拿回家九万, pretax income should be $180,000 or more. Your tax rate
The actual tax act not publish yet. If your income $180k or above, you are in 25% rage. Not 12%. Because many things will count on, such as SS, medical insurance, medicare tax, state tax/property tax, local tax, and etc.
I have 50% deduction and take home only 50%. Still in 25% range.
