IFG

For tax advisers, tax lawyers, accountants and in-house tax teams. IFG gives ChatGPT the official tax text in force on the date of the facts: the exact wording, its applicability status, its earlier and later versions, and a link to the official publisher. ChatGPT reasons and answers; IFG supplies and cites the sources. The official text opens inside ChatGPT.

Coverage: the 27 EU member states (French overseas territories included), Switzerland (federal and cantonal), the United Kingdom, Monaco, Andorra and the United States (federal law and selected states); EU law; the tax treaty networks of these countries and the multilateral convention (MLI); OECD publications and the UN Model.

Sources: statutes and codes, regulations, administrative guidance (such as the French BOFiP), rulings, case law, parliamentary history, official rates and parameters.

Links: each provision is connected to the acts that amend it, the guidance and case law that interpret it, and, for EU directives, the national provisions that transpose them.

Find a text from its citation or title, browse a code or treaty, open the provision you need, and see what changed since a given date.

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