What it means
Tax-deferred accounts such as traditional individual retirement accounts and 401(k) plans let contributions and investment growth escape tax until money is withdrawn. Left alone, a wealthy saver could simply never withdraw and pass the account on untaxed, so the rules force withdrawals to begin at a specified age.
Under current US rules that age is 73, rising to 75 in 2033. The calculation is mechanical rather than judgemental.
The account balance on 31 December of the previous year is divided by a life expectancy factor from a published table, and the result is the minimum that must come out during the current year. The factor falls each year as the account holder ages, so the required percentage of the balance steadily rises.
Not every retirement account is caught by the rule. Roth accounts do not require distributions during the original owner's lifetime, and someone still working past 73 can usually defer distributions from their current employer's plan, though not from old plans or personal accounts left behind at previous jobs.
The tax consequence is the part people underestimate. An RMD is ordinary taxable income, so a large one can push a retiree into a higher bracket, increase the taxable portion of state pension income and raise health insurance premiums that are calculated from income.
Planning ahead by drawing down earlier or converting to a Roth account can smooth that spike. The penalty for missing an RMD is severe by design.
Under current rules the shortfall attracts a 25% excise tax, reduced to 10% if the mistake is corrected promptly within the allowed window, which is far heavier than the ordinary income tax that would have been due.
In practice
Real-world examples.
Example
A retired engineer holds accounts with three different providers and takes his full RMD from just one of them. Because traditional individual retirement accounts may be aggregated for this purpose, the total withdrawn satisfies the requirement even though two accounts were untouched.
Example
A 76 year old with more income than she needs directs her entire $22,000 RMD straight to a registered charity as a qualified charitable distribution. The requirement is satisfied and the amount never appears in her taxable income at all.
Example
A financial planner notices a client will face a large RMD spike at 73 because almost all his savings sit in tax-deferred accounts. Over the six years beforehand the client converts a portion each year to a Roth account, paying tax at a lower rate now to avoid a much higher bracket later.
Think of it
“RMD is the minimum you must withdraw from retirement accounts-mandatory withdrawals.
Formula
Calculation
RMD = account balance on 31 December of the previous year / life expectancy factor for the account holder's age
A retiree turns 75 during the year and her traditional retirement account was worth $984,000 on 31 December of the previous year. The published uniform lifetime table gives a factor of 24.6 for age 75.
RMD = $984,000 / 24.6 = $40,000. That is the minimum she must withdraw during the year, roughly 4.1% of the opening balance, and she may of course take more.
If her marginal tax rate is 24%, the withdrawal adds $40,000 x 0.24 = $9,600 to her tax bill. If she withdrew only $10,000 and forgot the rest, the shortfall would be $40,000 - $10,000 = $30,000, attracting a penalty of $30,000 x 0.25 = $7,500, reduced to $30,000 x 0.10 = $3,000 if corrected inside the permitted correction window.Case study
Seen in the real world.
This is an illustrative and clearly fictional scenario. Wendell Hartley, an invented retiree in a hypothetical planning example, had accumulated about $1,400,000 across two old workplace plans and a personal retirement account, and had never touched any of them because his consulting income covered his costs comfortably.
At 73 the rules obliged him to begin withdrawing. In this fictional example his first RMD came to roughly $52,800, which stacked on top of his consulting income and pushed him into a higher tax bracket while also increasing the income-linked premiums he paid for health cover. The combined effect cost him several thousand dollars more than the tax on the withdrawal alone.
The illustrative point his adviser made afterwards was that the problem had been visible for a decade. Had Hartley drawn modest amounts from age 65, when his taxable income was lower, or converted steadily to a Roth account, the same money would have left the account at a materially lower average rate.
Watch out
Common mistakes.
- Assuming that money not needed for living costs can simply stay in the account indefinitely, when the rules force withdrawals regardless of need.
- Using the current balance rather than the 31 December closing balance from the previous year, which produces the wrong figure in any year the market has moved.
- Forgetting that an RMD is fully taxable income, and being surprised when it raises tax brackets and income-linked charges rather than just the tax on the withdrawal.
Questions
People also ask.
Does the money have to be spent once withdrawn?
No, it only has to leave the tax-deferred account, and it can be reinvested immediately in an ordinary taxable account.
Do Roth accounts have required minimum distributions?
Not for the original owner during their lifetime, which is one of the main planning advantages of the Roth structure.
What happens to RMDs after the account holder dies?
Beneficiaries face their own distribution rules, and most non-spouse beneficiaries must now empty an inherited account within ten years.
