Pennsylvania state income tax calculator

Estimate Pennsylvania income tax using the 3.07% flat rate.

How this calculator works

Step 1 starts with the Pennsylvania taxable income you already calculated on your return. If you are a part-year resident or nonresident, the tool applies the Pennsylvania income percentage you provide to focus on Pennsylvania-source income.

Step 2 applies Pennsylvania's flat 3.07% rate to estimate total tax.

Step 3 summarizes the effective and marginal rates so you can see how additional income would be taxed and whether your current estimate matches your expectations.
