A Missed Required Minimum Distribution Needs a Shortfall and Correction-Year File

The shortfall is separate from ordinary distribution income

Failure to take a required minimum distribution can create an excise tax on the shortfall. The current framework generally uses a 25% rate, potentially reduced to 10% when the failure is corrected within the applicable correction window and required conditions are satisfied. A waiver for reasonable error may be available when the taxpayer takes reasonable steps to remedy the shortfall. An owner should therefore establish the actual required amount, payment deadline, and correction facts before calculating a penalty. Continuing to work does not necessarily defer RMDs for a more-than-5% owner, and IRA rules differ from employer-plan rules. This guide addresses an established missed requirement rather than deciding whether a working owner qualifies for deferral. Taking money late can correct the distribution shortage, but it does not by itself eliminate Form 5329 reporting or establish waiver eligibility.

Measure the unpaid amount and the assumed rate

Assume an owner was required to receive $40,000 for a year but actually received only $28,000 counted toward that requirement. The shortfall is $12,000. At the general 25% excise-tax rate, that corresponds to $3,000 before relief. If the conditions for the 10% correction rate are met, the illustrative tax is $1,200. A supported waiver could produce a different result. Those figures do not decide the applicable rate or grant relief. The owner must establish the correction window, when the missing $12,000 was paid, and any required return filing. A subsequent year's normal RMD is a separate obligation, so the owner should not assume one $12,000 payment satisfies both the earlier shortage and the later year's full requirement. Regular income-tax treatment of the actual distributions also requires separate reporting.

Reconcile every account and payment deadline

Collect prior year-end balances, beneficiary and age information, applicable tables, plan statements, custodian calculations, distribution confirmations, and any first-year deferral choice. Review whether aggregation is permitted for the specific account types; IRA aggregation rules should not be casually applied across separate employer plans. Identify rollovers, withheld amounts, and payments that do or do not count toward the requirement. A Roth employer account or IRA may have different current rules, so do not include or exclude it solely from an old worksheet. Preserve the employer ownership facts relevant to any working-owner exception. If the required amount supplied by a provider is wrong, document the corrected calculation and who received the original instructions. The file should establish the shortfall without relying only on the owner's memory of bank deposits.

Correct promptly and document any relief request

Arrange the missing distribution using the appropriate account and obtain confirmation of the actual payment date. Review the current Form 5329 instructions for reporting the failure, reduced-rate conditions, and a reasonable-error waiver request. Provide a factual explanation, including what caused the error, when it was discovered, corrective steps, and changes preventing repetition. Do not claim that a provider mistake automatically guarantees waiver or reduced tax. Preserve correspondence and the submitted form. If several years or accounts are affected, calculate each separately rather than using one combined current-year amount. A return extension does not generally extend the original RMD payment deadline. The owner should also reserve regular income tax on the late payment and the current year's distributions, which can concentrate taxable income in the correction year.

Create an annual distribution confirmation control

Assign a person to verify required amounts early, confirm payment instructions, and check completed distributions before the deadline. Maintain a backup process if the owner is ill or a provider changes. A recurring bank instruction should be reviewed when balances, tables, account types, or ownership facts change. The practical result is a corrected shortfall with supported excise-tax reporting and an annual control that checks actual receipt. It is not an assurance that taking the missing money whenever convenient removes every consequence. Keeping the calculation and relief evidence together allows the owner to explain both the original failure and the remedy, while preventing a correction payment from obscuring the next year's independent required distribution.

Track the corrective payment and the current-year required payment as separate rows with separate deadlines. That prevents a custodian’s single annual total from concealing a remaining obligation after the earlier shortfall was repaired.
