Client Portal

Some business tax clients have already been introduced to our upgraded version of the Client Portal Experience (Portal). This is a newer alternative to securely sharing tax files and documents year-round. While some clients had access to the Portal before, this new version is simpler, more streamlined, and better connected to other PBMares document sharing software.

To request a Portal account, or for user support, email clientportal@pbmares.com.

Check out our Portal FAQs to help you get started.
