What are required minimum distributions?

A required minimum distribution, commonly called an RMD, is the minimum amount you must withdraw from certain tax-advantaged retirement accounts each year once the applicable rules require distributions to begin.

📅

A required annual withdrawal

For covered accounts, you generally must withdraw at least the required amount by the applicable deadline. You can usually withdraw more than the minimum.

🧮

Based on account value and age

The calculation generally uses the previous December 31 account balance and an IRS life-expectancy factor, subject to account-specific rules.

🧾

Potentially taxable income

Traditional pre-tax withdrawals are generally taxable as ordinary income. Your actual tax treatment depends on the account and your circumstances.

Important distinction

An RMD is not the same as the amount you need to spend in retirement. It is a minimum distribution required by tax rules, even if you do not need the money for living expenses.

When withdrawals begin

At what age do RMDs start?

For many account owners, the applicable starting age depends on birth year. A workplace plan may also allow an eligible employee to delay RMDs until retirement.

🎂

Age 73 under current rules

Many people born in the applicable transition years must begin RMDs at age 73. Your required beginning date also depends on the type of account and, for certain workplace plans, whether you are still employed.

🗓️

Age 75 for later birth years

Under current law, the applicable age increases to 75 for individuals who reach age 74 after December 31, 2032. Check the rules that apply to your birth year and account.

Deadlines and account types

Key RMD rules to know

These are the practical rules that matter when planning withdrawals from your retirement accounts.

⏰

First RMD deadline

You can generally delay your first RMD until April 1 of the year after the year you reach the applicable age or, where allowed, retire. This is an option, not an extra distribution-free year.

📆

Subsequent deadlines

After the first distribution year, RMDs are generally due by December 31 each year. If you delay your first RMD, you may need to take two distributions in the following calendar year.

🏦

Multiple retirement accounts

Workplace plan RMDs generally must be calculated and withdrawn separately from each plan. Certain IRA RMDs can be aggregated across eligible IRAs, but not every account type can be combined.

👥

Inherited retirement accounts

Beneficiaries follow separate distribution rules. The applicable schedule can depend on the beneficiary's relationship to the account owner, the owner's date of death and other factors.

Do not assume every account can be combined.

Taking extra money from one 401(k) does not generally satisfy another 401(k)'s RMD. Ask each plan administrator which account-specific distribution requirements apply.

How the math works

How is an RMD calculated?

For many account owners, the calculation starts with the retirement account's balance at the end of the previous year and divides it by the applicable IRS distribution period.

General calculation
RMD = Prior year-end balance ÷ IRS divisor

The correct divisor depends on the applicable IRS table and your circumstances.

1. Find the prior year-end balance

Use the account balance on December 31 of the year before the distribution year, subject to applicable adjustments and special rules.

2. Select the correct IRS table

The Uniform Lifetime Table is commonly used. Different rules may apply if your spouse is your sole beneficiary and is more than 10 years younger, or if you are calculating a beneficiary's RMD.

3. Divide the balance by the divisor

The result is the basic minimum distribution estimate for that account. Your plan administrator or tax professional can confirm the required amount.

4. Confirm the deadline and withdrawal

Check the required deadline, how the plan processes distributions, and whether tax withholding should be elected.

Example using illustrative numbers

If an eligible account had a prior December 31 balance of $265,000 and the applicable IRS divisor were 26.5, the estimated RMD would be $10,000 ($265,000 ÷ 26.5). The divisor here is an illustration; verify the correct IRS factor for your situation.

Tax planning

How are RMDs taxed?

The tax impact depends on the type of account and the tax character of the distribution. An RMD can increase your taxable income in the year you receive it.

💵

Traditional pre-tax accounts

Withdrawals are generally included in ordinary income, except for any portion representing after-tax basis or another tax-free amount.

🌿

Designated Roth 401(k)

The original account owner generally has no lifetime RMDs for 2024 and later years. Beneficiaries can still have required distributions after the owner's death.

📊

Withholding and estimated taxes

RMDs may affect your federal tax bill and, depending on your circumstances, state taxes or other income-related thresholds. Review withholding with a tax professional.

