Based on the information you supplied, your tax liability would be estimated at $4700. You did not say how much withholding you have, so you would subtract the withholding from the $4700. If you had more in withholding than tax, you would get a refund. If you had less than $4700 withheld you would owe when you filed your return.
And how can I ensure that $4700 is withheld in federal taxes?
