You file your own tax return separately from your parents. You can file before them and with another company. Your return is completely separate from theirs. You just have to check a box on your return saying you can be claimed as a dependent.
If you make 12,000 or less of W2 income you should not owe any tax and should get a refund of all the withholding. If you get a 1099Misc instead of a W2 that is taxed differently. We think you will be getting a W2 for your Wages, ask your employer.
