Question 1.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 or unearned income exceeds certain limits. To find these limits, refer to Dependents under Who Must File, 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, you had federal income tax withheld from your pay or you qualify for a refundable tax credit).
