Quick Facts

Any employee who works in Pennsylvania and wants to set or change state tax withholding files this form.
It captures your name, address, Social Security number, filing status, number of allowances, and any additional amount you want withheld.
File a new W‑4SP when you start a Pennsylvania job, when your personal tax situation changes, or whenever you want to adjust withholding.
Give the completed form to your employer’s payroll department. No direct filing with the Pennsylvania Department of Revenue is required.
Incorrect allowances can cause too much tax to be taken out (reducing take‑home pay) or too little (leading to a large balance due at year‑end).
1. Download the latest W‑4SP from the PA Department of Revenue website. 2. Fill in personal info, select filing status, and count your allowances. 3. Add any extra withholding amount if desired. 4. Sign and date the form. 5. Hand it to payroll and keep a copy for your records.
