When someone dies with a retirement account, the tax obligations that follow depend on who is named as beneficiary. In many cases, those obligations belong to the beneficiary, not the executor. When the estate itself is the named beneficiary, the executor takes on direct responsibilities. This guide covers key points for executors and beneficiaries to be aware of, including: the executor's role versus the beneficiary's role, beneficiary categories and how they determine the distribution rules, the 10-year rule and annual RMD requirements now in effect in 2026, the tax treatment of distributions from inherited traditional and Roth accounts, the filing forms involved (Form 1040, Form 1041), the penalties for missed required distributions, and more.
Key Takeaways
- Many inherited IRAs and 401(k)s pass directly to named beneficiaries outside probate, so tax obligations follow the beneficiary, not the executor.
- In 2026, non-eligible designated beneficiaries subject to the 10-year rule must take annual RMDs during years one through nine if the account owner had already begun taking distributions.
- Missing a yearly RMD triggers a 25% excise tax per missed distribution, though correcting within two years reduces the penalty to 10%.
- Whether the account owner died before or after their required beginning date determines which distribution rules apply.
- Tracking inherited account distribution windows and annual RMD deadlines gives executors and beneficiaries an organized picture to bring to their tax advisor.
The Executor's Role in Inherited Retirement Account Tax Obligations
When a decedent named a living beneficiary on an IRA or 401(k), those assets transfer directly to that beneficiary outside probate, and the tax obligations that follow belong to the beneficiary, not the executor.
That said, the executor's role is not entirely hands-off. The executor files the decedent's final Form 1040, which must account for any retirement distributions taken before death. If the estate itself is the named beneficiary, or if no beneficiary was designated, the account may fall into the probate estate, and the executor takes on direct administrative and tax responsibilities for it.
As the IRS notes in Publication 559, the personal representative is responsible for filing returns and paying any tax due on behalf of the decedent. Whether a retirement account passes to a named beneficiary or into the estate determines who owes what, a distinction covered further in the inherited IRA distribution rules.

How the SECURE Act and SECURE Act 2.0 Changed the Rules
Before 2020, most beneficiaries could stretch inherited IRA distributions across their own lifetime, spreading the tax burden over decades. The SECURE Act ended that for accounts inherited from owners who died after December 31, 2019.
The stretch IRA is gone for most beneficiaries. In its place, a 10-year rule applies: the inherited account must be fully distributed by the end of the tenth year following the account owner's death. As the IRS confirms, whether the account owner died before or after their required beginning date determines what rules apply to the beneficiary.
Starting in 2026, non-eligible designated beneficiaries subject to the 10-year rule must also take annual RMDs during years one through nine.
Beneficiary Categories
Which beneficiary category applies to an inherited retirement account determines the distribution rules, penalty exposure, and tax reporting path for that account.
| Beneficiary Category | Who Qualifies | Distribution Rule | Annual RMDs Required? |
|---|---|---|---|
| Eligible Designated Beneficiary (EDB) | Surviving spouses; minor children of the account owner; disabled or chronically ill individuals; beneficiaries no more than 10 years younger than the decedent | Stretch over own life expectancy (single life table) | Yes, based on life expectancy |
| Non-Eligible Designated Beneficiary | Named individuals who don't meet EDB criteria (e.g., adult children, siblings) | 10-year rule: full distribution by December 31 of year 10 | Yes, during years 1 through 9, if the owner died on or after their required beginning date; no annual RMDs if owner died before RBD |
| Non-Designated Beneficiary | Estates, charities, and many trusts | 5-year rule (if owner died before RBD) or owner's remaining life expectancy (if owner died on or after RBD) | Depends on applicable rule |
For the executor, locating retirement benefits after a death and identifying the correct category for each account is a key step before any distribution or filing decision can be made.
When the Estate Is the Named Beneficiary
When no individual beneficiary is named on a retirement account, the estate inherits it. The executor steps into the distribution role, and the income passes through the probate estate instead of going directly to an individual.
The applicable rules depend on whether the decedent had reached their required beginning date before death. If they had not, all funds must be distributed within five years. If they had, distributions follow the decedent's remaining life expectancy under the single life table.
