If the W-2 is your only income and it is less than $6,300 and you are going to be claimed as a dependent then you do not have to file at tax return. However, if you had taxes withheld from the wages then you should file a return to get the taxes withheld refunded to you. If you do file a return and you are going to be claimed as a dependent make sure that you indicate on your tax return that you can be claimed as a dependent on someone else's return.
