13.2 Individual Retirement Arrangements (IRAs) & Rollover Rules

Key Takeaways

  • Traditional IRA contributions under IRC §408 are capped at $7,500 (plus a $1,100 age 50+ catch-up) for 2026; tax deductibility is phased out based on Modified AGI if the individual or their spouse is an active participant in an employer-sponsored retirement plan.
  • Roth IRAs under IRC §408A accept non-deductible contributions subject to MAGI income limits, offering 100% tax-free qualified distributions if the 5-year aging rule is met and the distribution is triggered by age 59.5, death, disability, or first-time home purchase (up to $10,000).
  • The Backdoor Roth IRA strategy is governed by the IRC §408(d)(2) Aggregate Pro-Rata Rule, which sums all Traditional, SEP, and SIMPLE IRA accounts owned by the taxpayer on December 31 to determine the taxable portion of any conversion.
  • Direct rollovers and trustee-to-trustee transfers avoid mandatory withholding and have unlimited annual frequency, whereas 60-day indirect rollovers from qualified plans incur 20% mandatory federal withholding and are subject to the strict 1-rollover-per-12-month limit across all IRAs under IRC §408(d)(3)(B).
  • The SECURE Act replaced the lifetime stretch IRA for most non-spouse beneficiaries with a mandatory 10-year payout rule under IRC §401(a)(9)(H), reserving lifetime distributions strictly for Eligible Designated Beneficiaries (EDBs).

Individual Retirement Arrangements (IRAs) & Rollover Rules

Quick Answer: Traditional IRAs (IRC §408) allow annual contributions of $7,500 ($8,600 if age 50+) for 2026, with tax deductibility phased out for active workplace plan participants based on Modified AGI. Roth IRAs (IRC §408A) provide tax-free qualified distributions after satisfying a 5-year clock and an qualifying trigger (age 59.5, death, disability, or $10,000 first-time homebuyer). High earners utilize Backdoor Roths (subject to the IRC §408(d)(2) aggregate pro-rata rule across all non-Roth IRAs) or Mega-Backdoor Roths via after-tax 401(k) dollars. The SECURE Act eliminated the stretch IRA for non-eligible beneficiaries, replacing it with a strict 10-year post-death liquidation rule.


1. Traditional IRAs (IRC §408): Contributions, Compensation & Deductibility

Codified under IRC §408, a Traditional Individual Retirement Arrangement is a personal, tax-deferred trust or custodial account established by an individual wage earner.

Active Participant Status & Deductibility Phase-Outs (IRC §219(g))

While anyone with eligible compensation can make a Traditional IRA contribution, tax deductibility is conditioned on whether the taxpayer (or spouse) is an "Active Participant" in an employer-sponsored retirement plan (401(k), 403(b), SEP, SIMPLE, defined benefit pension, or governmental plan).

2026 Modified AGI Deductibility Phase-Out Ranges

If active participant status applies, deductibility phases out linearly over specific Modified Adjusted Gross Income (MAGI) bands:

Tax Filing StatusActive Participant Status2026 MAGI Phase-Out RangeTax Deductibility Outcome
Single / Head of HouseholdCovered by workplace plan$81,000 – $91,000Full deduction below $81k; partial deduction $81k–$91k; zero deduction above $91k.
Married Filing Jointly (MFJ)Taxpayer IS covered by workplace plan$129,000 – $149,000Full deduction below $129k; partial deduction $129k–$149k; zero deduction above $149k.
MFJ (Spousal Rule under §219(g)(7))Taxpayer NOT covered, but SPOUSE IS covered$242,000 – $252,000Full deduction below $242k; partial deduction $242k–$252k; zero deduction above $252k.
Married Filing SeparatelyCovered by workplace plan$0 – $10,000Phases out rapidly between $0 and $10,000.

Nondeductible Contributions (IRS Form 8606): Taxpayers phased out of deductible contributions may make nondeductible Traditional IRA contributions up to the statutory limit ($7,500 in 2026). Nondeductible basis must be reported annually on Form 8606 to prevent double taxation upon ultimate distribution.


2. Roth IRAs (IRC §408A): Contributions, Phase-outs & Distributions

Codified under IRC §408A, a Roth IRA accepts only non-deductible (after-tax) contributions. In exchange, investment earnings accumulate tax-deferred, and qualified distributions are 100% exempt from federal income taxation.

Income Eligibility Phase-Out Ranges for Direct Contributions (2026)

Unlike Traditional IRAs, high earners are completely barred from making direct contributions to a Roth IRA if their MAGI exceeds statutory limits:

  • Single / Head of Household: Phase-out range is $153,000 to $168,000 of MAGI.
  • Married Filing Jointly: Phase-out range is $242,000 to $252,000 of MAGI.
  • Married Filing Separately: Phase-out range is $0 to $10,000 of MAGI.

