The payroll service uses your legal address on all payroll tax forms it
prepares for your company.
Your company's legal name and address are the ones to which your Federal
EIN was issued. If your company is a sole proprietorship, the legal name is
usually the name of the owner, rather than the trade name (or "doing
business as" name) of the business. To verify your company's legal
address, refer to any forms or labels you have received from the IRS.
The payroll service uses your mailing address as a primary address for all
payroll service documents.
The payroll service uses your shipping address for overnight shipments; for
example, for legal documents sent via an overnight service such as Federal
Express or UPS.
Your shipping address must be a street address (not a post office box) and
may be the same as your legal or mailing address.
