🇷🇴 RoTaxViz: Romanian LLC Fiscal Simulator (2025/2026)

RoTaxViz is a financial visualization engine designed for Romanian business owners operating through an LLC (SRL). It provides a real-time comparison between standard (10%) and speculative (16%) dividend tax scenarios, helping entrepreneurs navigate complex fiscal changes.

Core Simulation Parameters

The application assumes a standard Micro-company setup to ensure calculation accuracy:

  • Mandatory Employment: 1 person employed at the 2025 minimum wage (4,050 RON).
  • Professional Services: Fixed local accountant fees of €100 + VAT.
  • Fiscal Regime: 3% Corporate Income Tax (Micro-company status).
  • Health Insurance: Automatic tiered CASS calculations (6/12/24 wage thresholds).

📸 Interface Overview

📊 How it Works (The Logic)

The application follows a rigorous fiscal pipeline to ensure accuracy against 2025 Romanian regulations.

🔄 The Fiscal Pipeline

  1. Currency Normalization: Market EUR/RON rates are fetched via API, with a 1% "banking spread" applied to simulate real-world conversion costs.
  2. Corporate Layer: 3% Corporate Income Tax is applied to Gross Revenue.
  3. Operating Expenses (OpEx):
    • Accountancy: €100 + 21% VAT (VAT is treated as neutral/deductible).
    • Employment: Total cost of 4,050 RON (~€810) for one mandatory employee.
  4. Dividend Layer: Net Profit is calculated, and then the selected dividend tax (10% or 16%) is applied.
  5. Social Layer (CASS): Annualized profit determines which of the three health insurance tiers is triggered.
