Filing income tax

I have a 17 year old who has worked this year and made under $600.00. I am carrying her as a dependent because I am single and head of household. Does she have to file a return or do I file her wages with mine?

Dependent's income

Your daughter does not have to file a return because her earned income was under $4,400. Her income is her own so you do not have to include it in your income. To sum it up, you can ignore this income for tax purposes.
