What is a Required Minimum Distribution (RMD)?

Summary

If you have money in a tax-deferred retirement account like a Traditional IRA, the IRS won't let it grow tax-deferred forever. At a certain age, you must begin withdrawing funds and pay taxes on them. These mandatory annual withdrawals are called required minimum distributions, and understanding how they work is essential for anyone approaching or already in retirement. This article covers which accounts are subject to minimum required distribution rules, when retirement account distributions must begin, how to calculate them, the penalties for falling short, and strategies to manage IRA withdrawal rules efficiently, including considerations for alternative assets like crypto and precious metals.

Understanding Required Minimum Distributions

A required minimum distribution (RMD) is the minimum amount you must withdraw annually from certain tax-deferred retirement accounts once you reach a specific age. The IRS mandates RMDs to ensure that money that grew tax-deferred is eventually taxed as ordinary income. As the IRS states, "RMDs are the minimum amounts you must withdraw from retirement accounts each year."

The logic behind RMDs is straightforward. When you contribute to a traditional retirement account, those contributions typically reduce your taxable income in the year they're made. The government defers collecting tax on that money, and its growth, until you withdraw it. RMDs are the mechanism the IRS uses to recapture that deferred tax revenue during your retirement years. As Reuters explains, RMD rules are designed to ensure tax-deferred savings are eventually taxed as income.

Which Retirement Accounts Require RMDs

Not every retirement account is subject to RMD rules. The distinction primarily comes down to whether contributions were made on a pre-tax or after-tax basis — and whether the account is a Roth owned by the original account holder.

Rmd Subject Vs Exempt Accounts

*Note: While Roth IRAs and designated Roth accounts are not subject to RMDs during the owner's lifetime, RMD rules do apply to beneficiaries who inherit these accounts.

One important point: self-directed IRAs follow the exact same RMD rules as any other traditional IRA. Whether your IRA holds stocks, cryptocurrencies, or precious metals, the IRS treats it identically for RMD purposes.

When to Start Taking RMDs and Important Deadlines

The age at which you must begin taking RMDs has changed in recent years thanks to new legislation. Currently, RMDs generally start at age 73. Under the SECURE Act 2.0, the starting age rises to 75 for individuals born on or after January 1, 1960, as Vanguard notes.

Birth Year	RMD Starting Age
1951–1959	73
1960 or later	75

Your first RMD is due by April 1 of the year after you reach the applicable age. However, this extended first-year deadline creates a potential trap: if you wait until April 1 to take your first RMD, you'll also need to take your second RMD by December 31 of that same calendar year, resulting in two taxable distributions in one year. After the first year, all subsequent RMDs are due by December 31.

Here's a simple timeline to keep in mind:

Reach your RMD age (73 or 75, depending on birth year)
Take your first RMD by April 1 of the following year
Take all subsequent RMDs by December 31 of each year

How to Calculate Your Required Minimum Distribution

Your RMD equals your prior-year account balance (as of December 31) divided by the applicable life expectancy factor from IRS tables. RMD amounts are based on your account balance and life expectancy, and for IRAs, the calculation always uses the prior December 31 balance.

The process breaks down into three steps:

Find your account balance as of December 31 of the prior year.
Look up your life expectancy factor in the appropriate table in IRS Publication 590-B.
Divide the balance by the factor. The result is your RMD for the current year.

The IRS provides two primary tables: the Uniform Lifetime Table, used by most account owners, and the Joint Life and Last Survivor Table, used when a spouse who is more than 10 years younger is the sole beneficiary.

Using IRS Life Expectancy Tables

The Uniform Lifetime Table is the default table for the vast majority of account holders. The factor decreases as you age, which means your required withdrawal percentage increases over time.

Age	Life Expectancy Factor
73	26.5
75	24.6
80	20.2
85	16.0
90	12.2

The Joint Life and Last Survivor Table applies only when your sole beneficiary is a spouse who is more than 10 years younger. Because this table produces a larger divisor, it results in a smaller annual RMD, effectively allowing more money to remain in the account and continue growing tax-deferred.

Example Calculation with $500,000 Account Balance

Let's say you're 73 years old and your traditional IRA balance was $500,000 as of December 31 of the prior year. Using the Uniform Lifetime Table factor of 26.5:

RMD = $500,000 ÷ 26.5 = approximately $18,868

Now consider the same $500,000 balance at age 80, where the factor drops to 20.2:

Age	Account Balance	Life Expectancy Factor	RMD
73	$500,000	26.5	~$18,868
80	$500,000	20.2	~$24,752

The difference illustrates how RMDs grow as you age, even if your account balance stays the same. In practice, your balance will fluctuate year to year based on market performance and prior withdrawals, so each year's RMD must be recalculated using the updated December 31 balance and the new age-based factor.

RMD Rules for Working Retirees

A common question among older workers is whether continued employment delays the RMD obligation. The answer depends on the type of account.

Traditional IRA owners must take RMDs starting at the applicable age regardless of employment status. There is no still-working exception for IRAs.

However, participants in employer-sponsored plans like 401(k)s can sometimes delay RMDs until the year they actually retire, provided the plan allows this exception. As Employee Fiduciary explains, for current employer plans, RMDs can sometimes wait until retirement if the plan permits the still-working exception.

There are two critical limitations to be aware of:

The still-working exception is not available to individuals who own 5% or more of the business sponsoring the plan.
The exception applies only to the plan of your current employer. Any 401(k)s or other plans from former employers remain subject to standard RMD rules on the normal schedule.

Tax Implications of Required Minimum Distributions

RMDs are generally taxed as ordinary income. The amount you withdraw is added to your adjusted gross income for the year and taxed at your marginal federal income tax rate.

