Inherited IRA RMD rules

How inherited IRA RMDs are calculated

The date of death of the original IRA owner and the type of beneficiary will determine what distribution method to use. You must take an RMD for the year of the IRA owner's death if the owner had an RMD obligation that wasn't satisfied.

For an inherited IRA received from a decedent who passed away on or after January 1, 2020:

Generally, a designated beneficiary is required to liquidate the account by the end of the 10th year following the year of death of the IRA owner (this is known as the 10-year rule). An RMD may be required in years 1–9 when the decedent had already begun taking RMDs. There are exceptions for certain eligible designated beneficiaries, defined by the IRS, as someone who is either:

• The IRA owner's spouse.
• The IRA owner's minor child.²
• An individual who is not more than 10 years younger than the IRA owner.
• Disabled (as defined by the IRS).
• Chronically ill (as defined by the IRS).

Generally, an eligible designated beneficiary may use the lifetime distribution rules that were in effect prior to 2020 and are specified in the "For an inherited IRA received from a decedent who passed away before January 1, 2020" section below.

You can calculate the RMD on your inherited IRA by using our online Inherited RMD Calculator. 

For more information, see IRS Publication 590-B, Distributions from Individual Retirement Arrangements (available at irs.gov).

Note: If the 10-year rule is being used for your inherited account, you should consult your tax advisor if you have any questions about taking distributions in accordance with this rule. A non-designated beneficiary (e.g., a non-individual such as an estate or charity) would generally be subject to the 5-year rule if the account owner died before they were required to begin taking RMDs (April 1 of the year following the year in which the owner reached RMD age).1 If the IRA owner passed away on or after April 1 of the year following the year in which the owner reached RMD age, the non-designated beneficiary would be subject to an RMD based on the original IRA owner's life expectancy factor. Special rules apply for certain types of trusts.

For an inherited IRA received from a decedent who passed away before January 1, 2020:

When a beneficiary becomes entitled to an IRA from an account owner who died before they were required to begin taking RMDs (April 1 of the year following the year in which the owner reached RMD age),¹ the beneficiary can choose one of two methods of distribution: over their lifetime or within 5 years (which is known as the 5-year rule).

Lifetime distribution

Spouse as sole primary beneficiary. If the owner's spouse chooses to take the IRA as a beneficiary rather than assume the account, they can choose when to begin taking RMDs on the basis of their own life expectancy. The spouse must begin taking RMDs by the later of December 31 of the year after the owner's death or December 31 of the year the owner would have reached RMD age.¹ The spousal beneficiary should not enroll in our RMD Service until the year they intend to begin taking RMDs. If the owner's spouse chooses to assume the IRA, they must begin taking RMDs by the later of December 31 of the year after the owner's death or April 1 of the year after the spouse reaches RMD age.¹

Non-spouse and when spouse is not sole primary beneficiary. An individual nonspouse beneficiary must begin taking RMDs on the basis of their own life expectancy by December 31 of the year after the owner's death. Multiple beneficiaries can take RMDs on the basis of their own life expectancies if all of the beneficiaries have established separate accounts by December 31 of the year after the owner's death and starting in that year. If all multiple beneficiaries have not established separate accounts by that December 31 date, all beneficiaries must take RMDs on the basis of the oldest beneficiary's life expectancy starting in the year after the owner's death.

5-year rule

Any individual beneficiary may elect to distribute the inherited IRA assets over the 5 years following the owner's death. The distribution must be completed by the end of the year containing the fifth anniversary of the owner's death. Any non-individual beneficiary—except for a qualified trust—must use the 5-year rule if the owner died before beginning to take RMDs.

Note: Vanguard's RMD Service doesn't accommodate accounts that are being distributed according to the 5-year rule. If you've elected, or are required, to use the 5-year rule for your inherited account, you should consult your tax advisor if you have any questions about taking distributions in accordance with this rule.

Inherited Roth IRAs and RMDs

Roth IRA owners don't need to take RMDs during their lifetimes, but beneficiaries who inherit Roth IRAs could have an annual RMD obligation. The requirement to distribute an annual amount can vary based on several factors (for example, the final age of the original IRA owner, the number of beneficiaries, etc.).
