Single Life Expectancy Table
IDD: Joint Life Expectancy Table (Uniform Lifetime)
IDD: Joint Life Expectancy Table (Non-Spouse)
Select the appropriate IRS life expectancy table based on your relationship to the deceased and whether you are a spouse. [?] Use the Single Life Expectancy Table if you are a spouse beneficiary and not using the IDD rules, or if you are a non-spouse beneficiary. For the IDD rules, use the Joint Life Expectancy Table with your spouse. If you are a non-spouse beneficiary using IDD rules, use the Non-Spouse table.
An Inherited IRA RMD, or Required Minimum Distribution, is the minimum amount that beneficiaries must withdraw annually from an inherited Individual Retirement Arrangement (IRA). When someone passes away, their IRA is typically inherited by a designated beneficiary. The IRS mandates that these inherited accounts, like Traditional IRAs and Sep IRAs (but generally not Roth IRAs for the original owner's lifetime), must start distributing funds to the beneficiary after a certain period. The purpose is to ensure that tax-deferred retirement savings eventually generate taxable income for the government. Understanding how to calculate your Inherited IRA RMD is crucial for avoiding penalties and managing your inherited assets effectively.
Who Should Use This Calculator?
This calculator is designed for anyone who has inherited an IRA from a deceased relative or friend. This includes surviving spouses, children, grandchildren, or other designated beneficiaries. Whether you are a spousal beneficiary taking advantage of the stretch IRA rules or a non-spousal beneficiary navigating the complexities of the SECURE Act, this tool will help you determine your annual withdrawal obligations.
Common Misconceptions
Several common misunderstandings surround Inherited IRA RMDs. One frequent misconception is that beneficiaries can withdraw funds without any limitations. This is incorrect; the IRS requires mandatory withdrawals. Another is the belief that all inherited IRAs have the same distribution rules. The rules can differ significantly based on whether the beneficiary is a spouse, the deceased's age at death, and specific elections made by the beneficiary (like treating the inherited IRA as their own). Finally, many people mistakenly believe Roth IRAs are subject to RMDs for beneficiaries; while the original owner is exempt, beneficiaries of Roth IRAs generally are not required to take RMDs.
Inherited IRA RMD Formula and Mathematical Explanation
Calculating your annual Inherited IRA RMD is a straightforward process once you have the necessary information. The core formula relies on the account balance at the end of the previous year and a life expectancy factor provided by the IRS.
The RMD Formula
The fundamental formula to calculate the Required Minimum Distribution for an inherited IRA is:
Previous Year-End Account Balance: This is the total value of the inherited IRA as of December 31st of the year preceding the RMD year. For example, to calculate your 2024 RMD, you would use the balance as of December 31, 2023.
Life Expectancy Factor: This is a number provided by the IRS in specific tables. The table you use depends on your status as a beneficiary (spouse or non-spouse) and whether you are following the rules under the SECURE Act's Inheritance Distribution (IDD) provisions.
IRS Life Expectancy Tables
The IRS provides three primary tables relevant to beneficiaries:
Single Life Expectancy Table: Generally used by non-spouse beneficiaries or spouse beneficiaries who do not elect to treat the IRA as their own.
Uniform Lifetime Table: Used by IRA owners to calculate their own RMDs. Spouse beneficiaries who elect to treat the inherited IRA as their own can also use this table.
Joint Life and Last Survivor Expectancy Table: This table is used for a spouse beneficiary who chooses to treat the inherited IRA as their own AND whose age is not more than 10 years younger than the deceased owner. The calculator uses the "IDD: Joint Life Expectancy Table (Uniform Lifetime)" and "IDD: Joint Life Expectancy Table (Non-Spouse)" options to reflect common scenarios under current regulations. The "Single Life Expectancy Table" option is for beneficiaries who are not using the IDD rules or are non-spouse beneficiaries.

Practical Examples (Real-World Use Cases)
Example 1: Non-Spouse Beneficiary (SECURE Act Rules)
Sarah inherits her father's Traditional IRA. Her father passed away at age 70. Sarah is 45 years old and was named the sole beneficiary. The inherited IRA balance on December 31st of the previous year was $350,000. Sarah is using the Single Life Expectancy table, and her current factor for age 45 is 39.7.
Inputs:
Previous Year-End Balance: $350,000
Beneficiary Age: 45
Life Expectancy Factor: 39.7 (from Single Life Expectancy Table for age 45)
Calculation:
RMD = $350,000 / 39.7 = $8,816.12
Interpretation: Sarah must withdraw at least $8,816.12 from the inherited IRA by December 31st of the current year to avoid IRS penalties. She can withdraw more if she wishes.
Example 2: Spouse Beneficiary Electing to Treat as Own IRA
Mark inherits his wife's Traditional IRA. His wife was 68 when she passed away, and she had already started taking RMDs. Mark is 65. The inherited IRA balance on December 31st of the previous year was $600,000. Mark decides to treat the inherited IRA as his own and uses the IRS Uniform Lifetime Table. For age 65, the factor is 21.4.
Inputs:
Previous Year-End Balance: $600,000
Beneficiary Age: 65
Life Expectancy Factor: 21.4 (from Uniform Lifetime Table for age 65)
Calculation:
RMD = $600,000 / 21.4 = $28,037.38
Interpretation: Mark is required to withdraw at least $28,037.38 from the inherited IRA during the current year. By treating it as his own, he aligns the distribution schedule with his personal retirement needs.

