Once you have selected the PDF file you will need to add signature blocks onto the PDF preview by clicking the Add Signature Block button and drawing a box onto the signature section of the document preview on the left. Some forms may already have predefined signature blocks drawn. If they do you will not need to add any yourself. Once you are happy with your signature blocks, you can name the document on the bottom right and then click Save to send that file to your client for signing.

When you click Save, it will notify your client through SMS, Email or Both depending on the setting you have selected for that client. They will then need to login to TaxComm to complete the signature process.

Knowledge-based authentication, commonly referred to as KBA, is a method of authentication which seeks to prove the identity of someone accessing a service such as an electronic signature. KBA is an identity authentication method that asks questions based on detailed information an individual knows. Typically, the knowledge based authentication questions address the taxpayer’s personal and financial history. These are usually multiple choice questions such as the name of their mortgage lender, type of car financed, a former address or phone number. The taxpayer is expected to answer the questions correctly. KBA may not be required for every electronic signature if a prior relationship has been established, you are verifying in person, or other verification of a client’s identity has been achieved. The IRS has provided the following link for additional guidance.
