SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve? Answering Czech tax questions correctly requires navigating income tax, VAT, tax procedure codes, decrees, and case law while tracking which version of a statute applies on a given date. This Skill provides a structured tax-advisor methodology and direct access to the CODEXIS legal database so answers are grounded in current legislation rather than memory. ## Core Features & Use Cases - Full tax analysis workflow: Classifies transactions, identifies all taxes in play (income tax, VAT, excise, property tax), checks special regimes and exemptions, and covers procedural duties under the Czech Tax Code. - CODEXIS database integration: Uses cdx-cli commands to search Czech legislation (CR), case law (JD), EU law, and commentaries, resolving exact statute versions and paragraph-level text. - Personal income tax deep-dive: A dedicated reference covers the six-layer DPFO workflow from income classification through deductions, rates, and tax credits. - Use Case: A user asks how the sale of an apartment is taxed for an individual; the Skill verifies residency and ownership period, pulls the current wording of the relevant Income Tax Act sections, checks exemptions, and delivers a cited answer with filing obligations. ## Quick Start Ask how a specific transaction or income is taxed in the Czech Republic and request the answer with citations to the current law.
