What Payroll Paperwork Is Actually Required to Formally Pay a Child in the Family Business?
A parent running a small business wants their teenager to help out and get paid for it properly, rather than just handing over cash, and quickly realizes they’re not sure what “doing it properly” actually requires on paper.
The short answer
Hiring a child in a family business generally requires the same payroll setup used for any other employee: a completed Form W-4, a Form I-9 confirming eligibility to work, wages that reflect actual hours worked at a reasonable rate, and accurate wage records kept throughout the year. Some payroll tax rules differ for a child working for a parent’s business depending on how that business is structured, but the paperwork trail itself generally still applies.
The core paperwork most businesses need
- Form W-4. Every employee, including a child, generally completes this form so the employer knows how much federal income tax to withhold from each paycheck.
- Form I-9. This form documents identity and eligibility to work in the United States and is generally required for any employee, regardless of age or family relationship.
- An Employer Identification Number. A business generally needs this number to report wages and payroll taxes, and it’s used on the forms filed for any employee on the books, including a family member.
- State new-hire reporting. Many states require employers to report newly hired employees to a state agency within a set window after they start, and this requirement typically applies the same way to a child as to anyone else hired.
Keeping the wages defensible
The paperwork only means something if the underlying pay is treated seriously. That generally means keeping a written record of actual hours worked, paying an amount that’s reasonable for the type of work being done, and running payments through the same payroll process used for other employees rather than as informal cash. Businesses that skip this step and simply pay a lump sum at year-end, without records of hours or duties, are on much shakier ground if that pay is ever questioned. This kind of documentation discipline matters in the same way keeping organized tax records matters generally — the paper trail is what supports the arrangement if it’s ever reviewed.
Payroll tax differences that sometimes apply
Depending on how the family business is legally structured, some payroll taxes that normally apply to wages, such as Social Security, Medicare, and federal unemployment tax, may work differently when the employee is a minor child of the business owner. These carve-outs are specific and vary based on the child’s age and the business’s legal structure, such as a sole proprietorship versus a corporation, so they’re not automatic simply because the employee happens to be a family member. Because of that variation, this is an area where checking current guidance or working with a tax professional matters more than relying on general assumptions.
Getting the wages to the child
Once wages are properly documented, they still have to actually reach the child in a form that makes sense for their age. Some families route earned wages into a prepaid card built for a minor or a basic checking account, while others set aside a portion in a savings or investment account opened in the child’s name. If wages end up in an account meant for a minor’s own savings, it’s worth understanding that earnings inside that kind of account can carry their own tax treatment, separate from the wages themselves once those wages start generating interest or investment returns.
Where families sometimes trip up
- Treating pay as an allowance instead of wages. Money handed over without hours tracked or a payroll process behind it generally doesn’t qualify as documented employee wages.
- Skipping the standard hiring forms. Assuming a family relationship removes the need for a W-4 or I-9 is a common misconception that doesn’t hold up.
- Paying an amount unrelated to the work performed. Wages disconnected from actual duties or market rates for similar work can raise questions about whether the arrangement is genuine employment.
- Not tracking hours at all. Without records, it becomes difficult to show the wages paid line up with time actually worked.
Putting it in perspective
Formally employing a child in a family business is generally a matter of running the same payroll process used for any other hire — proper forms, an EIN, wage records, and pay that reflects real work. The family relationship doesn’t remove the paperwork requirements; it mainly changes some of the payroll tax mechanics depending on the business’s structure, which is worth confirming against current rules before assuming any exemption applies.
