How can we help?

New company registration in Pennsylvania

Income and Unemployment taxes

  1. Register for both tax accounts online using the PA-100 Enterprise Registration Form
  2. Click the Register online button and follow the prompts.
  3. You should receive your account number automatically after registering.
  4. The new employer rate for unemployment tax is generally 3.689% (except for construction businesses which are assigned 10.2238%). You can enter this rate as you wait to receive an unemployment account number, but make sure to update Gusto with the correct unemployment tax rate once you receive your official rate statement from the agency.
