Hiring your spouse as an employee is legal, common, and expressly recognized by the IRS, provided the job is real and the pay matches the work. What changes the math is your business structure: a sole proprietorship escapes federal unemployment tax on a spouse’s wages, but an LLC does not, and an S-corporation brings its own rules around health insurance. Done right, putting your spouse on payroll unlocks a Section 105 health reimbursement plan, retirement contributions built on earned income, and a defensible deduction for wages the business was going to pay anyway.
When the Arrangement Holds Up
The IRS wants to see a real employer-employee relationship: you direct the work, your spouse performs actual duties the business needs, and the pay reflects the going rate for that role.1Internal Revenue Service. Married Couples in Business If a bookkeeper in your area earns $35,000, paying your spouse $90,000 for the same tasks is the discrepancy that gets the deduction thrown out. The concern isn’t the family relationship. It’s inflated wages used to shift income.
Document the position the way you would any hire. A written job description, set hours, time records, and a simple employment agreement covering pay rate and duties are what an auditor asks for first. Without them, a defensible arrangement becomes indefensible.
How Your Business Structure Changes the Tax Bill
The single biggest variable is the legal form of your business. LLC owners routinely assume they get the same treatment as sole proprietors, and they don’t.
Sole Proprietorship
Wages you pay your spouse are subject to federal income tax withholding and FICA, but they are exempt from the Federal Unemployment Tax Act.1Internal Revenue Service. Married Couples in Business Federal law specifically excludes services performed by one spouse for the other from covered employment.2Office of the Law Revision Counsel. 26 U.S. Code 3306 – Definitions
Single-Member LLC
Here is the trap. A single-member LLC is a “disregarded entity” for income tax, but since January 1, 2009, the IRS has treated it as a separate entity for employment taxes.3Internal Revenue Service. Single Member Limited Liability Companies Your spouse’s employer is the LLC, not you. Because the FUTA exemption only applies when someone works directly for their spouse, it does not reach a spouse employed by an LLC. FUTA is owed.
Corporation or Partnership
A C-corporation, S-corporation, or partnership (where your spouse is not a partner) owes the full slate of employment taxes on a spouse’s wages, including the employer share of FICA and FUTA.4Internal Revenue Service. Family Employees S-corporations have a separate rule for owner health insurance covered further down.
What FICA and FUTA Actually Cost
Both sides of the payroll owe FICA. Social Security is 6.2% employer and 6.2% employee; Medicare is 1.45% on each side. The combined burden is 15.3% of wages up to the Social Security wage base.1Internal Revenue Service. Married Couples in Business For 2026, Social Security tax applies to the first $184,500 in wages.5Social Security Administration. What Is the Current Maximum Amount of Taxable Earnings Medicare has no cap. Once wages cross $200,000 in a calendar year, you withhold an additional 0.9% Medicare surtax on the amount above that threshold.6Internal Revenue Service. Questions and Answers for the Additional Medicare Tax
When FUTA applies, the rate is 6.0% on the first $7,000 of wages per employee. Most employers qualify for a 5.4% credit, dropping the effective rate to 0.6%, or a maximum of $42 per employee per year.7Internal Revenue Service. FUTA Credit Reduction The credit depends on timely state unemployment payments, so state delinquency raises the federal cost too.
Paperwork to Get Your Spouse on Payroll
Same hire forms as anyone else. Missing one creates penalties independent of the tax strategy.
- Form I-9 verifies identity and work authorization. Examine acceptable documents such as a passport, or a driver’s license paired with a Social Security card, and keep the form on file.8U.S. Citizenship and Immigration Services. 2.0 Who Must Complete Form I-9
- Form W-4 tells you how much federal income tax to withhold. Household income adjustments matter here.9Internal Revenue Service. Form W-4 (2026)
- New hire reporting to your state’s designated agency within 20 days of the start date. Some states require sooner.10Administration for Children & Families. New Hire Reporting
Draft a written job description and an employment agreement covering pay rate, pay schedule, and duties. Not legally required in most cases, but the first thing requested if the position is questioned.
