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.

Skatteverket will close its older Inkomstdeklaration 2 e-service on 29 December 2026.Skatteverket Companies, economic associations and the accounting firms helping them can already use other digital filing routes.Skatteverket The closure concerns the service that accepts the return’s first page, with the remaining parts and attachments sent separately on paper.

The combined Inkomstdeklaration 2, 3 och 4 service accepts the complete corporate return, including Räkenskapsschema (INK2R), Skattemässiga justeringar (INK2S), supported attachments and additional information. Skatteverket says it can be used for financial years ending in January 2024 or later.Skatteverket Preparers need to complete the return in one session because the information is not saved in the service.

Tax software is another route where the program supports submission to Skatteverket. After following the software’s instructions, an authorised representative signs the return on Mina sidor. Alternatively, software that produces SRU files can be used with Filöverföring. That route produces a receipt for the transferred files, followed by signing on Mina sidor and a receipt for the signed return.

For these digital corporate-return routes, the person signing can be a registered declaration agent, a managing director registered with Bolagsverket, or a registered signatory entitled to sign aloneSkatteverket. Preparers should align the chosen route with the client’s signing arrangements. Skatteverket expressly asks taxpayers receiving accounting assistance to agree the filing method with their adviser.

The older service’s availability table distinguishes financial-year groups: returns for years ending September–December 2025 remain accessible there through 3 December 2026Skatteverket, while the January–August 2026 group is shown through 29 December 2026Skatteverket. These are service-availability datesSkatteverket; the authority separately lists filing deadlines according to when the financial year ends.

For affected firms, the practical preparation is to select the digital route, ensure the full return can be submitted and arrange its signature before relying on the old channel for further filings.

The source is Skatteverket’s corporate-return and accounting-firm service guidance announcing the withdrawal and describing the available filing routes.

Move corporate returns to the combined Inkomstdeklaration 2, 3 och 4 service or a filing-capable program before 29 December 2026, and confirm who is authorised to sign on Mina sidor.
