Question for the Money Doctors
Question submitted on May 14, 2019.
QuestionMy 12 year old son will likely earn about $750 mowing lawns in 2019. I would like to start a Roth IRA for him. I understand I can contribute up to $750 for him into a custodial Roth IRA. What I don't understand is the tax implications of such a move. He will have to file a tax return claiming his self-employment income as taxable income. What will he owe on $750 in self-employment income at the Federal and State of Missouri level?
I think it's a great idea to contribute to a Roth IRA. Continuing contributions at such an early age, if left untouched, have a chance to grow to a nice sum later in life.
The tax question is not as simple as it may appear. If he has no other income, he will not have a Federal income tax liability. I cannot adequately address how Missouri handles earned income. As you mentioned, he more than likely will have a Federal self-employment tax liability. However, he will be able to deduct business related expenses, such as fuel, supplies and mileage, against this income. Therefore, the amount taxable for self-employment purposes could be less than $750. I would suggest contacting a local CPA to get their input as they can go into detail about your Missouri question and also better address expense deductions.
