At GTN, we recognize the importance all clients place on the privacy and confidentiality of their information. While new technologies allow us to more efficiently serve you, we are committed to maintaining rigorous privacy standards. When we store and retrieve your Tax Notebook data, our provider’s (CCH) processing site uses SSL (Secure Socket Layer) technology to ensure all information remains safe and private. SSL is an established and mature internet security standard with two dominant features: data encryption and identification of the secured web server.

Data encryption is the process of transforming legible information into a complex arrangement of illegible information. The only way to make this data legible and useful again is to decrypt it, or reverse the process of encryption. In addition, SSL uses a private/public key combination to identify and encrypt data when it is sent, and to decrypt it when it is received.

Finally, our provider’s internet-based systems are protected behind firewalls, and all mission critical servers are deployed in a cluster environment with high fault tolerant for fail-over.

Completing your Tax Notebook is easy! You simply answer all questions and complete relevant sections of the Tax Notebook online. When your Tax Notebook is complete, you can print a copy for your records, and then submit your tax information to us with just the click of a button!

Please note that our standard fees are based on the completion of the Tax Notebook. You can also engage us to help walk you through the process if needed.
