Before computing, you MUST know:
If activity type and autonomous organisation status are unknown, STOP. IRAP liability depends on these.

Situation: Avvocato (lawyer) working alone from home with a laptop and phone. Resolution: Likely NO autonomous organisation. IRAP exempt per Cassazione Sezioni Unite 9451/2016. Document the factual basis (no employees, no significant beni strumentali).
Situation: Architect with one part-time employee (segretaria). Resolution: Having even one employee generally constitutes autonomous organisation. IRAP likely applies. [T2] -- confirm with case law. Some case law allows an exception if the employee's role is merely administrative and marginal.
Situation: Client is under regime forfettario (flat-rate tax regime). Resolution: IRAP exempt. No declaration, no payment. Forfettario exclusion is clear and absolute.
Situation: Impresa individuale operating a retail shop with two employees. Resolution: IRAP applies. This is an impresa (business), not a profession. Autonomous organisation test is not relevant for imprese -- they are always subject.
Situation: Client has business activity in both Lombardia and Campania. Resolution: IRAP must be apportioned between regions based on where value is produced (typically by employee/payroll location). Each region's rate applies to its portion. [T2] -- confirm apportionment methodology.
Situation: Client asks if IRAP reduces income tax. Resolution: 10% of IRAP paid is deductible from IRPEF taxable income. Additionally, the portion of IRAP on employee costs (cuneo fiscale deductions) is fully deductible from IRPEF base.
Situation: New impresa individuale, started in April 2025. Resolution: IRAP applies from the first year of activity (no first-year exemption like CFE in France). Advance payments based on forecast method (no prior year). First payment with saldo by 30 June 2026.
Situation: Client closes business in August 2025. Resolution: IRAP applies on valore della produzione for the period of activity (Jan-Aug). Final declaration due by 30 November 2026. No advance payments for the following year.
Situation: Client was contribuente minimo (exempt) and switches to ordinary regime. Resolution: IRAP applies from the year of regime change. The autonomous organisation test applies if the client is a professional. [T2] -- assess organisation status.
Input: Freelance consultant, works alone, home office, EUR 80,000 fees, EUR 15,000 costs. Expected output: IRAP = EUR 0. Exempt -- no autonomous organisation.
Input: Dentist with 2 employees, studio rental, EUR 200,000 fees, EUR 60,000 deductible costs, EUR 40,000 employee costs. Expected output: VPN = EUR 200,000 - EUR 60,000 + EUR 40,000 = EUR 180,000. Less employee deductions (assume EUR 15,000): EUR 165,000. IRAP = EUR 165,000 x 3.90% = EUR 6,435.
Input: Retail business, revenue EUR 300,000, production costs EUR 200,000, labour EUR 50,000, interest EUR 5,000. Lombardia. Expected output: VPN = EUR 300,000 - EUR 200,000 + EUR 50,000 + EUR 5,000 = EUR 155,000. Less employee deductions (assume EUR 20,000): EUR 135,000. IRAP = EUR 135,000 x 3.90% = EUR 5,265.
Input: Auto-entrepreneur equivalent, regime forfettario, EUR 50,000 revenue. Expected output: IRAP = EUR 0 (exempt).
Input: Professional with organisation in Campania, VPN EUR 100,000. Expected output: IRAP = EUR 100,000 x 4.82% = EUR 4,820.
Input: Prior-year IRAP = EUR 8,000. Expected output: 1st acconto (30 June) = EUR 8,000 x 40% = EUR 3,200. 2nd acconto (30 November) = EUR 8,000 x 60% = EUR 4,800.
Input: Prior-year IRAP = EUR 40. Expected output: Below EUR 51.65 threshold. No advance payments required. Only saldo due.

Valore della produzione netta (imprese individuali)
valore_produzione_netta = ricavi (revenue) + variazioni rimanenze (inventory changes) + altri proventi (other operating income) - costi della produzione (production costs) + costo del lavoro (labour costs added back) + interessi passivi (interest added back) + compensi occasionali (occasional compensation added back)D.Lgs. 446/1997, art. 5-5bis
Key difference from income tax base
IRAP base is NOT the same as income tax base. Labour costs, interest, and some other items are added back.D.Lgs. 446/1997, art. 5-5bis
Valore della produzione netta (professionals)
valore_produzione_netta = compensi (fees/revenue) - costi inerenti (deductible costs) + costo del personale (employee costs added back)D.Lgs. 446/1997, art. 5-5bis
Simplified computation option
Businesses that opt for simplified accounting (contabilità semplificata) can compute IRAP on the difference between revenue and costs as reported for income tax, with specific add-backs.Art. 5-bis
Verify IRAP liability logic
IF regime_forfettario OR contribuente_minimo: IRAP = 0 (EXEMPT) ELIF lavoratore_autonomo AND no_autonomous_organisation: IRAP = 0 (EXEMPT) ELSE: proceed to calculation
Compute VPN logic
# For sole proprietor (impresa): vpn = revenue + inventory_changes + other_income - production_costs + labour_costs_addback + interest_addback # For professional (autonomo with organisation): vpn = fees - deductible_costs + employee_costs_addback
Apply deductions logic
# Deduction for employees (deduzione per dipendenti) # Various cuneo fiscale deductions for permanent employees vpn_adjusted = vpn - employee_deductions
Apply regional rate logic
IRAP = vpn_adjusted × regional_rate (typically 3.90%)
Deductions from IRAP itself
A portion of IRAP attributable to labour costs is deductible from IRPEF/IRES: - 10% of IRAP paid is deductible from income tax base (as per D.L. 201/2011) - Additional deduction for IRAP on employee costsD.L. 201/2011
