The next question is: is it subject to SE tax, as well as income tax? How was the income reported to you (1098-T, 1099-Misc, 1099-NEC etc)? If 1099-Misc, what box #? What did yo do for or with this money?
Basically, if you were paid for your work, it is also subject toSelf employment (SE) tax. But, it also depends on who benefits. If this is you own personal research project, it s treated as taxable scholarship ("other income". If it has commercial applications, it's self employment income.
If you report it as self employment (Schedule C), then all your expenses are deductible.
