She Inherited Her Father’s $250,000 Roth and Didn’t Touch It for Ten Years. It Grew to $400,000, and Every Dollar Came Out Tax-Free

Her father left her a $250,000 Roth IRA. Ten years later, when she withdrew it all, the balance had grown to $400,000, and every dollar came out tax-free. This outcome reflects rules that make an inherited Roth IRA the most valuable retirement account a person can leave behind, and one most beneficiaries misunderstand.

Two Rules That Only Make Sense Together

The SECURE Act, effective for deaths after December 31, 2019, requires most non-spouse beneficiaries to empty an inherited retirement account within ten years. The critical detail almost no one knows: whether annual withdrawals are required during those ten years depends entirely on whether the original owner had begun required minimum distributions in life.

Roth IRA owners face no lifetime RMDs. Because the deceased owner had no RMD in progress, an inherited Roth carries no annual withdrawal requirement during the ten-year window. The beneficiary can leave the entire balance untouched, let it compound tax-free, and take everything in year ten. Assuming annual withdrawals are mandatory forfeits the account’s single most valuable feature.

How an Inherited Traditional IRA Compares

An inherited traditional IRA produces the opposite result. Every dollar withdrawn is ordinary income, stacked on top of existing wages. Deferring until year ten collapses a decade of distributions into a single taxable event, often pushing the beneficiary into the top federal bracket and triggering state income tax on the same dollars. IRS final regulations issued in July 2024 and effective beginning in 2025 confirm that annual RMDs are in fact required in years one through nine for traditional IRA beneficiaries whose decedent had already passed their Required Beginning Date, a point many tax advisors initially got wrong.

An inherited Roth reverses the math entirely. Growth inside the account is never taxed, and qualified distributions are never taxed. Ten years of continued market exposure inside a tax shelter can produce results no taxable account can match. SPDR S&P 500 ETF Trust (NYSEARCA:SPY), a broad index fund tracking the S&P 500, returned roughly 320% on a total-return basis over the ten years through late 2026, illustrating the kind of compounding an untouched equity balance inside a tax-free wrapper could have achieved.

Five-Year Condition That Can Spoil It

The one requirement worth knowing carefully: the Roth five-year holding period. For a fully qualified, tax-free distribution on earnings, five tax years must have passed since the original owner first funded any Roth IRA. That clock does not restart at death. The original owner’s holding period carries over directly to the beneficiary.

If the deceased opened their first Roth recently, the beneficiary may need to wait out the remaining time before withdrawing earnings tax-free. Contributions and converted amounts generally come out without tax regardless. To confirm the starting year, the beneficiary should locate the original owner’s first Roth contribution or conversion on Form 5498 or custodian records.

Rules Around the Edges

Surviving spouses can roll an inherited Roth into their own account and treat it as always theirs. Eligible designated beneficiaries, including minor children, disabled or chronically ill individuals, and anyone not more than ten years younger than the deceased, can stretch distributions over life expectancy rather than ten years.

Missing the ten-year deadline triggers a 25% excise tax on undistributed amounts. That rate drops to 10% if the beneficiary corrects the shortfall and files IRS Form 5329 within the two-year correction window provided under SECURE 2.0. Worth noting: the IRS waivers that shielded missed annual RMDs for the 2021 through 2024 tax years have fully expired, so 2025 and later shortfalls carry the full 25% exposure with no administrative relief buffer. Non-spouse beneficiaries cannot contribute new money to an inherited Roth or roll it into their own IRA, and state tax treatment generally follows the federal framework.

Planning Implications for Owners and Heirs

For retirees, the pattern is clear: a Roth is generally the most tax-efficient account to leave heirs, while a traditional IRA is among the least. Drawing down traditional balances first at the owner’s tax rate leaves Roth balances to compound across generations. Roth conversions during life move dollars from the worse category to the better one, settling the tax bill at the owner’s rate, which is typically lower than the heir’s rate during peak earning years. In the opening example, the account was left untouched for the full ten-year window before a single tax-free dollar was withdrawn.

Editor’s note: This article was updated to reflect the approximately 320% total return (including reinvested dividends) for SPY over the decade through late 2026, replacing the prior price-only figure, and to note that IRS final regulations effective January 2025 confirmed annual RMDs are required in years one through nine for traditional IRA beneficiaries when the decedent had passed their Required Beginning Date, and that IRS penalty waivers covering missed distributions for 2021 through 2024 have fully expired.
