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 financial institutions filing FATCA, CRS and DAC2 annual reports face a hard cutover: CRS/DAC2 reports on the current (old) schema can be filed only until 30 October 2026Vero, after which the Ilmoitin.fi service is temporarily unavailable for CRS/DAC2 annual reportsVero. A new schema applies from 1 January 2027, including corrections and reports for earlier yearsVero, and the replacement annual report (korvaava vuosi-ilmoitus) is abolished for both CRS/DAC2 and FATCA from the 2026 reports onwardsVero.

Vero has published a new CRS/DAC2 technical application guide (tekninen soveltamisohje) taking effect on 1 January 2027Vero, reflecting the new CRS schema. The structures, elements and Ilmoitin checks under that guide are live in the Ilmoitin.fi test environment, with submission, from 3 November 2026Vero, and in production from 1 January 2027Vero. The schema change affects reports for 2026 onwards: during calendar year 2026 CRS/DAC2 reports are still filed on the old schemaVero, and from 1 January 2027 everything, including corrections for earlier years, uses the new schemaVero. Financial institutions should therefore plan filing and correction traffic around the service pause after 30 October 2026 and validate their files in the test environment from 3 November. The most material element changes concern Self-Certification, AccountTreatment and AccountType, including a new report on whether the institution holds an explicitly valid self-certification, and reporting of a decedent's estate moving from entity account to joint account.

The correction procedure changes with the schema: the replacement annual report is no longer usedVero, and errors are corrected under the correction procedure defined by the OECD and the IRSVero. A separate CRS/DAC2 act (1042/2025) entered into force at the start of 2026Vero, with an updated in-depth CRS/DAC2 guide still to come.

Separately, Vero holds its annual FATCA, CRS and DAC2 information session on 4 November 2026Vero, with a pre-event survey open until 18 October 2026Vero.

Legal basis: CRS/DAC2 act (1042/2025); new CRS/DAC2 technical application guide effective 1 January 2027; OECD/IRS correction procedure for errors from the 2026 reports.

File any remaining old-schema CRS/DAC2 reports before 30 October 2026, validate new-schema files in the Ilmoitin.fi test environment from 3 November, and switch corrections to the OECD/IRS procedure instead of the replacement annual report.
