Forte International Tax, LLC is an international tax services firm focused on global tax analysis and reporting. The firm leverages its international tax expertise through its proprietary software platform, VantagePoint™, to deliver significant tax savings and process improvements. Clients range from Fortune 100 to closely-held companies and their advisors. Founded in 2004, the firm is headquartered in Evanston, IL and has been ranked in Inc. Magazine’s “500 Fastest Growing Private Companies in America.”


Forte’s multi-disciplined international and technology professionals have been developing international tax software for over 30 years, including at the Big 4 accounting firms. The team was instrumental in helping many of the country’s largest and most sophisticated multinational corporations through the Tax Reform Act of 1986 with the International Tax Management system (“ITMS”). ITMS was ultimately acquired by Thomson Reuters, becoming the forerunner of OneSource International. The team migrated to Ernst and Young in the mid-90’s and was responsible for developing FSC/ETI software and leading that firm’s global tax analysis group (“GTAG”).


Utilized internally and licensed by multinational enterprises and global tax advisory firms, VantagePoint is unique in its ability to support sophisticated international tax planning and compliance reporting through a single integrated database. Developed by nationally recognized tax leaders, VantagePoint is aligned with the three major tax processes: Planning, Optimization and Compliance.





Forte was launched in response to the American Jobs Creation Act in 2004 focusing on the first Section 965 Repatriation Holiday, ETI Transition, and DPAD. Forte began developing VantagePoint in 2008 as a fully integrated global tax platform to meet the anticipated needs of international tax reform.
