IFG

IFG brings official tax sources into ChatGPT for tax advisers, tax lawyers, accountants and in-house tax teams.

Research legislation, administrative guidance, case law, tax treaties, EU law and OECD publications across the jurisdictions available in IFG. Find a source from a citation or topic, browse a code or treaty, and open the relevant provision with its official publisher link.

Check available text versions and applicability information for a specified date. Read treaty provisions and their tax-effect dates, locate passages in long documents, and retrieve published legal changes. Use the cited sources to support research notes, client work and internal tax analysis.

Coverage, historical depth and applicability evidence vary by source and jurisdiction. IFG identifies missing evidence and partial results so professionals can assess the limits of each source.
