8.2 Required Minimum Distribution (RMD) Rules Under SECURE 2.0

Required Minimum Distribution (RMD) Rules Under SECURE 2.0

The statutory architecture of qualified retirement plans and individual retirement arrangements is designed by Congress to incentivize personal savings for retirement, not to facilitate perpetual, tax-subsidized wealth transfer across generations. To enforce this policy objective, Internal Revenue Code (IRC) Section 401(a)(9) prescribes the statutory framework governing Required Minimum Distributions (RMDs). RMD rules dictate the exact timetable and mathematical formulas under which taxpayers must systematically liquidate and pay ordinary income tax on their tax-deferred retirement accumulations.

Over recent years, Congress has enacted sweeping legislative overhauls—most notably the Setting Every Community Up for Retirement Enhancement (SECURE) Act of 2019 and the SECURE 2.0 Act of 2022. These statutes fundamentally restructured statutory beginning ages, reformed excise tax penalties, eliminated pre-death designated Roth RMDs, and abolished the multi-generational "stretch IRA" for non-eligible designated beneficiaries. Retirement counselors must possess an exact, technical command of these updated rules to safeguard clients from punitive tax penalties and optimize decumulation timing.

Applicable Beginning Ages Under SECURE 2.0

Prior to 2020, the statutory RMD beginning age was fixed at age 70½. The SECURE Act of 2019 increased this threshold to age 72 effective January 1, 2020. SECURE 2.0 further escalated the RMD starting age according to a phased, birth-cohort timetable:

• Age 73: Applies to individuals who attain age 72 after December 31, 2022, and who attain age 73 before January 1, 2033 (specifically individuals born between January 1, 1951, and December 31, 1959).
• Age 75: Applies to individuals who attain age 74 after December 31, 2032 (specifically individuals born on or after January 1, 1960).

   RMD Beginning Age Timetable by Birth Year:
   - Born before July 1, 1949:           Age 70½
   - Born July 1, 1949 - Dec 31, 1950:   Age 72
   - Born Jan 1, 1951 - Dec 31, 1959:    Age 73
   - Born Jan 1, 1960 or later:          Age 75

Statutory Drafting Anomaly Clarification: SECURE 2.0 contained a technical drafting ambiguity regarding individuals born in 1959 (who technically turn age 72 in 2031 under the age-73 rule, but also reach age 74 in 2033 under the statutory language for age 75). IRS guidance and the applicable regulations specify that individuals born in 1959 are governed by the age 73 beginning age.

The Required Beginning Date (RBD) & The "Double RMD" Trap

The statutory deadline by which an account owner must execute their initial RMD is termed the Required Beginning Date (RBD):

$$\text{Required Beginning Date (RBD)} = \text{April 1 of the calendar year } \mathbf{following} \text{ the calendar year in which the owner attains statutory RMD age}$$

For example, if an individual born in 1952 turns age 73 on September 15, 2025, their initial RMD is for calendar year 2025. However, under the statute, they may delay taking this first distribution until their RBD: April 1, 2026.

The Double RMD Trap

While delaying the initial RMD until April 1 of the following year offers short-term cash flow deferral, counselors must warn clients of the dangerous "Double RMD" Trap. All subsequent annual RMDs must be distributed by December 31 of the applicable calendar year. Consequently, if a retiree postpones their first RMD to April 1 of the second year, they are legally required to distribute two full RMDs in that single tax year:

1. The delayed initial RMD (for year 1) taken by April 1.
2. The ongoing second RMD (for year 2) taken by December 31.

Stacking two large ordinary income distributions into a single calendar year frequently spikes the client into higher marginal tax brackets, triggers the 85% Social Security tax torpedo, and trips severe Medicare IRMAA surcharge cliffs two years later. Compare both tax years. Taking the first distribution by December 31 can avoid bunching, while a genuinely lower next-year rate or other facts can favor deferral.

Divisor Calculation Methodology: The Uniform Lifetime Table

Annual RMDs are calculated independently for each calendar year using a precise statutory formula based on account valuation and life expectancy divisors:

$$\text{Annual RMD} = \frac{\text{Account Balance on December 31 of the Prior Calendar Year}}{\text{Life Expectancy Factor (Divisor)}}$$

Valuation Rules

The account balance utilized in the numerator is the fair market value as of December 31 of the immediately preceding year. It is not adjusted for subsequent market gains, market declines, or distributions occurring during the distribution year itself. If a client held $1,000,000 in an IRA on December 31, 2024, and the market drops 25% in early 2025, the 2025 RMD remains strictly pegged to the $1,000,000 prior-year valuation.

