What sources does Taxxa search?

Taxxa searches a continuously updated collection of more than one million pages from tax authorities, government publications, legislation and case law across the European jurisdictions it covers. Every response cites the underlying material, so a professional can inspect the rule, its jurisdiction and whether it is current before relying on the result.

Can Taxxa work with a team’s own documents?

Yes. Research can combine the public knowledge base with a team’s own PDF, DOCX, CSV and TXT files in one workspace. That makes it possible to compare a client document with the relevant guidance, trace a conclusion to its source and prepare a draft without losing the evidence that supports it.

Who is Taxxa built for?

Accountants, auditors, tax advisors, payroll specialists, bookkeepers and advisory teams working across European jurisdictions. Shared workspaces keep research available to colleagues, and citations make review easier.

Where is customer data stored, and is it used to train models?

Customer data stays in the European Union and is never used to train language models.

Does Taxxa replace professional judgement?

No. Taxxa is a research and drafting workspace. It helps professionals reach an informed starting point faster; the professional still reviews the evidence and makes the final decision. It does not file returns, post bookkeeping entries or give legal advice.

Providers of high-risk AI systems can now rely on a harmonised European standard for their quality-management duties.Europa Commission Implementing Decision (EU) 2026/2274Europa of 12 October 2026Europa, published in the Official Journal on 14 October 2026Europa, publishes the reference of EN 18286:2026Europa, entitled "Artificial intelligence – Quality management system for EU AI Act regulatory purposes". The standard was drafted by CEN and Cenelec under the standardisation request in Implementing Decision C(2025) 3871 and covers quality management systems for providers of AI systems, including post-market monitoring processesEuropa.

The publication matters because of the presumption of conformity in Article 40 of Regulation (EU) 2024/1689Europa (the Artificial Intelligence Act)Europa. High-risk AI systems that conform to a harmonised standard whose reference has been published in the Official Journal are presumed to conform to the requirements of the Act that the standard covers.Europa A provider whose quality-management system follows EN 18286:2026 therefore benefits from that presumption for the quality-management requirementsEuropa, rather than having to demonstrate compliance by other means.

Those requirements sit in Article 17 of the Artificial Intelligence ActEuropa, which obliges providers of high-risk AI systems to put in place a documented quality management systemEuropa with at least thirteen listed elements. They include a regulatory-compliance strategy, design and development controls, examination and testing procedures, data-management systems, the risk-management system of Article 9, a post-market monitoring system in accordance with Article 72, serious-incident reporting procedures under Article 73, record-keeping, resource management and an accountability framework. Article 72 in turn requires providers to establish and document a post-market monitoring system that actively collects and analyses performance data over the system's lifetime, based on a post-market monitoring plan forming part of the technical documentation.

The presumption applies only to the extent the standard covers the requirement concernedEuropa, and only from the date the reference was publishedEuropa. Providers already subject to quality-management obligations under sectoral Union law may integrate the Article 17 elements into those existing systems, and providers that are financial institutions subject to internal-governance rules under Union financial-services law are deemed to fulfil the quality-management obligation, except for the risk-management, post-market monitoring and incident-reporting elementsEuropa. The Decision itself entered into force on the day of its publication.Europa

Legal basis: Commission Implementing Decision (EU) 2026/2274 publishing EN 18286:2026; Articles 17, 40 and 72 of Regulation (EU) 2024/1689.

Align your quality-management system and post-market monitoring procedures with EN 18286:2026 to benefit from the presumption of conformity.
