Why only our B2T Engine achieved full automation?
Because only we can perform book-to-tax adjustments automatically.

Other tax provision/calculation products cannot perform the key step of book-to-tax adjustments automatically, and thus cannot perform the whole tax calculation in a fully automated way. They generally would require users to input the adjustment values, or to set up some adjustment formulas, before the calculation can proceed. By contrast, our B2T Engine contains the relevant rates-and-rules of accounting and tax, which have been digitized to be interpreted by the software to perform the adjustments automatically. User interactions are no longer necessary, except for overriding the Engine’s logic.

The breakthrough design is inspired by the principles of the Gao’s Method of Book-Tax Difference Analysis , which perhaps is the most suitable for the software realization of book-to-tax adjustments. The methodology is the brainchild of Professor Gao Jinping , of China National Tax Institute of STA , who first applied it to China GAAP and tax regulations. It is equally applicable to other countries, including the USA.
