6.3 Account Aggregation Rules and Qualified Charitable Distributions (QCDs)

Statutory IRA Aggregation Rules (Treas. Reg. § 1.408-8)

Many retirement investors maintain multiple individual retirement arrangements across several financial institutions. Treasury Regulation Section 1.408-8(e) sets forth a flexible, two-step statutory framework governing how account owners may satisfy their annual Required Minimum Distributions across multiple accounts:

1. Step 1: Account-by-Account Separate Calculation: The account owner must independently calculate the Required Minimum Distribution for each separate Traditional IRA, SEP IRA, and SIMPLE IRA owned, dividing each account's prior December 31 fair market value by the owner's applicable life expectancy factor.
2. Step 2: Aggregate Total Distribution: Once each individual RMD is determined, the owner is permitted to sum the calculated amounts into a single cumulative total. The owner may then distribute the total aggregate dollar amount from any single IRA or any combination of IRAs owned by that individual.

Commercial and Portfolio Flexibility

The statutory aggregation rule provides critical wealth management flexibility. An investor holding real estate, private stock, or long-term certificates of deposit (CDs) in a self-directed Traditional IRA is not forced to liquidate illiquid assets to satisfy that specific account's RMD. Instead, the owner may calculate the RMD for the illiquid account and withdraw the entire required dollar amount from a liquid, cash-rich Traditional IRA or SEP IRA held at a commercial bank.

Non-Aggregatable Plan Types: CISP Core Testing Distinctions

A central focus of the CISP examination is mastering the strict statutory boundaries separating aggregatable retirement plans from non-aggregatable plans. Mixing non-aggregatable plan types constitutes an operational failure resulting in severe excise tax penalties for under-distribution under IRC Section 4974:

1. Traditional/SEP/SIMPLE IRAs vs. Employer Qualified Plans

Qualified employer retirement plans—including 401(k), 403(a), profit-sharing, money purchase pension, and defined benefit plans—are governed by IRC Section 401(a)(9). An IRA RMD cannot be satisfied by taking a distribution from a qualified employer plan, and an employer plan RMD cannot be satisfied from an IRA.

Furthermore, defined contribution employer plans cannot even be aggregated with one another: an employee with two separate 401(k) plans from prior employers must independently calculate and distribute the RMD from each respective plan.

2. Traditional IRAs vs. Section 403(b) Tax-Sheltered Annuities

Section 403(b) plans maintained for employees of public schools and 501(c)(3) tax-exempt organizations possess their own internal aggregation rule under Treasury Regulation Section 1.403(b)-6(e)(7): a participant may aggregate multiple 403(b) contracts and take the total RMD from a single 403(b). However, 403(b) accounts cannot cross-aggregate with IRAs. An IRA distribution cannot satisfy a 403(b) RMD, and a 403(b) distribution cannot satisfy an IRA RMD.

3. Personal Owner IRAs vs. Inherited (Beneficiary) IRAs

An Inherited IRA (beneficiary IRA) established following the death of an account owner under IRC Section 401(a)(9)(B) operates under a completely distinct tax and distribution regime. An account owner cannot aggregate their personal IRA RMD with an Inherited IRA RMD. Personal RMDs must be distributed from personal IRAs, and inherited RMDs must be distributed from inherited IRAs.

4. Inherited IRAs Across Different Decedents

Under Treasury Regulation Section 1.408-8, an individual who inherits multiple IRAs may aggregate them only if the IRAs were inherited from the exact same deceased individual and are held in the same beneficiary capacity. If a taxpayer holds an inherited IRA from their deceased father and another inherited IRA from their deceased mother, the two accounts cannot be aggregated. Each inherited account must distribute its own calculated RMD independently.

5. Roth IRAs

Because original Roth IRA owners are completely exempt from lifetime RMDs under IRC Section 408A(c)(5), Roth IRAs have zero RMD liability and cannot participate in aggregation.

Qualified Charitable Distributions (QCDs) Under IRC § 408(d)(8)

First enacted on a temporary basis under the Pension Protection Act of 2006, made permanent by the Protecting Americans from Tax Hikes (PATH) Act of 2015, and expanded by SECURE 2.0, the Qualified Charitable Distribution (QCD) represents one of the most powerful tax-planning instruments available to senior IRA owners.

Under IRC Section 408(d)(8), an individual may distribute funds directly from a Traditional or Roth IRA to an eligible charitable organization completely tax-free, with the distribution counting dollar-for-dollar toward the owner's annual RMD.

1. The Exact Age 70½ Eligibility Requirement

To execute a valid QCD, the account owner or beneficiary must have attained exact age 70½ on or before the date of the distribution. A critical CISP exam distinction is that although the SECURE Act and SECURE 2.0 increased the RMD starting age to 72, 73, and eventually 75, Congress deliberately retained exact age 70½ as the statutory threshold for QCDs.

