Annuity Taxation — Exclusion Ratio, Nonqualified Annuities, and the 10% Penalty

An annuity is a contract with an insurance company that turns a lump sum into a stream of income payments — for a fixed period, for life, or for the lives of two people. The tax rules for annuities turn on one fundamental idea: you already paid tax on the money you put into a nonqualified annuity (your after-tax premium dollars), so when payments come back out, you shouldn't pay tax again on those dollars. Only the earnings — the return above your original investment — are taxable income. Section 72 of the tax code governs this through the "exclusion ratio," which determines what fraction of each payment represents a tax-free return of your investment and what fraction is taxable earnings. Get this wrong on your tax return and you'll overpay taxes on income that isn't taxable. Additionally, § 72 imposes a 10% penalty tax on early distributions from nonqualified annuities (before age 59½) — with the same list of exceptions that applies to IRAs, including the substantially equal periodic payment (SEPP) exception.

Current Law (2026)

Parameter	Value
Core statute	26 U.S.C. § 72
Nonqualified annuity taxation	Only the earnings portion is taxable; original investment (basis) recovered tax-free via exclusion ratio
Exclusion ratio formula	Investment in contract ÷ Expected return under contract = Exclusion ratio applied to each payment
Fully qualified (IRA/401k) annuities	No exclusion ratio — entire payment is taxable (§ 72(d) simplified method applies for pension annuities)
Early distribution penalty	10% of taxable amount for distributions before age 59½ from nonqualified annuities (§ 72(q))
Exceptions to 10% penalty	Death, disability, SEPP, immediate annuity, qualified funding asset, plan termination proceeds
LIFO rule for partial withdrawals	Earnings come out first before basis (Last-In, First-Out for pre-annuitization withdrawals)
1035 exchange	Tax-free exchange of one annuity contract for another; preserves basis without current tax (§ 1035)
Inherited annuity	Non-spouse beneficiaries generally must receive payments within 5 years of annuitant's death or over beneficiary's life expectancy; income in respect of a decedent (IRD) rules apply
Structured settlement annuities	Periodic payments for personal physical injury are generally excluded from income under § 104; § 72 applies only to annuities that aren't otherwise excluded

Legal Authority

26 U.S.C. § 72(a) — General rule: gross income includes amounts received as an annuity under an annuity, endowment, or life insurance contract
26 U.S.C. § 72(b) — Exclusion of annuity payments: the portion of each annuity payment equal to the investment in the contract divided by the expected return is excluded from gross income; once the full investment has been recovered, all further payments are fully taxable
26 U.S.C. § 72(b)(2) — Cap on exclusion: the excluded portion cannot exceed unrecovered investment; if the annuitant dies before recovering all basis, the unrecovered amount is deductible on the final return
26 U.S.C. § 72(c)(1) — Investment in the contract: the sum of all premiums paid minus amounts received tax-free before the annuity starting date
26 U.S.C. § 72(c)(3) — Expected return: if payments depend on life expectancy, expected return is computed using IRS actuarial tables; if payments are for a fixed term, expected return is the sum of all scheduled payments
26 U.S.C. § 72(d) — Simplified method for qualified plan annuities: instead of the exclusion ratio, qualified employer retirement plan annuities use a simplified calculation (investment divided by number of anticipated payments from IRS table)
26 U.S.C. § 72(e) — LIFO rule for non-annuity distributions: withdrawals before the annuity starting date (partial cash surrenders, partial withdrawals from deferred annuities) are taxed as earnings first — basis is recovered only after all earnings have been distributed
26 U.S.C. § 72(q) — 10% penalty on nonqualified annuity early distributions: distributions before age 59½ are subject to a 10% additional tax on the taxable portion; exceptions mirror IRA rules (death, disability, SEPP, immediate annuity)

The Exclusion Ratio: How It Works

When a nonqualified annuity begins paying out (the "annuity starting date"), the IRS calculates an exclusion ratio that applies to every payment for the life of the contract:

The formula:

Exclusion ratio = Investment in contract ÷ Expected return under contract

Investment in contract: All the after-tax dollars you put in, minus any tax-free amounts received before annuitization (e.g., if you took some money out tax-free before starting the annuity).

Expected return: Determined by IRS actuarial tables if the annuity is life-contingent (e.g., life annuity, joint-life annuity). If it's a fixed-period annuity (e.g., 20 years certain), expected return is simply total scheduled payments.

Example: You invested $200,000 in a deferred annuity over the years, which grew to $350,000. You annuitize for life, and the IRS table shows expected return of $500,000 (based on your age and life expectancy). Exclusion ratio = $200,000 ÷ $500,000 = 40%. If your monthly payment is $1,600, $640/month is tax-free return of investment, and $960/month is taxable.

