All companies are assigned a unique identifier called a Federal Employer Identification Number (FEIN) by the federal government. It is a
nine-digit number (e.g., 12-3456789). If you are a Ceridian Tax Service customer, you must provide this number to identify your company when you register on this site. This will allow you to access general tax support information on the Ceridian Web site as well as access your company's specific tax information through a link to
Source Tax Online.
You can find your FEIN on your quarterly Form 941 federal tax return report, which is located in your quarterly Ceridian Tax Statement. You can also find it in the Customer Reports or Tax Codes pages of Source Tax Online.