An individual who is 71 or 72 has no lifetime RMD obligation, but is fully eligible to execute tax-free QCDs. However, the age requirement is strictly enforced to the exact calendar date: if an individual's 70½ birthday occurs on August 15, an attempted charitable transfer executed on August 14 fails as a QCD and is treated as a fully taxable distribution.

2. Direct Trustee-to-Charity Payment Mandate

Pursuant to IRC Section 408(d)(8)(B), the distribution must be made directly from the IRA trustee or custodian to the qualifying charitable organization. Permissible delivery methods include:

• Direct wire or electronic ACH transfer from the IRA custodian to the charity;
• Custodial check issued payable directly to the legal name of the charity and mailed by the bank;
• Custodial check issued payable directly to the charity but delivered to the account owner, who then physically hands the check to the charitable organization (permitted under IRS Notice 2007-7).

Impermissible Execution: A check made payable to the account owner and subsequently endorsed over to the charity is statutorily disqualified. It is treated as a 100% taxable distribution to the account owner, followed by a personal charitable donation.

3. Statutorily Excluded Charitable Recipients

To qualify for QCD treatment, the recipient must be a public charity described in IRC Section 170(b)(1)(A). IRC Section 408(d)(8)(B)(i) explicitly excludes three specific entity types:

1. Donor-Advised Funds (DAFs): Sponsoring organizations holding segregated accounts where donors maintain advisory distribution privileges (under IRC § 4966(d)(2));
2. Supporting Organizations: Entities categorized as Type I, Type II, or Type III supporting organizations under IRC Section 509(a)(3);
3. Private Non-Operating Foundations: Private grant-making foundations under IRC Section 509(a).

Directing IRA funds to a DAF or private foundation disqualifies the transaction from QCD status, triggering ordinary income taxation on the entire distributed sum.

4. Annual Statutory Dollar Limits and Inflation Indexing

Prior to 2024, the annual QCD cap was frozen at $100,000 per taxpayer per year. Section 307 of SECURE 2.0 indexed the annual limit for inflation (in $1,000 increments) for years after 2023:

• Tax Year 2023: $100,000
• Tax Year 2024: $105,000
• Tax Year 2025: $108,000
• Tax Year 2026: $111,000 (IRS Notice 2025-67)

The statutory cap applies per individual taxpayer. For a married couple filing jointly where both spouses are age 70½ or older and maintain their own separate IRAs, each spouse may distribute up to the maximum limit from their respective accounts (a combined $222,000 in 2026).

5. SECURE 2.0 Split-Interest Entity Election

Section 307 of SECURE 2.0 introduced a historic expansion permitting a one-time election to distribute a portion of the annual QCD limit to a split-interest entity:

• Eligible Entities: Charitable Remainder Unitrusts (CRUTs), Charitable Remainder Annuity Trusts (CRATs), and Charitable Gift Annuities (CGAs).
• Statutory Limits: $50,000 baseline, indexed for inflation to $53,000 in 2024, $54,000 in 2025, and $55,000 in 2026.
• Statutory Restrictions: The election may be made in only a single taxable year during the owner's lifetime. The trust or annuity must be funded exclusively by QCDs, all non-charitable income interests must be held solely by the IRA owner and/or their spouse (non-assignable), and CGAs must maintain a fixed payout rate of at least 5%.

Tax Advantages and RMD Satisfaction Mechanics

The tax architecture of a QCD offers substantial advantages over a standard taxable distribution coupled with an itemized charitable deduction:

Exclusion from Gross Income vs. Itemized Deductions

A standard distribution followed by a charitable gift requires the taxpayer to include the withdrawal in gross income on Form 1040 Line 4b and claim an itemized deduction on Schedule A. However:

• Most senior taxpayers take the standard deduction and receive little or no tax benefit from itemized charitable deductions (beginning in 2026, non-itemizers may deduct only a limited amount of cash gifts).
• An itemized charitable deduction does not prevent elevated Adjusted Gross Income (AGI).

In contrast, a Qualified Charitable Distribution is 100% excluded from gross income and AGI under IRC Section 408(d)(8)(A). Keeping AGI depressed delivers substantial compounding tax benefits:

• Prevents or reduces Medicare Part B and Part D IRMAA premium surcharges;
• Minimizes the percentage of Social Security benefits subject to taxation (IRC § 86);
• Preserves deductions and credits subject to AGI phaseout thresholds.

Dollar-for-Dollar RMD Satisfaction

Under Treasury regulations, the earliest distributions taken from an IRA in an RMD calendar year are deemed to satisfy the RMD. A QCD executed during an RMD year satisfies the account owner's RMD dollar-for-dollar up to the annual QCD limit. If an owner has a $40,000 RMD and executes a $40,000 QCD, their entire RMD is fully satisfied with $0 of taxable income.

