She’ll Inherit Her Father’s $500,000 IRA at 54 and Plans to Leave It Alone Until Year 10. Because He Was Already Taking RMDs, the IRS Will Want a Withdrawal Every Year, and the Year-10 Balance Will Be Taxed on Top of Her Salary

A 54-year-old finance manager learns that her father named her the sole beneficiary of his $500,000 traditional IRA. She already has a plan. She will leave the account invested, let it grow tax-deferred for a decade, and take everything out in the final year, according to Internal Revenue Service.

The plan sounds disciplined, but it conflicts with IRS rules for inherited IRAs.

Her father was already taking required minimum distributions when he died. Because of that, the IRS expects a withdrawal from her inherited account every year, and whatever she holds back until the end gets added to her salary in one tax year.

Why the Ten-Year Rule Applies to Her

IRS Publication 590-B lists eligible designated beneficiaries. They get gentler treatment: a surviving spouse, the owner’s minor child, a disabled or chronically ill individual, or anyone not more than 10 years younger than the IRA owner. She is an adult daughter decades younger than her father, so she is a designated beneficiary who is not an eligible designated beneficiary.

For that group, the Internal Revenue Service requires the entire inherited balance to come out by December 31 of the year containing the 10th anniversary of the owner’s death. That deadline is fixed. What happens in the years before it depends on how old her father was when he died.

Her Father’s Required Beginning Date Sets the Rules

The yearly withdrawal requirement applies here only because her father had reached his required beginning date. For owners born on or after January 1, 1951, that date is tied to age 73 under Section 107 of the SECURE 2.0 Act.

Publication 590-B governs the outcome. When the owner dies on or after that date, it bases the beneficiary’s annual distributions on the longer of her own single life expectancy from Table I or her father’s remaining life expectancy. She takes those minimums every year inside the window, and whatever remains must come out by the ten-year deadline, but if he hadn’t taken his distribution for the year he died, she is responsible for taking that one too.

A parent who dies younger creates different rules. If the owner dies before the required beginning date then the ten-year rule applies, no distribution is required before the final year, according to Internal Revenue Service. A daughter in that position can leave the account untouched until the last year.

Final-Year Withdrawal Gets Stacked on Her Salary

Every dollar she withdraws from an inherited traditional IRA is taxed as ordinary income, at the same rates as her paycheck. The IRS says plainly that she can’t use the 10-year tax option or capital gain treatment. The lower capital gains rates that apply to a brokerage account have no bearing on this money.

Required minimums based on life expectancy are small slices of the account. If she takes only the minimum each year, most of the $500,000, plus a decade of growth, stays in the account until the deadline. That final withdrawal lands in her peak earning years, on top of a full salary.

Federal income tax is progressive. Each extra dollar is taxed at the rate of the bracket it lands in, and a large distribution added to wages pushes much of it into her highest marginal brackets. Spreading the same money across several years keeps more of it in lower brackets (the fix starts years before the deadline, which is the whole point of our free guide on defusing the first-year tax bomb: here).

Spreading Withdrawals Across the Window Costs Less

The required minimum is only the least she has to take. She can withdraw more in any year. Taking roughly even amounts across the window keeps each year’s added income smaller and reduces the share reaching her top bracket.

She can also time larger withdrawals to years with lower income, such as a job change, unpaid leave, or early retirement, while a year with a large bonus is the year to take only the minimum.

Steps That Lock In the Lower Tax Bill

• Put two questions to the custodian in writing: whether her father had reached his required beginning date, and whether he took his distribution for the year he died.
• Have the account set up as an inherited IRA in her father’s name for her benefit, so the ten-year clock and the annual minimums are tracked correctly.
• Mark the deadline: December 31 of the year containing the 10th anniversary of his death.
• Build a ten-year withdrawal schedule with a CPA, using her projected salary for each year, and update it every fall.
• Set federal and state withholding on each distribution so she doesn’t end up with an underpayment penalty.

The number to remember is $500,000. All of it will be taxed as ordinary income before the deadline, and the only thing she controls is how many tax years share that income.
