Can I Pay My Spouse Through My Business? (2026 Guide)

Yes, if the spouse actually works in the business and the compensation is reasonable for the work performed. The harder question is whether you should, because for many owners it costs money rather than saving it.

The answer depends almost entirely on entity type and on what you are trying to accomplish, and the good reasons have nothing to do with income splitting.

Why It Usually Does Not Save Income Tax

On a joint return, income is taxed the same regardless of which spouse earned it. Moving $60,000 from your Schedule C to your spouse's W-2 does not change taxable income.

What it does change is payroll tax. Wages paid to a spouse are subject to social security and Medicare tax, and the business owes the employer share.

For a sole proprietor already above the social security wage base, paying a spouse $60,000 adds social security tax that would not otherwise have been owed on those dollars, because the owner's self-employment income above the base is only subject to Medicare.

That is a straightforward cost of roughly $7,440 in additional social security tax with no offsetting income tax benefit. Owners who do this expecting savings are usually worse off.

The Reasons That Actually Work

Retirement plan capacity is the strongest one. A spouse on payroll can defer into a 401(k) and receive employer contributions, expanding household retirement capacity beyond what the owner alone can contribute.

In a solo 401(k) covering an owner and spouse, each can defer the employee limit and each can receive employer contributions, potentially doubling household contributions to $140,000 or more in 2025 before catch-ups.

Health benefits are the second. In a sole proprietorship, employing a spouse allows a medical expense reimbursement arrangement covering the employee-spouse and their family, which includes the owner. This converts out-of-pocket medical costs into a business deduction that also reduces self-employment income.

Social security credits are the third. A spouse with limited earnings history may benefit from building their own credits, though the spousal benefit already provides 50% of the higher earner's benefit, so this only helps where the spouse's own record would exceed that.

The Sole Proprietorship MERP Structure

This is the strategy that genuinely produces meaningful savings, and it works specifically for sole proprietorships and single-member LLCs.

The owner employs the spouse. The business establishes a medical expense reimbursement arrangement that reimburses the employee-spouse for family medical expenses, including the owner as a family member.

Reimbursements are a deductible business expense, excludable from the spouse's income, and reduce net self-employment income, saving both income tax and self-employment tax.

For a household with $22,000 of annual medical costs, the self-employment tax savings alone approach $3,100, on top of the income tax benefit of converting personal medical costs into a business deduction.

This requires a properly drafted plan document and compliance with applicable group health plan rules, which have become more restrictive. It is not a do-it-yourself arrangement, and arrangements set up without proper documentation face significant excise tax exposure.

It does not work for an S corporation, because a spouse of a more than 2% shareholder is attributed the shareholder's ownership under IRC Sec. 318 and is not treated as a regular employee for this purpose.

Documentation Requirements

Whatever the structure, the spouse must actually perform services and the compensation must be reasonable for those services.

That means a job description, time records or a defensible account of duties, wages paid on a regular schedule through actual payroll, a Form W-2, and treatment consistent with other employees.

Paying a spouse $85,000 for bookkeeping that takes four hours a week is not reasonable compensation and will be adjusted. Paying $28,000 for genuine part-time administrative work is defensible.

Payments must actually be made. An accrual on the books with no cash movement is not compensation.

The S Corporation Case

For an S corporation, adding a spouse to payroll is more often a cost than a benefit.

The owner is already an employee with a salary. Payroll tax applies to that salary. Adding a spouse's salary adds payroll tax on those wages as well, and unlike a sole proprietorship, the MERP structure is unavailable due to attribution.

The remaining benefit is retirement plan capacity, which is real. A spouse earning $70,000 can defer the employee limit and receive employer contributions, expanding household retirement savings.

Whether that justifies the payroll tax cost depends on the numbers. For a household already maximizing the owner's plan contributions, adding a spouse can be worth it. For a household not yet maxing the owner's own capacity, it usually is not.

Worked Example: Sole Proprietor With MERP

A consultant operates as a sole proprietor with $340,000 of net profit. Their spouse handles scheduling, invoicing, and client communication roughly fifteen hours a week.

The spouse is placed on payroll at $34,000 annually, which is defensible for the hours and duties. Payroll tax cost is approximately $5,200 including both shares.

A properly documented medical expense reimbursement arrangement covers the employee-spouse and family, reimbursing $24,000 of annual medical and dental costs. This is a business deduction that reduces net self-employment income.

Self-employment tax savings on the $24,000 reduction are approximately $696, since the owner is above the social security wage base, plus income tax savings of roughly $8,880 at a 37% rate on medical costs that were previously non-deductible given the AGI floor.

The spouse defers $23,500 into a solo 401(k) and receives an employer contribution, expanding household retirement capacity by roughly $32,000.

Net benefit is positive but modest on the medical side and substantial on the retirement side. An owner who ran the same structure through an S corporation would have captured the retirement benefit and none of the medical benefit.

Frequently Asked Questions

Does paying my spouse reduce our taxes?

Usually not by itself. On a joint return, income is taxed the same regardless of which spouse earned it, and wages paid to a spouse add payroll tax. The benefits come from retirement plan capacity and, for sole proprietors, medical expense reimbursement.

What is the best reason to employ a spouse?

Retirement plan capacity. In a solo 401(k) covering both spouses, each can defer the employee limit and receive employer contributions, potentially doubling household contributions. For sole proprietors, a medical expense reimbursement arrangement is the second strong reason.

Can I set up a medical reimbursement plan for my spouse?

For a sole proprietorship or single-member LLC, yes, and it converts family medical costs into a business deduction that also reduces self-employment income. It requires a properly drafted plan document and compliance with group health plan rules, so it is not a self-service arrangement.

Does the medical reimbursement structure work for an S corporation?

No. A spouse of a more than 2% shareholder is attributed the shareholder's ownership under IRC Sec. 318 and is not treated as a regular employee for this purpose. The retirement plan benefit remains available.

What documentation do I need?

A job description, a defensible record of duties and hours, wages paid on a regular schedule through actual payroll, a Form W-2, and compensation that is reasonable for the work performed. Book accruals with no cash movement are not compensation.