Ongoing Filings and Records
Form 941, the Employer’s Quarterly Federal Tax Return, is due at the end of the month after each quarter: April 30, July 31, October 31, and January 31.11Internal Revenue Service. Employment Tax Due Dates It reports wages paid and taxes withheld for every employee. By January 31, file Form W-2 reporting your spouse’s annual wages and withholdings; a copy goes to the Social Security Administration and another to your spouse.12Internal Revenue Service. About Form W-2, Wage and Tax Statement
Keep W-4s, time sheets, pay stubs, and deposit records for at least four years after the fourth-quarter return for that year.13Internal Revenue Service. Employment Tax Recordkeeping Family employment gets closer scrutiny than arm’s-length hiring, so keep more, not less.
Health Insurance: The Payoff That Justifies the Whole Setup
For many sole proprietors, this is the reason to put a spouse on payroll. A sole proprietor with no other employees can set up a Section 105 health reimbursement arrangement covering the spouse-employee and the spouse’s dependents. That includes you. The business deducts every reimbursement as an ordinary business expense, and the spouse excludes those amounts from income.
The plan must be written and cannot discriminate in favor of highly compensated employees in eligibility or benefits.14eCFR. 26 CFR 1.105-11 Self-Insured Medical Reimbursement Plan When your spouse is the only employee, that requirement is automatically satisfied because the plan covers 100% of the workforce. Reimbursable expenses go beyond insurance premiums to copays, deductibles, prescriptions, dental, vision, and other qualified medical costs. That reaches further than the standard self-employed health insurance deduction, which covers premiums only.
S-corporation owners follow a different path. If you own more than 2% of the stock, the corporation pays or reimburses your health insurance premiums and reports the amount as wages on your W-2. Those premiums are not subject to FICA or FUTA.15Internal Revenue Service. S Corporation Compensation and Medical Insurance Issues You then take an above-the-line deduction on your personal return for the premium amount. The deduction is unavailable for any month in which you or your spouse was eligible to participate in a subsidized health plan through another employer.16Internal Revenue Service. Instructions for Form 7206 – Self-Employed Health Insurance Deduction
Retirement Contributions Unlocked by W-2 Wages
Paying your spouse creates earned income, and earned income opens retirement contribution room that would not otherwise exist. A Solo 401(k) can cover both spouses when the business has no other employees. For 2026, each spouse can defer up to $24,500 in employee contributions, plus an additional $8,000 at age 50 or older; participants aged 60 through 63 get an $11,250 catch-up instead.17Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026, IRA Limit Increases to $7,500 The business can also make employer contributions up to 25% of the spouse’s compensation, with total annual additions capped at $72,000 per person.18Internal Revenue Service. 2026 Amounts Relating to Retirement Plans and IRAs
Your spouse can also fund an IRA. For 2026, the limit is $7,500 per person, or $8,600 at 50 and older, capped at the spouse’s taxable compensation for the year.19Internal Revenue Service. Retirement Topics – IRA Contribution Limits A W-2 salary makes eligibility straightforward.
When Both of You Really Run the Business: Qualified Joint Venture
If both spouses actively participate, the employer-employee structure is not the only option. Since 2007, married couples can elect Qualified Joint Venture status and skip both the payroll setup and a partnership return.20Internal Revenue Service. Election for Married Couples Unincorporated Businesses To qualify:
- Only the two spouses own the business
- Both spouses materially participate
- The couple files a joint return
- Both spouses elect out of partnership treatment
- The business is not a state-law entity like an LLC or partnership
Each spouse files a separate Schedule C and a separate Schedule SE. The advantage is that both spouses build individual Social Security and Medicare credits based on their share of profits.20Internal Revenue Service. Election for Married Couples Unincorporated Businesses Without this election, couples often report all income under one spouse’s Social Security number, leaving the other with no credit toward future benefits.
The tradeoff is that self-employment tax applies to both spouses’ shares of net profit at 15.3% up to the Social Security wage base, while the W-2 route can produce lower total tax at some salary levels and, more importantly, opens the Section 105 and retirement strategies covered above. Which is better depends on how involved each spouse actually is and how much value the health and retirement plans deliver in your situation.
Workers’ Compensation and State Unemployment
Most states require workers’ compensation coverage once you have employees, and a spouse-employee generally counts. Premiums for administrative work are modest, and skipping coverage where required exposes you to fines and personal liability for any workplace injury. A handful of states exempt certain family employees, so check with your state’s workers’ compensation board first.
State unemployment insurance is separate from federal FUTA. Wage bases range from $7,000 to over $78,000, and rates depend on state, industry, and claims history. Some states follow the federal model and exempt a spouse employed by the other spouse’s sole proprietorship. Others do not. Confirm with your state workforce agency before assuming the exemption applies.
