Best way to enter my W4 that maximizes my net income while minimizing my tax return

Hi,

I file jointly (gross income is approx $215,000) and we both claim 0 dependents on our W4s but yet we owed $3000 in taxes.  What is the best way to fill out our W4 that maximizes our net income while reducing our amount of taxes owed?  For this year, I started withholding an extra amount to account for a possible $3000 amount owed this year ($115 held every paycheck - 26 paychecks in a year).  Any advise is appreciated.
