2.1 Traditional IRA Contribution Limits, Compensation Requirements, and Spousal IRAs

Statutory Framework and Eligibility Principles

Individual Retirement Accounts and Annuities (IRAs) are governed by Section 408 of the Internal Revenue Code (IRC). Established by the Employee Retirement Income Security Act of 1974 (ERISA), the Traditional IRA serves as an individual tax-deferred vehicle designed to encourage long-term retirement savings. However, while anyone may establish an IRA account shell with an authorized custodian or trustee, the legal authority to deposit funds as an annual regular contribution is strictly governed by IRC Section 219.

Under IRC Section 219(a), an individual is allowed an annual deduction for amounts contributed in cash to an individual retirement plan. To make a regular contribution to a Traditional IRA, two foundational statutory requirements must be satisfied:

1. Taxable Compensation Requirement: The contributing individual (or their spouse, in the case of a spousal IRA) must receive taxable compensation during the specific tax year for which the contribution is made.
2. Timely Cash Contribution: The contribution must be made in cash (currency, check, ACH, or wire) and must be deposited by the individual's federal income tax return due date, determined without regard to extensions (typically April 15 of the following calendar year).

Contributions of property (such as stock certificates, mutual fund shares, real estate deeds, or digital assets) are strictly prohibited for regular annual contributions under IRC Section 408(a)(1). Any property deposited as an annual contribution will be rejected by bank operations or treated as an invalid transaction.

The SECURE Act Repeal of the Age 70 1/2 Cap

For more than four decades following ERISA's enactment, federal law imposed a strict age ceiling on Traditional IRA contributions. Under former IRC Section 219(d)(1), no contribution could be made to a Traditional IRA by or on behalf of an individual who attained age 70 1/2 before the close of the taxable year.

The Setting Every Community Up for Retirement Enhancement (SECURE) Act of 2019 (Public Law 116-94) enacted a sweeping statutory reform. Effective for taxable years beginning after December 31, 2019, Section 107 of the SECURE Act completely repealed former IRC Section 219(d)(1). As a result of this legislation, there is no maximum age limit for making regular contributions to a Traditional IRA.

An individual who is 72, 78, or 85 years of age can continue making annual contributions to a Traditional IRA indefinitely, provided they satisfy the earned compensation requirement. This statutory change harmonized Traditional IRAs with Roth IRAs, which have never been subject to an age cap.

Anti-Abuse Offset for Qualified Charitable Distributions (QCDs)

Bank IRA administrators and trust officers must note the statutory interaction between post-70 1/2 Traditional IRA contributions and Qualified Charitable Distributions (QCDs) under IRC Section 408(d)(8)(A). To prevent taxpayers from claiming a double tax benefit (taking a tax deduction for an IRA contribution and subsequently distributing the same pre-tax funds tax-free to charity), Congress enacted an anti-abuse offset rule. Under this rule, the maximum annual $100,000 (indexed to $105,000 in 2024, $108,000 in 2025, and $111,000 in 2026) QCD exclusion is reduced dollar-for-dollar by the aggregate amount of post-age 70 1/2 deductible Traditional IRA contributions that have not previously offset a QCD.

Defining Taxable Compensation (IRC § 219(f)(1))

The legal definition of "compensation" for IRA contribution purposes is set forth in IRC Section 219(f)(1) and Treasury Regulation § 1.219-1(c)(1). For IRA eligibility, compensation is strictly limited to earned income derived from personal services actually rendered by the taxpayer. It does not encompass gross receipts from investments or passive wealth generation.

Statutorily Eligible Compensation

Eligible taxable compensation includes:

