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.

BZSt posts final DAC8/CARF dataset and five XML filing samples

Crypto-asset service providers reporting to the Bundeszentralamt für Steuern (BZSt) can now build and test their DAC8/CARF filings against five published sample XML files covering first reports, corrections, nil returns and cross-border nexus casesBzst. The samples sit alongside the XSD dataset for exchange over the mass-data interface, whose download entry has lost its 'Entwurf' (draft) labelBzst; the officially prescribed dataset description itself has been binding since its announcement in the Bundessteuerblatt on 14 January 2026Bzst.

The first-report sample (Erstmeldung CARF701, new data, OECD1) shows a reporting provider (RCASP) with two different crypto-asset users: one natural person (Individual) and one non-natural person (Organisation) that additionally has a controlling person (ControllingPerson). It is the template for a complete new-data filing with both user types and a controlling-person structure in one message.

Two follow-up samples cover corrections. One Folgemeldung (CARF702, corrected CAU data, OECD0 and OECD2) shows a provider whose own information is unchanged (OECD0) with a correction to the NumberofUnits element for one crypto-asset user. The other Folgemeldung (CARF702, corrected and deleted data, OECD2 and OECD3) shows a provider whose address information changed (OECD2), one crypto-asset user that is deleted (OECD3), and another user whose address information likewise changed (OECD2). Together they demonstrate how to flag unchanged records, amend figures and addresses, and remove a user record.

The nil sample (Nullmeldung CARF703) shows a reporting provider (OECD1) with no reportable DAC8/CARF information for the reporting period. Providers with nothing to report still have a defined message for that outcome. The OtherNexus sample (CARF701) shows a reporting provider (OECD1) with a higher-value nexus in a state other than Germany, notifying that it meets its reporting and due-diligence duties in that state.

The underlying duties come from the Kryptowerte-Steuertransparenz-Gesetz (KStTG)Bzst of 22 December 2025Bzst, in force since 24 December 2025Bzst, which transposes Council Directive (EU) 2023/2226 (DAC8) into German lawBzst. Providers report annually by 31 July for the preceding calendar-year reporting periodGesetze IM Internet, electronically using the officially prescribed dataset over the officially designated interfacesGesetze IM Internet; the prescribed dataset and interface were announced in the Bundessteuerblatt on 14 January 2026Bzst and the published description is bindingBzst. Where a filing was omitted or proves defective, the provider must complete or correct it without delay once the gap or error is known.Gesetze IM Internet The duties apply for the first time to calendar year 2026Gesetze IM Internet, so 2026-period reports fall due by 31 July 2027Bzst. The BZSt notes that no changes to the dataset description are currently required under the EU specification.

Legal basis: Kryptowerte-Steuertransparenz-Gesetz (KStTG) of 22 December 2025, transposing Council Directive (EU) 2023/2226 amending Directive 2011/16/EU.

Validate reporting software and filing workflows against the five sample XML files and the binding XSD dataset before the first 2026-period reports fall due.
