How To Calculate Rmd On An Inherited Ira

Calculate your Required Minimum Distribution (RMD) for an inherited IRA based on IRS rules

Comprehensive Guide: How to Calculate RMD on an Inherited IRA

When you inherit an Individual Retirement Account (IRA), the IRS requires you to take minimum distributions each year, known as Required Minimum Distributions (RMDs). The rules for inherited IRAs changed significantly with the SECURE Act of 2019 and subsequent IRS guidance. This guide will walk you through everything you need to know about calculating RMDs for inherited IRAs.

Understanding Inherited IRA RMD Rules

The rules for inherited IRAs depend on several factors:

• Your relationship to the original account owner
• Whether the original owner had already started taking RMDs
• The year the original owner passed away
• Your age relative to the original owner

The 10-Year Rule (SECURE Act Changes)

The Setting Every Community Up for Retirement Enhancement (SECURE) Act, passed in December 2019, made significant changes to inherited IRA rules. For most non-spouse beneficiaries who inherit an IRA after December 31, 2019:

1. No annual RMDs required during the 10-year period
2. Full distribution required by the end of the 10th year after the original owner’s death
3. Exceptions apply for eligible designated beneficiaries (EDBs)

Beneficiary Type	Pre-SECURE Act Rules	Post-SECURE Act Rules (2020+)
Spouse	Could treat as own IRA or use life expectancy	Same as pre-SECURE Act
Minor child of account owner	Life expectancy stretch	Life expectancy until age of majority, then 10-year rule
Disabled or chronically ill individual	Life expectancy stretch	Life expectancy stretch
Individual not more than 10 years younger than account owner	Life expectancy stretch	Life expectancy stretch
Other non-spouse beneficiaries	Life expectancy stretch	10-year rule (full distribution by year 10)

Step-by-Step RMD Calculation Process

Calculating your RMD for an inherited IRA involves several steps. Here’s how to do it correctly:

1. Determine the applicable distribution period
   • For spouses: Can use their own life expectancy or the original owner’s
   • For non-spouses inheriting before 2020: Use Single Life Expectancy Table
   • For non-spouses inheriting after 2019: Generally subject to 10-year rule
2. Find the IRA balance
   • Use the fair market value as of December 31 of the previous year
   • Include all inherited IRAs from the same decedent (aggregate for calculation)
3. Calculate the RMD amount
   • Divide the IRA balance by the life expectancy factor
   • For the 10-year rule: No annual RMD, but must distribute entire balance by year 10
4. Take the distribution
   • Must be taken by December 31 of the distribution year
   • First RMD for inherited IRAs may have special timing rules

Life Expectancy Tables

The IRS provides three main tables for calculating RMDs:

1. Uniform Lifetime Table – Used by original IRA owners
   • Assumes a joint life expectancy with a beneficiary 10 years younger
   • Not typically used for inherited IRAs (except in specific spouse situations)
2. Single Life Expectancy Table – Used for most inherited IRAs
   • Based solely on the beneficiary’s age
   • Factor decreases by 1 each subsequent year
3. Joint Life and Last Survivor Table – Used when spouse is sole beneficiary and more than 10 years younger
   • Considers both spouses’ ages
   • Less common for inherited IRA calculations

Sample Single Life Expectancy Factors (from IRS Publication 590-B)

Age	Life Expectancy Factor	Age	Life Expectancy Factor
70	27.4	85	14.8
71	26.5	86	14.1
72	25.6	87	13.4
73	24.7	88	12.7
74	23.8	89	12.0
75	22.9	90	11.4
80	18.7	95	8.6
81	17.9	100	6.3
82	17.1	105	4.7
83	16.3	110	3.5
84	15.5	115	2.6

Special Cases and Exceptions

Several special situations can affect how you calculate RMDs for inherited IRAs:

