    • Here are a few tips for certain questions that may affect your payroll with Gusto:
    • “First quarter your wages exceeded $100.” You may choose the prior quarter or current quarter. Gusto will only begin filing your taxes once you run a payroll with California wages. If you choose a prior quarter, you will be responsible for filing returns with the agency on your own in the interim.
    • “Taxpayer Representative Contact Information." Do not add Gusto as a Taxpayer Representative.  
    • "Are you an authorized Payroll Agent?" Please select No.
    • "Does this business use professional assistance for payroll reporting?" Please select Yes.
    • "Agency where you want your tax mailings sent?" Please enter your own company name and mailing address. This ensures that your company receives any important communications from the EDD.
  5. Once complete, your request will be sent to the EDD, and may take up to 3 business days for processing. You can log back into e-Services to check on the status of your registration.
  6. In 2018, the new employer rate for unemployment tax in California is 3.4%.
