Simplifying Joint Signatures on Form 8879: A Seamless Solution for Couples Sharing an Email Address

Chris Farrell

At tax time, firms frequently encounter joint filers who share a single email address. Traditionally, signing Form 8879 electronically required each taxpayer to have their own email, complicating the signing process for many couples. Liscio has addressed this common challenge, enabling joint signers to easily complete their Knowledge-Based Authentication (KBA) and sign Form 8879 securely, using the same email address and even the same device.

The Problem: Limited Email Addresses, Complicated Signatures

Many couples maintain only one shared email account, creating friction when both individuals must independently authenticate and digitally sign important documents like Form 8879. This not only frustrates clients but also delays document processing, slowing down workflow and efficiency within your firm.

The Liscio Solution: Joint Signatures Simplified

Liscio's innovative solution allows both taxpayers to complete their KBA and digitally sign their Form 8879 seamlessly from the same email address and device. Our streamlined workflow ensures compliance, reduces friction, and significantly enhances the client experience.