The Post-70½ Deductible Contribution Anti-Abuse Offset

To prevent aggressive tax sheltering (deducting a regular IRA contribution and immediately distributing it tax-free via a QCD), Congress enacted the anti-abuse rule of IRC Section 408(d)(8)(A). The excludable QCD amount is reduced dollar-for-dollar by the aggregate cumulative amount of deductible Traditional IRA contributions made for tax years in which the taxpayer attained age 70½ or older, reduced by any prior-year offsets.

Custodial Reporting, Tax Filing Protocols & Substantiation

Bank administrators must understand the specific operational reporting workflows governing QCDs:

1. Form 1099-R Custodial Reporting

IRA custodians do not certify QCDs as tax-exempt on Form 1099-R. The custodian has no legal responsibility to determine whether the recipient charity meets 501(c)(3) requirements or whether the client obtained proper receipts. Consequently:

• Box 1 (Gross Distribution) reports the full amount paid to the charity.
• Box 2a (Taxable Amount) typically reports the gross amount, or the custodian checks the "Taxable amount not determined" box.
• Distribution code: through 2025 there was no QCD code, so custodians used Code 7 (Normal Distribution). The 2026 instructions add code Y in box 7a to identify a QCD, but using it is optional for 2026; a custodian that does not adopt it continues to report code 7.

2. Taxpayer Form 1040 Reporting Protocol

The legal responsibility to claim QCD tax-free treatment rests entirely with the taxpayer and their tax preparer on Form 1040:

• Line 4a (IRA Distributions): Enter the full gross distribution from Form 1099-R Box 1.
• Line 4b (Taxable Amount): Enter $0 (if the entire distribution was a qualifying QCD) or the remaining taxable balance.
• Adjacent Notation: Write "QCD" directly on or next to Line 4b on the return.

3. Contemporaneous Written Acknowledgment (CWA)

Under IRC Section 170(f)(8), to sustain the tax exclusion, the donor must obtain a formal Contemporaneous Written Acknowledgment from the charity prior to filing Form 1040. The acknowledgment must state the dollar amount received and explicitly affirm that no goods or services were provided in exchange for the contribution.

Realistic Bank Administrative Scenario: Multi-Account RMD and Prohibited Charity Request

At First National Bank & Trust, senior IRA officer Teresa reviews account activity for customer Eleanor, age 74.

Client Circumstances and Holdings

Eleanor maintains the following retirement account balances on December 31, 2024:

1. Traditional IRA #1 (First National Bank): $500,000 FMV (2025 RMD = $19,607.84)
2. Traditional IRA #2 (External Brokerage): $300,000 FMV (2025 RMD = $11,764.71)
3. Inherited Traditional IRA (First National Bank, from deceased brother): $250,000 FMV (2025 RMD = $15,000.00)
4. Section 403(b) Plan (from university employment): $200,000 FMV (2025 RMD = $7,843.14)

Eleanor visits the bank with two specific instructions:

• Instruction A: Aggregate all four RMD amounts (totaling $54,215.69) and distribute the entire sum from Traditional IRA #1.
• Instruction B: From that distribution, issue a $30,000 check directly to her family's Donor-Advised Fund (DAF) at a local community foundation as a Qualified Charitable Distribution.

Administrative Review and Compliance Resolution

1. Enforcing Aggregation Boundaries: Teresa advises Eleanor that under Treasury Regulation Section 1.408-8, she may aggregate her two personal Traditional IRAs ($19,607.84 + $11,764.71 = $31,372.55), and withdraw the entire $31,372.55 from Traditional IRA #1. However:
   • The Inherited IRA cannot aggregate with personal IRAs; its $15,000 RMD must be taken directly from the Inherited IRA account.
   • The 403(b) account cannot cross-aggregate with IRAs under Treasury Regulation Section 1.403(b)-6(e)(7); its $7,843.14 RMD must be taken directly from the 403(b).
2. Rejecting the Donor-Advised Fund QCD: Teresa reviews Instruction B and identifies that Donor-Advised Funds are statutorily barred from receiving QCDs under IRC Section 408(d)(8)(B)(i). She informs Eleanor that issuing a check to the DAF will result in a fully taxable $30,000 distribution.
3. Alternative Charitable Structuring: Eleanor modifies her instruction, directing Teresa to issue a $25,000 check directly to an accredited public hospital foundation and a $5,000 check to an animal shelter (both qualifying 501(c)(3) public charities). Both checks are issued directly from Traditional IRA #1.
4. Operational Execution and Reporting:
   • The $30,000 direct charitable transfers satisfy $30,000 of Eleanor's $31,372.55 personal IRA RMD completely tax-free.
   • Eleanor withdraws the remaining $1,372.55 in cash from Traditional IRA #1 to fulfill her aggregate personal RMD.
   • The bank issues Form 1099-R in January 2026 reflecting a $31,372.55 gross distribution coded with Code 7. Teresa provides Eleanor with a written summary advising her tax preparer to report $31,372.55 on Form 1040 Line 4a, $1,372.55 on Line 4b with notation "QCD", and reminds her to retain the charities' written acknowledgment receipts.
