Get your taxes done using TurboTax

Also, make sure that you are taking any pre-tax adjustments to your paycheck into account.  If your gross pay was $165,000, but you were having pre-tax deductions for a 401(k) contribution or medical insurance, or a few other things, that reduces your taxable income and you should use the net taxable income figure in the estimator and not the gross.
