Italian VAT & Corporate Tax Estimator

This tool helps foreign founders and international companies understand how VAT, IRES, IRAP and advance payments work in Italy — with short, practical explanations.

Important: this is a preliminary estimator. In Italy, final taxation depends on accounting rules, industry specifics, cross-border flows, and the exact legal structure.

How taxation works in Italy (simple overview)

VAT (IVA)

VAT is collected from customers on your invoices. You can usually offset it with VAT paid on business purchases.

The result is a VAT payable (you pay) or a VAT credit (you carry forward / request).

IRES (Corporate income tax)

Flat 24% tax on taxable profit.

Applies to Italian companies, registered branches, and permanent establishments.

IRAP (Regional tax)

Typically around 3.9% (varies by region). Often unexpected for foreign founders.

The base is not always identical to “profit”. This tool uses a simplified proxy.

Advance payments (Acconti)

In Italy, part of next year’s taxes is paid in advance, often based on the previous year.

This is a major cash-flow impact in year 2 and beyond.

Step 1 — Company profile

⚠️ PE note A Permanent Establishment can exist even without formal registration. If you have staff, offices, or contract-signing capacity in Italy, consider a tax review.

Step 2 — Annual data

Total sales/income (excluding VAT).
VAT charged to customers on invoices.
VAT paid on business purchases (deductible).
Core operating costs (excluding payroll).
Total annual payroll cost (gross, indicative).
Other deductible items (simplified).
