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.

ICS2 filers must report own-system outages to Estonian customs desk

If your own ICS2-linked system goes down and it hits ICS2 operations, you or your authorised IT provider must report it to Maksu- ja Tolliamet at EEservicedesk@emta.ee under the continuity guide.

The Tolliinfosüsteemide kasutajatele instructions now state an explicit outage-notification duty for ICS2 filers in Estonia and the IT providers they authoriseEmta Emta: Kui kliendi ICS2-ga seotud süsteem ei ole kättesaadavEmta ning katkestus mõjutab ICS2-ga seotud toimingute teostamistEmta, peab klient või tema volitatud IT-teenuse osutaja teavitama katkestusest Maksu- ja TolliametitEmta vastavalt juhendis „ICS2 Business Continuity Plan for Economic Operators“ sätestatud korraleEmta — notification goes to the e-mail address EEservicedesk@emta.eeEmta.

The duty sits inside the existing continuity framework for entry summary declarations. Where the ICS2 system or one of its components suffers a technical outage, the Business Continuity Plan — the asendustoiming — applies, with the aim of keeping safety and security data flowing even while a component is temporarily unavailable. Where an ICS2 central component is unavailable, filers follow the ICS2 BCP guidance for whichever component the outage affects. Information on an ICS2 outage or BCP activation is transmitted over ICS2/STI-STP and on Maksu- ja Tolliamet's planned-outages page for EU customs information systems, and the BCP guides are available on the ICS2 – Andmekogu page.

The added passage addresses the case the surrounding section left open: ICS2 süsteemi või selle üksikute komponentide tehnilise katkestuse korral rakendatakse Business Continuity Plan'i (BCP) ehk asendustoimingut, whereas the new sentences impose the duty where the client's own linked system is down — Kui kliendi ICS2-ga seotud süsteem ei ole kättesaadav — and the notification follows the procedure vastavalt juhendis „ICS2 Business Continuity Plan for Economic Operators“ sätestatud korrale. For ordinary filing errors, the page keeps a separate passage: where an ENS submission fails, the filer saves the draft, then sends the error description with the saved draft file to the same EEservicedesk@emta.ee address for helpEmta. Entry summary declarations remain available in the ICS2 system for 30 daysEmta, so successfully filed ENS files should be saved locally for later reuse.

ENS declarations are rejected where the submitted data quality is insufficientEmta; filers must watch their error messages and re-submit with corrected data. A list of prohibited goods descriptions — the stoppsõnade list — is available in CIRCABC. Declarations filed with data arriving from NCTS for T1/ALD documents are exempt from the prohibited-description validation in NESEmta, and neither the consignee nor the consignor identification number recorded on them is checked in NESEmta.

Legal basis: the new outage-notification passage of the Tolliinfosüsteemide kasutajatele instructions, applying the ICS2 Business Continuity Plan for Economic Operators guide.

If your ICS2-linked system goes down and the outage affects ICS2 operations, notify Maksu- ja Tolliamet at EEservicedesk@emta.ee under the Economic Operators continuity guide instead of waiting for a central-system notice.
