RSU tax rate in Pennsylvania: state, local, federal, and FICA on vest income

Searches for an RSU tax rate in Pennsylvania usually mean you want one percentage to plan cash for a vest. Pennsylvania applies a flat state income tax rate to compensation including RSU vest wages per PA Department of Revenue guidance for your filing year — simpler at the state layer than progressive states like New York, but still stacked on top of federal tax, FICA, and possible local wage taxes.

Federal progressive income tax and FICA apply separately on vest FMV. FICA runs nationwide on vest wages with Social Security stopping at the annual wage base and Medicare applying to the full amount. Employer supplemental withholding on equity often uses flat federal methods that can under-withhold compared with your true stacked marginal rate on salary plus vest.

Philadelphia is the local tax story most Pennsylvania RSU holders miss. Philadelphia wage tax applies to residents and many nonresidents working in the city — on compensation including RSU vest FMV — as a separate local layer on top of Pennsylvania's flat state rate. Pittsburgh and other municipalities may impose their own local earned income taxes depending on residence and work location. State rate alone understates total obligation for Philly workers.

Moving from Pennsylvania to Florida or Texas mid-year triggers a part-year Pennsylvania return on pre-move connected income. The New Jersey–Pennsylvania reciprocal agreement affects some cross-border commuters but not all equity scenarios. Remote PA residents working for out-of-state employers still typically owe Pennsylvania tax on vest wages as resident income.

The practical planning number is a combined estimate: Pennsylvania flat state rate per current DOR publications plus applicable Philadelphia or other local wage tax, plus federal marginal rate plus remaining FICA on the vest FMV. Use the Pennsylvania RSU tax guide for mechanism detail and the RSU tax calculator with Pennsylvania selected for a stacked-income estimate.
