This week’s question comes from Debbie, a sole proprietor. I read that children under age 18 are not subject to federal employment taxes. My children are now in college and work part-time year-round. I know they are now subject to FICA taxes. Do FUTA taxes apply to children of sole proprietor who are age 18 or older? Answer: Sole proprietors who hire their own children under age 21 are not required to pay Federal Unemployment Tax Act (FUTA) tax on those children’s wages. Once the children reach age 21, the exemption no longer applies. Contact Vision Payroll if you have any questions on payroll taxes on children.
