What it reported doing in 2024

Tthe ibfd is a private research foundation located in amsterdam, the netherlands. The ibfd is dedicated to providing thorough, complete, and detailed information on international taxation through the collection and dissemination of source documents, data, tables, commentary and analysis of national tax legislation, tax regulations, tax cases, tax treaties, and tax systems of countries located throughout the world. The information is made available to the public primarily through a web-based research platform.

The primary users of ibfd information are accounting firms, law firms, governments, universities, tax advisors and taxpayers in countries throughout the world.

The research staff of the ibfd is comprised of attorneys, accountants, economists and other professionals with expertise and experience in international taxation. Through its tax services department, the ibfd engages in tax training courses for tax professionals and tax administrations and in tax research and consultancy projects for governmental agencies and departments, including the oecd. Through its academic department, the ibfd provides speakers for international tax conferences and hosts visiting post-doctorate fellowship opportunities for university professors and other academics conducting research in international taxation. The ibfd maintains a tax library which is open to the public, including ll.m. Students from universities in the netherlands and other academic institutions and researchers.

Operating model

Revenue model
Earned-program. 98% of the money available for current operations came from fees and other program revenue.
Distribution model
Direct operator. The filing allocates 100% of reported program-service expenses outside its grant, affiliate-payment, and member-benefit lines. This expense classification does not rule out separately announced grant awards.

The verdict

SUPPORTED - A large share of available resources goes toward mission work and most voting board members are independent. The filing reports few safeguards for money sent abroad and the filing does not identify recipients for some grant dollars.
