Your Parents’ $300,000 House Is Tax-Free When You Inherit It. Their $300,000 IRA Could Cost You $72,000 or More, and Here’s Who Should Get Which

Two heirs, two $300,000 assets, two very different tax bills. The house arrives clean. The IRA arrives with the IRS as a silent co-beneficiary.

Here is the split the tax code creates, and the practical question every parent with both kinds of wealth should answer before writing anything down.

Same Dollar Value, Very Different After-Tax Value

An heir who inherits appreciated property takes a basis equal to the value at the date of death. That is the step-up. If your parents bought the house for $60,000 in 1985 and it is worth $300,000 today, the $240,000 of appreciation simply vanishes for income-tax purposes. A prompt sale at $300,000 produces little or no taxable gain.

For scale, the S&P Cotality Case-Shiller U.S. National Home Price Index sits at 337.3 as of July 2026, versus a January 2000 base of 100, so a great many family homes carry embedded gains that would be brutal without the step-up.

A traditional IRA gets no basis adjustment. The heir owes ordinary income tax on every dollar withdrawn, stacked on top of their own wages, under the ten-year distribution rule that applies to most non-spouse beneficiaries.

Where the $72,000 Comes From

Treat the headline as illustrative. Assume a 45-year-old heir already earning roughly $150,000, married filing jointly, inheriting a $300,000 traditional IRA in 2026. Under the SECURE Act’s ten-year rule, the full balance must be distributed by the end of the tenth year after death.

There is a critical wrinkle many heirs miss. If the original owner had already started required minimum distributions before dying, the IRS requires heirs to take annual withdrawals in each of the first nine years as well, not just empty the account by year ten. That rule, finalized by the IRS in July 2024 and enforced beginning in 2025, can compress the timing considerably.

Spread $300,000 evenly across ten years and each $30,000 withdrawal lands squarely in the 24% federal bracket on top of wages. Federal tax on the IRA distributions alone comes to about $72,000 before any state income tax. Concentrate the withdrawals into the final year and a chunk gets pushed into the 32% or 35% bracket, easily costing $90,000 or more.

The actual cost depends entirely on the heir’s own bracket in the years they withdraw. An heir in the 12% bracket might owe closer to $36,000 federal. A high-earning heir in the 35% bracket could owe $105,000. Same $300,000 IRA, wildly different net inheritance.

Match the Asset to the Heir

This is where estate planning earns its fee. Point the pretax IRA toward the lower-bracket heir, or toward a charity, which owes no income tax on it. Point the step-up assets toward the higher-bracket heirs.

Consider two adult children: one is a public-school teacher in the 12% bracket, the other is a surgeon in the 35% bracket. A 50/50 split of both assets feels fair but leaves real money on the table. The surgeon nets far less per dollar of IRA than the teacher would, yet both would net roughly the same after-tax value from the house.

Directing the IRA to the teacher and the house to the surgeon can preserve tens of thousands of dollars for the family without changing the headline dollar split at all. A charitable bequest of the IRA is even cleaner: the charity receives 100 cents on the dollar because it owes no income tax, and the estate may also qualify for a charitable deduction.

Roth, Beneficiary Forms, and the Ten-Year Clock

A Roth IRA changes the calculus. The ten-year clock still applies, but qualified withdrawals are not taxable. Because Roth owners have no required beginning date, heirs of an inherited Roth are generally not required to take annual withdrawals during the ten-year window, giving the account maximum time to compound tax-free. A $300,000 inherited Roth is closer in spirit to the inherited house than to the traditional IRA, and high-bracket heirs are excellent recipients of Roth dollars for exactly that reason.

One procedural point undoes more estate plans than any other: the beneficiary designation on the retirement account, not the will, controls who receives the IRA. A stale form naming an ex-spouse or a deceased sibling overrides every carefully drafted paragraph in the trust. Pull the beneficiary form on every IRA, 401(k), and annuity before the next holiday dinner (we put the full cleanup checklist, titling and beneficiary forms included, in a free estate guide here).

The Investment Side Still Matters

Taxes are half the story. With the 10-year Treasury yield at roughly 5.24% as of early October 2026, well above where it stood a year ago, an inherited IRA left invested for a decade continues to compound in a meaningfully higher-rate environment. The ten-year rule sets only the outer deadline; the withdrawal schedule inside it remains flexible. Timing distributions to low-income years, sabbaticals, gap years, or early retirement can shave the effective rate considerably.

Which parent should own which account, whether to convert some traditional dollars to Roth before death, and how to word the beneficiary form are decisions worth discussing once with a fiduciary advisor or CPA who can see the full balance sheet.

Editor’s note: This update corrects the index name from S&P CoreLogic Case-Shiller to S&P Cotality Case-Shiller (CoreLogic rebranded to Cotality in March 2025), refreshes the national home price index reading to 337.3 as of July 2026 and the 10-year Treasury yield to approximately 5.24% as of early October 2026, and adds the detail that heirs must take annual required minimum distributions in years 1 through 9 when the original IRA owner had already started RMDs before death, a rule the IRS began enforcing in 2025.
