Open Side Income Tax Calculator →Side income in Pennsylvania is subject to federal income tax at your marginal rate, self-employment tax if applicable, and a flat 3.07% Pennsylvania state income tax. Because side income typically stacks on top of your W-2 salary, it is often taxed at your highest marginal rates. Local income taxes in some Pennsylvania jurisdictions add further cost. The combined marginal rate on side income can easily exceed 40% for mid-to-high earners. This calculator breaks down exactly what you keep from each dollar of side income in Pennsylvania.
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.