Decision-Making Guidance
The calculated RMD is the *minimum* amount you must withdraw. You are always permitted to withdraw more than the RMD. Consider your financial needs, other income sources, and tax implications when deciding whether to take only the minimum or a larger amount. If you are a spouse beneficiary, carefully consider the implications of treating the inherited IRA as your own versus keeping it as a separate inherited account. Consulting with a financial advisor or tax professional is highly recommended for personalized strategies.
Key Factors That Affect Inherited IRA RMD Results
Several factors significantly influence the amount of your Required Minimum Distribution from an inherited IRA. Understanding these can help you better plan your withdrawals and financial future.
Account Balance: The most direct factor. A higher year-end account balance will naturally result in a higher RMD, assuming the life expectancy factor remains constant. Careful management and investment performance of the inherited IRA directly impact this balance.
Beneficiary's Age: As the beneficiary gets older, their life expectancy factor decreases (meaning they have fewer projected years left to live according to the IRS tables). A smaller divisor leads to a larger RMD. This is a fundamental aspect of the RMD calculation.
Life Expectancy Table Choice: The selection of the correct IRS table (Single Life, Uniform Lifetime, or Joint Life) is critical. Different tables yield different factors, directly impacting the RMD amount. Spouse beneficiaries have more choices, which can significantly alter their RMD obligations.
Original Owner's Age at Death (Indirectly): While the beneficiary's age is used for the factor, the original owner's RMD status at the time of death could influence which rules apply, especially concerning the deceased's own RMDs and the timing of distributions. The SECURE Act significantly changed rules related to the original owner's age.
Marital Status (for Spouses): A surviving spouse has options that can affect their RMD. They can choose to treat the inherited IRA as their own (using the Uniform Lifetime Table) or remain a beneficiary (typically using the Single Life Expectancy Table). This choice can lead to vastly different RMD amounts.
Investment Performance & Withdrawals: The growth rate of the investments within the inherited IRA affects the year-end balance. Conversely, taking withdrawals significantly larger than the RMD in a given year will reduce the balance and subsequently lower future RMDs. Market volatility plays a role here.
Beneficiary Type (Spouse vs. Non-Spouse): Non-spouse beneficiaries generally face stricter withdrawal timelines (often a 10-year rule for full distribution under the SECURE Act) and may have fewer options regarding the calculation tables compared to surviving spouses.
Tax implications: While not directly part of the RMD calculation formula, the taxability of the withdrawals (Traditional vs. Roth inheritance) heavily influences decisions about taking more than the minimum RMD. Higher earners might strategically take larger RMDs in lower-income years.
Frequently Asked Questions (FAQ)
Q1: What happens if I don't take my Inherited IRA RMD?
A: Failing to take the required minimum distribution can result in a significant penalty – typically 50% of the amount you should have withdrawn, less the amount you actually did withdraw. This penalty can be waived if you can demonstrate a reasonable error and take corrective action promptly.
Q2: Do beneficiaries of inherited Roth IRAs have to take RMDs?
A: Generally, no. Beneficiaries of inherited Roth IRAs are typically not required to take RMDs during their lifetime. However, the heirs of the Roth IRA beneficiary may be subject to withdrawal rules. It's crucial to confirm the specific rules with the custodian and review IRS guidelines.
Q3: Can a spouse beneficiary roll over the inherited IRA into their own IRA?
A: Yes, a surviving spouse has the option to roll over the inherited IRA into their own Traditional IRA or a Roth IRA (if eligible). They can also elect to treat the inherited IRA as their own, which can change the RMD calculation method and potentially allow for delayed distributions.
Q4: What is the 10-year rule for inherited IRAs?
A: Under the SECURE Act, most non-spouse beneficiaries must distribute the entire balance of an inherited IRA within 10 years following the death of the account owner. While RMDs are calculated annually based on life expectancy for these beneficiaries, the entire account must be depleted by the end of the 10th year. Some exceptions apply (e.g., for disabled or chronically ill beneficiaries, minor children).
Q5: How do I find the correct life expectancy factor?
A: You can find the relevant factors in IRS Publication 590-B, Distributions from Individual Retirement Arrangements (IRAs). The specific table used depends on your beneficiary status (spouse or non-spouse) and whether you are following the new IDD rules. Our calculator provides common options, but consulting the IRS publication or a financial professional is recommended for certainty.
Q6: Do I need to take an RMD in the same year the IRA owner dies?
A: Generally, the beneficiary does not need to take an RMD for the year of the original owner's death. The RMD requirement for the beneficiary typically begins the year *after* the owner's death. However, it's essential to verify this with the IRA custodian or a tax advisor.
Q7: Does the inherited IRA balance need to be reported on my taxes?
A: The account balance itself is not typically reported as income until you take distributions. However, the RMD withdrawals from a Traditional Inherited IRA are generally taxable income to the beneficiary in the year they are withdrawn. Roth Inherited IRA withdrawals are typically tax-free.
Q8: What if the previous year-end balance is zero?
A: If the account balance was zero on December 31st of the previous year, your RMD for the current year would technically be zero. However, ensure this is accurate and consult with the custodian, as it might indicate account closure or specific distribution events.
