Americans turning 73 in 2026 face a new deadline that did not exist a few years ago: they must begin pulling money out of tax-deferred retirement accounts or face steep IRS penalties. The required minimum distribution age, which sat at 72 before Congress acted, now stands at 73 and will climb to 75 in 2033. That extended timeline gives savers additional years of tax-deferred growth, but it also compresses larger withdrawals into a shorter window later in life, raising the tax stakes for millions of account holders.
How the Age-73 RMD Rule Changes Retirement Tax Planning
The shift to age 73 traces directly to SECURE 2.0, enacted as Division T of the Consolidated Appropriations Act, 2023, through H.R. 2617 in the 117th Congress. Section 107 of that law raised the required beginning date for distributions, and the IRS has since updated its guidance to reflect the change. According to IRS RMD FAQs, the first required minimum distribution applies for the year a person reaches age 73, and the deadline to take that initial withdrawal is April 1 of the following year. Every subsequent annual distribution is generally due by Dec. 31.
That April 1 grace period creates a specific trap. Anyone who delays the first withdrawal into the next calendar year will owe two RMDs in a single tax year: the delayed first distribution plus the regular annual one. The IRS has published concrete examples illustrating this two-RMD-in-one-year pitfall, and the resulting income spike can push retirees into a higher tax bracket, increase Medicare premium surcharges, and trigger taxation of Social Security benefits that would otherwise remain untaxed.
The rule applies beyond traditional IRAs. According to Publication 571, the April 1 deadline also covers 403(b) tax-sheltered annuity plans for people who reached age 72 after Dec. 31, 2022. Some employer-sponsored plans allow participants who are still working to delay RMDs until the later of age 73 or actual retirement, a distinction that matters for teachers, hospital workers, and other employees in 403(b)-eligible roles. Plan documents and HR departments, not just IRS rules, determine whether this “still working” exception is available.
IRS Guidance and the 2033 Shift to Age 75
The second phase of the change arrives in 2033, when the RMD starting age rises again to 75 under SECURE 2.0 Act Section 107. That means someone born in 1960 could wait two additional years compared to someone born just a year earlier. The extra deferral time sounds like a clear benefit, but the math cuts both ways. Larger account balances at age 75 generate larger forced withdrawals, and those distributions land on top of Social Security income and any other earnings in the same tax year.
The hypothesis that post-2033 retirees will show measurably higher year-one taxable income compared to earlier cohorts is plausible on paper, since longer deferral periods allow balances to grow before the first mandatory withdrawal. But no IRS dataset or Treasury projection currently quantifies how much additional tax revenue this timing shift will generate or how sharply it will alter retiree tax brackets. For now, the effect remains a planning concern rather than a documented outcome.
What is clear from existing IRS tables is that required distributions are calculated by dividing the prior year-end account balance by a life-expectancy factor. When the first RMD is delayed from 73 to 75, the account balance has more years to grow, while the applicable life-expectancy factor at 75 is smaller than it would have been at 73. That combination mechanically produces a larger first withdrawal, even if the underlying investment returns are modest.
Planning Around Compressed Withdrawal Windows
For people approaching 73 in 2026, the immediate question is whether to take the first RMD in the year they turn 73 or delay it until the following year. Taking the distribution in the year it is first required avoids stacking two withdrawals into a single tax year, but it accelerates income slightly. Delaying can make sense for someone whose income will drop sharply the next year, such as a late-career worker planning to retire at 73, but it demands careful projections of tax brackets, Medicare surcharges, and the taxation of Social Security benefits.
The looming shift to age 75 adds another layer for younger savers. Those in their 50s and early 60s may want to consider partial Roth conversions or strategic withdrawals in their 60s and early 70s, intentionally drawing down pre-tax balances before RMDs begin. That can smooth taxable income over more years instead of allowing large pre-tax accounts to compound untouched until a later, more compressed withdrawal period.
Advisers also warn that the new timetable interacts with estate planning. Larger pre-tax balances left to heirs are now generally subject to a 10-year payout window for most non-spouse beneficiaries, which can create significant tax bills for adult children in their peak earning years. By contrast, gradually reducing pre-tax balances during the original owner’s lifetime-within manageable tax brackets-can leave heirs with a more flexible mix of taxable, tax-deferred, and tax-free assets.
For Americans turning 73 in 2026, the core message is not simply that RMDs start later, but that timing choices now can ripple through the rest of retirement. Understanding the April 1 deadline, the risk of doubling up distributions, and the coming age-75 threshold gives retirees a chance to shape their tax profile, rather than letting the calendar make the decision for them.