Most distributions are subject to a default 10% federal income tax withholding, though you can elect a different withholding percentage or make estimated tax payments to avoid underpayment penalties at tax time. State income taxes may also apply, depending on where you live.

The downstream effects of RMDs can be significant. Larger distributions can:

Push you into a higher federal tax bracket
Increase Medicare Part B and Part D premiums through IRMAA surcharges
Make a greater portion of your Social Security benefits taxable

These cascading effects make proactive RMD planning essential, not just for the current year, but across your entire retirement horizon.

Penalties for Missing or Underwithdrawing RMDs

Failing to take the full RMD by the deadline triggers an IRS excise tax of 25% on the shortfall amount. This penalty was reduced from the historical 50% rate under the SECURE Act 2.0. If you correct the error within two years, the penalty may be further reduced to 10%.

To correct a missed RMD, you should withdraw the shortfall as soon as possible, file IRS Form 5329 with your tax return, and request a penalty waiver if the shortfall was due to reasonable cause.

Common mistakes to avoid:

Forgetting the first-year April 1 deadline and accidentally doubling up distributions in a single tax year
Failing to take separate distributions from employer plans. Unlike IRAs, 401(k) RMDs must generally be calculated and taken separately for each account.
Attempting to roll over an RMD. As the UC Net fact sheet notes, RMDs are not eligible for rollover to other tax-deferred accounts.

Strategies to Manage and Optimize RMDs

While RMDs are mandatory, the timing, source, and structure of your withdrawals are within your control. Smart planning can meaningfully reduce the tax impact of required distributions and help you manage retirement income more effectively.

The strategies below, Roth conversions, qualified charitable distributions, and multi-account management, each offer distinct advantages. As always, consult a tax advisor before implementing any strategy, since individual circumstances vary.

Roth Conversions and Tax Planning

By converting traditional IRA or 401(k) assets to a Roth IRA, you pay income tax on the converted amount now but eliminate future RMDs on those assets. Since Roth IRAs are exempt from RMDs during the owner's lifetime, this can substantially reduce your mandatory withdrawal burden in later years.

A phased conversion strategy, spreading conversions across multiple lower-income years between retirement and age 73, for example, lets you stay within a target tax bracket while gradually shifting assets out of RMD-subject accounts. Keep in mind that you cannot convert your RMD amount itself; the RMD must be taken first in any year you plan a conversion.

Qualified Charitable Distributions and Timing

A qualified charitable distribution (QCD) is a direct transfer of up to $105,000 per year (2024 limit, adjusted for inflation) from a traditional IRA to a qualifying charity. The amount counts toward your RMD but is excluded from your adjusted gross income, making it one of the most tax-efficient ways to give.

QCDs are available starting at age 70½, which is before the RMD starting age. Charitably inclined retirees can begin using QCDs early to reduce the account balance that will eventually be subject to RMDs. The key requirement is that the distribution must go directly from your IRA custodian to the charity, you cannot receive the funds first and then donate them.

Using Multiple Accounts to Meet RMD Requirements

If you own multiple traditional IRAs, you calculate the RMD for each one individually but may withdraw the total from any one or combination of your traditional IRAs. This aggregation rule gives you flexibility to choose which account to draw from based on asset performance, tax-lot considerations, or liquidity needs.

Employer-sponsored plans work differently. RMDs from one plan do not satisfy the RMD requirement for another plan. Each 401(k), 403(b), or 457(b) requires its own separate distribution.

This distinction is especially important for retirees with both IRAs and old employer plans, and it offers a strategic advantage for self-directed IRA holders who may want to take their aggregated IRA RMD from a more liquid account while leaving alternative assets untouched.

Managing RMDs with Alternative Assets in Self-Directed IRAs

The same IRS RMD rules that apply to any traditional IRA also apply to self-directed IRAs, but the practical execution can differ when the account holds assets like cryptocurrencies or precious metals. Deadlines, calculation methods, and required amounts don't change, but meeting those requirements with illiquid or volatile holdings requires additional planning.

The core challenge is that RMDs generally require a cash distribution. If your self-directed IRA holds Bitcoin, Ethereum, or physical gold, those assets may need to be liquidated to generate the cash needed to satisfy your RMD. Timing matters, especially with volatile assets where values can shift meaningfully in a short window.

Frequently Asked Questions

What is a required minimum distribution and why is it important?

A required minimum distribution is the smallest amount you must withdraw each year from tax-deferred retirement accounts like traditional IRAs and 401(k)s once you reach the applicable age. RMDs are important because they ensure previously untaxed retirement savings are eventually subject to income tax. Failing to take them can result in a 25% IRS penalty on the shortfall.

Can I delay taking RMDs if I am still working?

If you have a traditional IRA, you must begin RMDs at the required age regardless of employment status. However, if you participate in a 401(k) or other employer-sponsored plan at your current job, you may delay RMDs until the year you retire, unless you own 5% or more of the business.

How are RMDs calculated each year?

Your RMD is calculated by dividing your retirement account balance as of December 31 of the prior year by a life expectancy factor from IRS Publication 590-B. The factor decreases as you age, which means your required withdrawal amount generally increases over time.

What happens if I miss my RMD deadline?

If you fail to take the full RMD by the deadline, the IRS may impose a 25% excise tax on the amount you should have withdrawn. This penalty can be reduced to 10% if you correct the shortfall within two years and file IRS Form 5329.

Will the RMD starting age change in the future?

Yes. Under the SECURE Act 2.0, the RMD starting age is set to increase to 75 for individuals born in 1960 or later. This phased increase reflects longer life expectancies and gives retirees additional years of tax-deferred growth before mandatory withdrawals begin.
