How Do I Calculate Rmd For Inherited Ira

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

Complete Guide: How to Calculate RMD for Inherited IRA

The rules for Required Minimum Distributions (RMDs) from inherited IRAs changed significantly with the SECURE Act of 2019 and subsequent IRS guidance. This comprehensive guide will walk you through everything you need to know about calculating RMDs for inherited IRAs, including the different rules that apply based on your relationship to the original account owner and when they passed away.

Understanding Inherited IRA RMD Rules

The IRS has specific rules for inherited IRAs that determine:

• Whether you need to take RMDs
• How much you must withdraw each year
• When you must take the distributions
• How long you can stretch the distributions

The rules depend primarily on:

1. Your relationship to the original IRA owner
2. Whether the original owner had already started taking RMDs
3. The date of the original owner’s death (before or after their required beginning date)
4. Whether you’re considered an “eligible designated beneficiary”

Key Changes from the SECURE Act

The Setting Every Community Up for Retirement Enhancement (SECURE) Act, passed in December 2019, made significant changes to inherited IRA rules:

Rule	Before SECURE Act	After SECURE Act
Stretch IRA for non-spouse beneficiaries	Could stretch distributions over life expectancy	Most must empty account within 10 years
Required beginning date for non-spouse beneficiaries	December 31 of year after death	December 31 of 10th year after death (for most)
Eligible Designated Beneficiaries	N/A	Special exceptions created (spouses, minor children, disabled, etc.)
RMDs during 10-year period	N/A	Proposed rules require annual RMDs if original owner died on or after RBD

Who is an Eligible Designated Beneficiary?

The SECURE Act created a special category called “Eligible Designated Beneficiaries” (EDBs) who can still use the stretch IRA rules. You qualify as an EDB if you are:

1. The surviving spouse of the IRA owner
2. A minor child of the IRA owner (until age of majority)
3. Disabled as defined by IRS rules
4. Chronically ill as defined by IRS rules
5. Not more than 10 years younger than the IRA owner

If you don’t fall into one of these categories, you’re subject to the 10-year rule.

RMD Rules Based on Your Relationship

Beneficiary Type	Original Owner Died Before RBD	Original Owner Died On/After RBD
Spouse	Can treat as own IRA or use life expectancy table. RMDs start when original owner would have turned 72 (or 73 if died after 2022)	Can treat as own IRA or use life expectancy table. RMDs continue as if original owner lived
Minor Child	Life expectancy until age of majority, then 10-year rule	Life expectancy until age of majority, then 10-year rule
Disabled/Chronically Ill	Life expectancy	Life expectancy
Not more than 10 years younger	Life expectancy	Life expectancy
Other Beneficiaries	10-year rule (must empty by end of 10th year after death)	10-year rule with annual RMDs (proposed rule)

Step-by-Step: How to Calculate Your Inherited IRA RMD

Follow these steps to calculate your RMD:

1. Determine the account balance as of December 31 of the previous year. This is your starting point for the calculation.
2. Identify your relationship to the original owner and whether you qualify as an Eligible Designated Beneficiary.
3. Determine the distribution period based on:
   • Your life expectancy (if using stretch rules)
   • The 10-year rule (if applicable)
   • The Single Life Expectancy Table (IRS Table I)
4. Calculate the RMD amount by dividing the account balance by the distribution period.
5. Check the deadline for taking the distribution (typically December 31 of the current year).

The 10-Year Rule Explained

For most non-spouse beneficiaries who inherited an IRA after December 31, 2019, the 10-year rule applies. This means:

• You must withdraw all funds from the inherited IRA by December 31 of the 10th year after the original owner’s death
• If the original owner died on or after their required beginning date (RBD), you must also take annual RMDs during years 1-9 (based on proposed IRS regulations)
• If the original owner died before their RBD, you don’t need to take annual RMDs but must empty the account by the end of year 10

Example: If the original owner died in 2022 at age 70 (before their RBD of 72), a non-spouse beneficiary would need to empty the account by December 31, 2032, but wouldn’t need to take annual RMDs during those 10 years.

Life Expectancy Tables

The IRS provides three life expectancy tables for RMD calculations:

1. Uniform Lifetime Table – Used by original IRA owners
2. Single Life Expectancy Table (Table I) – Used by most beneficiaries
3. Joint Life and Last Survivor Expectancy Table (Table II) – Used when the sole beneficiary is the owner’s spouse who is more than 10 years younger

For inherited IRAs, you’ll typically use the Single Life Expectancy Table (Table I). Each year, you’ll:

1. Find your age on the table
2. Use the corresponding life expectancy factor
3. Divide your December 31 balance by this factor
4. Subtract 1 from your life expectancy for the next year

Special Cases and Exceptions

Several special situations can affect your RMD calculations:

• Multiple Beneficiaries: If there are multiple beneficiaries, the account must be split by December 31 of the year after death to use individual life expectancies. Otherwise, the oldest beneficiary’s life expectancy is used.
• Trust as Beneficiary: If a trust is the beneficiary, the RMD rules depend on whether it’s a “see-through” trust and the identity of the trust beneficiaries.
• Missing Beneficiary Information: If the IRA custodian doesn’t have beneficiary information, the account may need to be distributed within 5 years.
• Roth IRAs: While original owners don’t have RMDs for Roth IRAs, beneficiaries do have RMD requirements for inherited Roth IRAs.

