An S corporation can put a spouse, child, or parent on payroll, and doing so is a common way to shift income into lower tax brackets, unlock health insurance and retirement benefits, and turn family labor into a deductible business expense. What separates a defensible arrangement from an audit target is straightforward: the wages have to be reasonable for the work actually performed, the person has to run through a real payroll system with real documentation, and each family relationship carries its own tax quirks. An S corp paying family members is held to the same standard as any other employer, with a few extra pitfalls the IRS watches closely.
Reasonable Compensation Comes First
Any shareholder or family member performing more than minor services must receive W-2 wages before taking distributions. Those wages carry the combined 15.3% in Social Security and Medicare taxes, split evenly between employer and employee at 7.65% each.1Internal Revenue Service. Topic No. 751, Social Security and Medicare Withholding Rates Some owners try to duck that cost by paying family members little and moving the rest through distributions. The IRS knows the pattern.
Under Internal Revenue Code Section 1366(e), the IRS can reallocate income among family members when someone provides services or capital to an S corporation without receiving reasonable pay.2Office of the Law Revision Counsel. 26 USC 1366 – Pass-Thru of Items to Shareholders – Section: Treatment of Family Group The agency doesn’t need to prove intent. If the compensation looks off, it can recalculate what each family member should have earned and assess taxes accordingly.
Reasonable compensation means what a non-family employee would earn for the same work in the same industry and location. There’s no formula. The IRS weighs the person’s training and experience, hours worked, complexity of duties, and what comparable businesses pay for similar roles. A business built around one person’s expertise should pay that person more than a business whose revenue comes mainly from equipment or inventory.
Documentation the IRS Expects
When family employment gets audited, the first question is whether the paperwork looks like a real job or something assembled after the fact. Formalize the arrangement before the first paycheck goes out.
Every family member on payroll should have:
- A written job description with specific tasks, required skills, and expected hours. “Assists with business operations” won’t hold up.
- An employment agreement stating pay rate, schedule, and terms, the same one you’d give an outside hire.
- Timesheets or work logs kept contemporaneously. This is the single most important piece of evidence in an audit. Without it, you’re asking the IRS to take your word that the work happened.
- Performance reviews and records of completed projects that tie wages to actual business value.
Run family members through a formal payroll system, withhold federal and state income taxes, issue W-2s, and remit employment taxes on schedule. If the records don’t exist or look thrown together, the burden of proof shifts to you.
Paying Your Child Through an S Corp
Hiring your child creates real income-shifting opportunities, but the S corporation form eliminates a payroll tax break that catches owners off guard. In a sole proprietorship, or in a partnership where both partners are the child’s parents, wages paid to a child under 18 are exempt from Social Security and Medicare taxes, and wages to a child under 21 are exempt from federal unemployment tax. An S corporation is a separate legal entity, and that kills the exemption. Wages your S corp pays your child are subject to income tax withholding, FICA, and FUTA regardless of the child’s age.3Internal Revenue Service. Family Employees
Income Shifting Still Works
Even without the FICA break, payroll wages move income from your bracket to your child’s. A dependent child’s standard deduction for 2025 is the greater of $1,350 or their earned income plus $450, capped at the regular single-filer standard deduction.4Internal Revenue Service. Topic No. 551 Standard Deduction – Section: Dependents These thresholds adjust for inflation. Wages up to that standard deduction amount become a deductible business expense for the S corp while producing little or no federal income tax for the child.
Earned income from a real job is explicitly excluded from the Kiddie Tax, which targets a child’s unearned income like dividends and interest. Wages your child earns for legitimate work are taxed at the child’s own rate.
Those wages also open the door to a custodial Roth IRA. A child with earned income can contribute up to the lesser of that income or $7,500 for 2026. Decades of compound growth from a teenager’s Roth is one of the most powerful long-term moves a family business can make.
The Sole Proprietorship Workaround
Some advisors recapture the FICA exemption by having the S corp owner set up a separate sole proprietorship that provides management or consulting services to the S corp. The sole proprietorship then hires the children. Because the sole prop is the employer, wages paid to children under 18 qualify for the FICA exemption.3Internal Revenue Service. Family Employees The arrangement has to be genuine. The sole proprietorship needs a real business purpose, the services need to be documented, and the fees need to be reasonable. A paper-only structure created to dodge payroll taxes won’t survive scrutiny.
