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.

The revised European Sustainability Reporting Standards and the new voluntary reporting standard are now law at EU level. Delegated Regulation (EU) 2026/1563 on the revised European Sustainability Reporting Standards (ESRS) and Delegated Regulation (EU) 2026/1560 on the standards for voluntary sustainability reporting (Voluntary Standard, VS) were published in the Official Journal of the European Union on 21 September 2026WPK.

The European Commission had adopted both regulations on 3 July 2026, and the European Parliament and the Council of the European Union raised no objections within the scrutiny period. As delegated regulations they apply directly and need no transposition into national law.

The revised ESRS regulation enters into force on 10 November 2026 and applies at the latest to financial years beginning on or after 1 January 2027WPK. It covers companies obliged to report on sustainability under the CSRDWPK — companies with more than 1,000 employees on average and turnover of more than 450 million EuroWPK. For financial years beginning between 1 January and 31 December 2026 the regulation offers three options: applying the previous ESRS as last amended, applying the revised ESRS, or applying the previous ESRS while using certain application reliefs from the revised ESRSWPK. The sustainability report must state which option was applied.

Separately, Delegated Regulation (EU) 2026/1560 introduces a Voluntary Standard for companies not subject to the CSRD reporting dutyWPK. It enters into force on 24 September 2026 and applies from that dateWPK. Its rules on the cap for the value chain (Value Chain Cap) apply for the first time to financial years beginning on or after 1 January 2027WPK.

The Commission had made targeted adjustments against the May 2026 consultation drafts based on EFRAG's Technical Advice, including further specifying the materiality principle, extending the transitional relief for reporting expected financial effects by another year, and aligning greenhouse-gas reporting more closely with international standards; an accompanying Staff Working Document explains the changes. For 2026 and 2027 reporting engagements, work from the published Official Journal texts rather than the July drafts.

Legal basis: Delegated Regulations (EU) 2026/1563 and (EU) 2026/1560, published in the Official Journal of the European Union on 21 September 2026.

For 2026 and 2027 reporting engagements, work from the published Official Journal texts of Regulations (EU) 2026/1563 and (EU) 2026/1560, and disclose the chosen FY 2026 option in the sustainability report.
