IFG

Tax research grounded in official sources and citations

Listed in ChatGPT

Overview

What IFG does

IFG, from fiscal.ia, is built for tax research rather than tax filing. It locates official material on a question and pulls the text: statute, administrative guidance, treaties, and decided cases.

The second half of the workflow is verification. Substantive claims in a draft answer are checked back against the source text, and IFG holds back a final draft when inline citations are missing or unverified. That refusal is part of the design rather than a failure state.

What results is a research assistant with an enforced citation requirement, aimed at work where the underlying authority has to be shown.

Who it is for

Tax advisers and in-house specialists who have to point to the law behind an answer.

What stands out

The citation check is a gate, not a suggestion: drafts without verified inline sources do not get released.

Where IFG is listed

IFG is listed in the ChatGPT apps directory only. fiscal.ia has no connector under the same domain in the Claude directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them.

ChatGPT apps are built on MCP, and the same server can back a Claude connector, so the absence is a distribution decision rather than a technical one.

This is an independent catalogue entry compiled by Node8 from IFG's public marketplace listing as it stood in August 2026. Listing facts come from the marketplaces; the comparisons against the rest of the directory and any live-endpoint measurements are Node8's. Node8 is not affiliated with fiscal.ia, and inclusion here is not an endorsement.