Qualified vs. Non-Qualified Distribution Mechanics

To achieve 100% income-tax-free and penalty-free distribution status, a Roth IRA distribution must satisfy BOTH prongs of the statutory test:

│   3. Death (distribution paid to beneficiary or estate).               │
│   4. First-Time Homebuyer expenses (up to $10,000 lifetime cap under   │
│      IRC §72(t)(2)(F) for purchase of primary residence).              │
└────────────────────────────────────────────────────────────────────────┘

Non-Qualified Distribution Ordering Rules (IRC §408A(d)(4))

When a non-qualified distribution occurs, the Internal Revenue Code enforces a highly favorable, statutory ordering rule (First-In, First-Out) governed by Form 8606:

Order 1: Regular ContributionsOrder 2: Conversions/RolloversOrder 3: Earnings\text{Order 1: Regular Contributions} \longrightarrow \text{Order 2: Conversions/Rollovers} \longrightarrow \text{Order 3: Earnings}

  1. Tier 1 (Regular Annual Contributions): Distributed first. Always 100% tax-free and penalty-free, regardless of age or holding period.
  2. Tier 2 (Conversion and Rollover Allocations): Distributed second on a FIFO basis (oldest conversions first). Taxable conversion basis is distributed before non-taxable conversion basis. Distributed tax-free, but subject to the 10% IRC §72(t) early withdrawal penalty if withdrawn within 5 years of the conversion (each conversion has its own separate 5-year clock), unless an exception applies.
  3. Tier 3 (Earnings): Distributed last. Fully subject to ordinary income tax and the 10% early withdrawal penalty unless the distribution is qualified.

└──────────────────────────┴──────────────────────┴──────────────────────┘

The IRC §408(d)(2) Aggregate Pro-Rata Rule

High-income earners blocked from direct Roth IRA contributions utilize the Backdoor Roth IRA technique: contributing to a nondeductible Traditional IRA and immediately converting that balance to a Roth IRA. However, the conversion is subject to the Aggregate Pro-Rata Rule under IRC §408(d)(2):

  • Aggregation Mandate: The IRS treats ALL Traditional IRAs, SEP-IRAs, and SIMPLE IRAs owned by the taxpayer as a single aggregated IRA account on December 31 of the conversion year.
  • Taxable Conversion Formula: Non-Taxable Percentage=Total Unrecovered Nondeductible Basis Across All IRAsTotal Year-End Balance of All IRAs+Current Year Conversion Amount\text{Non-Taxable Percentage} = \frac{\text{Total Unrecovered Nondeductible Basis Across All IRAs}}{\text{Total Year-End Balance of All IRAs} + \text{Current Year Conversion Amount}} Taxable Conversion Amount=Converted Dollar Amount×(1Non-Taxable Percentage)\text{Taxable Conversion Amount} = \text{Converted Dollar Amount} \times (1 - \text{Non-Taxable Percentage})

Strategic Takeaway: If a taxpayer holds $92,500 in pre-tax SEP/Traditional IRAs and makes a $7,500 nondeductible contribution followed by a $7,500 Roth conversion, the basis percentage is $\frac{$7,500}{$100,000} = 7.5%$. Consequently, 92.5% ($6,937.50) of the conversion is immediately taxable, creating an unexpected tax bill! Qualified employer plan assets (401(k), 403(b)) are excluded from this aggregation, so rolling pre-tax IRAs into an employer 401(k) clears the pro-rata trap.


4. Rollover Mechanisms & Regulations

Moving retirement assets between plans and IRAs is strictly regulated to prevent tax avoidance:

└──────────────────────────┴──────────────────────┴──────────────────────┘

The 20% Mandatory Withholding Trap

Under IRC §3405(c), any "eligible rollover distribution" paid directly to an employee from a qualified 401(k) or 403(b) plan is subject to mandatory 20% federal income tax withholding.

  • Example: If a participant requests a $100,000 distribution check with the intent to roll it over into an IRA, the plan administrator must remit $20,000 to the IRS and distribute $80,000 to the participant.
  • The 60-Day Shortfall: To complete a 100% tax-free rollover, the participant must deposit the full $100,000 into the IRA within 60 days, requiring them to fund the $20,000 difference from personal savings. If only $80,000 is deposited, the $20,000 withheld is treated as a permanent taxable distribution subject to ordinary income tax and the 10% penalty under §72(t).

The One-Rollover-Per-12-Month Rule (IRC §408(d)(3)(B))

Under IRC §408(d)(3)(B) (and Bobrow v. Commissioner), an individual is permitted only ONE 60-day indirect rollover across ALL of their IRAs (Traditional, Roth, SEP, and SIMPLE) in any 12-month period.

  • Violating the rule results in the second rollover being treated as an impermissible distribution (taxable + 10% penalty) and an excess contribution subject to a 6% annual excise tax under IRC §4973.
  • Exemptions: Direct trustee-to-trustee transfers, Roth conversions, and rollovers between qualified employer plans and IRAs are exempt from the 1-in-12-month limit.

5. Post-Death Distribution Rules: SECURE Act & The 10-Year Rule

The SECURE Act of 2019 dismantled the traditional "Stretch IRA" for non-spouse beneficiaries, fundamentally restructuring post-death required minimum distributions (RMDs) under IRC §401(a)(9)(H).

└──────────────────────────┴─────────────────────────────────────────────┘

The Five Eligible Designated Beneficiary (EDB) Categories

Under IRC §401(a)(9)(E)(ii), only five specialized classes of beneficiaries qualify as EDBs and retain the right to stretch distributions across their life expectancies:

  1. Surviving Spouse: May elect lifetime stretch over single life expectancy, delay RMDs until the deceased spouse would have reached RMD age, or execute a tax-free spousal rollover to treat the IRA as their own.
  2. Disabled Individual: Certified permanently and totally disabled under IRC §72(m)(7).
  3. Chronically Ill Individual: Certified under IRC §7702B(c)(2) as unable to perform at least 2 activities of daily living (ADLs) for at least 90 days.
  4. Individual Not More Than 10 Years Younger: Beneficiary who is older than the decedent or not more than 10 years younger (e.g., siblings, friends).
  5. Minor Child of the Decedent: May utilize lifetime stretch ONLY until attaining the age of majority (defined as age 21). Upon reaching age 21, the 10-year clock activates, requiring complete liquidation of the remaining balance by December 31 of the year the child attains age 31.
