Disclaimer
Last updated: 6 October 2026
WorldTax.ai is an AI research assistant. It is designed to help you understand tax questions, not to decide them for you.
Not individualised advice
Information and outputs from WorldTax.ai, and on this website, are general and for research and educational purposes. They are not tax, legal, accounting or financial advice, and they do not create an advisory relationship.
AI can be wrong
AI systems can produce incomplete, outdated or incorrect outputs. Tax rules change and depend on your facts, your residence and the tax year. Always check important points against the primary sources, such as legislation, tax treaties and official guidance, which the service aims to point you to.
Keep a professional in the loop
Before filing, making a payment or taking any decision with tax consequences, review it with a qualified professional where appropriate. Responsibility for decisions remains with you and your advisers.
Illustrative previews
The interface preview on our website uses predefined, illustrative examples. It does not calculate tax, determine tax residence, check current law or retrieve live sources.
Coverage
The beta currently covers Spain only. Other countries are planned and are not yet available.
