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.

An audit firm performing sustainability-reporting assurance must now appoint, alongside the lead engagement partner, an auditor licensed for sustainability-assurance activity who meets the impeccable-reputation requirementE TAR.E TAR The rule comes from Order No. V3-20 of 6 October 2026, issued by the Director of the Audit, Accounting, Property Valuation and Insolvency Management Service (AVNT), which restates point 19 of the work-organisation and internal-structure rules approved by Order No. V3-15 of 25 July 2024E TAR E TAR.

Under the new wording, an audit firm performing sustainability-reporting assurance appoints at least one key sustainability-assurance partnerE TAR, who may be the key audit partner or one of those partners. The firm must additionally appoint an auditor entitled to perform sustainability-assurance activity as stated in Article 21(1) of the Financial Statements Audit and Other Assurance Services Act (Įstatymas)E TAR, and meeting the impeccable-reputation requirement of Article 16 of that ActE TAR. Independence and competence remain the decisive selection criteria for the person named. An independent assurance provider appoints at least one assurance specialist responsible for performing the sustainability-reporting assurance.

Previously, point 19 of the V3-15 rules required only the key partner (for an audit firm) or the responsible assurance specialist (for an independent provider), chosen for independence and competence.E TAR The amendment adds the licensed-auditor and reputation conditions to the audit-firm side, and the final sentence now assigns the independent provider's duty to appoint its responsible specialist within the same point.

The rest of the framework is unchanged: the appointed persons must be given sufficient resources and competent staff, must actively participate in the engagement, and must devote enough time to it; the firm keeps per-client data including the names of the appointed persons and the fees set for assurance and other services. The amendment is a single-point restatement — it changes how audit firms staff assurance engagements, not the surrounding quality-control, file-keeping and reporting duties.

Legal basis: Order No. V3-20 of 6 October 2026 restating point 19 of the rules approved by Order No. V3-15 of 25 July 2024; the auditor-entitlement and reputation conditions inside point 19 refer to Articles 21(1) and 16 of the Financial Statements Audit and Other Assurance Services Act.

Where an audit firm performs sustainability-reporting assurance, appoint a licensed auditor meeting the reputation requirement alongside the key partner.
