Spouse as Bookkeeper: Family Business Gold IRA Guide

Family business owners who pay a spouse as the household bookkeeper have a narrow but powerful combination of retirement vehicles available. The Solo 401(k) one-participant plan can cover both spouses without becoming an ERISA plan, the Spousal IRA fills the gap if one spouse has no earned income, and IRS-eligible bullion can sit inside any of those accounts. This guide covers the 2026 mechanics that small-business households use to coordinate a Solo 401(k), a Spousal IRA, reasonable compensation for the bookkeeper spouse, and a gold IRA allocation across both balances.

Spousal IRA mechanics for family business households

A Spousal IRA is not a separate IRA product. The term describes the IRC Section 219(c) rule that lets a non-working spouse contribute to a traditional or Roth IRA when the working spouse has enough earned income to cover both contributions and the couple files a joint federal return (IRS Publication 590-A). The account is opened in the non-working spouse’s own name and is owned by that spouse. The working spouse’s earned income is the source of the contribution under the rule.

For 2026, the regular IRA contribution limit is 7,000 dollars per account, with a 1,000 dollar catch-up at age 50 and above. A family business household where the bookkeeper spouse takes no W-2 wage can still fund an IRA in the bookkeeper spouse’s name by using the working spouse’s earned business income. The contribution can be traditional, Roth (subject to the Roth income phase-out for the household), or split.

The Roth phase-out is the key planning point. For 2026, the Roth IRA modified adjusted gross income phase-out for married filing jointly begins at 246,000 dollars and ends at 256,000 dollars (IRS Roth IRA contribution amount tables). Family business households at or below the lower threshold can fund both Roth IRAs at the full amount. Households above the upper threshold cannot fund a Roth IRA directly and may evaluate a back-door pathway, subject to existing traditional IRA balances and the pro-rata rule.

The Spousal IRA framework changes the moment the spouse begins to draw a W-2 wage from the family business. With earned income in the spouse’s own name, the IRA in the bookkeeper spouse’s name becomes a regular IRA funded from the spouse’s own wages, not a Spousal IRA. The contribution limit and the Roth phase-out treatment remain the same, but the source of funds changes the documentation and the audit trail.

Coordinating both spouses inside a Solo 401(k)

The one-participant 401(k) plan, often called a Solo 401(k), is designed for a business owner with no full-time common-law employees other than a spouse (IRS One-Participant 401(k) Plans). The spouse exception is the structural feature that makes the Solo 401(k) attractive to family-business households where the spouse already handles bookkeeping or administrative duties. The spouse becomes a second participant in the same plan trust without converting the plan into an ERISA plan.

Each spouse participant has independent contribution capacity in 2026. The Section 402(g) employee elective deferral cap is 24,500 dollars per participant. The age 50 plus catch-up is 8,000 dollars. The SECURE 2.0 super catch-up for participants who are 60, 61, 62, or 63 in 2026 is 11,250 dollars in place of the regular catch-up. The Section 415(c) overall annual additions cap is 72,000 dollars per participant, excluding catch-up, and the Section 401(a)(17) compensation cap that limits the 25 percent employer profit-sharing rate is 360,000 dollars (IRS COLA Increases for Dollar Limitations on Benefits and Contributions).

Adding the bookkeeper spouse as a participant doubles the family household’s deferral capacity. A two-earner household with one S corporation owner paid 140,000 dollars and a bookkeeper spouse paid 50,000 dollars can defer up to 49,000 dollars in employee deferrals combined for 2026, plus employer profit-sharing of up to 25 percent of each spouse’s W-2 wages. Each spouse’s profit-sharing is calculated on that spouse’s own compensation and is capped at the 72,000 dollar 415(c) per-participant figure.

The plan document is the legal foundation. A custodian-provided prototype or a custom plan document defines whether the plan supports two participants, whether each can elect Roth designated contributions, whether in-service distributions at age 59 and a half are allowed, and whether the plan can hold IRS-eligible alternative assets including bullion. Some prototypes default to a one-participant configuration and require an amendment to add the spouse. Confirming the plan document supports two participants before payroll-funded deferrals begin is the cleanest path.

The Department of Labor treats a plan that covers only the owner and the owner’s spouse as outside Title I of ERISA. Adding any other common-law employee, including a part-time non-spouse helper above the eligibility threshold, generally converts the plan into a covered ERISA plan with Form 5500 filings, fiduciary duties, and an annual nondiscrimination test. The spouse exception is the structural reason the Solo 401(k) can be expanded to two participants while staying outside ERISA.

Gold IRA allocation between the two accounts

A household holding IRS-eligible bullion in retirement accounts can place the metal inside the Solo 401(k) trust, inside a self-directed IRA, or split across both. Each account is its own legal vehicle. The bullion bought with a Solo 401(k) participant’s profit-sharing dollars is allocated to that participant’s balance inside the plan trust. The bullion bought with funds rolled into a self-directed IRA is allocated to that IRA. The household-level gold position is the sum.

