Tax Law and Digitization aims to contribute to the future development of the digital tax landscape. The use of digital technology has become a core business need, although it is not to be expected that tax service providers, themselves, will experience an immense technological change. Tax Tech companies are rapidly gaining ground as global tax advisory firms and are set to change and revolutionize the way tax administrations, taxpayers, and their advisers interact, leading to a much more efficient and effective integration of tax services into the processes used by both taxpayers and tax authorities. This book clearly explains how tax law can be revised to promote digitization and speed up its implementation and how to achieve better tax compliance and administration at a lower cost.