Income from those distributions is reported on Form 1041, the estate's income tax return. As the IRS instructions for Form 1041 confirm, estates must report income generated during the administration period. Depending on whether distributions are passed through to beneficiaries via Schedule K-1, the tax liability may sit at the estate level or shift to individual heirs.
The 10-Year Rule and the Annual RMD Requirement in 2026
For non-eligible designated beneficiaries, the 10-year rule requires full distribution of the inherited account by December 31 of the tenth year following the account owner's death.
The critical variable is whether the original account owner had already reached their required beginning date before dying. If they had, beneficiaries subject to the 10-year rule must also take annual RMDs during years one through nine. If they had not, no annual withdrawals are required, and the full balance can be withdrawn at any point within the 10-year window.
In 2026, this annual RMD requirement is fully in effect. Beneficiaries who inherited accounts in 2020 or later from someone who had already begun taking RMDs are now several years into their distribution window with annual obligations attached. Missing any one of those yearly distributions triggers a 25% excise tax on the amount that should have been withdrawn, applied per year, per missed distribution.
Eligible Designated Beneficiary Options and the Spousal Exception
Eligible designated beneficiaries (EDBs) are not subject to the 10-year rule. Each of the five EDB categories can stretch distributions over their own life expectancy using the single life table instead.
The five EDB categories are:
- Surviving spouses
- Minor children of the decedent
- Disabled individuals, who must meet IRS definitions and retain supporting documentation as part of the estate record
- Chronically ill individuals, subject to the same IRS definition and documentation requirements
- Beneficiaries no more than 10 years younger than the decedent
The Surviving Spouse Exception
The surviving spouse holds the broadest flexibility of any beneficiary. A surviving spouse can treat the inherited IRA as their own by rolling it into an existing IRA or opening a new one, removing the account from inherited IRA distribution rules entirely. Distributions then follow the spouse's own age and retirement timeline.
A spouse who does not roll over the account can still use their own life expectancy for distributions, or delay RMDs until the year the decedent would have reached RMD age, whichever is later.
Minor children of the decedent hold EDB status only until they reach the age of majority. Once that threshold passes, the 10-year rule applies to the remaining balance.

How Elayne Helps Executors Track Inherited Retirement Account Deadlines
Inherited retirement account deadlines are easy to lose track of when an executor is simultaneously managing probate filings, creditor notices, and asset transfers. Elayne surfaces these obligations as part of its estate administration support, flagging distribution deadlines and annual RMD requirements.
For inherited accounts subject to the 10-year rule with mandatory annual withdrawals, Elayne tracks the distribution window and surfaces the deadlines attached to it, including the 25% penalty exposure that has been in effect since 2026 under SECURE Act 2.0. The executor and beneficiary can see what's due and when, and bring that organized picture to their tax advisor instead of reconstructing it from scratch.
FAQ
What are the executor tax obligations for inherited retirement accounts in 2026?
The executor's direct tax obligations for inherited retirement accounts are narrow in most cases: the final Form 1040 covers any retirement distributions the decedent took before death, and Form 1041 applies when the estate itself is the named beneficiary. When a living individual is named as beneficiary, the account passes outside probate and the tax obligations (including annual RMDs and the 25% penalty for missed distributions now in effect under SECURE Act 2.0) belong to the beneficiary, not the executor.
How does the 10-year rule for inherited retirement accounts work under SECURE Act 2.0?
The 10-year rule requires non-eligible designated beneficiaries to fully distribute an inherited IRA or 401(k) by December 31 of the tenth year following the account owner's death. Starting in 2026, beneficiaries whose account owner had already begun taking RMDs before death must also take annual distributions during years one through nine; they cannot simply wait and withdraw the full balance in year ten. Missing any yearly distribution triggers a 25% excise tax on the amount that should have been withdrawn, though SECURE Act 2.0 reduced the penalty from 50% and added a correction window that drops it further to 10% if the missed distribution is made within two years.
Inherited traditional IRA vs. inherited Roth IRA: what's the tax difference for beneficiaries?
Distributions from an inherited traditional IRA are taxed as ordinary income in the year received, which means a large withdrawal in a single year can push a beneficiary into a higher tax bracket. Qualified distributions from an inherited Roth IRA are income-tax-free, provided the account is at least five years old, because the original owner contributed after-tax dollars. Both account types are subject to the same 10-year distribution framework under SECURE Act 2.0.
