PFA Fiscal Skill

pfa-fiscal is an AI assistant skill for estimating annual Romanian PFA taxes for a Persoană Fizică Autorizată working in sistem real.

It calculates:

  • Impozit pe venit: 10%
  • CAS: pension contribution, 25% on the applicable capped base
  • CASS: health contribution, 10% using the fiscal-year-specific model
  • Total taxes
  • Estimated take-home income

The skill is designed for Romanian freelancers, consultants, and self-employed professionals who want a clear breakdown of their annual fiscal obligations.

This skill is informational only. For official tax filing, Declarația Unică, or edge cases, consult an accountant or ANAF.

What The Skill Does

The skill asks for or uses:

  • Fiscal year
  • Gross income, venit brut
  • Deductible expenses, cheltuieli deductibile
  • Confirmed Romanian minimum gross salary for that year

It then computes:

Venit net = Venit brut - Cheltuieli deductibile

Then it calculates:

  1. CAS
  2. CASS
  3. Impozit pe venit
  4. Total taxe
  5. Venit rămas

The output includes formulas, tax brackets, thresholds, and a final summary table.

Example Prompt

Calculează taxele PFA pentru 2025.

Venit brut: 120.000 RON
Cheltuieli deductibile: 20.000 RON
Salariu minim lunar: 4.050 RON

Example Output

Venit net = 120.000 - 20.000 = 100.000 RON

CAS:
Venit net >= P24
Baza CAS = 97.200 RON
CAS = 25% × 97.200 = 24.300 RON

CASS:
Venit net >= P24
Baza CASS = 97.200 RON
CASS = 10% × 97.200 = 9.720 RON

Impozit pe venit:
Baza = Venit net - CAS
Baza = 100.000 - 24.300 = 75.700 RON
Impozit = 10% × 75.700 = 7.570 RON

Total taxe = 41.590 RON
Venit rămas = 58.410 RON
