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.

Pluriactivity certificates now valid 24 months, Urssaf says

Urssaf announced on 9 October 2026Urssaf that the durée of the certificat de mobilité internationale for pluriactivité situations rises from 12 monthsUrssaf to 24 monthsUrssaf for certificates issued from 8 October 2026Urssaf.

Pluriactivité means an employee working foreseeably, alternately or simultaneously between France and one or more other countries — in the European Union or in Norway, Switzerland, the United Kingdom, Iceland and Liechtenstein — typically combining employee and self-employed activity. The certificate records that situation and lets the employer declare the pluriactive employee's social contributions appropriately; in a posting situation the employee may continue to be covered by the French Sécurité sociale subject to conditions.

Certificates already in force keep their 12-month duréeUrssaf: only certificates issued since 8 October 2026 may run for 24 monthsUrssaf. For renewal mechanics, the employer renews from the online urssaf.fr account, at the earliest 30 days before the current certificate expires and at the latest on its last day of validity, past which a fresh request is needed rather than a renewal. Renewal is available only where the employee works under conditions identical to the initial request — same employee and company details, same activity, same country of work — and any change requires a new certificate request.

The request itself runs through the employer's online account under "Travailler à l'étranger", for one employee or a group: group requests require the same establishment (same Siret), the same destination country in the European Economic Area or Switzerland, a preserved hierarchical link (contract, salary, authority) with the company, and French social-security affiliation during the 30 days before the posting starts. After checking the summary the employer signs online ("Je signe ma demande"); if accepted, a same-day notification allows downloading the certificate from the dashboard's request list, with the Mobilité internationale adviser able to ask for supplements by email or telephone where the file needs closer review. A mission may still be cancelled even before it starts, within 15 days of the certificate request, or its end date brought forward from the dashboard.

Employers apply through the Mobilité internationale service page; certificates already running keep 12 monthsUrssaf.

Legal basis: Urssaf news of 9 October 2026, "Travail à l'étranger : les certificats de pluriactivité désormais valables 24 mois"Urssaf; Urssaf employer guides for requesting and renewing the certificat de mobilité internationale; no official-journal publication located for the underlying measure.

Employers of pluriactive staff should request new certificates through the Mobilité internationale service to get the 24-month validity, leave running 12-month certificates alone, and renew only where working conditions are unchanged.