Divisor Tables

Under Treasury regulations updated in 2022 (reflecting longer modern life expectancies), the vast majority of account owners utilize the IRS Uniform Lifetime Table (Table III). This table presumes a joint life expectancy between the account owner and a hypothetical beneficiary exactly 10 years younger, ensuring a gradual distribution pace:

Account Aggregation vs. Plan Isolation Rules

Retirement counselors must carefully guide clients regarding which accounts may be aggregated to satisfy RMDs:

• IRAs (Traditional, SEP, SIMPLE): RMDs must be calculated separately for each individual IRA account. However, the resulting total RMD dollar amounts across all IRAs can be aggregated and withdrawn from any single IRA or combination of IRAs owned by that individual.
• 403(b) Tax-Sheltered Annuities: Similar to IRAs, multiple 403(b) plans can calculate their RMDs separately and aggregate the total withdrawal from one or more 403(b) accounts.
• Qualified Employer Plans (401(k), 401(a), 457(b)): Employer qualified plans CANNOT be aggregated across plans or with IRAs. A participant holding three separate 401(k) accounts from prior employers must calculate and withdraw the specific RMD from each respective 401(k) plan individually.
• Spousal Accounts: Spousal IRAs can never be aggregated. A husband cannot satisfy his wife's RMD from his own IRA.

Exceptions: The Still-Working Exception & Younger Spouse Rule

There are two primary statutory exceptions that alter standard RMD timing and divisors:

1. The "Still-Working" Exception

A participant who continues actively working past their statutory RMD age (age 73/75) may defer RMDs from their current employer's qualified retirement plan (e.g., active 401(k) or 403(b)) until April 1 of the year following the year of actual separation from service.

• The 5% Owner Disqualification: The still-working exception is strictly denied to any "5% owner" of the employer. Under IRC Section 416, a 5% owner is any employee who owns more than 5% of the outstanding stock, voting power, or capital/profits interest of the employer entity. 5% owners must begin taking RMDs from their employer plan at age 73/75, regardless of active employment status.
• No Application to IRAs: The still-working exception applies only to the qualified plan of the active employer. It never applies to Traditional IRAs, SEP IRAs, SIMPLE IRAs, or 401(k) plans maintained with former employers.

2. The Joint Life and Last Survivor Table (Younger Spouse Rule)

The standard Uniform Lifetime Table applies to all single owners and married owners whose spouses are not more than 10 years younger. However, if the account owner's sole primary beneficiary is their spouse AND that spouse is more than 10 years younger, the owner is permitted to use the Joint Life and Last Survivor Table (Table II).

• This produces a substantially higher divisor (slower distribution rate), significantly reducing the mandatory annual withdrawal and lowering current-year taxable income.

SECURE 2.0 Penalty Reforms and Form 5329 Waiver Procedures

Historically, failing to take a full RMD triggered one of the most punitive civil tax penalties in the Internal Revenue Code: a 50% excise tax on the undistributed shortfall under IRC Section 4974.

SECURE 2.0 enacted substantial, compassionate penalty relief effective for tax years beginning in 2023:

• Reduction to 25%: The base excise tax for a missed RMD was cut in half, from 50% to 25% of the shortfall amount.
• Further Reduction to 10% (Correction Window): The excise tax is further reduced to 10% if the taxpayer corrects the shortfall within a statutory Correction Window. The taxpayer must withdraw the delinquent RMD amount and submit a tax return reflecting the tax within two calendar years (specifically by the earliest of: notice of deficiency mailing date, tax assessment date, or the last day of the second taxable year beginning after the year the excise tax was imposed).

Requesting a 100% Penalty Waiver (Form 5329)

Under IRC Section 4974(d), the IRS retains statutory authority to waive the excise tax entirely (0% penalty) if the taxpayer establishes that the shortfall was due to reasonable cause and that reasonable steps are being taken to remedy the shortfall.

• To request a waiver, the client must immediately distribute the full delinquent RMD amount from the account.
• The client files IRS Form 5329 (Additional Taxes on Qualified Plans) for the affected tax year, writing "RC" (Reasonable Cause) and the waived amount on the appropriate line.
• The client attaches a detailed written explanation detailing the circumstances of the error (e.g., serious illness, incorrect custodian advice, bereavement) and providing documentation that the full distribution has since been completed. The IRS decides the waiver request; prompt correction and an explanation support the request but do not guarantee approval.

