Inherited IRA Planning — SECURE 2.0
The SECURE Act (2019) and SECURE 2.0 (2022) fundamentally changed inherited IRA rules. Most non-spouse beneficiaries are now subject to a mandatory 10-year distribution window — with annual RMDs required in years 1–9 if the original owner had reached RMD age. Misunderstanding these rules is one of the most common and costly errors in estate and retirement planning.
The SECURE Act Overhaul — What Changed and Why It Matters
Prior to the SECURE Act (effective January 1, 2020), most non-spouse beneficiaries could stretch inherited IRA distributions over their own life expectancy — a strategy known as the "stretch IRA." A 30-year-old beneficiary inheriting a $500,000 IRA could take small annual distributions over 50+ years, allowing the bulk of the account to continue growing tax-deferred.
The SECURE Act eliminated the stretch IRA for most beneficiaries. Non-eligible designated beneficiaries (non-EDBs) — which includes most adult children, grandchildren, and non-spouse beneficiaries — must now distribute the entire inherited IRA within 10 years of the original owner's death. There is no minimum annual distribution requirement under the original SECURE Act language, but the IRS's 2024 final regulations clarified that annual RMDs are required during years 1–9 if the original owner had already reached their required beginning date (RBD) at the time of death.
This distinction — whether the original owner died before or after their RBD — is the single most important factor in inherited IRA planning and the source of most practitioner errors since 2020.
Beneficiary Classification — The Decision Tree
The rules that apply to an inherited IRA depend entirely on the beneficiary's classification. There are three tiers:
| Beneficiary Type | Who Qualifies | Distribution Rule |
|---|---|---|
| Eligible Designated Beneficiary (EDB) | Surviving spouse; minor child of the deceased owner; disabled individual (§72(m)(7)); chronically ill individual; individual not more than 10 years younger than the deceased owner | Can use life expectancy (stretch) distributions — the old rules still apply |
| Non-Eligible Designated Beneficiary (Non-EDB) | Adult children, grandchildren, siblings, non-spouse beneficiaries who don't meet EDB criteria | 10-year rule — full distribution by December 31 of the 10th year after the owner's death; annual RMDs required in years 1–9 if owner died post-RBD |
| Non-Designated Beneficiary | Estate, charity, certain trusts without qualifying individual beneficiaries | 5-year rule (if owner died before RBD) or ghost life expectancy rule (if owner died post-RBD) |
The Pre-RBD vs. Post-RBD Distinction — The Most Critical Planning Factor
The required beginning date (RBD) is April 1 of the year following the year the owner turns 73 (for 2026). Whether the original owner died before or after their RBD determines whether annual RMDs are required during the 10-year distribution period for non-EDB beneficiaries.
| Scenario | Annual RMDs in Years 1–9? | Year 10 Requirement | Planning Implication |
|---|---|---|---|
| Owner died before RBD (before age 73) | No — beneficiary can take any amount in any year, including $0 | Full remaining balance must be distributed by Dec 31 of Year 10 | Maximum flexibility — beneficiary can defer all distributions to years 9–10 if bracket management supports it |
| Owner died after RBD (at or after age 73) | Yes — annual RMDs required in years 1–9 based on beneficiary's life expectancy from IRS tables | Full remaining balance must be distributed by Dec 31 of Year 10 | Less flexibility — annual RMDs create mandatory taxable income; planning focuses on bracket management around the required amounts |
Practitioner Example: The Year 10 Cliff
Client inherits a $400,000 traditional IRA from a parent who died at age 78 (post-RBD). Annual RMDs in years 1–9 are approximately $18,000–$25,000 per year based on the beneficiary's life expectancy factor. By year 10, the remaining balance — assuming 6% growth and annual RMDs taken — is approximately $280,000. The entire $280,000 must be distributed in year 10.
Planning action: If the client is in the 22% bracket during years 1–9 but expects to be in the 32% bracket in year 10 (due to other income), consider taking additional voluntary distributions in years 1–9 to reduce the year 10 cliff. Conversely, if the client expects to retire and drop to a lower bracket in year 10, minimizing distributions in earlier years may be optimal. The analysis requires a multi-year projection of the client's taxable income.
Surviving Spouse Options — The Most Powerful Planning Tool
A surviving spouse has more options than any other beneficiary type and should never default to the inherited IRA treatment without a full analysis of alternatives:
Roth Inherited IRA — The Hidden Advantage
Inherited Roth IRAs are subject to the same 10-year rule as inherited traditional IRAs for non-EDB beneficiaries. However, there is a critical difference: distributions from an inherited Roth IRA are generally tax-free (assuming the 5-year holding period has been met), and there are no annual RMD requirements during the 10-year period — even if the original owner died post-RBD.
This means a non-EDB beneficiary inheriting a Roth IRA can let the entire account grow tax-free for 10 years and then take the full distribution tax-free in year 10. The compounding effect is significant: a $200,000 inherited Roth IRA growing at 7% for 10 years becomes approximately $393,000 — all distributed tax-free.
This is one of the strongest arguments for Roth conversion planning during the original owner's lifetime — converting traditional IRA balances to Roth before death dramatically improves the after-tax value of the inheritance for non-spouse beneficiaries.
Tax Minimization Strategies Within the 10-Year Window
| Strategy | How It Works | Best For |
|---|---|---|
| Bracket-filling distributions | Take distributions each year up to the top of the current tax bracket (e.g., fill the 22% bracket before spilling into 24%) | Beneficiaries with variable income or who expect higher income in later years |
| Defer to low-income years | If the beneficiary expects a low-income year (sabbatical, business loss, retirement), concentrate distributions in that year | Self-employed beneficiaries with volatile income |
| Coordinate with other deductions | Time large distributions to years with large itemized deductions (medical expenses, charitable contributions, casualty losses) | Beneficiaries with significant deductible expenses in specific years |
| QCD from inherited IRA (age 70½+) | Beneficiaries age 70½ or older can make Qualified Charitable Distributions from an inherited IRA — up to $105,000 in 2026 — satisfying the RMD requirement tax-free | Charitably inclined beneficiaries age 70½+ |
| Disclaim to next-generation beneficiary | A beneficiary can disclaim the inherited IRA within 9 months of the owner's death, passing it to the contingent beneficiary — potentially a younger person with a longer distribution window or lower tax rate | High-income beneficiaries who don't need the funds and have lower-bracket children |
