About this site

Purpose of this site

The Italy Flat Tax Calculator is a free, independent tool that helps you understand Italy regime for new residents, which lets qualifying individuals who move their tax residence to Italy pay a fixed annual substitute tax on all their foreign-source income, instead of normal progressive rates.

For people with substantial income arising outside Italy, the fixed annual charge can be far lower than ordinary taxation. This tool helps you compare the flat substitute tax against a rough ordinary-tax estimate so you can see the potential benefit.

How it works

The calculator runs entirely in your browser. You enter your foreign-source income; it applies the fixed annual substitute tax and an optional per-family-member charge, and compares that to an indicative ordinary-tax figure. Eligibility rules and the option for specific countries are simplified; Italian law governs.

Independent and neutral

This is an independently operated site that builds simple tools to remove the friction from complex tax-residency decisions. We are not a tax authority or advisory firm, and the calculator does not collect or store your figures; everything is processed locally in your browser.

Before you rely on it

The regime has strict eligibility conditions and a time limit, and the result here is an informational estimate, not tax advice. Please review our disclaimer and confirm with the Italian Revenue Agency or a qualified Italian tax adviser.
