Blue J's content library expands to include IBFD cross-border tax content

Today, Blue J is officially launching IBFD content within the platform, expanding our content library to include authoritative international tax guidance from the global leader in cross-border taxation. With Blue J’s expanded content library, practitioners can now generate clearer, more defensible answers to complex international tax questions.

IBFD is the home of international taxation, serving tax practitioners, enterprises, governments, and academic institutions worldwide. With nearly 100 years of publishing expertise, IBFD is best known for its deep treaty analysis, country commentary, and international tax guidance spanning 220+ jurisdictions. 

Better answers for complex cross-border tax questions

When dealing with topics like permanent establishment (PE) risk, offshore compliance, and multinational planning, tax teams have to navigate an increasingly complex international tax landscape. Shaped by factors such as the introduction of OECD pillar two model rules, this landscape demands in-depth tax research.

By integrating IBFD’s curated tax content, Blue J can now deliver that in-depth international research. Tax teams can look forward to accurate, defensible responses to a wider range of questions spanning transfer pricing, digital economy rules, and more.

International tax research, simplified with AI

Blue J simplifies international tax research by allowing practitioners to ask complex cross-border questions in plain language, the same way they would consult a trusted colleague. Informed by IBFD’s international tax expertise, Blue J responds in seconds with comprehensive answers backed by trusted sources, reducing time spent searching through databases and allowing more time for advising clients.

“Our clients operate in a world where international tax complexity is accelerating, and they need not just answers, but clarity and confidence in real time,” said Benjamin Alarie, CEO and co-founder of Blue J. “Integrating IBFD’s global content directly into Blue J’s platform puts authoritative international tax answers at professionals’ fingertips, transforming what once took hours of research into seconds. This is the first of several major content partnerships that will redefine speed, confidence, and reliability in cross-border tax research.”

Jan Maarten Slagter, CEO of IBFD, added “Integrating IBFD’s international tax content into Blue J’s AI platform marks a significant step in maximizing the accessibility of tax knowledge, aligning with our mission of knowledge sharing around the world.