• Wages, Salaries, and Tips: Gross remuneration paid by an employer for personal services rendered, as reported in Box 1 of IRS Form W-2 (less non-taxable employee benefits).
• Commissions, Bonuses, and Professional Fees: Variable earned payments received by sales professionals, attorneys, accountants, consultants, and independent contractors.
• Net Earnings from Self-Employment: Sole proprietors (reporting on Schedule C) and general partners (reporting on Schedule K-1) generate eligible compensation under IRC Section 1402(a). However, the net profit from self-employment must be reduced by two mandatory statutory deductions:
  1. The deduction for one-half of the self-employment tax under IRC Section 164(f).
  2. The deduction for contributions made to qualified retirement plans (such as Keogh, SEP, or SIMPLE plans) on behalf of the self-employed individual under IRC Section 404.
• Taxable Alimony and Separate Maintenance: Payments received under a decree of divorce or separate maintenance constitute eligible compensation only if the decree was executed on or before December 31, 2018. Under the Tax Cuts and Jobs Act (TCJA) of 2017, alimony paid under decrees executed or substantially modified after December 31, 2018 is neither deductible by the payor nor includible in the payee's gross income, and therefore cannot support an IRA contribution.
• Nontaxable Combat Pay: Under IRC Section 112, compensation received for active service in a combat zone is excluded from federal income tax. However, the Heroes Earned Retirement Opportunities (HERO) Act of 2006 amended IRC Section 219(f)(1) to explicitly treat nontaxable combat pay as eligible compensation for IRA contribution purposes.
• Difficulty of Care Payments: Foster care payments excluded from income under IRC Section 131 were expanded by the SECURE Act to count as compensation for determining contribution limits (although they cannot generate a tax deduction).

Statutorily Ineligible Income

Income derived from passive holdings, capital investments, or deferred benefits cannot be used to fund an IRA. Ineligible income includes:

• Investment and Portfolio Income: Interest, dividends, capital gains, annuities, and royalty income not derived from personal creative efforts.
• Rental Real Estate Income: Net profits reported on Schedule E from residential or commercial real estate rentals, unless the taxpayer qualifies as a real estate professional whose activities constitute a trade or business subject to self-employment tax.
• Pensions, Annuities, and Retirement Distributions: Monthly pension benefits, retirement annuity distributions, and distributions from qualified retirement plans (401(k), 403(b), governmental 457(b)) or IRAs.
• Deferred Compensation: Payments received from a nonqualified deferred compensation plan (IRC Section 409A) or phantom stock plan representing services performed in prior years.
• Limited Partnership Net Income: Partnership distributions received by limited partners who do not perform personal services for the partnership (IRC Section 1402(a)(13)).
• Government Transfer Payments: Social Security retirement or disability benefits, unemployment compensation, workers' compensation, and child support.

Eligible vs. Ineligible Compensation Summary

Annual Contribution Limits and Catch-Up Provisions

Under IRC Section 219(b)(1), an individual's regular annual contribution to a Traditional IRA is limited to the lesser of:

1. The statutory dollar limit for the applicable tax year; or
2. 100% of the individual's eligible taxable compensation.

Statutory Dollar Caps

Congress periodically adjusts the statutory contribution limit for inflation in $500 increments under IRC Section 219(b)(5)(C):

• Tax Year 2024: $7,000
• Tax Year 2025: $7,000
• Tax Year 2026: $7,500 (IRS Notice 2025-67)

If an individual earns $4,500 in eligible W-2 compensation during 2025, their maximum allowable contribution is capped at $4,500. They cannot contribute the full $7,000 statutory maximum.

Age 50+ Catch-Up Contributions (IRC § 219(b)(5)(B))

Under the Economic Growth and Tax Relief Reconciliation Act of 2001 (EGTRRA), Congress introduced catch-up contributions to assist older workers in accelerating their retirement savings. Under IRC Section 219(b)(5)(B), an individual who attains age 50 or older by December 31 of the taxable year is entitled to an additional catch-up contribution. Section 108 of SECURE 2.0 indexed this amount in $100 increments for years after 2023; it stayed at $1,000 for 2024 and 2025 and rose to $1,100 for 2026.

• 2024 Total Limit (Age 50+): $8,000 ($7,000 base + $1,000 catch-up)
• 2025 Total Limit (Age 50+): $8,000 ($7,000 base + $1,000 catch-up)
• 2026 Total Limit (Age 50+): $8,600 ($7,500 base + $1,100 catch-up)

The catch-up determination is based strictly on the calendar year in which the taxpayer reaches age 50. If an individual's 50th birthday is on December 28, 2025, they are legally considered age 50 for the entire 2025 tax year and may make the full $8,000 contribution on January 2, 2025.

