Look, as a practical matter, I believe this issue is largely overblown. The standard deduction for single filers for tax year 2023 is $13,850. That means -- even you are a dependent who is claimed on your parents' return -- you aren't going to owe income tax on any "earnings" up to that amount. And beyond that amount, you are going to be taxed at no more than 12 percent, more likely 10 percent, unless you earned more than $41k.
For example, let's say you are an RTOC scholarship winner who attends a school that provides you with free room and board at a value of $15,000 per year. You can wipe out the majority of that amount with the standard deduction. Then, that leaves you with a very small tax bill. In this example, your taxable income would be $1,150, and you'd owe $11.50 in tax on that.
Even if you have a part-time job and earn say an addition $8,000 on the year, and end up with "taxable income" of $9,150, you're likely looking at a tax liability under $100.
As always, consult your tax advisor for actual advice. I am not a CPA, not do I play one on TV, nor did I stay at the Holiday Inn Express last night. That said, I'll gladly take free room and board for pennies on the dollar in taxes.
