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 2027 general property assessment will use expanded valuation-factor ranges for småhusenheter under amendments to fastighetstaxeringsförordningen.Skatteverket The S-factor series for houses extends to 70.0, while the location-factor series for house plots extends to 12.0.Skatteverket Skatteverket SFS 2026:377 entered into force on 1 June 2026 and first applies at the 2027 general assessment.Skatteverket Skatteverket

The house valuation rules now provide 93 distinct value levels for the standard house, compared with 88 in the previous text. Values in the SV table are multiplied by the prescribed S-factor for the value area. The series still starts at 1.5 but now adds 62.0, 64.0, 66.0, 68.0 and 70.0 above the previous maximum of 60.0.Skatteverket

These factors are components of the valuation calculation. Under the ordinance’s formula, the relative value for the house’s size and standard is combined with the S-factor, the applicable age factor and the factor for property-law circumstances and value ranking. For advisers checking an assessment calculation, the extended series changes the available S-factors within that framework.

For land associated with houses, the FB table now contains 60 location factors instead of 56.Skatteverket The fixed series runs from 1.0 to 12.0, adding 10.5, 11.0, 11.5 and 12.0 beyond the previous ceiling.Skatteverket The factor for the normal plot remains 1.0. The table specifies factors for location classes 2 and 3, which concern proximity to shore, and class 4, which is neither shore nor near-shore.

The amended provision also expressly requires location class 1, the shore class, to use factors from the fixed series. The guideline-value specification must state the location factors for classes 1 and 2. Those requirements matter when matching a plot’s location classification to the factor used in its assessment.

The legal basis is fastighetstaxeringsförordningen (1993:1199), with 1 kap. 6 and 35 a §§ amended by SFS 2026:377 and its transitional provisions governing first application, alongside the valuation formula in 1 kap. 7 c §.Skatteverket

When checking a 2027 house assessment, confirm which S-factor and location factor were used: the S series now runs to 70.0 and the FB series to 12.0, with class 1 taking factors from the same fixed series.
