Determine Required Minimum Distributions from IRA and 401(k) accounts for age 73+.
What is a Required Minimum Distribution (RMD)?
A Required Minimum Distribution (RMD) is the mandatory minimum amount the IRS requires you to withdraw each year from tax-deferred retirement savings. Because these accounts allow you to grow assets tax-deferred for decades, the government mandates annual withdrawals to collect ordinary income taxes. Consequently, our free RMD Calculator is designed to calculate your exact withdrawal obligations and help protect your retirement savings from steep penalties.
RMDs act solely as a statutory minimum floor. You are always permitted to withdraw more than the mandatory amount if your retirement living expenses demand it. However, excess distributions taken in a single year do not reduce your mandatory distribution obligations for future tax years.
Important RMD Dates and Age Milestones
Retirement legislation has shifted several times over recent years, modifying the starting age threshold for mandatory withdrawals:
- Age 73: Effective currently, you must initiate your first distribution by April 1 of the calendar year following the year you turn 73. This milestone was established by the passage of the SECURE Act 2.0 in December 2022.
- Age 75: The starting age is scheduled to increase further to 75 in the year 2033.
- Prior Law: Before 2019, the mandatory starting age was 70½, which was subsequently raised to 72 under the original SECURE Act of 2019.
⚠️ The Double-Taxation Trap of Delaying Your First RMD
The IRS allows you to defer your very first RMD until April 1 of the year after you reach age 73. However, if you choose this deferral, you must still withdraw your second RMD by December 31 of that same calendar year. Forcing two sizable RMD withdrawals into a single tax year creates two distinct taxable events, which can inadvertently push you into a significantly higher federal income tax bracket.
How RMDs Are Calculated
Calculating your mandatory withdrawal uses a straightforward mathematical formula, though manual tracking across several accounts can prove cumbersome. The core formula operates as follows:
📐 RMD Calculation Formula
RMD = Prior Year Account Balance (as of Dec 31) / IRS Life Expectancy Factor
Choosing the Correct IRS Life Expectancy Table
Your family structure dictates which of the IRS tables from Publication 590-B you must apply:
- Uniform Lifetime Table: Applied by most retirees, including those who are single, married to a spouse less than 10 years younger, or married to a spouse who is not their sole beneficiary.
- Joint Life and Last Survivor Expectancy Table: Used exclusively if your spouse is more than 10 years younger than you and serves as your sole account beneficiary. This table yields smaller mandatory distributions, preserving capital longer.
IRS Uniform Lifetime Divisors (Ages 73–80)
| Age (as of Dec 31) | IRS Divisor Factor | Mandatory Distribution Rate (%) |
|---|---|---|
| 73 | 26.5 | 3.77% |
| 74 | 25.5 | 3.92% |
| 75 | 24.6 | 4.07% |
| 76 | 23.7 | 4.22% |
| 77 | 22.9 | 4.37% |
| 78 | 22.0 | 4.55% |
| 79 | 21.1 | 4.74% |
| 80 | 20.2 | 4.95% |
What Retirement Accounts Do RMD Rules Apply To?
RMD guidelines govern most tax-advantaged, employer-sponsored, and defined-contribution plans. These include:
Eligible Retirement Accounts
- Traditional IRAs & Rollover IRAs
- SEP IRAs & SIMPLE IRAs
- Traditional 401(k) plans
- Most 403(b) and 457(b) plans
- Qualified Variable Annuities (held in an IRA)
- Profit-sharing plans
Key Roth IRA Exception
A major benefit of a Roth IRA is that it does not impose RMDs during the original owner’s lifetime. Because Roth IRAs are funded with after-tax dollars, your assets can remain untouched and grow tax-free indefinitely.
Rules for Combining and Consolidating RMDs
If you possess multiple tax-advantaged accounts, you must calculate the RMD for each account individually. However, how you physically withdraw those funds depends on the specific account types:
- Traditional IRAs: You must calculate your RMDs separately for each IRA. However, you can aggregate the total amount and withdraw it entirely from a single traditional IRA or across multiple traditional IRAs.
- 401(k) Plans: You must calculate and withdraw the designated RMD separately from each individual 401(k) plan. Aggregation is not allowed.
- 403(b) Accounts: You must calculate your RMDs separately, but you can sum the total and distribute it from one or more of your 403(b) plans.
- Inherited Retirement Accounts: Accounts inherited from different decedents cannot be consolidated. They must be calculated and distributed independently.
What Happens If You Fail to Take an RMD?
Because these distributions are mandatory, the IRS enforces strict penalties for non-compliance. Prior to recent legislative reforms, missing an RMD triggered a massive 50% penalty tax. Fortunately, under the SECURE Act 2.0, the penalty was lowered to 25% of the undistributed shortfall. If you correct the error within a two-year correction window, the penalty drops further to 10%.
While the year-end deadline of December 31 is absolute, the IRS does not require you to take distributions on a fixed monthly schedule. You retain full control over whether to withdraw your RMD as a lump sum, in monthly installments, or quarterly, provided you meet your annual target by the end of the year.
How Inherited IRAs and 401(k) RMDs Work
Inheriting a retirement plan initiates distinct distribution rules based on your relationship to the original account owner:
The Ten-Year Distribution Rule
Following the passage of the SECURE Act of 2019, most non-spouse beneficiaries are no longer allowed to “stretch” distributions over their lifetimes. Instead, they must withdraw the entire balance of the inherited account within ten years of the original owner’s death.
However, the law exempts “Eligible Designated Beneficiaries” from this ten-year depletion schedule, allowing them to stretch distributions over their own life expectancies:
- Surviving spouses.
- Minor children of the original account owner (up until they reach adulthood).
- Disabled or chronically ill individuals.
- Beneficiaries who are less than ten years younger than the deceased account owner.
Spousal Inheritance Exceptions
Surviving spouses have the greatest amount of flexibility. They can treat the inherited account as their own by performing a direct rollover, meaning RMD requirements will only align with their own age. Alternatively, spouses can roll the funds into an Inherited IRA, allowing them to:
- Delay RMDs until December 31 of the calendar year after their spouse’s death if the deceased spouse had already reached age 72 or 73.
- Delay RMDs until the calendar year in which the deceased spouse would have reached their corresponding mandatory RMD age.

💡 Strategies to Minimize Taxes on RMDs
- Execute Qualified Charitable Distributions (QCDs): If you are age 70½ or older, you can transfer up to $105,000 annually from a traditional IRA directly to a qualified charity. This donation counts toward your annual RMD and reduces your adjusted gross income (AGI) because the transfer is excluded from your taxable income.
- Leverage the “Still Working” Exception: If you continue working past age 73 and do not own more than 5% of the employing company, you can delay RMDs from your active employer-sponsored retirement plan. However, you must still take RMDs from all of your personal traditional IRAs and plans sponsored by former employers.
- Verify Custodial Calculations: The IRS mandates that brokerages and trustees offer to calculate your RMDs. However, the taxpayer is ultimately held liable for mistakes. Using our independent RMD Calculator helps you double-check custodian figures.
- Plan Roth Rollovers: While Roth 401(k) plans historically came with RMD guidelines, you can roll them over directly to a Roth IRA, completely bypassing lifetime withdrawal mandates.
