Every answer has a legal spine.
A tax answer is only useful if its authority can be reconstructed. IFG reads across the relevant layers, separates binding text from guidance, and leaves the source hierarchy visible.

One question, sourced across borders.
A cross-border case answered inside your assistant: the source country's law, the tax treaty and the anti-conduit rule, each carrying its own official source.

SG-NL royalties · conduit
Dutch bronbelasting trap
MLI principal purpose test
A Singapore operating company pays IP royalties to a Netherlands holding, itself ultimately owned by a Cayman Islands fund with little substance. Which domestic, treaty, beneficial-ownership and anti-abuse conditions must be verified before determining the withholding-tax treatment?
Read 4 official sources · Singapore, the Netherlands and the OECD layer›
2 · Treaty layer. Open the official Singapore-Netherlands treaty text, confirm the version and applicability status, then test every condition attached to royalty relief (Singapore-Netherlands DTA).
3 · Netherlands domestic layer. A subsequent payment to a low-tax or abusive structure can trigger the Dutch conditional withholding-tax rules. The applicable version and rate must be checked for the payment date (Wet bronbelasting 2021).
4 · Anti-abuse layer. Treaty relief may be denied under the Principal Purpose Test in the OECD Multilateral Convention, art. 7. Its application remains fact-sensitive.
Review path: verify beneficial ownership and substance, the treaty and MLI status on the relevant date, and the current Dutch conditional withholding-tax conditions before reaching a conclusion.
Illustrative source path. Current application must be verified for the matter date.

Frequently asked questions.
Does IFG replace my AI assistant?
No. IFG plugs into the assistant you already use (Claude, ChatGPT, Mistral, Gemini, Perplexity) and brings it the official tax sources. You keep your tool, you gain the sources.
Which sources does IFG use?
Only official ones: statutes in force, tax treaties, administrative guidance, case law, rulings and official publications, with a link to the source behind every statement.
What happens if IFG can't find the source?
It says so instead of inventing one. The unverifiable point is flagged as such, never presented as a conclusion.
Is it only for tax specialists?
IFG is built for professionals who put their name on the advice, but anyone who needs a sourced tax answer can use it.
How much does IFG World cost?
World access is included with Solo at €199/month or €1,990/year for 80 requests per month. Team access is available on request.
Do I need to install new software?
No. The connection is made through MCP directly inside your AI assistant, in a few clicks, with no new software to install.