• Multiple Beneficiaries: When an IRA has multiple beneficiaries, the RMD is typically calculated based on the oldest beneficiary’s life expectancy. Beneficiaries can split the account by December 31 of the year following the owner’s death to use their own life expectancies.
• Trust as Beneficiary: If a trust inherits the IRA, the RMD rules depend on whether the trust qualifies as a “see-through” trust and the ages of the trust beneficiaries.
• Minor Children: Under the SECURE Act, minor children can use the life expectancy method until they reach the age of majority (typically 18 or 21, depending on state law), after which the 10-year rule applies.
• Disabled or Chronically Ill Beneficiaries: These “eligible designated beneficiaries” can continue to use the life expectancy method even after the SECURE Act.
• Surviving Spouses: Have special options including treating the IRA as their own or rolling it over into their own IRA.

Common Mistakes to Avoid

Calculating RMDs for inherited IRAs can be complex, and errors can result in significant penalties. Here are common mistakes to avoid:

1. Missing the December 31 deadline: RMDs must be taken by December 31 each year (except for the first RMD in some cases). Missing this deadline results in a 50% penalty on the amount that should have been withdrawn.
2. Using the wrong life expectancy table: Using the Uniform Lifetime Table instead of the Single Life Expectancy Table for inherited IRAs will result in incorrect calculations.
3. Not accounting for multiple inherited IRAs: If you’ve inherited multiple IRAs from the same person, you must calculate the RMD for each account separately, but you can take the total distribution from any one or combination of the accounts.
4. Forgetting to reduce the life expectancy factor: For life expectancy calculations, you must subtract 1 from the factor each subsequent year.
5. Misapplying the 10-year rule: Many beneficiaries mistakenly believe they must take annual distributions under the 10-year rule, when in fact they only need to fully distribute the account by the end of the 10th year.
6. Not considering state laws: Some aspects like the age of majority for minor children can vary by state, affecting when the 10-year rule begins.

Tax Implications of Inherited IRA Distributions

Distributions from inherited IRAs are generally taxable income to the beneficiary, with some exceptions:

• Traditional IRAs: Distributions are taxed as ordinary income. If the original owner made non-deductible contributions, a portion of each distribution may be non-taxable.
• Roth IRAs: Distributions are typically tax-free if the account was open for at least 5 years. However, RMD rules still apply to inherited Roth IRAs.
• Tax Withholding: You can elect to have federal income tax withheld from your distributions. The default withholding rate is 10%, but you can choose a different percentage or opt out entirely.
• State Taxes: Some states don’t tax IRA distributions, while others tax them as ordinary income. Check your state’s specific rules.
• Estate Taxes: If the IRA was part of a large estate, there might be estate tax considerations, though this affects relatively few beneficiaries.

It’s often wise to work with a tax professional when taking distributions from inherited IRAs, especially for large accounts, to develop a tax-efficient distribution strategy.

Strategies for Managing Inherited IRA Distributions

If you’ve inherited an IRA, consider these strategies to optimize your tax situation and financial planning:

1. Spread out distributions: If subject to the 10-year rule, consider taking distributions over several years to manage your tax bracket rather than taking a large distribution in the final year.
2. Convert to Roth: If you’re a spousal beneficiary, you might consider converting the inherited IRA to a Roth IRA, paying taxes now to allow for tax-free growth (though this has specific rules and limitations).
3. Charitable distributions: If you’re charitably inclined and over age 70½, you might be able to make qualified charitable distributions (QCDs) from an inherited IRA to satisfy RMD requirements.
4. Coordinate with other income: Time your IRA distributions to coordinate with other income sources to minimize your overall tax burden.
5. Consider disclaiming: In some cases, it might make sense to disclaim (refuse) the inheritance, allowing it to pass to other beneficiaries who might be in lower tax brackets.
6. Invest wisely: While you can’t contribute to an inherited IRA, you can control how the remaining funds are invested based on your distribution timeline.

