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.

The CMA suspects Meta's platform terms may impose unfair trading conditions on dependent businesses; it will first test dominance, then abuse, gathering evidence into January 2027.

The Competition and Markets Authority has opened a Chapter II investigation under the Competition Act 1998GOV into suspected breaches of competition law by MetaGOV. The investigation, launched on 30 October 2026GOV, concerns Meta's commercial terms for businesses that use its platforms and servicesGOV. The CMA is concerned that requiring businesses to accept these terms may amount to the imposition of unfair trading conditions on businesses that rely on Meta's services to reach customers and audiences.GOV

The businesses under investigation are Meta Platforms, Inc., Facebook UK Limited and Facebook Ireland Limited.GOV The case page notes that the investigation may also concern other entities within Meta's corporate group, including relevant UK subsidiaries.

The investigation will assess two questions in sequence. First, whether Meta holds a dominant position in one or more relevant markets in the United KingdomGOV. Second, if it does, whether its existing commercial terms — or revisions to those terms — amount to an abuse of that position under Chapter II of the Competition Act 1998GOV. That framing tracks the statute: section 18 prohibits conduct amounting to abuse of a dominant position where it may affect trade within the United KingdomLegislation, and section 18(2)(a) expressly lists directly or indirectly imposing unfair purchase or selling prices or other unfair trading conditions among the conduct that may constitute such abuse. As part of the inquiry the CMA will gather and assess evidence from Meta and from affected third parties.

The published case timetable runs rapid initial information gathering and engagement with Meta and third parties from October 2026 to January 2027, with the investigation itself opened on 30 October 2026. The CMA cautions that these dates are indicative and may change.

No assumption should be made at this stage that competition law has been infringed, and no decision has been made on whether Meta has broken competition law. Following its initial investigation and information gathering, the CMA may close the investigation if it decides not to proceed. If it provisionally considers that competition law has been infringed, it may issue a statement of objections setting out its concerns and give the parties an opportunity to respond before reaching a final decision. The case page points to the CMA's guidance on Competition Act 1998 investigations for its procedures.

Businesses and advisers with relevant information can engage directly: the page invites anyone with information relevant to the investigation to contact the case team, naming a Project Director, an Assistant Project Director and a Senior Responsible Officer with their email addresses.

Legal basis: Competition Act 1998 Chapter II (section 18) and the CMA case page on suspected abuse of a dominant position in relation to Meta's commercial terms.

If your business contracts on Meta platforms or you advise those who do, assess exposure to the terms under scrutiny and consider submitting relevant evidence to the CMA case team during the information-gathering window.
