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.

Finnish companies can now subscribe to PRH's Ilmoitusvahti monitoring service online instead of ordering it on a paper formPRH, and the revised guidance sets out who can subscribe and how. The change matters to board members, managing directors and partners who want alerts about filings made in their company's name — a front-line defence against register fraud.

The default route is unchanged: report the company's email address to the Trade Register (kaupparekisteri) via the YTJ service — free of chargePRH — and PRH emails the company when a change notification is filed, provided the address is registered and functionalPRH. Note that the registered email address is public information, visible in the YTJ company search and other company-information services.

The alternative for those who do not want to register a company email address is Ilmoitusvahti in PRH's Virre servicePRH. The paper-form order is gonePRH; subscription is now done online. Eligibility is explicit: only a person registered in the Trade Register as the company's responsible person (vastuuhenkilö) — for example a board member, managing director or partner (yhtiömies) — can subscribePRH. The steps are: log in to Ilmoitusvahti, select the company whose notifications you want to follow, add the email address or addresses for the alerts, save and log out. Logging in requires a Finnish personal identity code (henkilötunnus) and one of the Finnish identification methods offered by Suomi.fi identification, such as personal online banking codes or a mobile certificate (mobiilivarmenne)PRH. The service suits companies with no registered email address, or responsible persons who want the alerts to a personal inbox — multiple addresses can be added.

When an alert arrives, the recipient checks the filing's exact details in the Virre service. If the details suggest someone filed in the company's name without authorisation, the guidance says to contact the Trade Register advisory service (kaupparekisterin neuvonta) immediately. The page also points to PRH's anti-fraud material and to the instructions for checking one's own registered personal data, now expressly including one's current responsible-person roles in companies.

Legal basis: PRH guidance page Näin seuraat yrityksesi tietojen muutoksia kaupparekisterissä, current version; Ilmoitusvahti subscription via Virre with Suomi.fi identification.
