Federal Tax Form (W-4)
If a parent is claiming you as a dependent, you can only claim Single with 0 withholding allowance on Line 5. You cannot claim Exempt.
If a parent is not claiming you as a dependent, you can claim 0 or 1 withholding allowance. More tax is withheld when you claim a withholding allowance of 0 versus 1.
You cannot claim exempt if (1) you will be earning more than $750 from January through December 2004 and more than $250 of unearned income (e.g., interest and dividends), and (2) another person can claim you as a dependent on his/her tax return.

Both tax forms must be signed and dated.
