%. Half of each payment is tax-free basis recovery, half is ordinary income. The ratio stays fixed for the life of the payout.

For annuity starting dates after 1986, tax-free recovery stops once you have recovered your full basis. From that point on, every payment is 100% taxable. If you outlive the actuarial expectancy the exclusion ratio was built on, the later payments become fully taxable ordinary income.

The 10% Additional Tax Before Age 59½

On top of ordinary income tax, taking earnings out of a deferred annuity before age 59½ generally triggers a 10% additional tax under Section 72(q). It applies to the taxable portion of the distribution — the same portion that would already be taxed as ordinary income.¹

The 10% is waived only for a narrow set of situations, including distributions taken at or after age 59½, distributions after the owner’s death, distributions attributable to the holder’s total and permanent disability, substantially equal periodic payments over life expectancy (which generally must continue for at least five years or until age 59½, whichever is later), and immediate annuities that begin paying within one year of a single premium.

The exceptions people know from IRAs and 401(k)s — first home purchase, higher education, medical expenses — do not apply to non-qualified annuity contracts. The escape hatches here are narrower than most retirement savers assume.

Tax When the Owner Dies

An inherited annuity does not get a stepped-up basis. The gains inside the contract remain ordinary income to whoever receives them.

If the owner dies during the accumulation phase, the entire contract value generally has to be distributed within five years. A named individual beneficiary can instead stretch distributions over their own life expectancy if payments begin within one year of the death.¹ If the owner dies after annuitizing, remaining payments must continue at least as rapidly as the method already in use.

A surviving spouse is treated as the new holder of the contract and can keep the annuity in force in their own name, preserving the deferral. No other beneficiary gets that treatment; non-spouse beneficiaries must take distributions and pay tax on the earnings portion.

Moving to Another Annuity Without Triggering Tax

If you want to switch contracts without recognizing gain, Section 1035(a)(3) allows a direct exchange of one annuity contract for another (or for a qualified long-term care contract) with no gain or loss recognized.³ The transfer has to go directly from one insurer to the other. If the money passes through your hands, the exchange fails and the full gain becomes taxable. Your original basis carries over to the new contract, so the tax is postponed, not erased.

Partial 1035 exchanges are allowed too. Under Revenue Procedure 2011-38, you can move part of one annuity’s value into a new contract tax-free, provided no distributions are taken from either contract within 180 days of the transfer.⁴

Withholding and the 1099-R

For a non-periodic distribution (a lump-sum withdrawal or a surrender), the insurer withholds 10% of the taxable amount for federal income tax by default. You can change the rate or elect out entirely by filing Form W-4R with the company; if you file nothing, 10% is withheld.⁵

Every distribution is reported on Form 1099-R. Box 1 shows the gross amount, Box 2a shows the taxable portion (calculated under the earnings-first rule or the exclusion ratio, depending on the type of distribution), and Box 7 carries a code identifying the distribution type.⁶ You’ll receive the form by January 31 of the year after the distribution.⁷ The Box 2a amount flows onto your Form 1040 as ordinary income, and if the 10% early-distribution tax applies, you report it on Form 5329. The default 10% withheld often will not cover the actual bill, especially in a higher bracket or when the early-distribution tax stacks on top.

One Boundary: Non-Individual Ownership

Everything above assumes an individual owner. If a corporation or certain trust owns the deferred annuity, Section 72(u) generally strips the tax deferral: the contract is not treated as an annuity for tax purposes, and the entity has to report the contract’s income each year as ordinary income even without any withdrawal.¹ Narrow exceptions exist, including trusts holding the contract as agent for a natural person, but the default is that placing a deferred annuity inside a non-individual owner defeats the deferral it was bought for.