Penalties for Missing RMDs

The IRS imposes a severe penalty for missing RMDs or withdrawing less than the required amount:

• The penalty is 25% of the amount not withdrawn (reduced from 50% before 2023)
• The penalty can be reduced to 10% if corrected in a timely manner
• You must file Form 5329 to report the missed RMD and calculate the penalty
• You may request a waiver if you can show reasonable cause for the missed RMD

Example: If your RMD was $10,000 and you only withdrew $6,000, you would owe a penalty of $1,000 (25% of the $4,000 shortfall).

Strategies for Managing Inherited IRA RMDs

Consider these strategies to optimize your inherited IRA:

1. Spread out distributions: If subject to the 10-year rule without annual RMDs, consider spreading withdrawals evenly to manage tax impact.
2. Convert to Roth: If you’re a spousal beneficiary, consider converting to a Roth IRA to eliminate future RMDs (though you’ll pay taxes now).
3. Charitable distributions: If you’re charitably inclined and over 70½, you can make qualified charitable distributions (QCDs) to satisfy RMDs.
4. Tax planning: Coordinate withdrawals with other income to stay in lower tax brackets.
5. Disclaim inheritance: In some cases, disclaiming the inheritance (within 9 months) might be beneficial for estate planning.

Recent IRS Guidance and Proposed Regulations

The IRS issued proposed regulations in February 2022 that clarified several aspects of the SECURE Act changes:

• Confirmed that annual RMDs are required in years 1-9 for beneficiaries subject to the 10-year rule when the original owner died on or after their RBD
• Clarified that the 10-year rule applies to designated beneficiaries who are not EDBs
• Provided guidance on how to calculate RMDs when the original owner was already taking RMDs
• Addressed the treatment of trusts as beneficiaries

Note that these are proposed regulations, and final regulations may differ. The IRS has indicated that penalties won’t be assessed for 2021 and 2022 RMDs under the 10-year rule while waiting for final regulations.

Frequently Asked Questions

Q: Do I have to take RMDs from an inherited Roth IRA?
A: Yes, even though original owners don’t have RMDs for Roth IRAs, beneficiaries must take RMDs from inherited Roth IRAs.

Q: Can I roll over an inherited IRA into my own IRA?
A: Only spousal beneficiaries can roll over an inherited IRA into their own IRA. Other beneficiaries cannot combine inherited IRAs with their own.

Q: What if I inherit multiple IRAs?
A: You must calculate RMDs separately for each inherited IRA, though you can aggregate RMDs from multiple inherited IRAs from the same decedent if they’re the same type (traditional or Roth).

Q: Can I take more than the RMD?
A: Yes, you can always withdraw more than the RMD amount. The RMD is just the minimum you must withdraw.

Q: What happens if the original owner died before 2020?
A: If the original owner died before 2020, the old rules apply, and you can generally use the stretch IRA rules based on your life expectancy.

Q: Do I pay taxes on inherited IRA distributions?
A: Yes, distributions from inherited traditional IRAs are taxed as ordinary income. Inherited Roth IRA distributions are tax-free if the account was open for at least 5 years.

Working with a Financial Professional

Given the complexity of inherited IRA rules, especially with the recent changes from the SECURE Act, it’s often wise to consult with a financial advisor or tax professional who specializes in retirement accounts. They can help you:

• Determine the most tax-efficient withdrawal strategy
• Navigate the different rules based on your specific situation
• Understand the tax implications of your distributions
• Coordinate inherited IRA distributions with your overall financial plan
• Stay compliant with changing IRS regulations

When choosing a professional, look for someone with specific expertise in inherited IRAs and the SECURE Act changes. Consider credentials like Certified Financial Planner (CFP) or Enrolled Agent (EA) for tax-specific advice.

Final Thoughts

Calculating RMDs for inherited IRAs requires careful attention to the specific rules that apply to your situation. The SECURE Act made significant changes that eliminated the stretch IRA for most beneficiaries, replacing it with a 10-year distribution rule. However, there are still important exceptions for eligible designated beneficiaries.

Remember these key points:

• Your relationship to the original owner determines which rules apply
• The year of the original owner’s death (before or after their RBD) affects your RMD requirements
• Most non-spouse beneficiaries must empty inherited IRAs within 10 years
• Missing RMDs can result in substantial penalties
• Strategic planning can help minimize the tax impact of required distributions

Always verify your calculations and consult with a tax professional if you’re unsure about your specific situation. The IRS provides official tables and worksheets to help with RMD calculations, and our calculator above can give you a good estimate of your required distribution amount.
