When Is Flexible Premium Deferred Annuity Interest Taxed?

Interest credited to a flexible premium deferred annuity is not taxed while it stays inside the contract. The IRS does not require you to report that growth on your annual return, and the insurance company will not issue a tax form just because your account value went up. Tax comes due only when money actually leaves the contract, whether through a withdrawal, a surrender, a loan against it, annuitized income payments, or certain transfers of ownership.¹

While the Money Stays in the Contract

The appeal of a deferred annuity is that credited interest compounds without an annual tax drag. You pay premiums in, the insurer credits interest each year, and none of that growth shows up on your 1040. The IRS treats it as unrealized until a distribution event forces it out.

This deferral applies to non-qualified annuities purchased with after-tax dollars. The premiums you paid are your basis, sometimes called your investment in the contract. That money has already been taxed and will never be taxed again. Only the earnings layer, the part above your basis, is ever subject to income tax, and only when it leaves the contract.

One boundary worth knowing: if a corporation, business, or certain trust owns the annuity rather than a living person, the deferral generally disappears. Under Section 72(u), the contract is not even treated as an annuity for tax purposes, and the entity owes tax each year on the income as it accrues. Narrow exceptions exist for estates holding an inherited contract, annuities inside qualified retirement plans, immediate annuities, and trusts acting purely as agent for a natural person.¹

Events That Make the Interest Taxable

Tax deferral ends the moment value moves out of the contract, or in some cases the moment you treat the contract as if it had. The common triggers are a partial withdrawal, a full surrender, and annuitization into a stream of income payments. Each forces you to recognize some or all of the previously untaxed interest.

Less obvious triggers catch owners by surprise. 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 own the contract.¹ Transferring ownership of the contract to another person for value also creates a taxable event. The underlying principle is consistent: if you access the contract’s value in any form, the earnings layer becomes reportable income.

How Much of a Withdrawal Is Taxable

When you take a partial withdrawal from a non-qualified deferred annuity, the IRS applies an earnings-first ordering rule under Section 72(e). Every dollar coming out is treated as taxable interest until the entire accumulated gain has been withdrawn. Only after that earnings layer is exhausted do further withdrawals come back as tax-free return of your basis.¹

Say you have paid $80,000 in premiums and the contract is now worth $100,000. The $20,000 difference is accumulated interest. If you withdraw $15,000, the full $15,000 is taxable as ordinary income because it falls entirely within that earnings layer. You would need to pull more than $20,000 before any portion came back tax-free.

People sometimes assume withdrawals split proportionally between interest and basis. They do not. The tax comes first, and recovery of your original premiums comes last.

There is one wrinkle for owners of multiple contracts. If you buy more than one annuity from the same insurer in the same calendar year, Section 72(e)(12) treats them as a single contract when calculating the taxable portion of a withdrawal. Contracts from different insurers, or from the same insurer in different years, are figured separately.¹

How Annuitized Payments Are Taxed

Once you annuitize the contract and start receiving periodic income payments, the earnings-first rule stops applying. Each payment is divided into a taxable portion and a tax-free return of basis using the exclusion ratio. The formula divides your investment in the contract by the expected total return over the payout period, and the resulting percentage of every payment comes back to you tax-free.²

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

For annuity starting dates after 1986, the total you recover tax-free over the years cannot exceed your net investment in the contract. Once your full basis has been returned, every later payment is 100% taxable. Outlive your life expectancy and the later checks are entirely ordinary income.

The 10% Penalty Before Age 59½

On top of regular income tax, taking money out before age 59½ triggers a 10% additional tax on the taxable portion of the distribution. Section 72(q) imposes this penalty on any withdrawal where earnings are included in gross income.¹

The statute lists specific escapes from the penalty:

Distributions on or after the owner reaches age 59½.
Distributions to a beneficiary after the owner’s death.
Distributions attributable to the owner becoming totally and permanently disabled.
A series of substantially equal periodic payments calculated over your life expectancy or joint life expectancies, taken at least annually. Once started, the series generally must continue for five years or until you reach 59½, whichever is later.
Payments from an immediate annuity, meaning a single-premium contract that begins paying within one year of purchase.
The portion of a distribution allocable to investment in the contract before August 14, 1982.

The exceptions for first-time home purchases, higher education, and medical expenses that apply to IRAs and 401(k)s do not apply to non-qualified annuities. If you need early access, substantially equal periodic payments are the usual route, and the calculation has to be correct from the start. Breaking the series early can retroactively apply the penalty to every payment already taken.

When the Owner Dies

An inherited annuity does not get a stepped-up basis the way inherited stocks or real estate do. The accumulated interest inside the contract stays taxable as ordinary income to whoever receives it.

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

A surviving spouse has an option no one else gets. The tax code lets the spouse be treated as the new holder of the contract, continuing it in their own name and keeping the deferral going. Non-spouse beneficiaries have to take distributions and pay the tax on the earnings as they come out.

Moving to Another Annuity Without Triggering Tax

If you want to switch annuities without recognizing the 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 money has to move directly from one insurer to the other. If it passes through your hands, the exchange fails and the whole gain becomes taxable. Your original basis carries over to the new contract, so the tax is postponed, not eliminated.

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

Withholding and the 1099-R

When you take a non-periodic distribution, such as a lump sum, partial withdrawal, or full surrender, the insurer withholds 10% of the taxable amount for federal income tax by default. You can change that rate or elect out of withholding entirely by filing Form W-4R with the insurer.⁵ Periodic annuity payments use Form W-4P, which works more like paycheck withholding.

Every distribution is reported on Form 1099-R. Box 1 shows the gross amount, Box 2a shows the taxable portion calculated under either the earnings-first rule or the exclusion ratio, and Box 7 carries a distribution code identifying the type of payment.⁶ You should receive the form by January 31 of the following year.⁷ The Box 2a figure flows onto your 1040 as ordinary income, and if the 10% early withdrawal penalty applies you file Form 5329 to calculate the additional tax. The default 10% withholding may not cover the full bill, especially if the penalty is in play or your bracket is higher, so expect to settle the balance at filing time.
