Where you can find the tax account numbers needed
If you are an existing employer who has previously run payroll in California, you likely already have the IDs and online accounts needed for OnPay to process your tax filings.
If you are a new employer in California, you will need to register your business with the California Employment Development Department (EDD). This must be completed for OnPay to be able to file and pay your California taxes.
If you cannot locate any of this information, please call the California EDD at (888)-745-3886 for assistance.
