Required minimum distributions from a traditional IRA now begin at age 73, not the age 70½ threshold that governed the rule for decades, or the age 72 threshold that briefly replaced it before Congress moved the line again. The current age applies to anyone who turns 73 before 2033, and it is not a permanent number: the same law that raised the threshold to 73 already schedules a second increase, to age 75, for savers who turn 74 after 2032. What actually triggers a penalty is missing the deadline attached to a specific birth year, not misremembering which age applies — and the IRS still measures that penalty as a percentage of the amount that should have come out of the account.
The age is set by birth year, and it is scheduled to move again
The current 73-year threshold traces to Section 107 of the SECURE 2.0 Act, which IRS Publication 590-B describes in exact statutory terms: the age is 73 for an account owner who turns 72 after December 31, 2022, and 73 before January 1, 2033, and it becomes 75 for anyone who turns 74 after December 31, 2032. That structure means a saver’s own birth year, not the calendar year in which they read the rule, determines which age governs their withdrawals — someone turning 73 in 2026 owes their first RMD under the current schedule, while someone roughly a decade younger will not face a required withdrawal until 75.
The distinction matters because the two prior versions of this rule are still circulating in outdated financial advice. Age 70½ applied before 2020, and age 72 applied to a narrow band of savers between the two SECURE Acts. An account owner relying on a decade-old article, a family member’s outdated experience, or an AI answer trained on stale data can misjudge their own required beginning date by a year or more, which changes the tax year in which the first withdrawal — and its income tax bill — actually lands.

The first required withdrawal carries a built-in timing trap
The IRS’s RMD FAQ page confirms that an account owner can delay the very first required withdrawal until April 1 of the year after they turn 73, rather than taking it by December 31 of the year they actually reach that age. That flexibility is often described as a benefit, but it has a cost most savers do not calculate in advance: the second RMD, for the following calendar year, is still due by that same December 31 — meaning a saver who defers the first withdrawal ends up taking two required distributions in a single tax year.
Stacking two RMDs into one year can push a retiree’s taxable income into a higher bracket, increase the portion of Social Security benefits subject to tax, or trigger higher Medicare Part B and Part D premiums through the income-related monthly adjustment two years later. None of those consequences are described on the account statement that simply reports the year’s required amount; they only surface when a saver compares the deferral option against taking the first withdrawal in the year it is actually due.
The penalty is calculable, and it depends on the account type as much as the age
An account owner who misses the deadline faces an excise tax of 25% of the amount that should have been withdrawn, reduced to 10% if the shortfall is corrected within two years — a penalty structure the IRS cut in half from the 50% rate that applied before 2023. The tax is reported on Form 5329, and the IRS allows the penalty to be waived entirely if the owner shows the shortfall was a reasonable error and that steps are being taken to fix it, which means a missed RMD is a correctable mistake, not an automatic loss.
The age 73 threshold also does not apply uniformly across every retirement account. IRS guidance on required minimum distributions confirms that Roth IRAs carry no RMD requirement at all during the original owner’s lifetime, even though the same owner’s traditional IRA is subject to the age 73 rule in the same tax year. A saver who calculates one required amount and assumes it covers every retirement account risks under-withdrawing from a second or third traditional account that must be calculated separately, even when the total can be taken from any combination of them.
The requirement to begin withdrawing at a fixed age, arriving on a schedule that itself keeps shifting later, sits awkwardly against a separate trend: Americans are living, and working, longer than the original 1986 rule anticipated when it set the threshold at 70½. Congress has responded twice in five years by pushing the age back rather than reconsidering the underlying premise that tax-deferred savings must eventually convert to taxable income. Until the 2033 shift to age 75 arrives, the operative fact for anyone approaching 73 remains the one the IRS states plainly: the deadline is tied to a specific birth year, and the deferral option that feels like relief in one December can double the tax bill in the following one.
