Bernardo Mesquita analyses the risks and opportunities of artificial intelligence in the work of tax authorities
Bernardo Mesquita, principal associate in the tax team at Morais Leitão, is the author of the article “The challenges of implementing AI-based solutions in tax authorities’ decision-making processes”, where he examines the growing impact of artificial intelligence (AI) on tax authority decision-making.

The opacity of algorithms, the potential for data bias and the lack of clear reasoning in automated decisions are among the key challenges identified.
Bernardo Mesquita advocates for essential safeguards, including the prohibition of fully automated tax rulings, mandatory human oversight, strict regulation of access to sensitive personal data, the right of taxpayers to be informed, and compensation mechanisms in cases of error.
