Polish statutory terms on this page (sprawozdanie finansowe, uchwała, CRBR, KSeF, e-Doręczenia…) stay in Polish on purpose — they are the names you will meet in the law and in the registers. Each one is explained in the glossary.
This is Foka’s informational calendar built from the provisions of Polish law: every deadline stands on a provision whose wording we machine-check against the consolidated text of the act. It is not legal or tax advice in your case; the obligations and deadlines remain the responsibility of the zarząd (management board).
Foka Firma shows the obligations and deadlines that follow directly from Polish law — each one stands on an act, an article and a literal quote. This is not tax or legal advice and it is not an assessment of your case: Foka will not tell you how much to pay in your situation, whether an exemption applies to you, or how to structure your taxes. Individual tax advice is reserved by law for a licensed doradca podatkowy (tax adviser), and legal advice for a radca prawny or adwokat. Before deciding, check the provision in the consolidated text of the act — every obligation links to it.