Once you've recovered your full investment: If you outlive your life expectancy and have received $200,000 in tax-free basis, every subsequent payment is 100% taxable — the exclusion ratio drops to zero.

If you die before recovering your investment: The unrecovered basis is deductible on your final tax return (or by your estate).

LIFO Rule for Deferred Annuity Withdrawals

This rule catches many annuity owners by surprise. If you have a deferred annuity and take a partial withdrawal BEFORE annuitizing (before you start receiving regular annuity payments), the IRS assumes you're withdrawing earnings first.

How LIFO works: Your deferred annuity has $300,000 total value — $200,000 of basis (your premiums) and $100,000 of accumulated earnings. You withdraw $60,000. The IRS says: that $60,000 comes from the $100,000 of earnings first — 100% taxable. You must exhaust all the earnings before any tax-free basis comes out.

This is dramatically different from how mutual funds work (where you recover a pro-rata portion of basis on every redemption). It means that any partial withdrawal from a deferred annuity before annuitization is likely to be mostly or entirely taxable, plus potentially subject to the 10% penalty if you're under 59½.

After all earnings are distributed: Once you've withdrawn all the earnings (your basis exceeds total remaining value), subsequent withdrawals are tax-free basis recovery.

The 10% Early Distribution Penalty

Like IRAs and 401(k)s, nonqualified annuities impose a 10% additional tax on early distributions. The penalty applies to the taxable portion of withdrawals before age 59½.

Exceptions (§ 72(q)(2)):

Death: Distributions after the annuitant dies — no penalty
Disability: Annuitant becomes disabled (within the meaning of § 72(m)(7))
SEPP (Substantially Equal Periodic Payments): Series of equal payments over your life expectancy, calculated using IRS-approved methods (same as IRA § 72(t) SEPP rules)
Immediate annuity: Annuity contract purchased with a single premium that starts within 1 year — no penalty on the required distributions
Qualified funding asset: Annuity purchased to fund periodic payments from damage awards
Employer plan termination: Annuity held through a terminated employer plan

1035 Tax-Free Exchange

Section 1035 of the code allows you to exchange one annuity contract for another without triggering current tax — even if the old contract has large embedded gains. The tax basis carries over from the old contract to the new one.

Why you'd do it: Your old annuity has high fees, poor investment options, or you want different payout terms. A 1035 exchange lets you move to a better contract without paying tax on the accumulated earnings.

Rules: The exchange must be directly between insurance companies (or via a check made payable to the new carrier). You cannot take possession of the funds. You can exchange an annuity for another annuity, or convert an annuity to a life insurance policy under certain conditions. You cannot exchange a life insurance policy for an annuity tax-free under § 1035.

How It Affects You

If you're receiving annuity payments and get a Form 1099-R each year: Check Box 2a (Taxable Amount). Insurance companies typically compute the exclusion ratio correctly — but errors occur, and many filers don't know to check. The 1099-R will often show the taxable amount. Verify it against your own exclusion ratio calculation (investment ÷ expected return = tax-free percentage per payment). If your payments are $1,500/month and your exclusion ratio is 40%, your tax-free portion is $600/month ($7,200/year) — the 1099-R Box 2a should show $1,080/month ($12,960/year) as taxable, not the full $18,000. If Box 2a is blank or shows the full payment amount, you need to calculate the taxable portion yourself using the exclusion ratio — the insurer won't always do it for you. Keep a running tally of your recovered basis: once you've received back your full investment in the contract, every subsequent payment is 100% taxable.

If you have a deferred annuity and need money before you annuitize: The LIFO rule means every dollar you take out comes from earnings first — until all the growth is depleted, your basis stays untouched. Example: you invested $150,000 and it grew to $230,000. If you withdraw $25,000, the entire $25,000 is taxable (it comes from the $80,000 in earnings). If you're under 59½, add 10% penalty on the taxable portion ($2,500 penalty). This makes partial withdrawals from deferred annuities significantly more expensive than they appear. Alternatives to consider: a § 1035 exchange transfers your contract to a new insurer tax-free (preserving your basis); or a SEPP (substantially equal periodic payment) arrangement lets you take regular withdrawals before 59½ without the 10% penalty, but requires sticking to a calculated schedule for at least 5 years or until age 59½, whichever is later.

