SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

Help CFOs and accountants reliably calculate, check and optimize French corporate taxes and tax credits while reducing risk of misfiling and audit exposure. The skill centralizes rules and checklists for IS, TVA, CIR/CII, transfer pricing and common deductibility pitfalls so teams avoid last-minute surprises at monthly and year-end closings.

Core Features & Use Cases

  • IS simulation & optimization: run acomptes, solde and apply PME reduced rate logic, amortissement strategies and provisions reconciliations.
  • TVA regime & CA3/CA12 checks: verify balance vs declared CA3, flag inconsistencies and suggest regularisations.
  • CIR / CII estimation: estimate eligible R&D and innovation credits and generate a dossier template for justification.
  • Transfer pricing guidance & documentation checklist: identify transactions requiring Master/Local file and CBCR thresholds.
  • Use case: prepare an IS reconciliation and CIR dossier for a SME ahead of tax-filing, with automatic warnings for non-deductible items and documentation gaps.

Quick Start

Analyze the company's fiscal year using private/company.json and the balance file to estimate IS, check TVA coherence, run a CIR eligibility estimate, and produce an IS reconciliation and templates.
