This e-book contains articles on the subject of “Self-Service for Tax Compliance”. Tax administrations are in a process of increasing the use of modern information and communication technology to improve taxpayer services, compliance, and internal efficiency. The introduction of self-service channels is one way towards more efficient services. If developed and implemented in the right way self-services would be considered as improvements by most taxpayers and lead to better compliance. Such solutions can make tax administrations more cost-effective with less need for human-to-human interaction. To achieve this, tax administrations need to engage and cooperate with the users, software developers, tax intermediaries and other stakeholders. This kind of cooperation is the focus of this e-book.
