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.

Skatteetaten has replaced its old Altinn II phase-out timeline with a new service-by-service cut-off schedule running to the end of 2026Skatteetaten. The change appears on the cooperation-partner pages for regnskapsførere, revisorer and rådgivere and for systemleverandører, and on the a-melding reminder page about delegating new tilgangspakker.

Under the new schedule, Altinn II roles are being phased out towards 31 December 2026Skatteetaten. The Kontroll service stops working through Altinn II roles on 20 October. On 17 November the cut-off hits:

A-melding

Skattemelding for formue, inntekt og tilhørende tjenester (person og næring)Skatteetaten

Skattekort (person og næring)Skatteetaten

Skatteoppgjør for formue og inntekt (person og næring)Skatteetaten. Services not named under the earlier dates, and all remaining Altinn II roles, disappear entirely on 31 DecemberSkatteetaten.

The a-melding reminder page extends the deadline for payroll filers (previously old Altinn roles were to stay active only until 31.12.2025Skatteetaten): old single-service delegations in Altinn II are removedSkatteetaten, so businesses that previously held access to enkelttjenester in Altinn II must delegate new enkelttjeneste access or tilgangspakker as soon as possible to avoid interruptions to a-melding servicesSkatteetaten. Old Altinn roles stay active until 17 November 2026; anyone already on tilgangspakker needs to do nothingSkatteetaten.

The old timeline it replaces said submission via Altinn II ended 31 MaySkatteetaten, a-melding and skattekort via fagsystem had a last deadline of 15 June at 12:00Skatteetaten, Altinn II closed on 19 JuneSkatteetaten, and Altinn II roles disappeared entirely on 31 DecemberSkatteetaten.

Two standing nuances remain. Roles and the new tilgangspakker coexist in parallel through 2026Skatteetaten, but the continuation of Altinn roles applies only to those who fill in tasteskjema and upload attachments manually on skatteetaten.noSkatteetaten; anyone reporting through systems such as payroll software has needed tilgangspakker to report on the re-established services since 31 May 2026Skatteetaten. And since 19 June it has no longer been possible to delegate new access with Altinn II rolesSkatteetaten — access must instead be granted with tilgangspakkerSkatteetaten. Specialist roles for accountants and auditors convert to tilgangspakker automaticallySkatteetaten. The pages describe the change as part of Skatteetaten's move of its services to skatteetaten.no with Altinn 3 access packages, and point to Altinn's sites for further detail.

Check which Altinn II roles or old single-service delegations your business still uses for Kontroll, a-melding, skattemelding, skattekort and skatteoppgjør, and delegate the replacement tilgangspakker or enkelttjeneste access before the 20 October and 17 November 2026 cut-offs.
