Welcome to the world of the schedule C.
Typically, getting a “stipend” means you are viewed as an independent contractor, not an employee. If you have been paid with checks for the full amount the stipend (no taxes or FICA withheld), then you will probably get a 1099 in January or very early February that shows the amount you were paid.
It is earned income, but it is NOT “wages” or W2 income, and is reported as “business income” on your tax return.
You should be able to use a schedule C-EZ – https://www.irs.gov/pub/irs-pdf/f1040sce.pdf
The good news is that if you had any out-of-pocket expenses associated with your work, you will be able to deduct them as business expenses. For example, if the job requires you to run errands or make deliveries and you do that using your own car, you could deduct the mileage (but you have to have kept track of that!) – or ifyou bought supplies of some sort specifically for that job without getting reimbursed, you could deduct the cost of that. But you probably don’t have much of that.
But the bad news is that if the employer called it a “stipend” and did not deduct payroll taxes, you will have to figure and pay them on your own. These are called self-employment taxes and amount to 15.3% of the total net income – so if you were paid $4000 as a stipend – that would be $612 in self-employment tax owed.
However, you also get to deduct half of that from your total income to reduce your AGI. But that probably won’t help much in your case.
Here are the forms you would be using:
Schedule C EZ - https://www.irs.gov/pub/irs-pdf/f1040sce.pdf
Schedule SE - https://www.irs.gov/pub/irs-pdf/f1040sse.pdf
Form 1040 - https://www.irs.gov/pub/irs-pdf/f1040.pdf (lines 12, 29, 57)
Of course none of us actually fill out these forms on our own - if we are doing our own taxes, we use a software program to do it. There is free software you can use, but some of the free programs won’t handle the schedule C stuff, so it’s something to verify before you start with a free program. One free package that will handle it is CreditKarma – they are new in the tax prep business, only started last year, although CreditKarma itself has been around for many years.
I’d also strongly suggest that you do your own taxes, or at least try to, rather than relying on your parents or their tax guy. Not only because of some of the problems that have already been discussed, but because it is an important life skill. My dad made me fill out my own return back when I was about age 17 and had barely anything to report – and this was back in the day when it was all done on paper – but he wanted me to learn, and I’m glad he did. You can always seek out help later one, but it’s good to at least run through the process on your own.
