If you're over 73 or managing a retirement account inherited from someone who was, you've likely heard about Required Minimum Distributions (RMDs) and the penalties attached to them. These rules exist to ensure people don't indefinitely shelter money in tax-advantaged accounts—but the penalties for missing them can be steep. Here's what you need to know.
An RMD penalty is a tax assessed by the IRS when you fail to withdraw the full amount you're required to take from certain retirement accounts in a given year. The penalty applies to the shortfall—the difference between what you should have withdrawn and what you actually did.
The penalty is significant: historically, the IRS has assessed 25% of the amount you failed to withdraw, though this has been subject to change. Even withdrawing just slightly less than required triggers the penalty on the full shortfall amount. This isn't a small fee—it's a substantial tax hit on top of any income taxes you owe on the distribution itself.
Not everyone faces these rules. RMD requirements apply to:
Roth IRA owners during their lifetime are exempt—one of the key advantages of Roth accounts. However, beneficiaries of inherited Roth IRAs do have distribution requirements.
The actual financial impact depends on several factors:
| Factor | How It Affects the Penalty |
|---|---|
| Amount of shortfall | Penalty is calculated on the exact amount you failed to withdraw |
| Your account balance | Larger balances often mean larger RMDs and larger potential penalties |
| Type of account | Different account types have different RMD rules and timelines |
| Beneficiary status | Inherited accounts have different distribution periods and rules |
| IRS penalty relief | In rare cases, the IRS may waive or reduce penalties if you have reasonable cause |
The IRS calculates your RMD by dividing your account balance (as of December 31 of the prior year) by a life expectancy factor published in IRS tables. This means:
Missing even part of this amount triggers the penalty on the shortfall.
The RMD penalty isn't the only cost. When you finally do take the distribution:
These layered consequences make it clear why RMD compliance matters financially.
The IRS does recognize that mistakes happen. Reasonable cause exceptions may apply if you can demonstrate:
Filing Form 5329 (if you're self-filing) or working with a tax professional to request a penalty waiver is possible, though approval isn't guaranteed. The key is acting promptly when you discover a shortfall—delaying makes relief less likely.
Understanding RMD penalties is one thing; knowing whether they apply to you requires examining:
A qualified tax professional or financial advisor can review your specific accounts and circumstances to confirm your RMD obligations and help you avoid costly mistakes.
