How to Verify Your FEIN Verification & SS-4

During your implementation, Homebase will require you to provide a few federal documents in order to ensure your payroll will be setup correctly.

One of those documents will be a federal Form SS-4, which is the form the IRS uses to assign your company a federal employer identification number (FEIN). Homebase will need this document to verify the name and FEIN being used to ensure proper filing.
