Section 72: Annuity Taxation, 72(t) Penalty, and Exceptions

Internal Revenue Code Section 72 sets the distribution rules for annuities and retirement accounts: it decides how much of each payment is taxable, imposes a 10% additional tax on most withdrawals before age 59½, and controls when a plan loan turns into a taxable event. The taxable portion depends on whether you funded the account with pre-tax or after-tax dollars, and the 10% tax applies only to that taxable portion unless one of the statutory exceptions covers you.¹

Figuring the Taxable Portion of a Distribution

The first question with any withdrawal is how much of it counts as income. The answer turns on the account type.

Non-Qualified Annuities and the Exclusion Ratio

Payments from a non-qualified annuity are part return of your own money and part taxable income. Section 72 splits them using the exclusion ratio: your investment in the contract (the after-tax dollars you put in) divided by the expected return (the total you’re projected to receive based on IRS life expectancy tables).¹

If your investment in the contract is $120,000 and your expected return is $180,000, the ratio is 66.67%. On a $1,000 monthly payment, $666.70 is excluded and $333.30 is taxable. That split runs until you’ve recovered the full $120,000. From that point on, every dollar is fully taxable as ordinary income.

Traditional 401(k)s, 403(b)s, and Deductible IRAs

Pre-tax retirement accounts give you no basis, so every dollar you withdraw is ordinary income. There’s no ratio to calculate. Your plan administrator or IRA custodian reports the gross and taxable amounts on Form 1099-R.²

Traditional IRAs With Nondeductible Contributions

Nondeductible contributions create basis in a traditional IRA, but you can’t cherry-pick the tax-free dollars out. Every distribution is a proportional mix of taxable money and basis, using the ratio of your total basis to the combined value of all your traditional IRAs.³ You calculate the split on Form 8606, which you must file any year you take a distribution and have basis.⁴ The IRS aggregates every traditional IRA you own for this calculation, so isolating the after-tax dollars in a separate IRA won’t work. The IRS also doesn’t track your basis for you; that recordkeeping is on you.

Roth IRAs and the Ordering Rules

Roth distributions come out in a fixed order:

Regular contributions first, always tax-free and penalty-free.
Conversion and rollover amounts next. The converted principal is generally tax-free, but each conversion carries its own five-year clock for penalty purposes.
Earnings last, tax-free only if the distribution is qualified.

A distribution of earnings is qualified when you’re at least 59½ and at least five tax years have passed since your first Roth contribution to any Roth IRA. That five-year clock starts on January 1 of the year of your first contribution and never resets. Non-qualified earnings are taxed as ordinary income and may face the 10% penalty.⁵

Conversions run on a separate clock. Each conversion starts its own five-year period on January 1 of the conversion year, and pulling converted amounts out before that clock runs, if you’re under 59½, exposes the taxable portion of the conversion to the 10% penalty. Convert money in 2024, 2025, and 2026 and you have three separate clocks. The general five-year rule for earnings and the conversion-specific five-year rule for penalties are different rules doing different jobs.

Beneficiaries who inherit a Roth never owe the 10% penalty regardless of age, because post-death distributions are exempt.⁶ But the earnings five-year rule follows the account: if the original owner hadn’t held any Roth IRA for five tax years before death, earnings you withdraw remain taxable until that clock completes. Contributions and conversion amounts still come out tax-free.

The 10% Additional Tax Under Section 72(t)

Section 72(t) adds a 10% tax to any taxable distribution from a qualified retirement plan or IRA taken before age 59½.⁷ It hits only the taxable portion, not the gross amount. Withdraw $20,000 from a traditional IRA where $5,000 represents nondeductible basis, and the penalty applies to the $15,000 that’s included in income.

You report the additional tax on Form 5329.⁸ One trap: SIMPLE IRA withdrawals taken during the first two years of participation carry a 25% penalty, not 10%.⁹

Failed Rollovers

An indirect rollover, where money is paid to you rather than transferred custodian-to-custodian, has to land in another eligible retirement account within 60 days. Miss the window and the entire amount is a taxable distribution. Under 59½, add the 10% penalty.¹⁰

Self-certification under Revenue Procedure 2016-47 is available for qualifying reasons like hospitalization, a postal error, or the death of a family member. You give the receiving institution a model letter. It isn’t an automatic waiver; if the IRS later disagrees on audit, the taxes and penalties come back retroactively.¹⁰

Exceptions to the 10% Additional Tax

Section 72(t)(2) lists exceptions, and some apply to all retirement accounts, some only to employer plans, and some only to IRAs. Matching the exception to the account type matters.

Substantially Equal Periodic Payments (SEPP)

The 72(t) SEPP exception lets you take distributions at any age from either an employer plan or an IRA if you commit to a series of substantially equal periodic payments. Payments are calculated under one of three IRS-approved methods: required minimum distribution, fixed amortization, or fixed annuitization.¹¹

Once you start, you can’t modify the schedule until the later of five years or the date you turn 59½. Break the schedule and the IRS retroactively imposes the 10% penalty on every distribution you took under the arrangement, with interest for the deferral period.¹¹ Start at 45 and you’re locked in for close to 15 years.

