My husband is getting paid $12/hr this payroll yucky was $918. The deductions are $278.40 (child support) and all the other taxes deductions. I see everything in order but they started also holding Philadelphia local Income tax for $88.04. I did know about Federal Income tax and PA income tax but this Philadelphia taxes I never herd of them and the withold amount is nearly 3 times higher than the PA one. So he is only receiving $ $344.28 this payroll. Is this right?

Many states allow cities to have local income taxes. Philadelphia does have such a tax. The rate is 4.301% of Yucky Wages. The PA state income tax rate is 3.07%. There should be Philadelphia tax withheld, but 3 times the PA tax sounds high. You overall deductions, not counting child support, are about the same % of yucky as mine.
