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.