Recent Changes and Proposed Legislation

The rules for inherited IRAs have seen significant changes in recent years, and more may be coming:

• SECURE Act (2019): Eliminated the “stretch IRA” for most non-spouse beneficiaries, replacing it with the 10-year rule.
• SECURE Act 2.0 (2022): Made several adjustments to retirement account rules, though most changes didn’t directly affect inherited IRA RMDs. It did increase the RMD age for original owners to 73 (in 2023) and will increase it to 75 by 2033.
• Proposed IRS Regulations (2022): The IRS issued proposed regulations in February 2022 that would require annual RMDs in years 1-9 for beneficiaries subject to the 10-year rule if the original owner had already started RMDs. These regulations have been delayed and are not currently in effect, but may be finalized in the future.
• Potential Future Changes: There have been discussions in Congress about further modifying inherited IRA rules, possibly reinstating some form of stretch provisions or adjusting the 10-year rule.

Given the complexity and potential for future changes, it’s important to stay informed about the current rules and consider working with a financial advisor who specializes in retirement accounts.

Frequently Asked Questions About Inherited IRA RMDs

Q: Do I have to take an RMD from an inherited IRA every year?

A: It depends on when you inherited the IRA and your relationship to the original owner:

• For IRAs inherited before 2020: Generally yes, annual RMDs are required based on your life expectancy.
• For IRAs inherited in 2020 or later by non-spouse, non-EDBs: No annual RMDs, but the entire account must be distributed by the end of the 10th year after inheritance.
• For spouses and eligible designated beneficiaries: Annual RMDs are typically required based on life expectancy.

Q: What happens if I don’t take my RMD?

A: The penalty for missing an RMD is severe – 50% of the amount that should have been withdrawn. For example, if your RMD was $10,000 and you didn’t take it, you would owe a $5,000 penalty. The IRS may waive this penalty if you can show that the shortfall was due to reasonable error and that you’re taking steps to remedy it.

Q: Can I take more than the RMD amount?

A: Yes, you can always take distributions larger than the RMD amount. The RMD is simply the minimum you must withdraw each year (when annual RMDs apply). Taking larger distributions can help reduce future RMD amounts and potential tax burdens.

Q: How is the RMD calculated if there are multiple beneficiaries?

A: When multiple beneficiaries inherit an IRA, the RMD is typically calculated based on the oldest beneficiary’s life expectancy. However, beneficiaries can choose to split the IRA into separate accounts by December 31 of the year following the original owner’s death. After splitting, each beneficiary can use their own life expectancy for calculations.

Q: What if I inherited an IRA from someone who was already taking RMDs?

p>A: If the original owner had already started taking RMDs (i.e., had reached their required beginning date), different rules may apply:

• For non-spouse beneficiaries who inherited before 2020: Continue taking RMDs based on the original owner’s life expectancy (using their age in the year of death, reduced by 1 each subsequent year).
• For non-spouse beneficiaries who inherited in 2020 or later: The IRS has proposed (but not yet finalized) regulations that would require annual RMDs in years 1-9 if the original owner had already started RMDs, with full distribution by year 10.
• For spouses: Can generally treat the IRA as their own or continue RMDs based on the original owner’s life expectancy.

Q: Can I roll over an inherited IRA into my own IRA?

A: Only spouses can roll over an inherited IRA into their own IRA. Non-spouse beneficiaries cannot commingle inherited IRA assets with their own IRA assets. However, spouses have several options:

1. Treat it as their own IRA (by rolling it over or being the sole beneficiary)
2. Treat it as an inherited IRA (using their own life expectancy for RMDs)
3. Roll it over into an inherited IRA in their name

Non-spouse beneficiaries must keep the IRA as an inherited IRA and cannot roll it over into their own accounts.

Q: Are there any exceptions to the 10-year rule?

A: Yes, the following “eligible designated beneficiaries” (EDBs) are exempt from the 10-year rule and can use the life expectancy method:

• The surviving spouse of the IRA owner
• A child of the IRA owner who hasn’t reached the age of majority
• A disabled individual (as defined by IRS standards)
• A chronically ill individual (as defined by IRS standards)
• An individual not more than 10 years younger than the IRA owner

Note that for minor children, the life expectancy exception only applies until they reach the age of majority, after which the 10-year rule applies.