Aggregation Rule Across Traditional and Roth IRAs

Under IRC Section 408A(c)(2), annual contribution limits apply in the aggregate across all Traditional IRAs and Roth IRAs maintained by an individual. A taxpayer cannot contribute $7,000 to a Traditional IRA and another $7,000 to a Roth IRA in the same tax year. The sum of all annual regular contributions made to all Traditional and Roth IRAs owned by a single individual cannot exceed the single statutory limit (for 2026, $7,500, or $8,600 if age 50 or older).

Contributions made to employer-sponsored retirement plans—such as 401(k), 403(b), SEP IRA, or SIMPLE IRA plans—do not count against the individual's regular IRA contribution ceiling.

Contribution Deadlines and Bank Processing Protocols

Under IRC Section 219(f)(3), a contribution is deemed to have been made on the last day of the preceding taxable year if it is deposited on account of such taxable year not later than the time prescribed by law for filing the federal income tax return for such taxable year, not including extensions.

The Standard April 15 Deadline

For calendar-year individual taxpayers, the statutory deadline for making an annual IRA contribution is April 15 of the calendar year immediately following the tax year for which the contribution is designated.

If April 15 falls on a Saturday, Sunday, or a legal holiday recognized by the IRS (such as Emancipation Day in Washington, D.C., or Patriots' Day in Maine and Massachusetts), the deadline automatically advances to the next business day under IRC Section 7503.

Extensions of Time to File (Form 4868) Do NOT Extend the Contribution Deadline

A critical distinction on the CISP examination involves individual income tax filing extensions. While filing IRS Form 4868 grants an automatic 6-month extension of time to file Form 1040 (moving the return due date from April 15 to October 15), Form 4868 does not extend the deadline to make a regular Traditional or Roth IRA contribution.

A taxpayer who files Form 4868 must still deposit their prior-year IRA contribution by April 15. Any deposit made after April 15 cannot be designated for the prior tax year, even if the taxpayer's Form 1040 has not yet been filed.

Bank Operational Custodial Requirements

Financial institutions acting as IRA custodians or trustees are subject to strict administrative reporting standards regarding contribution timing:

1. Written Contribution Designation: When an IRA owner deposits funds between January 1 and April 15, the bank must obtain a written designation on the deposit document specifying whether the funds are intended as a prior-year contribution or a current-year contribution. In the absence of a written designation, the bank's standard custodial agreement typically defaults the transaction to the current calendar year in which the check or wire is received.
2. Postmarked Mail: Industry guidance treats a mailed contribution as timely if the envelope is postmarked on or before the deadline, even if it arrives after April 15; institutions that accept it keep the postmarked envelope and confirm the tax year with the owner. Since December 24, 2025, a USPS final rule clarifies that the postmark reflects when the item reaches the first USPS processing facility, which can be later than the drop-off date, so owners should mail early, get a manual retail postmark or Certificate of Mailing, or contribute electronically.
3. IRS Form 5498 Reporting: Custodians report annual IRA contributions on IRS Form 5498 (IRA Contribution Information). Box 1 reports regular Traditional IRA contributions. Form 5498 is filed with the IRS and mailed to the account owner by May 31 following the contribution year, reflecting contributions made through the April 15 deadline.

Kay Bailey Hutchison Spousal IRAs (IRC § 219(c))

Under general tax principles, an individual who does not work outside the home and receives $0 of compensation would be entirely disqualified from funding an IRA. To eliminate this inequity for stay-at-home spouses, Congress enacted IRC Section 219(c), formally titled the Kay Bailey Hutchison Spousal IRA.

Statutory Requirements for Spousal Contributions

A spousal IRA allows a working spouse with sufficient taxable compensation to fund an IRA for a non-working or lower-earning spouse. To utilize IRC Section 219(c), the following conditions must be met:

1. Legal Marital Status: The couple must be legally married under federal law as of the close of the taxable year (December 31).
2. Joint Tax Return: The couple must file a joint federal income tax return (Married Filing Jointly - MFJ) for the taxable year. Taxpayers who file using the Married Filing Separately (MFS) status are completely disqualified from utilizing the spousal compensation rules of IRC Section 219(c).
3. The Joint Compensation Test: The combined eligible taxable compensation of both spouses must equal or exceed their combined IRA contributions.

