Pennsylvania charges 3.07% flat + local state income tax plus local taxes in some areas. Use the w-4 withholding calculator pre-loaded with Pennsylvania rates.
Open W-4 Withholding Calculator →Getting your W-4 right in Pennsylvania is important because you need to coordinate federal withholding with Pennsylvania's flat 3.07% state withholding. If your W-4 is set too conservatively, you lend the government an interest-free loan; too aggressively, and you face an underpayment penalty. Workers in Pennsylvania localities with income tax need to account for that additional withholding layer. This calculator helps you dial in the right federal withholding amount given your Pennsylvania state tax situation.
Pennsylvania levies a flat 3.07% state income tax on all taxable income regardless of how much you earn. This makes tax planning straightforward: for every additional dollar you earn, 3.07 cents goes to Pennsylvania. However, certain localities in Pennsylvania impose their own income taxes, which effectively raise the combined state and local rate above 3.07%. Be sure to check whether your city or county adds a local income tax.
