How much does an unmarried dependent student have to make before he or she has to file an income tax return?
If you are an unmarried dependent student, you must file a tax return if your earned and/or unearned income exceeds certain limits.
To find these limits refer to Who Must File, Dependents in Publication 501, Exemptions, Standard Deduction and Filing Information.
Even if you do not have to file, you should file a federal income tax return if you can get money back (for example, had income tax withheld from your pay; you qualify for the earned income credit; you qualify for the additional child tax credit). See Who Should File in Publication 501, Exemptions, Standard Deduction and Filing Information, for more examples.
