The 2023 picture for Pennsylvania residents
In 2023, Pennsylvania residents paid federal ordinary income tax at brackets topping out at 37%, plus Pennsylvania state tax up to 3.07%, plus Medicare (1.45% + 0.9% additional above $200k single MAGI), plus a federal supplemental-withholding layer on RSU-style income.
2023 AMT exemption
The 2023 federal AMT exemption was $85,700 for single filers. The exemption phased out at 25 cents per dollar of AMTI above $609,350, fully eliminating the exemption for higher earners. That is why ISO exercises in Pennsylvania during 2023 produced AMT bills that surprised people running first-order mental math.
Pennsylvania layer in 2023
Pennsylvania did not impose a separate state AMT in 2023, so federal AMT was the only layer. State ordinary tax still applied to any disqualifying disposition income recognized in the same year.
