I bring in cleaning crew couple times per year to clean my apartment. My teen mentioned that she would do the cleaning if I pay her what I pay the crew. I'm fine with that.
She doesn't have any other job right now. So by doing this she'll earn few hundred $$ this year. I'd like to put this money into a Roth IRA for her.
If I open Roth for her, will she need to file tax turn for 2017 even if it's only $300-400? There won't be any record of her employment other than what we agree to and then me handing her some cash.
A quick search seem to suggest that if she earns more than $400, then she'll have to file tax return and pay self employment taxes. Is that right? Does it make sense to keep this under $400?
