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.

CMA launches Phase 1 inquiry into Vivisol / Air Liquide deal

The Competition and Markets Authority has launched its Phase 1 merger inquiry into the Vivisol / Air Liquide home oxygen services business transaction, announcing the launch by notice to the parties on 24 September 2026. A commencement notice dated 24 September 2026 is published alongside the announcement. The statutory timetable sets 19 November 2026 as the deadline for the Phase 1 decisionGOV, although the CMA notes it will seek to determine its investigation as quickly as possible and that the statutory deadline can be extended in certain limited circumstances.

Interested parties — including competitors, customers and suppliers of home oxygen services — have until 1 October 2026 to submit initial viewsGOV. The invitation to comment, which runs from 11 August 2026 to 1 October 2026, is the first part of the CMA's information-gathering process: it allows interested parties to submit views on the impact the transaction could have on competition in the UK. Written representations about any competition issues should be provided by the deadline set out in the timetable.

The timetable firms up what was previously provisional. The case page formerly listed the Phase 1 decision deadline and the inquiry launch as TBC, with the invitation to comment closing in late September 2026, and stated that the CMA had not yet launched its formal investigation into the transaction. On pre-notification, the page records that the CMA has received the necessary information from the parties to commence pre-notification.

Representations should be sent to vivisol.airliquidehomeoxygen@cma.gov.uk, and the page now names a principal case officer, Hannah Street. Anyone submitting views should expect the CMA to use their name and contact details as personal data: the authority processes them so it can contact contributors again for further help or information in order to carry out its merger work under Part 3 of the Enterprise Act 2002, with further detail in its personal information charter.

Legal basis: Enterprise Act 2002 Part 3.

Send written representations on the Vivisol / Air Liquide transaction to vivisol.airliquidehomeoxygen@cma.gov.uk by 1 October 2026.
