Get your taxes done using TurboTax

NEVER claim exempt since the penalties for getting it wrong are painful ... instead adjust your allowances ... if you want less withholding increase the number on the W-4 line 5. If you are a dependent and will make less than $12K for the year enter a 2 on line 5 otherwise you will enter either a zero or one depending on what your annual income will be including this job.
