If your parents are not required to file a tax return and do not plan on filling, you certainly can file a tax return for yourself as Single and claim yourself as a deduction since no one else will be claiming you as a deduction. As a single person, you are not required to file an income tax return unless your 2016 taxable income is above $10,350. If your taxable income is below $10,350, and you had income taxes withheld from your paycheck, you may want to file in order to get those taxes paid returned to you in the form of a refund.
