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.

Re-code CEIDG and KRS entries from PKD 2007 to PKD 2025 by 31 December 2026

Stale entries face automatic re-coding by 31 January 2027 or deletion from CEIDG, ending ZUS payer registration; the accident-insurance rate from 1 April 2027 follows the PKD 2025 code on record at 31 December 2026.

Contribution payers entered in the Centralna Ewidencja i Informacja o Działalności Gospodarczej (CEIDG) or the Krajowy Rejestr Sądowy (KRS) whose entries still show PKD 2007 codes must replace them with PKD 2025 codes by 31 December 2026ZUS ZUS. The change is free: the payer files an application amending the register entry, choosing the new codes itself.

PKD 2025 has applied since 1 January 2025ZUS, and until 31 December 2026 the two classifications may be used side by sideZUS. From 1 January 2027 only PKD 2025 codes countZUS. Self-filing matters most where one PKD 2007 code maps to several PKD 2025 codes: the Główny Urząd Statystyczny (GUS) transition keys annexed to the PKD regulation drive the automatic re-codingZUS, and a machine match can miss the activity actually carried on. Entries that already show PKD 2025 codes still deserve a check that the codes match the business actually run.

Entries not updated by 31 December 2026 are re-coded automatically by 31 January 2027 wherever the keys allow itSejm; companies in the KRS are converted through the same automatic register procedureZUS. Where automatic conversion is impossible, CEIDG deletes the entry ex officio after 31 January 2027Sejm. That covers entries with empty, missing or unusable code fields that were never supplemented with PKD 2025 codes.

Deletion has a cascade. The deletion notice reaches ZUS systems without any action by the payerZUS and ends the payer's registration as a contribution payerZUS. It can also end registration as an insured personZUS, which puts benefit rights that depend on insurance coverage at riskZUS.

No parallel filing with ZUS is needed. Amendments filed in CEIDG or KRS reach ZUS automatically, since CEIDG transmits entry data to ZUS electronically. Re-coding does not require re-registering the business or its employees for social or health insurance, and it does not by itself change the contribution assessment base.

Correct codes also set the accident-insurance price. The predominant-activity type recorded in the REGON register decides the payer's activity groupSejm; the group rate, multiplied by the payer's individual correction index for payers with at least 10 insured persons, gives the accident contribution rateSejm, while smaller payers pay a flat 50% of the highest group rate. Rates apply per contribution year running from 1 April to 31 MarchSejm, and group membership is taken from the PKD entry in REGON on 31 December of the preceding yearSejm. So the rate for the year starting 1 April 2027 follows the PKD 2025 code on record at 31 December 2026ZUS — one more reason to fix entries before the deadline. Through the end of 2026 the group is still derived from PKD 2007 codes.

Legal basis: Rozporządzenie Rady Ministrów z dnia 18 grudnia 2024 r. w sprawie Polskiej Klasyfikacji Działalności (PKD) (Dz.U. z 2024 r. poz. 1936); ustawa z dnia 21 listopada 2025 r. o zmianie ustawy o statystyce publicznej oraz niektórych innych ustaw (Dz.U. z 2025 r. poz. 1792); ustawa z dnia 30 października 2002 r. o ubezpieczeniu społecznym z tytułu wypadków przy pracy i chorób zawodowych; rozporządzenie Ministra Pracy i Polityki Społecznej z dnia 29 listopada 2002 r. w sprawie różnicowania stopy procentowej składki.
