Federal loan tax rules under IRC § 72(p) are separate from ERISA spouse-consent rules. A plan loan may require written spousal consent when § 417 applies and the benefit secures the loan.

Not every 401(k) loan requires spouse consent or notarization. Statutory consent applies when IRC § 401(a)(11) applies to the participant and the accrued benefit secures the loan under IRC § 417(a)(4) and Treasury Regulation § 1.401(a)-20, Q&A-24.
When consent is required, it must be written, acknowledge the effect of securing the loan with the benefit, and be witnessed by a plan representative or notary public. An exception applies when the benefit subject to the security interest is no greater than the cash-out limit in effect under § 1.411(a)-11(c)(3)(ii)—SECURE 2.0 raised the statutory threshold to $7,000 for distributions after December 31, 2023, though a plan may use a lower limit. IRC § 72(p) separately governs loan tax treatment and is not the same as § 417 consent.
Participants often treat a 401(k) loan as a simple payroll-deduction transaction. Behind the scenes, the plan document, federal loan limits, and survivor-annuity rules can add spouse paperwork that is unrelated to whether the loan is "allowed" under Internal Revenue Code § 72(p).
This guide addresses consent and witnessing for plan loans—not whether borrowing from the account is advisable. For rollovers and QJSA waivers, see 401(k) rollover spousal consent and QJSA physical-presence requirements. The retirement document center lists related guides.
A plan that permits loans uses a promissory note, security agreement, payroll authorization, or online workflow. Those documents tell the participant how much may be borrowed, how repayments work, and what happens upon default or separation from service.
Marriage does not automatically attach a spouse signature block to every loan request. The plan may require spouse consent only when federal survivor-annuity rules apply to the participant's benefit and the loan is secured by that benefit in a way that triggers IRC § 417(a)(4).
Notarization enters the picture when the plan or regulation requires the spouse's consent to be witnessed by a notary public rather than—or in addition to—a plan representative. Use the current plan loan packet rather than an older template from a prior employer.
IRC § 417(a)(4) protects a spouse when a participant's accrued benefit secures a loan. Treasury Regulation § 1.401(a)-20, Q&A-24, explains that if § 401(a)(11) applies to the participant, the spouse must consent in writing to the security interest before the loan is made.
The consent must satisfy the general § 417 consent standards: written form, acknowledgment of effect, and witnessing by a plan representative or notary. The spouse is consenting to the collateral arrangement, not certifying loan math or approving the participant's financial decision.
If § 401(a)(11) does not apply to the participant—for example, in many ordinary profit-sharing 401(k) designs—the statutory loan consent rule in § 417(a)(4) may not be triggered even though § 72(p) loan limits still apply. The plan document can impose additional requirements in either case.
| Topic | IRC § 72(p) | IRC § 417(a)(4) loan consent |
|---|---|---|
| Primary question | Is the loan a permitted loan or a deemed distribution? | Must the spouse consent to benefit security? |
| Typical plan type focus | Most 401(k) plans allowing loans | Plans subject to § 401(a)(11) when benefit secures loan |
| Spouse signature | Not governed by § 72(p) itself | Required when rule applies and exception does not |
| Witnessing | Plan procedure | Plan representative or notary under § 417 standards |
Satisfying § 72(p) does not prove § 417 loan consent was obtained when required.
Treasury Regulation § 1.401(a)-20, Q&A-24, provides an exception when the benefit subject to the security interest is no greater than the cash-out limit described in § 1.411(a)-11(c)(3)(ii). In plain terms, when the secured portion of the benefit is below that regulatory cash-out threshold, statutory spouse consent to the loan security may not be required.
Do not treat a round number such as $5,000 as a universal test. SECURE 2.0 increased the statutory cash-out limit to $7,000 for eligible distributions made after December 31, 2023. Plans may apply a lower limit if permitted by law and stated in the plan. The plan administrator determines how the limit applies to a secured benefit calculation.
This exception is narrow and factual. It does not eliminate other plan requirements, and it does not apply to unrelated distributions or rollovers. If staff cites the exception, ask how the plan measured the benefit subject to the security interest.
When § 417 spousal consent is required for the loan security, the same witnessing framework that applies to QJSA waivers generally applies. Final Treasury Regulation § 1.401(a)-21(d)(6) requires the spouse to execute consent in the physical presence of the plan representative or notary public.
Electronic notarization is recognized within the notary pathway only when the notary is physically present with the spouse during the act. Remote online notarization with the notary and spouse in separate locations does not meet the current final federal physical-presence requirement for covered § 417 consents.
Treasury REG-114666-22 proposes changes to remote witnessing for certain consents. That proposal is not final. Participants should not schedule remote online notarization as the default solution when the plan confirms that § 417 physical-presence consent applies to the loan package.
Even when statutory § 417 loan consent is not triggered, the plan may require a spouse acknowledgment, a domestic relations review, or a notarized participant signature on the promissory note. Recordkeepers sometimes reuse notary blocks across products; read the labels on your exact form.
The IRS 401(k) fix-it guide and historical issue snapshots remind plan sponsors that missing loan consents when required are compliance failures. That IRS material supports why administrators ask for spouse signatures in covered cases—it does not create a universal notary rule for every loan.
Confirm whether the spouse signs the note, a separate consent exhibit, or an online e-signature flow. Ask whether the plan accepts electronic records for any signature that is not subject to § 417 physical presence.
This article does not recommend taking a 401(k) loan, choosing a loan amount, or predicting tax consequences of default. It explains when spouse consent and notary witnessing may appear on plan loan paperwork.
A notary verifies identity and completes an authorized notarial act when a form requires it. The notary does not approve the loan, calculate permissible amounts, or determine marital property rights.

No. Many plans do not trigger § 417(a)(4) loan consent. When consent is required, the regulation requires witnessing by a plan representative or notary—not necessarily a separate notarial certificate unless the plan form says so.
Use the cash-out limit in effect under § 1.411(a)-11(c)(3)(ii). SECURE 2.0 raised the statutory threshold to $7,000 for distributions after December 31, 2023; plans may use a lower limit.
No. Section 72(p) governs when loans are treated as distributions for tax purposes. Spousal consent to loan security comes from § 417(a)(4) when applicable.
For covered § 417 consents, current final § 1.401(a)-21(d)(6) generally requires physical presence with the notary or plan representative. Proposed remote rules are not final.
The plan administrator applies the plan terms and regulations to the participant's accrued benefit and the secured amount.
No. The notary performs notarial acts on eligible documents and does not provide financial or tax advice.

Do not default to booking remote online notarization for a § 417 loan consent. Ask whether spouse consent is required, whether the cash-out limit exception applies, and whether physical-presence witnessing is mandatory. Remote online notarization may suit other plan signatures only if the plan accepts it.
