$65000/year or $2500 every two weeks: if i claim 3 exemptions instead of zero, how much would my take home pay be?

it will usually take a week or two for changes to your withholding to take effect in payroll.  however 0 deductions will withhold more per check than 3.  so if at 0 deductions you are having to pay in april then i would suggest not changing your w2 to 3 deductions.  instead in the section for extra with holding add $25 per week.  this should leave you with a more manageable return in april.
