Can your spouse join the business retirement plan? Review actual work, compensation, tax status, other employment and employee coverage.

A spouse who helps with scheduling, bookkeeping or client service may already be doing meaningful work in the business. Including that person in the retirement plan can be worth exploring, but the answer begins with the employment and compensation facts rather than a desired contribution amount.

Marriage alone does not create eligible plan compensation. Confirm the work performed, how the business is taxed, the spouse's status and the plan's eligibility terms. A properly supported arrangement can improve family retirement saving; an unsupported payroll entry can create tax and plan problems instead.

Establish the role before calculating the contribution

Describe the spouse's actual duties, expected hours and compensation arrangement. Retain records consistent with the work performed and the business's normal payroll practices. The compensation should be defensible for the services, rather than chosen solely to produce a contribution target.

An LLC designation does not answer the tax question by itself. A business may be treated as a sole proprietorship, partnership or corporation for federal tax purposes, and those classifications change the compensation calculation. An owner who is a partner is not treated the same as an ordinary employee receiving W-2 wages. [1]

For an S corporation, shareholder distributions are not retirement-plan compensation. Wages for services can support contributions under the applicable plan rules, and reasonable compensation requirements need to be considered. Transferring cash to a spouse or allocating a distribution does not automatically convert it into eligible wages. [2][3]

For a self-employed owner or partner, retirement-plan earned income involves adjustments; it is not simply the gross revenue deposited into the business account. Ask the CPA and administrator to use the appropriate calculation for the actual tax status. [1]

Follow a contribution through a real payroll assumption

Suppose Jordan owns an S corporation. Jordan's spouse, Taylor, performs documented bookkeeping and administrative work and receives $40,000 of W-2 wages. Assume that pay is reasonable for the work, Taylor is 45, the plan's eligibility requirements are met and all applicable testing and contribution conditions are satisfied.

Taylor elects $15,000 of employee deferrals for 2026. Suppose the plan also provides an employer contribution equal to 25% of eligible compensation. On $40,000, that employer contribution is $10,000, producing $25,000 in the business plan for Taylor: $15,000 from payroll and $10,000 from the employer.

The $15,000 employee deferral is below the 2026 basic personal limit of $24,500. The combined $25,000 is also below both Taylor's stated compensation and the general 2026 defined contribution dollar ceiling of $72,000. Those comparisons are necessary checks, not proof that every other plan requirement has been met. [1][4]

The employer formula also needs to be applied as the plan requires for other eligible participants. It is not an informal permission to contribute 25% only for the spouse while ignoring the owner's or employees' entitlements. Jordan needs a complete employer contribution projection covering everyone entitled to the formula before choosing the amount the business can afford.

Now change one fact: Taylor has also deferred $12,000 into an unrelated employer's 401(k) during 2026. Adding the proposed $15,000 would produce $27,000 of personal deferrals, exceeding the $24,500 basic limit by $2,500. Under these simplified assumptions, only $12,500 remains for employee deferrals in the family business plan. The separate employer contribution calculation does not reset Taylor's personal deferral limit. [1][4]

Recheck who else must be considered

An arrangement covering only a business owner and an eligible spouse can have a different administrative profile from one covering common-law employees. Hiring staff, changing ownership or operating another business can change the analysis. “Solo” in a product name does not override eligibility or related-employer rules. [1][5]

Give the administrator the complete employee census, including service and ownership information, and disclose related businesses. Do not assume someone can be excluded just because the family intended the account for household retirement savings. Ask specifically how new hiring would change participation, testing, contributions and reporting.

A spousal IRA is a different arrangement. Under applicable joint-return and compensation rules, it can allow an IRA contribution for a spouse without sufficient separate compensation. That does not establish employment in the business or create compensation for a workplace retirement plan. Keeping the two concepts separate avoids planning with the wrong set of rules. [6]

Make the arrangement manageable year after year

Estimate the household benefit alongside payroll taxes, employer contributions, administration costs and cash needs. A larger retirement contribution can be useful, but it also commits cash that the business may need for operations. Plan distribution restrictions mean the account is not a substitute for working capital.

For a plan subject to ERISA, appropriate fiduciary oversight includes prudent provider selection and monitoring. Owner-and-spouse-only arrangements may have different ERISA coverage, so confirm which duties apply rather than treating every family business plan identically. Tax qualification and operational requirements still deserve attention. [7]

Have the CPA, payroll provider and retirement administrator agree on compensation definitions, elections and contribution deadlines. Keep the supporting role description and payroll records with the business records, and check that deposits match the election and plan formula, including any reduction needed to coordinate another job's deferrals.

The practical next step is a documented eligibility and compensation review, followed by a full contribution estimate. That can help a family business save more consistently while reducing the risk that a well-intended benefit becomes an expensive correction later.