Separation From Service After Age 55

Leave your job during or after the calendar year you turn 55 and distributions from that employer’s plan are penalty-free. This is the Rule of 55.⁶ Two catches. The exception covers only the plan at the employer you separated from, not IRAs or old employer plans. And rolling the money into an IRA after leaving destroys the exception, because IRAs don’t qualify. For qualified public safety employees, the age drops to 50, or 25 years of service if earlier.¹²

Disability and Terminal Illness

Distributions taken because you’re disabled are penalty-free from both employer plans and IRAs. The definition is strict: a doctor must determine that you can’t perform any substantial gainful activity because of a physical or mental condition that has lasted or is expected to last at least 12 months, or is expected to result in death.¹³

SECURE 2.0 added a separate terminal illness exception. A physician must certify that death is reasonably expected within 84 months, and the certification has to be in hand before or at the time of the distribution.

Divorce (QDRO)

Payments to an alternate payee from an employer plan under a Qualified Domestic Relations Order are exempt from the 10% penalty.⁶ IRAs don’t use QDROs. An IRA transfer in a divorce is tax-free between spouses, but when the receiving spouse later takes a distribution, the normal early-withdrawal rules apply based on their age.

Medical Expenses, Health Insurance, and Higher Education

Unreimbursed medical expenses above 7.5% of your adjusted gross income can be paid from any retirement account penalty-free, and you don’t have to itemize to use the exception; the threshold just sets the exempt amount.¹³

If you’ve collected unemployment for at least 12 consecutive weeks, IRA distributions used to pay health insurance premiums for you, your spouse, and dependents are penalty-free. This one covers IRAs only.⁶

IRA withdrawals for qualified higher education expenses are also penalty-free. Eligible costs include tuition, fees, books, supplies, and room and board if enrolled at least half-time, for you, your spouse, children, or grandchildren.⁵ IRAs only.

First-Time Homebuyer

You may withdraw up to $10,000 from an IRA over your lifetime for a first-time home purchase without penalty.⁵ Funds must be used for qualified acquisition costs within 120 days. “First-time” is generous: you qualify if you haven’t owned a home in the two-year period ending on the acquisition date. IRAs only.

Birth or Adoption

Within one year of a child’s birth or an adoption becoming final, you can withdraw up to $5,000 penalty-free from any eligible retirement account. Each parent can take up to $5,000 individually for the same child.¹² You may recontribute the amount to a retirement plan within three years.

SECURE 2.0 Additions

Emergency personal expenses: up to $1,000 per year for unforeseeable financial needs. If you don’t repay within three years, you can’t take another emergency withdrawal until the repayment is complete.¹⁴
Domestic abuse victims: within one year of the abuse, the lesser of $10,000 (indexed) or 50% of your vested balance, repayable within three years.¹⁴
Federally declared disasters: up to $22,000, with taxable income spread evenly over three years and recontribution allowed within three years as a tax-free rollover.¹⁵

Death and IRS Levy

Distributions to a beneficiary after the account owner’s death are always penalty-free, regardless of the beneficiary’s age.⁶ And if the IRS levies your retirement account to collect a tax debt, the resulting distribution is also exempt.¹³

When a Plan Loan Becomes a Distribution

Many 401(k)s let you borrow from your own account. Section 72(p) sets the rules, and breaking them turns the loan into a taxable distribution.

Dollar limit: the loan can’t exceed the lesser of $50,000 or the greater of half your vested balance or $10,000. The $50,000 cap is reduced by your highest outstanding loan balance during the previous year.¹³
Repayment: within five years, in substantially level payments made at least quarterly.¹³
Principal residence loans can extend beyond five years with a reasonable repayment schedule.

Default on the loan, leave your job with a balance outstanding, or otherwise break the terms, and the remaining balance becomes a deemed distribution. It’s reported on Form 1099-R and taxed as ordinary income that year. Under 59½ with no exception, the 10% penalty stacks on top.¹⁶

The 20% Withholding Trap on Indirect Rollovers

An eligible rollover distribution from an employer plan that isn’t sent directly to another plan or IRA is subject to a mandatory 20% federal withholding on the taxable amount, and you can’t opt out.¹⁷ The only way around it is a direct trustee-to-trustee transfer.

The practical problem: if your 401(k) cuts you a $100,000 check, you receive $80,000. To complete a tax-free rollover you still have to deposit the full $100,000 in the new account within 60 days, which means finding the missing $20,000 from another source. You get the withheld amount back when you file your return, but not before. Deposit only the $80,000 you received and the missing $20,000 becomes a taxable distribution, potentially with the 10% penalty on top.
