Again.....Social Security Disability is not taxable unless half your daughter's SS + her other taxable income from the part-time job exceed $25,000 for the tax year.
She only needs to file a tax return to seek any tax withheld from her paychecks. If her W-2 has any amounts in box 2 or box 17 she can file a tax return to seek a refund. Her return must say she can be claimed as someone else's dependent. She will not be refunded for amounts withheld for Social Security or Medicare (boxes 4 or 6) , but she can get a refund for amounts withheld for federal or state income tax.