Child Labor Rules
Federal law exempts children working for their parents from most age and hour restrictions in non-agricultural work, letting children under 16 work any time and any number of hours. Parents cannot employ their children in manufacturing, mining, or any occupation the Department of Labor has declared hazardous.5U.S. Department of Labor. FLSA – Child Labor Rules Advisor State child labor laws may add restrictions. Practically, assign work that’s age-appropriate and actually useful: filing, data entry, cleaning, social media, inventory help.
Paying Your Spouse
A spouse on payroll opens two of the most valuable tax planning levers available to small business owners: health insurance deductions and retirement plan contributions. The wages still need to be reasonable for the work performed.
Health Insurance Premiums
When an S corporation pays health insurance premiums for a shareholder-employee who owns more than 2% of the company, those premiums must be included as wages in Box 1 of the W-2.6Internal Revenue Service. S Corporation Compensation and Medical Insurance Issues That sounds like a penalty, but it unlocks the self-employed health insurance deduction on Schedule 1 of Form 1040, which reduces adjusted gross income.7Internal Revenue Service. Instructions for Form 7206 The S corp deducts the premiums as a business expense, and the shareholder reduces personal taxable income.
Watch the family attribution rules. If you own more than 2% of the S corp, the IRS treats your spouse as though they do too, even if their direct ownership is zero. Health insurance premiums for a spouse on payroll follow the same W-2 reporting whether or not they hold shares.
Retirement Contributions
A spouse earning W-2 wages can participate in any qualified retirement plan the company offers. A 401(k) lets the spouse defer salary on a pre-tax basis, with the S corp adding matching or profit-sharing contributions on top. For 2026, the employee deferral limit is $23,500 for those under 50, with an additional catch-up contribution for older participants. A SEP IRA is another option, allowing employer contributions of up to 25% of the employee’s compensation, with a 2026 cap of $72,000.
Non-discrimination rules require contribution percentages to be consistent across eligible employees. Whatever formula the S corp uses for the owner has to apply equally to family members and any other eligible staff. Plan design matters when relatives are on payroll.
Paying Your Parent
Paying a parent for legitimate work creates a deductible business expense, but it can wipe out your ability to claim that parent as a dependent. You can only claim a parent as a qualifying relative if their gross income stays below the annual threshold, which for 2025 is $5,050, and you provide more than half of their total support.8Internal Revenue Service. Dependents – Section: Qualifying Relative Wages the S corp pays your parent count toward that gross income, so even a modest salary can push them over the limit.
Whether the tradeoff pays off depends on the numbers. The business deduction reduces the S corp’s taxable income dollar for dollar; the lost dependency affects your personal return. For most owners paying a parent any meaningful amount, the business deduction wins. If your parent is on Social Security and the added wages would trigger taxation of those benefits, the math gets more complicated and worth running with a tax advisor.
Audit Exposure and Penalties
The IRS treats unreasonable compensation in S corporations as a high-priority audit area. The pattern that draws attention is simple: an owner who clearly drives the revenue takes a small salary and large distributions. When the ratio looks engineered to minimize payroll taxes rather than reflect what the person actually did, expect questions.
If wages get reclassified, the assessment includes unpaid employer and employee FICA plus interest running back to the original due dates. The IRS may add accuracy-related penalties of 20% on any underpayment attributable to negligence or disregard of the rules.9Office of the Law Revision Counsel. 26 USC 6662 – Imposition of Accuracy-Related Penalty on Underpayments
The personal exposure goes further. Under the Trust Fund Recovery Penalty, any person responsible for collecting and paying over employment taxes who willfully fails to do so can be held personally liable for the full amount of the unpaid employee-side taxes.10Internal Revenue Service. Trust Fund Recovery Penalty (TFRP) Overview and Authority In a family-run S corp, that responsible person is almost always the owner. The corporate form provides no shield. If the business can’t pay, the IRS comes directly to you for the withheld income tax and the employee share of FICA.
Documentation assembled in real time is what defuses these inquiries. Salary surveys or comparable job postings supporting reasonable pay, contemporaneous timesheets showing actual hours, and a clear business rationale for each family member’s role will resolve most audits before they become disputes. Owners who treat family payroll as an afterthought tend to find out the cost when the IRS totals the bill.
