We analyze the safety, privacy, and precision of using artificial intelligence in the tax field.
Using artificial intelligence to manage taxes raises reasonable doubts: How do I know the AI isn't wrong? Can I trust that my data is protected? What is the difference between using ChatGPT and a specialized tool?
This guide explains why not all AIs are equal in fiscal matters, how a truly reliable AI system like Aitax works, and what you should demand from any tool that processes your tax data.
Tools like ChatGPT, Claude, or Gemini are generalist models: they are trained to answer on any topic, from cooking recipes to programming code. This makes them versatile but dangerous in legal contexts.
Generalist models invent information when they are unsure. In taxation, this can mean:
Models have cutoff dates in their training. If tax regulations changed after that date, the AI doesn't know and will provide obsolete information.
Spanish taxation requires deep and specific knowledge: thousands of binding rulings from the AEAT, Supreme Court jurisprudence, and specific criteria according to asset types and brokers.
Generalist AIs function as "black boxes": they give an answer but do not explain where they got the information or why they chose that criterion.
Aitax does not use generalist models. Instead, it combines specialized AI trained specifically in Spanish taxation with a double validation system called Aitax Guard.
When you upload documents, Aitax automatically detects the need for legal backing and activates access to official sources.
Unlike generalist models, Aitax Guard shows you:
Aitax Guard allows you to see the original source: it highlights the exact paragraph of the law and explains its interpretation. You don't depend blindly on the AI; you have the evidence to verify it.
✅ Generalist AI: Fast but imprecise, no legal guarantees, impossible to verify.
✅ Aitax Guard: Specialized, transparent, verifiable with official regulations.
