May I file returns for multiple workplace locations through Keystone’s e-file Business Portal?

Yes. You may report and file payroll withholding for multiple workplace jurisdictions in one session using Keystone’s Business Portal.

If you have at least one workplace location in a jurisdiction where Keystone is the Tax Officer, you may qualify as a “combined monthly filer”. You must report and file payroll tax every month online, and pay the tax electronically using Keystone’s Business Portal.
