My dependent daughter has a w-2 can I enter it on my tax return under her name.

[AmyW]

No. You should not claim your child's W-2 or self-employment income on your return even if you claim him as a dependent. The dependent would file his/her own tax return and should check the box Someone else can claim me on their tax return in the personal information section. 

The IRS requires a tax return to be filed for your daughter if she has:

• unearned income was over $1,050
• earned income was over $6,300, or
• earned and unearned income together total more than the larger of (1) $1,050, or (2) total earned income (up to $6,300) plus $350.
