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.

Forhåndsmelding transition drops Utfyller/Innsender

Regnskapsmedarbeider and Post/arkiv remain as legacy routes; staff who filed via Utfyller/Innsender need an Enhetsregisteret role or a delegation to the single service or a listed package.

Industry: Construction

The developer must ensure Arbeidstilsynet receives advance notice of temporary or mobile construction work lasting more than 15 working days or exceeding 250 person-days. Notice goes on the prescribed electronic form no later than one week before work starts. Where the developer is a consumer, the contractor undertaking the work must submit it instead. The notice must be kept updated, and the developer must print the confirmation poster received in the Altinn inbox and display it prominently on site.

The form is filed by the developer for each qualifying site, with an amendment notice for cancellations and duration changes made by reopening the submitted notice in the inbox or archive. A private individual can no longer file: since June 2026 the filer must represent a business. The notice collects the transmission date, exact site address, project nature, identities and contact details of the developer, its representative and the coordinators, the designation and organisation numbers of designers and contractors, plus expected start, duration, peak staffing and the planned number of undertakings.

To complete and submit the notice in Altinn, the filer needs a role in the Enhetsregisteret or a delegation — either to the single service or to one of the Byggesøknad, Oppføring av bygg og anlegg or Tjenester NUF packagesAltinn. Receiving mail, replies and the poster in return requires the Ordinær post til virksomheten and Arbeidstilsynet - meldinger packages. The help page on obtaining delegations remains the place to arrange access.

During the transition period, filers who already hold a legacy Altinn role may still use the formAltinn. That list now contains Regnskapsmedarbeider and Post/arkivAltinn. Until this change it also contained Utfyller/InnsenderAltinn, so staff who filed through that role must now hold an Enhetsregisteret role or a current delegation insteadAltinn.

Legal basis is byggherreforskriften § 10 on advance notice of construction sites, filed as Forhåndsmelding av arbeidsplass through Arbeidstilsynet in Altinn.

Move site-notice filing off Utfyller/Innsender to an Enhetsregisteret role or a delegation, and submit each qualifying site no later than one week before work starts.
