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.

Ilmoitin.fi adds 2026 business returns in its 22 September release

The upgrade brings a 07:00–09:00 outage for Ilmoitin.fi and ApitamoPKI, plus next-year prepayment data transfers; submitted files can no longer be opened from the production archive.

Ilmoitin.fi will support checking and sending tax-year 2026 income tax returns for personal businesses using forms 2, 2Y, 2C, 5, 6A and 7KVero in its release scheduled for 22 September 2026Vero. Vero says both the Ilmoitin.fi website and the ApitamoPKI interface will be unavailable during the version update, approximately 07:00–09:00 that dayVero.

The release also introduces the next year's prepayment direct transfersVero. Under its heading for 2027 prepayment, Vero lists resident pension recipients' transfers (VKESSELE), non-resident pension recipients' transfers (RVKSSELE), wage withholding information (VKESSPAE), and YEL and MYEL earned-income information (VKTYOSVA). These are the data flows identified for checking and submission in the release notice.

There is a year discrepancy to watch in the VKTYOSVA item: the release notice's individual bullet says 2076, although its section heading says 2027. Vero's separate record-description list identifies the VKTYOSVA version as 2027.

Vero says the direct-transfer example files have been updated. Its Esimerkkiaineistot page lists 2027 examples for VKESSELE, RVKSSELE and VKESSPAE.

A separate operational change has already been made in production: a submitted file can no longer be opened from Ilmoitin's archiveVero. The service remains designed for sending files produced by software in accordance with the record descriptions; it does not provide online forms to fill in.

Ilmoitin also offers a test environment accessible with test credentials. Vero warns that returns sent under the same test credentials are visible in the archive to everyone using those credentialsVero, and says not to use production material in the test environment. That limitation matters when testing the new reporting formats with shared test identities.

The service also allows attachments to software-generated returns and checks whether a return file has the correct format. Authentication and authorisation requirements are set out by data flow on Vero's Tunnistustavat, valtuudet ja edustusoikeudet page. The general service guidance directs users there to check the requirements for submitting their particular returns.

Prepare the listed 2026 business-return formats for the 22 September release and account for the announced Ilmoitin.fi and ApitamoPKI outage at approximately 07:00–09:00.
