What Kids With Summer Jobs Need to Know About Taxes

Even teens who won’t make enough money to owe federal taxes need to file a withholding form with their employer.

My son is in high school and will start his first summer job in a few weeks. What does he need to do about taxes?

First, he will need to fill out an IRS Form W-4 to specify how much money will be withheld from his paychecks for income taxes. “Most teenagers working their first summer job won’t earn enough money to end up owing any federal income tax at the end of the year,” says Dan Thomas, a CPA and personal financial specialist in Orange County, Calif.

Generally, anyone with earned income of less than $6,300 in 2015 does not need to file a tax return. If he will earn less than that, your son could check the box on Form W-4 that allows him to claim he is exempt from withholding. Note, however, that a child who is claimed as a dependent by someone else cannot claim an exemption from withholding if he has more than $350 of unearned income (from interest and dividends, for example) and his total income is more than $1,050.

Thomas often recommends that teens claim zero or one withholding allowance instead, in case they end up having enough earned income to owe some tax. “That minimizes the sticker shock of having a significant balance due,” he says. If your son has more money withheld than he owes in taxes, he’ll get a refund when he files Form 1040 next spring. For more information, see IRS Publication 929 Tax Rules for Children and Dependents.

No matter how your son fills out the W-4, he’ll still have Social Security and Medicare taxes withheld from his paychecks, and that money won’t be refunded even if he files a return. But it counts toward his Social Security earnings record, which is used to determine his benefits in the future. “If you look at your own Social Security statement, it will include wages all the way back to that first job in high school,” says Kelley Long, a member of the National CPA Financial Literacy Commission. Your son will also have to specify how much to withhold in state taxes.

Kids with summer jobs should also consider contributing to a Roth IRA; you just need earned income from a job to be eligible to contribute to a Roth, regardless of your age. “If parents want to really supercharge the saving and investing aspect of the summer job, they can push their children to establish a Roth IRA,” says Thomas. Your son doesn’t have to use his own money; you can give him the money to contribute. He can contribute up to the amount of money he earned for the year, with a maximum of $5,500.

Starting a Roth when he’s young can give your son a huge head start for the future. He can withdraw the contributions tax-free and penalty-free at any age, and he can withdraw the earnings tax-free after age 59½. “I have done this with my own children for the past few years, and they have become passionate savers and investors,” Thomas says.
