Whatever she put on her W-4 at work only affects the amount the employer withholds. It does not dictate how her tax return (if any) has to be filed. Her earnings will not affect your tax return at all. As I said before, unless she earns over $6350 in 2017 she will not be required to file a return. Her only reason to file would be to get a refund of any federal tax withheld. Not sure what state you are in; as SweetieJean said, your state tax might be different. But this is late in the year--it is unlikely a teenager will owe taxes for this year. You say she just started working recently. It's always an adventure for parents the first time their teenager has that first job and you have to deal with their income tax.