IRC Section 408(m)(3) sets the eligible bullion standards that apply to IRAs and to qualified plans holding precious metals (26 U.S. Code Section 408). Gold must be 99.5 percent fine, with a statutory carve-out for American Gold Eagles. Silver must be 99.9 percent. Platinum and palladium must be 99.95 percent. The bullion is held at an IRS-approved depository in the trustee’s name. A gold value calculator helps reconcile the dollar amount of the position with the spot value and premium of the chosen products, and the how to verify physical gold guide describes home tests useful if a participant later takes an in-kind distribution.

Allocation decisions between the spouses’ balances are practical, not tax-driven, because both Solo 401(k) participant balances and most Spousal or own-name traditional IRAs are tax-deferred. Three patterns are common in family business households. The first weights the larger balance to keep the smaller balance liquid for ongoing contributions or distributions. The second weights the Roth side, when either spouse holds a Roth Solo 401(k) subaccount or a Roth IRA, because future appreciation comes out tax-free under the Roth qualified distribution rules. The third weights the spouse with the longer expected horizon to retirement.

Reasonable compensation for the bookkeeper spouse

The wage paid to a spouse who is an employee of the family business must be reasonable for the services performed under IRC Section 162(a)(1), which limits the business’s deductible compensation expense to ordinary and necessary amounts (26 U.S. Code Section 162). The reasonableness standard is the wage a comparable arms-length employer would pay for the same work in the same labor market. The Solo 401(k) employer profit-sharing piece sits on top of the W-2 wage, so paying the spouse below market while assigning full bookkeeper duties effectively understates both the deductible wage and the employer profit-sharing capacity.

For a bookkeeper handling accounts receivable, accounts payable, payroll, sales tax filings, and quarterly federal filings, the U.S. Bureau of Labor Statistics reports a median annual wage for bookkeeping, accounting, and auditing clerks in the range of 47,000 to 50,000 dollars in recent surveys, with regional variation (BLS Bookkeeping, Accounting, and Auditing Clerks wage data). Family businesses sometimes pay below this range when the spouse works part-time, and above this range when the role expands to office manager or controller duties.

The documentation matters as much as the wage. A written job description, time records or a clear duty schedule, a payroll register, year-end Form W-2, quarterly Form 941 filings, and an owner resolution authorizing the role and rate together substantiate the reasonable compensation position if the IRS audits the wage. Without records, the IRS can challenge the wage as either insufficient (recharacterizing employer profit-sharing or distributions) or excessive (disguised contributions). Consult your tax advisor for the specific wage figure that fits your business and labor market.

Two case studies: different business types

The two illustrations below describe hypothetical fact patterns common among family-business households. They are anonymized profiles, not specific recommendations. Tax outcomes depend on filing status, state of residence, other income, plan document terms, and timing. Consult your tax advisor and a licensed advisor before electing.

Case A: S corporation cafe, owner-operator with bookkeeper spouse

Anonymized profile based on a single-shareholder S corporation that owns a neighborhood cafe. Owner W-2 wages from the S corporation: 95,000 dollars. Bookkeeper spouse W-2 wages: 42,000 dollars (handling AR, AP, payroll, sales tax, and quarterly filings, supported by a written job description and a time log). Both spouses are 54. The S corporation sponsors a self-directed Solo 401(k) under a plan document that authorizes precious metals and a Roth designated subaccount.

For 2026, each spouse defers 24,500 dollars employee elective plus the 8,000 dollar catch-up. The S corporation contributes 25 percent of each spouse’s W-2 wages as employer profit-sharing, capped per participant by the 415(c) cap. Total household 2026 contribution: 49,000 dollars of deferrals, 16,000 dollars of catch-up, and roughly 34,250 dollars of profit-sharing combined. The plan acquires 60,000 dollars of American Gold Eagles inside the plan trust, allocated 40,000 dollars to the owner’s balance and 20,000 dollars to the bookkeeper spouse’s balance, reflecting the prior cumulative profit-sharing weight.

The bullion is held at an IRS-approved depository in the trustee’s name. Each spouse’s plan statement shows the allocated metal as part of their participant balance. The Roth subaccount stays in equities to keep tax-free growth working on the more volatile asset class.

Pitfalls to avoid

Three pitfalls show up most often when family business households coordinate Solo 401(k), Spousal IRA, and gold positions. The first is paying the spouse a token wage and treating it as full bookkeeper compensation. The IRS examines wage reasonableness when reviewing employer profit-sharing capacity. A token wage understates the family’s contribution capacity and weakens the audit position.

The second pitfall is adding a non-spouse common-law employee without revisiting the Solo 401(k) status. Hiring a part-time helper who meets the plan’s eligibility threshold converts the Solo 401(k) into a multi-participant plan subject to ERISA, with new Form 5500 filings, fiduciary duties, and nondiscrimination testing. Family business owners who plan to expand the workforce should evaluate the plan structure before the first qualifying employee starts.

The third pitfall is purchasing IRA-prohibited or plan-prohibited metals. Collectible coins outside the IRC Section 408(m)(3) carve-outs are not eligible inside an IRA or a Solo 401(k). Purchasing such a product produces a deemed distribution of the entire amount used to buy the disqualified asset (IRS Publication 590-A). The custodian or trustee, the dealer, and the participant should each verify eligibility before purchase.