Mathematical Mechanics of the Joint Compensation Formula

Under IRC Section 219(c)(1), the maximum annual contribution permitted for the lower-earning spouse is the lesser of:

• The statutory limit under IRC Section 219(b)(1) ($7,500 for 2026, or $8,600 if age 50+); or
• The sum of:
  • The lower-earning spouse's own eligible taxable compensation; plus
  • The higher-earning spouse's eligible taxable compensation, reduced by any regular IRA contribution made by or on behalf of the higher-earning spouse.

Example: For tax year 2025, Jonathan (age 46) earns $130,000 in W-2 wages. His wife, Rebecca (age 44), works inside the home and earns $0. Jonathan contributes the maximum $7,000 to his Traditional IRA. Because they file a joint return (MFJ) and their joint compensation ($130,000) easily exceeds their combined maximum contributions ($14,000), Rebecca can contribute $7,000 to her own Traditional IRA using Jonathan's compensation.

Legal Account Ownership and Titling Prohibitions

A critical compliance rule tested heavily on the CISP exam is the prohibition of joint IRA ownership. IRC Section 408(a) explicitly mandates that an Individual Retirement Account must be maintained for the exclusive benefit of an individual or their beneficiaries.

There is no such legal vehicle as a "joint IRA." A Spousal IRA is not an account owned jointly by the spouses, nor is it an account in the working spouse's name with spousal rights. A Spousal IRA is a standard, distinct IRA titled exclusively in the name and Social Security Number (SSN) of the non-working spouse. The working spouse has no ownership interest, no custodial withdrawal rights, and no administrative control over the account, unless the owner executes a third-party durable power of attorney.

Realistic Bank Operational Case Study: The Post-April 15 Custodial Audit

At First National Bank & Trust, the IRA operations division conducts an administrative compliance audit of all deposit transactions submitted between April 10 and April 18, 2026. The auditor reviews three specific customer accounts to determine regulatory compliance:

Scenario A: The Self-Employed Owner with Plan Deductions

• Client: Gregory (age 52), sole proprietor filing Schedule C.
• Transaction: Deposited $8,000 on April 14, 2026, marked as a "2025 Traditional IRA contribution."
• Income Data: Gregory's draft tax return reveals Schedule C net profit of $9,000. Self-employment tax is about $1,272 ($9,000 × 0.9235 × 15.3%), so he claims an above-the-line deduction of $636 for one-half of it, and he deducts a $1,000 SEP contribution for himself (well under the effective 20% self-employed maximum of about $1,673).
• Analysis: Gregory's net eligible compensation under IRC Section 219(f)(1) is $9,000 - $636 (SE tax deduction) - $1,000 (SEP contribution) = $7,364. Because an individual's contribution cannot exceed 100% of compensation, Gregory's 2025 allowable contribution is capped at $7,364, even though his age-50+ dollar limit is $8,000. The deposit of $8,000 creates an excess contribution of $636 ($8,000 - $7,364), which must be corrected to avoid excise taxes.

Scenario B: The Married Filing Separately Spousal IRA Attempt

• Client: Claire (age 36), homemaker with $0 earned income.
• Transaction: On April 12, 2026, Claire deposited $7,000 into a newly established Traditional IRA, claiming spousal IRA status. Her husband earned $210,000 in W-2 wages.
• Filing Status: Due to pending litigation involving the husband's business, the couple filed their 2025 federal tax return as Married Filing Separately (MFS).
• Analysis: Under IRC Section 219(c), spousal IRA eligibility is strictly conditioned upon filing a joint return (MFJ). Because Claire and her husband filed MFS, Claire cannot access her husband's compensation. With $0 personal earned income, Claire's entire $7,000 deposit represents an invalid excess contribution.

Scenario C: The Tax Return Extension Confusion

• Client: Frank (age 73), part-time employee earning $22,000 in W-2 wages.
• Transaction: Frank visited the bank branch on May 12, 2026, presenting an approved Form 4868 tax filing extension to October 15, 2026, and attempted to deposit $8,000 designated for the 2025 tax year.
• Analysis: The bank teller must reject the prior-year designation. Under IRC Section 219(f)(3), Form 4868 extends the tax return filing deadline, but does not extend the statutory April 15 IRA contribution deadline. While Frank's age (73) is no longer a disqualifying factor due to the SECURE Act repeal of former IRC Section 219(d)(1), the deposit can only be processed and coded on Form 5498 as a 2026 current-year contribution.