If you inherited a nonqualified annuity: Unlike inherited stocks or real estate, there is no step-up in basis on inherited annuities — the growth inside the contract is "income in respect of a decedent" (IRD) and remains fully taxable when the beneficiary receives it. If you inherited a $300,000 annuity where the deceased invested $180,000 (basis = $180,000, gain = $120,000), you'll owe ordinary income tax on the $120,000 in gains as you receive payments. You can spread the tax by taking distributions over your life expectancy (if you're a designated beneficiary) or you may be forced to take full distribution within 5 years. There is a federal estate tax deduction available for the IRD component if estate tax was paid on the annuity value — but confirm with a tax professional, as this deduction requires specific calculation.

If you're considering buying an annuity for retirement: The critical tax question is whether you're funding it with pre-tax (qualified) or after-tax (nonqualified) dollars. An annuity inside an IRA or 401(k) doesn't give you any additional tax deferral beyond what the IRA already provides — but you pay ongoing insurance company fees for features you don't gain extra tax benefit from. An annuity purchased with after-tax dollars does give you tax deferral on earnings (until withdrawal) and the favorable exclusion ratio when annuitized. But earnings inside a nonqualified annuity are taxed as ordinary income when withdrawn — not at favorable long-term capital gains rates. For most investors, maximizing 401(k) and IRA contributions first, then considering nonqualified annuities only for additional tax deferral, is the standard planning approach.

State Variations

Most states follow federal annuity taxation rules, but a few states offer additional exclusions or different treatment:

Pennsylvania: Pennsylvania does not tax pension and annuity income received by residents 60 or older. For PA residents, an annuity payout may be entirely state-tax-free regardless of the federal exclusion ratio.
States without income tax (Florida, Texas, Nevada, etc.): No state income tax on annuity payments regardless of taxability.
Most states conform to the federal exclusion ratio methodology for nonqualified annuities.

Pending Legislation

No major changes to § 72 annuity taxation are currently pending. SECURE 2.0 (2022) made several changes affecting qualified longevity annuity contracts (QLACs) — allowing larger QLAC investments within IRAs and deferring required minimum distributions to age 85. The general § 72 framework for nonqualified annuities is stable.

Recent Developments

The SECURE 2.0 Act (2022) updated the rules for QLACs inside qualified plans, expanding the maximum investment from $135,000 to $200,000 (indexed) and eliminating the prior 25%-of-account cap. Insurance company marketing of "FIAs" (fixed indexed annuities) and "RILAs" (registered index-linked annuities) has grown substantially — these products are governed by § 72 like traditional annuities, but their complex crediting mechanisms and surrender charge structures create practical tax complications when annuitants make early withdrawals.

OBBBA and annuity tax treatment — no major changes: The One Big Beautiful Bill Act did not include major modifications to nonqualified annuity tax treatment under § 72. The Act's retirement provisions focused primarily on expanding SECURE 2.0 Roth contribution rules and extending TCJA individual tax provisions — not annuity-specific reform. The annuity industry had lobbied for a "longevity annuity" tax incentive to promote annuitization of retirement savings; the provision was not included in OBBBA's final text.
DOL fiduciary rule and annuity sales — regulatory reversal: The Biden DOL issued a new fiduciary rule in 2024 extending fiduciary standards to annuity sales recommendations made by insurance agents. The rule would have required agents selling fixed indexed annuities (FIAs) and other insurance products to act in the client's "best interest" rather than merely meet a suitability standard. The Trump DOL withdrew the Biden fiduciary rule in early 2025, reverting to a more lenient suitability standard for annuity sales. Insurance industry groups (NAIFA, ACLI) supported withdrawal; consumer advocates argued the rollback allows higher-commission products to be sold over better alternatives.
QLAC maximum and RMD interaction: SECURE 2.0's increase in the QLAC maximum to $200,000 (indexed for inflation; approximately $205,000 in 2026) allows larger deferral of required minimum distributions from IRAs and qualified plans. QLACs must commence payments by age 85; the deferred RMD reduction is valuable for retirees who don't need income in their 70s but want longevity protection. IRS has issued guidance clarifying that QLAC payments do not reduce the exclusion ratio calculation for the remainder of the annuity — an important tax planning detail for retirees coordinating QLAC income with Social Security and other taxable income.
Inherited annuity — SECURE Act post-death taxation: The SECURE Act (2019) eliminated the "stretch" IRA for most non-spouse beneficiaries, replacing it with a 10-year distribution requirement. Non-qualified inherited annuities are governed by § 72(s) — which predates SECURE and has a different (but equally complex) distribution requirement framework. The interaction between § 72(s) annuity distribution rules and SECURE's retirement account rules creates significant estate planning complexity for beneficiaries who inherit both IRAs and non-qualified annuities from the same decedent. IRS has not issued clarifying guidance specifically addressing the SECURE/§ 72(s) intersection.
