Nearly 1 in 15 investors over age 73 missed their required minimum distribution in 2024, costing the investment community $1.7 billion in penalties. That’s the shocking statistic: not that required minimum distributions exist, but that despite decades of rules and accessible information, millions of Americans still fail to take them on time—and the financial cost is staggering. A Vanguard analysis found that 6.7 percent of account holders at RMD age forgot or missed their yearly withdrawal, triggering automatic penalties from the IRS.
The magnitude becomes personal when you look at the math. With an average RMD of $11,600 and a current penalty rate of 25 percent, a single missed withdrawal costs an investor roughly $2,900 in taxes owed to the government—money that never goes toward retirement living, healthcare, or anything else the retiree planned for. This isn’t theoretical. Across hundreds of thousands of retirement accounts, these missed withdrawals add up to penalties that dwarf the losses from many market downturns or investment mistakes.

Why 6.7% of Investors Still Miss RMD Deadlines
The December 31 deadline is straightforward, yet it remains the single most missed financial deadline in retirement planning. Unlike a mortgage payment or credit card bill that arrives with a clear notice, RMDs require the account holder to initiate the withdrawal themselves. Many investors simply forget. Others confuse the rules for different account types—IRAs, 401(k)s, and inherited accounts all have slightly different RMD mechanics—and make withdrawals from the wrong account in the wrong amount.
Complexity breeds mistakes. A married couple might not know that each spouse’s accounts require separate RMDs, or that a surviving spouse inheriting a 401(k) faces different rules than inheriting an IRA. Life changes compound the problem: people who move, change financial institutions, or go through a divorce often lose track of accounts that still require annual distributions. One divorced investor realized in March that her ex-spouse had transferred custodianship of a retirement account to a new firm, and her deadline had quietly passed in December while the account sat in limbo during the transfer.
The 25 Percent Penalty and How It Compounds
The IRS reduced the RMD penalty from 50 percent to 25 percent in 2023, a change that reflected pressure from retirement advocates and advisors. Even at 25 percent, the penalty is punitive. If an investor with a $50,000 IRA misses the deadline and fails to withdraw the full amount owed, they owe the IRS 25 percent of whatever they didn’t take out—before any income tax is factored in. That’s on top of the income tax they’ll eventually owe on the money anyway.
The real damage emerges when the mistake is discovered late. An investor might miss the December 31 deadline, not realize it until tax-filing time in April or later, and then file an amended return with penalties already accrued. The IRS does offer relief: if a shortfall is corrected within two years and Form 5329 is filed, the penalty drops to just 10 percent. But this requires the investor to act quickly and understand the filing requirements. Many people who discover the mistake years later face the full 25 percent penalty with no way to reduce it after the fact.
Who Gets Hit the Hardest
Ironically, wealthy investors with multiple accounts face the highest absolute penalty amounts. Someone with $500,000 across several IRAs, a rollover 401(k), and inherited accounts might owe RMDs totaling $40,000 or more in a given year. A missed withdrawal on that scale could result in a $10,000 penalty before any other tax consequences.
Smaller investors with a single IRA are statistically more likely to miss the deadline—many own fewer accounts and underestimate the complexity—but the absolute dollar impact is less severe. Older retirees face a different trap: cognitive decline or health crises can make deadline management impossible. An 85-year-old hospitalized in November might have a family member forget to arrange the year-end withdrawal, or the senior’s own deteriorating faculties might cause them to miss the deadline entirely. The IRS has waived penalties in some of these cases when families show reasonable cause, but the burden falls on the account holder or their heirs to prove it.
The Mechanics of Calculating Your Actual RMD
The IRS publishes a uniform lifetime table that determines how much must be withdrawn each year based on age and account balance. At age 73, the distribution period is 26.5, meaning you divide your December 31 balance from the prior year by 26.5 to get the RMD. At age 85, that period shrinks to 15.5. This table applies to most people, but exceptions exist: a spouse who is more than 10 years younger than the account owner uses a different table, and inherited IRAs follow completely different rules depending on the original owner’s age and the inheritor’s relationship to them.
Many investors hire financial advisors to calculate RMDs precisely because the rules branch into different scenarios. But not everyone has an advisor, and even those who do sometimes encounter surprises. A Roth IRA owner might assume they have no RMD during their lifetime (true), but fail to recognize that their beneficiary faces RMDs starting the year after their death. An investor who rolled a 401(k) into an IRA might forget that they still have a pension, which also requires a separate RMD. Each missed piece triggers its own 25 percent penalty.
What “Reasonable Cause” Waiver Actually Requires
The IRS can waive the RMD penalty entirely if an account holder shows reasonable cause and corrects the shortfall promptly. In practice, this means filing Form 5329 and attaching a statement explaining why the deadline was missed. The agency has granted waivers for serious illness, the death of a spouse or dependent, a spouse’s incapacity, or circumstances beyond the account holder’s control—such as a financial institution’s error in processing the withdrawal request. However, “forgetfulness” and “confusion about the rules” are not considered reasonable cause in most cases.
The IRS expects adults to manage their financial obligations, and a penalty is the consequence of neglect. There is no blanket waiver for people who simply did not remember the December 31 deadline. An investor who misses the deadline, immediately corrects it in January, and files Form 5329 with a valid reason might see the penalty eliminated entirely, but they must act within the window and present a defensible explanation. Many people never file the form at all, accepting the penalty as a sunk cost rather than attempting to fight it.
The Real-World Impact on Spouses and Inheritors
When a married couple uses a spousal election to determine the RMD—where the younger spouse’s age is used to calculate distributions—both must understand the mechanics. If the older spouse dies, the RMD rules change dramatically for the survivor. A widow who inherits a large IRA must take an RMD based on the IRS uniform table using her own age, and if she misses the deadline that year, the 25 percent penalty applies immediately, regardless of her grief or the chaos of managing the estate.
Inherited IRAs create a separate penalty trap for beneficiaries. The child or grandchild who inherits a parent’s IRA must take annual RMDs, but many beneficiaries are unaware of this requirement, especially if the account was not titled clearly or the parent died before explaining the inherited account’s tax implications. A 35-year-old who inherits their parent’s $200,000 IRA might take the lump sum they’re entitled to, unaware that they could have spread withdrawals over 10 years under current rules—and completely unaware that they owe an annual RMD based on their age. The first missed deadline costs them thousands in penalties.
Strategies to Prevent Missing an RMD Deadline
The most reliable method is to set up automatic distributions from the financial institution that holds the retirement account. Rather than waiting to calculate and withdraw the RMD manually, an investor can instruct their bank or brokerage to transfer the required amount automatically every year, with the money arriving well before December 31. This eliminates the calendar risk and the calculation burden.
A financial advisor or the institution’s customer service can help set this up, and it typically costs nothing. For those who prefer manual control or have multiple accounts, the key is to create a written checklist of all retirement accounts—including IRAs, 401(k)s, inherited accounts, and pensions—and to calculate the RMD for each one by mid-December. Many financial institutions send a summary in November showing the RMD calculation, and some send reminders automatically. An investor who received a reminder in November 2024, calculated their RMD as $11,600, and scheduled a withdrawal for December 15 would have avoided the 6.7 percent miss rate that created $1.7 billion in penalties across the industry.