SECURE 2.0 Elimination of Employer Roth RMDs (2024)

Under prior law, an illogical statutory disparity existed between Roth IRAs and designated Roth employer accounts (Roth 401(k), Roth 403(b), Roth governmental 457(b)). While Roth IRAs were completely exempt from lifetime RMDs, designated Roth employer accounts were subject to standard pre-death RMD rules once the participant reached RMD age. To avoid forced distributions of tax-free money, advisors were routinely forced to orchestrate rollover distributions from Roth 401(k) plans into Roth IRAs prior to the participant's RBD.

Section 325 of SECURE 2.0 repealed pre-death RMDs for designated Roth employer accounts, effective for taxable years beginning after December 31, 2023. Today, designated Roth 401(k) and 403(b) accounts enjoy complete lifetime statutory parity with Roth IRAs: no pre-death RMDs are required under any circumstances.

Post-Death RMD Rules Under the SECURE Act: The Death of the Stretch IRA

For decades, wealthy individuals utilized the "stretch IRA" strategy, naming young children or grandchildren as beneficiaries so that inherited IRA distributions could be stretched over the beneficiary's single life expectancy across 40 to 60+ years, generating immense multi-generational tax-sheltered compounding.

The SECURE Act of 2019 dismantled the stretch IRA for deaths occurring after December 31, 2019, replacing it with a mandatory 10-Year Rule for most non-spouse beneficiaries.

The Mandatory 10-Year Rule

Under IRC Section 401(a)(9)(H), for beneficiaries to whom the 10-year rule applies, all inherited account assets must be completely distributed by December 31 of the tenth calendar year following the year of the account owner's death.

The "At-Least-As-Rapidly" Requirement (Final Treasury Regulations, July 2024)

For several years following the SECURE Act, practitioners debated whether beneficiaries under the 10-year rule were required to take annual distributions during years 1 through 9. In July 2024, the Treasury Department issued Final Regulations resolving this issue based on whether the deceased account owner had reached their Required Beginning Date (RBD):

1. Death BEFORE the Owner's RBD: The beneficiary is NOT required to take annual RMDs in years 1 through 9. The beneficiary may withdraw funds at any cadence (or take nothing at all) during the 10-year window, provided that 100% of the account is fully emptied by December 31 of Year 10.
2. Death ON OR AFTER the Owner's RBD: Under the statutory "at-least-as-rapidly" rule, the beneficiary MUST calculate and withdraw annual RMDs in years 1 through 9 (using the beneficiary's single life expectancy divisor), AND must fully liquidate all remaining balances by December 31 of Year 10.

Eligible Designated Beneficiaries (EDBs): Exceptions to the 10-Year Rule

Congress carved out five specific categories of Eligible Designated Beneficiaries (EDBs) who remain exempt from the mandatory 10-year liquidation rule and are permitted to stretch distributions over their single life expectancy:

1. Surviving Spouse: May stretch over single life expectancy, roll over into their own IRA, or elect to be treated as the deceased employee under Section 327 of SECURE 2.0 (delaying RMDs until the deceased spouse would have reached RMD age).
2. Minor Child of the Decedent: May take distributions based on their single life expectancy only until reaching the age of majority (defined as age 21). Upon reaching age 21, the 10-year clock begins, requiring complete distribution by age 31. (Note: Grandchildren do not qualify for this exception).
3. Disabled Individual: An individual who meets the rigorous federal definition of permanent disability under IRC Section 72(m)(7) (unable to engage in substantial gainful activity).
4. Chronically Ill Individual: An individual meeting the special inherited-account chronic-illness definition, including the required certification of indefinite, reasonably lengthy duration rather than merely the ordinary 90-day LTC duration.
5. Beneficiary Not More Than 10 Years Younger: An individual (such as a sibling or partner) who is older than the decedent, or who is younger than the decedent by not more than 10 calendar years.

Non-Designated Beneficiaries (Estates, Charities, Non-Qualifying Trusts)

If the account owner names an entity that is not an identifiable human individual (such as their estate, a charity, or a non-see-through trust):

• If death occurs before RBD, the account must be fully liquidated under the 5-Year Rule.
• If death occurs on or after RBD, distributions must continue over the deceased owner's remaining single life expectancy (the "ghost life expectancy" rule).