Ways to prepare for the tax impact

  • Estimate your total taxable income before the end of the year.
  • Ask your plan administrator about distribution timing and withholding options.
  • Review whether other income sources may affect your tax bracket or Medicare-related costs.
  • Consider charitable distribution strategies only if you meet the relevant eligibility and account rules.
  • Do not skip an RMD because you do not need the cash; discuss tax planning alternatives with a qualified professional.
Tax treatment is not identical for every retirement account.

Qualified Roth distributions and amounts representing after-tax basis may receive different treatment. Confirm the tax character of your particular distribution before filing.

Avoid costly mistakes

What happens if you miss an RMD?

Failing to withdraw the required amount by the deadline can trigger an excise tax on the shortfall. The tax rules provide for a reduced rate in certain circumstances, and a further reduction may be available when a timely correction qualifies.

⚠️

Excise tax on the shortfall

The general excise tax is 25% of the amount not distributed as required. It may be reduced to 10% if the shortfall is corrected within the applicable correction window.

🛠️

Correct the issue promptly

If you missed a deadline, contact the plan administrator or custodian, take appropriate corrective action, and ask a tax professional about Form 5329 and whether reasonable-error relief is available.

Do not assume the penalty is automatic or that relief is guaranteed.

The facts, timing of correction and applicable IRS procedures matter. Review the current IRS instructions for Form 5329 before filing.

RMD checklist

  • List every retirement account that may be subject to RMD rules.
  • Confirm the applicable starting age and required beginning date.
  • Obtain each account's prior December 31 balance.
  • Use the correct IRS life-expectancy table and divisor.
  • Check whether account aggregation is allowed in your situation.
  • Schedule withdrawals early enough to meet the deadline.
  • Keep account statements and distribution confirmations for tax records.
Common questions

Required minimum distribution FAQs

Quick answers to common questions about RMD ages, deadlines, calculations and taxes.

At what age do required minimum distributions start?

For many account owners, the applicable starting age is 73 under current law. It becomes 75 for individuals who reach age 74 after December 31, 2032. The exact required beginning date can depend on birth year, account type, retirement status and plan terms.

Can I delay my first RMD until the following year?

Generally, yes. You may be able to delay your first RMD until April 1 of the year after the year you reach the applicable age or, for an eligible workplace plan, retire. You will generally need to take the next year's RMD by December 31 of that same year, potentially resulting in two distributions during one calendar year.

Are RMDs required from a Roth 401(k)?

The original owner of a designated Roth 401(k) generally does not have lifetime RMDs for 2024 and later years. After the owner's death, beneficiary distribution rules apply. A Roth IRA also has no lifetime RMDs for its original owner.

How do I calculate my RMD?

For many accounts, divide the prior December 31 balance by the applicable IRS life-expectancy divisor. The correct table can vary based on your situation. Beneficiary accounts and certain spouse-beneficiary situations may use different factors or schedules.

Can I combine RMDs from multiple accounts?

Some IRA RMDs may be aggregated across eligible IRAs. Workplace plan RMDs generally must be satisfied separately for each plan. Special account types have different rules, so confirm whether aggregation is permitted before taking a distribution.

Are required minimum distributions taxable?

Traditional pre-tax retirement distributions are generally included in taxable income, except for eligible tax-free amounts such as after-tax basis. Qualified Roth distributions can receive different treatment. Your individual tax outcome depends on your accounts and circumstances.

What is the penalty for missing an RMD?

The general excise tax is 25% of the shortfall. It may be reduced to 10% when the shortfall is corrected within the applicable correction window. Further relief may be available in qualifying cases; review current IRS instructions and consult a tax professional.

Can I reinvest my RMD instead of spending it?

Once you have taken the required distribution, you can generally choose what to do with the money outside the retirement account, subject to tax and investment considerations. You cannot simply leave the required amount inside the account and count it as withdrawn.

Do beneficiaries have to take RMDs?

Beneficiaries are subject to distribution rules, but the applicable schedule depends on the beneficiary category, account type, date of death and other circumstances. Inherited Roth accounts can also have beneficiary distribution requirements even though the original owner had no lifetime RMDs.
