I have noticed the same issue. Easy guide calculates a number that is different from what the IRS calculator calculates. In my case there is no local tax there is just state sales tax. I have no idea how it could be possible that the turbotax number doesn't match IRS number, given that to get the IRS number you had to enter just a few numbers (i.e. your dependents, the state, the income band, and the date). How could Turbotax get such simple calculation wrong!
